The period of austerity politics from 2012 to 2018 was associated with steeper increases in frailty with age compared to pre-austerity between 2002 and 2010, according to a new study published February 7th in the open-access journal PLOS ONE by Carys Pugh of the University of Edinburgh, UK, and colleagues. Previous research has linked a stalling in life expectancy growth to austerity politics implemented in response to the 2008-2009 financial crisis. However, the mechanism through which public spending cuts are associated with decreased life expectancy ...

Tiny external structures in the wax coating of blueberries give them their blue colour, researchers at the University of Bristol can reveal. This applies to lots of fruits that are the same colour including damsons, sloes and juniper berries. In the study, published today in Science Advances, researchers show why blueberries are blue despite the dark red colour of the pigments in the fruit skin. Their blue colour is instead provided by a layer of wax that surrounds the fruit which is made up of miniature structures that scatter blue and UV light. This gives blueberries their blue appearance to humans and blue-UV to birds. The chromatic blue-UV reflectance ...

Researchers with McMaster University and Denmark-based pharmaceutical company ALK-Abello A/S have made a groundbreaking discovery: a new cell that remembers allergies.

The speed at which England’s oldest adults became frailer accelerated during the UK Government’s era of austerity politics, according to a new study.  Researchers say that the rate of frailty in people aged 85 and over in England increased 50 per cent faster per year between 2012 and 2018 compared with the preceding eight years.   The impact of frailty – a decline in a person’s mental and physical resilience to illness and injury – on the oldest in society must be considered should any new austerity measures be introduced, experts warn.    The study, led by researchers from the University of Edinburgh’s ...

Tea Maho and Robert R. Reisz University of Toronto Mississauga   Kilat, the largest living lizard at the Toronto Metro Zoo, like other members of his species (Varanus komodoensis), truly deserves to be called the Komodo Dragon! Its impressive size and the way it looks at you and tracks your every move makes you realize that it is an apex predator, not unlike a ferocious theropod dinosaur. So, it is not surprising when you look around at his enclosure to find that there are shed teeth sparkling on the ground, a common find when ...

CAMBRIDGE, MA – A tiny device built by scientists at MIT and the Singapore-MIT Alliance for Research and Technology could be used to improve the safety and effectiveness of cell therapy treatments for patients suffering from spinal cord injuries. In cell therapy, clinicians create what are known as induced pluripotent stem cells by reprogramming some skin or blood cells taken from a patient. To treat a spinal cord injury, they would coax these pluripotent stem cells to become progenitor cells, which are destined to differentiate into spinal cord cells. These progenitors are then transplanted back into ...

Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have shed important new light on what the early signs of battery failure look like. Their study — which relates to a condition called soft-shorts — provides the research community with valuable knowledge and methods to design better electric vehicle (EV) batteries. The Argonne team’s research focused on all-solid batteries with anodes (negative electrodes) ...

UNIVERSITY PARK, Pa. — Predicting the trajectory of neurodevelopmental and psychiatric disorders like autism or schizophrenia is difficult because they can be influenced by many different genetic and environmental factors. A new study, led by Penn State researchers, demonstrates that evaluating parents for their manifestation of traits of these disorders — and related diseases like depression and anxiety — may provide a more accurate method of predicting the prevalence, and potentially severity, of the disorders in affected children than screening for genetic variants alone. This is likely due, at least in part, to genetic variants the parents transmit to the ...

Birmingham, AL (February 7, 2024) – Today, a team of scientists is pleased to announce the discovery of a new fossil shark species from Alabama, USA.

New gene mapping technique reveals how genetic alterations in cells lining blood vessels contribute to coronary artery disease, with implications for diagnostic and treatment strategies. KEY TAKEAWAYS Researchers from the Brigham, the Broad Institute, and Stanford Medicine studied how "deleting" individual genes associated with coronary artery disease (CAD) impacted the expression of all the other genes in a cell to better understand underlying biology of CAD. The study focused on endothelial cells, which line blood vessels and are increasingly understood to influence CAD risk. The researchers highlighted a previously unrecognized role for the TLNRD1 gene ...

Next-generation electric vehicles could run on lithium metal batteries that go 500 to 700 miles on a single charge, twice the range of conventional lithium-ion batteries in EVs today. But lithium metal technology has serious drawbacks: The battery rapidly loses its capacity to store energy after relatively few cycles of charging and discharging – highly impractical for drivers who expect rechargeable electric cars to operate for years. Scientists have been testing a variety of new materials and techniques to improve the battery’s cycle life. Now, Stanford University researchers have discovered a low-cost solution: simply drain the battery and let it rest for several hours. ...

In a recent study of the brain’s waste drainage system, researchers from Washington University in St. Louis, collaborating with investigators at the National Institute of Neurological Disorders and Stroke (NINDS), a part of the National Institute of Health (NIH), discovered a direct connection between the brain and its tough protective covering, the dura mater. These links may allow waste fluid to leave the brain while also exposing the brain to immune cells and other signals coming from the dura. This challenges the conventional wisdom which has suggested that the brain is cut off from its ...

Chronic stress has far-reaching consequences for our bodies. For example, many stress-related psychiatric illnesses such as depression are associated with changes in the immune system. However, the underlying mechanisms of how these changes affect the brain are still largely unknown. Enzyme from immune cells in the blood affects nerves in the brain An international research team led by the University of Zurich (UZH), and the University Hospital of Psychiatry Zurich (PUK) and the Icahn School of Medicine at Mount Sinai, New York, has now uncovered a novel mechanism. “We were able to show that ...
