At least two different groups of Neanderthals lived in Southern Siberia and an international team of researchers including scientists from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now proven that one of these groups migrated from Eastern Europe. The researchers have now published their findings in the journal Proceedings of the National Academy of Sciences of the United States of America (PNAS).
After more than 70 years, a great mystery of zoology has been solved: Honeybees actually use different dance dialects in their waggle dance. Which dialect has developed during evolution is related to the radius of action in which they collect food around the hive.
This is reported by research teams from the Biocenter of Julius-Maximilians-Universität Würzburg (JMU) in Bavaria, Germany, and the National Centre for Biological Sciences (NCBS) in Bangalore, India, in the journal Proceedings of the Royal Society B.
Researchers from the Hong Kong University of Science and Technology (HKUST) have reported the world's first 1.5 μm III-V lasers directly grown on the industry-standard 220 nm SOI (silicon-on-insulators) wafers without buffer, potentially paving an opening to the "holy grail" for present silicon (Si-) photonics research.
Seamlessly bridging the active III-V light sources with the passive Si-based photonic devices, the demonstration could be deployed as light sources in integrated circuits to greatly improve circuit speed, power efficiency and cost-effectiveness.
HOUSTON - (March 4, 2020) - Step by step, scientists are figuring out new ways to extend Moore's Law. The latest reveals a path toward integrated circuits with two-dimensional transistors.
A Rice University scientist and his collaborators in Taiwan and China reported in Nature today that they have successfully grown atom-thick sheets of hexagonal boron nitride (hBN) as two-inch diameter crystals across a wafer.
Researchers of the Hubrecht Institute (KNAW) in Utrecht, The Netherlands, and the MRC Laboratory of Molecular Biology in Cambridge, United Kingdom, have discovered a new way in which the human body repairs DNA damage caused by a degradation product of alcohol. That knowledge underlines the link between alcohol consumption and cancer. The research groups of Puck Knipscheer and Ketan J.
A study conducted in Brazil by researchers at the University of São Paulo (USP) and the University of Campinas (UNICAMP) shows that if 25% of an Atlantic rainforest fragment that is approximately 1 hectare is deforested, then the local temperature will increase by 1 °C. Clear-cutting the entire fragment would increase the local temperature by as much as 4 °C. The findings are published in the journal PLOS ONE.
(Boston)--There is a trend in modern medical school curriculum design to integrate the basic sciences and clinical sciences. Integrating basic science education with its clinical application from the initial stages of learning is thought to improve retention of information and facilitate the transfer of knowledge to the clinical setting.
Researchers at the University of Illinois at Urbana-Champaign are using a new application of an existing imaging technique that may help detect tumors in humans.
The technique, super-resolution ultrasound localization microscopy, was used to visualize the distribution of blood vessels and measure oxygen levels in tumors. The study was carried out in chicken embryos, but the researchers hope to extend the studies in humans.
A caesarean birth had little impact on whether a child would go onto develop allergies, a new study led by the Murdoch Children's Research Institute (MCRI) has shown.
The research, published in the Archives of Disease in Childhood journal, found only a small link between caesarean delivery and asthma and no association between the delivery method and eczema or lung function.
Climate change is heating the oceans, which affects billions of marine microbes in ways scientists don't fully understand. In response, USC researchers have developed a model to forecast how these important organisms will adapt to warming seas.
An international team of scientists have discovered a new material that can be 3D printed to create tissue-like vascular structures.
In a new study published today in Nature Communications, led by Professor Alvaro Mata at the University of Nottingham and Queen Mary University London, researchers have developed a way to 3D print graphene oxide with a protein which can organise into tubular structures that replicate some properties of vascular tissue.
Individuals who experience the loss of a partner are less likely to be diagnosed with melanoma but face an increased risk of dying from the disease, according to research published in the British Journal of Dermatology.
The researchers, led by the London School of Hygiene & Tropical Medicine and Aarhus University Hospital, investigated whether bereaved individuals had a higher risk of being diagnosed with, or dying from, melanoma than the non-bereaved. They used data from two large population-based studies between 1997 and 2017 in the UK and Denmark.
Electrical stimulation benefited women with constipation in a recent clinical trial published in Alimentary Pharmacology & Therapeutics.
Psychological stress has been proposed as a risk factor for melanoma, but clinical evidence is limited. A recent British Journal of Dermatology study funded by the European Academy of Dermatology and Venereology looked for a potential link between the death of a partner, which is one of the most stressful life events, and melanoma. The research was carried out by the London School of Hygiene & Tropical Medicine and Aarhus University Hospital in Denmark.
To address obesity worldwide, changes are needed in both the availability of treatments and the attitudes of clinicians. That's the conclusion of a survey-based study of health professionals.
