Phys.org / Carbon–bismuth bonds reveal that relativity blurs the textbook line between sigma and pi bonds
Brown University chemists have provided direct evidence that upends the textbook explanation of how triple chemical bonds work in heavy elements. In a study published in Science, the researchers show evidence that when atomic ...
Phys.org / First synthetic protein motor moves along DNA in controlled, programmable steps
Researchers from UNSW Sydney have built the first artificial protein motor capable of taking controlled, directional steps along a DNA track. The protein, dubbed Tumbleweed, moves by alternating between three "feet" that ...
Medical Xpress / HIV vaccine triggers broadly neutralizing antibodies in 44% of primates
A new HIV vaccine developed by La Jolla Institute for Immunology (LJI), Scripps Research scientists and IAVI has the potential to protect humans from developing HIV infection and AIDS. This HIV vaccine is the first to generate ...
Phys.org / 'Cosmic wallflowers' may hold the key to the origin of globular clusters
Astronomers using computer simulations have investigated whether a class of star clusters nicknamed "cosmic wallflowers" could be the long-sought ancestors of the globular clusters we see orbiting galaxies today. Their paper, ...
Phys.org / Drought threatens irrigation in northern Italy
Water reserves are being depleted rapidly in northern Italy, threatening farming as the region's main river dries up, local officials warned Friday.
Tech Xplore / Compostable circuit boards from citric acid waste could cut carbon dioxide footprint
Worldwide, discarded electronic toys, computers and smartphones are becoming an increasingly significant source of electronic waste. Electronic circuits are based on printed circuit boards (PCBs), which are typically made ...
Phys.org / Why bees are struggling to survive this summer
You may be spotting dead bumblebees lying on pavements near you during the summer months. There are several reasons for this, some related to the weather and some very much due to humans.
Phys.org / Using mechanical vibrations instead of magnetic memory for quantum computing
Quantum computers still face limits when it comes to storing information. Researchers at ETH Zurich are now turning to mechanical vibrations rather than electromagnetic memory. Their new vibrating memory can store significantly ...
Phys.org / New physics-based machine-learning method speeds search for 2D quantum materials
Researchers at The University of Manchester have developed a new computational approach to help identify two-dimensional materials that may host unusual quantum behavior. The work, published in Science Advances, focuses on ...
Tech Xplore / Man nearly sucked out of 'detached' window on Ryanair flight
A man was nearly sucked out of the window of a Ryanair flight when it "detached" midair en route to Germany, with other passengers pulling him back inside, witnesses and officials said Friday.
Phys.org / Ancient 100-kilometer Himalayan glacier once reached lower than many of India's famous hill stations
A new study published in Quaternary Science Reviews dates the dramatic collapse of one of the largest glaciers ever documented in the Himalayas. The findings overturn a long-held assumption about what sustains wet-climate ...
Phys.org / Quantum optics may turn this rare visual phenomenon into an eye test
Modern life depends on quantum physics. It makes technologies such as GPS navigation, MRI scanners and computer chips possible. Now, the same science may also lead to a new way to test the health of our eyes. A University ...
