Phys.org / Invasive species hit the Global South significantly harder than previously assumed
Invasive alien species are among the world's leading drivers of species extinction. However, previous global assessments of the geographic distribution of this damage suffered from a systematic "research bias": Because significantly ...
Phys.org / Light reveals transient electronic step behind a hidden state in metal-organic framework
A fleeting photoinduced electronic state and the subsequent formation of a photoinduced hidden state in a metal–organic framework were captured in just 30 femtoseconds by researchers at Science Tokyo, Tohoku University and ...
Phys.org / First 3D views explain how primate cone pigments distinguish red from green
Human color vision depends on three types of cone cells in the retina. Although all three contain the same light-absorbing molecule, 11-cis-retinal, differences in the surrounding protein determine sensitivity to red, green ...
Phys.org / Exploring why societies around the world no longer bury their dead at home
There are countless cultures and societies around the world, spanning thousands of years. One thing they all have in common is that death is a part of everybody's life. Examining how different societies commemorate their ...
Phys.org / Hidden DNA copying may give bacteria a faster route to antibiotic resistance
The dangers of antibiotic overuse have become increasingly clear in recent decades. Excessive use accelerates the evolution of bacterial resistance to antibiotics, raising the alarming prospect of infections that no longer ...
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 / 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.
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 / 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 / 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 ...
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 ...
Phys.org / A quantum heat engine that simultaneously provides work and refrigeration
The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous ...
