The discovery could lead to developing a drug that can trigger regrowth of damaged nerves. Spinal cord injuries are currently irreparable. Most people who suffer from such an injury never fully recover, and many end up with partial or even full paralysis. Although we’ve made great strides in understanding how spinal injuries damage nerves and […]
The prospect of yeast-by-design is tantalizing for many researchers in the brewing industry. Man-made yeasts could irreversibly change everything from the biofuel to the brewing industry. A team of geneticists led by Jef Boeke at Johns Hopkins University is genetically engineering a yeast from scratch, as part of the Synthetic Yeast 2.0 project. They have designed and written […]
Researchers embedded carbon nanotubes in the chloroplasts of the plants to create “artificial antennae.” Plants make life possible. Chloroplasts are the tiny organelles with a plant’s leaves. The chloroplasts use incoming sunlight to split water molecules and then knit together the energy-rich carbon and hydrogen compounds found in everything from food to fossil fuels. The […]
Physicists create a device that binds photons together to form “light molecules.” A vacuum chamber the size of a shoebox has made history in Cambridge, Massachusetts. Harvard physicist Ofer Firstenberg has created a new form of matter: a pair of photons, stuck together.
Diamond sample containing the hydrous ringwoodite. The Earth’s transition zone is the part of the Earth that exists between the upper and lower mantle. Scientists often theorize what lies in the transition zone. Many believe that the transition zone contains a lot of water, but there was no proof to support that idea. A group […]
The discovery of cannabinoid receptors may help explain why marijuana users say they take the drug mainly to reduce anxiety. Researchers at Vanderbilt University have found cannabinoid receptors, through which marijuana exerts its effects, in a key emotional hub in the brain involved in regulating anxiety and the flight-or-fight response.
Stem cell therapy could be used to help older patients recover from muscular injuries. People become less able to bounce back from injuries as they age. This is a problem that adds risk to many of the common medical procedures the elderly face. At the same time, stem cells’ greatest promise is to allow people […]
A switch in the brain sends us off to sleep. In a study in fruit flies, researchers at Oxford University’s Centre for Neural Circuits and Behavior have identified a switch in the brain that sends us off to sleep.
A Nanoscribe 3D printer can print models of the Empire State building in a space the width of a human hair using precision lasers. Watching the machine build through the “lens” of an electron microscope is otherworldly—but the printer’s potential runs beyond microscale model making. (Video)
