The rotation of stars in galaxies such as our Milky Way is puzzling. The orbital speeds of stars should decrease with their distance from the center of the galaxy, but in fact stars in the middle and outer regions of galaxies have the same rotational speed. This may be due to the gravitational effect of…
Vaccinations are the world’s frontline defence against infectious diseases yet despite decades of interventions, unsafe injection practices continue to expose billions of people to serious infection and disease. Now, new technology from the University of South Australia is revolutionising safe vaccination practices through antibacterial, silver-loaded dissolvable microneedle patches, which not only sterilise the injection site…
A City of Hope scientist and his colleagues have developed a user-friendly approach to creating “theranostics” — therapy combined with diagnostics — that target specific tumors and diseases. Key to the process are molecules called metallocorroles, which serve as versatile platforms for the development of drugs and imaging agents. City of Hope’s John Termini, Ph.D.,…
A team of researchers, including two from the University of California, Riverside, has identified the genes responsible for the hallmark sour taste of many citrus fruits. Published Tuesday, Feb. 25 in Nature Communications, the research could help plant breeders develop new, sweeter varieties. Modern citrus varieties have been bred over thousands of years to generate…
DGIST research team succeeded in developing a microrobot that can reach the accurate location of cardiovascular disease such as the Chronic Total Occlusion by moving and steering the microrobot towards a desired direction inside complicated blood vessels. This research is expected to increase the success rate of treatment and shorten the time of cardiovascular disease…
Anyone who skis, wears glasses, uses a camera or drives a car is familiar with the problem: if you come into a humid environment from the cold, your eyewear, camera lens or windshield can quickly fog up. Researchers at ETH Zurich have now developed a new transparent material coating that greatly reduces this effect. Just…
Menstrual cycle may influence addiction risk in women, according to a new study in Biological Psychiatry by researchers at the National Institute on Drug Abuse and University of Maryland School of Medicine. In female rats, craving for cocaine during abstinence from the drug was stronger during estrus — the phase in which ovulation occurs —…
New HIV infections in southern Africa could be reduced substantially by offering entire communities voluntary HIV testing, and immediately referring those who test positive for HIV treatment in line with local guidelines, according to new research presented at the Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle, USA today. The HPTN071 (PopART) trial found…
Qubits, the units used to encode information in quantum computing, are not all created equal. Some researchers believe that topological qubits, which are tougher and less susceptible to environmental noise than other kinds, may be the best medium for pushing quantum computing forward. Quantum physics deals with how fundamental particles interact and sometimes come together…
The results of two new Regenstrief Institute trials published in the Journal of the American Geriatrics Society underscore and confirm the need to look to options other than medication to lower the duration or severity of delirium in intensive care unit (ICU) patients. “Looking at our large studies and other recent work, including several trials…
