As human activity shapes Earth's climate, animals must increasingly adapt to new environmental conditions. The thermoneutral zone -- the ambient temperature range in which mammals can maintain their body temperature without expending extra energy -- is a key factor in estimating a species' ability to survive in a warming world.
Emotional, social and psychiatric problems in children and adolescents have been linked to higher levels of genetic vulnerability for adult depression.
University of Queensland scientists made the finding while analysing the genetic data of more than 42,000 children and adolescents from seven cohorts across Finland, the Netherlands, Norway, Sweden and UK.
Professor Christel Middeldorp said researchers have also found a link with a higher genetic vulnerability for insomnia, neuroticism and body mass index.
New research published in the British Ecological Society's Journal of Ecology finds that ash dieback is far less severe in the isolated conditions ash is often found in, such as forests with low ash density or in open canopies like hedges, suggesting the long term impact of the disease on Europe's ash trees will be more limited than previously thought.
Observations made with ESO's Very Large Telescope (VLT) have revealed for the first time that a star orbiting the supermassive black hole at the centre of the Milky Way moves just as predicted by Einstein's general theory of relativity. Its orbit is shaped like a rosette and not like an ellipse as predicted by Newton's theory of gravity. This long-sought-after result was made possible by increasingly precise measurements over nearly 30 years, which have enabled scientists to unlock the mysteries of the behemoth lurking at the heart of our galaxy.
The expansion of farmlands to meet the growing food demand of the world's ever expanding population places a heavy burden on natural ecosystems. A new IIASA study however shows that about half the land currently needed to grow food crops could be spared if attainable crop yields were achieved globally and crops were grown where they are most productive.
What The Study Did: Whether visual impairment is a risk factor for dementia was the focus of this observational study that included 1,000 older women who are participants in the Women's Health Initiative studies.
Authors: Suzann Pershing, M.D., M.S., of the Stanford University School of Medicine in Palo Alto, California, is the corresponding author.

Cold Spring Harbor, NY -- In the urgent battle to treat COVID-19 patients, a group of eleven international medical research organizations is investigating whether overactive immune cells that produce Neutrophil Extracellular Traps (NETs) cause the most severe cases. The consortium, called the NETwork, includes Cold Spring Harbor Laboratory, the Feinstein Institutes for Medical Research, and the Research Institute of the McGill University Health Centre (RI-MUHC).
University of Phoenix today announced Harris Poll findings regarding U.S. adults' perceptions of the COVID-19 pandemic. The survey found more than two in five (41 percent) of Americans say they are most concerned about experiencing increased anxiety; more so than not being able to pay their bills (33 percent), reduced job salary/work hours (26 percent), or losing their job/not being able to get a new job (22 percent).
A new poll finds that a majority of Americans now say the federal government should actively seek to reduce inequality, amid the worsening economic crisis produced by Covid-19. A national survey from Harris Insights & Analytics of 2,018 Americans, conducted April 7-9, 2020, finds that 78% of Americans agree that "considering the spread of coronavirus in the United States and its impact on the economy and the American people," it is "somewhat" or "very important" that "the U.S.
As the coronavirus disease (COVID-19) pandemic advances so does the uncertainty and evolution of the pandemic as it relates to nursing homes and long-term care facilities (LTCF). Early reports suggest the case fatality rate for those over 80, which constitutes nearly half of LTCF residents, is more than 15 percent. In areas where there is a shortage of ICU beds and respirators, even the most carefully thought out ethical approaches to rationing these resources will place older patients at a lower priority. LTCFs must be prepared to manage patients who have had or have COVID-19 infection.
Untwisting chains of atoms within a plastic polymer improves its ability to conduct electricity, according to a report by researchers, led by Nagoya University applied physicist Hisaaki Tanaka, in the journal Science Advances. The insight could help accelerate the development of wearable power sources for a vast number of Internet-of-things devices.
Since the beginning of the epidemic until March 25, the mobility restrictions implemented by the Italian government have avoided at least 200,000 hospitalizations and reduced the contagion transmission by 45% according to a study accepted for publication in the renowned journal PNAS, coauthored by a group of Italian scientists belonging to Politecnico di Milano, Università Ca' Foscari Venezia, University of Zurich, EPFL Lausanne, and Università di Padova.
University of Sheffield physicists take a step towards understanding why the universe is mostly matter and not antimatter
Research by an international collaboration indicates a difference in the behaviour of neutrinos and antineutrinos
The research is a major step forward and could further our understanding of the universe
Physicists from the University of Sheffield have taken a step towards understanding why the universe is made of mostly matter and not antimatter, by studying the difference between the two.

Osaka, Japan - Fertilization is a fundamental process in sexual reproduction when the combination of male and female gametes blends genetic material to create a new unique individual. Now, researchers from Japan have identified a new factor that may help orchestrate this vitally complex life event.
In a recent study, researchers from Osaka University and Baylor College of Medicine have identified a novel protein that takes part in sperm-oocyte membrane fusion during fertilization, and named it Fertilization Influencing Membrane Protein (FIMP).
