Treating equine donor stem cells with a growth factor called TGF-β2 may allow them to avoid "tripping" the immune response in recipients, according to new research from North Carolina State University. The work could simplify the stem cell treatment process for ligament and tendon injuries in horses, and may also have implications for human stem cell therapies.
Floating sea macro-litter is a threat to the conservation of marine ecosystems worldwide. The largest density of floating litter is in the great ocean gyres -systems of circular currents that spin and catch litter- but the polluting waste is abundant in coastal waters and semi closed seas such as the Mediterranean.
A new study led by the University of Kent's Durrell Institute of Conservation and Ecology (DICE) has found that elephants living around the world-famous Masai Mara National Reserve, Kenya, are crop-raiding closer to the protected area, more frequently and throughout the year but are causing less damage when doing so.

CHAMPAIGN, Ill. -- Chemical manufacturers frequently use toxic solvents such as alcohols and benzene to make products like pharmaceuticals and plastics. Researchers are examining a previously overlooked and misunderstood phenomenon in the chemical reactions used to make these products. This discovery brings a new fundamental understanding of catalytic chemistry and a steppingstone to practical applications that could someday make chemical manufacturing less wasteful and more environmentally sound.
The rapid development of silicon-based transistors leads to its integration getting closer to the limit of Moore's law. Graphene is expected to become the next generation of mainstream chip materials due to its ultra-high carrier mobility. However, it is difficult to obtain a high on/off current ratio for intrinsic graphene-based transistor owing to the absence of bandgap. Graphene nanoribbons, which possess a tunable bandgap and unique optoelectrical properties, have attracted extensive attention and exploration.
DETROIT - Wayne State University School of Medicine researchers have reported that zinc supplements for men and women attempting to conceive either naturally or through assisted reproduction during the COVID-19 pandemic may prevent mitochondrial damage in young egg and sperm cells, as well as enhance immunity against the virus.
Anyone who's been to a concert knows that something magical happens between the performers and their instruments. It transforms music from being just "notes on a page" to a satisfying experience.
WASHINGTON--The start of California's annual rainy season has been pushed back from November to December, prolonging the state's increasingly destructive wildfire season by nearly a month, according to new research. The study cannot confirm the shift is connected to climate change, but the results are consistent with climate models that predict drier autumns for California in a warming climate, according to the authors.
ANN ARBOR, Mich. - The suicide rate among American adolescents has rose drastically over the last decade, but many at-risk youths aren't receiving the mental health services they need.
In fact, one of the greatest challenges is identifying the young people who need the most help.
People with severe mental disorders have a significantly increased risk of dying from COVID-19. This has been shown in a new study from Umeå University and Karolinska Institutet in Sweden. Among the elderly, the proportion of deaths due to COVID-19 was almost fourfold for those with severe mental disorders compared to non-mentally ill people in the same age.
Humans continuously observe and evaluate interactions between third parties to decide with whom to interact in the future. But it is difficult to measure what information animals gain when they eavesdrop on vocal interactions between conspecifics: If they do understand such conversations, they do not necessarily exhibit behavioral expressions that can be easily observed. To overcome this hurdle, anthropologists from the University of Zurich created a study combining call simulations, thermography methods and behavioral preference measures.
Consider for a moment a tree swaying in the wind. How long does it take for the movement of a twig to reach the trunk of the tree? How is this motion actually transmitted through the tree? Researchers at the University of Freiburg are transferring this kind of question to the analysis of proteins - which are the molecular machinery of cells. A team of researchers lead by Prof. Dr. Thorsten Hugel of the Institute of Physical Chemistry, and Dr. Steffen Wolf and Prof. Dr.
Researchers have found new evidence that global warming is affecting the size of commercial fish species, documenting for the first time that juvenile fish are getting bigger, as well as confirming that adult fish are getting smaller as sea temperatures rise. The findings are published in the British Ecological Society's Journal of Applied Ecology.
The world's largest bird, the ostrich, has problems reproducing when the temperature deviates by 5 degrees or more from the ideal temperature of 20 °C. The research, from Lund University in Sweden, is published in Nature Communications.
The results show that the females lay up to 40 percent fewer eggs if the temperature has fluctuated in the days before laying eggs. Both male and female production of gametes is also negatively affected.
