Scientists create new overwintering sites for monarch butterflies on a warming planet
The migration of the monarch butterfly is one of the wonders of the natural world. Each autumn, a new generation of monarch butterflies is born in the northern United States and southern Canada. Hundreds of millions of these butterflies then fly to t.....»»
Despite massive security spending, 44% of CISOs fail to detect breaches
Despite global information security spending projected to reach $215 billion in 2024, 44% of CISOs surveyed reported they were unable to detect a data breach in the last 12 months using existing security tools, according to Gigamon. Blind spots under.....»»
When hurricanes hit, online chatter can drown out safety messaging
When natural disasters strike, social networks like Facebook and X (formerly known as Twitter) can be powerful tools for public communication—but often, rescue workers and government officials struggle to make themselves heard above the general hub.....»»
Environmental DNA and epidemics in wood frogs: Collaboration examines eDNA"s precision in population size estimation

Chemists develop chiral DNA catalysts for asymmetric catalysis
Chemists from the National University of Singapore (NUS) have developed a way to make diverse chiral deoxyribonucleic acid (DNA) catalysts by merging DNA repair with biorthogonal chemistry, paving the way for more efficient and versatile approaches t.....»»
Bat data study reveals conservation priorities in San Diego County
A team of wildlife managers at the U.S. Geological Survey in San Diego, California, working with a colleague from the San Diego Natural History Museum, have uncovered the areas in San Diego County that need the most scrutiny if bat populations in the.....»»
Scientists discover how innate immunity envelops bacteria
The protein GBP1 is a vital component of our body's natural defense against pathogens. This substance fights against bacteria and parasites by enveloping them in a protein coat, but how the substance manages to do this has remained unknown until now......»»
Targeting "selfish" bacteria could optimize inhibitors that fight antibiotic resistance
As strains of pathogens resistant to frontline antibiotics become more common worldwide, clinicians are more often turning to combination treatments that degrade this resistance as a first treatment option......»»
Barnacle-inspired polymers could present new way to design antibiotics, researchers say
Scientific literature has shown that barnacles that cling to rocks at the seashore use naturally occurring chemicals to clear rock surfaces of bacteria in preparation for laying down their sticky "glue." Since bioengineering professor Abraham Joy's l.....»»
