An international team has made a key discovery related to 'presolar grains' found in some meteorites. This discovery has shed light on stellar explosions and the origin of chemical elements. It has also provided a new method for astronomical research.
Bioengineers at the University of California San Diego used genetic engineering and laboratory evolution to test the functionality of DNA placed into a new species and study how it can mutate to become functional if given sufficient evolutionary time.
A new study from the Regenerative Bioscience Center at the University of Georgia is the first to suggest that COVID-19 does not directly damage taste bud cells.
A new study suggests that future reductions in seasonal snowpack as a result of climate change may negatively influence forest growth in semi-arid climates, but less so in wetter climates.
A simple blood test that does not require overnight fasting has been found to be an accurate screening tool for identifying youth at risk for type 2 diabetes and heart disease risk later in life.
Biological sex is typically understood in binary terms: male and female. However, there are many examples of animals that are able to modify sex-typical biological and behavioral features and even change sex. A new study, which appears in the journal Current Biology, identifies a genetic switch in brain cells that can toggle between sex-specific states when necessary, findings that question the idea of sex as a fixed property.
NEWCASTLE UNITED officials have spoken to Bournemouth about strike duo Callum Wilson and Josh King – but Steve Bruce faces a huge battle to persuade either to move to St James’ Park.
The city of Melbourne, Australia, is currently under some of the world's strictest pandemic lockdown measures. Residents have to be home by 8 p.m., and anyone who tests positive for COVID-19 can expect frequent, unannounced visits by police to ensure they're staying home. Today, on Front Burner, we speak to Melissa Davey, Australian bureau chief for The Guardian, to find out how a country — one that had so quickly flattened the curve early on in the pandemic — is now in the grips of a second wave of COVID-19.

(Karlsruher Institut für Technologie (KIT) ) Autonomous driving, electromobility, synthetic fuels: the mobility in our world is changing rapidly. Small and medium-sized enterprises (SMEs) in Baden-Württemberg are supported in this transformation by the "Technologiekalender Strukturwandel Automobil Baden-Württemberg" initiative. This technology calendar for structural change in automotive for Baden-Württemberg was co-developed by scientists from Karlsruhe Institute of Technology (KIT).
(International Vaccine Institute) The flag of Finland was raised at the International Vaccine Institute (IVI) Headquarters today during a ceremony welcoming the country's accession to IVI. Finland joined the Seoul-based international organization dedicated to vaccines for global health in response to the COVID-19 pandemic, committing an annual contribution of 500,000 EUR during the period of 2020 - 2025 to support IVI's core operations and 500,000 EUR for COVID-19 vaccine research and development this year.
Whole grain labels are confusing to consumers, according to a new study that found many made the wrong choice when asked to pick the healthier option based on product labels. The researchers, from Tufts University and NYU, say the results provide legal evidence for changes in labeling policies.
A new theoretical framework shows that many properties of neural connections help biological circuits produce consistent computations.
Secondary school students perform better in natural sciences and mathematics and are more motivated when digital tools are used in instruction. However, success depends on the design of the tools used. Success levels are higher when children and young adults do not study alone and when digital instruction is accompanied by paper-based teaching materials, according to the conclusion reached by one of the largest investigations on the topic, evaluating approximately 90 individual studies.
Automatic gratuities leave restaurant patrons with a bad taste, even when the meal and the service were excellent, new research from Washington State University indicates.
Scientists are closer to gaining the upper hand on Huanglongbing, a disease that has wiped out citrus orchards across the globe. New models of the bacterium linked to the disease reveal control methods that were previously unavailable.
A research group from Tel Aviv University (TAU) successfully reduced metastatic spread following tumor removal surgery in colorectal cancer patients. Using a short medication treatment around the time of the surgery, the researchers were able to reduce body stress responses and physiological inflammation during this critical period, preventing the development of metastases in the years following the surgery.
The extent of Southeast Michigan's tree canopy and its urban sprawl both increased between 1985 and 2015, according to a new University of Michigan study that used aerial photos and satellite images to map individual buildings and small patches of street trees.
Modelling the predicted movements of pervasive sap-sucking tiny insects before they infest banana crops has the potential to become a key tactic in the fight against a devastating virus, according to QUT research. Banana bunchy top virus (BBTV) is an aphid-transmitted banana disease that has been in Australia since 1913. QUT researchers have designed a model that tracked the probability of a banana plant being infected by aphids that carried the disease, with the findings published in PLOS Computational Biology.
Each week a woman consumes alcohol during the first five to 10 weeks of pregnancy is associated with an incremental 8% increase in risk of miscarriage, according to a study by Vanderbilt University Medical Center (VUMC) researchers.
Irina Shtangeeva is a researcher at the Department of Soil Science and Soil Ecology, St Petersburg University. She has studied the ability of wheat and couch grass to accumulate toxic substances. Both plants were capable of absorbing various chemical elements from contaminated soils. Although the plants were able to accumulate high concentrations of toxicants, they could survive under negative environmental conditions
A new theoretical method paves the way to modelling the interior of the ice giants Uranus and Neptune, thanks to computer simulations on the water contained within them. The tool, developed by scientists from SISSA in Trieste and the University of California at Los Angeles, allows one to analyse thermal and electric processes occurring at physical conditions that are often impossible to reproduce experimentally, with a much easier and low-cost approach.
Magnetic hyperthermia therapy (MHT) as a noninvasive local treatment strategy is able to ablate tumors. There is still a demand to find new magnetocaloric agents with strong AMF-induced heating performance and excellent biocompatibility. The eddy thermal effect of magnesium alloy (MgA) could be employed for MHT to effectively ablate tumors was reported by scientists based in China. Considering the wide clinical use of implantable MgA devices, such a strategy holds great promise in clinical translation.
Corals and cave carbonates can reveal the temperatures that prevailed at the Earth's surface at the time they formed. An international team of geoscientists led by Goethe University Frankfurt, Germany, has developed a new method that makes it possible to identify whether the composition of these deposits was exclusively controlled by temperature, or if the formation process itself exerted an additional control. The new method allows scientists to determine past Earth surface temperatures more reliably.
Sars-Cov-2 viruses can be inactivated using certain commercially available mouthwashes. This was demonstrated in cell culture experiments. High viral loads can be detected in the oral cavity and throat of some Covid-19 patients. The use of mouthwashes that are effective against Sars-Cov-2 could thus help to reduce the viral load and possibly the risk of coronavirus transmission over the short term.
We are all familiar with the old adage "fighting like cat and dog", but a new scientific study now reveals how you can bid farewell to those animal scraps and foster a harmonious relationship between your pet pooch and feline friend.
