Human Exceptionalism In Evolution: How We Walked Upright

Science 2.0 - Sep 02 2025 - 10:09
One key hallmark of being human is walking on two legs. It was a seismic shift seen in no other primates. Like much of evolution, it happened in fits and starts. The 4.4 million year-old Ardipithecus of Ethiopia was a tree climber with a grasping toe that would walk upright 3.2 million year old Lucy had a pelvis brought upright walking closer, with flaring hip blades for bipedal muscles.

Some of that legacy remains in our closest relatives, the African apee, e.g. chimpanzees, bonobos, and gorillas, have upper hipbones (ilia) that are tall, narrow, and oriented flat front to back which anchor large muscles for climbing.

Searching For Impossibly Rare Decays

Science 2.0 - Sep 01 2025 - 09:09
I recently ran into a description of the Mu3e experiment, and got curious about it and the physics it studies. So after giving it a look, I am able to explain that shortly here - I think it is a great example of how deep our studies of particle physics are getting; or, on the negative side, how deep our frustration has gotten with the unassailable agreement of our experiments with Standard Model predictions.

Adam Smith And The Transactional Fallacy

Science 2.0 - Aug 28 2025 - 19:08

A guest on NPR’s Morning Edition (August 26) mis-characterized pioneering economist Adam Smith as a pure transactionalist. Smith’s metaphorical “invisible hand,” the guest asserted, suggested self-interest drives our every action. It’s a big deal – in fact, a revelation! – she continued, that Smith lived with his mother, and that Mom cooked Adam’s meals and washed his laundry for him, unpaid and with Adam oblivious to her role in his theory. The invisible hand, she concluded, ignored familial love as a motive for action.

Trump's 'No Surprises Act' Reduced Patient Out-Of-Pocket Expenses

Science 2.0 - Aug 28 2025 - 12:08
Health care is expensive. If you are convinced that donating blood is a community service and do it for free, the Red Cross sells it for up to $200 per pint. If you need a transfusion, each pint will cost $1,000 and up. That is paid for by insurance. What isn't covered by insurance will be passed along to you in the form of an out-of-pocket cost. If you have a medical emergency and an ambulance you did not request takes you to a hospital outside your network, you could be bankrupt. All due to federal government poiicies that began to create the health care problem in the 1940s and have only added on to it since.

How The Ancient Volcanoes Of Ultima Thule Impacted Climate Then And Now

Science 2.0 - Aug 27 2025 - 15:08
Some sixty million years ago a fountain of hot rock that rises from Earth’s core-mantle boundary unleashed volcanic activity across a vast area of the North Atlantic, from Scotland to Greenland. We can detect the effects in spectacular basalt columns of the Giant’s Causeway in Ireland.

But why Iceland’s fiery mantle plume had such a dramatic impact has been the subject of debate.

40% Of Advanced Cancer Patients Are Ignored On Their Care Goals

Science 2.0 - Aug 27 2025 - 14:08
Advanced cancer often brings preparation for the worst and proponents of the modern health care system use terms like "advocate" and "empowered" when everyone who isn't part of the system knows patients have trouble doing the former and certainly are not the latter.

Government, health insurers, and hospitals make the real decisions, and even if that goes your way doctors may do what they want. That is why nearly 40% say their wishes are ignored when it comes to their care goals.

Knucklehead Democrats

Science 2.0 - Aug 27 2025 - 09:08

"Knucklehead" and “Wimp” were the toss-up for titling today’s column.

A few Democrat politicians are almost heroic as they respond to the current sh*tshow in Washington: Corey Booker, Elizabeth Warren, Robert Reich, JB Pritzker, Melanie Stansbury, AOC, and even Adam Schiff and Jamie Raskin, and occasionally Amy Klobuchar.

A Remarkable Graph: The Full Dalitz Plot Of Neutron Decay

Science 2.0 - Aug 26 2025 - 10:08
The neutron is a fascinating particle, and one which has kept experimental physicists busy for almost a century now. Discovered by James Chadwick in 1932 in a cunning experiment which deserves a separate post (it is a promise, or a threat if you prefer),  the neutron has been all along a protagonist in the development of nuclear weapons as well as in the extraction of nuclear power from fission reactors. And of more relevance to our discussion here, it has powered endless studies both in the context of nuclear and subnuclear physics.

What To Do If The Dog Gets Into Your Cocaine

Science 2.0 - Aug 25 2025 - 11:08
Cocaine toxicosis in animals is a real thing. You shouldn't do cocaine, even during the Biden administration it didn't become legal and it's more dangerous than that kratom people buy in a gas station. Drug dealers secretly despise their customers so it could adulterated with lots of bad things.

But you make a choice to be a moron, your pet is mostly a walking libido.

Mummy Mia! Medicinal Cannibalism Was More Recent Than You Think

Science 2.0 - Aug 23 2025 - 05:08

Why did people think cannibalism was good for their health? The answer offers a glimpse into the zaniest crannies of European history, at a time when Europeans were obsessed with Egyptian mummies.

Driven first by the belief that ground-up and tinctured human remains could cure anything from bubonic plague to a headache, and then by the macabre ideas Victorian people had about after-dinner entertainment, the bandaged corpses of ancient Egyptians were the subject of fascination from the Middle Ages to the 19th century.

Mummy mania

Faith that mummies could cure illness drove people for centuries to ingest something that tasted awful.
