3-D image of live embryo turning itself inside out

Researchers have captured the first 3-D video of a living algal embryo turning itself inside out, from a sphere to a mushroom shape and back again. The results could help unravel the mechanical processes at work during a similar process in animals, which has been called the 'most important time in your life.'

Common back problems may be caused by evolution of human locomotion

A common spinal disease could be the result of some people's vertebrae, the bones that make up the spine, sharing similarities in shape to a non-human primate. The research suggests that the relatively quick evolution of the ability to walk on two legs may have had a substantial impact on modern human health.

Could smell hold the key to limiting or ending pesticide use?

Could smell hold the key to ending pesticide use? Sscientists may have uncovered a natural way of avoiding the use of pesticides and help save plants from attack by recreating a natural insect repellent. They have, for the first time, created tiny molecules which mirror a natural occurring smell known to repel insects.

Biologist to New England: Slow Down, Think Frog

Northern New England's annual amphibian migration is always perilous, but critters that cross roads to breed are facing an additional challenge this year: a delayed start after the long winter. Every spring, several species of salamanders and frogs travel to vernal pools —temporary bodies of water created by melted snow—...

Opinion: CO2 is the Demon Because Malthus and Ehrlich Were Wrong About Overpopulation

Guest opinion: Dr. Tim Ball The world focus on CO2 is simply the end objective of a much larger political agenda. The Club of Rome (COR) and then UNEP’s Agenda 21 under Maurice Strong created a political agenda based on certain assumptions all related to overpopulation. 1.

Grazoprevir/elbasvir combo shows high cure rate for patients with chronic HCV

Once-daily oral grazoprevir/elbasvir combination therapy, taken without interferon or ribavirin for 12 weeks, demonstrated high sustained virologic response rates for treatment-naive patients with cirrhotic or non-cirrhotic chronic hepatitis C virus (HCV) genotype 1, 4, or 6. Show More Summary

Sofosbuvir and peginterferon/ribavirin demonstrates virologic response rates in G3 hep C patients

New results demonstrate that hepatitis C (HCV)-infected genotype-3 (GT-3) patients, with and without cirrhosis, receiving 24 weeks of sofosbuvir (SOF) in combination with ribavirin (RBV) and peginterferon (PEG) achieved the highest sustained virologic response rates at 12 weeks (SVR12), observed in a Phase 3 study, to date.
