Small-scale fisheries offer strategies for resilience in the face of climate change

2021-03-03
(Press-News.org) Coastal communities at the forefront of climate change reveal valuable approaches to foster adaptability and resilience, according to a worldwide analysis of small-scale fisheries by Stanford University researchers.

Globally important for both livelihood and nourishment, small-scale fisheries employ about 90 percent of the world's fishers and provide half the fish for human consumption. Large-scale shocks -- like natural disasters, weather fluctuations, oil spills and market collapse -- can spell disaster, depending on the fisheries' ability to adapt to change. In an assessment of 22 small-scale fisheries that experienced stressors, researchers revealed that diversity and flexibility are among the most important adaptive capacity factors overall, while access to financial assets was not as important for individual households as it was at the community scale. The research was published Jan. 23 in the journal END

Study: Bahamas were settled earlier than believed

2021-03-03
Humans were present in Florida by 14,000 years ago, and until recently, it was believed the Bahamas - located only a few miles away - were not colonized until about 1,000 years ago. But new findings from a team including a Texas A&M University at Galveston researcher prove that the area was colonized earlier, and the new settlers dramatically changed the landscape. Peter van Hengstum, associate professor in the Department of Marine and Coastal Environment Science at Texas A&M-Galveston, and colleagues have had their findings published in PNAS (Proceedings of the National Academy of Sciences). Researchers generated a new ...

Mental health treatment rate rose early in pandemic

2021-03-03
A detailed analysis of mental health treatment trends during the COVID-19 pandemic found a 7% increase in visits during the initial shelter-in-place period in 2020, compared with the same 3-month period in 2019. The study, published in The Journal of Clinical Psychiatry March 3, examined patient visits for psychiatric diagnoses among members of Kaiser Permanente in Northern California. The greatest increases in visits were for substance use (up 51%), adjustment disorder (up 15%), anxiety (up 12%), bipolar disorder (up 9%), and psychotic disorder (up 6%). Adjustment disorder is diagnosed when someone responds ...

Conquering the timing jitters

Conquering the timing jitters
2021-03-03
Breakthrough greatly enhances the ultrafast resolution achievable with X-ray free-electron lasers. A large international team of scientists from various research organizations, including the U.S. Department of Energy's (DOE) Argonne National Laboratory, has developed a method that dramatically improves the already ultrafast time resolution achievable with X-ray free-electron lasers (XFELs). It could lead to breakthroughs on how to design new materials and more efficient chemical processes. An XFEL device is a powerful combination of particle accelerator and laser technology producing extremely brilliant and ultrashort pulses of X-rays for scientific research. "With this technology, scientists can now track processes that occur within millions of a billionth of ...

Camera traps reveal newly discovered biodiversity relationship

Camera traps reveal newly discovered biodiversity relationship
2021-03-03
HOUSTON - (March 3, 2021) - In one of the first studies of its kind, an analysis of camera-trap data from 15 wildlife preserves in tropical rainforests has revealed a previously unknown relationship between the biodiversity of mammals and the forests in which they live. Tropical rainforests are home to half of the world's species, but with species going extinct at a rapid pace worldwide, it's difficult for conservationists to keep close tabs on the overall health of ecosystems, even in places where wildlife is protected. Researchers found that observational data from camera traps can help. "In general, rainforest ecosystems ...

'Best case' goals for climate warming which could still result in massive wildfire risk

Best case goals for climate warming which could still result in massive wildfire risk
2021-03-03
Under the 2015 Paris Agreement, the United Nations Framework Convention on Climate Change agreed to pursue efforts to limit the temperature increase to 2.0°C and, ideally, to 1.5°C, over preindustrial levels. However, even before that treaty was signed, scientists had already warned that those "best case" targets were unlikely to be achievable. Consequently, many fire weather studies are built with models that simulate much higher levels of climate warming. Recently, researchers from South Korea, Japan, and the United States have found that by projecting the fire weather conditions under two mildly varying warming levels -- one in which the global climate warms by 1.5°C and the other by 2°C -- even just a half-degree of warming could ...

How to track the variants of the pandemic faster

How to track the variants of the pandemic faster
2021-03-03
"What scientists have achieved in a year since the discovery of a brand-new virus is truly remarkable," says Emma Hodcroft from the Institute of Social and Preventive Medicine (ISPM) of the University of Bern, first author on the piece, "but the tools scientists are using to study how SARS-CoV-2 is transmitting and changing were never designed for the unique pressures - or volumes of data - of this pandemic." SARS-CoV-2 is now one of the most sequenced pathogens of all time, with over 600,000 full-genome sequences having been generated since the pandemic began, and over 5,000 new sequences coming in from around the world every day. ...

Learning about health from trusted sources may help teens battle depression

2021-03-03
UNIVERSITY PARK, Pa. -- Depression can be a common problem for teens and adolescents, and while many treatments exist, they don't always work for everyone. A new study found that feeling more informed about their health may help teens take better care of themselves, leading to less depressive symptoms. The researchers also found that trust played a factor in whether receiving health information improved depression. The more that adolescents trusted their parents or teacher as a credible source of health information, the more likely they were to ...

Independent music squashed out of streaming playlists and revenue

2021-03-03
Bands and artists on independent record labels get less than their fair share of access to the most popular playlists on streaming platforms such as Spotify - argues a new paper from the University of East Anglia. The paper, published today, looks at whether streaming platforms offer a level playing field for artists and record labels. It finds that major labels have an unfair advantage when it comes to playlist access - and that they take the lion's share of subscription revenue as a result. As a possible remedy, the research team suggests changing the payment system, so that royalties generated by individual listener subscriptions go direct to the labels, bands and artists they are listening to. They also ...

Study contributes to evidence for potential association between blood group a and COVID-19

2021-03-03
As researchers around the world work to identify and address risk factors for severe COVID-19, there is additional evidence that certain blood types could be associated with greater risk of contracting the disease. A new Blood Advances study details one of the first laboratory studies to suggest that SARS-CoV-2, the virus that causes COVID-19, is particularly attracted to the blood group A antigen found on respiratory cells. In the study, researchers assessed a protein on the surface of the SARS-CoV-2 virus called the receptor binding domain, or RBD. The RBD is the part of the virus that attaches to the host cells, so it is an important research target for ...

Vaping marijuana associated with more symptoms of lung damage than vaping or smoking nicotine

2021-03-03
Adolescents who vape cannabis are at greater risk for respiratory symptoms indicative of lung injury than teens who smoke cigarettes or marijuana, or vape nicotine, a new University of Michigan study suggests. The result challenges conventional wisdom about vaping nicotine, says the study's principal investigator, Carol Boyd, the Deborah J. Oakley Collegiate Professor Emerita at the U-M School of Nursing. "I thought that e-cigarettes (vaping nicotine) would be the nicotine product most strongly associated with worrisome respiratory symptoms," she said. "Our data challenges the assumption that smoking cigarettes ...
