Science Magazine — Personal DNA sequencing once promised to up the ante for individualized medicine. Perhaps no one believed that more than human genomics pioneer J. Craig Venter, who in 2014 co-founded a company called Human Longevity to predict and prevent disease by sequencing a million human genomes. But Venter is no longer content with your DNA.

New 3D scanning campaign will reveal 20,000 animals in stunning detail

New 3D scanning campaign will reveal 20,000 animals in stunning detail

Science Magazine — Known as the "Fish Guy," Adam Summers earned his moniker for an odd hobby turned academic obsession: giving dead fish a computerized tomography, or CT, scan.

Elderly chimps may get Alzheimer's, renewing interest in studying these animals

Science Magazine — Researchers have discovered tell-tale signs of Alzheimer's disease in 20 elderly chimpanzee brains, rekindling a decades-old debate over whether humans are the only species that develop the debilitating condition. Whether chimps actually succumb to Alzheimer's or are immune from symptoms despite having the key brain abnormalities is not clear.

Memory-enhancing drug reverses effects of traumatic brain injury in mice

Science Magazine — Whether caused by a car accident that slams your head into the dashboard or repeated blows to your cranium from high-contact sports, traumatic brain injury can be permanent. There are no drugs to reverse the cognitive decline and memory loss, and any surgical interventions must be carried out within hours to be effective, according to the current medical wisdom.

Science Magazine — Leroy Hood knows a thing or two about disruptive technologies. One of biology's living legends, the now 78-year-old scientist played an influential role in the development of the first automated DNA sequencer. He pioneered systems biology, the study of interactions of molecular networks, and still leads an institute devoted to it in Seattle, Washington.

MIT Technology Review — At least 351 U.S. businesses are offering unproven stem cell interventions in clinics across the country, claiming to treat everything from arthritis to Alzheimer's, according to a paper published Thursday in the journal Cell Stem Cell. The finding casts light on an emerging area of medical treatment that has received little attention from the U.S.

Minerals formed due to people's activity may mark Anthropocene epoch

Chemical & Engineering News — The latest evidence that people are refashioning Earth is written not in the sky, where carbon dioxide levels are rising, nor in the acidifying ocean, but in stone. Geologists have identified about 200 minerals that formed due to the hustle and bustle of human activity.

Roadkill to drug discovery

Roadkill to drug discovery

Chemical & Engineering News — When driving down Highway 9 in Norman, Okla., Robert H. Cichewicz pays special attention to grisly sights of matted fur and dried blood that most people try to avoid seeing-but don't manage to avoid hitting. Cichewicz is a natural products chemist at the University of Oklahoma who scours the molecular makeups of fungi and bacteria to find potential drug candidates.
