Blood types indicate greater risk for cancer
Offering a novel clue about the basic biology of pancreatic cancer, researchers at Dana-Farber Cancer Institute have confirmed a decades-old discovery of a link between blood type and the risk of developing the disease.

Watching evolution in real time
In 1831, the young Charles Darwin set off on the H.M.S. Beagle, a Royal Navy sloop bound for detailed surveys of South America. He took with him the first volume of the massive trilogy “Principles of Geology” by Scottish geologist Charles Lyell. (He had the other volumes sent later.)

Capillary formation’s mechanical determinants
Harvard researchers have established a link between the growth of blood vessels and the mechanical stresses caused by the environment within which the vessels grow, a new understanding that researchers hope can lead to novel disease treatments based on manipulating blood flow to living tissues.

Darwin’s empathy, imagination highlighted
On Feb. 12, the world celebrated the 200th anniversary of Charles Darwin’s birth. Much was made of his key idea, natural selection, and how it still resonates and informs science in the 21st century.

Bacteria have more to say than previously thought
Bacteria are the oldest living organisms, dating back 4 billion years. So it is only logical that they have evolved ways to communicate.

Science programs advancing
Harvard President Drew Faust today renewed the University’s commitment to the vision of advancing interdisciplinary, collaborative science in general, and the Department of Stem Cell and Regenerative Biology (SCRB), the Harvard Stem Cell Institute (HSCI), and the Wyss Institute for Biologically Inspired Engineering (WIBIE) in particular.

Exploring abundance under the sea floor
Called the North Pond Basin, the site — researchers at Harvard and beyond believe — can provide a window onto a vast world of subterranean microscopic life that extends kilometers below the Earth’s surface and which, according to rough estimates, could rival life above the surface in both diversity and sheer mass.

Neural wiring hints at nervous system gene limits
Genetics may play a surprisingly small role in determining the precise wiring of the mammalian nervous system, according to painstaking mapping of every neuron projecting to a small muscle mice use to move their ears. These first-ever mammalian “connectomes,” or complete neural circuit diagrams, reveal that neural wiring can vary widely even in paired tissues…

Neural mapping paints a haphazard picture of odor receptors
Despite the striking aromatic differences between coffee, peppermint, and pine, a new mapping of the nose’s neural circuitry suggests a haphazard patchwork where the receptors for such disparate scents are as likely as not to be neighbors.

Faculty of Arts and Sciences Standing Committees 2008-09
Upon the recommendation of the dean of the Faculty of Arts and Sciences (FAS), Harvard President Drew Faust has approved and announced the following Standing Committees. Standing Committees of the faculty are constituted to perform a continuing function. Each committee has been established by a vote of the faculty, and can be dissolved only by…

New obesity-related genes identified
A large international consortium has made significant inroads into uncovering the genetic basis of obesity, adding six new genetic variants to the two already linked to higher body mass index (BMI) in previous studies. Most of the newly discovered genes had never before been suspected of having a role in body weight and, curiously, many…

Research may lead to treatment for retinitis pigmentosa
Rods and cones coexist peacefully in healthy retinas. Both types of cells occupy the same layer of tissue and send signals when they detect light, which is the first step in vision.

Of Neanderthals and dairy farmers
Harvard Archaeology Professor Noreen Tuross sought to rehabilitate the image of Neanderthals as meat-eating brutes last week, presenting evidence that, though they almost certainly ate red meat, Neanderthal diets also consisted of other foods — like escargot.

Scientists explore nature’s designs
As a graduate student, Harvard physical chemist Joanna Aizenberg acquired a passionate curiosity about — of all things — sponges. She particularly liked the ones made of glass, whose apparent fragility belied the fact that they could withstand terrific pressure in the deep sea.

Quantum computers could excel in modeling chemical reactions
Quantum computers would likely outperform conventional computers in simulating chemical reactions involving more than four atoms, according to scientists at Harvard University, the Massachusetts Institute of Technology (MIT), and Haverford College. Such improved ability to model and predict complex chemical reactions could revolutionize drug design and materials science, among other fields.

A single gene leads yeast cells to cooperate against threats
An ingenious social behavior that mobilizes yeast cells to cooperate in protecting each other from stress, antibiotics, and other dangers is driven by the activity of a single gene, scientists report this week in the journal Cell. The cooperating cells use the same gene, dubbed FLO1, as a marker for detecting “cheaters,” cells that try…

New Guinea forest expands ‘observatory’
Just getting there takes hours of hot, sweaty hiking through lowland Papua New Guinea forests: three hours from the road to the base camp, then another seven to the site. That’s when the real work begins: tagging, measuring, and identifying 250,000 trees scattered over 50 hectares.

Joseph J. Schildkraut
For a period during the late 1950s and 1960s, psychiatry attracted some of the most capable graduates of US medical schools. Intrigued by the conceptual interest of psychoanalytic theory, and the possibility of treatment via the couch, these students chose for residency departments of psychiatry that featured grounding in psychoanalysis. One of these was Joe…

Global ‘chump change’ could provide biodiversity protection
Harvard biologist Edward O. Wilson said the Earth’s major biological hot spots could be conserved for roughly $50 billion— an amount he termed “chump change” in a world of trillion-dollar financial bailouts.
