Skokie, IL - The International Society for Stem Cell Research (ISSCR), today released updated guidelines for stem cell research and its translation to medicine. The update reflects emerging advances including, stem cell-based embryo models, human embryo research, chimeras, organoids, and genome editing.
Communities benefit from sharing knowledge and experience among their members. Following a similar principle - called "swarm learning" - an international research team has trained artificial intelligence algorithms to detect blood cancer, lung diseases and COVID-19 in data stored in a decentralized fashion. This approach has advantage over conventional methods since it inherently provides privacy preservation technologies, which facilitates cross-site analysis of scientific data.
New research published in Nature provides a powerful yet surprisingly simple way to determine the number of visitors to any location in a city.
What The Study Did: Researchers conducted a review of studies examining the frequency and variety of persistent symptoms after COVID-19 infection.
Authors: Steven N. Goodman, M.D., M.H.S., Ph.D., of Stanford University in Stanford, California, is the corresponding author.

In the human gut, good bacteria make great neighbors.
A new Northwestern University study found that specific types of gut bacteria can protect other good bacteria from cancer treatments -- mitigating harmful, drug-induced changes to the gut microbiome. By metabolizing chemotherapy drugs, the protective bacteria could temper short- and long-term side effects of treatment.
Flowering plants (angiosperms) dominate most terrestrial ecosystems, providing the bulk of human food. However, their origin has been a mystery since the earliest days of evolutionary thought.
Angiosperm flowers are hugely diverse. The key to clarifying the origin of flowers and how angiosperms might be related to other kinds of plants is understanding the evolution of the parts of the flower, especially angiosperm seeds and the fruits in which the seeds develop.
LEXINGTON, Ky. (May 26, 2021) - Using novel imaging methods for studying brain metabolism, University of Kentucky researchers have identified the reservoir for a necessary sugar in the brain. Glycogen serves as a storage depot for the sugar glucose.
Berkeley -- The lifestyle of the horned passalus beetle, commonly known as the bessbug or betsy beetle, might seem downright disgusting to the average human: Not only does this shiny black beetle eat its own poop, known as frass, but it uses its feces to line the walls of its living space and to help build protective chambers around its developing young.
Gross as it may seem, a new study suggests that this beetle's frass habits are actually part of a clever strategy for protecting the insect's health -- and could help inform human medicine, too.
In a new study, scientists at The Hong Kong University of Science and Technology (HKUST) have revealed that most T cell epitopes known to be targeted upon natural infection are seemingly unaffected by current SARS-CoV-2 variants.
Rough night of sleep? Relying on caffeine to get you through the day isn't always the answer, says a new study from Michigan State University.
Researchers from MSU's Sleep and Learning Lab, led by psychology associate professor Kimberly Fenn, assessed how effective caffeine was in counteracting the negative effects of sleep deprivation on cognition. As it turns out, caffeine can only get you so far.
Reverse transcription-polymerase chain reaction (RT-PCR) has been the gold standard for diagnosis during the COVID-19 pandemic. However, the PCR portion of the test requires bulky, expensive machines and takes about an hour to complete, making it difficult to quickly diagnose someone at a testing site. Now, researchers reporting in ACS Nano have developed a plasmofluidic chip that can perform PCR in only about 8 minutes, which could speed diagnosis during current and future pandemics.
Adults with schizophrenia have an elevated risk of dying from suicide. Yet there's only limited understanding of when and why people with schizophrenia die of suicide --in part because research studies have looked at relatively small groups of patients.
Now a new study from Columbia that looked at a large population of adults diagnosed with schizophrenia has found the youngest group (18-34) had the highest suicide risk and those aged 65 and older had the lowest. By comparison, in the general U.S. population, younger adults have less risk and older age groups have greater risk.
When enjoying a chocolate bar, most people don't think about how the molecules within it are organized. But different arrangements of the fats in chocolate can influence its taste and texture. Now, researchers reporting in ACS' Crystal Growth & Design have found that the side of a chocolate bar facing the mold has a more orderly crystalline structure than the side facing air, knowledge that might help chocolatiers produce tastier confections, the researchers say.

The immune system's attempt to eliminate Salmonella bacteria from the gastrointestinal (GI) tract instead facilitates colonization of the intestinal tract and fecal shedding, according to National Institutes of Health scientists. The study, published in Cell Host & Microbe, was conducted by National Institute of Allergy and Infectious Diseases (NIAID) scientists at Rocky Mountain Laboratories in Hamilton, Montana.
MOSCOW, Idaho -- May 26, 2021 -- University of Idaho researchers partnered with other scientists from the United States and Australia to study the evolution of Tasmanian devils in response to a unique transmissible cancer.
