Four bright lasers, the most powerful ever put on a telescope, fire into the night sky to create an artificial guide star for the European Southern Observatory's Very Large Telescope at the Paranal Observatory in Chile.
Will the first astronaut on Mars work for SpaceX or NASA — or both?
An important new function of genes in the Fanconi anemia pathway has been identified by researchers – a finding that could have implications for development of new therapies to treat this disorder and some cancers.
Sticking to a Mediterranean style diet might slow down aging, a new study has found. Mediterranean style diet, tested in the project, significantly decreased the levels of the protein known as C-reactive protein, one of the main inflammatory marker linked with the ageing process. Another positive effect of this diet was that the rate of bone loss in people with osteoporosis was reduced. Other parameters such as insulin sensitivity, cardiovascular health, digestive health and quality of life are yet to be analyzed.
Research has found a shortfall in the uptake of influenza and pneumococcal vaccinations among those diagnosed with rheumatoid arthritis (RA), potentially increasing their infection risk.
An experimental study has found that readers rate texts generated by algorithms more credible than texts written by real journalists.
How species genetically adapt to their environment is a central question related to the evolution of biodiversity. In a new study scientists report that whole genome sequencing of Atlantic and Baltic herring revealed hundreds of loci underlying adaptation to the brackish Baltic Sea or timing of reproduction. The study is published today in eLife.
A new subgenus of plants has officially been called Jamesbondia after the notable American ornithologist James Bond, whose name Ian Fleming is known to have used for his eponymous spy series.
Both a high-intensity functional exercise programme and a non-exercise group activity, conducted among older care facility residents with dementia, reduced high levels of depressive symptoms. However, exercise had no superior effect on depression, according to a new dissertation.
A new study suggests that women are particularly susceptible to the pain-relieving placebo effect of vasopressin. Placebos are used to help accurately measure clinical responses/outcomes when studying the effects of medications, therapies, and other treatments. The well-known "placebo effect" is a phenomenon whereby a patient's condition improves or a patient experiences side effects despite having received a "fake" treatment.
Exercise can have a positive influence on certain symptoms of multiple sclerosis, say researchers. Patients who do yoga and aquatic exercise suffer less from fatigue, depression and paresthesia, as reported by researchers.
A clean, climate-friendly energy source that is virtually inexhaustible: This is the promise artificial photosynthesis holds. Chemists have now got one step closer to reaching this goal.
Women with poor physical fitness display significantly higher platelet activation than women with average to very good fitness. Platelet (thrombocyte) activation can lead to the formation of potentially life-threatening blood clots. These blood clots can block blood vessels (thrombosis) and cut off the blood supply to organs.
Scientists are aiming to develop advanced food manufacturing technologies by combining expertise in food, material science and 3D printing technology. Healthy snacks with great textures are in increasing demand among consumers. Researchers have the long-term vision of developing high-tech vending machines that provide customized purchases.
Predictions from quantum physics have been confirmed by countless experiments, but no one has yet detected the quantum physical effect of entanglement directly with the naked eye. This should now be possible thanks to an experiment proposed by theoretical physicists. The experiment might pave the way for new applications in quantum physics.
Scientists have developed a new, simple and quick way to make any number microlasers on a single structure. Microlasers are tiny optical devices a few tens of micrometres in diameter that are able to create intense light with only one colour or wavelength.
Tubular microtunnels believed to be the trace fossils formed by microbes inhabiting volcanic rock interiors have only been reported in oceanic and subglacial settings. This is the first observation of such features in basaltic volcanic glass erupted in a continental lake environment, the Fort Rock volcanic field.
Community-based social groups could play a crucial role in empowering people with early-onset dementia, according to new research. The research focused on an independently run program known as Paul's Club, which offers social and recreational activities three days a week out of a hotel in downtown Vancouver. Members range in age from mid-40s to late 60s.
The nerve agent sarin causes a deadly overstimulation of the nervous system that can be stopped if treated with an antidote within minutes of poisoning. Today, a ground-breaking study describes in detail how such a drug works.
Babies whose moms were vaccinated against the flu while pregnant had a 70 percent reduction in confirmed flu cases compared with infants whose moms weren't immunized, study finds.
