Add it up: Could this test equal a way to determine dementia risk?
A new study suggests athletes with a history of concussion may show more brain injury from a later concussion, particularly in middle regions of the brain that are more susceptible to damage, when compared to athletes with no history of concussion.

Climatologist says Canada needs to stop producing fossil fuels within 30 years
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
Damon Matthews, an expert on climate change planning, says getting out of the oil and gas business is necessary for Canada to reach its Paris accord...
One student's mission to protect the world's most precious resource
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
Hooman Chamani, a Ph.D. candidate in Ottawa, is motivated by one thing: To address the global water crisis in an environmentally friendly manner. It may sound simple, but until recently, it was not.
Experts offer tips for preparing kids to go back to school
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...
The strength of new tools in microbiome studies lies in their combined and integrated use
Are you a parent worried about your children going back to school in person after a year and a half of mostly virtual learning?
Protecting the Ozone Layer Also Protects Earth’s Ability to Sequester Carbon
Technology is rapidly evolving across many disciplines. Ground-breaking results are often obtained when new technology enables novel approaches or when technologies are transferred from other fields of research. In a recent review article, Dr. Esther Singer and colleagues explored novel and emerging technologies in relation to plant microbiome research.

Robot mimics the powerful punch of the mantis shrimp
A new study demonstrates how quickly COVID-19 can spread through a household, and provides insight into how and why communities of color have suffered disproportionately from the pandemic.

Biomarker may help predict benefits of immunotherapy
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...

Complex dynamics turn lake water green and brown
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.
LED streetlights contribute to insect population declines: study
Many lakes and ponds are changing colors—from pleasant blue or clear to murky brown or green, caused by runoff of nutrients and carbon, coupled with warmer temperatures.
Underlying instincts: An appetite for survival
Streetlights—particularly those that use white light-emitting diodes (LEDs)—not only disrupt insect behavior but are also a culprit behind their declining numbers, a new study carried out in southern England showed Wednesday.
The boiling crisis and how to avoid it
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...
Team captures data from unarmed Minuteman III test launch
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,"...
Researchers develop method to engineer new cell functionalities on thin films
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.
Physicists make laser beams visible in vacuum
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."
Root cause analysis to probe 'extremely rare' COVID-19 lab error in Sask.
A new method developed at the University of Bonn simplifies ultra-precise adjustment for quantum optics experiments.

Widespread tumor suppression mechanism stops cancer progression by interfering with cancer cell metabolism
New research offers insight into how to treat endometriosis. The researchers performed genetic analyses of humans and rhesus macaques to identify a specific gene, NPSR1, that increases risk of suffering from endometriosis. The results reveal a potential new nonhormonal drug target that may lead to improved therapy.

A Wistar study shows the tumor suppressor Parkin, whose levels are reduced in different cancer types, causes acute metabolic and oxidative stress, suppresses mitochondrial trafficking, and blocks tumor cell movement, reducing primary and metastatic tumor growth.
