New ‘Remarkable Connection’ Discovered Between Our Heart And Brain

Posted by in category: neuroscience

In the few seconds it will take you to read this sentence, your sense of time may expand and contract, and your perception of the world could shift in ways you wouldn’t notice.

These subtle effects on the brain are imperceptible, ethereal tugs from the heart beating away inside your chest which, according to a new study, boosts motor function in short bursts too.

Neuroscientist Esra Al of the Max Planck Institute for Human Cognitive and Brain Sciences in Germany has been studying the heart’s influence on the brain for several years, building upon decades-old research and recent studies with more robust methods.

Perspective: The Rise of “Wet” Artificial Intelligence

Posted by in categories: biotech/medical, business, robotics/AI

Combining AI with traditional wet lab work creates a virtuous circle from lab to data and back to the lab.

AI, with the right data, can span all of these scales and make sense of the data we collect on all of them. It’s poised to accelerate basic science, the business of biotechs, the behemoth pharmaceutical companies, and the broader bioeconomy.

Computers, cars, mobile phones, toasters: countless everyday objects contain microchips. They’re tiny, unremarkable and cheap, but since the outbreak of the coronavirus pandemic, they’ve been at the center of a political and industrial tug of war.

Against the backdrop of the trade war between China and the US, “The Microchip War” spotlights all the aspects of this conflict. In the film, the world’s most influential actors in this industrial sector weigh in.

The first results from the world’s biggest basic income experiment

Posted by in categories: business, economics, education, finance

One of the big questions GiveDirectly is trying to answer is how to direct cash to low-income households. “Just give cash” is a fun thing to say, but it elides some important operational details. It matters whether someone gets $20 a month for two years or $480 all at once. Those add up to the same amount of money; this isn’t a Side Hustle King situation. But how you get the money still matters. A certain $20 every month can help you budget and take care of regular expenses, while $480 all at once can give you enough capital to start a business or another big project.

The latest research on the GiveDirectly pilot, done by MIT economists Tavneet Suri and Nobel Prize winner Abhijit Banerjee, compares three groups: short-term basic income recipients (who got the $20 payments for two years), long-term basic income recipients (who get the money for the full 12 years), and lump sum recipients, who got $500 all at once, or roughly the same amount as the short-term basic income group. The paper is still being finalized, but Suri and Banerjee shared some results on a call with reporters this week.

By almost every financial metric, the lump sum group did better than the monthly payment group. Suri and Banerjee found that the lump sum group earned more, started more businesses, and spent more on education than the monthly group. “You end up seeing a doubling of net revenues” — or profits from small businesses — in the lump sum group, Suri said. The effects were about half that for the short-term $20-a-month group.

Why It’s Hard to Break Plastics

Posted by in category: materials

The crack resistance of polymer materials is explained by a new model that incorporates a network of stretchable polymer chains.

Plastics and other polymer materials are often very resistant to cracking—a fact that models have not been able to accurately capture. Now a research team has developed a model of polymer fracture that explains how these materials remain intact under intense stretching. [1]. The key to the model is that it accounts for polymer chains that extend deep within the material and that can share the strain that would break a material with more localized chains. The insights could lead to the development of new structures with an enhanced resistance to shocks.

Researchers typically study fracture by cutting a small notch or crack into a material and then pulling it apart. The amount of work required to enlarge the crack is called the fracture energy. For most materials, the fracture energy is equal to the energy it takes to break the molecular bonds located along the crack tip, where the enlargement occurs. For polymers, the situation is more complex, as the molecules are long chains. In the 1960s, theorists came up with a model of polymer fracture based on the rupture of individual chains at the crack tip [2]. “The problem is that this model underestimates by a factor of 10 to 100 the energy required to fracture a polymer material,” says Xuanhe Zhao from the Massachusetts Institute of Technology.
