When a woman undergoes weight loss surgery, her own body isn't the only one affected: children born to women after they've undergone gastric bypass procedures exhibit key genetic differences compared to siblings born prior to the surgeries.
That's according to a small new study published in PNAS...
New research raises weighty questions
Japanese researchers have demonstrated a new type of resin that could be used in 3D micro-electrodes that interface with the brain. With the material, it's possible to micro-sculpt tiny objects that hold their shape after being "carbonized" at 800...
A mystery is unfolding in the laboratories and grain fields of Oregon. Stalks of wheat that hadn't been planted and wouldn't die were found growing among a farmer's crops. Tests have revealed that the peculiar wheat included an illegal gene modification that made it resistant to a certain herbicide — something that shouldn't have existed within a commercial US grain field. Now the USDA's...
Researchers at the US Department of Energy’s Lawrence Berkeley National Laboratory have captured the moment when atoms form a covalent bond. The team happened upon the discovery by accident: they set out to build graphene nanostructures, and used an atomic force microscope to ensure they had correctly arranged the atoms. Much to their surprise, the microscope captured some stunning images of carbon atoms and their bonds.
"We weren't thinking about making beautiful images... but to really see what was happening at the single-atom level we had to use a uniquely sensitive atomic force microscope," explains Felix Fischer, a scientist who worked on the project. "Nobody has ever taken direct, single-bond-resolved images of individual molecules, right before and immediately after a complex organic reaction." As Berkeley Lab's News Center...

Over the past decade, DARPA’s work on brain-controlled prosthetic limbs has led to some impressive breakthroughs, but with the development of novel neuromuscular interfaces, it’s making real headway toward mainstream bionic limbs in the near term. Today, the agency released some new...
A French company will be moving forward with implanting a new artificial heart that incorporates biological tissue from a cow. Earlier this month Carmat won approval from four different cardiac centers in Saudi Arabia, Slovenia, Poland, and...
Private companies trying to shuttle tourists into space. Audacious plans to send civilians on a one-way mission to Mars. Astronauts recording David Bowie cover songs from 230 miles above the Earth. Nope, space travel isn't what it used to be.
