The Perseid meteor shower hits its peak on Aug. 12-13, bringing with it a torrent of shooting stars along with the potential for spectacular fireball sightings. The Perseids are one of the most highly anticipated shooting star displays of the year. However, the 2025 shower happens to coincide with the rise of a waning gibbous moon, the glare from which …

Topline A “planet parade” is building in the eastern sky before sunrise this week — and the highlight comes on Tuesday, Aug. 12. Best seen about an hour before sunrise, as the peak of the Perseid meteor shower draws to a close, bright planets Jupiter and Venus will appear less than one degree from each other in the eastern sky. …

A study published in PeerJ by paleontologists Sven Sachs and Daniel Madzia has reclassified a nearly complete plesiosaur skeleton found in 1978 in Holzmaden, Germany, as a new genus and species. Named Plesionectes longicollum, this Early Jurassic marine reptile had an extraordinarily long neck and unique skeletal features that challenge previous ideas about plesiosaur evolution during the Toarcian stage, about …

After 10 years without sight, a Victoria, B.C., woman saw her partner’s face and her dog’s wagging tail this year for the very first time, thanks to a tooth surgically implanted into her eye socket.  Gail Lane, 75, was one of three Canadians to undergo the rare tooth-in-eye surgery, technically called osteo-odonto keratoprosthesis, in February. Lane lost her sight ten years ago due to …

Topline Early risers this month can see a “planet parade” building in the eastern sky before sunrise featuring Saturn, Jupiter, Venus and Mercury. Best seen about an hour before sunrise, on Monday, Aug. 11, Saturn will be visible in the south, with bright planets Jupiter and Venus in the east. Mercury may also be glimpsed below Venus and Jupiter as …

1.Today, we all know that an asteroid killed/started the extinction of the dinosaurs. The theory was first proposed in 1980 by Nobel prize laureate physicist Luis Alvarez and his geologist son Walter. They suggested that a massive asteroid impact about 66 million years ago caused sudden climate changes that wiped out most dinosaur species. Evidence for this came from a …

A new study by researchers at Northwestern University has set off alarm bells about the future of academic research, warning that the publication of fraudulent science is growing at a faster rate than that of legitimate research. Over the last four centuries, an implicit contract has been established between scientists and states: in exchange for producing knowledge useful for economic …

But Whitehouse presented a third line of evidence to dispute the 3.95 billion-year date: isotopes of hafnium in the same zombie zircon crystals. The technique relies on radioactive decay of lutetium–176 to hafnium–176. If the 2.8-billion-year age resulted from rejuvenation by later heating, it would have had to have formed from material with a hafnium isotope ratio incompatible with the …
