Biggest Scientific Breakthroughs Of 2014

This year, humanity landed on its first comet, a child was born to a woman with a transplanted womb, and a fossilized sea shell forced us to reconsider our conceptions of human culture. Those are just a taste of the 20 achievements, innovations, and advances we've selected for our roundup of 2014's biggest… » 12/19/14 12:40pm 12/19/14 12:40pm

Stem Cells Can Be Turned Into Killing Machines That Fight Brain Tumors

Researchers from Harvard Medical School have genetically engineered stem cells to produce and secrete toxins which kill brain tumors, without killing normal cells or themselves. Though the work was performed on mice, researchers call it "the future of cancer treatment." Clinical trials could start within five years. » 10/27/14 8:20am 10/27/14 8:20am

Did Scientists Just Develop A Viable Cure For Type 1 Diabetes?

In what's being called one of the most important advances to date in the field, researchers at Harvard have used stem cells to create insulin-producing beta cells in large quantities. Human transplantation trials could only be a few years away. » 10/10/14 1:00pm 10/10/14 1:00pm

A Movie About Science Fraud Is Killing At The Korean Box Office

A movie based on the scandal surrounding disgraced South Korean cloning expert Woo-Suk Hwang has been topping box office sales in the region since it debuted last week. » 10/09/14 3:30pm 10/09/14 3:30pm

Two genetic programs have been discovered that turn stem cells into blood. The method, which mirrors the way blood is produced in the body, allows researchers to make both white and red blood cells. Encouragingly, the researchers produced 30 million blood cells for every million stem cells. » 7/14/14 4:00pm 7/14/14 4:00pm

Cloned stem cells are better than re-programmed ones

Stem cells are versatile tools that can potentially be used to treat various disorders, or be directed to grow into much needed organs. The traditional way to obtain embryonic stem cells, the most versatile of them all, has been through fertilizing an egg with a sperm. Unfortunately, this causes some issues for… » 7/09/14 2:37pm 7/09/14 2:37pm

Inside a Corrupt Stem Cell Research Lab

The well-funded lab of stem cell researcher Piero Anversa has come under fire following the retraction of one of their papers on the regenerative properties of stem cells. Now, more of their research is under investigation. Over at Retraction Watch, one former lab worker speaks out about the atmosphere of "fear" and… » 6/02/14 9:10am 6/02/14 9:10am

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

More Evidence That Youthful Blood Can Reverse The Effects Of Aging

A few years ago, scientists from Stanford discovered that it's possible to reverse cognitive decline in old mice by injecting them with the blood of the young. Now, researchers have isolated the mechanism responsible for this rejuvenation — and it's a protein that's found in humans as well. » 5/05/14 12:25pm 5/05/14 12:25pm

Supercentenarian's Blood Provides Clues To Extending Human Life

Prior to her death at the tender age of 115, Hendrikje van Andel-Schipper was the world's oldest woman. Recently, scientists had the opportunity to study her blood — and what they discovered could have serious implications to the future of rejuvenation therapies. » 4/23/14 2:47pm 4/23/14 2:47pm

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

Soon We May Be Mass Producing Human Blood

Researchers in the UK have developed a technique to culture universal type-O blood from stem cells. It's the first time scientists have manufactured blood to the appropriate quality and safety standards for transfusion into a human being. It's a breakthrough that could eventually end blood shortages in emergencies. » 4/14/14 11:21am 4/14/14 11:21am

Co-author of stem-cell study 'loses faith' in paper

After claiming to have developed a novel technique for coaxing the growth of stem cells in an acid bath, Japanese researchers have come under scrutiny for apparent irregularities. In the latest twist, one of the paper's coauthors has admitted that the study should be retracted. » 3/11/14 12:20pm 3/11/14 12:20pm

A potential Nobel-winning stem-cell study is now under investigation for irregularities. Haruko Obokata rocked the science world last month by showing how stem-cells could be reprogrammed by an acid bath. Japan's RIKEN institute has now launched an inquiry following allegations of duplicate images and numerous failed… » 2/18/14 11:30am 2/18/14 11:30am

New research suggests women can make sperm, and men can make eggs

What started as an investigation into developmental mouse biology has become a lot more than that. Biologist Katsuhiko Hayashi discovered a way to turn mouse skin cells into sperm and egg cells — and actually used these modified cells to create a living baby mouse. The question is, can it work in humans? » 8/21/13 4:26pm 8/21/13 4:26pm

Your replacement retinas might look like this

For people going blind from retinal degeneration, there are almost no therapies. Their vision dims and they lose their sight as doctors look on helplessly. But a new experiment involving retinas grown from stem cells promises a new direction for research — and, in the future, a possible treatment. » 7/22/13 5:10pm 7/22/13 5:10pm

Toddler with bioengineered windpipe dies three months after surgery

Two year-old Hannah Warren passed away this past Saturday at the Children’s Hospital of Illinois. Born without a trachea, she was the youngest recipient of a bioengineered organ — one that was grown from her very own stem cells. She will be remembered as a pioneer in regenerative medicine. » 7/09/13 2:39pm 7/09/13 2:39pm

How to grow a human heart in three (relatively) easy steps

Could this be the secret to limb regrowth in humans?

Cut off part of an amphibian, and it'll regrow. But humans and other mammals can only regrew the very tips of our fingers and toes, if they're cut off. But the mechanism that makes that small feat happen could be the key to unlocking the secret of full limb regeneration in humans. » 6/13/13 4:30pm 6/13/13 4:30pm
