People who increased their daily servings of red meat over an eight-year period were more likely to die during the subsequent eight years compared to people who did not increase their red meat consumption, according to a new study led by researchers from Harvard T.H. Chan School of Public Health. The study also found that decreasing red meat and simultaneously increasing healthy alternative food choices over time was associated with lower mortality.
The study will appear online June 12, 2019 in BMJ.
Treatment with gabapentinoids - a group of drugs used for epilepsy, nerve pain and anxiety disorders - is associated with an increased risk of suicidal behaviour, unintentional overdose, injuries, and road traffic incidents, finds a study from Sweden published by The BMJ today.
Prescriptions have risen steeply in recent years, and gabapentinoids are among the top 15 drugs globally in terms of revenue.
The risks are strongest among 15 to 24 year-olds, prompting the researchers to suggest that treatment guidelines for young people should be reviewed.
Increasing red meat intake, particularly processed red meat, is associated with a heightened risk of death, suggests a large US study published in The BMJ today.
However, reducing red meat intake while increasing healthy protein sources, such as eggs and fish, whole grains and vegetables over time may lower the risk, the researchers say.
A familiar ingredient has been hiding in plain sight on the surface of Jupiter's moon Europa. Using a visible light spectral analysis, planetary scientists at Caltech and the Jet Propulsion Laboratory, which Caltech manages for NASA, have discovered that the yellow color visible on portions of the surface of Europa is actually sodium chloride, a compound known on Earth as table salt, which is also the principal component of sea salt.
A new study has found a high incidence of headaches in pediatric stroke survivors and identified a possible association between post-stroke headache and stroke recurrence. Headache developed in over a third of participating children, on average six months after the stroke. Fifteen percent of patients suffered another stroke, typically in the first six to 12 months after the initial stroke.
Cold Spring Harbor, NY -- Noroviruses are a leading cause of food-borne illness outbreaks, accounting for 58% of all outbreaks and cause 685 million cases worldwide each year. There is no effective therapeutic against them. Having knowledge of the intricate structure of the outer layer of noroviruses, the capsid, which allows the virus to attach to its human host, could help in vaccine development.
As planets form in the swirling gas and dust around young stars, there seems to be a sweet spot where most of the large, Jupiter-like gas giants congregate, centered around the orbit where Jupiter sits today in our own solar system.
The location of this sweet spot is between 3 and 10 times the distance Earth sits from our sun (3-10 astronomical units, or AU). Jupiter is 5.2 AU from our sun.
WASHINGTON -- A growing number of applications, including smartphone cameras, depend on microlenses to boost performance. A newly developed technology, called laser catapulting, could make it much easier and less expensive to fabricate these miniaturized lenses with customized properties, such as shape or focusing power.
Wikipedia is one of the most successful online communities in history, yet it struggles to attract and retain editors who are women -- another example of the gender gap online. In a recent University of Washington study, researchers interviewed women "Wikipedians" to examine the lack of female and non-binary editors in Wikipedia. The team identified a common theme: safety.
The flow of traffic through our nation's highways and byways is meticulously mapped and studied, but less is known about how materials in cells travel. Now, a team of researchers at the University of Missouri is challenging prior theories about how material leaves the inside of an E.coli cell. This discovery could have important implications for how we treat diseases.
A study of nearly 800,000 schoolchildren in New York City shows that Black, Hispanic, and Asian students live and go to school closer to both healthy and unhealthy food outlets than do White students. Brian Elbel of the New York University School of Medicine and colleagues present these findings in the open-access journal PLOS ONE.
Cannabis has been cultivated as an oil-seed and fibre crop for millennia in East Asia. Little is known, however, about the early use and eventual cultivation of the plant for its psychoactive and medicinal properties. Despite being one of the most widely used psychoactive drugs in the world today, there is little archaeological or historical evidence for the use of marijuana in the ancient world.
Scientists at The University of Queensland have upended biologists' century-old understanding of the evolutionary history of animals.
Using new technology to investigate how multi-celled animals developed, their findings revealed a surprising truth.
Professor Bernie Degnan said the results contradicted years of tradition.
"We've found that the first multicellular animals probably weren't like the modern-day sponge cells, but were more like a collection of convertible cells," Professor Degnan said.
Chemical analysis of several wooden braziers recently excavated from tombs in western China provides some of earliest evidence for ritual cannabis smoking, researchers report. The study suggests that smoking cannabis for ritual and religious activities was practiced in western China by at least 2500 years ago, and that the cannabis plants involved were producing high levels of psychoactive compounds, indicating that people were aware of and interacting with specific populations of the plant.
Intensifying climate change will increase the future risk of violent armed conflict within countries, according to a study published today in the journal Nature. Synthesizing views across experts, the study estimates climate has influenced between 3% and 20% of armed conflict risk over the last century and that the influence will likely increase dramatically.
