Two newly published studies by a team of Brown University researchers provide ample new evidence that the reason coastal saltmarshes are dying from Long Island to Cape Cod is that hungry crabs, left unchecked by a lack of predators, are eating the cordgrass. (See sidebar on marsh die-off and greenhouse gasses.)
PROVIDENCE, R.I. [Brown University] — A marathon summer of field work by Mark Bertness, professor of ecology and evolutionary biology, and a squadron of students may finally help settle the heated debate about what’s killing the coastal saltmarshes of southern New England and Long Island. The group’s work has yielded two new papers that offer clear evidence of the cause. (more…)
Mercury was long thought to be lacking volatile compounds that cause explosive volcanism. That view started to change when the MESSENGER spacecraft returned pictures of pyroclastic deposits — the telltale signature of volcanic explosions. Now more detailed data from MESSENGER shows that volcanoes exploded on Mercury for a substantial portion of the planet’s history. The findings suggest Mercury not only had volatiles but held on to them for longer than scientists had expected.
PROVIDENCE, R.I. [Brown University] — The surface of Mercury crackled with volcanic explosions for extended periods of the planet’s history, according to a new analysis led by researchers at Brown University. The findings are surprising considering Mercury wasn’t supposed to have explosive volcanism in the first place, and they could have implications for understanding how Mercury formed. (more…)
Research also helps unravel the mystery of retreating glaciers in the Pacific Ocean’s western tropics
Using a cutting-edge research technique, UCLA researchers have reconstructed the temperature history of a region that plays a major role in determining climate around the world.
The findings, published online Feb. 27 in the journal Nature Geoscience, will help inform scientists about the processes influencing global warming in the western tropical Pacific Ocean. (more…)
Over the last three decades U.S. parents have committed filicide — the killing of one’s child — about 3,000 times every year. The horrifying instances are often poorly understood, but a recent study provides the first comprehensive statistical overview of the tragic phenomenon. The authors also suggest underlying hypotheses of motives with the hope of spurring research on filicide prevention.
PROVIDENCE, R.I. [Brown University] — Instances in which parents kill their children may seem so horrifying and tragic that they defy explanation. Published scientific and medical research, meanwhile, doesn’t offer much epidemiological context to help people understand patterns among such heinous crimes. A paper in the March edition of the journal Forensic Science International provides the first comprehensive statistical analysis of filicide in the United States, drawing on 32 years of data on more than 94,000 arrests. The study also explores possible underlying psychiatric and biological underpinnings of filicide. (more…)
A new drug, called pritelivir, may offer a new treatment option for patients with genital herpes, a new industry-sponsored – study led by University of Washington researchers has found.
The study appears in this week’s issue of the New England Journal of Medicine. The lead author is Anna Wald, M.D., professor of medicine, epidemiology, and laboratory medicine, and medical director at the Virology Research Clinic at the University of Washington. Other UW coauthors include Dr. Amalia Magaret, Dr. Christine Johnston, Dr. Lawrence Corey, Dr. Meei-Li Huang and Stacy Selke. (more…)
Researchers have discovered well-preserved pelves and a partial pelvic fin from Tiktaalik roseae, a 375 million-year-old transitional species between fish and the first legged animals, which reveal that the evolution of hind legs actually began as enhanced hind fins. This challenges existing theory that large, mobile hind appendages were developed only after vertebrates transitioned to land.
The scientists describe the fossils in the Proceedings of the National Academy of Sciences, online on Jan. 13. The piece marks the inaugural article for Prof. Neil Shubin, Robert R. Bensley Distinguished Service Professor of Organismal Biology and Anatomy, as a member of the National Academy of Sciences. (more…)
Builds a Massive Network of Local Cloud Hubs for Businesses Worldwide with 40 Data Centers Across Five Continents
ARMONK, N.Y. – 17 Jan 2014: IBM today announced plans to commit over $1.2 billion to significantly expand its global cloud footprint. This investment includes a network of cloud centers designed to bring clients greater flexibility, transparency and control over how they manage their data, run their business and deploy their IT operations locally in the cloud.
This year IBM plans to deliver cloud services from 40 data centers worldwide in 15 countries and five continents globally, including North America, South America, Europe, Asia and Australia. IBM will open 15 new centers worldwide adding to the existing global footprint of 13 global data centers from SoftLayer and 12 from IBM. Among the newest data centers to launch are China, Washington, D.C., Hong Kong, London, Japan, India, Canada, Mexico City and Dallas. With this announcement, IBM plans to have data centers in all major geographies and financial centers with plans to expand in the Middle East and Africa in 2015. (more…)
AUSTIN, Texas — As coastal communities continue to rebuild in the wake of Hurricane Sandy, scientists at last week’s annual meeting of the American Geophysical Union offer some encouraging news: The storm did not seriously damage the offshore barrier system that controls erosion on Long Island. Long-term concerns remain about the effects on the region of sea-level rise, pollutants churned up by the storm within back-barrier estuaries, and the damage closer to shore, but in the near-term, Long Island residents can rebuild knowing that Hurricane Sandy did not significantly alter the offshore barrier systems that control coastal erosion on the island.
