Humans On Verge Of Causing 6th Great Mass Extinction -- Live Science

Are humans causing a mass extinction on the magnitude of the one that killed the dinosaurs?

The answer is yes, according to a new analysis — but we still have some time to stop it.

Mass extinctions include events in which 75 percent of the species on Earth disappear within a geologically short time period, usually on the order of a few hundred thousand to a couple million years. It's happened only five times before in the past 540 million years of multicellular life on Earth. (The last great extinction occurred 65 million years ago, when the dinosaurs were wiped out.) At current rates of extinction, the study found, Earth will enter its sixth mass extinction within the next 300 to 2,000 years.

NASA Refutes Alien Discovery Claim

From Discovery News:

On Saturday, aliens invaded.

On Monday, NASA denied their existence.

This might sound like the perfect X-Files storyline for conspiracy theorists to chew over (and they probably will, for months), but as you may have already guessed, something wasn't quite "right" about Richard Hoover's announcement of an extraterrestrial discovery inside samples of meteorites.

My Comment: If true .... it would have been an interesting story.

Two Suns Setting?

Two Suns Setting? Scientists Offer Explanations of Chinese Video -- ABC News

Pictures of Double Sun Go Viral in Web; Astronomers Suspect Optical Illusion or Hoax.

Early in the original "Star Wars" movie, there is a scene in which the restless young Luke Skywalker looks out at the two suns setting on his home planet of Tatooine.

It was a charming, exotic touch, and it was done simply. Two images of the earth's sun were superimposed next to each other.

Now, video of what looks like two suns setting has been broadcast by Chinese television -- and it's quickly spread all over the Web.

Pursuit Of The Universe's First Galaxy

In Pursuit Of The Universe's First Galaxy -- CBS News

If all goes according to plan, the James Webb space telescope will take to the stars in 2014. And scientists are counting down the days. The Webb is expected to offer them unprecedented views of the cosmos. The heir to the Hubble space telescope, the upcoming telescope has been taxed with a big job during its planned five-year space mission: no less than the job of photographing some of the universe's first-ever galaxies. With a 21-foot mirror, the Webb telescope will be powerful enough to take aim at the oldest stars and galaxies in the universe.

My Comment: I suspect that the discoveries that it will find will rewrite the book on the origins of the universe.

A Suicide Warning System On Facebook

Looking At Mars Impact Craters

This elongated depression is about 78 km in length, opens from just under 10 km wide at one end to 25 km wide at the other, and reaches a depth of 2 km. It is located at about 21°S / 55°E, and was probably caused by the impact of a train of projectiles. The data were acquired during orbit 8433 on 4 August 2010 using the High Resolution Stereo Camera on Mars Express. (Credit: ESA/DLR/FU Berlin (G. Neukum))

The Scars Of Impacts On Mars -- Science Daily

ScienceDaily (Mar. 7, 2011) — ESA's Mars Express has returned new images of an elongated impact crater in the southern hemisphere of Mars. Located just south of the Huygens basin, it could have been carved out by a train of projectiles striking the planet at a shallow angle.

The large Huygens basin (not visible in the main image but seen in the wider contextual image) is about 450 km in diameter and lies in the heavily cratered southern highlands. In this area there are many impact scars but none perhaps are more intriguing than the 'elongated craters'.

My Comment: That is one hell of an impact.

Has NASA Discovered Evidence Of Alien Life?

NASA Scientist Finds Evidence Of Alien Life -- Yahoo News/Digital Trends

Aliens exist, and we have proof.

That astonishingly awesome claim comes from Dr. Richard B. Hoover, an astrobiologist at NASA’s Marshall Space Flight Center, who says he has found conclusive evidence of alien life — fossils of bacteria found in an extremely rare class of meteorite called CI1 carbonaceous chondrites. (There are only nine such meteorites on planet Earth.) Hoover’s findings were published late Friday night in the Journal of Cosmology, a peer-reviewed scientific journal.

India: The Story Of An Emerging Scientific Superpower -- New Scientist

Why are Indians such a bunch of geeks? In Geek Nation, Angela Saini goes in search of the truth behind the stereotype.

At first, the truth seems hard to find. Dispiritingly, the first few chapters are filled not with the playful, passionate geeks Saini seeks, but with obsessive, socially inept nerds. Yes, they're different beasts.

From Popular Science:

If you could put all the data in the world onto CDs and stack them up, the pile would stretch from the Earth to beyond the moon, according to a new study. The world’s technological infrastructure has a staggering capacity to store and process information, reaching 295 exabytes in 2007, a reflection of the world’s almost complete transition into the digital realm. That's a number with 20 zeroes behind it, in case you're wondering.

From CBS News:

In a race against the clock, Mother Nature won. A Russian team that has been toiling around the clock to pierce through to a sub-glacial lake in Antarctica is calling it quits - for now - because of harsh winter weather that's freezing their hydraulic tools.

The sub-glacial Lake Vostok is located at the bottom of a 12,000 foot-thick ice sheet in Antarctica but the project leaders reported the evacuation of its team 29.53 meters short of the final destination. They plan to resume their work next spring, when temperatures allow them to again use their drills. Lake Vostok has some of the lowest recorded temperatures found anywhere, with the thermometer going as low as -129 degrees Fahrenheit.

Solar Physicists Will Soon have Their First 360-Degree View Of Our Star

Image: The Stereo satellites are already feeding data into space weather forecasts

Stereo Satellites Move either Side Of Sun -- BBC

Two US spacecraft have moved either side of the Sun to establish observing positions that should return remarkable new information about our star.

Launched in 2006, the Stereo satellites have gradually been drifting apart - one in front of the Earth in its orbit, the other lagging behind.

On Sunday, Nasa said the spacecraft had arrived at points that put the Sun directly between them.

It will give solar physicists the first 360-degree view of our star.

My Comment: The data from this satellite alignment is probably going to be astounding.

Say Hello To The Bloodhound Supercar

Construction Begins On Bloodhound Supercar -- BBC

Construction work formally begins this week on what is expected to be the world's fastest car.

Called Bloodhound, the vehicle has been designed to reach 1,000mph (1,600km/h).

The British car will attempt to set the mark as it breaks the land speed record on a dried out lake bed in South Africa's Northern Cape late next year.

Bloodhound has been in design for the past three years. It will be powered by a Eurofighter-Typhoon jet engine bolted above a hybrid rocket.
