Scientists have created a comprehensive map of brain genes that regulate brain development, linking specific genes to specific brain locations. The Mahoney Transcription Factor Atlas will aid researchers in studying brain tumors and other disorders.
Researchers at Dana-Farber Cancer Institute found that the loss of hair color is caused by the gradual dying off of adult stem cells, which become depleted and make errors. This discovery may lead to a better understanding of the underlying mechanism of graying and potentially inform treatment for malignant melanoma.
A study found that people use different strategies to complete a jigsaw puzzle, which can increase competition and conflict when collaborating with others. The researchers identified two main approaches: 'border obsessives' who focus on completing the border first, and 'opportunistic' puzzlers who take a more creative approach.
Researchers found that male songbirds who shed their feathers too late may have duller, less colorful plumage, which could disadvantage them in attracting mates. The study, published in Science, used stable hydrogen isotopes and spectrometry to analyze feather color and carotenoid concentrations.
A new driving regulation in Japan allows people with epilepsy to obtain a driver's license after a seizure-free period of two years. The survey results highlighted the need for cooperation between authorities and the Japanese Epilepsy Society to further amend regulations and educate the public, patients, and professionals.
Research found lesions on sperm whale bones increase with age and size, suggesting chronic decompression damage. Nitrogen gas bubbles from sonar or seismic survey guns may cause acute problems in whales.
Researchers discovered a link between brain activity and abnormal heart rhythms during stressful events, particularly in people with pre-existing heart disease. The study suggests that uneven brain signals can disrupt heart function, leading to potentially fatal arrhythmias.
The UGA/Penn team aims to develop a single-access point for genomic and related information about Apicomplexa parasites, enabling accelerated vaccine, diagnostic, and therapeutic development. The database will link existing databases for Plasmodium species, Toxoplasma gondii, and Cryptosporidum parvum.
Enterococcus faecalis uses a Sonar-like system to detect human blood cells and produce a toxin in response, providing a potential mechanism for developing new antibiotic treatments. This discovery could also be adapted to help the aging population cope with vision loss.
Researchers found that beta-arrestin2 activates the hedgehog signaling pathway, which can lead to cancerous tumors. The study suggests potential new drugs to block tumor growth by disrupting beta-arrestin2's function.
Research suggests that changes in gut microflora can intensify immune reactions to common allergens, increasing the risk of chronic allergies or asthma. A mouse model study found that antibiotic treatment led to an overzealous allergic response in the lung.
Researchers found that modern snails began edge-drilling their prey when competing for food with others, but returned to slow wall drilling when separated. This suggests that the severe extinction event ended high competition levels in the ocean, which have not fully recovered since.
