Remembering what you just saw

New research suggests how visual information can be stored in short term memory
Drop your News-Letter for a minute and take a quick look around. Now pick up your paper again (welcome back!). How much of what you just saw do you remember? Visual information - and other sensory data - does not disappear from your brain the moment you stop perceiving it.… 1 Comment

A new twist in cancer's DNA modification

New findings indicate that some anti-cancer drugs may paradoxically cause cancer
Scientists have known for several years that hypermethylation, a chemical modification of DNA in which multiple small carbon groups help to deactivate the genetic material, is a major mechanism in many cancers. A wide range of chemotherapy agents act by promoting demethylation - removing those carbon groups - in hope of restoring the tumor cell's DNA to its normal state.… 2 Comments

Science in the News: Norovirus outbreak hits Mass. college campus

For 174 people at Babson College in Wellesley, Mass., life has been pretty miserable lately. The norovirus, a bug that causes stomach flu-like bouts of nausea, vomiting and diarrhea, has spread rapidly across the college's campus. After a few days in which the number of cases rapidly increased, the outbreak has finally started to slow.… Post the First Comment

Protein pathways help hungry yeast live longer

Researchers at the Hopkins School of Medicine have shed new light on a pathway of protein activity that allows a specific strain of yeast cells to survive far longer than usual under starvation conditions. The findings could have implications for studies on human aging.… Post the First Comment


Natural orifice surgery: a less scarring option?

A woman is lying on the operating table. Her kidney is being removed for organ donation. The surgeon makes three cuts, each less than a centimeter long, in her abdomen. A couple hours later, her kidney is out, fully intact. Wait a minute, you might be thinking. Post a comment

You may have missed... Antarctic ice shelf collapsed last week

An ice bridge connecting the vast Wilkins ice shelf - an ice mass about the size of Connecticut - to Antarctica splintered into hundreds of smaller pieces after it broke apart from the continent late last week. Ice shelves like the Wilkins take centuries to develop, yet the destruction of a large portion of it occurred in just two days. Post a comment

Mosquito immune system can fight malaria

Hopkins researchers have discovered a possible new means to control malaria even before it infects a person. The malaria parasite is transmitted to humans by a mosquito. This discovery would allow the mosquito's own immune system to attack the parasite. Normally, Anopheles mosquitoes carry malarial organisms without their immune systems challenging the parasite.
