Canadians who rely on Line 5 on edge as Michigan's deadline looms to shut Enbridge pipeline
Southern Ontario workers who benefit from Enbridge's Line 5 are anxiously watching what's playing out this week in Michigan, which has given the Calgary-based firm until Wednesday to shut down the pipeline — a move backed by Indigenous groups, but would cut off a major source of fuel for Ontario and...
Graphene key for novel hardware security
- ScienceDaily
- 21/5/10 23:19
As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components to create secure keys, but artificial intelligence (AI) techniques can be used to predict these keys and gain access to data. Now, researchers have designed a way to make the...
NASA's OSIRIS-REx spacecraft begins its 2-year trip home with asteroid debris
With rubble from an asteroid tucked inside, a NASA spacecraft fired its engines and began the long journey back to Earth on...
Crew training begins soon for first private trip to ISS
Training of the crew for the first entirely private trip to the International Space Station (ISS) is to begin soon, Axiom Space, the company behind the flight, said Monday at a joint press conference with NASA.
Drone video shows endangered whales appearing to embrace
Were these whales really hugging—or was it just a fluke?
NASA spacecraft begins 2-year trip home with asteroid rubble
With rubble from an asteroid tucked inside, a NASA spacecraft fired its engines and began the long journey back to Earth on Monday, leaving the ancient space rock in its rearview mirror.
Even when they include them, gifted programs aren't serving Black or low-income kids
After years of criticism for their lack of diversity, programs for high achievers may not be adequately serving their Black and low-income students, a new study shows.
Informed tourists make whale watching safer for whales
According to the International Whaling Commission, whale-watching tourism generates more than $2.5 billion a year. After the COVID-19 pandemic, this relatively safe outdoor activity is expected to rebound. Two new studies funded by a collaborative initiative between the Smithsonian Tropical Research Institute (STRI) in Panama and Arizona State University (ASU) show how science can contribute to...
Geoscientists find that shallow wastewater injection drives deep earthquakes in Texas
In a newly published paper, Virginia Tech geoscientists have found that shallow wastewater injection—not deep wastewater injections—can drive widespread deep earthquake activity in unconventional oil and gas production fields.
'Flipping' optical wavefront eliminates distortions in multimode fibers
The use of multimode optical fibers to boost the information capacity of the Internet is severely hampered by distortions that occur during the transmission of images because of a phenomenon called modal crosstalk.
Caldera collapse increases the size and duration of volcanic eruptions
Scientists have figured out what triggers large-scale volcanic eruptions and what conditions likely lead to them.
Invasive species alters marine community, interferes in post-disaster recovery
Clavelina oblonga, an invasive marine fouling species, not only reduces diversity in communities it invades, it also interferes in their recovery following natural disasters—a process known as "succession."
Nasa craft carrying 4.5bn-year-old asteroid dust begins long trek home
Scientists believe the dust sample may provide clues on the formation of the Solar System.

The first nationwide study of outcomes for different gifted subgroups shows the programs may not be adequately serving their Black and low-income students.
Time running out to save coral reefs
- ScienceDaily
- 21/5/10 22:15
New data on the growth rates of coral reefs shows there is still a window of opportunity to save them from eroding by mid-century -- but time is running out.
Ocean-bottom sediments tell a story about ancient Greenland summers
- ScienceDaily
- 21/5/10 22:15
The study uses leaf wax chemicals in the deposits to learn about ancient climate in southern Greenland, focusing on summer temperature during periods of relative warmth on Earth, called interglacials, over the past 600,000 years.
Animal production responsible for vast majority of air quality-related health impacts from U.S. food
- ScienceDaily
- 21/5/10 22:15
Poor air quality caused by food production in the U.S. is estimated to result in 16,000 deaths annually, 80% of which are related to animal production, according to a new study. The study also shows how improving animal and crop management practices, as well as how eating more plant-rich diets, can substantially reduce mortality from food-related air pollution.
'Flipping' optical wavefront eliminates distortions in multimode fibers
- ScienceDaily
- 21/5/10 22:15
Researchers have devised a novel technique to 'flip' the optical wavefront of an image for both polarizations simultaneously, so that it can be transmitted through a multimode fiber without distortion.
Intoxication brings strangers physically closer
- ScienceDaily
- 21/5/10 22:14
In a study with pandemic-related implications, researchers report that strangers who consume alcohol together may keep their distance initially -- but draw physically closer as they become intoxicated.
Turns out developing a taste for carbs wasn't a bad thing
- ScienceDaily
- 21/5/10 22:14
A new study looking at the evolutionary history of the human oral microbiome shows that Neanderthals and ancient humans adapted to eating starch-rich foods as far back as 100,000 years ago, which is much earlier than previously thought.
PARP inhibitor shrinks tumors in pancreatic cancer patients with mutations
- ScienceDaily
- 21/5/10 22:14
More than two-thirds of pancreatic cancer patients harboring genetic mutations saw their tumor stop growing or shrink substantially after being switched from intensive chemotherapy to the PARP inhibitor rucaparib as a maintenance therapy.
Stimulators could aid spinal cord, heart therapies
- ScienceDaily
- 21/5/10 22:14
Engineers develop a new version of their wireless implant that allows for multiple stimulators to be programmed and magnetically powered from a single transmitter outside the body. The implants could be used to treat spinal cord injuries or as pacemakers.
For twins, gesture and speech go hand-in-hand in language development
- ScienceDaily
- 21/5/10 22:14
Twins produce fewer gestures and gesture to fewer objects than other children. Language use also lags for twins, and language -- but not gesture -- is also affected by sex, with girls performing better than boys.
