Phys.org / New peptide catalyst enables stereoselective head-to-tail macrocycle synthesis
A team at ETH Zurich developed a new peptide-based organocatalyst that handles macrocycle formation from start to finish. Macrocyclic compounds are ubiquitous both in nature and in the chemical industrial setup. They are ...
Medical Xpress / Better sleep could reduce anxiety in later life
As humans grow older, their emotional stability and sleep patterns can change significantly. For instance, some past studies have found that many older adults find it harder to manage negative emotions, experience higher ...
Medical Xpress / Former American football players show higher risk of later-life memory and mental health issues
American football is a high-octane contact sport in which repetitive head impacts (RHI) are a common sight. Researchers investigated the link between playing football and brain health, memory, and mental well-being later ...
Phys.org / Superfluids emerge in 2D moiré crystal formed from time, study predicts
Conventional crystals are materials in which atoms arrange themselves in repeating spatial patterns. Time crystals, on the other hand, are phases of matter characterized by repeating motions over time without constantly heating ...
Phys.org / One-of-a-kind microscope reveals living cells in unprecedented detail
Stanford researchers have combined two microscopy techniques to create a one-of-a-kind instrument that can show cell structures interacting in real time at an unprecedented 120-nanometer resolution—the highest achieved ...
Phys.org / The Maya engineering paradox: Masters of water, prisoners of mercury
Under the supervision of Université de Montréal archaeology professor Christina Halperin, Ph.D. student Jean Tremblay spent six years, from 2018 to 2024, studying how the Mayan city of Ucanal managed its drinking water. ...
Phys.org / How moss helped solve a grave-robbing mystery
In 2009, a scandal was exposed at a cemetery just outside of Chicago. Workers at Burr Oak Cemetery in Alsip, Illinois, were accused of exhuming old graves, dumping the remains elsewhere on the cemetery grounds, and reselling ...
Phys.org / A new face for 'Little Foot,' the most complete Australopithecus skeleton to date
What did the face of our ancestors look like three million years ago? Our international team has answered this question by virtually reconstructing the facial fragments of Little Foot, the most complete Australopithecus skeleton ...
Phys.org / From water splitting to H₂O₂: A new method narrows carbon nitride photocatalyst design
Photocatalysis promises an efficient conversion of abundant solar energy into usable chemical energy. Polyheptazine imides have some key structural and functional twists that make them especially interesting for photocatalysis. ...
Phys.org / Study finds 77% of US national parks are highly vulnerable to climate change
National parks in the United States represent a treasure trove of natural, historical, and recreational landscapes, but their health is at risk. A comprehensive new study on the climate-change vulnerability of national parks, ...
Phys.org / What Geminga's 100 TeV cutoff may mean for cosmic-ray acceleration in the Milky Way
For the first time, the Tibet ASγ Experiment has successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec (approximately 3.3 light-years) within the gamma-ray halo surrounding the Geminga pulsar ...
Phys.org / Natural dye produced by Amazonian fungus can be used in cosmetics
Initial tests with a natural dye produced by the Amazonian fungus Talaromyces amestolkiae show that eco-friendly cosmetics, such as face creams, gel sticks, and shampoos, can be developed with antioxidant and antibacterial ...
