The super-massive black hole at the center of the Milky Way Galaxy has a healthy appetite, frequently snacking on asteroids and comets. Now, a cloud of gas and dust called G2 is on a dangerous course to become its next meal.
Even though Sagittarius A* (pronounced “Sagittarius A-star”) hasn’t been easy to see through the cosmic dust, sitting 25,000 light years away at galaxy central, scientists know it is a black hole — and a hungry one at that. Its weight has been estimated to be more than that of 4 million suns. (more…)
TORONTO, ON – A new study published by the Social Science Research journal reveals that second-generation Chinese and South Asian immigrants in the US, Canada, and Australia are more successful than the respective mainstream populations (third- and higher-generation whites).
Jeffrey G. Reitz and Naoko Hawkins from the University of Toronto and Heather Zhang from McGill University examined survey and census data from these countries to compare the achievements of immigrants and their offspring. (more…)
Young technologists are looking to take the world by storm this weekend at the Imagine Cup 2012 Worldwide Finals in Sydney, Australia.
SYDNEY – Wrapped in the flags of their countries, the competitors climb onto the podium, beaming with joy as the cameras flash. They are young, passionate, business-savvy ambassadors of their field.
These aren’t soccer players or high jumpers, but they are no less competitors than the athletes seeking gold medals at the 2012 Summer Games in London. They are the planet’s premiere young technologists. And, to slightly alter an infamous movie line, they’ve come to change the world and chew bubblegum – and they’re all out of bubblegum. (more…)
Heading into the U.S. national finals, Microsoft’s signature technology competition has reached 1.25 million students worldwide over the past 10 years.
REDMOND, Wash. — April 20, 2012 — Across every industry — from healthcare to transportation and agriculture to infrastructure — the world has a never-ending need for inspired minds to find creative solutions that solve tough challenges. Yet it’s been estimated that 1 million science and engineering jobs will go unfilled in the U.S. alone over the next three to five years.
According to Mark Hindsbo, vice president of Microsoft’s U.S. Developer & Platform Evangelism Group, that’s why programs like the Imagine Cup are so important. Encouraging students to develop technology-based solutions for real-world issues, and inspiring them to pursue careers in science, technology, engineering and mathematics, has been the mission of Microsoft’s signature technology competition for the past decade. Hindsbo has been involved with the competition since its beginnings. Every year, he says, the judges are amazed by the contestants’ projects and enthusiasm. (more…)
Massive detector homes in on cosmic ray production
IceCube, an international collaboration involving University of Delaware scientists, is shedding new light on cosmic ray production.
Although cosmic rays were discovered 100 years ago, their origin remains one of the most enduring mysteries in physics. Now, the IceCube Neutrino Observatory, a massive detector in Antarctica, is homing in on how the highest energy cosmic rays are produced. (more…)
*UCLA-launched partnership identifies genes that boost or lessen risk of brain atrophy, mental illness, Alzheimer’s disease*
In the world’s largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain’s resistance to a variety of mental illnesses and Alzheimer’s disease.
Published April 15 in the advance online edition of the journal Nature Genetics, the study also uncovers new genes that may explain individual differences in brain size and intelligence. (more…)
EAST LANSING, Mich. — The huge changes in the Earth’s crust that influenced human evolution are being redefined, according to research published today in Nature Geoscience.
The Great Rift Valley of East Africa – the birthplace of the human species – may have taken much longer to develop than previously believed.
“We now believe that the western portion of the rift formed about 25 million years ago, and is approximately as old as the eastern part, instead of much younger as other studies have maintained,” said Michael Gottfried, Michigan State University associate professor of geological sciences. “The significance is that the Rift Valley is the setting for the most crucial steps in primate and ultimately human evolution, and our study has major implications for the environmental and landscape changes that form the backdrop for that evolutionary story.” (more…)
Conventional wisdom holds that during the Mesozoic Era, mammals were small creatures that held on at life’s edges. But at least one mammal group, rodent-like creatures called multituberculates, actually flourished during the last 20 million years of the dinosaurs’ reign and survived their extinction 66 million years ago.
New research led by a University of Washington paleontologist suggests that the multituberculates did so well in part because they developed numerous tubercles (bumps, or cusps) on their back teeth that allowed them to feed largely on angiosperms, flowering plants that were just becoming commonplace.
