A new way to store thermal energy

MIT researchers create material for a chemical heat ‘battery’ that could release its energy on demand In large parts of the developing world, people have abundant heat from the sun during the day, but most cooking takes place later in the evening when the sun is down, using fuel — such as wood, brush or … Continue reading “A new way to store thermal energy”

Why Head and Face Pain Causes More Suffering

People consistently rate pain of the head, face, eyeballs, ears and teeth as more disruptive, and more emotionally draining, than pain elsewhere in the body. Duke University scientists have discovered how the brain’s wiring makes us suffer more from head and face pain. The team found that sensory neurons that serve the head and face … Continue reading “Why Head and Face Pain Causes More Suffering”

CRISPR-carrying nanoparticles edit the genome

New delivery system developed by MIT team deletes disease-causing genes and reduces cholesterol. In a new study, MIT researchers have developed nanoparticles that can deliver the CRISPR genome-editing system and specifically modify genes in mice. The team used nanoparticles to carry the CRISPR components, eliminating the need to use viruses for delivery. Using the new … Continue reading “CRISPR-carrying nanoparticles edit the genome”

How a $10 Microchip Turns 2-D Ultrasound Machines to 3-D Imaging Devices

Doctors and engineers from Duke and Stanford universities have developed a technology for turning a 2D untrasound machine into something closer to a 3D imaging device such as CT Scan and MRI. Technology that keeps track of how your smartphone is oriented can now give $50,000 ultrasound machines many of the 3-D imaging abilities of … Continue reading “How a $10 Microchip Turns 2-D Ultrasound Machines to 3-D Imaging Devices”

Scientists Created Low-Fat Pigs by Editing Their Genes With CRISPR

Chinese scientists have created low-fat pigs using new genetic engineering techniques. In a paper published in the Proceedings of the National Academy of Sciences, the scientists report that they have created 12 healthy pigs with about 24 percent less body fat than normal pigs. The scientists created low-fat pigs in the hopes of providing pig … Continue reading “Scientists Created Low-Fat Pigs by Editing Their Genes With CRISPR”
