Finding new semi-conductor materials that emit light is essential for developing a wide range of electronic devices. But making artificial structures that emit light tailored to our specific needs is an even more attractive proposition. However, light emission in a semi-conductor only occurs when certain conditions are met. Today, researchers from the University of Geneva (UNIGE), Switzerland, in collaboration with the University of Manchester, have discovered an entire class of two-dimensional materials that are the thickness of one or a few atoms.
Scientists at Tokyo Institute of Technology designed a new type of controller for the robotic arm used in robotic surgery. Their controller combines the two distinct types of gripping used in commercially available robotic systems to leverage the advantages of both, reducing the efforts of the surgeon and providing good precision.
An international team of researchers carried out an experiment at HSE University demonstrating that knowledge of several languages can improve the performance of the human brain. In their study, they registered a correlation between participants' cognitive control and their proficiency in a second language.
The complications of measles can be many and varied, and more serious than people might realise, doctors have warned in the journal BMJ Case Reports after treating a series of adults with the infection.
Measles is a highly contagious respiratory viral infection, the symptoms of which include fever, cough, conjunctivitis, and an extensive rash all over the body.
Measles is entirely preventable as the vaccine used to immunise against it is safe and very effective.
Reducing animal product intake and following a primarily plant-based diet can decrease your risk of heart disease by minimizing the adverse effects of a gut-microbiome associated with increased risk of coronary heart disease, according to research published today in the Journal of the American College of Cardiology.
First study to map atomic structure of a key enzyme complex in paramyxoviruses, a family of RNA viruses
Enzyme is responsible for assembling RNA molecules, providing a target for new antiviral drugs
Although from a different family, coronavirus functions similarly
Researchers used cryo-EM, a revolutionary technique that gives a clear view of proteins
What The Study Did: Researchers looked at the net income of nonprofit hospitals in the U.S. and examined how their financial status was associated with the level of charity care they provided in 2017 for uninsured and insured patients.

Many insects, mosses and lichens in the UK are bucking the trend of biodiversity loss, according to a comprehensive analysis of over 5,000 species led by UCL and the UK Centre for Ecology & Hydrology (UKCEH).
The researchers say their findings on UK biodiversity between 1970 and 2015, published in Nature Ecology & Evolution, may provide evidence that efforts to improve air and water quality could be paying off.
The Arctic region has long been seen as one of the Earth's most remote frontiers. However, now the Arctic is changing fast and is important in global governance, geopolitics, and the global economy. Temperatures have warmed faster than the rest of the planet; sea ice is dramatically declined in summers; exploitation of oil and gas, new (sea) trade routes, tourism and other economic activities are expanding.
Scientists at the MDC have discovered stem cells responsible for the most common form of kidney cancer. The team of Walter Birchmeier has found a way to block the growth of these tumors in three models of the disease.
Not all cancer cells are equal. Tumors contain potent cancer stem cells which produce metastases and can regenerate the disease if they escape a treatment. This makes them vital targets for therapies - if scientists can isolate them and probe their weaknesses. But the cells are often so rare that for many types of cancer, they have yet to be found.
In experiments with human cells and mice, researchers at the Johns Hopkins Kimmel Cancer Center report evidence that combining the experimental cancer medication TAK228 (also called sapanisertib) with an existing anti-cancer drug called trametinib may be more effective than either drug alone in decreasing the growth of pediatric low-grade gliomas. These cancers are the most common childhood brain cancer, accounting for up to one-third of all cases.
What The Study Did: Patients with chronic life-limiting illnesses often have medical orders with treatment limitations in place regarding medical interventions and intensive care unit admissions near the end of their lives. This observational study included about 1,800 patients with such orders who were hospitalized within six months of their death to examine how often care was consistent with those orders.
EVANSTON, Ill. --- A wife-husband team will present both high-tech and low-tech solutions for improving water security at this year's American Association for the Advancement of Science (AAAS) annual meeting in Seattle on Sunday, Feb. 16. Northwestern University's Sera Young and Julius Lucks come from different ends of the science spectrum but meet in the middle to provide critical new information to approach this global issue.
For all the benefits in the expansion of the media landscape, we're still struggling with the spread of misinformation--and the damage is especially worrisome when it comes to information about science and health.
"Believing things that aren't true when it comes to health can be not just bad for us, but dangerous," said Dan Gillmor, co-founder of the News Co/Lab at Arizona State University's Walter Cronkite School of Journalism and Mass Communication. "Journalists have a special duty to avoid being fooled, and they can help us learn to sort out truth from falsehood ourselves."
Psychological tests are important instruments used in courts to aid legal decisions that profoundly affect people's lives. They can help determine anything from parental fitness for child custody, to the sanity or insanity of a person at the time of a crime, to eligibility for capital punishment.
While increasingly used in courts, new research shows the tests are not all scientifically valid, and once introduced into a case they are rarely challenged, according to Tess Neal, an assistant professor of psychology at Arizona State University.
