Mouse egg cells made entirely in the lab give rise to healthy offspring

Mouse egg cells made entirely in the lab give rise to healthy offspring

In work that raises the prospect of new infertility treatments and designer babies, researchers have used stem cells to grow fertile mouse egg cells for the first time entirely in a lab dish. The eggs gave rise to pups after being fertilized and implanted into rodent foster mothers. The method—which sometimes produced defective eggs and […]

A better hologram for fraud protection and wearable optics

A better hologram for fraud protection and wearable optics

Holograms are a ubiquitous part of our lives. They are in our wallets — protecting credit cards, cash and driver’s licenses from fraud — in grocery store scanners and biomedical devices. Even though holographic technology has been around for decades, researchers still struggle to make compact holograms more efficient, complex and secure. Researchers at the […]

Scientists Made Transparent Wood That’s Stronger Than Glass

Scientists Made Transparent Wood That’s Stronger Than Glass

Researchers at the University of Maryland were able pull away color and chemicals from a block of wood to leave it impressively see-through. The result is a material that is both stronger and more insulating than glass, with better biodegradability than plastic. “We were very surprised by how transparent it could go,” said Liangbing Hu, […]

Biotech Company Granted Ethical Permission To Attempt To Use Stem Cells To Reactivate The Brains Of The Dead

Biotech Company Granted Ethical Permission To Attempt To Use Stem Cells To Reactivate The Brains Of The Dead

A biotech company in the U.S. has been granted ethical permission by an Institutional Review Board in the U.S. and India to use 20 brain-dead patients for what is sure to be a highly controversial study: From next year, they plan to stimulate their nervous systems in order to restart the brains. Bioquark is hoping that its […]

An experimental Alzheimer’s drug reverses genetic changes thought to spur the disease

An experimental Alzheimer’s drug reverses genetic changes thought to spur the disease

Aging takes its toll on the brain, and the cells of the hippocampus—a brain region with circuitry crucial to learning and memory—are particularly vulnerable to changes that can lead to Alzheimer’s disease or cognitive decline. With the hope of counteracting the changes that can lead to these two conditions, researchers at Rockefeller University and their […]

Meet The Nanomachines That Could Drive A Medical Revolution

Meet The Nanomachines That Could Drive A Medical Revolution

A group of physicists recently built the smallest engine ever created from just a single atom. Like any other engine it converts heat energy into movement – but it does so on a smaller scale than seen before. The atom is trapped in a cone of electromagnetic energy and lasers are used to heat it […]

ROOFTOP SOLAR PANELS COULD PROVIDE NEARLY HALF OF OUR POWER

ROOFTOP SOLAR PANELS COULD PROVIDE NEARLY HALF OF OUR POWER

To take advantage of the sun’s energy to satisfy our ever-increasing need for electricity, Americans will have to take a fresh look at their roofs. A report by the National Renewable Energy Laboratory shows that if all suitable roof areas in the United States were plastered with solar panels, they would generate about 1,118 gigawatts […]

Newly discovered magnetism is a big boost for quantum computers

Newly discovered magnetism is a big boost for quantum computers

Until now, humanity has only known two forms of magnetism: ferromagnetism (the kind you see on your fridge) and antiferromagnetism (a sort of negative magnetism found in hard drives). However, MIT researchers just confirmed the existence of a third kind… and it could be the key to making quantum computing a practical reality. The team […]

This scientist found a way to make battery parts with bread mold

Geoff GaddNeurospora growing on a plate. Geoff Gadd, a professor of biology at the University of Dundee in Scotland, learned that when he puts the mold in a container with urea and manganese, a mineral called manganese carbonate will form around the spindly arms of the fungus. The trick works because mold secretes the enzyme […]

How Kinect is helping people to breathe

How Kinect is helping people to breathe

Microsoft’s motion-sensing Kinect peripheral never quite took off as the future of gaming, but it’s proving enduringly popular among scientists as a low-cost imaging device. In the past we’ve seen it used to study glaciers and asteroids, for shopping analytics, in supermarket trolleys and even keeping peace on the Korean border. Now, a team of […]
