Berkeley Lab scientists create nanoparticle probes that may lead to a better understanding of diseases
Imagine tracking a deer through a forest by clipping a radio transmitter to its ear and monitoring the deer’s location remotely. Now imagine that transmitter is the size of a house, and you understand the problem researchers may encounter when they try to use nanoparticles to track proteins in live cells. (more…)
In an effort to identify the underlying causes of neurological disorders that impair motor functions such as walking and breathing, UCLA researchers have developed a novel system to measure communication between stem cell–derived motor neurons and muscle cells in a Petri dish.
The study provides an important proof of principle that functional motor circuits can be created outside the body using these neurons and cells and that the level of communication, or synaptic activity, between them can be accurately measured by stimulating the motor neurons with an electrode and then tracking the transfer of electrical activity into the muscle cells to which the neurons are connected.

Analytics Software Enhances Insurer’s Ability to Resolve Claims Faster
Johannesburg, South Africa – 09 May 2012: IBM today announced that Santam, South Africa’s leading short term insurance company, has saved $2.4 million on fraudulent claims in the first four months of using IBM business analytics software. The analytics software has enhanced Santam’s fraud detection capabilities and also enabled faster payouts for legitimate claims.
“IBM and OLRAC-SPSolutions have helped us build a solution that has not only transformed our claims processing methodology in terms of speed and efficiency, but also provides new insight which helps us identify false claims more quickly, which protects our business and customers,” said Anesh Govender, Head of Finance, Reporting and Salvage at Santam. “The solution has delivered a full return on investment and also helped uncover a motor insurance fraud syndicate in less than 30 days after the system went live.” (more…)
COLUMBUS, Ohio – When you “lose yourself” inside the world of a fictional character while reading a story, you may actually end up changing your own behavior and thoughts to match that of the character, a new study suggests.
Researchers at Ohio State University examined what happened to people who, while reading a fictional story, found themselves feeling the emotions, thoughts, beliefs and internal responses of one of the characters as if they were their own – a phenomenon the researchers call “experience-taking.” (more…)
PASADENA, Calif. – NASA’s Spitzer Space Telescope has detected light emanating from a “super-Earth” planet beyond our solar system for the first time. While the planet is not habitable, the detection is a historic step toward the eventual search for signs of life on other planets.
“Spitzer has amazed us yet again,” said Bill Danchi, Spitzer program scientist at NASA Headquarters in Washington. “The spacecraft is pioneering the study of atmospheres of distant planets and paving the way for NASA’s upcoming James Webb Space Telescope to apply a similar technique on potentially habitable planets.” (more…)
Battles of sexes shown to spur adaptive sex differences
Sex differences account for some of the most of the spectacular traits in nature: the wild colours of male guppies, the plumage of peacocks, tusks on walruses and antlers on moose. Sexual conflict – the battle between males and females over mating – is thought to be a particularly potent force in driving the evolution of traits that differ in males and females.
However, the genetic processes responsible for producing such traits are not well understood, nor how they evolved from their simpler less elaborate ancestral forms. We tend to assume that each tiny step in evolution is an advantage. But are they really? (more…)
