A team of paleontologists and mechanical and biomedical engineers has compared CT scans of the fossilized bones of hadrosaurs and other dinosaurs with bones of extinct and living mammals and found that the dinosaur trabecular bone architecture was uniquely capable of supporting large weights (up to 47,000 kg) and different …

Opioid receptors in the inner ear can cause partial or full hearing loss, according to new research from Rutgers New Jersey Medical School and New Jersey Poison Information and Education System. Inner ear anatomy. Image credit: Medical Gallery of Blausen Medical 2014, doi: 10.15347/wjm/2014.010. “Ototoxicity, or ‘ear poisoning,’ is a …

In a new study published this month in the journal Biosensors and Bioelectronics: X, a team of scientists at Washington University in St. Louis showed how they were able to hijack the olfactory system of the American grasshopper (Schistocerca americana) to both detect and discriminate between different explosive scents — …

An international team of researchers has sequenced and analyzed a complete nuclear genome and 14 mitochondrial genomes from the extinct woolly rhinoceros (Coelodonta antiquitatis) and found that its population remained stable and diverse until only a few thousand years before it disappeared from Siberia, when temperatures likely rose too high …

Study: Floral Vibrations by Buzz-Pollinating Bumblebees More Powerful Than Their Flight or Defensive Buzzes Buzzing by buff-tailed bumblebee (Bombus terrestris audax) workers during pollen foraging is much more powerful than that used for defense or flight, according to new research from the University of Stirling. The buff-tailed bumblebee (Bombus terrestris). …

Diverse Strains of Smallpox Virus Were Widespread in Viking Age, New Study Shows Smallpox, caused by the variola virus, is one of the most devastating human diseases. Smallpox killed millions of people but drove Edward Jenner’s invention of vaccination, which eventually led to the annihilation of the virus, declared in …

Sodium Regulates Circadian Clock in Mice, New Study Shows A new study published this week in the journal Nature shows that injecting mice with a salt solution (hypertonic saline) leads to the activation of neurons associated with the suprachiasmatic nucleus, the brain’s master circadian clock. The suprachiasmatic nucleus of a …

Study: Staring at Deep Red Light Can Improve Naturally Declining Vision Looking at 670-nm red light for three minutes a day can significantly improve cone color contrast sensitivity (the ability to detect colors) and rod sensitivity (the ability to see in low light), according to a new study published in …

Chicxulub Asteroid Caused End-Cretaceous Mass Extinction, New Study Confirms The end-Cretaceous mass extinction 66 million years ago eradicated roughly 75% of the animal and plant species on Earth, including whole groups like non-avian dinosaurs and ammonites. Debate lingers over what caused this extinction, with intense volcanic activity in India’s Deccan …

Sled Dogs Emerged Over 9,500 Years Ago in Siberia: Study An international team of researchers has sequenced the genomes of 10 modern sled dogs, an ancient sled dog and an ancient wolf, both from Siberia, and analyzed their genetic relationships with other modern dogs. They’ve found that sled dogs represent …
