Events in the future seem closer than those in the past

We tend to feel closer to the future because we feel like we’re moving toward it

Screen capture of a virtual environment for testing time perception (credit: Caruso E M et al./Psychological Science)

We say that time flies, it marches on, it flows like a river — our descriptions of time are closely linked to our experiences of moving through space.

Now, new research suggests that the illusions that influence how we perceive movement through space also influence our perception of time. The findings provide evidence that our experiences of space and time have even more in common than previously… read more

Using a handsfree kit or sending text messages is the same as being above the legal alcohol limit, an experiment by Scientists from  Australian universities in collaboration with the University of Barcelona has demonstrated.

The Australian universities of Wollongong, Victoria, Swinburne of Technology, the Institute for Breathing and Sleep, and the University of Barcelona measured the reaction capacity behind the wheel of 12 healthy volunteers who participated… read more

Playing video games for an hour each day can improve subsequent performance on cognitive tasks that use mental processes similar to those involved in the game, according to research published March 13 in the open-access journal PLOS ONE.

Previous evidence points to a causal link between playing action video games and enhanced cognition and perception. But what about the benefits of playing other types of video games?… read more

New results indicate that new particle is a Higgs boson

March 14, 2013

An example of simulated data modelled for the CMS particle detector on the Large Hadron Collider (LHC) at CERN. Here, following a collision of two protons, a Higgs boson is produced which decays into two jets of hadrons and two electrons. The lines represent the possible paths of particles produced by the proton-proton collision in the detector while the energy these particles deposit is shown in blue. (Image credit: CERN)

At the recent Moriond Conference, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) presented preliminary new results, finding that the new particle is looking more and more like a Higgs boson, the particle linked to the mechanism that gives mass to elementary particles.

It remains an open question, however, whether this is the Higgs… read more

Ultra-high-speed optical communications link sets new power efficiency record

March 14, 2013

optical communication link

Ultrafast supercomputers that operate at speeds 100 times faster than current systems may now be one step closer to reality.

A team of IBM researchers working on a U.S. Defense Advanced Research Projects Agency (DARPA)-funded program have found a way to transmit massive amounts of data with unprecedented low-power consumption. They increased the speed by 66 percent while cutting the power in half, compared to the previous… read more

University of Toronto scientists have found evidence that stimulating the brain using repetitive transcranial magnetic stimulation (rTMS) may be an effective strategy to improve cognitive function for patients with schizophrenia.

“In a randomized controlled trial, we evaluated whether rTMS can improve working memory in schizophrenia,” said Dr. Mera Barr and senior author Dr. Zafiris Daskalakis. “Our results showed that rTMS resulted in a significant improvement in working… read more

Astronomers conduct first remote reconnaissance of another solar system

New imaging tools penetrate bright starlight to image planets; could help identify candidate habitable planets for 100YSS expedition
March 14, 2013

Image of the HR8799 planets with starlight optically suppressed and data processing conducted to remove residual starlight. The star is at the center of the blackened circle in the image. The four spots indicated with the letters b through e are the planets. This is a composite image using 30 wavelengths of light and was obtained over a period of 1.25 hours on June 14 and 15, 2012.

Researchers have conducted a remote reconnaissance of a distant solar system with a new telescope imaging system that sifts through the blinding light of stars.

Using a suite of high-tech instrumentation and software called Project 1640, the scientists collected the first chemical fingerprints, or spectra, of this system’s four red exoplanets, which orbit a star 128 light years away from Earth.

A detailed description of the… read more

The number of potentially habitable planets in our galaxy is greater than previously thought, according to a  new analysis by a Penn State researcher, and some of those planets are likely lurking around nearby stars.

“We now estimate that if we were to look at 10 of the nearest small stars we would find about four potentially habitable planets,” said Ravi Kopparapu, an Evan… read more

A pair of stars in the third-closest star system to the Sun has been discovered by an astronomer —  the closest star system discovered since 1916.

The discovery was made by Kevin Luhman, an associate professor of astronomy and astrophysics at Penn State University and a researcher in Penn State’s Center for Exoplanets and Habitable Worlds.

The star system,  named “WISE J104915.57-531906″ (discovered in a map by… read more

Untangling life’s origins

The "Big Bang" of protein evolution
March 13, 2013

protein_topologies_optimization

Researchers in the Evolutionary Bioinformatics Laboratory at the University of Illinois in collaboration with German scientists have been using bioinformatics techniques to probe the world of proteins for answers to questions about the origins of life.

Proteins are formed from chains of amino acids and fold into three-dimensional structures that determine their function. According to crop sciences professor Gustavo Caetano-Anollés, very little is known about… read more

At a panel discussion at SXSW Monday, Defense Distributed (DEFCAD) founder Cody Wilson unveiled that DEFCAD is working on plans to expand its efforts beyond just firearms to any controversial object users feel like uploading, including grenades and patented ones, VentureBeat reports.

Cody:
Can 3D printing be subversive? If it can, it will be because it allows us to make the important things — not trinkets, not lawn gnomes,… read more

Research from the University of Maryland School of Medicine has revealed key features in proteins needed for life to function on Mars and other extreme environments.

The researchers, funded by NASA, studied organisms that survive in the extreme environment of Antarctica.

They found subtle but significant differences between the core proteins in ordinary organisms and Haloarchaea, organisms that can tolerate severe conditions such as… read more

viral search

At Microsoft Research’s annual technology demo day this week, researchers showed off a tool called Viral Search that attempts to measure virality in its more literal sense. That means not overall traffic over time, but the mechanics by which it passes from person to person over many generations, MIT Technology Review reports.

The software looked at 1.4 billion Tweets over the course of a year… read more
