Hacking Our Cells to Produce Solar Power Could Make Humans Heal Faster

Kinda like Wolverine.<p>Much like a gas-powered car, the human body relies on carbon-based fuels for energy. But for automobile engines and our cellular engines alike, burning carbon has intrinsic inefficiencies.<p>If we could upgrade our cells to run on solar power, the age-old restrictions of using …

'Designer babies' debate should start, scientists say

<b>Rapid progress in genetics is making "designer babies" more likely and society needs to be prepared, leading scientists have told the BBC.</b><p>Dr Tony Perry, a pioneer in cloning, has announced precise DNA editing at the moment of conception in mice.<p>He said huge advances in the past two years meant …

Study: Genes could retain 'memory' when passed to offspring

Research carried out by the University of Cambridge has revealed a way in which a parent's experiences can be passed on to their offspring's …

Arsenic Antidote Hidden In Our Genes

For centuries, arsenic was the go-to poison for murder.<p>If you wanted to knock off an heir to the throne or speed up the arrival of your inheritance, all you had to do was add a dollop of rat poison to your rival's food. They wouldn't see or taste it. And the police wouldn't detect it — at least not …

Heart muscle cells regrown in medical research breakthrough

Unlike animals such as the salamander and the zebrafish, humans are unable to easily regenerate heart cells, making it difficult to recover from the permanent damage caused by heart attacks.<p>But scientists from the Weizmann Institute of Science in Israel and the Victor Chang Institute in Sydney have …

Cloning Cows From Steaks (and Other Ways of Building Better Cattle)

Can animal geneticists breed—or clone—a cow that will taste great and have a smaller environmental hoofprint too?<p>The clones were so glad to see us, out on the frozen pasture, that they almost wouldn't let us out of the pickup. I had to shove one aside with the door to get out. Kelly Jones had …

Scientists Call For Moratorium On Human Genetic Experiments

Citing safety fears for babies, genetics researchers on Thursday called for a halt to experiments that would alter the DNA of human sperm, eggs, and embryos.<p>The moratorium plea, published in the journal <i>Nature</i>, suggests that genetic modification of babies is right around the corner, and may lead to …

Researchers have been programming peoples' immune systems to recognize and destory cancer.<p>Part of what makes cancers so insidious is that they’re not invaders: They’re our own cells turned against us. That means the body usually doesn’t see them as a threat. But over the last few years, teams at …

A Mind-Controlled Robotic Hand With A Sense Of Touch

Getting closer to lifelike<p>Denis Aabo Sørensen lost his left hand nine years ago, while handling fireworks. Since then, he has used prosthetic hands, but never one like this. Last year, a team of European engineers created for him a prosthetic hand that connects directly to the remaining nerves in …

Quantum Microscope May Be Able to See Inside Living Cells

By combining quantum mechanical quirks of light with a technique called photonic force microscopy, scientists can now probe detailed structures …

The Neuroscientist Who Wants To Upload Humanity To A Computer

Randal Koene is recruiting top neuroscientists to help him make humans live forever<p>Everything felt possible at Transhuman Visions 2014, a conference in February billed as a forum for visionaries to "describe our fast-approaching, brilliant, and bizarre future." Inside an old waterfront military …
