Paralyzed Man Walks Again After Brain Cells Are Injected into His Spine

Back in 2010, Darek Fidyka became paralyzed from the waist down after suffering stab wounds to his back. Now, after 19 months of treatment in which cells from his brain were transplanted into his spinal column, he can walk with a frame. Researchers are calling it a "historic breakthrough." » 10/21/14 2:30pm Yesterday 2:30pm

New "Programmable" Antibiotic Targets Drug-Resistant Genes

A fundamental drawback to antibiotics is that they indiscriminately target all of the bacteria in your body, including the good ones. So how cool would it be if we could engineer a smart antibiotic that targets specific strains of bacteria? Researchers at Rockefeller University have just taken us one major step… » 10/06/14 2:40pm 10/06/14 2:40pm

Breakthrough: Synthetic Meat Made From Stem Cells

Last year, scientists created the world's first lab-grown burger — and by all accounts it didn't taste half bad. Sadly, the cost of a single patty ran upwards of $385,000. Now, European researchers have developed a small-scale manufacturing technique for synthetic meat that could eventually prove revolutionary. » 5/20/14 9:30am 5/20/14 9:30am

"Surprising" Breakthrough in Multiple Sclerosis Mouse Study

In a recent experiment, mice with MS-like symptoms were able to walk and run again just two weeks after being injected with human neural stem cells. Even the researchers were unprepared for these incredible results. Though we're still far from a cure, it's a remarkable finding that hints at similar therapies for… » 5/15/14 9:00am 5/15/14 9:00am

The First Lifeform Capable Of Passing Down A Juiced-Up Version Of DNA

Scientists have engineered the first living microbe that can carry and pass down an expanded genetic code to future generations — one that has six base pairs instead of the usual four. It's a breakthrough that will not only allow us to build powerful new forms of life, it's also changing what we know about evolution. » 5/08/14 8:00am 5/08/14 8:00am

Researchers Clone Stem Cells From Human Adults

Scientists from South Korea have devised a technique for cloning adult stem cells that doesn't involve the destruction of human embryos. The resulting stem cells, which are highly personalized, could be used to treat illnesses such as heart disease and blindness — but the technique could also be used to clone adults. » 4/18/14 6:00pm 4/18/14 6:00pm
