Why do some dogs need high chairs, and how can genetics help?
Some dogs have to eat in a high chair—or, more specifically, a Bailey Chair. The chair keeps them in a vertical position while they eat so that gravity can do the work their bodies can't: moving food from the mouth to the stomach.
Global timekeepers vote to scrap leap second by 2035
Scientists and government representatives meeting at a conference in France voted on Friday to scrap leap seconds by 2035, the organization responsible for global timekeeping said.
NASA Webb micrometeoroid mitigation update
Micrometeoroid strikes are an unavoidable aspect of operating any spacecraft. NASA's James Webb Space Telescope was engineered to withstand continual bombardment from these dust-sized particles moving at extreme velocities, to continue to generate groundbreaking science far into the future.
Citizen science-led expedition retraces the journey of Charles Darwin
Biologist Eduardo Sampaio researched octopuses off Cape Verde. He participated in a Citizen Science-led expedition that retraced the journey of Charles Darwin.
Webb Space Telescope reveals birth of galaxies, how universe became transparent
The earliest galaxies were cosmic fireballs converting gas into stars at breathtaking speeds across their full extent, reports a UCLA-led study to be published in a special issue of The Astrophysical Journal.
Editorial examines challenges of automated facial-expression analysis
As automated facial-expression analysis, or AFEA, becomes increasingly able to recognize facial behavior in everyday life, it will become increasingly important to understand what causes the technology to work incorrectly, as well as anticipate problems that could arise when it does work correctly.
Locking up kids has serious mental health impacts and contributes to further reoffending
Note: This article contains information on violence experienced by First Nations young people in the Australian carceral system. There are mentions of racist terms, and this piece also mentions self harm, trauma and suicide.
Diverting children away from the criminal justice system gives them a chance to 'grow out' of crime
Prison is no place for a child. Putting children in youth justice facilities can have long-lasting consequences for their physical, psychological and emotional health, well-being and development.
'What shall we have for dinner?' Choice overload is a real problem, but these tips will make your life easier
It's been a long day. Your partner messages you: "let's just order in, I don't feel like cooking."
Gender inequality is still rampant in the maritime longshore profession
Gender equality has made enormous strides over the past century. In Canada today, women participate in the labor market at much higher rates than they used to—there are almost 3.5 times more women working now than there were in the 1950s.
Five ways to create a compassionate workplace culture and help workers recover from burnout
We live in tumultuous times which can create an added layer of uncertainty for employees who need to build relationships with students, patients or clients. Providing calm, confident and warm emotional labor can be difficult for people experiencing burnout, grief or compassion fatigue.
As New South Wales reels, many are asking why it's flooding in places where it's never flooded before
On Monday, residents of Eugowra in New South Wales had to flee for their lives. They had only minutes to get to higher ground—or their rooftops—to escape what's been dubbed an "inland tsunami" of water. This week, many other towns across western NSW faced renewed floods. For many people affected, the real shock is how unexpected it was—and how fast the water came. Their houses and land had...
In 2020, universities shifted to online learning. Three lessons from students' experiences
For young people who were in university at the height of the COVID pandemic, the university experience was suddenly radically different to what they had expected.
Young US voters reduced the 'Red Wave' to a 'Pink Splash' in the midterm elections. Why didn't polls predict it?
It increasingly seems that projections of election results based on public polling are unreliable. The 2022 midterm elections in the United States are a prime example.
A nanoscale view of bubble formation: New model describes the boiling process with much greater precision
When a liquid boils in a vessel, tiny vapor bubbles form at the bottom and rise, transferring heat in the process. How these small bubbles grow and eventually detach was previously not known in any great detail.
The Milky Way's mysterious filaments have 'older, distant cousins'
Northwestern University astrophysicist Farhad Zadeh has been fascinated and puzzled by a family of large-scale, highly organized magnetic filaments dangling in the center of the Milky Way ever since he first discovered them in the early 1980s.
Can a universal basic income help address homelessness?
Homelessness is an increasing problem across the developed world, and existing policy responses are failing to make an impact. In Australia, for instance, homelessness has increased despite growing investment in (predominantly crisis-oriented) specialist homelessness services.
How telephone poles could help stop the spotted lanternfly
The Penn State Berks Center for the Agricultural Sciences and a Sustainable Environment (CASSE) is studying the role that telephone poles can play in monitoring and eradicating the invasive spotted lanternfly.
