New research using publicly-shared DNA barcodes and citizen science images have provided new evidence on the establishment and spread of a biological control agent used for the control of the major invasive shrub Lantana camara.
Do embedded counseling services in veterinary education work? A new study says ‘yes’
Embedded counseling services are becoming increasingly common in veterinary medical programs, but their effectiveness has not historically been measured. A new study revealed that these programs may not only enhance access to mental health care but also lead to significant reductions in psychological distress among veterinary trainees.
Soft tissue from a 183 million-year-old Jurassic plesiosaur analyzed
Researchers have analyzed the soft tissue from a fossilized plesiosaur for the first time. The results show that the long-necked marine reptile had both smooth and scaly skin. This was likely so it could both swim rapidly and move along rough seabeds.
Some species of baleen whales avoid attracting killer whales by singing too low to be heard
New research finds some baleen whale species call at such deep frequencies that they're completely undetectable by killer whales, which cannot hear sounds below 100 hertz. These also tend to be the species of baleen whales that flee in the face of attack from killer whales.
Researchers achieve total synthesis of ibogaine
Researchers have achieved total chemical synthesis of the psychoactive compound ibogaine and its analogs from pyridine. The discovery will make it easier to explore the therapeutic possibilities of ibogaine.
New technology lights way for accelerating coral reef restoration
Scientists have developed a novel tool designed to protect and conserve coral reefs by providing them with an abundance of feeding opportunities.
Scientists discover brain mechanism that helps us overcome fear
Researchers have unveiled the precise brain mechanisms that enable animals to overcome instinctive fears. The study in mice could have implications for developing therapeutics for fear-related disorders such as phobias, anxiety and post-traumatic stress disorder (PTSD).
Ice streams move due to tiny ice quakes
An international team of researchers has shown that countless tiny ice quakes take place in one of Greenland's mightiest ice streams. This finding will allow the flowing of the ice sheet and associated changes in sea level to be estimated more accurately.
Mantis shrimp clubs filter sound to mitigate damage
Mantis shrimp withstand repeated high-impact forces without structural damage. Researchers discovered the shrimp's clubs feature a protective pattern that controls how stress waves travel through its body. The patterns resemble herringbone and twisted, corkscrew arrangements. Insights from this discovery could inspire advanced protective materials for reducing blast-related injuries.
Drying and rewetting cycles substantially increased soil CO2 release
Soil incubation experiments revealed a comprehensive increase in CO2 release by drying-rewetting cycles (DWCs) among Japanese forests and pastureland soils, suggesting a significant contribution of the DWCs-induced destruction of microbial cells and reactive metal-organic matter complex to the CO2 release increase.
