Domino-like crystallization of glass

Eurekalert - May 12 2021 - 00:05
Researchers from the Institute of Industrial Science, The University of Tokyo, Fudan University, and Peking University have revealed the thermodynamics and kinetics that facilitate crystal growth in deeply supercooled liquids and glasses. Their insights will help people exploit this atypical crystal growth behavior to enhance glass stability and crystal quality for applications.

Evaluation of the diagnostic criteria for anti-NMDA receptor encephalitis in children

Eurekalert - May 12 2021 - 00:05
We retrospectively reviewed clinical information of pediatric patients whose CSF was analyzed for NMDAR antibodies, and evaluated the 2016 diagnostic criteria for anti-NMDA receptor encephalitis. The criteria showed high sensitivity but low positive predictive value in our cohort. However, majority of the false positive cases were associated with a neuroimmunological disease. Collectively, physicians should start immunomodulatory therapy in the criteria-positive cases, but continue differential diagnosis, focusing especially on other forms of encephalitis.

New experimental drug cagrilintide (AM833), when combined with emaglutide, shows potential for treatment of obesity (The Lancet)

Eurekalert - May 12 2021 - 00:05
An early study of a new experimental drug to treat obesity known as cagrilintide shows that, when combined with semaglutide 2.4 mg, the combination leads to more weight loss than semaglutide 2.4 mg alone and is well tolerated. This phase 1 study, which was recently published in The Lancet will be presented at this year's European Congress on Obesity.

Study finds that obesity drug semaglutide supresses appetite, food cravings and energy intake

Eurekalert - May 12 2021 - 00:05
New research presented at this year's European Congress on Obesity (held online, 10-13 May) shows that the obesity drug semaglutide reduces appetite, food cravings and energy intake in people given a meal where they could eat as much as they liked. The study is by Dr Dorthe Skovgaard, Novo Nordisk A/S (the manufacturer of the drug), Søborg, Denmark, and colleagues.

Previously unknown letter reveals Einstein's thinking on bees, birds and physics

Eurekalert - May 12 2021 - 00:05
Could bees and birds help us understand the principles of physics? Albert Einstein thought so, according to a long-lost letter that reveals he predicted a link between physics and biology seven decades before the evidence emerged.

Research reveals ancient people had more diverse gut microorganisms

Eurekalert - May 12 2021 - 00:05
Meradeth Snow, a University of Montana researcher and co-chair of UM's Department of Anthropology, was part of an international team that used human "paleofeces" to discover that ancient people had far different microorganisms living in their guts than we do in modern times.

Measuring brain blood flow and activity with light

Eurekalert - May 12 2021 - 00:05
A new, noninvasive method for measuring brain blood flow with light has been developed by biomedical engineers and neurologists at UC Davis and used to detect brain activation. The new method, functional interferometric diffusing wave spectroscopy, or fiDWS, promises to be cheaper than existing technology and could be used for assessing brain injuries, or in neuroscience research.

A PROMPT, low-cost platform speeds up gonorrhea testing and spots antibiotic resistance

Eurekalert - May 12 2021 - 00:05
A portable, rapid testing platform can detect gonorrhea infections in patient samples in under 15 minutes, far faster than standard-of-care tests that can take hours or days.

UNH research estimates 1.4 million children have yearly violence-related medical visits

Eurekalert - May 12 2021 - 00:05
A national report from the University of New Hampshire shows close to one and a half million children each year visit a doctor, emergency room or medical facility as a result of an assault, abuse, crime or other form of violence. This is four times higher than previous estimates based only on data from U.S. emergency rooms for violence-related treatment.

Backyard chickens, rabbits, soybeans can meet household protein demand

Eurekalert - May 12 2021 - 00:05
In 2020, stores sold out of garden seed, coops and rabbit cages. Meat shortages led many to wonder what to eat for protein when supply chains are disrupted and some people turned to gathering eggs, raising animals and growing their own food. A team from Michigan Tech and the University of Alaska assessed backyard protein sources: They looked at how a typical household with a typical backyard can raise chickens, rabbits or soybeans to meet its protein needs.

COVID-19 is not influenza, but it offers lessons on beating it, say Concordia researchers

Eurekalert - May 12 2021 - 00:05
Two Concordia researchers and their colleagues study the 2020 influenza figures from Canada, the United States, Australia and Brazil and show there is a clear relationship between COVID-mitigation measures such as hand-washing, masking and social distancing and the spread of the annual flu. They write that these preventive measures all but eliminated the flu in countries where it can kill tens of thousands of people a year, even as cases of COVID-19 soared.

How the body builds a healthy relationship with 'good' gut bacteria

Eurekalert - May 12 2021 - 00:05
Research published in Nature reveals insights into how the body maintains balance with "good" gut bacteria that allows these microbes to flourish in the intestine but keeps them out of tissues and organs where they're not supposed to be.

A delicate balance: Learning new ways that gut microbes educate the immune system

Eurekalert - May 12 2021 - 00:05
An immune system that mistakes our good gut bacteria for an enemy can cause a dangerous type of inflammation in the intestines called colitis. An immune system that looks the other way while gut microbes spill past their assigned borders is equally dangerous. Understanding how the immune system learns to make a brokered peace with its microbial residents, called the microbiota, is therefore an important area of research.

Study finds ghost forest 'tree farts' contribute to greenhouse gas emissions

While standing dead trees in ghost forests did not release as much greenhouse gas emissions as the soils, they did increase GHG emissions of the overall ecosystem by about 25 percent.

UCLA scientists decode the 'language' of immune cells

Eurekalert - May 12 2021 - 00:05
UCLA scientists have identified 'words' immune cells use to call up immune defense genes -- an important step toward understanding their language. The scientists also discovered that in an autoimmune disease, Sjögren's syndrome, two of these words are used incorrectly, activating the wrong genes and triggering the disease. Senior author, UCLA Professor Alexander Hoffmann, compares decoding the language of immune cells to when archaeologists discovered the Rosetta stone and could begin to read Egyptian hieroglyphs.
