#paleoctober2025 day 6 : Ichthyotitan severnensis !

Triassic ichthyosaurs are quite something, having in their ranks some of the biggest marine vertebrates of all time. Althought this one is only known from partial jaw remains, it's estimated to be nearly 25m long.

Association of air pollution exposure and genetic susceptibility with increased risk of thoracic aortic aneurysm and dissection - Nature Cardiovascular Research Ma et al. demonstrate that air pollution is associated with an increased risk of thoracic aortic aneurysm and dissection (TAAD), and that genetic susceptibility to TAAD amplifies this risk through multiplicative and additive interactions.

Record heat now outnumbers record cold by more than 3 to 1 in the US. In a normal climate, they’d be equal. After billions of years of natural hot & cold cycles, human forcing has now overtaken nature as the longterm driving force of our present & future climate.

Manuscript page by astronomer William Herschel, describing how his telescopes penetrate into time as well as into space.

Last week I came across a remarkable archival document by astronomer William Herschel. He describes his telescopes as time machines, capable of "penetrating into time" as much as 1,910,000 years into the past.

His numbers were off, but his insight was spot on. In the year 1800!

#Erin intensified from a Tropical Storm to a Cat 4 in 24 hours… Talk about rapid intensification! 75 mph jump!
Over the past few decades RI has increased a few mph each decade so storms now can intensify an extra 20+ mph more in the same time frame, likely due to warming waters.

Why winter rains keep skipping the Southwest » Yale Climate Connections Human-caused climate change from burning fossil fuels may be involved in a persistent tilt toward dry patterns.

NOAA has just issued a La Niña Watch for late 2025/early 2026. So far this century, we've had 12 La Niña winters versus just 8 El Niño winters. What does this portend for Southwest US drought? There's some unsettling new science out on that.

The marine heat wave in the North Pacific is one of the most extensive, spanning the giant N Pacific, and in spots, the most intense, I’ve observed. Anomalies near Japan are 15 F (8C) above normal. (Japan just recorded its hottest temp on record.)

Low-dose metformin requires brain Rap1 for its antidiabetic action Metformin lowers blood glucose by inhibiting Rap1 in ventromedial hypothalamic neurons that regulate glucose balance.

Metformin, the first line drug for Type 2 diabetes, has been used for 60 years without a clearcut mechanism of action. It turns out it's not just reducing glucose output from the liver. Metformin also works via the brain www.science.org/doi/10.1126/...

The Earth has two massive 'superplumes' rising beneath Africa and the Pacific, surrounded by about ten mantle plumes each.
These antipodal magma domes are the origin of some of the most ferocious volcanic hotspots on the planet.

It’s not coincidence, it’s climate change.
Research shows a huge increase since the 1980s.
In fact, the long-term warming trend explains over 90% of the increase in MHW frequency, intensity, and duration. #EU #Europe

The Atlantic's chilling secret: A century of data reveals ocean current collapse A century-old mystery of a stubborn cold patch in the North Atlantic is finally being unraveled. A new study links this anomaly to a long-term weakening of the Atlantic Meridional Overturning Circulat...

A study confirms what we have long argued: the spectacular Atlantic 'cold blob' is the result of a slowing of the Atlantic overturning circulation #AMOC, which transports warm waters into that region. That's the only part of Earth that resisted #globalwarming. 🌊
