Scientists Use PET to Predict Increased Survival in Cancer Patients After First Chemo Cycle

Researchers from UCLA’s Jonsson Comprehensive Cancer Center have found that by administering a PET scan to individuals with soft-tissue sarcomas after just a single cycle of neoadjuvant chemotherapy, they can predict increased survival in these patients.

Prior research by this multidisciplinary team of physician-scientists had shown that a combined PET/CT scan using a glucose uptake probe called FDG allowed them to determine the pathologic response of patients’ tumors after the first dose of chemotherapy drugs. They then wondered if the patients who showed a significant PET response after the first round of chemotherapy also were surviving longer. (more…)

Transactional Memory: An Idea Ahead of Its Time

Nearly 20 years ago, two Brown University computer scientists were working on a largely theoretical problem: How could multiple parallel processors make changes to shared resources safely and efficiently? Their proposal — transactional memory — is sparking fresh interest as a new generation of processors seeks improved power and speed.

In 1993, Maurice Herlihy and a colleague published a paper on transactional memory — a new, clever tactic in computing to deal with handling shared revisions to information seamlessly and concurrently. Few noticed.

Nearly 20 years later, transactional memory is an idea that’s now the rage in hardware computing, and Herlihy, computer science professor at Brown University, has morphed into a prophet of sorts, a computing pioneer who was far ahead of his time. Intel recently announced that transactional memory will be included in its mainstream “Haswell” hardware architecture by next year. IBM has adopted transactional memory in the Blue Gene/Q supercomputer. The original paper by Herlihy and Eliot Moss has been cited more than 1,300 times. (more…)

The Weird World of “Remote Heating”

UMD Researchers Discover Nanoscale Phenomena with Potential for Computer Speed Advances

College Park, Md.– A team of University of Maryland scientists have discovered that when electric current is run through carbon nanotubes, objects nearby heat up while the nanotubes themselves stay cool, like a toaster that burns bread without getting hot. Understanding this completely unexpected new phenomenon could lead to new ways of building computer processors that can run at higher speeds without overheating. (more…)

Release of New 4G Phones a Milestone for Windows Phone, Nokia Partnership

*AT&T today launched two new 4G LTE-capable Windows Phones – the sleek, award-winning Nokia Lumia 900 and the HTC Titan II. The launch is an important milestone for partners Microsoft and Nokia, and an AT&T spokesman said the Lumia 900 will be a centerpiece of its spring advertising campaign.*

REDMOND, Wash. – April 9, 2012 – AT&T today launched two new devices, the Nokia Lumia 900 and the HTC Titan II, the first Windows Phones available on the mobile operator’s speedy 4G long-term evolution (LTE) network.

The launch is a milestone for Microsoft and partner Nokia, and also for AT&T, which is giving the award-winning Lumia 900 top billing as one of the centerpieces of its spring retail and marketing campaign. (more…)

IBM and ZSE Create Virtual Green Highway for Electric Vehicles

*E-Mobility Project Identifies EV Charging Station Options between Two Cities*

Armonk, NY and Slovakia – 09 Apr 2012: IBM today announced it has teamed with Západoslovenská energetika, a.s. (ZSE), the largest distributor and supplier of electricity in Slovakia, on a smart energy “feasibility” study that will help prepare the capital city Bratislava for electric vehicles (EVs).

Using e-mobility technology, the study will help identify the possibilities of connecting two neighboring metropolitan areas – Bratislava, Slovakia and Vienna, Austria with a “green” highway. This highway will interconnect the two cities with a network of public charging stations for electric vehicles. (more…)

Which Plants Will Survive Droughts, Climate Change?

New research by UCLA life scientists could lead to predictions of which plant species will escape extinction from climate change.

Droughts are worsening around the world, posing a great challenge to plants in all ecosystems, said Lawren Sack, a UCLA professor of ecology and evolutionary biology and senior author of the research. Scientists have debated for more than a century how to predict which species are most vulnerable.

Sack and two members of his laboratory have made a fundamental discovery that resolves this debate and allows for the prediction of how diverse plant species and vegetation types worldwide will tolerate drought, which is critical given the threats posed by climate change, he said. (more…)

Internet Use Promotes Democracy Best in Countries That Are Already Partially Free

COLUMBUS, Ohio — Although use of the internet has been credited with helping spur democratic revolutions in the Arab world and elsewhere, a new multinational study suggests the internet is most likely to play a role only in specific situations.

Researchers at Ohio State University found that the internet spurs pro-democratic attitudes most in countries that already have introduced some reforms in that direction. (more…)
