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, [...]

This photograph shows a female of an as yet un-named boneworm in the genus Osedax, which has been carefully removed from the whale bone in which it was growing.
It sounds like a classic horror story — eyeless, mouthless worms lurk in the dark, settling onto dead animals and sending out green “roots” to devour their [...]

Artist’s impression of a baby star still surrounded by a protoplanetary disc in which planets are forming.
A ground-breaking census of 500 stars, 70 of which are known to host planets, has successfully linked the long-standing “lithium mystery” observed in the Sun to the presence of planetary systems. Using ESO’s successful HARPS spectrograph, a team of [...]

Mobile phones and other cordless telephones have a biological effect on the brain, according to new research.

A study at Örebro University in Sweden indicates that mobile phones and other cordless telephones have a biological effect on the brain. It is still too early to say if any health risks are involved, but medical researcher Fredrik [...]

Pacific ocean. Did water come from ice-covered asteroids that may have reached the Earth around one hundred million years after the birth of the planets?

Contrary to preconceived notions, the atmosphere and the oceans were perhaps not formed from vapors emitted during intense volcanism at the dawning of our planet. Francis Albarède of the Laboratoire des [...]

NASA scientists studying the origin of life have reproduced uracil, a key component of our hereditary material, in the laboratory. They discovered that an ice sample containing pyrimidine exposed to ultraviolet radiation under space-like conditions produces this essential ingredient of life.

Electron beam freeform fabrication process.
A group of engineers working on a novel manufacturing technique at NASA’s Langley Research Center in Hampton, Va., have come up with a new twist on the popular old saying about dreaming and doing: “If you can slice it, we can build it.”

The Human eye
Autism affects an estimated 1 in 150 children today, making it more common than childhood cancer, juvenile diabetes and pediatric AIDS combined. Despite its widespread effect, autism is not well understood and there are no objective medical tests to diagnose it. Recently, University of Missouri researchers have developed a pupil response test that [...]

Schematic diagram to show how the mechanical advantage and active muscle volume in the dinosaur hind limb were reconstructed.
Were dinosaurs “warm-blooded” like present-day mammals and birds, or “cold-blooded” like present day lizards? The implications of this simple-sounding question go beyond deciding whether or not you’d snuggle up to a dinosaur on a cold winter’s evening.

Swift X-ray observations of galaxy NGC 5408 indicate its ultraluminous X-ray source undergoes periodic changes every 115.5 days.

While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by. Now, astronomers at NASA’s Goddard Space Flight Center in Greenbelt, Md., find [...]

Text messaging on a mobile phone.

The world record for fastest text message typing is held by a 21-year old college student from Utah, but his dexterous digits could mean serious injury later on. Most adults aged 18-21 prefer texting over e-mail or phone calls, and ergonomics researchers are starting to wonder whether it’s putting the [...]

When a fetus is smaller than expected for the number of weeks of pregnancy, due to associated problems like a poorly developed heart, health concerns as severe as brain damage can result.

This male Hetaerina damselfly from the occisa species has red spots at the base and tip of its wings but no black pigmentation.
Why do so many animal species — including fish, birds and insects — display such rich diversity in coloration and other traits? In new research, Gregory Grether, UCLA professor of ecology and evolutionary [...]

A highly focused laser beam (at right) is used to apply mechanical force (shown as a double headed arrow) to a microsphere (white) coated with histocompatibility protein.

The immune system’s T cells have the unique responsibilities of being both jury and executioner. They examine other cells for signs of disease, including cancers or infections, and, if [...]

Unlike humans, zebrafish are able to regenerate amputated appendages.
The search for the holy grail of regenerative medicine — the ability to “grow back” a perfect body part when one is lost to injury or disease — has been under way for years, yet the steps involved in this seemingly magic process are still poorly understood.

the Mercury Surface

A NASA spacecraft gliding over the battered surface of Mercury for the second time this year has revealed more previously unseen real estate on the innermost planet. The probe also has produced several science firsts and is returning hundreds of new photos and measurements of the planet’s surface, atmosphere and magnetic field.

The first human embryonic stem cell treatment approved by the FDA for human testing has been shown to restore limb function in rats with neck spinal cord injuries — a finding that could expand the clinical trial to include people with cervical damage.

This image represents “copolymer micelles,” tiny drug-delivery spheres that could be used in a new approach for repairing damaged nerve fibers in spinal cord injuries. The bottom graphs show data indicating damaged spinal cord tissue recovered its “action potential,” or ability to transmit signals, after treatment with the micelles.
Researchers at Purdue University have discovered a [...]

NASA’s Spitzer Space Telescope captured this infrared image of a giant halo of very fine dust around the young star HR 8799.
Before our planets found their way to the stable orbits they circle in today, they wiggled and jostled about like unsettled children. Now, NASA’s Spitzer Space Telescope has found a young star with evidence [...]

The Mojave Desert. As the climate gets warmer, arid soils lose nitrogen as gas, reports a new Cornell study. That could lead to deserts with even less plant life than they sustain today, say the researchers.

Artist’s rendering of viruses. Scientists have developed synthetic molecules capable of enhancing the body’s immune response to HIV and HIV-infected cells, as well as to prostate cancer cells.
Researchers at Yale University have developed synthetic molecules capable of enhancing the body’s immune response to HIV and HIV-infected cells, as well as to prostate cancer cells. Their [...]

White-faced Capuchin (Cebus capucinus) checking its nails
Research at the universities of Liverpool and Oxford into the finger length of primate species has revealed that cooperative behavior is linked to exposure to hormone levels in the womb.

It was tiny music to the ears, but their cuteness was overwhelming
Each week the photos that come across our desk are both amazing, weird, mysterious, strange, and wonderful. And those are just the photos that people have take of me.  A great photo is an inspiring piece of culture. It has a way of capturing [...]

Artist’s rendering of a human fetus growing inside the womb.
From their very first days, newborns’ cries already bear the mark of the language their parents speak, reveals a new study published online on November 5th in Current Biology, a Cell Press publication. The findings suggest that infants begin picking up elements of what will be [...]

Hemigraphis alternata, or purple waffle plant, one of the highest ratedornamentals for removing indoor air pollutants.

Air quality in homes, offices, and other indoor spaces is becoming a major health concern, particularly in developed countries where people often spend more than 90% of their time indoors. Surprisingly, indoor air has been reported to be as much [...]
