Kids Who Own Dogs Are More Active
From Live Science:
When little Johnny or Molly asks for a puppy for their birthday, parents may want to give in. New research in England suggests children whose families own dogs are more active than those without a furry friend running around.
The research could have implications for childhood obesity in the United States, where 17 percent of 2- to 19-year-olds are obese, according to a 2007-2008 survey by the Centers for Disease Control and Prevention (CDC). Among 6- to 19-year-olds, obesity has tripled over the past two decades, according to the CDC.

From CNET:
Generating a news frenzy usually reserved for Apple product launches, pranksters turned Twitter into wormville this morning. The fast-spreading exploits proved two things: Twitter is undoubtedly now a mainstream service, and it's joined the ranks of big-time tech companies as a target for hackers.
Security experts interviewed by CNET say the messaging service has done a fair job of protecting itself so far, but will have to be more careful with its coding if it wants to be trusted for news aggregation, integration on corporate sites, and as a useful international communication tool.

From New Scientist:
Can the rate of past discoveries be used to predict future ones? We may soon find out. Two researchers have used the pace of past exoplanet finds to predict that the first habitable Earth-like planet could turn up in May 2011.
In 1965, Intel co-founder Gordon Moore observed that the number of transistors that fit on a chip doubles about once every two years – a trend now known as Moore's law. Samuel Arbesman of Harvard Medical School in Boston wants to see if scientometrics – the statistical study of science itself – can similarly be used to not only study past progress but also to make predictions.

U.S. Army Shows Renewed Interest In Zeppelins
In demand: The U.S. Army has ordered three new airships to be built and fitted with high-tech surveillance equipment so they can be used in Afghanistan
Are Zeppelins About To Take Off Again - Or Is It Just Hot Air? -- The Daily Mail
As we soar up into the grey skies above Lake Constance - propellers whirling, seat belts tightly fastened and everyone brandishing their cameras in excitement - something feels ever so slightly strange.
It could be the gentle breeze coming in through the wide open windows and the long ropes dangling in front of the cockpit in an alarmingly relaxed way.
Or perhaps it's the fact that the twin 200hp engines are so quiet I can hear my fellow passengers unwrapping toffees and whispering, and Hans-Paul the pilot clearing his throat and swallowing.

The Worst Part of GoingTo Space? Your Fingernails Come Off
Oh, It Hurts Some astronauts report losing their fingernails on spacewalks because of bulky gloves that cut off circulation and chafe against their hands. To avoid this inconvenience, a couple astronauts have taken to ripping off their own fingernails before reaching orbit. NASA
From Popular Science:
Did you think drinking your own urine was bad? To truly test whether you have the right stuff, imagine ripping out your own fingernails, on purpose.
A couple of astronauts have done this before going into orbit, because they figure it’s better than losing them inside chafing, unwieldy spacesuit gloves, according to Dava Newman, director of MIT’s technology and policy program and director of the university’s Man Vehicle Lab. Newman, who has studied space-related injuries, told a group of journalists at MIT that some astronauts have reported losing their fingernails during spacewalks. Fingernail trauma and other hand injuries are spacewalkers’ biggest complaint, she said.

British Scientists Invent 'Skylon' Spaceplane That Will Take Tourists Into Orbit At Five Times The Speed Of Sound
The 270ft-long Skylon space plane will be able to take passengers into space at a fraction of the current cost
From The Daily Mail:
A space aircraft that can take off from an ordinary airport runway before carrying tourists into orbit could be a reality with 10 years, according to British scientists.
The 270ft Skylon plane will cost about £700m to build and will be able to carry 24 passengers.
Built by British engineering firm Reaction Engines, the aircraft has no conventional external engines.
Instead the Skylon will travel at five times the speed of sound using two internal engines that suck hydrogen and oxygen from the atmosphere to send it 18 miles above the ground – and out of Earth’s atmosphere.

What's Eating The Stars Out Of Our Galaxy's Heart?
From The New Scientist:
The centre of the Milky Way is darker than you'd expect – and not just because it's home to a supermassive black hole
A LITTLE over 25,000 light years away lies the most mysterious place in the nearby universe. Jam-packed with colliding stars and cloaked in dust, it is the centre of our galaxy. At its very heart, we suspect, lurks a monstrous black hole more than 4 million times as massive as the sun. Known as Sagittarius A*, it is thought to rip stars apart, orchestrating stellar mayhem as it warps the very fabric of space and time.

SETI 2060, Do We Make Contact By Then?
From Discovery News:
This month the National Radio Astronomy Observatory’s Green Bank Science Center is celebrating the 50th anniversary of the modern day search for extraterrestrial intelligence (SETI).
In 1960 a young radio astronomer, Frank Drake, undertook a bold and visionary experiment: He used the 85-foot dish antenna at Green Bank, W.V. to listen for radio signals from extraterrestrial civilizations.
Drake recently retired from the SETI Institute in Palo Alto, Calif., without finding his aliens. He’s not alone. As early as the turn of the last century Nicola Tesla and the father of radio, Guglielmo Marconi, were independently listening for signals from Martians.

The Ultimate Field Guide to Subatomic Particles
From io9:
Muons, neutrinos, supersymmetric partners, the infamous Higgs boson - with so many different subatomic particles flying about, it's no wonder theoretical physics can be so confusing. That's why we made this (reasonably) simple guide to all the different elementary particles.
This is, as you might imagine, a pretty big topic, so we're splitting it into (at least) two posts. Today we're going to deal with just the particles that physicists are certain (or, at least, reasonably certain) exist, and then tomorrow we'll get into the even stranger world of particles that have been hypothesized but may or may not actually exist. I've also made a handy cheat sheet listing all the elementary particles and their vital statistics, which you can find here. But to understand what all of that means, you'll really want to read on.

The New Twitter Isn't Nearly New Enough
From Daily Finance:
As a Twitter user, I was interested in seeing just how different Twitter.com's new incarnation actually is, especially because it's been billed as the most significant product release for the micro-messaging service in a long time.
Would it finally give me a reason to ditch my Twitter client and go back to Twitter.com? Would it finally produce a revenue model commensurate with the company's stiff venture capital valuation and immense promise? Would it leap tall buildings in a single bound? Alas, none of the above. The new Twitter is fairly tame -- and fairly indicative of the troubles that have beset the popular but not easily monetizable company.

US Assessment Of Terrorist Threats Poor, Says Panel
From New Scientist:
Only "low confidence" should be placed in most of the risk analyses of terrorist threats conducted by the US Department of Homeland Security, concludes a review by a National Research Council panel.
Created after the 9/11 attacks to cover national perils ranging from terrorism to natural disasters, the DHS got off to a rough start. Critics blasted its lack of attention to natural disasters after its bungled response to hurricane Katrina.
Yet the panel finds that DHS models for natural disaster risks are "near the state of the art" and well suited to assess the effects of earthquakes, floods and hurricanes.

How Mass Migration Might Have Evolved
From Wired Science:
Just a few small changes in the social behaviors of even solitary animals may set in motion an evolutionary cascade ending in massive, globe-spanning migrations, suggests a study of migration’s origins.
Such migrations — caribou across the Arctic and wildebeest across the Serengeti, birds and butterflies over oceans — are among nature’s most beautiful and mystifying phenomena. Many models suggest how migration works now, in terms of individual actions producing collective behavior; but how it could have started in the first place is far harder to explain.
