Prey-tell: Why Right Whales Linger in the Gulf of Maine

As they might with most endangered animals, scientists consider the whereabouts and activities of right whales extremely important. “It is helpful to know where they go, why they go there and what they do when they’re there,” says Mark F. Baumgartner of the biology department at the Woods Hole Oceanographic Institution (WHOI).

Baumgartner and his colleagues studied the behavior of right whales and sei whales—both endangered species of baleen whales—in the waters of the Gulf of Maine to the east of Nantucket. They found that the location, the length of stay, and perhaps the very abundance of the whales may be dependent on an interesting vertical migration pattern by the copepods on which the whales feed. It seems to be a case, he said, of “how the behavior of the prey influences the behavior of the whales.” (more…)

*BizSpark One startup Soundtrckr lets listeners discover, play and share music on their terms — alongside their friends.*

REDMOND, Wash. — April 27, 2011 — Soundtrckr, a BizSpark One startup, mashes Internet radio with social networking and location-awareness to help users create a soundtrack for their lives.

Sometimes, opportunity presents itself when least expected. That’s what Daniele Calabrese, founder and CEO of Soundtrckr, discovered as he boarded a plane bound to Philadelphia from Madrid. Calabrese was launching a new concept in radio called Soundtrckr, a geo-social Internet music service. In its infancy, Soundtrckr just needed the right connections to take it to the heights Calabrese was convinced it could reach. He sat down and met his seat mate. (more…)

Bringing more Power to African Farmers Through Simple Technology

In a room in the basement of Hillhouse Avenue, 18 Yale students have spent the past 12 weeks transforming gears, wing nuts and sprockets into energy solutions for farmers working thousands of miles away in sub-Saharan Africa.

The class, called “Appropriate Technology for the Developing World,” was inspired by a trip that faculty member John Morrell took to Africa in 2009 with an international team of scientists, after learning that African farmers often earn just $1 to $2 a day. (more…)

Eighteen examples of the heaviest antiparticle ever found, the nucleus of antihelium-4, have been made in the STAR experiment at RHIC, the Relativistic Heavy Ion Collider at the U.S. Department of Energy’s Brookhaven National Laboratory.

“The STAR experiment is uniquely capable of finding antihelium‑4,” says the STAR experiment’s spokesperson, Nu Xu, of the Nuclear Science Division (NSD) at Lawrence Berkeley National Laboratory (Berkeley Lab). “STAR already holds the record for massive antiparticles, last year having identified the anti-hypertriton, which contains three constituent antiparticles. With four antinucleons, antihelium-4 is produced at a rate a thousand times lower yet. To identify the 18 examples required sifting through the debris of a billion gold-gold collisions.” (more…)

Multitasking Challenge: Radar Analysis of Walking Patterns Shows Promise for Detecting Concussions in Athletes and Soldiers

Walking and thinking at the same time can be especially difficult for persons who’ve suffered concussions, and scientists hope to use that multitasking challenge — measured by a simple radar system — to quickly screen individuals who may have suffered brain injuries. (more…)

Melting Ice on Arctic Islands a Major Player in Sea Level Rise

ANN ARBOR, Mich.— Melting glaciers and ice caps on Canadian Arctic islands play a much greater role in sea level rise than scientists previously thought, according to a new study led by a University of Michigan researcher.

The 550,000-square-mile Canadian Arctic Archipelago contains some 30,000 islands. Between 2004 and 2009, the region lost the equivalent of three-quarters of the water in Lake Erie, the study found. Warmer-than-usual temperatures in those years caused a rapid increase in the melting of glacier ice and snow, said Alex Gardner, a research fellow in the Department of Atmospheric, Oceanic and Space Sciences who led the project. The study is published online in Nature on April 20. (more…)
