Phys.org / Between the Pampa and Patagonia: New clues about how ancient hunter-gatherers fed themselves
An archaeological study reveals how ancient hunter-gatherer groups lived—and survived—more than a thousand years ago in the transition zone between the Pampas and Patagonia in Argentina. The research, carried out by Martínez ...
Medical Xpress / Historical trends in U.S. heroin use: Initiation after 2000 differs from earlier patterns
The production, distribution, and consumption of illegal opioids create problems for public health and safety in many countries. Overdose rates are particularly high in Canada and the United States, which experienced three ...
Phys.org / Alloy-engineered valleytronics: Microscopic mechanism gives scientists precise control over how excitons behave
Scientists have observed a new microscopic mechanism enabling precise control of the magneto-optical properties of excitons in alloys of two-dimensional semiconductors. This discovery opens up tangible prospects for technological ...
Medical Xpress / Smarter tissue and organ repair thanks to next-gen hydrogel
A multidisciplinary team have built hydrogels built entirely from synthetic peptides so their properties can be precisely tailored through chemical design. By harnessing the power of collagen-inspired peptides and light-triggered ...
Medical Xpress / Kenya-Uganda trial reduces HIV incidence by 70% in rural populations
By pairing digital tools with tailored HIV services delivered by community health workers and clinicians, a study has reduced new HIV cases by 70% in rural Kenya and Uganda. This successful strategic implementation of existing ...
Phys.org / Scientists deliver new molecule for getting DNA into cells
Researchers from Tokyo Metropolitan University have created a new molecule which carries DNA into biological cells, to treat or vaccinate against illnesses. Many existing options rely on molecules with a strong positive charge, ...
Medical Xpress / Maternal infections during pregnancy increase the risk of suicidal behaviors in their offspring, study finds
Past medical research consistently showed that specific events unfolding during pregnancy can influence the health of their offspring after birth. While this has been widely observed in the context of physical health, for ...
Phys.org / Animal muscles inspire biomaterial design for agriculture, fabrics and medicine
Natural muscle fibers are made up of spring-like proteins that can contract and stretch without losing their original form, dissipate mechanical energy as heat and maintain incredible tensile strength for all sorts of physical ...
Phys.org / Auroras on Ganymede and Earth share striking similarities
New observations of Ganymede reveal a striking similarity between the auroras on the largest moon in the solar system and those on Earth. The international team of astrophysicists, led by researchers from the University of ...
Phys.org / Tuning in to fluorescence to farm smarter: Monitoring plant light use saves indoor farm energy costs
Plant owners with a so-called green thumb often seem to have a more finely tuned sense of what their plants need than the rest of us. A new "smart lighting" system for indoor vertical farms grants this ability on a facility-wide ...
Medical Xpress / Lifespan-extending treatments increase variation in age at time of death
A key goal in aging research is not just to extend life, but to ensure more people live longer and healthier lives with less variation in age at death, a concept known as "squaring the survival curve." Using a recent meta-analysis, ...
Medical Xpress / Cervical cancer rates plummet among states with high HPV vaccination rates
Cervical cancer rates are plummeting in states with higher rates of HPV vaccination, a new study reports. Overall, cervical cancers have declined by 27% among young women in the years since the human papillomavirus (HPV) ...
