Researchers discover a virus that makes the toxin from black widow spider venom

Researchers discover a virus that makes the toxin from black widow spider venom Biotechnologists have discovered some horrifying new consequences of lateral gene transfer: a virus that started making the toxin from black widow spider venom, all by itself.It’s even less comforting that the virus acquired the ability to make the black widow toxin all on its own.

Brain implant used to restore paralyzed man’s sense of touch

Brain implant used to restore paralyzed man’s sense of touch In a new study, doctors have used a brain implant to return the sense of touch to a paralyzed man.By placing electrodes inside Copeland’s brain, doctors have basically created a new path for the electrical impulses associated with the sense of touch.

Deep-dwelling bacteria could rewrite our understanding of where alien life could take hold

Deep-dwelling bacteria could rewrite our understanding of where alien life could take hold Finding bacteria in extreme environments, like at thermal ocean vents or in the sulfur pools at Yellowstone, isn’t all that novel.In 1991, remote-control robots brought out samples of pitch-black fungi that had been growing inside the ruins of the Chernobyl reactor.

Scientists create new fluorescent protein to monitor the cell cycle

Scientists create new fluorescent protein to monitor the cell cycle When you need new cells, they can be created through a process called mitosis, whereby a cell makes a copy of itself.A new technique from Stanford (PDF) allows the cell cycle to be observed with more precision than ever before.

Scientists figure out how to tweak plant genomes to boost photosynthesis

Scientists figure out how to tweak plant genomes to boost photosynthesis Ample sunlight is good…except when there’s too much of it, which can cause damage to the plant’s cells.As the sun moves across the sky, changes in light can leave many leaves in the shade with a depressed rate of photosynthesis.

Researchers create a tiny tractor beam that totes bacteria around

Researchers create a tiny tractor beam that totes bacteria around “The principle underlying this laser beam is similar to the concept to be found in the television series Star Trek,” says Dr.In their new method, the Bielefeld researchers use a second laser beam as a single-cell optical trap — in other words, a tiny tractor beam — so that the cells float under the microscope and can be moved at will.

Scientists find another reason to cut your sugar intake: Alzheimer's disease

Scientists find another reason to cut your sugar intake: Alzheimer's disease researchers say they've spotted the molecular "tipping point" that could explain sugar's ties to Alzheimer's disease.Their findings provide further evidence that there might be a link between high blood sugar levels and the memory-robbing disease, though they don't prove that sugar causes Alzheimer's outright.

Here's another way to bury your pet — grow it into a tree

Here's another way to bury your pet — grow it into a tree Grow your loved one's remains into a remembrance tree thanks to the 'Living Urn'.The system works by placing your loved ones remains into the bio urn, adding a special root protection formula, as well as a growth mix.

Newly discovered rock formations could be fossils from earliest living organisms

Newly discovered rock formations could be fossils from earliest living organisms 5 billion years ago, and a new discovery in Canada indicates life developed not long after.28 billion years ago.

Researchers increase the storage capacity of DNA to 214 petabytes per gram

Researchers increase the storage capacity of DNA to 214 petabytes per gram Now a pair of researchers from Columbia University and the New York Genome Center have developed a process for storing 214 petabytes of data per gram of DNA.It’s data storage just like what we do with hard drives, but with much higher potential density.

The mystery of why pandas are black and white has been solved

The mystery of why pandas are black and white has been solved We finally know why pandas are black and white.They're a study in contrasts, with black fur that matches dark forests and white fur for snow-filled landscapes.

Meet the fluorescent tree frogs of South America

Meet the fluorescent tree frogs of South America Scientists in Argentina and Brazil say they've found the first solid evidence of a fluorescent amphibian, courtesy of the South American tree frog.Their findings, published Monday in the Proceedings of the National Academy of Sciences, offer clues into how this tiny tree frog survives in its environment.

Snail foreplay finally gets the dedicated research it has long deserved

Snail foreplay finally gets the dedicated research it has long deserved Foreplay that can last several hours and is mostly smell-stuff, stabbing with love darts and genitals that are similar to a rubber glove?So wild that it can fill a four-minute video where truly, every second brings new and previously unimaginable information thanks to PBS's digital studio series, Deep Look.

Hacked-together Lego Mindstorms bot kit brings science to a classroom near you

Hacked-together Lego Mindstorms bot kit brings science to a classroom near you Stanford researchers have hacked the Lego Mindstorms platform as a springboard to create a liquid-handling robotics kit, using inexpensive, off-the-shelf parts.” To fill that vacuum, the team created their own desktop liquid-handling robots that approach the performance of the far more costly automation systems found at universities and biotech labs, Riedel-Kruse said.
