An international research group studying 520,000 people from around the world has identified 22 new genetic risk factors for stroke, tripling the number of gene regions known to affect stroke risk. These results provide new clues on stroke mechanisms and could help scientists identify drug targets for treatment. The work is the largest genetic study on stroke ever.
Observations by NASA's Hubble Space Telescope of galaxy NGC 1052-DF2 have turned up an oddity that sets it apart from most other galaxies, even the diffuse-looking ones. It contains little, if any, dark matter, an invisible substance that makes up the bulk of our universe.
In response to repeated calls for an integrated emergency care system in the U.S., the University of Pittsburgh rose to the challenge and divided the nation into hundreds of referral regions that describe how patients access advanced care, in a way that respects geopolitical borders.
Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a way to print 3-D structures composed entirely of liquids. Using a modified 3-D printer, they injected threads of water into silicone oil — sculpting tubes made of one liquid within another liquid.
Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have published a new study that identifies the process by which holes get trapped in nanoparticles made of zinc oxide, a material of potential interest for solar applications because it absorbs ultraviolet light.
High tide floods, or so-called “nuisance flooding,” that happen along shore roadways during seasonal high tides or minor wind events are occurring far more frequently than ever before. Researchers at the University of New Hampshire have found that in the past 20 years roads along the East Coast have experienced a 90 percent increase in flooding – often making the roads in these communities impassable, causing delays, as well as stress, and impacting transportation of goods and services.
First demonstration of high-pressure metastability mapping with ultrafast X-ray diffraction shows objects aren’t as large as previously thought.
Researchers at the University of Vienna and the Austrian Academy of Sciences develop a new theoretical framework to describe how causal structures in quantum mechanics transform. They analyse under which conditions quantum mechanics allows the causal structure of the world to become "fuzzy". In this case, a fixed order of events is not possible.
New research published in the current issue of the Journal of Personal and Social Relationships shows that the emotional processing of children whose parent argue frequently can be adversely affected, with potentially long term adverse consequences.

Using data from male inmates in 23 maximum-security prisons, researchers looked at factors related to fear of rape and likelihood of requesting mental health treatment while incarcerated. They focused on those at most risk of being victimized: gay or bisexual inmates and those with a history of childhood sexual abuse.
In the wake of the 2010 Deepwater Horizon oil spill, University of Florida researchers surveyed people in Gulf coast communities, representing 930 household members, to learn patterns of seafood consumption. A key element needed for this effort was a tool to help survey participants accurately report how much Gulf seafood they actually eat. Anne Mathews, a UF/IFAS assistant professor of food science and human nutrition, led research that examined how accurately people could report their seafood intake, based on photographs of different portion sizes of cooked seafood.
Researchers at Lawrence Berkeley National Laboratory and UC Berkeley decided to analyze the cost, energy, and environmental implications of a fleet of self-driving electric vehicles operating in Manhattan. They found that shared automated electric vehicles, or SAEVs, could get the job done at a lower cost – by an order of magnitude – than present-day taxis while also reducing greenhouse gas emissions and energy consumption.

After years of public health efforts, health care at the Los Angeles County Jail has significantly improved, and the facility now typically provides full access to treatment for inmates who have HIV — including medications that keep their disease in check. When they are released, however, many former inmates stop making regular visits to a doctor and taking the medication they need, which puts their own health at risk and increases the chance they will transmit the virus to others.
Narcissists aren’t necessarily on the hunt for partners who are already in a relationship – but that doesn’t appear to stand in their way, either, new research suggests.
New strategies in antiretroviral therapy, however, are charting a course for reducing dosages with longer-acting medications that have fewer side effects.

Their study appears in the March 23 issue of the Journal of Biological Chemistry.
A hot, metallic, Earth-sized planet with a density similar to Mercury - situated 260 million light years away - has been detected and characterised by a global team of astronomers, including the University of Warwick.Named K2-229b, the planet is almost 20% larger than Earth but has a mass which is over two-and-a-half times greater –and reaches a dayside temperature of over 2000°C (2330 Kelvin).
Wistar researchers have found rationale for repurposing a class of antitumor compounds called HDAC inhibitors as a new therapeutic option for ovarian cancer with mutations in the ARID1A gene.
Doctors recommend against taking antibiotics for viral infections because they don't work – antibiotics don't kill viruses – and do promote antibiotic resistance. A new study from Washington University School of Medicine in St. Louis suggests another reason to avoid the pills: Taking antibiotics increases susceptibility to subsequent viral infection, at least in mice.
An international team of researchers, led by Dr. Asier Gomez-Olivencia of the University of the Basque Country (UPV/EHU) and including Binghamton University anthropologist Rolf Quam, has provided new insights on one of the most famous Neandertal skeletons, discovered over 100 years ago: La Ferrassie 1.
Fiber-optic cables package everything from financial data to cat videos into light, but when the signal arrives at your local data center, it runs into a silicon bottleneck. Instead of light, computers run on electrons moving through silicon-based chips, which are less efficient than photonics. To break through, scientists have been developing lasers that work on silicon. In this week’s APL Photonics, researchers write that the future of silicon-based lasers may be in quantum dots.
Using his own version of Harry Potter’s cloak of invisibility, Rutgers professor Andrew Norris can help make underwater objects appear invisible. Norris, a distinguished professor in the Department of Mechanical and Aerospace Engineering at Rutgers University–New Brunswick, is developing honeycomb-like metallic structures that reroute sound waves to create the impression that both the cloak and anything beneath it are not there. Rutgers Today asked Norris to discuss his pioneering research, which could lead to improved acoustic technology, including better imaging under water, and biomedical applications, such as better imaging of tissue.
A Kansas State University researcher is studying the risk of African swine fever virus in feed and developing ways to prevent the spread of the disease to the U.S.
