From Discovery Magazine:

Save the date: Less than 3.7 billion years from now, the world is going to end, according to a new study.

A new study suggests the universe and everything in it could end within the Earth's lifespan -- less than 3.7 billion years from now -- and we won't know it when it happens.

But one expert says the result isn't valid because the researchers chose an arbitrary end point.

The universe began in a Big Bang about 13.7 billion years ago and has been expanding at an ever accelerating rate ever since.

Asteroid Lutetia Has Thick Blanket Of Debris

Photo: About 100km wide, Lutetia is the biggest asteroid yet visited by a spacecraft

From The BBC:

Lutetia, the giant asteroid visited by Europe's Rosetta probe in July, is covered in a thick blanket of dusty debris at least 600m (2,000ft) deep.

Aeons of impacts have pulverised the space rock to produce a shattered surface that in terms of texture is much like Earth's Moon, scientists say.

The finding is one of the first to emerge from the wealth of data gathered by Rosetta during its close flyby.

The details are being discussed this week at a conference in Pasadena, US.

From Technology Review:

The devices may one day help patients skip invasive and painful biopsies.

Technologies that analyze cancer cells that circulate through a patient's bloodstream could provide a less invasive way of monitoring cancer and selecting the best treatments. So Mehmet Toner and collaborators at Massachusetts General Hospital have developed a microfluidics chip that effectively captures these rare cells, which make up just one in a billion cells in blood, in high enough numbers to analyze them for molecular markers. The device also isolated clusters of tumor cells for the first time, which may help shed light on cancer's ability to spread, or metastasize, from its initial birthplace.

Signal Achievements In Army History (Photos)

In 1860, the man in the center of this photo, Albert Myer, became the first-ever signal officer of the U.S. Army. (He's seen here some months later during the Peninsula campaign of the Civil War.) While the government liked Myer's ideas on signaling well enough to establish the U.S. Army Signal Corps at that time, the early years of the undertaking faced any number of challenges--ungainly technology, bureaucratic infighting, lack of funding and staffing. But the seed was planted in those early days, and the Signal Corps has now been around for 150 years (making this year the sesquicentennial), at the forefront of technologies from the telegraph to radio, radar, and satellite communications.

From CNET:

A slew of upcoming iPad competitors won't be able to match Apple's tablet anytime soon, Deutsche Bank analyst Chris Whitmore said in a recent note to investors.

"We believe Apple's lead in the tablet market will prove difficult to close by the onslaught of competing products coming over the next several quarters," Whitmore said Monday in a research note obtained by Fortune. "Ultimately, we expect the slew of upcoming competition to fall flat from a user-experience standpoint while struggling to materially undercut the iPad on price."

Marine Life Census Charts Vast Undersea World

This new copepod, Ceratonotus steiningeri, was first discovered 5,400 metres deep in the Angola Basin in 2006. It was also collected in the southeastern Atlantic, as well as some 13,000 kilometres away in the central Pacific Ocean. Scientists are puzzled about how it achieved such widespread distribution and avoided detection for so long. Credit: Jan Michels

From Cosmos:

LONDON: Results of the first ever global marine life census have been unveiled, revealing a startling overview after a decade-long trawl through the murky depths.

The Census of Marine Life estimated there are more than one million species in the oceans, with at least three-quarters of them yet to be discovered.

The US $650-million international study discovered more than 6,000 potentially new species, and found some species considered rare were actually common.

What Makes Us Age? Ticking of Cellular Clock Promotes Seismic Changes in Chromatin Landscape Associated With Aging

Each time a cell divides, the protective "caps" at the tip of chromosomes (red and green dots) erode a little bit further. As telomeres wear down, their DNA undergoes massive changes in the way it is packaged. These changes likely trigger what we call "aging."

From Science Daily:

ScienceDaily (Oct. 4, 2010) — Like cats, human cells have a finite number of lives: once they divide a certain number of times (thankfully, more than nine) they change shape, slow their pace, and eventually stop dividing -- a phenomenon called "cellular senescence."

Strong Magnets With Printed Poles Have Endless Engineering Applications

From Popular Mechanics:

The Brilliant Idea: Magnets printed with multiple poles, opening the door to myriad applications.

Larry Fullerton set out to invent a self-assembling magnetic toy that would fuel his grandchildren’s passion for science. Instead, he invented a way to manipulate magnetic fields that redefines one of the fundamental forces of nature.

Fullerton’s breakthrough tramples the long-held assumption that magnets have two opposing poles, one on each side. He found that if he used heat to erase a magnetic field, he could then reprogram material to have multiple north and south poles of differing strengths. “People look at magnets as having a north pole and a south pole. That limits your thinking,” he says. “I came along from the field of radar and said, ‘Hey, that’s not a magnet—it’s a vector field!’”

Micro-Engraved Lenses Give Perfect Vision To Both Near- And Far-Sighted Eyes

Bifocals (Old.) Frank C. Müller

From Popular Science:

Near-sighted? Far-sighted? Middle-sighted? It doesn't matter--this "scratched" lens has you covered.

An inability to see both near and faraway objects isn't uncommon, but the classic solution--bifocals--is hardly cutting-edge. I mean, thanks, Ben Franklin, but how about something more modern? A new type of engraved lens, invented by an Israeli researcher, allows the eye to see perfectly whether the object is nearby or in the distance, without adjusting perspective. No matter your vision, these lenses claim to provide perfect clarity.

Wind Farms Can Affect Local Weather Patterns

One of the solutions would be changing the rotor design

From The BBC:

Wind farms, especially big ones, generate turbulence that can significantly alter air temperatures near the ground, say researchers.

As turbines often stand on agricultural land, these changes could in turn affect crop productivity.

In the journal Proceedings of the National Academy of Sciences (PNAS), the team says the impact could be reduced by changing rotor design.

Another option would be to site farms in areas with high natural turbulence.
