Before the mid-1950s, polio was one of the most feared diseases in the world. Caused by a virus, it created annual epidemics. The disease hit children the hardest. Once contracted, the virus replicates rapidly and invades the nervous system of the victim. People infected are generally contagious for six weeks, even if they show no symptoms

The disease struck indiscriminately. Even U.S. President Franklin D. Roosevelt was affected, losing the use of his legs after a diagnosis at the age of 39. In 1938, he founded the National Foundation for Infantile Paralysis, to fund research into a cure. Roosevelt also founded the March of Dimes, a massive public fundraising effort to aid the afflicted and find a cure or vaccine Read more…

This Might Be the Strongest AND Lightest Material Ever Seen in 3D Printing

This Might Be the Strongest AND Lightest Material Ever Seen in 3D Printing

By Tyler Koslow

One of the most scientifically mind-blowing materials ever discovered, graphene (an allotrope of carbon) has been praised for having an unbelievable combination of material characteristics, including low density, top-notch mechanical properties, thermal stability, and even electrical conductivity. In fact, graphene aerogel is one of the lightest materials ever discovered, reportedly weighing seven times less than air…But these great qualities only really hold true in graphene’s original 2D material composition, which are greatly diminished when graphene is made three-dimensional. That is until now.…

Humans are not the only animals into video games, it turns out.

In a research project that began Monday, orangutans at Australia’s Melbourne Zoo are being entertained with interactive projections from an Xbox Kinect, a motion sensing device built for the gaming console. According to an emailed statement from Microsoft, which designed the device, the experiment is focused on how the creatures learn and interact with technology.

The project is a world first, say researchers from Zoos Victoria and the University of Melbourne’s Microsoft Research Centre for Social Natural User Interfaces Read more…

You know the stories about how close Nobel Prize-winning physicist Erwin Schrödinger came to never marrying? Chances are you haven’t heard them, because nobody ever talks about Schrödinger’s marriage when they discuss his work.

The same can’t be said for female scientists, however. Twitter user Daurmith jumped on this by writing short bios for some of science’s most famous men, but in the condescending manner typically employed for female scientists

This meant putting all the focus on the scientists’ family lives, their looks and the sheer amazement that they were so brilliant despite being men Read more…

By simply being in the right place at the right time, scientists have captured photos of an extremely remote sub-Antarctic volcano erupting.

The Big Ben volcano, found on Heard Island, is one of only two active volcanoes in Australia’s territories. The other is on one of the McDonald Islands. Both islands are far from any inhabited land — they are 4,000 kilometres (2,485 miles) southwest of mainland Australia in the Southern Ocean — and although they are known to have erupted before, they have rarely been sighted except by satellite

Prof. Pearce’s “Open-Source Lab” Unleashes the Power of 3D Printed Lab Equipment

Prof. Pearce’s “Open-Source Lab” Unleashes the Power of 3D Printed Lab Equipment

By Davide Sher

At 3DPI, we have had the opportunity to interview Professor Joshua Pearce from Michigan Tech a few times. That’s because he represents some of concepts that many 3D printer adopters appreciate and like to promote, in particular the use of low-cost 3D printing and other open source technologies directed toward sustainability, innovation, and discovery.
Many times, I have found myself quoting Prof. Pearce’s study on the savings derived from a single open source, 3D printed mechanical pump to exemplify the benefits of 3D printing in general.…

Doomsday

Feed-twFeed-fb

Scientists behind a “Doomsday Clock” that measures the likelihood of a global cataclysm are set to announce Tuesday whether civilization is any closer or farther from disaster.

The Bulletin of the Atomic Scientists is expected to unveil the minute hand on the metaphorical clock in Washington, D.C. The clock reflects how vulnerable the world is to catastrophe from nuclear weapons, climate change and new technologies, according to the bulletin.

They will reveal the new time at 1:30 p.m. ET on Tuesday. You can watch it live here.

California Gov. Jerry Brown will join former U.S. Secretary of State George Shultz and former U.S. Secretary of Defense William Perry for a discussion at Stanford University after the unveiling. Read more…

A major, potentially life-threatening winter storm could bring feet of snow to millions of people living along the east coast of the United States starting Friday.

Forecasters have issued a blizzard warning for Washington, D.C., and blizzard watches for New York City, Philadelphia and other cities along a swath of the coast. It’s also possible that the storm could cause coastal flooding and bring power outages to some areas along its path, possibly leaving people without power for hours or days

According to the National Weather Service, the storm could bring “heavy snow and blowing snow that will cause dangerous conditions and will be a threat to life and property” in D.C. Read more…

When we think about birth control, we tend to think of women. But a German inventor wants to flip the switch on that discussion with his latest creation.

Introducing the “sperm switch,” named the Bimek SLV, which is the brainchild of Clemens Bimek. The device claims to allow men to block sperm from mixing with semen before ejaculation

It’s Bimek’s answer to male contraception and an alternative to a vasectomy.

During a vasectomy, the tubes that carry sperm are closed or blocked, and sperm can no longer enter the seminal fluid. Instead, the body absorbs the sperm. Read more…

It’s an age old question: Can cutting pizza ever be truly equal?

Many have wracked their brains trying to devise the perfect slice. Some cut in large triangles, which doesn’t always go as planned; others cut in small slivers; still others opt for the rather unpopular (and frankly, sadistic) square piece.

You just can’t please everyone. But mathematicians Joel Haddley and Stephen Worsley at University of Liverpool in England believe they have cracked the code for perfect equality at the dinner table by cutting somewhat complex, curved slices — also known as monohedral disc tiling. Read more…
