Phys.org / Cyclic catalysts use sunlight and air to regenerate during pharma ingredient synthesis
In chemical processes for producing pharmaceuticals, catalysts are a core technology that determines production speed and cost. However, until now, there has been a trade-off between "precise but disposable catalysts" and ...
Phys.org / Mercury scout mission concept with solar sail propulsion
The planet Mercury is the closest planet to the sun, and also the most difficult for spacecraft to visit and explore. This is because as spacecraft get closer to Mercury, the sun's enormous gravity pulls in the spacecraft, ...
Phys.org / Tasmanian tiger lives on in Arnhem Land rock art
The striped dog-like marsupial we know as the Tasmanian tiger has long been surrounded by mystery, and the subject of scientific curiosity. Now, newly discovered rock art depicting Tasmanian tigers and Tasmanian devils in ...
Medical Xpress / Higher‑level brain systems that interpret perception may play a central role in imagination
Imagination is one of the most powerful things our brains can do. We can relive past events while taking a walk, rehearse future conversations through inner speech or sense the heat of a fire without touching it—allowing ...
Phys.org / Earthquake off Indonesia topples buildings, kills 1 person and sets off small tsunami
An undersea magnitude 7.4 earthquake toppled buildings in parts of northern Indonesia, sent people fleeing from their homes, killed at least one person and generated a small tsunami Thursday.
Phys.org / Viruses 'eavesdrop' on each other—but it can backfire
University of Exeter scientists studied chemical communication by phages (viruses that infect bacteria). The phages assessed in the study have two choices when they enter a cell: lie dormant or kill the cell and release new ...
Medical Xpress / Placing fruit and vegetables near store entrances can improve sales and diet quality
Placing fruit and vegetable sections near supermarket entrances increases the amount purchased and may improve the quality of women's diets, according to a new study published in the journal PLOS Medicine.
Phys.org / Stabilized laser components could shrink quantum computers from room- to chip-scale
Scientists in the Riccio College of Engineering at the University of Massachusetts Amherst and the University of California Santa Barbara have demonstrated key laser and ion trap components necessary to help drastically shrink ...
Medical Xpress / Celiac disease may blunt high-fiber benefits when key gut microbes are missing
Many people with celiac disease are advised to eat more fiber to support digestion and manage symptoms, either through diet or prescribed fiber supplements. New research from McMaster University shows that the benefits of ...
Phys.org / Parasites defy biodiversity rules, thriving far from the equator
For decades, scientists have observed a clear pattern across the natural world: biodiversity tends to be higher near the equator and lower toward the poles. Known as the latitudinal diversity gradient (LDG), this trend holds ...
Phys.org / Seals use whisker movement to follow underwater trails—an approach that could improve robotic sensing
Seals are carnivorous marine mammals that are well adapted to hunting for fish underwater, where visibility is poor. In such conditions, seals rely on their highly sensitive whiskers to detect tiny water movements left behind ...
Phys.org / Study explains Antarctic sea ice growth and sudden decline
A new Stanford University study has helped solve a mystery about dramatic swings in sea ice extent around Antarctica.
