Threading the Climate Needle: The Agulhas Current System

*Increased Agulhas “leakage” significant player in global climate variability*

The Agulhas Current which runs along the east coast of Africa may not be as well known as its counterpart in the Atlantic, the Gulf Stream. But now researchers are taking a closer look at this current and its “leakage” from the Indian Ocean into the Atlantic Ocean–and what that may mean for climate change.

In results of a study published in this week’s issue of the journal Nature, a team of scientists led by University of Miami Rosenstiel School of Marine & Atmospheric Science Oceanographer Lisa Beal, suggests that Agulhas leakage could be a significant player in global climate variability. (more…)

Q&A: Creating a Safe Haven For Children

General, Health

For over 25 years, Dr. John M. Leventhal has been fighting a battle to protect the lives of hundreds of children who come through one of the child abuse programs at Yale.

He has won many struggles along the way, but to win the war, he says, the program needs to be armed with more state and federal support, as well as support from individuals and foundations.

“Finding ways to protect children who can’t defend themselves is part of what wakes me up in the morning and motivates me to continue this tough, but important work,” says Leventhal, professor of pediatrics at Yale School of Medicine and director of the Child Abuse Programs at Yale-New Haven Children’s Hospital.

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

Nature, Science

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…)

Harmonic Convergence: Music and Social Networking Join Forces

Technology

*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

Science

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…)

Anti-Helium Discovered in the Heart of STAR

Science

*Berkeley Lab nuclear scientists join with their international colleagues in the latest record-breaking discovery at RHIC*

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

Science

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…)
