The risk of birth defects among twins may be higher among mums who haven't used fertility treatment -- which is known to increase the chances of a twin birth -- than among those who have used it, finds US research.
Between a third and half (43 percent) of the UK population -- roughly 28 million adults -- lives with chronic pain, finds an analysis of the available evidence.
A university degree is linked to a heightened risk of developing a brain tumor, suggests a large observational study. Gliomas, in particular, were more common among people who had studied at university for at least three years than they were among those who didn't go on to higher education, the data show.
Made-to-order nanocages open possibilities of shipping cargo into living cells, building small chemical reactors
Researchers have designed and produced a self-assembling protein shell shaped like an icosahedron -- similar to those that encapsulate viruses. The achievement may open new avenues for engineering cargo-containing nano-cages to package and deliver drugs and vaccines directly into cells, or building small reactors to catalyze biochemical reactions. The shell is also amenable to genetic fusion, such as the addition of fluorescent proteins.
In a small study looking at pain assessments in adults with sickle cell disease, researchers say overall, those treated long-term with opioids often fared worse in measures of pain, fatigue and curtailed daily activities than those not on long-term opioids.
Under growing pressure to report accurate findings as they interpret increasingly larger amounts of data, researchers are finding it more important than ever to follow sound statistical practices.
A new NOAA outlook shows that many coral reefs across around the world will likely be exposed to higher-than-normal sea temperatures for an unprecedented third year in a row, leading to increased bleaching - and with no signs of stopping. While the bleaching event is global, it will hit the US hard.
Scientists have identified agents for the separation of rare-earth metals that are potentially much less costly and better-performing than those currently used.
Children who often go hungry have a greater risk of developing impulse control problems and engaging in violence, according to new research.
Researchers have just the thing for information overload: image-processing technology that sees all and remembers only what it should. RedEye could allow computers to continuously see what their owners see.
A species of wasp that is a natural enemy of a wood-boring beetle that kills black locust trees has been rediscovered, more than 100 years after the last wasp of this species was found.
More than one in three atrial fibrillation (AF) patients at intermediate to high risk for stroke are treated with aspirin alone, despite previous data showing this therapy to be inferior to blood thinners, new research suggests.
Adolescents focus on rewards and are less able to learn to avoid punishment or consider the consequences of alternative actions, finds a new study. The study compared how adolescents and adults learn to make choices based on the available information.
Oceanic manta rays -- often thought to take epic migrations -- might actually be homebodies, according to a new study. A research team studied satellite-tracked manta rays to shed light on the lives of these mysterious ocean giants.
Scientists can now detect magnetic behavior at the atomic level with a new electron microscopy technique. The researchers took a counter intuitive approach by taking advantage of optical distortions that they typically try to eliminate.
Researchers have conducted the first ancient DNA investigation of the Himalayan arc, generating genomic data for eight individuals ranging in time from the earliest known human settlements to the establishment of the Tibetan Empire. The findings demonstrate that the genetic make-up of high-altitude Himalayan populations has remained remarkably stable despite cultural transitions and exposure to outside populations through trade.
China has an opportunity to massively increase its use of wind power -- if it properly integrates wind into its existing power system, according to a new study. The research forecasts that wind power could provide 26 percent of China's projected electricity demand by 2030, up from 3 percent in 2015.
New research aims to help educators quantify how the best students perform problem solving with the aid of instructional videos, a step toward learning how to better coach students in difficult engineering curricula.
Scientists are getting closer to directly observing how and why water is essential to life as we know it.
Tumors are composed of many subpopulations of cells. Some of these subpopulations of cancer cells can be predicted and do not develop randomly as previously thought, report investigators.
