Phys.org / Polyphenol structures reveal why tea, cocoa and fruit compounds taste so different
A pilot study has developed a new sensory evaluation method that links the chemical structures of polyphenols with their distinct taste properties. Using trained human panelists, researchers showed that different polyphenols ...
Medical Xpress / Engineered Salmonella deliver cancer-killing viruses, shrinking liver and pancreatic tumors in mice
Researchers at the University of Massachusetts Amherst have designed non-toxic Salmonella bacteria to deliver viruses that are safe to humans but potent against liver and pancreatic cancer tumors—two cancers with an extremely ...
Phys.org / Cells have a built-in 'seatbelt' against sudden stress
When cells experience sudden physical stress, like stretching or pressure, they can activate a fast, protective mechanism that shields their nuclei from destruction, according to a new study published in the Biophysical Journal. ...
Phys.org / Animals were sharpening their senses long before the Cambrian explosion, ancient tracks reveal
Tracks left by some of the earliest complex animals are giving new insights into how they experienced the world. New research reveals how these creatures started to understand their surroundings, paving the way for animal ...
Phys.org / Dead Sea archaea sport reinforced swimming tail for hypersalty waters
Living in the Dead Sea would be a very unpleasant experience for most creatures. With salt concentration above 30% and temperatures ranging from 10–50°C, it takes unique environmental adaptations to survive in such harsh ...
Phys.org / Proteins can be selectively controlled with radio waves
In a significant advance in biological quantum sensing, a research team led by the Technical University of Munich (TUM) has discovered and tested a new mechanism of action in which proteins can be controlled with radio waves. ...
Phys.org / Nanoparticles inspired by lung fluid improve therapies targeting respiratory system
The CIC biomaGUNE Center for Cooperative Research in Biomaterials has developed pulmonary surfactant nanoparticles (the blend of lipids and proteins that line the alveoli and enables breathing), which are encapsulated in ...
Phys.org / Tessera AI model offers accessible way to view Earth
A foundation model trained on Earth observation data from Copernicus Sentinel-1 and Sentinel-2 has been made widely available to researchers, it was announced at a computer industry conference this week in Denver, U.S.
Phys.org / Meteors are 'extremely common.' What makes the one over New England 'rare'?
A sonic boom shook Boston and the larger New England area with the force of 230 tons of TNT. The source came from outer space. The Saturday afternoon event triggered shock waves online, with thousands inquiring what could ...
Phys.org / UN warns world to prepare for El Nino extreme weather
There is an 80% chance of the warming El Niño phenomenon developing between June and August, increasing the risk of extreme weather events, the World Meteorological Organization said Tuesday.
Medical Xpress / Unexpected chromosome interaction fuels aggressive cancers, researchers discover
Published in Nature, researchers at the University of Pittsburgh School of Medicine and UPMC Hillman Cancer Center report a previously unrecognized change in how the cell's genetic material is packaged into structures called ...
Phys.org / Student astronomer discovers 'Rosetta Stone' for mysterious cosmic signals
An international team led by astronomers at the University of Sydney has uncovered the clearest evidence yet for the origin of an unusual class of cosmic signals. In doing so, they have identified a rare stellar system that ...
