Researchers confirm brightest gamma-ray burst of all time came from the collapse of a massive star

Artist’s visualization of GRB 221009A showing the narrow relativistic jets—emerging from a central black hole—that gave rise to the GRB and the expanding remains of the original star ejected via the supernova explosion. Using the James Webb Space Telescope, Northwestern University postdoctoral fellow Peter Blanchard and his team detected the supernova for the first time, … Read more

Fewer showers, less laundry, as water cuts hit Bogota

Some 10 million people in the Colombian capital and surrounds will be impacted by measures which started Thursday and impose 24-hours of no water every ten days, according to the sector they live in. Residents of Bogota are facing fewer showers, minimal laundry loads and dirty cars as the Colombian capital imposes water rations due … Read more

New study finds potential targets at chromosome ends for degenerative disease prevention

Telomeres are found at the ends of chromosomes and play a critical role in the cell-renewal process. Credit: National Human Genome Research Institute We depend on our cells being able to divide and multiply, whether it’s to replace sunburnt skin or replenish our blood supply and recover from injury. Chromosomes, which carry all of our … Read more

Unraveling the song of ice and fire across the American landscape with machine learning

A recent study published in Advances in Atmospheric Sciences explores the intriguing relationship between wildfires in the West and hailstorms in the Central US. At the … Read more

Tens of billions of dollars in forest products are being overlooked

Credit: Unsplash/CC0 Public Domain In the Roman Empire, custom taxes on spices, black pepper in particular, accounted for up to a third of the empire’s annual income. During the late Middle Ages, European efforts to cut out middlemen and monopolize the spice trade led to colonization in Asia. Historically, non-timber forest products have frequently played … Read more

‘Branded access offers’ dilute parent brand via perceived lack of consumer commitment: Study

Credit: Pixabay/CC0 Public Domain Why buy when you can rent? From cars to high-end clothing, the short-term renting or sharing of consumer goods through “branded access offers” has become an increasingly popular alternative to the traditional ownership model. But such time-limited consumption may have unintended consequences for the parent brands that offer them, according to … Read more

Innovation linked to international exports for both rural and urban firms

Credit: Pixabay/CC0 Public Domain A new study led by Penn State researchers finds that U.S. firms actively engaged in creating innovative products or processes are more likely to expand into international markets. The findings, which apply to both rural and urban companies, could inform efforts to boost U.S. exports. The team—led by Luyi Han, a … Read more

Study proposes large-scale biomanufacturing workflow to produce natural killer cells and extracellular vesicles

HFB-produced NK92 cells yielded large quantities of small NK92-EVs. Credit: Journal of Extracellular Vesicles (2023). DOI: 10.1002/jev2.12387 A team of uOttawa Faculty of Medicine researchers have developed a path to a biomanufacturing process that could potentially transform how Canada generates immunotherapeutic materials—specifically natural killer cells and extracellular vesicles (EVs)—to fuel tomorrow’s novel cancer treatments. How … Read more

Juice aces Callisto flyby test

One of the computer-generated images of Jupiter’s moon Callisto that was used to test the capabilities of Juice’s engineering model in March 2024. When Juice’s flight model passes the real Callisto in 2031 and offers scientists a tantalising glimpse at the mysterious, cratered alien world, this is how it will appear to the spacecraft’s navigation camera.
