The rhythm of life is driven by the cycles of day and night, and most organisms carry in their cells a common, (roughly) 24-hour beat. In animals, this rhythm emerges from the suprachiasmatic nucleus in the hypothalamus. Take it out of the brain and keep it alive in a lab dish and this "brain clock" will keep on ticking for days. A new study reveals that the brain clock itself is driven, in part, by metabolism.
Some children, depending on other stressors, may have a harder time recovering from natural disasters.
Researchers have created an ultra-sensitive biosensor capable of identifying the smallest single virus particles in solution, an advance that may revolutionize early disease detection in a point-of-care setting and shrink test result wait times from weeks to minutes.
Genetic investigation of a Malaysian tribe may tell scientists why East Asians have light skin but lower skin cancer rates than Europeans, according to a team of international researchers. Understanding the differences could lead to a better way to protect people from skin cancer.
New research holds promise for the improved prevention and treatment of bacterial infections and the life-threatening complications of chronic inflammation that can result from them.
Cases of one of the world's deadliest diseases -- tuberculosis -- are rising at an alarming rate, despite widespread vaccination. Reasons for the ineffectiveness of the vaccine, especially in regions where this infectious disease is endemic, as well as arguments for replacing the existing vaccine with novel synthetic vaccines, are now being presented.
The New England Banksia is largely restricted to the eastern edge of the New England Tableland, and is common in places along Waterfall Way. Researchers have raised this flowering plant, until now classified as a variety of the Hairpin, to the taxonomic level of a distinct species.
A recently discovered compound from the aminopyridine class not only has the potential to become part of a single-dose cure for all strains of malaria, but might also be able to block transmission of the parasite from person to person, according to a new research.
Drastic climate changes brought on by severe storms can spur allergy and asthma symptoms for sufferers across the country.
Scientists have devised a new technique for examining the binding kinetics of membrane proteins.
Scientists have completed the genome sequence and analysis of a diploid cotton -- Gossypium raimondii.
(Phys.org)—Proteins adorning the surfaces of human cells perform an array of essential functions, including cell signaling, communication and the transport of vital substances into and out of cells. They are critical targets for drug delivery and many proteins are now being identified as disease biomarkers – early warning beacons announcing the pre-symptomatic presence of cancers and other diseases.
