While the capability for organisms to work together is by no means novel, humans possess an unparalleled capacity for cooperation that seems to contradict Darwinian evolutionary principles. Humans often exhibit traits--such as sympathy, loyalty, courage, and patriotism--that prioritize collective well-being over individual fitness, and often cooperation occurs among individuals with no shared biological relation. This behavior, likewise, adapts in response to changing conditions, demonstrating the flexible nature of human cooperation.
As retrenchments continue to cloud the foreseeable future of businesses worldwide, new research from the University of South Australia, the University of Melbourne and RMIT indicates that some businesses will fare better than others - and it's all dependent on their type of human resource management system.
Understanding the principles of cancer evolution is important in designing a therapeutic strategy. A research group at The Institute of Medical Science, The University of Tokyo (IMSUT) announced a new simulation model that describes various modes of cancer evolution in a unified manner.
The Gerontological Society of America's highly cited, peer-reviewed journals are now publishing scientific articles on COVID-19. The following were published between April 21 and 29; all are free to access:
LISLE, Ill. (April 30) - In a groundbreaking study, an international team of 21 scientists led by Sean Hoban, PhD, Conservation Biologist at The Morton Arboretum in Lisle, Illinois, evaluated five genera spanning the plant tree of life (Hibiscus, Magnolia, Pseudophoenix, Quercus and Zamia) to understand how much genetic diversity currently exists in collections in botanical gardens and arboreta worldwide.
EUGENE, Ore. - April 30, 2020 - Entrepreneurs launching a crowdfunding campaign to fund new product development benefit by reaching out early to engage with potential end-users, say business researchers from three universities.
Emerging companies that did so, tweaking their prototypes in an active and open exchange, reached their fundraising goals and drew media coverage more easily than those that didn't, said Alex Murray of the University of Oregon and lead author of a study published online ahead of print in Organization Science.
Every now and then, scientists need to control the process of mixing liquids in vessels so small that the thinnest needle or even a hair wouldn't fit in there. At the same time, controlling the diffusion speed of molecules in the so-called microreactors is extremely important for the purposes of designing new drugs, conducting biological experiments and even to perform fast disease detection tests. Scientists from ITMO University and their colleagues from the Czech Academy of Sciences proposed to solve this problem by using the energy of light.
Researchers from the UPV/EHU, Cruces Hospital, the IVI Clinic Bilbao and Biocruces Bizkaia have discovered that the oocytes -immature ova- from obese and overweight women have lower concentrations of omega-3 fatty acids.
Neutron stars are among the densest objects in the universe. If our Sun, with its radius of 700,000 kilometres were a neutron star, its mass would be condensed into an almost perfect sphere with a radius of around 12 kilometres. When two neutron stars collide and merge into a hyper-massive neutron star, the matter in the core of the new object becomes incredibly hot and dense.
A study led by clinician scientists at RCSI University of Medicine and Health Sciences has found that Irish patients admitted to hospital with severe COVID-19 infection are experiencing abnormal blood clotting that contributes to death in some patients.
The study, carried out by the Irish Centre for Vascular Biology, RCSI and St James's Hospital, Dublin, is published in current edition of the British Journal of Haematology. (DOI: 10.1111/bjh.16749)
(Philadelphia, PA) - Like power lines in an electrical grid, long wiry projections that grow outward from neurons - structures known as axons - form interconnected communication networks that run from the brain to all parts of the body. But unlike an outage in a power line, which can be fixed, a break in an axon is permanent. Each year thousands of patients confront this reality, facing life-long losses in sensation and motor function from spinal cord injury and related conditions in which axons are badly damaged or severed.
WINSTON-SALEM, N.C. -- April 30, 2020 -- In an effort to rapidly provide specialized care for patients with coronavirus-like symptoms while protecting the safety of health care workers, doctors at Wake Forest Baptist Health created a special respiratory isolation unit from an existing 24-bed medical-surgical unit in the hospital in Winston-Salem.
The framework for this Person Under Investigation (PUI) unit was published in the April 13 issue of The Hospitalist, the official publication of the Society of Hospital Medicine.
An international team of researchers has outlined ways to manage different facets of life under the spread of the COVID-19 virus, ranging from how we can combat racially driven bias and fake news to how we can increase cooperation and better manage stress.
Its work, which appears in the journal Nature Human Behaviour, considers research stretching over the past half century to offer insights about how to address current circumstances.
PHARMACY experts at the University of Huddersfield are urging caution over claims that widely-available antimalarial drugs could be a "magic bullet" to prevent and cure CoVid-19. And the medicines can - if used rashly - have serious side effects.
Although there have been some encouraging signs from small-scale preliminary trials of the drugs chloroquine (CQ) and hydroxychloroquine (HCQ) when administered to coronavirus patients, the results are preliminary and should be treated with care, argue Dr Syed Shahzad Hasan and Dr Hamid Merchant.
Many of the drugs and medicines that we rely on today are natural products taken from microbes like bacteria and fungi. Within these microbes, the drugs are made by tiny natural machines - mega-enzymes known as nonribosomal peptide synthetases (NRPSs). A research team led by McGill University has gained a better understanding of the structures of NRPSs and the processes by which they work.
