Male fruit flies found to transfer chemical to females to induce sleep, so they won"t mate with other males
A team of researchers from Bariloche Atomic Center and Fundación Instituto Leloir—IIBBA—CONICET, both in Argentina, has found that male fruit flies inject females with a chemical while mating that makes them sleep after sex so that they will not.....»»
MATE transporter facilitates bitter saponin transport from cytoplasm to vacuole
Domestic soybeans serve as an important source of healthy edible plant oil and high-quality plant protein in our food culture. In addition to the well-known components of oil (approximately 20%), protein (approximately 40%), and carbohydrates (approx.....»»
Catalyst search shows how computing can take the guesswork out of chemistry
Imagine synthesizing and then testing over 50 different complex molecules to identify the most effective catalyst for a particular chemical reaction. The traditional approach to developing new catalysts for chemical reactions in this "try it and see".....»»

Fruit fly model identifies key regulators behind organ development
A new computational model simulating fruit fly wing development has enabled researchers to identify previously hidden mechanisms behind organ generation......»»
Why parrots sometimes adopt—or kill—each other"s babies
Infanticide and adoption in the animal kingdom have long puzzled scientists. While both males and females of many species are known to kill the babies of their rivals to secure sexual or social advantage, other animals have been observed caring for t.....»»
Bio-inspired materials" potential for efficient mass transfer boosted by a new twist on a century-old theory
The natural vein structure found within leaves—which has inspired the structural design of porous materials that can maximize mass transfer—could unlock improvements in energy storage, catalysis, and sensing thanks to a new twist on a century-old.....»»
Ultrathin samples with surface phonon polariton enhance photoinduced dipole force
A new study has been led by Prof. Xing-Hua Xia (State Key Lab of Analytical Chemistry for Life Science, School of Chemistry and Chemical Engineering, Nanjing University). While analyzing the infrared photoinduced force response of quartz, Dr. Jian Li.....»»
DDT pollutants found in deep sea fish off LA coast raise questions about the pesticide"s continuing threat to wildlife
In the 1940s and 1950s, the ocean off the coast of Los Angeles was a dumping ground for the nation's largest manufacturer of the pesticide DDT—a chemical now known to harm humans and wildlife. Due to the stubborn chemistry of DDT and its toxic brea.....»»
Attosecond core-level spectroscopy reveals real-time molecular dynamics
Chemical reactions are complex mechanisms. Many different dynamic processes are involved, affecting both the electrons and the nucleus of the present atoms. Very often, the strongly coupled electron and nuclear dynamics induce radiation-less relaxati.....»»
Animal behavior research better at keeping observer bias from sneaking in—but there"s still room to improve
Animal behavior research relies on careful observation of animals. Researchers might spend months in a jungle habitat watching tropical birds mate and raise their young. They might track the rates of physical contact in cattle herds of different dens.....»»
Male or female? Scientists discover the genetic mechanism that determines sex development in butterflies
Scientists of the Biology Centre, Czech Academy of Sciences, in collaboration with University of Liverpool have found the genetic mechanism that determines whether individuals of the butterfly species Bicyclus anynana become male or female......»»
Cold sintering may rescue plastic, ceramics, battery components from landfills
Recycling does not necessarily prevent an item from eventually ending up in a landfill, according to Enrique Gomez, interim associate dean for equity and inclusion and professor of chemical engineering in the Penn State College of Engineering. Instea.....»»
New Nevada experiments aim to improve monitoring of nuclear explosions
On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear e.....»»
Novel chemical tool for understanding membrane remodeling in the cell
In a study published in Proceedings of the National Academy of Sciences, Umeå researchers describe a natural product-like molecule, Tantalosin, that inhibits interaction between two proteins in complexes that reshape membranes inside the cell......»»
Targeting friends to induce social contagion can benefit the world, says new research
A new study co-authored by Yale sociologist Nicholas A. Christakis demonstrates that tapping into the dynamics of friendship significantly improves the possibility that a community will adopt public health and other interventions aimed at improved hu.....»»
Scent sells—but the right picture titillates both eyes and nose, research finds
