University of Lethbridge study finds experimenter’s gender affects rats, could impact study findings – Lethbridge

Lab rodents may have ratted on themselves, exposing they’re not impartial when it comes to their handlers. According to findings from University of Lethbridge researchers, male experimenters create high-anxiety responses in female rats, potentially impacting results in studies. “As a scientist, you’re always concerned about the confounding variables in science, and so we’re looking at … Read more

Chinese scientists allegedly develop a new ‘controllable, reversible’ gene-editing technique

Chinese scientists allegedly develop a new ‘controllable, reversible’ gene-editing technique

“Cas13 can degrade both target and non-target RNAs at random,” making it difficult to design experiments and interpret results when using Cas13, the researchers explained on the CAS website. But “the CRISPR-based gene editing tool does not permanently change the genome, and the effects of editing are controllable, reversible, and safer,” he added. System to … Read more

Crustaceans Discovered ‘Pollinating’ Seaweeds in Scientific First

Crustaceans Discovered ‘Pollinating’ Seaweeds in Scientific First

Pollination is the trademark of flowering plants, with animal pollinators such as bees and birds sustaining the world’s food supplies – not to mention our cravings for coffee, honey, and macadamia nuts. But new research raises the possibility that animal-assisted pollination may have emerged in the sea, long before plants moved ashore. The study, conducted … Read more

Scientists Calculated The Probability of Falling Space Junk Killing Somebody

Scientists Calculated The Probability of Falling Space Junk Killing Somebody

The chance of someone being killed by space junk falling from the sky may seem ridiculously tiny. After all, nobody has yet died from such an accident, though there have been instances of injury and damage to property. But given that we are launching an increasing number of satellites, rockets and probes into space, do … Read more

Do you really need to take 10,000 steps a day?

Do you really need to take 10,000 steps a day?

All models are wrong, the late British statistician George EP Box famously observed, but some are useful. A version of this aphorism often crops up when researchers debate the merits of promoting 10,000 steps a day as a public-health goal. As either a minimum requirement or a guarantee of good health, it’s clearly wrong. But … Read more

There Could Be Planets Orbiting Violent Dead Stars, And Now We Know How to Find Them

There Could Be Planets Orbiting Violent Dead Stars, And Now We Know How to Find Them

Have you heard of LU Camelopardalis, QZ Serpentis, V1007 Herculis, and BK Lyncis? No, they’re not members of a boy band in ancient Rome. They’re Cataclysmic Variables, binary stars that are so close together one star draws material from its sibling. This causes the pair to vary wildly in brightness. Can planets exist in this … Read more

Astronomers Watched a Black Hole Shred a Star – But Surprisingly Little Was Devoured

Astronomers Watched a Black Hole Shred a Star – But Surprisingly Little Was Devoured

What happens when a star wanders too close to a supermassive black hole? The obvious story is that it gets sucked in, never to be seen again. Some of its material gets superheated on the way in and that gives off huge amounts of radiation – usually X-rays. That’s not a wrong explanation, just incomplete. … Read more

A 4-Billion-Year-Old Piece of Earth’s Crust Has Been Identified Beneath Australia

A 4-Billion-Year-Old Piece of Earth’s Crust Has Been Identified Beneath Australia

Scientists can use various clues to figure out what’s under Earth’s surface without actually having to do any digging – including firing super-fine lasers thinner than a human hair at minerals found in beach sand. This technique has been used in a new study that points to a 4-billion-year-old piece of Earth’s crust about the … Read more
