New research from the University of California, Irvine, finds that drug withdrawal-induced anxiety and reinstatement of drug seeking behaviors are controlled by a single pathway in the brain and centered around dopamine cells.
Cognitive impairment as a result of severe COVID-19 is similar to that sustained between 50 and 70 years of age and is the equivalent to losing 10 IQ points, say a team of scientists from the University of Cambridge and Imperial College London.
Exercise supports the treatment of non-alcoholic fatty liver disease by impacting on several metabolic pathways in the body, a new study from the University of Eastern Finland shows.
Too many women are getting unnecessary mastectomies and other invasive procedures because of a knowledge gap about differences in cancer genes. A new study offers a path to closing the gap.

In the ultimate use of telemedicine, Stephan Moll, MD, worked with NASA to treat a U.S. astronaut’s blood clot during a mission on the International Space Station. That led to a study on how blood flows in zero gravity, and if astronauts are at greater risk of developing blood clots in space.
Cornell University researchers have identified a shift that occurs in canine coronavirus that may provide clues as to how it transmits from animals to humans.
Scientists have developed a groundbreaking AI-based algorithm for modeling the properties of materials at the atomic and molecular scale. It should greatly speed up materials discovery.
Elevated levels of an enzyme called PHGDH in the blood of older adults could be an early warning sign of Alzheimer’s disease. Research led by UC San Diego has consistently found high levels of PHGDH expression in brain tissue and blood samples of older adults with different stages of the disease.
In Physics of Fluids, researchers use principal component analysis along with fluid dynamics simulation models to show the crucial importance of proper fit for all types of masks and how face shape influences the most ideal fit. They modeled a moderate cough jet from a mouth of an adult male wearing a cloth mask over the nose and mouth with elastic bands wrapped around the ears and calculated the maximum volume flow rates through the front of mask and peripheral gaps at different material porosity levels.
When it comes to weight loss, the old adage it’s all in your head may be true. Scientists at Wake Forest University School of Medicine have shown that two specific networks in the brain can strongly influence how successful a person will be when trying to lose weight.
A new study published today in Animal Behaviour shows for the first time that brilliant iridescence and gloss found in some animals can have a protective function by working as a form of deceptive warning colouration, and that it is the key feature of iridescence, its changing colours, that is important for this effect.
A new study led by SMU paleontologist Anthony Fiorillo identifies the key role precipitation and temperature play in structuring vertebrate herbivore dinosaur populations in Alaska. The findings, which are published in the journal Geosciences, may also provide historical insights into the consequences of climate change.
A team of researchers led by R. Alexander Pyron, the Robert F. Griggs Associate Professor of Biology at the George Washington University, has discovered a new species of swamp-dwelling dusky salamander from the Gulf Coastal Plain of southeastern Mississippi and southwestern Alabama.
What do gunpowder, penicillin and Teflon all have in common? They were inventions that took the world by storm, but they were all created by complete accident.
Per- and polyfluoroalkyl substances (PFAS) and phthalates (two types of endocrine-disrupting chemicals) may be associated with lower bone mineral density in male teens, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology and Metabolism.
Tranexamic acid (TXA) – a medication given to reduce the risk of bleeding during some orthopaedic surgical procedures – can be safely used in patients with intertrochanteric (IT) hip fractures who are at high risk of blood clot-related complications, reports a study in The Journal of Bone & Joint Surgery. The journal is published in the Lippincott portfolio in partnership with Wolters Kluwer.
Agricultural efforts in downstream countries in Central Asia would be significantly boosted with a “dual water and energy storage scheme”, which also paves the way for high shares of renewable energy generation in the region.
