Scientist Haifan Lin: From Mao’s China to Yale’s Stem Cell Center

Scientist’s journey includes moving research toward potential clinical advances

A significant turning point in the life of Haifan Lin, Ph.D., Eugene Higgins Professor of Cell Biology; professor of genetics and of obstetrics, gynecology, and reproductive sciences; and founding director of Yale’s Stem Cell Center, may have come when he was just 15. Already a high achiever, as he has been ever since, he completed high school three years younger than his classmates. (more…)

In the Age of Social Media, He’s a New Kind of Scientist

What does it mean to be a scientist? Far more than doing research in a lab, says Michael Johnson, whose unconventional passage into the field began with a bowling championship and a music degree.

“Think of it basically like a cheeseburger,” says Michael Johnson. He’s talking about the enzyme ribonucleoside-diphosphate reductase. (more…)

In conversation: scientist Ruth Blake on life aboard the E/V Nautilus

Yale geology and geophysics professor Ruth Blake recently completed a tour of duty as lead scientist aboard the exploration vessel Nautilus, during the Windward Passage leg of the ship’s 2014 exploration season.

The Windward Passage is the body of water between Cuba and Haiti, where the Atlantic Ocean flows into and exchanges water with the Caribbean Sea. Blake’s stint as lead scientist lasted Aug. 18–28.

Blake spoke with YaleNews about the scientific mission at the heart of the journey. (more…)

Neanderthal lineages excavated from modern human genomes

A substantial fraction of the Neanderthal genome persists in modern human populations. A new approach applied to analyzing whole-genome sequencing data from 665 people from Europe and East Asia shows that more than 20 percent of the Neanderthal genome survives in the DNA of this contemporary group, whose genetic information is part of the 1,000 Genomes Project.

Previous research proposes that someone of non-African descent may have inherited approximately 1 percent to 3 percent of his or her genome from Neanderthal ancestors. These archaic DNA sequences can vary from one person to another and were aggregated in the present study to determine the extent of the Neanderthal genome remaining in the study group as a whole. The findings are a start to identifying the location of specific pieces of Neanderthal DNA in modern humans and a beginning to creating a collection of Neanderthal lineages surviving in present-day human populations.

Scientists “Burst” Supercomputing Record with Bubble Collapse Simulation; Could Lead to Advances in Healthcare and Industrial Technology

– 15,000 bubbles are simulated using IBM BlueGene/Q “Sequoia” at 14.4 Petaflop of sustained performance, a 150-fold improvement over current state-of-the-art
– Destructive capabilities of collapsing bubbles are increasingly being studied in areas ranging from treating kidney stones and cancer to high pressure fuel injectors
– Research team named as a Finalist for the 2013 Gordon Bell Prize (more…)

Poetry is like music to the mind, scientists prove

New brain imaging technology is helping researchers to bridge the gap between art and science by mapping the different ways in which the brain responds to poetry and prose.

Scientists at the University of Exeter used state-of-the-art functional magnetic resonance imaging (fMRI) technology, which allows them to visualise which parts of the brain are activated to process various activities.

No one had previously looked specifically at the differing responses in the brain to poetry and prose. (more…)

Cutting Specific Atmospheric Pollutants Would Slow Sea Level Rise

Decreasing emissions of black carbon, methane and other pollutants makes a difference

With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow sea level rise this century.

Scientists found that reductions in four pollutants that cycle comparatively quickly through the atmosphere could temporarily forestall the rate of sea level rise by roughly 25 to 50 percent.

The researchers focused on emissions of four heat-trapping pollutants: methane, tropospheric ozone, hydrofluorocarbons and black carbon. (more…)
