You wait ages for a pterosaur and then four come along at once.
Hot on the heels of a recent paper discovering three new species of pterosaur, University of Portsmouth palaeobiologists have identified another new species - the first of its kind to be found on African soil.
Pterosaurs are the less well-known cousins of dinosaurs. They had adept flying ability - some as large as a fighter jet and others as small as a model aeroplane.
Since its beginnings, quantum mechanics hasn't ceased to amaze us with its peculiarity, so difficult to understand. Why does one particle seem to pass through two slits simultaneously? Why instead of specific predictions can we only talk about evolution of probabilities? According to theorists from universities in Warsaw and Oxford, the most important features of the quantum world may result from the special theory of relativity, which until now seemed to have little to do with quantum mechanics.
The risk for violent clashes increases after weather extremes such as droughts or floods hit people in vulnerable countries, an international team of scientists finds. Vulnerable countries are characterized by a large population, political exclusion of particular ethnic groups, and low development. The study combines global statistical analysis, observation data and regional case study assessments to yield new evidence for policy-makers.
Sustainable energy storage is in great demand. Researchers at Uppsala University have therefore developed an all-organic proton battery that can be charged in a matter of seconds. The battery can be charged and discharged over 500 times without any significant loss of capacity. Their work has been published in the scientific journal Angewandte Chemie.
Open biomass burning (OBB) has a significant impact on regional air quality, especially on the heavy haze pollution in Northeast China (NEC) in recent years. Recent research published in Atmospheric and Oceanic Science Letters provides scholars and decision-makers with a more comprehensive and long-term analysis of the spatiotemporal patterns of OBB in NEC.
Doctors need to pay particular attention to patients with endocrine disorders and diabetes mellitus in relation to COVID-19 infections, say leading endocrinologists.
In an editorial published in the Journal of Clinical Endocrinology & Metabolism, they say data from Wuhan province in China, where the pandemic started, has revealed that patients with diabetes mellitus were over-represented in the group of people who become severely ill and also among those who died.
Reasonably good evidence suggests that most diets result in similar modest weight loss and improvements in cardiovascular risk factors over a period of six months, compared with a usual diet, finds a study published by The BMJ today.
Weight reduction at the 12 month follow-up diminished, and improvements in cardiovascular risk factors largely disappeared, except in association with the Mediterranean diet, which saw a small but important reduction in 'bad' LDL cholesterol.
HOUSTON -- A one-year follow-up study led by The University of Texas MD Anderson Cancer Center revealed a majority of patients with mantle cell lymphoma resistant to prior therapies may benefit from treatment with CD19-targeting chimeric antigen receptor (CAR) T-cell therapy. Findings were published in the April 1 online issue of the New England Journal of Medicine.
MINNEAPOLIS - Depression is common in people with Parkinson's disease and contributes to faster physical and mental decline, but it is often overlooked and undertreated. Cognitive-behavioral therapy has shown promising results for treating depression in people with Parkinson's, yet many people don't have access to therapists who understand Parkinson's and can provide this evidence-based depression treatment.
People with Parkinson's disease who engage in cognitive behavioral therapy -- a form of psychotherapy that increases awareness of negative thinking and teaches coping skills -- are more likely to overcome depression and anxiety, according to a Rutgers study.
The study was published in the journal Neurology.
About 50 percent of people diagnosed with Parkinson's disease will experience depression, and up to 40 percent have an anxiety disorder.
Every spring, American robins migrate north from all over the U.S. and Mexico, flying up to 250 miles a day to reach their breeding grounds in Canada and Alaska. There, they spend the short summer in a mad rush to find a mate, build a nest, raise a family, and fatten up before the long haul back south.
In an effort to provide safer working environments for nuclear medicine professionals and their patients, clinics across five continents have shared their approaches to containing the spread of COVID-19 in a series of editorials, published ahead of print in The Journal of Nuclear Medicine. This compilation of strategies, experiences and precautions is intended to support nuclear medicine clinics as they make decisions regarding patient care.
Bethesda, Maryland (April 1, 2020) -- Today, the American Gastroenterological Association (AGA) published new COVID-19 recommendations in Gastroenterology, the official journal of the AGA: AGA Institute Rapid Recommendations for Gastrointestinal Procedures During the COVID-19 Pandemic.
In the fight against neurodegenerative diseases such as frontotemporal dementia, Alzheimer's and Chronic Traumatic Encephalopathy, the tau protein is a major culprit. Found abundantly in our brain cells, tau is normally a team player -- it maintains structure and stability within neurons, and it helps with transport of nutrients from one part of the cell to another.
Neolithic populations have long been credited with bringing about a revolution in farming practices across Europe. However, a new study suggests it was not until the Bronze Age several millennia later that human activity led to significant changes to the continent's landscape.
