‘Death protein’ may lead to drugs that force cancer cells to self-destruct
Scientists at Dana-Farber Cancer Institute have identified a previously undetected trigger point on a naturally occurring “death protein” that helps the body get rid of unwanted or diseased cells. They say it may be possible to exploit the newly found trigger as a target for designer drugs that would treat cancer by forcing malignant cells…

Cabot Science Library catches migration in exhibit case
Roadkill may seem an odd inspiration for a library exhibition, but when a colleague mentioned an article about the rising number of migratory animals killed on roads and highways, Cabot Science Reference Librarian Reed Lowrie knew he’d stumbled onto his next exhibit.

NYU chemist Robert Shapiro decries RNA-first possibility
Back in the depths of time, an event almost miraculously improbable happened, creating a long, unlikely molecule. And life arose on Earth. Or, if you prefer, back in the depths of time, in a soup of small, relatively common molecules, an unknown chemical reaction occurred, sustained itself, replicated … and life arose on Earth.

Major step forward in cell reprogramming
Imagine, if you can, a day within the next decade when a physician-scientist could remove a skin cell from your arm and with a few chemicals turn that fully formed adult cell into a dish of stem cells genetically matched to you.

Arctic ice is thinning steadily
There was a polar bear sighting at Harvard last week. At Pforzheimer House on Thursday (Oct. 2), global warming expert James J. McCarthy delivered a crisp summary of how fast ice is melting in the Arctic — and why we should care. The audience of 80 took in his companion slide show, including images of…

The pine beetle’s tale: Destructive insect has pharmaceutical potential
Researchers at Harvard Medical School and the University of Wisconsin, Madison, have discovered how beetles and bacteria form a symbiotic and mutualistic relationship — one that ultimately results in the destruction of pine forests. In addition, they’ve identified the specific molecule that drives this whole phenomenon.

Financial risk-taking behavior is associated with higher testosterone
Higher levels of testosterone are correlated with financial risk-taking behavior, according to a new study in which men’s testosterone levels were assessed before participation in an investment game. The findings help to shed light on the evolutionary function and biological origins of risk taking.

Seeing what they hear, to better understand ourselves
It was a long drive from St. Louis to Florida, but Darlene Ketten had finally made it. Standing in the warm surf of St. George Island, she watched with delight as tiny, colorful bean clams popped out of the sand and then quickly reburied themselves as the waves foamed around her calves.

Jamaican lizards’ calisthenics mark territory at dawn, dusk
What does Jack LaLanne have in common with a Jamaican lizard? Like the ageless fitness guru, the lizards greet each new day with vigorous push-ups. That’s according to a new study showing that male Anolis lizards engage in impressive displays of reptilian strength — push-ups, head bobs, and threatening extension of a colorful neck flap…

When genetics gets personal
Just five years after the Human Genome Project announced it had decoded the first human DNA, the era of personal genetics is dawning, bringing with it not just the promise of targeted, personalized medicine and a new level of self-knowledge, but also a host of ethical, legal, and practical issues. A new project out of…

Next-generation tool for visualizing genomic data introduced
Researchers are collecting vast amounts of diverse genomic data with ever-increasing speed, but effective ways to visualize these data in an integrated manner have lagged behind the ability to generate them. To address this growing need, researchers at the Broad Institute of MIT and Harvard have developed the Integrative Genomics Viewer (IGV), a novel and…

Aquatic genome captures foreign DNA
Long viewed as straitlaced spinsters, sexless freshwater invertebrate animals known as bdelloid rotifers may actually be far more promiscuous than anyone had imagined: Scientists at Harvard University have found that the genomes of these common creatures are chock-full of DNA from plants, fungi, bacteria, and animals.

Protective mechanism fails when obesity sets in
Reporting in the journal Cell Metabolism, researchers from the Harvard School of Public Health (HSPH) said they have shown for the first time that fat-storing cells, or adipocytes, contain a protective anti-inflammatory immune mechanism that prevents the cells from overreacting to inflammation-causing stimuli, such as fatty acids in the diet.

Animal interaction behind ‘Cambrian Explosion’?
Harvard Professor of Biology and of Geology Charles Marshall presented his Tuesday (April 29), suggesting that it was an increase in interactions between species, such as predation, that drove an escalating evolutionary process that led to the development of teeth and claws and the wide variety of characteristics that we see among Earth’s animals today.
