CABI scientist Dr Arne Witt has shared his expertise on invasive alien plant species as part of a new paper which argues that healthy ecosystems are vital in reducing the risk of future pandemics - such as coronaviruses (including COVID-19) - that threaten human health.
The paper - 'Land use-induced spillover: priority actions for protected and conserved area managers' - is published as part of a special issue by the journal PARKS entitled 'COVID-19 and Protected Areas: Essential Reading for a World Haunted by a Pandemic.'
New scientific techniques are revealing the intricate role that proteins play in photosynthesis.
Despite being discovered almost 300 years ago, photosynthesis still holds many unanswered questions for science, particularly the way that proteins organise themselves to convert sunlight into chemical energy and at the same time, protect plants from too much sunlight.
Now a collaboration between researchers at the University of Leeds and Kobe University in Japan is developing a novel approach to the investigation of photosynthesis.
COLUMBUS, Ohio - Electric stimulation may be able to help blood vessels carry white blood cells and oxygen to wounds, speeding healing, a new study suggests.
The study, published in the Royal Society of Chemistry journal Lab on a Chip, found that steady electrical stimulation generates increased permeability across blood vessels, providing new insight into the ways new blood vessels might grow.
At the heart of Cygnus, one of the most beautiful constellations of the summer sky, beats a source of high-energy cosmic ray particles: the Cygnus Cocoon. An international group of scientists at the HAWC observatory has gathered evidence that this vast astronomical structure is the most powerful of our galaxy's natural particle accelerators known of up to now.
Alexandria, Va., USA -- Oral mucositis and taste dysfunction (dysgeusia) occurs in nearly all patients receiving head and neck radiotherapy and tremendously affects the quality of life and treatment outcome. The study "LiCl Promotes Recovery of Radiation-Induced Oral Mucositis and Dysgeusia" published in the Journal of Dental Research (JDR), investigated the hypothesis that lithium chloride (LiCl) can promote the restoration of oral mucosa integrity and taste function after radiation.
BUFFALO, N.Y. - A University at Buffalo researcher's recent work on dyslexia has unexpectedly produced a startling discovery which clearly demonstrates how the cooperative areas of the brain responsible for reading skill are also at work during apparently unrelated activities, such as multiplication.
Researchers at Princeton have determined how five cellular proteins contribute to an essential step in the life cycle of hepatitis B virus (HBV). The article describing these findings appeared March 11, 2021 in the journal Nature Communications.
CHAMPAIGN, Ill. -- Charitable donations account for about 2% of gross domestic product in the U.S., but it's not well-understood whether an event such as a deadly storm inspires increases in charitable giving or simply reallocates a fixed supply of donation dollars that would have otherwise gone to another cause.
A new paper from a team of University of Illinois Urbana-Champaign experts finds that, in the aftermath of catastrophic tornadoes, charitable giving to alleviate an unanticipated event doesn't necessarily crowd out monetary donations to other causes.
Messenger RNA COVID-19 vaccines greatly reduce risk of asymptomatic COVID-19 infection, spread to ot
ROCHESTER, Minn. -- Ten days after receiving a second dose of a messenger RNA, or mRNA, vaccine for COVID-19, patients without COVID-19 symptoms are far less likely to test positive and unknowingly spread COVID-19, compared to patients who have not been vaccinated for COVID-19. The Pfizer-BioNTech and Moderna messenger RNA vaccines for COVID-19 are authorized for emergency use in the U.S.
How do you turn "dumb" headphones into smart ones? Rutgers engineers have invented a cheap and easy way by transforming headphones into sensors that can be plugged into smartphones, identify their users, monitor their heart rates and perform other services.
LAWRENCE -- Much like coronavirus, circulating HIV-1 viruses mutate into diverse variants that pose challenges for scientists developing vaccines to protect people from HIV/AIDS.
"AIDS vaccine development has been a decades-long challenge partly because our immune systems have difficulty recognizing all the diverse variants of the rapidly mutating HIV virus, which is the cause of AIDS," said Brandon DeKosky, assistant professor of pharmaceutical chemistry and chemical & petroleum engineering at the University of Kansas.
Skoltech researchers were able to show that patterns that can cause neural networks to make mistakes in recognizing images are, in effect, akin to Turing patterns found all over the natural world. In the future, this result can be used to design defenses for pattern recognition systems currently vulnerable to attacks. The paper, available as an arXiv preprint, was presented at the 35th AAAI Conference on Artificial Intelligence (AAAI-21).
An enzyme called MARK2 has been identified as a key stress-response switch in cells in a study by researchers at Johns Hopkins Bloomberg School of Public Health. Overactivation of this type of stress response is a possible cause of injury to brain cells in neurodegenerative diseases such as Alzheimer's, Parkinson's, and Amyotrophic Lateral Sclerosis. The discovery will make MARK2 a focus of investigation for its possible role in these diseases, and may ultimately be a target for neurodegenerative disease treatments.
MADISON, Wis. -- Mexican wolves in the American Southwest disappeared more quickly during periods of relaxed legal protections, almost certainly succumbing to poaching, according to new research published Wednesday.
Fossil sites sometimes resemble a living room table on which half a dozen different jigsaw puzzles have been dumped: It is often difficult to say which bone belongs to which animal. Together with colleagues from Switzerland, researchers from the University of Bonn have now presented a method that allows a more certain answer to this question. Their results are published in the journal Palaeontologia Electronica.
