Watching wisdom

By | June 12, 2009

As young assistant professors in the Harvard biology department of the 1950s and 60s, the eminent biologists linkurl:James Watson;http://en.wikipedia.org/wiki/James_D._Watson and linkurl:Edward O. Wilson;http://www.eowilson.org/ famously didn't get along, to say the least. Wilson once called Watson "the most unpleasant human being I have ever met."

Why we go gray

By | June 11, 2009

Researchers have identified the mechanism for why hair goes gray with age and stress -- and in the process discovered a novel response to DNA damage in stem cells, they report in the June 12 issue of __Cell.__ It's generally thought that accumulated DNA damage is a likely culprit in aging phenotypes such as graying hair, but researchers have been unable to show a direct link, said linkurl:David Fisher;http://www2.massgeneral.org/cancer-research/profiles.aspx?id=156 chairman of the department of

Minding the human genome gap

By | June 9, 2009

Many of the unsequenced gaps in the human genome arise because their DNA sequences cannot be read by the bacteria used in traditional sequencing methods, according to a linkurl:paper;http://genomebiology.com/2009/10/6/R60 published last week in __Genome Biology__. In the paper, a team of Broad Institute researchers report a simple, new way to fill in those gaps using next-generation sequencing technology.

Sens. to Sebelius: Support the NIH

By | June 9, 2009

Today on Capitol Hill, Department of Health and Human Services Secretary Kathleen Sebelius caught a little guff from Senators Tom Harkin (D-IA) and Arlen Specter (D-PA) about the paltry increase -- just about $442 million -- that HHS is proposing for the National Institutes of Health's 2010 budget.

Glucose yields sweet pest control

By | June 8, 2009

The key to fighting the ravages of termites and other insect pests could lie in the ubiquitous glucose molecule, tweaked to weaken insect immune systems, say researchers from the Massachusetts Institute of Technology. Formosan subterranean termites Photo by Scott BauerThe scientists have shown that the glucose relative, D-δ-gluconolactone (GDL), can disrupt the activity of a termite protein crucial for sensing and killing invading microbes, making the pests susceptible to pathogenic bacter

Egg size matters for lizard sex

By | June 4, 2009

New findings add a surprising twist to the already complex mechanism that determines whether reptile embryos develop to be males or females. An egg-laying lizard found in the hills of southeastern Australia controls the sex of its young through the size of its eggs, suggesting that female reptiles may actively dole out yolk to fine-tune the sex ratio of their offspring, researchers linkurl:report;http://www.cell.com/current-biology/abstract/S0960-9822(09)01128-2 online today (June 4) in __Curren
