Seeing ear to eye

By | July 1, 2010

Humans' sense of smell is far less powerful than sight, yet new findings suggest olfaction has a surprisingly significant influence on vision. Image: Flickr/linkurl:tuexperto_com3;http://www.flickr.com/photos/21626156@N02/2509246163/ The findings, published online today (July 1) in Current Biology, show that what you smell can alter your visual perception. Previous studies have linked vision with the senses of hearing and touch, "but it's kind of more surprising that olfaction -- smells -- cou

Earlier start to multicellular life?

By | June 30, 2010

Newly uncovered fossils hint that multicellular life may have evolved more than 2 billion years ago -- some 200 million years earlier than previously expected, according to a study published this week in Nature.

Gene + virus + injury = disease?

By | June 24, 2010

One of the most detailed studies to date of how the interaction between genes and environment results in disease has demonstrated that an inflammatory bowel disease resembling human Crohn's needs a specific mutation, virus, and injury to develop in mice.Cross section of colon tissue from apatient with Crohn's diseaseImage:Nephron via Wikimedia Commons "Environmental genomic issues are tough to crack," said linkurl:John Mordes,;http://www.umassmed.edu/igp/faculty/mordes.cfm professor of endocrin

New lab-grown lungs

By | June 24, 2010

Two new lab-grown versions of lungs may one day serve as a way to sidestep both animal testing and organ transplantation. Image: Wikimedia commons, Patrick J. LynchOne engineered rat lung, described in Science Express today (June 24), even successfully helped rats breathe for brief periods. "This is the first ever published paper that really demonstrates that regenerative medicine can provide an alternative to clinical transplantation of the lungs," said translational medical researcher Paolo

Plastic antibodies?

By | June 24, 2010

Antibodies are the main ingredient in a wide range of biopharmaceuticals, but making them is no picnic. Now, chemists have good evidence there may be an easier way: plastic. Currently, in order to manufacture antibodies, mice (or other live animals) are injected with a foreign antigen over several weeks, stimulating B cells in the bloodstream to produce antibodies. Those B cells must then be harvested from the mouse's spleen and transferred to a bioreactor where they are often fused with anothe

Gulf scientists "on the sidelines"

By | June 23, 2010

Federally organized research teams mobilizing to deal with the oil spill in the Gulf of Mexico are failing to adequately include local ecologists in their efforts, according to some Gulf Coast academic researchers.

Lose fin proteins, gain limb?

By | June 23, 2010

The vertebrate transition from fin to limb is one of the juiciest mysteries in evolutionary biology, and this week, scientists may have identified another clue to the puzzle. Published online today (June 23) at linkurl:Nature,;http://www.nature.com/nature/index.html a team of researchers describe two previously unknown proteins essential to fin development in bony fishes -- the loss of which may have been a key step in the evolution of fins to limbs during tetrapod development. "It's a very exc

Research underwater

By | June 22, 2010

Animal physiologist Richard Browning stood at the edge of the water, shocked. On Saturday night, May 1st, forecasters predicted the Cumberland River, running along the edge of linkurl:Browning's research farm;http://faculty.tnstate.edu/rbrowning/ at Tennessee State University in Nashville, would crest at only 35 feet (around 10 meters) on Sunday evening -- high, but not high enough to damage the farm. But when he and his team arrived Sunday morning, the river had risen to 38 feet. Half the farm

Scientist survivors

By | June 22, 2010

"I've always been a bit shy about talking about science," said Kerstin Zechner, a genetics graduate student at the University of Oxford. So when she heard about the online competition that let high school students decide whether a scientist is worthy of receiving a ₤500 prize, Zechner hesitated, and then decided to give it a shot. As part of a two-week-long online event that ran in March called "I'm a Scientist, Get me out of Here," Zechner and other scientists responded to any questions
