A suite of five ancient crocs, including one with teeth like boar tusks and another with a snout like a duck’s bill, have been discovered in the Sahara by National Geographic Explorer-in-Residence Paul Sereno. The five fossil [...]

Volcano eruption on Reunion Island in the Indian Ocean.
Much of our planet’s mineral wealth was deposited billions of years ago when Earth’s chemical cycles were different from today’s. Using geochemical clues from rocks nearly 3 billion years old, a group of scientists including Andrey Bekker and Doug Rumble from the Carnegie Institution have made the [...]

An ear of corn on the stalk in a field ready for harvesting.
A four-year, multi-institutional effort co-led by three Cold Spring Harbor Laboratory (CSHL) scientists culminated today in publication of a landmark series of papers in the journal Science revealing in unprecedented detail the DNA sequence of maize (Zea mays). Maize, or corn, as it [...]

This tiny worm became temporarily paralyzed when scientists fed it a light-sensitive material, or “photoswitch,” and then exposed it to ultraviolet light.
In an advance with overtones of Star Trek phasers and other sci-fi ray guns, scientists in Canada are reporting development of an internal on-off “switch” that paralyzes animals when exposed to a beam of [...]

Scientists from the UCLA Department of Neurology have confirmed that blindness causes structural changes in the brain, indicating that the brain may reorganize itself functionally in order to adapt to a loss in sensory input.
Visually impaired people appear to be fearless, navigating busy sidewalks and crosswalks, safely finding their way using nothing more than a [...]

A reconstructed image of the giant extinct moa.
The evolutionary history of New Zealand’s many extinct flightless moa has been re-written in the first comprehensive study of more than 260 sub-fossil specimens to combine all known genetic, anatomical, geological and ecological information about the unique bird lineage.

Postdoctoral student Greg Welch removing a sample from the microwave reactor.

Professor Guillermo Bazan and a team of postgraduate researchers at UC Santa Barbara’s Center for Polymers and Organic Solids (CPOS)  have announced a major advance in the synthesis of organic polymers for plastic solar cells.

Depression is as much of a risk factor for mortality as smoking, new research has found.
A study by researchers at the University of Bergen, Norway, and the Institute of Psychiatry (IoP) at King’s College London has found that depression is as much of a risk factor for mortality as smoking.

This image shows the mummy of Esankh, male, Third Intermediate Period (1070-712 BCE), undergoing CT scanning.
Hardening of the arteries has been detected in Egyptian mummies, some as old as 3,500 years, suggesting that the factors causing heart attack and stroke are not only modern ones; they afflicted ancient people, too.

Titanium dioxide (TiO2) nanoparticles, found in everything from cosmetics to sunscreen to paint to vitamins, caused systemic genetic damage in mice.
Titanium dioxide (TiO2) nanoparticles, found in everything from cosmetics to sunscreen to paint to vitamins, caused systemic genetic damage in mice, according to a comprehensive study conducted by researchers at UCLA’s Jonsson Comprehensive Cancer Center.

Artist’s conception of the “boiling disk” surrounding the massive young stellar object known as Orion Source I. A disk of hot, ionized gas surrounds the central star, blocking our view
The constellation of Orion is a hotbed of massive star formation, most prominently in the Great Nebula that sits in Orion’s sword. The glowing gas of [...]

An adult male extends his right arm toward an adult female in order to greet her.
Most of the linguistic functions in humans are controlled by the left cerebral hemisphere. A study of captive chimpanzees at the Yerkes National Primate Research Center (Atlanta, Georgia), reported in the January 2010 issue of Elsevier’s Cortex, suggests that this [...]

Over 5000 worked flints came from one small area, including flint cores used for tool creation, blades, flakes and ‘debitage’

Staff at the University of Leicester Archaeological Services (ULAS) have been excited by the results from a recently excavated major Prehistoric site at Asfordby, near Melton Mowbray, Leicestershire. The Mesolithic site may date from as early [...]

A genetic variation may contribute to how empathetic a human is, and how that person reacts to stress.
Researchers have discovered a genetic variation that may contribute to how empathetic a human is, and how that person reacts to stress. In the first study of its kind, a variation in the hormone/neurotransmitter oxytocin’s receptor was linked [...]

Normal synaptic activity in nerve cells protects the brain from the misfolded proteins associated with Huntington’s disease, researchers have discovered.
Investigators at Burnham Institute for Medical Research (Burnham), the University of British Columbia’s Centre for Molecular Medicine and Therapeutics and the University of California, San Diego have found that normal synaptic activity in nerve cells (the [...]

Adelie penguins have survived in Antarctica for thousands of years and are invaluable for genetic research.
Penguins that died 44,000 years ago in Antarctica have provided extraordinary frozen DNA samples that challenge the accuracy of traditional genetic aging measurements, and suggest those approaches have been routinely underestimating the age of many specimens by 200 to 600 [...]

Cynomolgus macaque. New research in these primates suggests that a gene delivery strategy that produces follistatin can improve muscle mass and function.
A study appearing in Science Translational Medicine puts scientists one step closer to clinical trials to test a gene delivery strategy to improve muscle mass and function in patients with certain degenerative muscle disorders.

The IMaX instrument not only depicts the solar surface, it also makes magnetic fields visible; these appear as black or white structures in the polarised light.
The Sun is a bubbling mass. Packages of gas rise and sink, lending the sun its grainy surface structure, its granulation. Dark spots appear and disappear, clouds of matter dart [...]

Captured on film

Obsessed with cameras much?  While you can probably deny it, the owner of this vehicle – the Camera Van – can’t.  Literally decked in thousands of cameras, it’s what the Google Street View cars would have looked like if their designers had some panache.  Or were clinically insane.  Either will do.
First created by [...]

“Whoa dude! Clean your lens or something”
The photos we have this week are guaranteed to hit you from left field. In fact, that’s where we keep all the things we want to hit you with – left field. If you are ever interested in going to left field, just turn around, you’ll find it on your blind [...]

It took over 11 hours to create these two “Where the Wild Things Are” chalk murals at Arnold DC, a Washington ad agency. Watch the timelapse video of their creation, using over 1,500 stills. Really cool.

Cassini-Huygens swings by Earth and accelerates towards Saturn.

When Europe’s comet chaser Rosetta swings by Earth on Nov. 13 for a critical gravity assist, tracking data will be collected to precisely measure the satellite’s change in orbital energy. The results could help unravel a cosmic mystery that has stumped scientists for two decades.

Yellow jewelweed (impatiens pallida) appears to have the ability to recognize ‘relatives’ from ’strangers’ and then shift resources for growth to benefit relatives.
Although plants have the ability to sense and respond to other plants, their ability to recognize kin and act altruistically has been the subject of few studies. The authors explored kin recognition in [...]

Sloan Digital Sky Survey spectroscopy of this inconspicuous blue object.
Astrophysicists at the University of Warwick and Kiel University have discovered two earth sized bodies with oxygen rich atmospheres — however there is a bit of a disappointing snag for anyone looking for a potential home for alien life, or even a future home for ourselves, [...]
