RAVENNA, Italy (AP) — Nine musicians from the Syrian diaspora in Europe are playing Sunday in the 24th friendship concert conducted by Riccardo Muti, this year at the Paestum archaeological site in southern Italy, but the coronavirus pandemic blocked others from arriving directly from Syria.

The concert Sunday by the Luigi Cherubini Youth Orchestra founded by Muti, part of the Ravenna Festival summer series, is dedicated to Syrian archaeologist Khaled al-Asaad and Kurdish-Syrian politician Hevreen Khalaf, both of whom were slain during Syria’s ongoing civil war.

“These concerts give to Ravenna the possibility to be an important ambassador of peace and brotherhood from Italy,” Muti told The Associated Press earlier this month in Ravenna. Khalaf was killed by Syrian fighters trained by Turkey 2019, and al-Asaad was beheaded in 2015 by fighters of the Islamic State group after he refused to aid their destruction of the ancient Roman city at Palmyra, a U.N. world heritage site.

Muti launched the Roads of Friendship concert series in 1997 in Sarajevo, shortly after Bosnia’s 1992-1995 civil war ended, and has since traveled to cities wounded by war, including Beirut, as well as in ancient and historic sites to “reestablish ties” with places that have made history, including the ancient Roman amphitheater in the southern Syrian city of Bosra.

“We can build bridges between civilizations, between people, with music,” said Karoun Baghboudarian, a cellist living in the Netherlands who is playing in Sunday’s concert and who sang in the chorus during the 2004 concert in Bosra — before Syria devolved into war, a period when she said musicians’ lives flourished.

Her brother, Missak Baghboudarian, conducts the Syrian National Symphony Orchestra and had hoped to travel to Italy to conduct a concert in Ravenna and attend the Paestum concert of Beethoven’s Symphony No. 3, known as the “Heroic,” but was unable to travel because of travel restrictions imposed by the coronavirus. Instead, the Syrian National Symphony Orchestra streamed Beethoven’s “Heroic” from Damascus on July 2.

Karoun Baghboudarian said she hoped the concert would renew attention on Syrians’ suffering.

“We hope that Syria will come through the war and all the difficult situations as heroes, and that they can live normally,” she said by phone from Paestum.
Looters target Myanmar temple treasures in tourist slump

Bagan (Myanmar) (AFP)

A squad of armed police patrol Myanmar's sacred site of Bagan under the cover of night, taking on plunderers snatching relics from temples forsaken by tourists due to coronavirus restrictions.

Each evening as dusk falls, about 100 officers fan out across the plain of Bagan measuring 50 square kilometres (19 square miles), sweeping torches over the crumbling monuments to scour for intruders.

"Our security forces are patrolling day and night," Police Lieutenant Colonel Sein Win tells AFP.


"We have it under control for the moment, but it's a challenge."

The central Myanmar city is strewn with more than 3,500 ancient monuments — stupas, temples, murals and sculptures — and was finally added to the prestigious UNESCO world heritage list last year.

But the pandemic has stymied plans to capitalise on Bagan's new-found status.

The dearth of visitors means temples and hotels lie empty, crushing the livelihoods of locals and opening doors to opportunistic burglars.

In a spate of break-ins across the holy site in early June, robbers looted 12 different temples, swiping a range of relics, including copper stupas, ancient coins and jade jewellery.

The 35th Battalion regional police squad have been deployed to bolster local tourism police and firefighters, the teams ranging across the site by jeep, motorbike and foot.

"It's not easy to patrol as the area is so big," one police officer says through his face mask, worn by all on duty to protect against COVID-19.

They also need to be on their guard against the area's numerous venomous snakes, he adds, asking not to be named.

- Temple curse? -

For now, the extra security seems to have thwarted any break-ins at the most prestigious temples.

Some of the relics date back to the 11th-13th century, an era when Bagan was the capital of a regional empire.

This is the first time in decades the site has been so seriously targeted, says Myint Than, deputy director of Bagan's archaeological department, as he shows at one stupa how the looters scaled the walls to enter from the roof.

"When there were tourists here, there were no burglaries," he explains, adding he believes this is the work of outsiders.

Even if locals' livelihoods have been devastated by the tourist downturn, he says he does not believe they would "betray their heritage".

Times are hard in an area dependent on tourism.

Bagan welcomed nearly half a million visitors in 2019, while this year the figure was 130,000 up until the country's New Year festival in April and much of the area has been closed to tourists since.

Hotels and restaurants lie shuttered while the hawkers and tuk-tuk drivers not lucky enough to clinch rare construction or farming work wait in vain for customers among the deserted lanes connecting the temples.

Souvenir seller Wyne Yee, 46, says the money she makes in April alone usually keeps food on her family's table for the following six months.

"But this year we have no money left," she says wistfully.

She says she is saddened by the desecration of the temples but — like others in the area — is convinced a curse will see the crooks receive their comeuppance.

"The Bagan temples will not tolerate it," she says. "The robbers will be dealt with."

Increases in groundwater levels and volumes after large earthquakes have been observed around the world, but the details of this process have remained unclear due to a lack of groundwater data directly before and after an earthquake strikes. Fortunately, researchers from Kumamoto and Kwansei Gakuin Universities (Japan) and UC Berkley (US) realized that they had a unique research opportunity to analyze groundwater level changes around Kumamoto City after large earthquakes struck the area in 2016 .
Changes in the hydrological environment after an earthquake, like ponds or wells drying-up, the sudden appearance of running water, or a rise in water levels have been recorded since Roman times. Various theories have been proposed for the cause of such changes, such as fluctuations in pore water pressure (the pressure of groundwater held in the pores or gaps of rocks and soil), increased water permeability, and water movement through new cracks. To identify the actual cause, data must be collected from observation sites in wells, water sources, and rivers. However, especially in the case of inland earthquakes, it is generally rare for these sites to be spatiotemporally arranged in an area where a large earthquake has occurred. Additionally, it is even rarer to have enough data to compare before and after the disaster. These difficulties have been a roadblock to obtaining a clear picture of how hydrological environments change after earthquakes.
Kumamoto City, on the southern Japanese island of Kyushu, is famous for its water. Nearly 100% of the city's drinking water is sourced from groundwater in the area so there are many observation wells in the area that continuously record water level and quality data. In the early morning (Japan time) of April 16, 2016, a magnitude 7.0 earthquake struck the city which resulted in a wealth of groundwater data both before and after the earthquake. Kumamoto University researchers recognized this unique opportunity to assess how earthquakes can change hydrological environments in more detail than ever before, so they established an international collaboration to study the event.
An abnormal rise in groundwater level occurred after the main shock and was particularly noticeable in the recharge area of the groundwater flow system. The water levels peaked within a year after the main shock at around 10 meters and, although it has calmed down thereafter, water levels were still high more than three years later. This was thought to be due to an inflow of water from a place not part of the pre-earthquake hydrological cycle, so researchers attempted to determine the sources by using stable isotope ratios of water.
The stable isotope ratios of water on Earth's surface change slightly with various processes (evaporation, condensation, etc.) so they become unique marker values depending on location. These markers make it possible to determine the processes that affected a water sample as well as its source.
A comparison of the before-and-after sets of stable isotope ratios revealed that, prior to the earthquake, groundwater in the Kumamoto City area came mainly from low-elevation mountain aquifers, soil water in recharge areas, and seepage from the central Shirakawa river area. After the earthquake, the researchers believe that seismic fractures on the west side of Mt. Aso increased the permeability of the mountain aquafer which released groundwater toward the recharge area of the flow system and increased water levels. Furthermore, groundwater levels in the outflow area that had dropped immediately after the main shock were nearly restored within just one year.
"Our research is the first to capture the hydrological environment changes caused by a large earthquake in detail," said study leader Associate Professor Takahiro Hosono. "The phenomenon we discovered can occur anywhere on Earth in areas with climate and geological conditions similar to Kumamoto. We hope our research will be useful both for academics and the establishment of guidelines for regional water use in a disaster."

In the Arctic, spring snowmelt triggers fresh CO2 production

The Arctic is warming faster than the rest of the world and snowmelt is speeding it up with rapid soil warming and increased CO2 in the air

Studies have shown the Arctic is warming roughly twice as fast as the rest of the world, and its soil holds twice the amount of carbon dioxide as the atmosphere. New research from San Diego State University finds that water from spring snowmelt infiltrates the soil and triggers fresh carbon dioxide production at higher rates than previously assumed.
This is in addition to trapped carbon escaping from the soil, which means an acceleration in warming that is not quite accounted for in current measurement techniques.
SDSU post-doctoral fellow Kyle Arndt and ecosystem ecologist Donatella Zona spent several years assessing the situation on the ground in Utqiagvik (formerly Barrow), Alaska and analyzing their findings once they returned to San Diego.
The cold season is an essential component of the annual carbon balance, and it was assumed to have a negligible impact on carbon production.
By analyzing soil core samples, what they found was that it wasn't just trapped greenhouse gases that were escaping but also likely increasing fresh production of carbon during the spring thaw.
Published June 30 in Global Change Biology, their study discovered that cold thaw accounts for nearly half of carbon emissions which can offset the summer uptake or absorption of carbon dioxide by vegetation. Their findings fill a gap in data that has long existed because harsh winters and springs made the Arctic difficult to access to conduct studies.
"Earlier we didn't have this data, but now that we do, we are seeing that these ecosystems are rapidly warming," Arndt said. "Many models already predict the Arctic will turn into a CO2 source, but they may be underestimating the size of the source if this spring process is not taken into account."
Arndt, first author of the paper, began visiting Utqiagvik in summer 2016 to maintain equipment set up by SDSU ecologist Walter Oechel, who has been working for nearly 40 years in these Arctic sites.
Using eddy covariance, a technique to measure carbon dioxide movement between the soil and atmosphere as well as ground and air temperatures, ground heat flux and snow depth, Arndt measured fluxes.
Heat flux is the energy transferred per unit of surface area for a given period of time, and it's challenging to collect it during the freeze. Arndt "came up with the idea of measuring it during spring snow melt, building on the need to fill a gap in data on the cold season Arctic heat fluxes," Zona said.
Arndt also worked with SDSU microbiologist David Lipson who collected soil core samples, which helped him and Zona understand the physical properties of the soil during the spring and fall season.
Arndt ascertained that fresh CO2 production was happening when "we found air pockets in the middle of the soil core that allowed for the melted snow to rush in. The snowmelt is rich in oxygen which helps with the production of carbon dioxide."
Iron is one of the many minerals soil contains. Their analysis showed the iron was completely oxidized, which can only happen if fresh oxygen in the soil bonds with and oxidizes the iron. The researchers found a steady rise in CO? emissions during this thawing period further suggesting the occurrence of production at this time.
Simpler models of data analysis may miss the rapid warming that happens due to snowmelt, when there's a rapid introduction of oxygen leading to the warming.
"There's a lot more going on in the soil than we previously thought," Arndt said. "Nature is efficient in that it breaks down lighter compounds preferentially to heavier ones, creating unique isotope signatures, kind of like fingerprints. By looking at isotopes, we can tell how long the compounds have been there and the source of the carbon emitted."
Arndt and Zona are planning to focus on isotopic analysis next, to reconstruct the age of the compounds in the samples, and the longer scale implications of these results.
"We will look for long-term trends in carbon dioxide release and how the heat fluxes have been changing over the last decade," Zona said.

New research examines links between religion and parental support from non-family members

"Be fruitful and multiply" says the Bible, and worldwide religious people tend to have more children than their secular counterparts. New research suggests that this "multiplying" may be the result of the higher levels of support from non-family members that church-going women receive, and that these greater levels of support are also associated with positive developmental outcomes for children.
The report Church attendance and alloparenting: An analysis of fertility, social support, and child development among English mothers, published this month in Philosophical Transactions of the Royal Society B, the world's oldest English language journal, explored how church attendance is associated with social support and fertility, and how help from outside the family influences child development.
Lead author and University of Otago Religion programme head Dr John Shaver says the research attempts to resolve a paradox.
"That religious people tend to have more children is relatively well known across the social sciences, but from an evolutionary perspective, religious communities' high fertility is puzzling."
Shaver says that previous studies have found that sibling number is negatively related to a child's cognitive and physiological development, as well as their socioeconomic success in adulthood -because parents have less time, and fewer resources to invest in their development.
"The expectation, based on these findings, would be that due to differences in family sizes, children born to religious parents would exhibit poorer developmental outcomes than children born to secular parents. There haven't really been studies that compare the success of religious and secular children, but the available evidence suggests that children born to religious parents fare just as well as those born to secular parents. We've been interested in explaining this paradox of religious fertility."
Using 10 years data collected from the Children of the 90s health study, the report's authors tested the hypothesis that religious cooperation extends to alloparenting (investment in children by people other than the child's parents), that higher levels of social support for religious mothers was associated with their fertility, and their children's development.
The study found that mothers who received help from members of their congregation had higher fertility over time.
The research also confirmed that children with more siblings scored lower on three cognitive tests: when they entered school (aged 4-5), one year later (aged 5-6), and when they were eight.
"Our study reveals known biases in these and similar cognitive tests - such as that the children of wealthier and better educated mothers scored higher on these tests. We found, though, that a mother's social support and aid from co-religionists were both associated with higher child test scores, particularly at later stages of development. This suggests that women's social networks positively affect her child's cognitive development, and our analyses also suggest that religious women have stronger support networks," Dr Shaver says.
Dr Shaver says while the findings only supported some hypotheses, they were mostly consistent with the idea that religions in modern environments support cooperative breeding strategies: women who receive help from members of their congregation have higher fertility, and this aid, as well as more general forms of social support, were both associated with improved child cognitive development.
"By positively influencing social support, religion in the UK may help some women have more children, without sacrificing the success of these children."
Researching the evolutionary dynamics surrounding religion's influence on family size and child success is not just of interest to the scholarly community.
"Due to its relevance for economic and social development, health, and demographic projections, we expect our project will be of significant interest to governments, NGOs, and public policy officials," he says.

New Yorkers grow more hesitant about a return to normalcy, poll shows

Employment and housing woes continue

New Yorkers continue to report much higher than normal rates of depression and anxiety, but much less than at their peak in mid-April. As they witness the surge in COVID-19 cases in states that re-opened early, New Yorkers have also grown significantly more hesitant about resuming normal activities than they reported in May. Employment and housing worries remain a serious concern for many. These are the major findings of the 13th city and statewide tracking survey from the CUNY Graduate School of Public Health and Health Policy (CUNY SPH), June 26-28.
As May 2020 began, 65% of New Yorkers said they would see their doctor for a routine visit beginning at the start of the next month. In June, that number dropped to 33%. In early May, 46% said they would go for a haircut starting June 1, but by the end of June, only 33% said they would do so as of July 1. The number who thought they would go to a restaurant after the first of the following month dropped from 31% to 20%. Moreover, a far greater number of respondents now say they plan to wait for a safe and effective vaccine to be widely available before they take part in many routine activities. In May, for example, 31% said they would wait for a vaccine before going to an outdoor concert; in June, nearly twice that number (60%) said they would wait for a vaccine.
Less than a third of respondents believe that public schools (27%) and colleges and universities (31%) should reopen for regular classes in the fall. A majority (54%) do not think the pandemic will end until a vaccine is created.
"People follow the news," said Dr. Ayman El-Mohandes, Dean of CUNY SPH. "COVID-19 is under better control in New York now, but people see that it is devastating other cities, states and countries, and they do not want to let their guard down. People here also seem to have become resigned to COVID-19. They don't see the pandemic ending within a finite period of time, instead they link its resolution to the availability of a safe and effective vaccine."
Serious Economic Pressures Continue for Many
Respondents still face serious economic challenges. One in five respondents (20%) who rent their homes said they would not be able to pay their rent this month, while 10% of homeowners said they would not be able to pay their mortgage. This situation remains unchanged since a mid-April CUNY SPH survey, which reported that 23% of respondents were unable to pay their rent, and 11% were unable to pay their mortgage.
Of those facing difficulties with rent or house payments, 51% believe they will be evicted, and 2% said they have already been evicted. The government's moratorium on evictions in New York expires on July 6, although some limited protections will remain in place through the end of August.
About one-fourth (26%) of respondents said they had lost their job as a consequence of the pandemic, of whom 46% were terminated and 54% were furloughed. Of those who were terminated, only 54% said they had found another job; of those who were furloughed, only 36% have been asked to return to their previous work.
It is not surprising, then, that more New Yorkers see the economy as worsening (44%) rather than improving (28%). Three in ten respondents remain worried about paying for housing (30%) and more than a quarter (26%) are concerned about employment.
SNAP Numbers Fail to Keep Pace with the Reality of Food Insecurity
About one-third (32%) of the current survey's respondents report receiving food from SNAP or local non-profit organizations, which is virtually unchanged from late April.
"Despite the determined efforts of public programs to improve access to food assistance, it is disturbing that, four months into the epidemic, less than a third of New Yorkers report receiving such help," said Nicholas Freudenberg, Distinguished Professor of Public Health and Director of the CUNY Urban Food Policy Institute. "This suggests an ongoing gap, as our survey in late May found that 44% of households were experiencing food insecurity. To reduce the high levels of food insecurity that threaten present and future physical and mental health in New York City, public food programs will need to do more to reach those in need."
Testing on the Rise
Indicative of a more positive trend, a greater proportion of New Yorkers (42%) reported last weekend that either they or a member of their household has been tested for COVID-19 since March, with three-fourths (75%) of those being tested within the last four weeks. Of this group, 31% reported that the test had been positive, which represents about one in eight (13%) of all the households in the overall survey population. People who reported being tested in previous CUNY SPH surveys were more likely to report testing positive, which suggests that testing was previously being made available only to individuals who appeared to be ill.
Social Issues
About a quarter (26%) of New Yorkers think the coronavirus appears to be a greater threat to the future of the city than racism and police violence (16%). African Americans rated racism slightly higher (20%) and the coronavirus slightly lower (20%) than respondents overall.
However, almost three in five (58%) of all respondents rated the two threats as equal.
Almost three in ten (28%) of respondents said they took part in the recent protests against racism and police brutality, of whom 60% said it was their first time doing so.
Mental Health
Almost half (46%) of respondents report they have not interacted with family and friends outside of their home in the last two weeks, 27% said they have done so once, 21% said two to three times, with 3% reporting four to five times and another 3% reported six times or more.
New Yorkers appear to be habituating to the stress of the pandemic, as mental health symptoms appear to be steadily declining since their peak in mid-April, when mental health risk rates were about 34-44%. Now, only 21% and 28% of New Yorkers are reporting depression and anxiety risks (i.e., experiencing symptoms half of the time in the past two weeks), respectively.
"Increases in social interactions with family and friends, as well as high participation by New Yorkers in social movements, may be buffering the mental health effects of the pandemic," says Dr. Victoria Ngo, Director of the Center for Innovation in Mental Health at CUNY SPH. "However, only 8% of our latest respondents report that they used free emotional support assistance from city and state resources, like the New York State Office of Mental Health, ThriveNYC, NYCWell, etc. This is worrisome as it suggests that these free resources are not reaching the community."
Trusted Sources of COVID-19 Information
More than a fourth of New Yorkers reported television news (26%) their most trustworthy source of information about coronavirus, and a similar number (25%) said they trusted the CDC, while 15% said Governor Andrew Cuomo, 10% the WHO, 6% social media, 6% the Trump administration, 5% print news, and 3% family and friends.

Survey methodology
The CUNY Graduate School of Public Health and Health Policy (CUNY SPH) survey was conducted by Emerson College Polling from June 26-28, 2020 (week 16). This tracking effort started March 13-15 (week 1).
The sample for the NY Statewide and New York City results were both, n=1,000, with a Credibility Interval (CI) similar to a poll's margin of error (MOE) of +/- 3 percentage points. The data sets were weighted by gender, age, ethnicity, education, and region based on the 2018 1-year American Community Survey model. It is important to remember that subsets based on gender, age, ethnicity, and region carry with them higher margins of error, as the sample size is reduced. In the New York City results, data was collected using an Interactive Voice Response (IVR) system of landlines (n=403), SMS-to-online (n=332), and an online panel provided by MTurk and Survey Monkey (n=232). In the Statewide results, data was collected using an Interactive Voice Response (IVR) system of landlines (n=404), SMS-to-online (n=329) and an online panel provided by MTurk and Survey Monkey (n=267).
In the statewide survey, regions were broken out into the following:
Region 1: Long Island 14.7% (USC1-4), Shirley, Seaford, Glen Cove, Garden City
Region 2: NYC 45.3% (USC 5-16) Queens, Brooklyn, Manhattan, Staten Island, Bronx
Region 3: Upstate 40% (USC 17-27): Albany, Harrison, Carmel, Rhinebeck, Amsterdam, Schuylerville, Utica, Corning, Irondequoit, Buffalo, Rochester

Treatments tested for invasive pest on allium crops; onions, garlic, leeks

CORNELL UNIVERSITY

ITHACA, N.Y. - Native to Europe but discovered in Pennsylvania in 2015, the Allium leafminer is a fly whose larvae feed on crops in the Allium genus, including onions, garlic and leeks.
Since its arrival in the U.S., it has spread to New York, Connecticut, Massachusetts, Maryland and New Jersey, and is considered a major agricultural threat. A Cornell University-led team of researchers field-tested 14 active ingredients in insecticides, applied in a variety of methods, to understand the best treatment options.
The researchers' findings are described in a study, "Managing Allium Leafminer: An Emerging Pest of Allium Crops in North America," published in the Journal of Economic Entomology.
The research team, led by senior author Brian Nault, professor of entomology at Cornell AgriTech and one of the nation's leading Allium leafminer management experts, found that several traditional chemical insecticides worked best against the invasive insect.
"Problems with the Allium leafminer tend to be worse on organic farms where highly effective management tools - synthetic insecticides - are not used," Nault said.
The Allium leafminer (Phytomyza gymnostoma) has two generations annually, with adults emerging in April and again in mid-September. These two cycles are separated by a pause in the summer, when most onions are grown, which allows the crop to escape the pest. Also, onion bulbs expand rapidly, which does not allow the leafminer maggot time to effectively feed.
Crops with green foliage during either adult leafminer generation are most at risk. In the northeastern U.S., these include chives, scallions and garlic in the spring, and scallions and leeks in the fall. Wild alliums, which cross both generations, can be a reservoir where the insects to grow.
Larvae start feeding at the tops of plants and migrate toward the base to pupate. The larvae can destroy vascular tissue, which can lead to bacterial or fungal infections that cause rot.
The research team tested various management strategies with onions, leeks and scallions in Pennsylvania and New York in 2018 and 2019. Spraying chemical insecticides (dinotefuran, cyantraniliprole and spinetoram) was the most consistent and effective method, with up to 89% reduction in damage and up to 95% eradication of the insect. Dinotefuran and cyantraniliprole applied through a drip irrigation technique were not effective.
Other insecticides (abamectin, acetamiprid, cyromazine, imidacloprid, lambda-cyhalothrin, methomyl and spinosad) also reduced densities of Allium leafminers. Spinosad applied to bare roots, or in plug trays for plant starts, reduced the insect's damage after transplanting by 90%.
Though Allium leafminers have not been an issue in onions so far, researchers and farmers are concerned they may become a problem if they gain traction and move west, where onions are a major crop. "This has been a huge concern for the U.S. onion industry," Nault said.

Consumption of products derived from vulnerable wildlife species pervasive in Laos

Demand for bear and serow could precipitate 'conservation challenge,' authors say
SAN DIEGO ZOO GLOBAL
"Our results indicate the importance of identifying emerging trends in wildlife consumption, which can inform efforts to halt population declines before they become full-blown crises," said Elizabeth Oneita Davis, Ph.D., a postdoctoral associate in Community Engagement at San Diego Zoo Global. She co-authored the study, published in April in the journal Animals, with Jenny Glikman, Ph.D., an associate director in Community Engagement at San Diego Zoo Global.
"The research presented here represents a critical first step towards a conservation management solution in northern Laos that incorporates the emerging threat of consumption of serow, which may be excluded from management plans directed at conserving more 'charismatic' fauna," said Davis.
Unsustainable wildlife consumption is widespread in Southeast Asia. Exports to neighboring China and Vietnam have led to the extirpation of tigers and Javan rhinos in Laos, the authors said. Less is known, though, about the demand for wildlife products within Laos. To learn more about use patterns, Davis and Glikman interviewed 100 adults in 18 villages, in the Luang Prabang region of the country.
The most commonly used substances, consumed by about a quarter of those interviewed, were derived from the bile or gallbladder of sun bears and Asiatic bears. While use of bear products in the region had been documented, this study suggests consumption may be more common than previously thought. The second most-consumed items, used by 7% of respondents, were derived from serows. Products derived from serows and bears are similar in form and use, often being made into topicals or consumables to treat bruises or fight fatigue. However, serow products are less expensive than comparable bear products.
Sun bears and Asiatic black bears are listed as Vulnerable on the International Union for Conservation of Nature Red List of Threatened Species. The Chinese serow is listed as Near Threatened, but the IUCN is in the process of changing its status to the more-urgent Vulnerable, the study authors said.
Overall, interviewees reported they had used or knew someone who had used a wide variety of products derived from animals ranging from elephants to tigers, snakes, porcupines, monkeys and bats. Approximately half of respondents said they viewed wildlife products as a form of traditional medicine. A majority of the species consumed were listed as Vulnerable or Least Threatened on the Red List of Threatened Species.
"Our results of present and prevalent demand for wildlife in northern Laos indicate both that enforcement efforts are not working and that the Laos government's goals of reducing wildlife trade may be challenging to achieve," Davis said.
It isn't known if the current harvest of serows in Laos is sustainable. But it is possible that demand could increase sharply if those who consume bear products turn to less-pricey serow products instead. If that happens, the ungulates "may suffer a sudden, serious and rapid decline in the next decade," the authors wrote.

States with highest income inequality experienced a larger number of COVID-19 deaths

UNIVERSITY OF CALIFORNIA - LOS ANGELES HEALTH SCIENCES
FINDINGS
States with the highest level of income inequality had a larger number of COVID-19-related deaths compared with states with lower income inequality. New York state, with the highest income inequality, had a mortality rate of 51.7 deaths per 100,000. This is 125 times greater than Utah, the state with the lowest income inequality and which had a mortality of 0.41 per 100,000 at the end of the period studied. Looking at the top three in each category, New York was followed by Louisiana with 19 deaths per 100,000, and Connecticut with 16.9 deaths per 100,000. States in addition to Utah with the lowest COVID deaths that were linked to income inequality were South Dakota, with 0.7 deaths per 100,000 and North Dakota, which had one death per 100,000.
BACKGROUND
As the COVID-19 pandemic continues, data from New York City and Chicago shows that African Americans and Hispanics have experienced higher rates of infection and death. These groups are largely low income, have less access to health care, hold essential jobs limiting their ability to maintain social distancing, and frequently live in extended family households where the infection risk is higher.
METHODS
The researchers limited their analysis to January 22 through April 13, 2020. They used data on cases and deaths from the COVID-19 Dashboard maintained by the Center for Systems Science and Engineering at Johns Hopkins University. State income inequality data came from the 2018 American Community Survey as measured by the Gini index, a statistical formula used to measure income distribution.
The authors note some limitations in the findings, such as the effect of co-morbidities on death rates and weaknesses in state-level data that might have missed other associations between inequality and COVID-19 infections.
IMPACT
The findings suggest that social factors such as income inequality may explain why some states experienced more COVID-19 deaths than others. The findings could be useful in developing policies to mitigate the effects of the pandemic on socio-economically vulnerable populations.

Men more likely than women to be seen as brilliant

New global study finds an unconscious stereotype linked to gender
NEW YORK UNIVERSITY
Men are more likely than are women to be seen as "brilliant," finds a new study measuring global perceptions linked to gender. The work concludes that these stereotyped views are an instance of implicit bias, revealing automatic associations that people cannot, or at least do not, report holding when asked directly.
The research, which appears in the Journal of Experimental Social Psychology, was conducted by scientists at New York University, the University of Denver, and Harvard University.
"Stereotypes that portray brilliance as a male trait are likely to hold women back across a wide range of prestigious careers," observes Daniel Storage, an assistant professor in the University of Denver's Department of Psychology and the paper's lead author.
"Understanding the prevalence and magnitude of this gender-brilliance stereotype can inform future efforts to increase gender equity in career outcomes," adds Andrei Cimpian, an associate professor in NYU's Department of Psychology and the paper's senior author.
Previous work by Cimpian and his colleagues has suggested that women are underrepresented in careers where success is perceived to depend on high levels of intellectual ability (e.g., brilliance, genius), including those in science and technology.
Less understood are the factors that explain this phenomenon. To address this, the new Journal of Experimental Social Psychology study explored the potential impact of stereotypes. For example, perhaps the qualities of genius and brilliance are associated in people's minds with men more than with women--and, as a result, women are less encouraged to pursue these fields--or the atmosphere of these fields is less welcoming to women.
However, accurately measuring stereotyping is a challenge. People are often reluctant to admit they have stereotypes, so asking directly about these beliefs is unlikely to provide an accurate measure of whether they endorse the idea that brilliance is more common among men than it is among women.
To overcome this methodological obstacle, the researchers adopted a test that is geared to measure stereotyping indirectly. Here, the aim is to capture implicit stereotypes--or the automatic associations that come to mind between certain traits (e.g., brilliance) and certain groups (e.g., men). This is in contrast to explicit stereotyping, in which we knowingly and verbally ascribe traits to groups of people.
The team employed a long-established tool, the Implicit Association Test (IAT), which measures the degree of overlap between concepts (e.g., brilliant and male) without explicitly asking subjects whether or not they hold stereotyped views.
The IAT is essentially a speeded sorting task. In the study, participants saw a series of stimuli (such as a picture of a woman or the word "brilliant") on a computer screen and were asked to sort them into two categories by pressing either the E or the I key on their keyboard. For example, in some trials participants were asked to press E if they saw a stimulus that is related to either the category male or the trait brilliant. On other trials, the sorting rule was different. For example, the gender categories were swapped such that participants had to press E if they saw a stimulus that is related to either the category female or the trait brilliant.
The logic of the IAT, the authors explain, is as follows: If brilliant is more associated with male than with female in people's minds, then participants will be faster to sort the stimuli when brilliant and male are paired with the same response key--because the stereotype makes these two concepts seem like they "go together"--than when brilliant and female are paired.
Across a series of five studies, which included U.S. women and men, U.S. girls and boys (ages 9 and 10), and women and men from 78 other countries, the researchers consistently found evidence for an implicit stereotype associating brilliance with men more than with women. The magnitude of this stereotype was striking as well--for example, it was similar in strength to the implicit stereotype that associates men more than women with careers (and women more than men with the family), which was identified in earlier work.
The team also gauged explicit stereotypes, directly asking subjects whether they believed that men are more brilliant than women. In marked contrast to the implicit stereotyping measures, subjects reported disagreeing with this idea--and, in one study, explicitly associated the quality of being "super smart" with women more than with men. The finding is consistent with previous scholarship showing that people are unlikely admit to stereotyping, reinforcing the importance of measuring such perceptions through more subtle means.
Tessa Charlesworth, a doctoral student at Harvard University and co-author of the paper, notes that "a particularly exciting finding from this work is that, if anything, people explicitly say that they associate women with brilliance. Yet implicit measures reveal a different story about the more automatic gender stereotypes that come to mind when thinking about brilliance."
