Few fish can survive the immense pressure of living in the deep sea. The Mariana Trench can reach around 36,200 feet deep with pressures of over 1,000 atmosphere. Scientists have placed landers at various depths ranging from 16,400-34,750 feet along the walls of the trench and have discovered what appears to be the “World’s Deepest…

A new species of frog (Limnonectes larvaepartus) has been discovered in the rain forest of Sulawesi island in Indonesia. This species challenges the grade-school wisdom that taught us: ‘frogs lay eggs’. It looks like textbooks will need to be revised as this is the only known exception to that rule. Study author Dr. Jimmy McGuire (University…

Scientists have now determined the complete mitochondrial genome sequence of Aoluguya reindeer (Rangifer tarandus). I wonder if the sequence will hold any more clues as to why Rudolph’s nose is so red and bright. Although according to this prior blog entry perhaps it was the other 8 reindeer who were different… Source: Ju Y, Liu H, Rong M,…

Spend a Day With Some of the Nation’s Most Exciting Innovators at X-STEM!

As Dean Kamen, inventor of such amazing technologies as the the Segway human transporter and one of the world’s most advanced robotic arm prostheses, often says: “Our nation is enamored with sports and entertainment, but how can we groom kids to become as passionate about innovation?” At the Festival’s fascinating all-day X-STEM Symposium, presented by MedImmune…

Can you hear me now?

New research shows that pearlfish (Onuxodon fowleri) not only reside in black-lip pearl oyster shells, they also use the shells to amplify sounds created by vibrating their swimbladders. According to lead study author Dr. Loic Kéver, “amplification probably improves the efficiency of communication by increasing the propagation distance of the sounds.” Following high resolution CT scans,…

Will bees save us from baldness?

  Propolis is a resin-like compound honeybees collect to coat their hives. New research suggests that this compound may increase hair growth as observed in studies of mice. Although the researchers did not test propolis on balding mice, they did find faster hair growth in mice that had been shaved or waxed, which is somewhat…

Feeling tired? You’re not alone. A new study finds that many U.S. workers aren’t getting enough sleep, which is essential to optimal health, and that people who work multiple jobs are at heightened risk of getting less than the recommended hours of nightly rest.

New research from Vanderbilt University shows that hummingbirds and insects have a lot in common…when it comes to flying at least. The researchers placed nontoxic paint on the wing of a ruby-throated hummingbird at 9 different spots then videotaped the animal flying at 1,000 frames per second with 4 cameras simultaneously. Using 3D simulations of…

Not everyone gets their research written about by this week’s Nobel Prize winners: All mammals face the challenge of navigating in complex, three-dimensional (3D) environments, whether they are swinging from branch-to-branch in forests or burrowing underground tunnels. How does the brain maintain a sense of place and direction in 3D? In a beautiful study published…

In ongoing public health efforts to curb the obesity epidemic, better menu and nutrition labeling is often tapped as a low-cost way to help make the healthy choice, the easy choice. And while the evidence on the effectiveness of such interventions is still emerging, a recent study found that educating young people on the calories in sugar-sweetened beverages did make a positive difference.
