At last: a low-cost, professional-grade light-based 3D printer

September 27, 2012


Formlabs’ new Form 1 3D printer could bring professional-grade 3-D prints to the home workshop.

Desktop 3-D printing has largely been the domain of extrusion-based machines like MakerBot’s Replicator and homebrew RepRap designs.

These lag behind the capabilities of pricier, professional stereolithography devices, where UV light cures incredibly thin layers of resin to create objects on par with manufactured goods.

Developing this type of printer at a… read more

US State Dept. orders removal of 3D-printed gun designs

May 10, 2013


The U.S. State Department has demanded designs by Defense Distributed for a 3D-printed gun be taken offline because publishing them online may breach arms-control regulations, Forbes reports.

The order to remove the blueprints for the plastic gun comes after they were downloaded more than 100,000 times.

However, the files were actually being served by Mega, the New Zealand-based storage service created by ex-hacker entrepreneur Kim… read more

Existing cropland could feed 4 billion more

An abundant supply of food for a hungry world, hidden in plain sight
August 5, 2013


Reallocating croplands away from fuels and animal feed could boost food available for people by 70 percent without clearing more land, new research from the Institute on the Environment at the University of Minnesota research shows

The world’s croplands could feed 4 billion more people than they do now just by shifting from producing animal feed and biofuels to producing exclusively food for human consumption,… read more

NSA admits wrongly adding 16,000 phone numbers to ‘alert list’

First map of how the brain organizes everything we see

December 20, 2012


How do we make sense of the thousands of images that flood our retinas each day? Scientists at the University of California, Berkeley, have found that the brain is wired to organize all the categories of objects and actions that we see, and they have created the first interactive map of how the brain organizes these groupings.

How to lose 50 years of aging in 16 days

January 3, 2013


Attention seniors: French scientists have developed a process that permanently dyes white hair without harmful chemicals.

Philippe Walter and colleagues soaked white hairs in a solution containing fluorescent gold nanoparticles.

The hairs turned pale yellow and then darkened to a deep brown. The color remained even after repeated washings.

Using an electron microscope, the scientists confirmed that the particles were forming inside the hairs’ central core cortex.… read more

A research team from The Scripps Research Institute (TSRI), Mayo Clinic and other institutions has identified a new class of drugs that in animal models dramatically slows the aging process, alleviating symptoms of frailty, improving cardiac function, and extending a healthy lifespan.

They found two drugs — the cancer drug dasatinib (sold under the trade name Sprycel) and quercetin, a natural compound found… read more

The more science you know, the less worried you are about climate

May 30, 2012


Americans with higher levels of scientific and mathematical knowledge are more skeptical regarding the dangers of climate change than their more poorly educated fellow citizens, a U.S. National Science Foundation-funded study has found.

The results of the survey are especially remarkable as the researchers were doing so from the position that the “scientific consensus” (carbon-driven global warming is ongoing and extremely dangerous) is a settled fact, and the priority is… read more

University of Southampton researchers have discovered a novel way of killing cancer cells by leaves healthy cells undamaged, unlike traditional therapies such as radiotherapy.

Chris Proud, Professor of Cellular Regulation in Biological Sciences at the University of Southampton says: “Cancer cells grow and divide much more rapidly than normal cells, meaning they have a much higher demand for and are often starved of, nutrients and… read more

Worldwide annual solar PV installations will double by 2020, says report
