4:00 PM | Genetic Analysis Of 110-Year-Olds Finds No Secret
You Don't Have to Be Super-Healthy to Be a Supercentenarian But you do have to have the right genes. U.S. Census Bureau, Public Information Office (PIO) Is the secret to long life in a gene? We don't know, for now. A recent project to read the entire DNA sequence of 17 people aged 110 or older has found… there's nothing particularly different from ordinary folks. It is known that super-longevity is inheritable. It runs in families. An analysis of […]

10:08 PM | IBM's Watson Will Give You Health Advice Based On Your DNA
DNA Richard Wheeler via Wikimedia Commons Maybe you have a fitness tracker. Maybe you've gotten your genome sequenced before. Probably your medical records are kept in electronic, instead of paper, form. Now some companies are seeking to combine all those things and more into a talking, personalized, health-advice app. Not sure when to give yourself your next insulin shot after having a croissant for breakfast? You can ask the app. How much exercise should someone with […]

8:05 PM | Kitty DNA Shows Cats Have Evolved To Learn From Treats
Samantha J. Kitty, Domesticated Cat Evan Kafka via Suzanne LaBarre A cat can't tell you much about its history (mrow?) but its genetics can. Today, an international team of geneticists is publishing the most thorough read yet of the DNA of a domestic cat. This is the first time scientists have read the cat genome carefully enough to tease out details about how evolution—and humans—have changed them. The team found evidence that a combination of evolution and […]

9:45 PM | Where Do Genitals Come From?
House Snake Embryo, Six Days Old Patrick Tschopp, PhD; Harvard Medical School, Department of Genetics Whence your phallus? You probably have one—the term includes clitorises as well as penises—and, until now, scientists had never examined which cells in an embryo make it. In biology, that's unusual. Tracking which embryonic cells become what body part is an important part of figuring out the basic rules for making life. For example, scientists know, in […]

Sniff Test This is a nose model the Oregon Healthy Authority uses for educational presentations. Oregon Health Authority A pair of scientists say they've figured out how to make the smell equivalent of "white noise." They've written the equations. Now what's left is to make a device that's able to cancel out everything from onions to locker-room musk, although it's unclear whether such a machine will ever be made. "Olfactory white" works differently from […]

6:00 PM | How To Give A Mouse Ebola
Emerging Diseases Lab, University of Washington This lab was one of several that worked on making the Ebola-symptom mice described below. Brian Donohue If you give a lab mouse the mouse version of Ebola, it will die. But not in the same way humans with Ebola do. Lab mice infected with Ebola don't get hemorrhagic fever. They don't form tiny clots in their blood, like human Ebola sufferers do, even though the genetic sequence of the mouse Ebolavirus differs from human […]

8:00 PM | '3-D Cutter' Othermill Goes On Sale
An Othermill Other Machine Co. You can think of an Othermill as the opposite of a 3-D printer. Instead of building up objects from raw materials, Othermills create objects by cutting away a larger block of material into something smaller. They're like tiny robotic sculptors, similar to the artists who chisel away at a big block of marble until it becomes a work of art. Like home 3-D printers, however, Othermills are made to fit on a tabletop. And they've gone on […]

8:30 PM | Can Robots Help Fight Ebola?
Helping Hand Takao Someya Group/University of Tokyo Engineers make disaster-response robots precisely because robots are able to work in situations that are too dangerous for humans. Now the humans have got a new idea: Perhaps robots could carry off waste from Ebola patients, or bury the bodies of people who have died from Ebola in West Africa. Roboticizing such tasks would keep people from having to touch bodies when they're most infectious. Working with the White […]
