People who seek novel and powerful sensations and are more prone to taking risks -- and who perceive bitter tastes tensely -- are more likely to prefer bitter, pale-ale-style beers and drink them more often, according to sensory researchers, who conducted a study that involved blind taste tests and personality assessments.
Researchers have added fresh evidence that early exposure to vaccine-, bacterial- or microbiota-derived antigens has a dramatic effect on the diversity of antibodies an adult mammal will have to fight future infections by pathogens. This antibody diversity is called the clonal repertoire -- basically different single cells with distinct antibody potential that can multiply into a large clone of cells, all producing that distinct antibody.
A gene has been discovered that can naturally suppress the signs of Alzheimer's Disease in human brain cells. The scientists have also developed a new rapid drug-screening system for treatments that could potentially delay or prevent the disease.
A new study has shown that coral outplant survival is likely to drop below 50% if sea surface temperatures exceed 30.5 degrees Celsius and that survival rates can also be predicted by considering temperature conditions in the year prior to outplanting.
A new study warns that the last remaining habitat for several endangered bird species in Europe could reduce by up to 50 per cent in the next century as farmers convert land to more profitable crops and meet increased demand for products such as olive oil and wine.
A study examining the urban microclimatic impact of the 2019-20 Australian bushfires has uncovered how they affect local meteorological and air quality. Its findings could help understand the potential consequences of an increased rate and extension of bushfires, and especially regarding improving risk preparedness and coping strategies.
Measurements by the GRACE-FO satellite mission show a decline in water storage in Central Europe by up to 94 percent compared with seasonal fluctuations. The changes are so serious that a recovery within one year is not to be expected. The water shortage in the years 2018 and 2019 is thus the largest in the entire GRACE and GRACE-FO measurement campaign of almost 20 years.
Scientists have applied liquid-metal synthesis to piezoelectrics, advancing future flexible, wearable electronics, and biosensors drawing their power from the body's movements. Piezoelectric materials such as atomically-thin tin-monosulfide (SnS) convert mechanical forces or movement into electrical energy. Along with their inherent flexibility, this makes them candidates for flexible nanogenerators in wearable electronics or internal, self-powered biosensors.
A baby girl in Texas -- born prematurely to a mother with COVID-19 -- is the strongest evidence to date that intrauterine (in the womb) transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can occur, according to a new report.
Patients with COVID-19 who have an acute ischemic stroke (AIS) experience more severe strokes, have worse functional outcomes and are more likely to die of stroke than AIS patients who do not have COVID-19. The wide range of complications associated with COVID-19 likely explain the worse outcomes.
New research has identified for the first time the specific brain cells that control how much sugar you eat and how much you crave sweet tasting food. The study specifically identifies the brain cells that respond to the hormone FGF21 to regulate sugar intake and sweet taste preference.
A groundbreaking study is the first to analyze the relationship between group behaviors, group type, group dynamics, and kinship of beluga whales in 10 locations across the Arctic. Results show that not only do beluga whales regularly interact with close kin, including close maternal kin, they also frequently associate with more distantly related and unrelated individuals. Findings will improve the understanding of why some species are social, how individuals learn from group members and how animal cultures emerge.
NASA’s Parker Solar Probe has captured unique images of comet C/2020 F3 (NEOWISE) and its two tails. C/2020 F3 (NEOWISE) was discovered on March 27, 2020 by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission. The comet’s nucleus is about 5 km (3 miles) across and is covered with sooty, dark particles. C/2020 F3 [...]
Over time goldenrod plants and the gall flies that feed on them have been one-upping each other in an ongoing competition for survival. Now, a team of researchers has discovered that by detecting the plants' chemical defenses, the insects may have taken the lead.
The quantum spin liquid (QSL) state is an exotic state of matter where the spin of electrons, which generally exhibits order at low temperatures, remains disordered. Now, scientists have developed a new material where a two-dimensional QSL state can be experimentally observed, advancing our knowledge of spin behavior, and getting us closer to next-generation ''spintronic'' devices.
A new study found that Black individuals were twice as likely as White individuals to test positive for COVID-19. The average age of all participants in the study was 46. However, those infected were on average 52 years old, compared to those who tested negative, who were 45 years old on average.
Some mandarin fish species (Sinipercidae) are pure fish-eaters, which feed exclusively on living juvenile fish - also of their own species. A research team has described the genome of four mandarin fish species and thus also identified genes for cannibalistic eating behavior. Knowledge of the connections between the genome and feeding behavior is of interest for sustainable aquaculture.
