The U.S. should create a new agency dedicated to manned exploration of the moon, Mars and other destinations in deep space, says former Apollo astronaut Harrison Schmitt, Space.com reports.

Schmitt suggests the new agency be called the National Space Exploration Administration.

The new deep-space agency should “stay young, and develop a management structure that is not so hierarchical — that is actually a… read more

Multi-material 3D printer creates realistic neurosurgical models for training

December 12, 2013

A perforator creates a burr hole in the model of a skull. The model, produced using a multimaterial 3D printer, is composed of a variety of materials that simulate the various consistencies and densities of human tissues encountered during neurosurgery.

Researchers* from Malaysia and the UK have used a new multi-material 3D printer to create realistic, low-cost model of the skull for use by students in practicing neurosurgical techniques.

The model uses a variety of materials that simulate the various consistencies and densities of human tissues encountered during neurosurgery.

Neurosurgery is a difficult discipline to master. Trainees may spend as many as 10 years after graduation from medical… read more

Five potential habitable exoplanets now

Exoplanet Gliese 581g is the best candidate so far of a potential habitable exoplanet

Gliese 581g

New data suggests the exoplanet Gliese 581g is the best candidate so far of a potential habitable exoplanet. The nearby star Gliese 581 — located about 20 light years away from Earth in the constellation Libra — has four planets; the outermost planet, Gliese 581d, was already suspected habitable.

This will be the first evidence for any two potential habitable exoplanets that are orbiting the same star.

Is this Elon Musk’s secret design for a high-speed train?

July 16, 2013

Hyperloop2

Elon Musk has been hinting at an idea he calls the Hyperloop — a ground-based transportation technology that would get people from Los Angeles to San Francisco in under half an hour, for less than 1/10 the cost of California’s $69 billion plan.

On Monday, Musk tweeted that he will publish an “alpha design” for the Hyperloop by Aug. 12. As Slateread more

3D printing lowers environmental impact, says study

October 5, 2013

3d_printed_blocks_large

Making things at home on a 3D printer uses less energy — and therefore releases less carbon dioxide — than producing it in a factory and shipping it to a warehouse.

That’s according to a study led by Joshua Pearce, an associate professor of materials science and engineering/electrical and computer engineering at Michigan Technological University.

The team conducted life-cycle impact analyses on three products:… read more

Researchers at Bell Labs in New Jersey say they’ve used compressive sensing to build a camera that needs no lens and uses only a single sensing pixel to take photographs, MIT Technology Review reports.

What’s more, the images from this camera are never out of focus.

The invention could revolutionize optical, infrared and millimeter-wave imaging

This revolutionary lensless camera has a number of advantages over… read more

Taking 3D printing into the metal age

October 16, 2013

The European Space Agency (ESA)and the EU, together with industrial and educational partners, are developing the first large-scale production methods to 3D-print complex 3D-printed parts made of metal that can withstand temperatures at 1000°C — fit for space and the most demanding applications on Earth.

3D printers are expected to revolutionize the way we live but until recently they could work with only plastic, which… read more

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

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

(NASA MSFC, Artist Pat Rawling)

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

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

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
