With marijuana use during pregnancy on the rise, a new study led by the Colorado School of Public Health shows that prenatal cannabis use was associated with a 50 percent increased likelihood of low birth weight, setting the stage for serious future health problems including infection and time spent in neonatal intensive care units.
People may be deteriorating into dementia later in life and living with it for a shorter period of time, a new study suggests.
Many soldiers returning from combat bear visible scars, or even lost limbs, caused by blasts from improvised explosive devices, or IEDs. However, some servicemen also return with debilitating hidden injuries -- the loss of all or part of their genitals. Now, the Johns Hopkins reconstructive surgery team that performed the country's first bilateral arm transplant in a wounded warrior has successfully performed the first total penis and scrotum transplant in the world.
Nature has inspired a coating for synthetic leather that repels oil and water--and keeps the material from getting sticky in the heat.
A team led by Columbia University Biomedical Engineering Professor Gordana Vunjak-Novakovic has designed a creative new approach to help injured hearts regenerate by applying extracellular vesicles secreted by cardiomyocytes rather than implanting the cells. The study shows that the cardiomyocytes derived from human pluripotent stem cells (derived in turn from a small sample of blood) could be a powerful, untapped source of therapeutic microvesicles that could lead to safe and effective treatments of damaged hearts.
Study looked at 46 women across two different age ranges, 60-74 and 75-90, to learn how physical activity affects frailty differently in the two groups.
The stigma of weight and internalized feelings relating to it were found in a Drexel University study to be associated with healthcare avoidance in women with higher body weights.
A new poll shows most Europeans think life is generally fair, but have concerns over justice, political decisions and income inequality.
In a new study published April 23 in the journal Nature Physics, Yale researchers 'pitch' a qubit -- a tiny bit of quantum data -- from one physical point in a microwave cavity to a separate point in a different cavity. It is the first time an end-to-end quantum transmission has been done on demand and represents the first of two Yale experiments involving 'pitch-and-catch' technologies that will be published this year.
A machine learning method called 'deep learning,' which has been widely used in face recognition and other image- and speech-recognition applications, has shown promise in helping astronomers analyze images of galaxies and understand how they form and evolve. In a new study, researchers used computer simulations of galaxy formation to train a deep learning algorithm, which then proved surprisingly good at analyzing images of galaxies from the Hubble Space Telescope.
Opponents of gun control have frequently pointed to high rates of gun violence in cities such as Chicago to argue that strong state gun control laws are not effective.But guns used in states with stricter gun laws typically flow from states with weaker laws, according to a new study from Boston University School of Public Health (BUSPH) researchers.
In an advance that makes a more flexible, inexpensive type of solar cell commercially viable, University of Michigan researchers have demonstrated organic solar cells that can achieve 15 percent efficiency.
A drug that failed to effectively strike larger targets in lung cancer hits a bulls-eye on the smaller target presented by a previously untreatable form of the disease, researchers at the University of Texas MD Anderson Cancer Center report in Nature Medicine.
Europe's ash dieback epidemic could well have been caused by just one or two mushroom-like fruiting bodies of a fungal pathogen from Asia, according to a comprehensive genome sequencing effort published in Nature Ecology & Evolution. This leaves even the most resistant ash trees at threat from the introduction of just one more spore from East Asia.
A new international study involving the Australian National University and the University of Sydney has found that galaxies grow bigger and puffier as they age.
Researchers at Oxford University have shown that it is possible to identify genetic catalysts that accelerate the evolution of antibiotic resistance in bacteria -- and that this knowledge could be used to design treatments to stifle the development of resistance.
Hydrogen sulfide, the gas that gives rotten eggs their distinctive odor, permeates the upper atmosphere of the planet Uranus -- as has been long debated, but never definitively proven. Based on sensitive spectroscopic observations with the Gemini North telescope, astronomers uncovered the noxious gas swirling high in the giant planet's cloud tops. This result resolves a stubborn, long-standing mystery of one of our neighbors in space.
Warmer springs create a 'mismatch' where hungry chicks hatch too late to feast on abundant caterpillars, new research shows.
Using advanced imaging technology, researchers observe new patterns of molecular organization as connections between neurons strengthen during learning.
An international team, led by Berkeley Lab scientists, has demonstrated a breakthrough in the design and function of nanoparticles that could make solar panels more efficient by converting light usually missed by solar cells into usable energy.
