‘I’m extremely disturbed’: Harsh crackdown at top Iranian university shocks academics worldwide

Sunday’s brutal crackdown against students protesting at one of Iran’s most prestigious universities has shocked Iranian academics and students around the world. The attack, at the Sharif University of Technology in Tehran, also drove home the important role students and universities are playing in the popular uprising against the Iranian government. Protests at many other...

Logging down the value chain raises future forest sustainability concerns

Over a 50-year period, logging on British Columbia's Central Coast preferentially targeted the highest value locations on the landscape, according to new research from Simon Fraser University. The systematic depletion of high-value components of the environment raises concerns about future sustainability and intergenerational access to natural resources.

Researchers develop new tool for targeted cell control

Thanks to new RNA vaccines, we humans have been able to protect ourselves incredibly quickly from new viruses like SARS-CoV-2, the virus that causes COVID-19. These vaccines insert a piece of ephemeral genetic material into the body's cells, which then read its code and churn out a specific protein—in this case, telltale "spikes" that stud the outside of the coronavirus—priming the immune...

Logging down the value chain raises future forest sustainability concerns

Over a 50-year period, logging on B.C.'s Central Coast preferentially targeted the highest value locations on the landscape, according to new research. The systematic depletion of high-value components of the environment raises concerns about future sustainability and intergenerational access to natural resources. Led by SFU PhD graduate Jordan Benner and professor emeritus Ken Lertzman and...

Cleaner, more cost-effective way to make useful industrial chemicals

A team of researchers has developed a new, ecologically sensitive way to produce these nanocrystals through a process called high-humidity shaker aging. The new technique represents an advance over existing methods in that it costs less, uses less water, and eliminates the need for toxic solvents, all while producing higher yields.

The surprising Swiss-Army-knife-like functions of a powerful enzyme

Blue-green algae (AKA cyanobacteria) have a superpower which likely helps them be highly successful as invaders of waterways. They have an extraordinary ability to store energy and nitrogen in their cells for times of need. But how exactly they do so remains only partly understood. Now researchers have uncovered an intriguing hitherto unknown ability of the enzymes (known as cyanophycin...

Glass microspheres won't save Arctic sea ice

A proposal to cover Arctic sea ice with layers of tiny hollow glass spheres about the thickness of one human hair would actually accelerate sea-ice loss and warm the climate rather than creating thick ice and lowering the temperature as proponents claim. Sea ice, by reflecting the majority of the sun's energy back to space, helps regulate ocean and air temperatures and influences ocean...

Study shows challenge of promoting citizen science to help prevent disasters caused by flooding

An application developed in collaboration with vulnerable communities to transmit early warnings of the risk of floods and environmental disasters has become public policy in Brazil, and the methodology is being replicated for use elsewhere. With practical results obtained in 2022, part of the discussions involving proposals to improve flood risk governance began at least two years ago.

The porcelain challenge didn’t need to be real to get views

Despite what you may have heard, the teens are not stealing their family’s fine dinnerware, tossing it in a blender, and snorting the resulting dust for the “porcelain challenge.” That’s just what Sebastian Durfee, a 23-year-old actor and TikTok creator, hoped you might believe when he spread the word on social media of the latest dangerous teen challenge.  Never mind that it was...

RNA origami enables applications in synthetic biology

Developing tools for precise control of biological processes has been one of the main pillars of the now mature field of synthetic biology. These scientific tools borrow principles from a multitude of research fields which, when combined, enable unique applications that are potentially transformative for the modern society.

Birdsong reveals rare hybrid coupling 10 million years in the making

In June of 2020, Stephen Gosser, a self-described "diehard birder," was out in the woods of Western Pennsylvania when he thought he heard the song of the elusive and strikingly beautiful scarlet tanager. The blood-red bird with black wings and tail is a favorite among birders for both its beauty and rarity, as the birds prefer to stay hidden high in the forest canopy.

Empathizing with the opposition may make you more politically persuasive

Trying to understand people we disagree with can feel like an effort hardly worth making, particularly in contentious political environments in which offering even the smallest olive branch to the opposition can be perceived as betraying our own side. Research in Psychological Science, however, suggests that cross-partisan empathy may actually make our political arguments more persuasive, rather...

Department of Energy requires plans to promote diversity from grant applicants

Researchers seeking funding from the United States’s single biggest funder of the physical sciences will now have to think about how they can structure their own efforts to promote greater participation by researchers and students of color and from other underrepresented groups. This week, the Department of Energy’s (DOE’s) Office of Science, which has an annual budget of...

Petting dogs engages the social brain, according to neuroimaging

Researchers report that viewing, feeling, and touching real dogs leads to increasingly higher levels of activity in the prefrontal cortex of the brain. The study shows that this effect persists after the dogs are no longer present, but is reduced when real dogs are replaced with stuffed animals. The findings have implications for animal-assisted clinical therapy.

College student 'Fear of Missing Out' (FoMO) associated with illicit behavior

The fear of missing out (FoMO) on rewarding and fun experiences is something that most people feel at some point in life. Among college students, the degree to which someone experiences FoMO is associated with their risk of participating in maladaptive behaviors including academic misconduct, drug and alcohol use, and breaking the law, according to a new study.

Drug could be ‘gamechanger’ for people with chronic coughs

Gefapixant could be first new cough drug to be approved in UK for more than 50 years, says lung doctorA new drug to treat chronic coughs could be a “gamechanger” treatment for the thousands of Britons who cough uncontrollably, many times a day.The leading lung doctor Surinder Birring has led a global trial that found Gefapixant reduces a person’s coughing by up to 60% and brings some relief...

Catch-and-release fishing may cause temperature spikes in sharks

New research from marine scientists raises potential red flags for sharks that are caught and released by recreational anglers. The team has discovered that the ocean's iconic predators typically spike in temperature after they have been caught, which may have physiological and behavioral impacts.

Sound reveals giant blue whales dance with the wind to find food

A study by MBARI researchers and their collaborators published today in Ecology Letters sheds new light on the movements of mysterious, endangered blue whales. The research team used a directional hydrophone on MBARI's underwater observatory, integrated with other advanced technologies, to listen for the booming vocalizations of blue whales. They used these sounds to track the movements of blue...
