Physicists have linked the Doppler effect to heat transport, suggesting wave-like properties in biological tissues, with implications for medical and cosmetic technologies.

When a train approaches or an ambulance with its siren blaring nears us, we hear the sound with an increased frequency, which gradually decreases. As it passes, the frequency changes abruptly to a lower one, then decreases further. This commonly encountered phenomenon, known as the Doppler effect, can offer valuable insights into a seemingly unrelated field: heat transport.

The Physics of Heat Transport.

What if symptoms of chronic pain were sometimes just echoes of a past injury, and your brain could “snap out of it” with the help of psychedelics? It’s a surprising theory that several labs around the world are beginning to investigate. While there have been few double-blind, placebo-controlled, randomized clinical trials evaluating the efficacy of psychedelics for treating chronic pain, preliminary evidence is beginning to emerge — with promising results.

Chronic pain is defined as pain that persists beyond the usual recovery period or occurs with another condition. It may occur continuously or happen off and on. The most common manifestations of chronic pain are lower back pain, headache disorders, fibromyalgia, and neuropathic pain. People treated for chronic pain often undergo “pain management programs” that combine approaches from different fields to customize treatments.

Although it may be a reflection of ongoing physical health issues, chronic pain can also have deeply psychosomatic origins, reflecting the close relationship between mind and body.

Listen to this episode from Carboncopies Podcast on Spotify. In the third episode of the Carboncopies Podcast Series, Professor Tony Zador presents his work in DNA barcoding and projectome mapping. This technique has already been utilized by the well known Allen Brain Atlas. Zador further presented a nascent extension of this work that offers the possibility of using the same basic technique to map connectomes.

The big question is whether the wealth boom of the past decade, initially fueled by low interest rates and liquidity, and more recently by Covid-19 pandemic stimulus and artificial intelligence, can continue. Global conflicts, elections, interest rates and a potential economic slowdown could all slow the pace of wealth creation, said Elias Ghanem, global head of the Capgemini Research Institute for Financial Services.

“The last 10 years were exceptional,” Ghanem said. “We now have inflation, a potential recession and geopolitical problems and elections. The environment is completely different.”

Indeed, globally, the wealth picture looks more mixed than in the U.S. The number of millionaires worldwide grew 5.1% last year, to 22.8 million, according to the report. Their combined fortunes grew to a record $86.8 trillion.

Ancient vessels, discovered by accident on the Mongolian steppe, have given us new insight into how the land’s ancient inhabitants ate.

Archeologists have scraped caked residue from the insides of two Bronze Age cauldrons dating back 2,750 years, revealing that the vessels were once used for collecting the blood of ruminants, such as sheep and goats, as well as the milk of wild yaks (Bos mutus).

What did they do with the blood, you ask? Well, we can’t know for certain, but it was likely used for dietary purposes, such as the production of blood sausage, similar to sausage-making techniques still used in rural Mongolia today.
