A new study provides a potential tool for unraveling the mystery of how experiences can cause inheritable changes to an animal's biology. By mating nematode worms, they produced permanent epigenetic changes that lasted for more than 300 generations.

Recess quality, not just the amount of time spent away from the classroom, plays a major role in whether children experience the full physical, mental and social-emotional benefits of recess, a new study has found.
Human cells: To splice or not to splice. ..
- ScienceDaily
- 21/7/9 15:44
Scientists investigated the efficiency of splicing across different human cell types. The results were surprising in that the splicing process appears to be quite inefficient, leaving most intronic sequences untouched as the transcripts are being synthesized. The study also reports variable patterns between the different introns within a gene and across cell lines, and it further highlights the...
Some assembly required: How a cellular machine builds itself
As you read this text, the millions of cells that make up your body are hard at work. Within every cell is a flurry of activity keeping you alive, mostly driven by machinery that is made up of proteins. Some of this protein machinery is so important to living things that it has remained unchanged over millions of years of evolution.
Songbird ancestors evolved a new way to taste sugar
Humans can easily identify sweet-tasting foods—and with pleasure. However, many carnivorous animals lack this ability, and whether birds, descendants of meat-eating dinosaurs, can taste sweet was previously unclear. An international team of researchers led by Maude Baldwin of the Max Planck Institute for Ornithology has now shown that songbirds, a group containing over 4.000 species, can sense...
Scientists create genetic library for mega-ecosystem in Pacific Ocean
The California Current extends nearly 2,000 miles from Canada's Vancouver Island to the middle of the Baja Peninsula in Mexico. It brings cold water from the North Pacific Ocean to the west coast of North America and is home to numerous and abundant species because of the upwelling of deep nutrient-rich waters.
Opening protected area off New England coast to commercial fishing compromises protections
A study published this week in the scientific journal Frontiers in Marine Science found that opening the 3.14 million acre Northeast Canyons and Seamounts Marine National Monument to commercial fishing reduces species protection in the richly diverse and vital ecological area.
'Return to normal' travel and research may bring hazards to northern, Indigenous communities
Throughout the pandemic, many have longed for a "return to normal." When the threat of COVID-19 subsides, we look forward to resuming our research and travel schedules, and reclaiming the elements of our lives that were disrupted over a year ago. However, for southern-based researchers and travelers, returning to northern, Indigenous communities either for leisure or research fieldwork in summer...
Potential treatment for stroke, brain injury studied with help from Saskatoon's synchrotron
Researchers from the University of Saskatchewan, the University of Oxford and Columbia University have come together share their...
If you’re going to put your preschooler in front of a screen, choose a TV. Here’s why | Sophie Brickman
Screens aren’t all the same. When it comes to cognition, there are big differences between an iPad and a televisionFor her first few years of life, my daughter Ella likely thought the television played a single piece of content: the 1993 version of George Balanchine’s Nutcracker, starring as the title role one Macaulay Culkin, who spends the majority of the ballet running around stage and...
The neuroscience behind why your brain may need time to adjust to ‘un-social distancing’ | Kareem Clark
If the idea of small talk at a crowded happy hour sounds terrifying to you, you’re not alone. Nearly half of Americans reported feeling uneasy about returning to in-person interaction regardless of vaccination statusWith Covid vaccines working and restrictions lifting across the country, it’s finally time for those now vaccinated who have been hunkered down at home to ditch the sweatpants and...
Northern Manitoba First Nation aims to help feed community, fight diabetes with expanded vertical farm project
A northern Manitoba community has turned to technology to help grow veggies year-round — part of an expansion of a project that aims to generate health, economic and environmental benefits in the...
Interactive police line-ups improve eyewitness accuracy: study
Eyewitnesses can identify perpetrators more accurately when they are able to manipulate 3D images of suspects, according to a new study.
Match matters: The right combination of parents can turn a gene off indefinitely
Evidence suggests that what happens in one generation—diet, toxin exposure, trauma, fear—can have lasting effects on future generations. Scientists believe these effects result from epigenetic changes that occur in response to the environment and turn genes on or off without altering the genome or DNA sequence.
Virgin Galactic, Blue Origin face off in space tourism market
The era of space tourism is set to soar, with highly symbolic flights by rivals Virgin Galactic and Blue Origin scheduled just days apart.
Space, the final frontier for billionaire Richard Branson
As famous for his thrill-seeking lifestyle and publicity stunts as for his vast business empire, Richard Branson has set his sights on the stars as he prepares for liftoff on his first space flight.

Two vessels, two companies, with one goal: blasting their billionaire founders into space.
FAA: New tool limits disruptions caused by space operations
Federal regulators said Thursday they now can better track rocket launches and space vehicles returning to Earth, which could cut the amount of time that airplanes must be routed around space operations.
