Hod Lipson, an associate professor and the director of the Creative Machines Lab at Cornell, said “3D printing is worming its way into almost every industry, from entertainment, to food, to bio- and medical-applications,” The New York Times reports.

Dr. Lipson, the co-author of “Fabricated: The New World of 3D Printing,” said… read more

Civilization faces ‘perfect storm of ecological and social problems’

Celebrated scientists and development thinkers today warn that civilization is faced with a perfect storm of ecological and social problems driven by overpopulation, overconsumption, and environmentally malign technologies.

In the face of an “absolutely unprecedented emergency,” say the 18 past winners of the Blue Planet prize — the unofficial Nobel for the environment — society has “no choice but to take dramatic action to avert a collapse of civilisation. Either we… read more

Groups concerned over arming of domestic drones

Chief Deputy Randy McDaniel of the Montgomery County Sheriff’s Office in Texas said his department is considering using rubber bullets and tear gas on its drone, CBS DC reports.

“Drone manufacturers are also considering offering police the option of arming these remote-controlled aircraft with (nonlethal for now) weapons like rubber bullets, Tasers, and tear gas,” the ACLU says on their website.

Could we build a 20-kilometer-high space tower?

September 12, 2012

Science-fiction novelist Neal Stephenson imagines a 20-kilometer-high steel tower that reaches into the stratosphere.

From that height, planes could save fuel by docking at the tower rather than landing, and space missions could do the same by launching from it.

Stephenson is teaming up with a structural engineer, Keith Hjelmstad at Arizona State University (ASU), to work out how to actually build the tower, New Scientist reports.… read more

2045: The Year Man Becomes Immortal

February 10, 2011

Time magazine just published a comprehensive cover story on the Singularity and Ray Kurzweil’s “radical vision for humanity’s immortal future.”

“Kurzweil’s interest in humanity’s cyborganic destiny began about 1980 largely as a practical matter. He needed ways to measure and track the pace of technological progress…(Kurzweil) has been publishing his thoughts about the future of human and machine-kind for 20 years, most recently in The Singularity Isread more

Scientists discover how to slow down aging in mice and increase longevity

Scientists at Albert Einstein College of Medicine of Yeshiva University have found that the hypothalamus of mice controls aging throughout the body.

Their discovery of a specific age-related signaling pathway opens up new strategies for combating diseases of old age and extending lifespan.

Background: the hypothalmus and inflammation

“Scientists have long wondered whether aging occurs independently in the body’s various tissues or if it… read more

The future of education eliminates the classroom, because the world is your class

Technology can turn our entire lives into learning experiences via “socialstructed learning,” an aggregation of microlearning experiences drawn from a rich ecology of content and driven not by grades but by social and intrinsic rewards, suggests Marina Gorbis, Executive Director at the Institute for the Future, in Fast Company.

“Today’s obsession with MOOCs is a reminder of the old forecasting paradigm: In the early stages of technology… read more

Teleporting information achieved by TU Delft

A key step toward a "quantum internet"

Teleporting people through space, as in Star Trek, is impossible by the laws of physics, but researchers at TU Delft‘s Kavli Institute of Nanoscience have succeeded in teleporting information.

Using quantum entanglement, they transferred the information contained in a quantum bit in a diamond to a quantum bit in another diamond three meters away, without the information having traveled through the intervening space.

Texas wind farms increase land surface temperature

May 2, 2012

Wind Farm

A Texas region containing four of the world’s largest wind farms showed an increase in land surface temperature over nine years that researchers have connected to local meteorological effects of the turbines.

The land surface temperature around the west-central Texas wind farms warmed at a rate of .72 degrees Celsius per decade during the study period relative to nearby regions without wind farms, an effect most likely… read more

Morality for robots?

September 5, 2012

machine-question-book

In new book, NIU Northern Illinois University Professor David Gunkel examines ethical questions raised by 21st century computers, robots and artificial intelligence.

On the topic of computers, artificial intelligence and robots,  he says science fiction is fast becoming “science fact.”

Fictional depictions of artificial intelligence have run the gamut from the loyal Robot in “Lost in Space” to the killer computer HAL in “2001:… read more

How the brain ‘takes out the trash’ while we sleep

October 18, 2013

cerebral_spinal_fluid

A new study shows that a recently discovered system that flushes waste from the brain is primarily active during sleep, giving fresh meaning to the old adage that a good night’s sleep clears the mind.

This revelation could transform scientists’ understanding of the biological purpose of sleep and point to new ways to treat neurological disorders.

“This study shows that the brain has different functional states… read more

Neuroscientists find cortical columns in brain not uniform, challenging large-scale simulation models

Despite a long-held scientific belief that cortex is built up by repeatedly occurring elementary units called cortical columns, a new study by neuroscientists has found that the structure of the brain’s cortical columns can largely deviate within individual animals, and even within a specific cortical area.

The study also found that these structural differences are not arbitrary, but reflect organizational and functional properties of the… read more

Astronomers have discovered a distant quasar illuminating a vast nebula of diffuse gas, revealing, for the first time, part of the network of filaments thought to connect galaxies in a cosmic web.

Researchers at the University of California, Santa Cruz led the study, published January 19 in Nature.

Using the 10-meter Keck I Telescope at the W. M. Keck Observatory in Hawaii, the researchers detected a… read more

Harvard scientists to build Iron Man-like suit for military

July 26, 2012

Harvard University scientists are working on an Iron Man-like smart suit that could improve soldiers’ endurance in war zones, Network World reports.

The university received a $2.6 million research grant for the project from DARPA.

The suit, which is expected to include sensors and its own energy source, will be designed to delay the onset of fatigue, enabling soldiers to travel further in the field, while… read more
