Phys.org / Rare blue optical transient points to possible new class of cosmic explosion
Chinese astronomers report the detection of a peculiar optical transient event that occurred in the center of a dwarf galaxy. The newly discovered event, designated AT2019ijn, is a fast-rising, slow-decaying blue optical ...
Phys.org / Biomolecular condensates reveal surprising activity as catalysts
Biomolecular condensates are ubiquitous in living cells, including bacteria, viruses, plants and mammalian systems. These membraneless bodies, or molecular communities made up of DNA, RNA and proteins, are where molecules ...
Phys.org / Saber-toothed cats' spinal tumors suggest inbred species struggled to survive
The fossilized spines of saber-toothed cats in the La Brea Tar Pits reveal evidence of an unexpectedly high prevalence of rare spinal nerve tumors, suggesting that the species became inbred just before extinction. These tumors, ...
Phys.org / New snail species bolster case for protecting Montenegro's biodiversity
The descriptions of the two new additions to the European snail fauna, named Cochlostoma komarnica and Cochlostoma dobrido, have been published in the open-access Biodiversity Data Journal.
Medical Xpress / Study finds new weak spot linked to DNA repair in aggressive, drug-resistant cancers
A new way for hard-to-treat cancer cells to protect themselves from being killed by anticancer drugs has been found. The novel method involves tumors hijacking specific defenses for repairing damaged DNA, which are easier ...
Tech Xplore / New tool identifies the sources of fake videos
Artificial intelligence can generate videos so realistic that distinguishing them from authentic footage is becoming increasingly difficult. But a computer science team led by researchers at UC Riverside has developed a tool ...
Phys.org / Plants know when to grow—and when to hold back, study finds
Researchers have uncovered a surprising mechanism that allows plants to carefully coordinate the formation and growth of new leaf parts. The study shows that the hormone auxin regulates different phases in organ formation ...
Phys.org / Virtual reality fish platform offers insights into the impact of artificial light on aquatic life
A virtual reality (VR) platform has given researchers new insights into how artificial light at night alters the way coral reef fish respond to predators. The study brings together, for the first time, the metabolic expertise ...
Phys.org / AI and robotics accelerate search for better gut microbiome therapies
Biomedical engineers at Duke University have demonstrated a method for systematically developing novel, complex combinations of probiotics and prebiotics to more effectively maintain gut health and treat various gastrointestinal ...
Medical Xpress / Two neural pathways reveal why habits form and vary in intensity
Habit formation describes the repeated performance of a behavior until it becomes routine: in other words, the shift from deliberate to automatic decision-making. This concept is often invoked as a way to improve one's life ...
Phys.org / Moth wings reveal an unexpected ability to smell plant chemicals
Insect wings are bristling with senses, feeling the wind blowing and even tasting potential mates, but little was known about whether moth wings are equipped with a sense of smell. Sonja Bisch-Knaden and Bill Hansson from ...
Tech Xplore / Seed crystals push solvent‑free perovskite cells to 25.53% efficiency
Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries, where they are helping to reduce reliance on electricity generated from fossil fuels. While most solar cells used today ...
