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)
A nanomotor inside a HeLa Cell. A Pennsylvania State University team has discovered that nanomotors made from tiny metal rods can be manipulated by sound waves and magnets, giving them precise control over their actions inside of cells.
A nicotine patch could be used for the treatment of neurological disorders, including Parkinson’s, mild cognitive impairment, ADHD, Tourette’s, and schizophrenia. Dan Hurley, author of Smarter: The New Science of Building Brain Power, is on a quest to make his brain work better. He is looking into the evidence for why nicotine may be the […]
A demonstration of two sugar biobatteries connected in a series to power a digital clock. Almost all living cells break down sugar to produce energy. Researchers at Virginia Tech say they have developed a battery that can store the most energy for its weight using sugar as a fuel source by mimicking what plants and […]
Breastfeeding is an important strategy to ensure a healthy balance of good bacteria in an infant’s gut. Babies have legions of microbes that set up shop in their guts, skin, and more right from birth. These microbes are vital. They help the growing human to digest its food, and to keep harmful microbes away. They […]
Discoveries in the field of telomere biology will have an impact on how we can stay young naturally and look younger than our chronological age. Research in telomere biology has the potential to extend human life span, to dramatically lower rates of the great remaining killer diseases: heart disease, stroke, and Alzheimer’s. All three diseases […]
A new wrinkle in the control of waves. Flexible, layered materials textured with nanoscale wrinkles could provide a new way of controlling the wavelengths and distribution of waves, whether of sound or light. The new method, developed by researchers at MIT, could eventually find applications from nondestructive testing of materials to sound suppression, and could […]
Nearly all technological advances in the past century or more have depended on our ability to produce and manipulate the vast variety of materials that nature has given us. Nowhere is this more evident than in the field of electronics. From a smorgasbord of semiconductors, polymers, and metals, we’ve been able to create a dazzling […]
