Phys.org / Provenance study shows 19th century looted 'Incan mummy' was actually an Aymara man
In a recent study, Dr. Claudine Abegg and her colleagues analyzed the remains of a mummified cranium housed in the collections of the Museum of Cantonal Archaeology and History of Lausanne.
Phys.org / Scientists engineer plants to double carbon uptake ability and produce more seeds and lipids
Typically, plants rely on the Calvin-Benson-Bassham (CBB) cycle to convert carbon dioxide in the atmosphere to usable organic matter for growth. Although this cycle is the main pathway for carbon fixation in all plants on ...
Phys.org / Observations investigate the nature of a newly discovered odd radio circle
Astronomers from Ruhr University Bochum in Germany and elsewhere have conducted radio spectropolarimetric observations of a recently identified odd radio circle designated ORC J0356–4216. Results of the observational campaign, ...
Phys.org / How mice extend short-range ultrasound for public announcements
Mice often communicate in ultrasound, which is so high-pitched that it's beyond human hearing. Because these sounds don't travel very far, it was thought that they were only used for private, close-up conversations. New research ...
Phys.org / The sound of crying babies makes our faces hotter, according to new research
Hearing a baby cry can trigger a range of responses in adults, such as sympathy, anxiety and a strong urge to help. However, new research suggests that a deeper physical reaction is also occurring. A baby's cry, particularly ...
Phys.org / First-principles simulations reveal quantum entanglement in molecular polariton dynamics
This is what fun looks like for a particular set of theoretical chemists driven to solve extremely difficult problems: Deciding whether the electromagnetic fields in molecular polaritons should be treated classically or quantum ...
Phys.org / The oldest mummies in the world may hail from southeastern Asia and date back 12,000 years
Scientists have discovered what's thought to be the oldest known mummies in the world in southeastern Asia dating back up to 12,000 years.
Phys.org / Scientists uncover how cellular receptors trigger inflammation and sensory changes
In two new studies, scientists at Oregon Health & Science University have uncovered detailed blueprints of how certain molecular "gates" in human cells work—findings that could open doors to new treatments for conditions ...
Phys.org / New layered material successfully confines terahertz light to the nanoscale
A new study has successfully demonstrated the confinement of terahertz (THz) light to nanoscale dimensions using a new type of layered material. This could lead to improvements in optoelectronic devices such as infrared emitters ...
Phys.org / NASA analysis shows sun's activity ramping up
The sun has become increasingly active since 2008, a new NASA study shows. Solar activity is known to fluctuate in cycles of 11 years, but there are longer-term variations that can last decades. Case in point: Since the 1980s, ...
Phys.org / Ants defend plants from herbivores, but can hinder pollination by bees
Around 4,000 plant species from different parts of the world secrete nectar outside their flowers, such as on their stems or leaves, through secretory glands known as extrafloral nectaries. Unlike floral nectar, extrafloral ...
Phys.org / Scientists discover how nanoplastics disrupt brain energy metabolism
Scientists from the Trinity Biomedical Sciences Institute (TBSI) have discovered how nanoplastics—even smaller than microplastics—disrupt energy metabolism in brain cells. Their findings may have implications for better ...
