Scientists from the USDA's Agricultural Research Service (ARS) and North Dakota State University (NDSU) recently found that when cattle were fed with the industrial hemp byproduct, hempseed cake, very low levels of Cannabis chemicals (cannabinoids) w.....»»
How to cool your brain? These warm-blooded animals use their nose
A research team led by Seishiro Tada and Takanobu Tsuihiji of the University of Tokyo shows that the living warm-blooded descendants of theropod dinosaurs, aided by larger nasal cavities, evolved a better nasal cooling system than cold-blooded animal.....»»
Engineered plants produce sex perfume to trick pests and replace pesticides
By using precision gene engineering techniques, researchers at the Earlham Institute in Norwich have been able to turn tobacco plants into solar-powered factories for moth sex pheromones......»»
Woolly mammoths evolved smaller ears and woolier coats over the 700,000 years that they roamed the Siberian steppes
A team of researchers compared the genomes of woolly mammoths with modern day elephants to find out what made woolly mammoths unique, both as individuals and as a species. The investigators report April 7 in the journal Current Biology that many of t.....»»
A cold-specialized icefish species underwent major genetic changes as it migrated to temperate waters, new study finds
Many animals have evolved to tolerate extreme environments, including being able to survive crushing pressures of ocean trenches, unforgiving heat of deserts, and limited oxygen high in the mountains. These animals are often highly specialized to liv.....»»
Study shows dramatic insect decline is also occurring in forests
The number of insects has been declining for years. This has already been well documented for agricultural areas. In forests, however, temporal trends are mostly studied for insect species that are considered pests......»»
Squash bees flourish in response to agricultural intensification
While pollinator populations of many species have plummeted worldwide, one bee species is blowing up the map with its rapid population expansion. The key to this insect's success? Its passion for pumpkins, zucchinis, and other squashes, and the massi.....»»
Malware and machine learning: A match made in hell
We’ve been developing machine learning-based cybersecurity systems for many years and began developing automation for analysis in our labs in 2005. These early automation projects have since evolved into full-blown machine-learning frameworks......»»

A new, sustainable source for a promising cancer killer
Plants produce all types of curious chemicals. Some deter predators. Some smell wonderful. Some even have medicinal value. One of these hidden gems is (–)-jerantinine A (JA), a molecule with remarkable anticancer properties, produced by a plant cal.....»»
China develops new way of poaching South Korean talent
China's approach to obtaining South Korean technological secrets seems to have evolved in recent years. In the past, Chinese entities poached engineers and acquired businesses from South Korea. Now they are setting up research and development subsidi.....»»
Scientists discover giant insect genome
The largest genome of any insect, seven times the size of the human genome, was recently discovered in a grasshopper. In a study published in PLOS ONE, researchers from the German Leibniz Institute for the Analysis of Biodiversity Change (LIB) and th.....»»

Insect Farming Is Booming. But Is It Cruel?
More than a trillion insects are raised each year as high-protein, low-carbon animal feed, but the practice might have an ethical blind spot......»»
The likelihood of academies of science recognizing the work of women researchers is improving
A researcher at the University of the Basque Country (UPV/EHU) has explored how the gender gap has evolved in two American academies: the National Academy of Science (NAS) and the Academy of Arts and Sciences (AAAS) in the election of academics in ps.....»»
Agriculture needs fresh approach to tackle growing problem of insect resistance to biopesticides, new analysis finds
Insect pests which attack crops have extraordinary powers to develop resistance to greener pesticides and a new way to manage resistance risks is needed, according to analysis by University of Stirling scientists......»»
Insular dwarfs and giants more likely to go extinct, finds islands study
Islands are "laboratories of evolution" and home to animal species with many unique features, including dwarfs that evolved to very small sizes compared to their mainland relatives, and giants that evolved to large sizes......»»
Ants avoid reproductive competition with close relatives, suggests study
Cooperation is a key innovation in evolution, from evolution of genomes and multicellular organisms to insect societies, such as ants and honeybees to human societies. Crucially, any cooperation is stable only when conflicts among group members are k.....»»
