Thanks to advances in 3-D printing, it’s now possible to whip up everything from pizza to prosthetics to human organs with the push of a button.
Now researchers have created a 3-D printer that works on the atomic scale, assembling complex molecules from scratch. And they say their molecule-making machine could revolutionize the drug-development process and simplify the fabrication of solar cells and other high-tech products.
A drug discovery revolution? “We’re really excited about the immediate impacts that this will have on drug discovery,” Dr. Martin D. Burke, a professor of chemistry at the University of Illinois at Urbana–Champaign and one of the researchers, says in a video released by the university.
Arctic sea ice this year is the smallest in winter since satellite records began in 1979, in a new sign of long-term climate change, U.S. data showed on Thursday.
The ice floating on the Arctic Ocean around the North Pole reached its maximum annual extent of just 14.54 million square kms (5.61 million sq miles) on Feb. 25 – slightly bigger than Canada – and is now expected to shrink with a spring thaw.
“This year’s maximum ice extent was the lowest in the satellite record, with below-average ice conditions everywhere except in the Labrador Sea and Davis Strait,” the U.S. National Snow and Ice Data Center (NSIDC) said in a statement.
Researchers examining a nearly 1,000-year-old statue of Buddha on display in Holland discovered something very unusual hidden inside: the mummy of a meditating monk.
Calling the mummy its “oldest patient ever,” the Meander Medical Center in the Dutch city of Amersfoort used a CT scanner to take images of the body inside the statue and an endoscope to examine the thoracic and abdominal cavities.
The mummy is believed to be that of Liuquan, a Buddhist monk who died in China around 1,100 A.D. During their examination, the researchers found that the mummy’s internal organs had apparently been removed and the space filled with “paper scraps that were printed with ancient Chinese characters,” the hospital said in a news release.

Scientists are going gaga over the recent discovery of a baby woolly rhino.
The pristine specimen of the tiny extinct rhino–the only one of its type ever found–was discovered in permafrost along the bank of a stream in Siberia’s Sakha Republic, The Siberian Times reported.
“At first we thought it was a reindeer’s carcass, but after it thawed and fell down we saw a horn on its upper jaw and realized it must be a rhino,” Alexander ‘Sasha’ Banderov, the hunter who made the discovery, told the Times. “The part of the carcass that stuck out of the ice was eaten by wild animals, but the rest of it was inside the permafrost and preserved well.”

Sea levels across the Northeast coast of the United States rose nearly 3.9 inches between 2009 and 2010, according to a new study from researchers at the University of Arizona and the National Oceanic and Atmospheric Administration. The waters near Portland, Maine, saw an even greater rise — 5 inches — over the two-year period.
While scientists have been observing higher sea levels across the globe in recent decades, the study found a much more extreme rise than previous averages. Such an event is “unprecedented” in the history of the tide gauge record, according to the researchers, and represents a 1-in-850 year event.
“Unlike storm surge, this event caused persistent and widespread coastal flooding even without apparent weather processes,” the study’s authors wrote. “In terms of beach erosion, the impact of the 2009-2010 [sea level rise] event is almost as significant as some hurricane events.”

Spacewalking astronauts routed more than 300 feet of cable outside the International Space Station on Saturday to prepare for the arrival of new American-made crew capsules. It was the first of three spacewalks planned for NASA astronauts Butch Wilmore and Terry Virts over the coming week.
Altogether, Wilmore and Virts have 764 feet (233 meters) of cable to run outside the space station. They got off to a strong start Saturday, rigging eight power and data lines, or about 340 feet (105 meters). The longest single stretch was 43 feet (13 meters). “Broadening my resume,” Virts observed.
NASA considers this the most complicated cable-routing job in the 16-year history of the space station. Equally difficult will be running cable on the inside of the complex.
Tiny amounts of lead, chemical flame retardants and organophosphate pesticides, among other toxins, course through the blood of nearly every American. But just how much worry is a little poison worth?
A lot, especially when considering the cumulative effects of this chemical cocktail on children, warns a video unveiled Thursday during an environmental health conference in Ottawa, Canada. The seven-minute project, “Little Things Matter,” draws on emerging scientific evidence that even mild exposures to common contaminants can derail normal brain development — lowering IQs and raising risks of behavioral conditions such as attention deficit hyperactivity disorder, or ADHD.
“The chemical industry argues that the effect of toxins on children is subtle and of little consequence,” co-producer Bruce Lanphear, an environmental health expert at Simon Fraser University in British Columbia, states in the video. “But that is misleading.”
Ever since I was little, I’m always fascinated with the images printed on the pages of travel magazines. Until today, those images still lingers in my memory. I started traveling to fulfill my dream, and that dream is to turn those images into reality, to experience how it feels like to be in a place where I have imagined myself to be. Now, I’m living the dream!
