Perfluoroalkyl substances (PFAS) are highly versatile chemicals. These fluorine-containing organic molecules are the reason why rain drops simply slide off outdoor jackets. They are used in the greaseproof coating of paper food packaging and are key ingredients in fire-extinguisher foams and the protective gear worn by firefighters. PFAS were first introduced in the 1940s and since then, the number of products and areas in which they are used has grown astronomically.

Now, in a paper published today in Nature Communications, Nanglu and his co-authors report that the exquisitely-preserved 500-million-year-old fossil is a dead ringer for some tunicates today, with two siphons to filter organic particles from the water and complex musculature controlling the siphons. “It looks like a tunicate that died yesterday and just happened to fall down on some rock,” says Nicholas Treen, a developmental biologist at Princeton University who wasn’t involved in the work.

The disease was diagnosed in the Australian rules footballer Heather Anderson, who died at age 28 in November, a paper outlining the postmortem analysis said.

Companies making cultured meat are attracting billions of dollars of investment. Here are their biggest challenges.

Summary:

• Lab-grown meat could be available to consumers by 2023
• Don't expect the first available lab-grown meat to be affordable
• Growing meat from cells is difficult. Researchers are trying to 1) find the optimal starter cells, or 2) use immortal cells (think HeLa) which should be safe
• Conventional feed/culture for research labs come from cows, so ppl are developing plant-based alternatives. Unfortunately every company is using their own proprietary solution
• Health issues pertinent to meat will still be present, although lab-grown will be much better to animal welfare
• Lab-grown meat will take up far less land, but require a lot more energy per kilo compared to even beef

TL;DR
UCSF researchers injected monkeys with a protein named "klotho" that has links to aging but its function is unknown. The group already did this in mice, this time they did it in monkeys; low-dose injection caused monkeys to do better on cognitive tasks.

I don't know what klotho is or why only low-dose injection worked but... I have never seen a study like this that actually worked before, so this is new and interesting to me. Interestingly this article has like one experiment but went into Nature Aging which is... quite surprising to me.

As a deadly heat wave continues to ravage the U.S., new evidence suggests the human body may stop functioning optimally when outside temperatures climb to 104 to 122 degrees Fahrenheit.

Research presented Thursday at the annual Society for Experimental Biology conference in Edinburgh, Scotland, suggests that temperatures in that range raise a person's resting metabolic rate — the amount of energy needed to function at rest.

Although the sun provides nearly all the energy needed to warm the planet, its contribution to climate change remains widely questioned. Many empirically based studies claim that it has a significant effect on climate, while others (often based on computer global climate simulations) claim that it has a small effect.

“Dung beetles spend hours rolling up balls of dung to attract females,” he said. “But there are some very smart dung beetles that just sit by the side and watch while others do hard work. Then they shoot in, take the dung ball, take the girl and run away with everything. That’s Joe Biden.”

A way to passively achieve cooling below ambient temperature, using non-toxic common chemicals. 40 minute video, but very informative.

Scientists at the US National Centers for Environmental Prediction said that the world's average temperature had reached 17.01C on 3 July, breaking the previous record of 16.92C that had stood since August 2016.

The development of neural networks to create artificial intelligence in computers was originally inspired by how biological systems work. These "neuromorphic" networks, however, run on hardware that looks nothing like a biological brain, which limits performance.

In today's payment ecosystem, customers' sensitive data is substituted by sequences of random numbers, and the uniqueness of each transaction is secured by a classical cryptographic method or code. However, adversaries and merchants with powerful computational resources can crack these codes and recover the customers' private data, and for example, make payments in their name.

For enabling absolute secure digital payments, the scientists replaced classical cryptographic techniques with a quantum protocol exploiting single photons (particles of light). During the course of a classical digital payment transaction the client shares a classical code—called cryptogram—with their payment provider (e.g. a bank or credit card company).

This cryptogram is then passed on between customer, merchant and payment provider. In the demonstrated quantum protocol this cryptogram is generated by having the payment provider sending particularly prepared single photons to the client.

For the payment procedure, the client measures these photons whereby the measurement settings depend on the transaction parameters. Since quantum states of light cannot be copied, the transaction can only be executed once. This, together with the fact that any deviation of the intended payment alters the measurement outcomes, which are verified by the payment provider, makes this digital payment unconditionally secure.

The researchers successfully implemented quantum-digital payments over an urban optical fiber link of 641m, connecting two university buildings in down-town Vienna. Digital payments currently operate within a few seconds.

This study investigates effects of climate change on compound drought and heat wave (CDHW) events. CDHW events involve prolonged hot temperatures and water shortages, which can obviously worsen each other's impacts. Examples: California wildfires in 2020 and Australian bushfires in 2019-2020.

In the worst-case scenario, by the late 21st century, approximately 20% of global land areas could experience two CDHW events per year, lasting 25 days and becoming four times more severe.

Vulnerable regions that are expected to see the largest increases in CDHW frequency: eastern North America, southeastern South America, Central Europe, East Africa, Central Asia, and northern Australia.

The silent mPFC engram cells gradually mature into active engram cells (activatable by natural recall cues) during the weeks after learning and this maturation process requires post-training input from the hippocampal engram cells. Thus, we propose that SCM occurs in two major steps: the rapid generation of a silent engram in the mPFC during learning and the slow functional maturation of these engrams aided by input from hippocampal engram cells during the post-training period lasting a few weeks in rodents.
