Phys.org / 'Atomic zoom' brings gum disease bacteria into sharp focus
The technology at the center of the growing "resolution revolution" has again shown its value to scientists at Yale by revealing the secrets of gum disease.
Phys.org / A severe El Niño could threaten something essential to half of humanity—rice
Forecasters expect the El Niño now underway in the tropical Pacific to strengthen into a strong or very strong climate driver later this year.
Phys.org / New research reveals the motivations and tactics used by call center fraudsters
A new study led by the University of Portsmouth lifts the lid on the tactics used by call center fraudsters in India, while revealing the shocking scale of the industry within the country. Published in the Journal of White ...
Phys.org / World Cup research reveals strategy to give teams a penalty-shootout edge
One of football's most iconic moments—the penalty shootout—may be far more strategic than previously thought, with new research challenging the notion that the team kicking first holds a major advantage.
Phys.org / Human activity has not always harmed biodiversity—quite the opposite
For millennia, farming in Switzerland did not reduce plant diversity but helped increase it, University of Basel researchers have shown in a detailed reconstruction covering the past 7,000 years. Only recent decades paint ...
Phys.org / Why some wolves react more strongly to trespassers: Breeders may hold key to scent-based barriers
Wolves use their urine to communicate with each other. A recent study looked at the reactions of a pack to the marking of an intruder. This is a first step toward understanding what attracts or repels canids.
Phys.org / The invasive fern that science misidentified for decades
Salvinia molesta can double its biomass in 36 hours. It spreads across ponds, lakes and slow-moving waterways in a smothering green mat, blocking sunlight, consuming oxygen and collapsing the ecosystems beneath it. Now present ...
Phys.org / 3D genome analysis of germ cell formation tracks 350 million years of vertebrate evolution
A research team led by the Universitat Autònoma de Barcelona (UAB) has revealed how the genome is reorganized in 3D during male germ cell formation in vertebrates, leading to important new insights into how biodiversity is ...
Phys.org / Camouflaging snails change color in the rain
How does a stripy tree snail hide from hungry birds? The Hypselostyla camelopardalis from the Philippines and Reinia variegata from Japan have both evolved a form of dynamic camouflage to survive. Their light-colored patterns ...
Phys.org / New findings on how malaria parasites invade human cells yield proof of concept for new antimalarial drug
For nearly half a century, scientists have known that malaria parasites force their way into human red blood cells through a ring-shaped structure called the moving junction. What no one could work out was what it actually ...
Phys.org / New way to clean up environmental pollution using phage bioaugmentation
The ability of bacteria to remove pollutants from soil, water, mine waste and other environments could be supercharged by a "friendly" compatible virus, according to a study led by Flinders University. The new insights, published ...
Phys.org / How a sugar building block influences viral attachment
Sialic acid is a natural sugar building block found on the surfaces of our cells. It acts as a protective and recognition molecule and plays a central role in the development of the nervous system. Following the modular principle, ...
