Hybrids between two species can produce “swarms” that flourish
Humans may be part of a hybrid swarm. And we’re making more of them. Enlarge (credit: Aurich Lawson | Getty Images) There are no wild ligers. Indeed, hybrids were once thought to be rare in nature—and of little conse.....»»
Genetic tracing at the Huanan Seafood market further supports COVID animal origins
A new international collaborative study provides a list of the wildlife species present at the market from which SARS-CoV-2, the virus responsible for the COVID-19 pandemic, most likely arose in late 2019. The study is based on a new analysis of meta.....»»
Moderate levels of exotic species invasions may help maintain biodiversity, study suggests
Globally, more than 13,000 plant species, equivalent to the entire native flora of Europe, have been naturalized outside their native ranges. A study, jointly conducted by scientists from China and the U.S., provides new insights about biodiversity,.....»»
How the Tibetan Plateau is helping us to understand the current and future climate
Imagine the conductor of a vast orchestra stood not at the front, but in the middle of all the musicians, dictating how they work together and the music they produce. The musicians are not stationary; they move past each other and interact, but all t.....»»
New technique zeros in on the genes that snakes use to produce venom
Only about 10% of the world's roughly 4,000 snake species have venom strong enough to seriously hurt a human, but that's enough for snake bites to be an important public health concern. To help better understand how snakes make their venom and how ve.....»»
Study identifies possible novel species in fish genus endemic to Neotropics
With 84 species currently described, Characidium may be the most diverse fish genus known to science. This is the conclusion reached by Brazilian scientists after analyzing more than 4,400 specimens of this genus of South American darters endemic to.....»»

Another new wasp species discovered by researchers
A newly identified wasp species, Chrysonotomyia susbelli, has been discovered in Houston, Texas, marking the 18th new species identified by Rice University's Scott Egan and his research team since 2014. The discovery, the fourth wasp species found on.....»»
Scientists have found evidence of past extreme solar storms—they could be disastrous for technology-based society
In September 1859, the same year that Darwin published "On the Origin of Species," telegraph systems across Europe and North America stopped working and started sparking, leading to fires in some cases......»»
DNA origami and fluorescent probes can precisely release molecular cargo
In the world of nanotechnology, the development of dynamic systems that respond to molecular signals is becoming increasingly important. The DNA origami technique, whereby DNA is programmed so as to produce functional nanostructures, plays a key role.....»»
"Emergency" declared over falling UK butterfly numbers
Conservationists on Wednesday voiced concern at a fall in the number of butterflies found in the UK, declaring a "butterfly emergency" and calling for greater protections for under-threat species......»»
Which plant species will survive the global change challenge?
In a temperate montane forest in southern Québec, all is quiet. But if you dig a little deeper, you'll see the landscape has a story to tell. Waterloo plant ecologist Dr. Julie Messier, alongside her collaborators from Sherbrooke, is uncovering vita.....»»
Walking the trees: Researchers trace how First Nations groups moved bunya pine and black bean trees
For millennia, Indigenous knowledge holders have passed down lore to the next generation. Much lore describes the relationships between people and Country, including custodial responsibilities to care for other species as kin......»»
Hybrid Chickadees Reveal How Species Boundaries Can Shift and Blur
When different chickadee species meet, they sometimes choose each other as mates—with surprising results.....»»
Going Back to the Moon, Researching Chickadee Hybrids and Understanding Addiction
This month’s issue covers the reasons it’s so hard to go back to the moon, the science of empathy and new advances in treating sickle cell disease.....»»
Public attention on the invasive lionfish helps monitor its ecological impact in real time
A new study from the Institut de Ciències del Mar (ICM-CSIC) has demonstrated that public interest in the lionfish (Pterois miles), an invasive species native to the Indo-Pacific, is aiding in monitoring its spread nearly in real time......»»
Q&A: Authors discuss addressing the crisis of species loss
No oncologist would wait for a patient's cancer to spread before treating it. Similarly, waiting to detect the potential loss of a species across all its known habitats means interventions are often too late to turn the tide of extinction, according.....»»
"Scuba-diving" lizards use bubble to breathe underwater and avoid predators
Presenting the world's smallest (and scrappiest) scuba diver: A species of semi-aquatic lizard produces a special bubble over its nostrils to breathe underwater and avoid predators, according to new research from Binghamton University, State Universi.....»»
Freshwater oysters could be key to developing stronger, "greener" adhesives
If you think oysters are just delicious seafood, think again. Freshwater oysters produce an adhesive that may hold the secret to developing more environmentally friendly glues with applications from dental care to construction and shipping. An intern.....»»
Team discovers naturally occurring DNA-protein hybrids
Thanks to a serendipitous discovery and a lot of painstaking work, scientists can now build biohybrid molecules that combine the homing powers of DNA with the broad functional repertoire of proteins—without having to synthesize them one by one, res.....»»
Fungi to the rescue: South African scientists use innovative approach to protect apple trees
