People who regularly use psychoactive substances report experiencing a variety of negative impacts since the COVID-19 pandemic began, including increased usage and fear of relapse or overdose, highlighting the need for improved supports and services, including better access to safe supply programs, according to a new CAMH survey published in the International Journal of Drug Policy.

Engineered, autonomous machines combined with artificial intelligence have long been a staple of science fiction, and often in the role of villain like the Cylons in the "Battlestar Galactica" reboot, creatures composed of biological and engineered materials. But what if these autonomous soft machines were ... helpful?

Researchers have developed new x-ray optics that can be used to harness extremely fast pulses in a package that is significantly smaller and lighter than conventional devices used to modulate x-rays. The new optics are based on microscopic chip-based devices known as microelectromechanical systems (MEMS).

Research from the the University of Pennsylvania and Children's Hospital of Philadelphia points to the involvement of the immune system the brain as a contributor to mental disorders such as schizophrenia.

A new study out of West Virginia University suggests that rural e-cigarette users are older--and often get sicker--than their urban counterparts.

A new study led by University of Washington researchers borrowed image-analysis methods from engineering to spot the minute movements of a stony coral.

Researchers at the University of Jyväskylä, Finland, highlight how the struggles caused by the COVID-19 pandemic can guide us towards an equitable use of our shared environment and a transition towards sustainability.

Mass extinctions are known as times of global upheaval, causing rapid losses in biodiversity that wipe out entire animal groups. Some of the doomed groups linger on before going extinct, and a team of scientists found these "dead clades walking" (DCW) are more common and long-lasting than expected.

Hongbo Pang from the U of M College of Pharmacy found a better drug delivery system to treat prostate cancer and bone growth.

Concern tends to ratchet up a notch when pollution enters the river runoff discussion on a national scale, specifically when smaller, navigable intrastate bodies of water push pollution into larger interstate waters often involved in commerce (i.e. the Mississippi River, Great Lakes, Ohio River).

An expansive project led by Michigan State University's Lars Brudvig is examining the benefits, and limits, of environmental restoration on developed land after humans are done with it.

A chemist from Purdue University has found a way to synthesize a compound to fight a previously "undruggable" cancer protein with benefits across a myriad of cancer types.

The observation that most of the viruses that cause human diseases come from other animals has led some researchers to attempt "zoonotic risk prediction" to second-guess the next virus to hit us. However, in an Essay publishing in journal PLOS Biology, led by Dr Michelle Wille at the University of Sydney, Australia with co-authors Jemma Geoghegan and Edward Holmes, it is proposed that these zoonotic risk predictions are of limited value and will not tell us which virus will cause the next pandemic.

Mice study offers a new working hypothesis on how a small brain region in the hypothalamus may control female sexual behaviour.

Using a widely known field of mathematics designed mainly to study how digital and other forms of information are measured, stored and shared, scientists at Johns Hopkins Medicine and Johns Hopkins Kimmel Cancer Center say they have uncovered a likely key genetic culprit in the development of acute lymphoblastic leukemia (ALL).

The federal government, in its response to the COVID-19 pandemic, could learn from how the nation responded to Hurricane Katrina, 9/11 and the H1N1 swine flu, a new study found.

New research from Boston Medical Center identifies elevated mortality risk for women with back pain when compared to women without back pain. Back pain was not associated with mortality among men indicating long-term consequences of back pain may differ by sex.

When hydraulic fracturing operations ground to a halt last spring in the Kiskatinaw area of British Columbia, researchers expected seismic quiescence in the region. Instead, hundreds of small earthquakes occurred for months after operations shut down, according to a new study.

The famous 1700 Cascadia earthquake that altered the coastline of western North America and sent a tsunami across the Pacific Ocean to Japan may have been one of a sequence of earthquakes, according to new research presented at the Seismological Society of America (SSA)'s 2021 Annual Meeting.

Earthquake early warnings can be delivered successfully using a small network of off-the-shelf smartphones attached to building baseboards, according to a study conducted in Costa Rica last year.
