Add it up: Could this test equal a way to determine dementia risk?

People whose scores on a dementia risk test indicated a less brain-healthy lifestyle, including smoking, high blood pressure and a poor diet, may also have the following: lower scores on thinking skills tests, more changes on brain scans and a higher risk of cognitive impairment, according to a new study.

Engineers are 'driving' innovation to help eliminate plastic waste

Each year in the United States, millions of tons of plastic waste are discarded and not recycled, leading to serious environmental problems. In an effort to help keep this waste from ending up in the environment, engineers at the University of Missouri are partnering with Dow and the Missouri Department of Transportation (MoDOT) to test mixing plastic waste into the asphalt pavement mixtures for...

How a Japanese far-right hate group helped popularize anti-Korean sentiment

Studies show that anti-Korean sentiment in Japan has grown steadily in the past decade, despite the growing acceptance of more visibly "foreign" Southeast Asian migrants in Japan. A University of Notre Dame researcher conducted two years of ethnographic fieldwork in a historic Korean ghetto in Osaka, Japan, to shed light on the legacy of discrimination that third- and fourth-generation Korean...

Robot mimics the powerful punch of the mantis shrimp

Mantis shrimp pack the strongest punch of any creature in the animal kingdom. How mantis shrimp produce these deadly, ultra-fast movements has long fascinated biologists. Now, an interdisciplinary team of roboticists, engineers and biologists have modeled the mechanics of the mantis shrimp's punch and built a robot that mimics the movement. The research sheds light on the biology of these...

Biomarker may help predict benefits of immunotherapy

A group of researchers reported that a specific pattern, or 'signature,' of markers on immune cells in the blood is a likely biomarker of response to checkpoint immunotherapy. Within this immune signature, a molecule LAG-3 provided key information identifying patients with poorer outcomes.

Underlying instincts: An appetite for survival

Microscopic roundworms may hold the key to understanding what is happening in the brain when the instinct of an animal changes in order to survive. In a newly published paper in the journal Current Biology, University of Rochester Medical Center researchers found that a signaling system in the brain changes to redirect the behavior of an animal when their survival is at risk because there is not...

The boiling crisis and how to avoid it

It's rare for a pre-teen to become enamored with thermodynamics, but those consumed by such a passion may consider themselves lucky to end up at a place like MIT. Madhumitha Ravichandran certainly does. A Ph.D. student in Nuclear Science and Engineering (NSE), Ravichandran first encountered the laws of thermodynamics as a middle school student in Chennai, India. "They made complete sense to me,"...

Team captures data from unarmed Minuteman III test launch

A team from Lawrence Livermore National Laboratory (LLNL) successfully collected data from the recent operational test of an Air Force Global Strike Command unarmed Minuteman III intercontinental ballistic missile (ICBM) launched from Vandenberg Space Force Base.

Researchers develop method to engineer new cell functionalities on thin films

Researchers at the Institute of Molecular Biology (IMB) and Johannes Gutenberg University Mainz (JGU) have developed a method to engineer new functionalities into cells. The results were published today in the journal Cell in the article "Dual film-like organelles enable spatial separation of orthogonal eukaryotic translation."
