Eidos plans to release the new “Lara Croft: The Angel of Darkness” video game this coming winter.

Agenda Set For Upcoming Planetary Defense Conference

February 26, 2007

The second Planetary Defense Conference will bring together scientists and engineers from the international space community on March 5 – 8 in Washington DC to assess our ability to discover and track near-Earth objects and deflect an asteroid or comet that poses a threat to Earth.

Agent-based computer models could anticipate future economic crisis

November 26, 2008

Researchers at the U.S. Department of Energy’s Argonne National Laboratory are trying to create new economic models that will provide policymakers with more realistic pictures of different types of markets so they can better avert future economic catastrophe.

They have created a new set of simulations called “agent-based models” to better anticipate how markets behave. These new models rely on information gleaned in part from surveys that ask respondents… read more

Agents of Change

September 7, 2004

Autonomous agents are still in the labs but could eventually play a critical role in areas ranging from setting market prices to creating more resilient networks.

Autonomous agents have the potential to become an extraordinarily powerful technology, with the capacity to learn, experiment and act independent of human control. Agents could ultimately improve productivity, increase software reliability and change the operation of markets, particularly supply chains.

Aggregators Attack Info Overload

August 19, 2003

A new breed of software, called newsreaders or aggregators, is helping manage information overload by allowing users to subscribe to feeds from diverse news sources and blogs.

‘Aggressive but safe’ SUV wins robotic street race

November 5, 2007

“Boss,” a vehicle developed at Carnegie Mellon University, was declared the winner of a $2 million prize in DARPA’s urban robot car race on Sunday.

It travelled autonomously through traffic for six hours and 60 miles around a ghost town in California.

The US military aims to create autonomous supply vehicles — with a goal of making a third of its supply fleet robotic by 2015 — to… read more

Aging and longevity tied to specific brain region in mice

Researchers watched two groups of mice, both nearing the end of a two-day fast. One group was quietly huddled together, but the other group was active and alert. The difference? The second set of mice had been engineered so their brains produced more SIRT1, a protein known to play a role in aging and longevity.

“This result surprised us,” says the study’s senior author Shin-ichiro Imai, MD, PhD, an… read more

Aging and the Insulin Pathway

April 8, 2001

New studies show that the insulin-signaling pathway that regulates aging in roundworms serves the same function in fruit flies and yeast.

By manipulating genes relating to insulin-like hormones, scientists were able to extend the lifespan of fruit flies by 85 percent and of yeast by three times.

“If we just could tap into the mammalian version of that system, it might be possible to retard or even reverse… read more

Aging Gracefully Requires Taking Out The Trash

December 20, 2007

Salk Institute scientists have found that boosting autophagy (self-cleaning) in the nervous system of fruit flies prevented the age-dependent accumulation of cellular damage in neurons and promoted longevity.

This research complements previous findings that suppressing autophagy can accelerate the accumulation of protein aggregates, which leads to neural degeneration.

Aging heart cells rejuvenated by modified stem cells

July 25, 2012


Damaged and aged heart tissue of older heart failure patients was rejuvenated by stem cells modified by scientists, according to research presented at the American Heart Association’s Basic Cardiovascular Sciences 2012 Scientific Sessions.

The research could one day lead to new treatments for heart failure patients, researchers said.

“Since patients with heart failure are normally elderly, their cardiac stem cells aren’t very healthy,” said… read more

Aging is recorded in our genes

genome-wide DNA methylation levels

Researchers at the Bellvitge Biomedical Research Institute in Barcelona, Spain have found a significantly higher amount of cytosine methylation in the newborn than in the centenarian: 80.5% of all cytosine nucleotides, compared with 73%.

Recent research suggests that changes in DNA methylation patterns as a person gets older may contribute to human diseases for which risk increases with age, including cancer.

DNA is made up of four… read more

Aging of eyes is blamed for range of health woes

February 22, 2012

The gradual yellowing of the lens and the narrowing of the pupil that occur with age disturb the body’s circadian rhythm, contributing to a range of health problems, these studies suggest. As the eyes age, less and less sunlight gets through the lens to reach key cells in the retina that regulate the body’s circadian rhythm, its internal clock.

Photoreceptive cells in the retina absorb sunlight and transmit

Aging, interrupted

The current pace of population aging is without parallel in human history but surprisingly little is known about the human aging process, because lifespans of eight decades or more make it difficult to study. Now, researchers at the Salk Institute for Biological Studies have replicated premature aging in the lab, allowing them to study aging-related disease in a dish.

In the February 23, 2011 advance online edition of the… read more

Agricultural robots may reduce costs of organic produce

September 20, 2012


Blue River Technology has announced $3.1 million in funding for its plans to develop agricultural robots that can automatically kill weeds and thin out plants like lettuce that need adequate room to grow, CNET reports.

It could help reduce the cost of organic produce.

The startup’s prototype Lettuce Bot uses a camera to image the plants beneath it. Machine learning algorithms then identify which ones are desirable and… read more

AI algorithm gives computers ‘hindsight’ to anticipate the future

April 15, 2011

An AI algorithm that gives computers “hindsight” to anticipate the future has been developed by computer scientists and economists at Tel Aviv University.

Funded by Google, the researchers have developed an algorithm that uses academic game theory to measure the distance between a desired outcome and an actual outcome. The algorithm can adapt to the situation at hand by analyzing the behavior of users as… read more
