Researchers analyzed fish bones excavated from the Early Neolithic Jiahu site in Henan Province, China. By comparing the body-length distributions and species-composition ratios of the bones with findings from East Asian sites with present aquaculture, the researchers provide evidence of managed carp aquaculture at Jiahu dating back to 6200-5700 BC.
Read morePhysicists have identified how to distinguish between true and 'fake' Majorana states in one of the most commonly used experimental setups, by means of supercurrent measurements. This theoretical study is a crucial step for advancing the field of topological superconductors and applications of Majorana states for robust quantum computers. New experiments testing this approach are expected next.
Read moreScientists describe a previously unknown disorder of the immune system: in a distinct subset of immune cells from patients with primary immunodeficiency, cellular respiration is significantly increased. This cellular metabolic overactivity leads to inflammation.
Read moreA restricted-sleep schedule built to resemble an American work week made study participants feel less full after a fatty meal and altered their lipid metabolism. One night of recovery sleep helped, but didn't completely erase the effects of sleep restriction.
Read moreNew study finds adolescent sleep timing preferences and patterns should be considered risk factors for obesity and cardiometabolic health.
Read moreA new way to convert carbon dioxide into the building block for sustainable liquid fuels was very efficient in tests and did not have the reaction that destroys the conventional device.
Read moreWhile the medical community agrees immune cells inside a tumor leads to improved health outcome, for a subset of colorectal cancer patients, having too much of a good thing is a strong predictor of disease recurrence and reduced chances of survival. Scientists identify patients who could benefit from immunotherapy. This is the first report of immune infiltrated tumors with poor health outcomes and is counter to the standard belief in the field.
Read moreSemiconductors — and our mastery of them — have enabled us to develop the technology that underpins our modern society. These devices are responsible for a wide range of electronics, including circuit boards, computer chips and sensors.
Read moreNew research shows just how important positive childhood experiences are for long-term health, especially for those who experience significant adversity as a child. Studies over the past 20 years have found a correlation between adverse childhood events (such as death or divorce) and worse health outcomes later in life. A new study discovers that positive childhood experiences, like having good neighbors, or a teacher you trust, have the potential to negate harmful health effects caused by adverse childhood experiences.
Read moreA research team has developed a novel sample holder that considerably facilitates the preparation of protein crystals for structural analysis. New research shows how proteins in solution can be crystallized directly onto the new sample holders themselves, then analyzedd using the MX beamlines at BESSY II. A patent has already been granted and a manufacturer found.
