Are We Becoming More Stupid? Human Brain Has Been 'Shrinking For The Last 20,000 Years'

Old big head: A 3D image replica of a 28,000-year-old skull found in France shows it was 20 per cent larger than ours

From The Daily Mail:

It's not something we'd like to admit, but it seems the human race may actually be becoming increasingly dumb.

Man's brain has been gradually shrinking over the last 20,000 years, according to a new report.

This decrease in size follows two million years during which the human cranium steadily grew in size, and it's happened all over the world, to both sexes and every race.

From Popular Mechanics:

Evolutionary advance saw stone-age humans master the art of hand-toolmaking and paved the way for language to develop.

Stone-age humans mastered the art of elegant hand-toolmaking in an evolutionary advance that boosted their brain power and potentially paved the way for language, researchers say.

The design of stone tools changed dramatically in human pre-history, beginning more than two million years ago with sharp but primitive stone flakes, and culminating in exquisite, finely honed hand axes 500,000 years ago.

Europe Simulates Total Cyber War

From The BBC:

Essential web services have come under simulated attack as European nations test their cyber defences.

The first-ever cross-European simulation of an all out cyber attack was planned to test how well nations cope as the attacks slow connections.

The simulation steadily reduced access to critical services to gauge how nations react.

The exercise also tested how nations work together to avoid a complete shut-down of international links.

Google Limits Facebook Access to Gmail Contacts

From The Wall Street Journal:

Google Inc. is launching a salvo against Facebook Inc., saying it will no longer allow the social network to grab information about Google users' social and professional contacts in Gmail, Google's email service.

Google has always allowed Google users to transfer data, including their contacts, to other websites. Until now, new Facebook users could find out whether their contacts on Gmail also had Facebook accounts, simply by typing in their Gmail user name and password as part of the Facebook signup process.

Are Holograms The Next Step For 3D Tech?

Holograms, once seen only in science-fiction movies, are swiftly becoming a reality. Newscom

From Christian Science Monitor:

3D TV sets and 3D movies are everywhere in 2010. 3D holograms could be next.

Forget regular old 3D movies, which have crowded the marketplace with alarming alacrity in recent months. Forget even 3D TV. How about a 3D hologram – a three-dimensional telepresence, of the kind once seen only in the most speculative of science-fiction flicks? The technology might be even closer than you think.

The current issue of the science journal Nature features an extensive report from a group of Arizona researchers who succeeded in creating a real-time image – one that can be viewed without glasses – from multiple angles. (Just like in "Star Wars"!) The image, the researchers said, is recorded using a battery of cameras:

Atlantic Current Backward During Ice Age

The Gulf Stream brings warm surface water northwards from the tropics to high latitudes, where it cools, sinks and flows southwards at depth. Changes in this Atlantic 'meridional overturning circulation' (MOC) would have profound implications for climate. Credit: National Oceanography Centre

From Cosmos:

SYDNEY: The Atlantic Ocean current, which may be affected by future climate change, today takes heat north to Europe but 10,000 years ago it was weaker and flowed in the opposite direction.

"[The opposite flow in the Atlantic Ocean] explains the presence of huge ice sheets in Europe and North America during that cold climatic period," said César Negre, an environmental scientist at the Autonomous University of Barcelona in Spain, and co-author of the letter in the British journal Nature.

In First Test Of Interstellar GPS, Team Uses Distant Pulsars To Determine Position In Space

Pulsar Positioning It beats rolling down the window and asking for directions. NASA

From Popular Science:

Global Positioning Systems work famously here on the home planet because we control all of the moving parts; put some satellites in the sky, equip a device with the proper hardware to communicate with them, and you can locate yourself just about anywhere. But how would we locate ourselves in deep space? For that kind of spatial location, a team of Italian researchers have devised a way to calculate one’s position in space using pulsars as interstellar navigation beacons.

Cassini Camera Stops Shooting Snaps

From Wired Science:

NASA’s Cassini orbiter, the powerhouse producer of mind-blowing Saturn photos, unexpectedly put itself into “safe mode” at 7 p.m. EDT, Tuesday, Nov. 2. Engineers still don’t know why.

The craft automatically triggers its safe-mode settings whenever something happens that requires attention from mission controllers on the ground. Since going into safe mode, Cassini has stopped collecting science data and sent back only data on engineering and spacecraft health.

That’s normal, said Cassini program manager Bob Mitchell in a press release.

Spring Break-Ups: Graphic Of Facebook Updates Shows When People Are Most Likely To End A Relationship

The Facebook graphic shows most people break up at Spring Break or Christmas

From The Daily Mail:

If your relationship is rocky and it’s coming up to Christmas, beware: someone might be about to give you some bad news.

A designer who uses hard data to come up with interesting graphics and images has found which points in the year are the most popular for splitting up with partners.

David McCandless pulled information from 10,000 Facebook status updates which used the phrases ‘break up’ or ‘broken up’ and plotted them on a graph.

Gravity Suit Mimics Earth's Pull For Astronauts

Photo: The suit is made of a fabric with carefully tailored stretchiness

From The BBC:

A stretchy suit that mimics the effects of the Earth's gravity has been developed in the US to spare astronauts the ill effects of long missions of weightlessness.

Returning astronauts have lower bone density and muscle mass and can even suffer separation of their vertebrae.

The suit is made of a fabric with carefully tailored stretchiness.

It creates more of a pull at its wearer's feet than at the shoulders, replicating gravity's pull on Earth.

From Popular Science:

The new round of experiments aim to find out what matter looked like at the dawn of time.

Smashing protons at high energies is fun and all, but researchers at the Large Hadron Collider are taking a vacation from their day-to-day proton smashing, and taking a trip back to the very origins of the universe. Starting this month and continuing for four weeks, the LHC will accelerate and then collide lead ions – that is, entire atomic nuclei – to create a series of miniature Big Bangs that will let researchers take a look at the quark-gluon plasma that existed just a fraction of a second after the universe was born.

New York To Sydney In Just 2hrs 30mins: Nasa To Develop 'Hypersonic' Passenger Jets That Travel At Five Times The Speed Of Sound

From The Daily Mail:

NASA is planning to build hypersonic jets that will fly through the Earth’s atmosphere and slash flight times around the world to a few hours at most.

The US space agency wants to manufacture a craft that would travel at five times the speed of sound and bring in a new age of aircraft akin to a turbo-charged Concorde.

Travelling at such speed would reduce the flight time from New York to Sydney to around two-and-a-half hours, from the 21 hours it is now.
