Opioid prescribing preferences and practices among surgical residents and faculty differ, according to a new study published in the journal Surgery.
Scientists at the University of Southampton have discovered that changes in Earth's orbit may have allowed complex life to emerge and thrive during the most hostile climate episode the planet has ever experienced.
East Hanover, NJ. July 7, 2021. A team of researchers identified nine meaningful reasons that prevent people with disabilities from seeking employment. Their findings provide a much-needed understanding of this population's motives for remaining unemployed, which can inform programs and policies that promote labor force participation of people with disabilities.
The principle that form follows function does not only apply to design and architecture. It also applies to biology. Every organism is a universe that lives thanks to the activities of tens of thousands of nanomachines, whose functions depend on their forms. Biologists say macromolecular complexes instead of nanomachines and structure instead of form, but the idea is the same: know the form and you will understand the function.
In 2019, Anaïs Llorens and Athina Tzovara -- one a current, the other a former University of California, Berkeley, postdoctoral scholar at the Helen Wills Neuroscience Institute (HWNI) -- were attending a scientific meeting and pleased that one session, on gender bias in academia, attracted nearly a full house. The problem: The audience of some 300 was almost all women.
Using an exceptionally preserved fossil from South Africa, a particle accelerator, and high-powered x-rays, an international team including a University of Minnesota researcher has discovered that not all dinosaurs breathed in the same way. The findings give scientists more insight into how a major group of dinosaurs, including well-known creatures like the triceratops and stegosaurus, evolved.
The study is published in eLife, a peer-reviewed open access scientific journal for the biomedical and life sciences.
Climate change is causing increased flooding and prolonged waterlogging in northern Europe, but also in many other parts of the world. This can damage meadow grasses, field crops or other plants - their leaves die, the roots rot.
The damage is caused by a lack of oxygen and the accumulation of acids. How do plants perceive this over-acidification, how do they react to it? This is what researchers from Würzburg, Jena (Germany) and Talca (Chile) describe in the journal Current Biology.
Abu Dhabi, UAE, July 5, 2021: NYU Abu Dhabi (NYUAD) researchers uncovered a code that sets the genome of the liver to account for the remarkable ability for this organ to regenerate. This finding offers new insight into how the specific genes that promote regeneration can be activated when part of the liver is removed. These findings have the potential to inform the development of a new form of regenerative medicine that could help non-regenerative organs regrow in mice and humans.
BUFFALO, N.Y. - How the media frame stories about science affects the public's perception about scientific accuracy and reliability, and one particular type of narrative can help ameliorate the harm to science's reputation sometimes caused by different journalistic approaches to scientific storytelling, according to a new study led by a University at Buffalo researcher.
A new national study published in Psychiatric Services finds that over a quarter of US adults with depression or anxiety symptoms reported needing mental health counseling but were not able to access it during the COVID-19 pandemic. Researchers analyzed data from nearly 70,000 adults surveyed in the US Census Household Pulse Survey in December 2020.
LAWRENCE -- A new paper from a lead author based at the University of Kansas finds wetlands constructed along waterways are the most cost-effective way to reduce nitrate and sediment loads in large streams and rivers. Rather than focusing on individual farms, the research suggests conservation efforts using wetlands should be implemented at the watershed scale.
A unique study of ancient diamonds has shown that the basic chemical composition of the Earth's atmosphere which makes it suitable for life's explosion of diversity was laid down at least 2.7 billion years ago. Volatile gases conserved in diamonds found in ancient rocks were present in similar proportions to those found in today's mantle, which in turn indicates that there has been no fundamental change in the proportions of volatiles in the atmosphere over the last few billion years.
Research published today has demonstrated the viability of 3D-printed tissue scaffolds that harmlessly degrade while promoting tissue regeneration following implantation.
The scaffolds showed highly promising tissue-healing performance, including the ability to support cell migration, the 'ingrowth' of tissues, and revascularisation (blood vessel growth).
Researchers at Uppsala University have discovered lymph node-like structures close to the tumour in brain cancer patients, where immune cells can be activated to attack the tumour. They also found that immunotherapy enhanced the formation of these structures in a mouse model. This discovery suggests new opportunities to regulate the anti-tumour response of the immune system.
Land plants - plants that live primarily in terrestrial habitats and form vegetation on earth - are anchored to the ground through their roots, and their performance depends on both the belowground soil conditions and the aboveground climate. Plants utilize sunlight to grow through the process of photosynthesis where light energy is converted to chemical energy in chloroplasts, the powerhouses of plant cells. Therefore, the amount and quality of light perceived by chloroplasts through light absorbing pigments, such as chlorophyll, is a defining factor in plant growth and health.
