Extreme global warming 252 million years ago caused a severe mass extinction of life on Earth. It took life up to 9 million years to recover. New study finds clues in the Arctic as to why this recovery took so long.
Increasing ocean acidification could double the mortality of newly hatched cod larvae. Researchers quantified mortality rates of cod at conditions which the fish may experience towards the end of the century. They integrated results of two experiments in model calculations on stock dynamics. Show More Summary
Tissue manufacturers are now much closer to producing the perfect paper, thanks to new research.
Plants are adapting to increasing atmospheric CO2 according to a new study.The research provides insight into the long-term impacts of rising CO2 and the implications for global food security and nature conservation.
Scientists have found Ebola's Achilles' heel: a new kind of chemical compound can block the protein Ebola uses to break out of cells and infect new cells. The compounds could potentially be used to treat the disease after infection.
Childhood brain injuries, including concussions, are associated with an increased risk of subsequent mental illness, poor school attainment and premature death, according to a new study.
Nutritional stress is a normal part of life; going hungry on a short-term basis generally does not impair important functions. The brain coordinates the response to nutritional stress but how it does this was, until now, not well understood. Show More Summary
Targeting certain donor cells lowered the risk of organ rejection in mice that underwent kidney and heart transplants. Results of this new study could lead to new ways of preventing or treating organ transplant rejection in humans.
The Caribbean islands form a natural laboratory for the study of evolution due to their unique biological and geological features. There has been heated discussion since the early 20th century on how species appeared on the islands. The Cuban solenodon is a small, rare, endangered animal, belonging to the mammalian order Eulipotyphla. Show More Summary
Understanding what counts as an addiction, and what can be done to address it is the work of researchers across many disciplines. But what tools are used to ‘measure’ addiction, and are these capable of legitimising an addiction or improving our knowledge of it?
Scientists have discovered the cause of the recent run of miserable wet summers as they begin to unravel the mysteries of the Atlantic jet stream.
Checked baggage fees have actually improved the departure performance of US airlines in addition to boosting revenue, new research has found.
An African desert-dwelling male bird favors his biological sons and alienates his stepsons, suggests new research. The species is the southern pied babbler, a black and white bird found in Botswana, Namibia, South Africa and Zimbabwe. Show More Summary
In the first large-scale and comprehensive study on the impacts of transporting honey bees to pollinate various crops, research shows that travel can adversely affect bee health and lifespan. Some of these negative impacts may be reduced...Show More Summary
Seagrass seed is killed by waterborne fungi that are related to the well-known potato blight, biologists have discovered. These fungi, which have not previously been found in seawater, hinder seed germination and thus prevent the restoration of seagrass.
Behavioral economists argue that the best way to address the problems caused by health plan complexity is to simplify and standardize the plans, a new report outlines.
Female triathletes are at a higher risk for several health issues, including pelvic floor disorders, new research indicates. Researchers conducted an internet survey of 311 self-identified female triathletes. Results showed a significant prevalence of pelvic floor disorders, with urinary incontinences (37.4 percent) and anal incontinence (28.0 percent) being the most common.
Standing desks lower the BMI trajectory in elementary-aged children over a two-year span--by an average of 5.24 percentile points, a landmark study has found.
As we've discussed before, ice-cream headache (a.k.a. "brain freeze") is a real phenomenon, and scientists are actively studying it. But before they can understand in detail the physiological events surrounding brain freeze, they must first have a robust way of inducing it. Show More Summary
