For the first time since 1914, a new species of the Japanese lily known as sukashiyuri has been identified. A research team analyzed the morphology and DNA of these lilies and has revised the conventional classification from four taxonomic groups to eight.
Researchers have identified a novel Heat Shock Factor (HSF), designated as HSF5, which plays a crucial role in the completion of meiosis and the activation of genes essential for sperm formation. This discovery provides valuable insights into underlying causes of spermatogenic failure, the major contributor to male infertility. Furthermore, unlike other typical Heat Shock Factors, which primarily regulate gene expression in response to stress, such as heat shock, HSF5 plays a specific role in male germ production during meiosis under non-stress conditions.
A simple blood test could allow doctors to determine whether a person may be at higher risk for stroke or cognitive decline during their lifetime, according to a new study.
When adults became angry after remembering past experiences, the function of cells lining the blood vessels was negatively impaired, which may restrict blood flow, according to a new study. Previous research has found that this may increase the risk of heart disease and stroke. In this study, episodes of anxiety and sadness did not trigger the same change in functioning of the blood vessel lining.
A new computer model uses a better artificial intelligence process to measure snow and water availability more accurately across vast distances in the West, information that could someday be used to better predict water availability for farmers and others. The researchers predict water availability from areas in the West where snow amounts aren't being physically measured.
Conventional plant regeneration approaches by cell culture require the external application of plant growth regulators, including hormones. However, optimizing culture conditions can be laborious. Now, researchers have developed a novel plant regeneration system that omits the need for hormone application by genetically regulating the expression of genes that control plant cell differentiation. Their work holds significant potential in the development of genetically modified plants in a simpler and cost-effective manner.
The moon passed in front of the bright red star Antares on April 27, hiding it for roughly 40 minutes
The study suggests that the amount of sub-surface ice in the first couple of metres is about five to eight times larger than the one on the surface in both poles
The mission would be the first to try to return rock samples from Mars to Earth so scientists can analyze them for signs of past life.
Common household products containing nanoparticles -- grains of engineered material so miniscule they are invisible to the eye -- could be contributing to a new form of indoor air pollution, according to a new study.
In an effort to improve delivery of costly medical treatments, a team of researchers in electrical engineering has developed a stimulating method that could make the human body more receptive to certain gene therapies.
Carbon emissions associated with air travel to professional conferences make up a sizable fraction of the emissions produced by researchers in academia.
An intensive modelling study has found methane emissions from fossil fuels declined between 1990 and the 2000s and have been stable since, whereas microbes have been producing more methane of late
Complex Regional Pain Syndrome (CRPS) is a chronic and debilitating pain disorder, typically considered lifelong with limited treatment options. Now, groundbreaking research finds that early detection and effective treatment can lead to significant recovery within 18 months, offering hope to millions of people worldwide.
Researchers have unveiled evidence for ancient human resilience to climate change in the Eastern Mediterranean.
The inventors of a suite of tests that enable food packages to signal if their contents are contaminated are working to bring producers and regulators together to get their inventions into commercial products, with the goal of preventing illness and reducing food waste.
An undergraduate student turns her honor's thesis into a peer-reviewed publication on schizophrenia research.
Researchers have discovered that the enzyme cyclophilin A, which is produced in large amounts in hematopoietic stem cells, is key for these cells to retain their regenerative potential and avert the effects of aging via an unexpected mechanism.
As the world faces the loss of a staggering number of species of animals and plants to endangerment and extinction, one scientist has an urgent message: Chemists and pharmacists should be key players in species conservation efforts.
Evapotranspiration (ET) includes evaporation from soil and open water pools such as lakes, rivers, and ponds, as well as transpiration from plant leaves. The difference between precipitation and ET indicates the water balance available for societal needs, including agricultural and industrial production. However, measuring ET is challenging. A new study presents a computer model that uses artificial intelligence (AI) for ET prediction based on remote sensing estimates.
