Creative Minds: Michael Angelo’s Art

Posted by in category: biotech/medical

When you study science, and especially these realms of the biology of what makes us human, what’s clear is that every time you find out something, that brings up ten new questions, and half of those are better questions than you started with.

The artistic masterpiece above, reminiscent of a stained glass window, is the work of Michael Angelo—no, not the famous 16th Century Italian artist, but a 21st Century physician-scientist who’s out to develop a better way of looking at what’s going on inside solid tumors. Called multiplexed ion beam imaging (MIBI), Angelo’s experimental method may someday give clinicians the power to analyze up to 100 different proteins in a single tumor sample.

In this image, Angelo used MIBI to analyze a human breast tumor sample for nine proteins simultaneously—each protein stained with an antibody tagged with a metal reporter. Six of the nine proteins are illustrated here. The subpopulation of cells that are positive for three proteins often used to guide breast cancer treatment (estrogen receptor a, progesterone receptor, Ki-67) have yellow nuclei, while aqua marks the nuclei of another group of cells that’s positive for only two of the proteins (estrogen receptor a, progesterone receptor). In the membrane and cytoplasmic regions of the cell, red indicates actin, blue indicates vimentin, which is a protein associated with highly aggressive tumors, and the green is E-cadherin, which is expressed at lower levels in rapidly growing tumors than in less aggressive ones.

Antarctic Pollution Crisis: Microplastics Found To Be a Greater Threat Than Known

Posted by in category: futurism

Now impacting All Life on Earth.

It’s not the first study on microplastics in Antarctica that researchers from the University of Basel and the Alfred-Wegener Institute (AWI) have conducted. However, data analysis from a spring 2021 expedition reveals that environmental pollution from these tiny plastic particles is a bigger problem in the remote Weddell Sea than was previously known.

The total of 17 seawater samples all indicated higher concentrations of microplastics than in previous studies. “The reason for this is the type of sampling we conducted,” says Clara Leistenschneider, doctoral candidate in the Department of Environmental Sciences at the University of Basel and lead author of the study.

Beyond Transformers: Symbolica launches with $33M to change the AI industry with symbolic models

Posted by in category: robotics/AI

Artificial intelligence startup Symbolica AI launched today with an original approach to building generative AI models.

The company is aiming to tackle the expensive mechanisms behind training and deploying large language models such as OpenAI’s ChatGPT that are based on Transformer architecture.

Alongside that news, it also revealed today that it has raised $33 million in total funding combined from a Series A and seed funding round led by Khosla Ventures. Other investors included Day One Ventures, Abstract Ventures Buckley Ventures and General Catalyst.

Moore’s Law for Everything

Posted by in categories: biotech/medical, economics, law, policy, robotics/AI

Fascinating vision/plan by the one and only Sam Altman of how to update our economic systems to benefit everyone in the context of rapidly accelerating technological change.

My work at OpenAI reminds me every day about the magnitude of the socioeconomic change that is coming sooner than most people believe. Software that can think and learn will do more and more of the work that people now do. Even more power will shift from labor to capital. If public policy doesn’t adapt accordingly, most people will end up worse off than they are today.

We need to design a system that embraces this technological future and taxes the assets that will make up most of the value in that world–companies and land–in order to fairly distribute some of the coming wealth. Doing so can make the society of the future much less divisive and enable everyone to participate in its gains.

Success requires ‘ample doses of pain,’ billionaire Nvidia CEO tells Stanford students: ‘I hope suffering happens to you’

Posted by in category: robotics/AI

When it comes to achieving success, Huang knows more than most. In 1993, he co-founded computer chip company Nvidia, where he’s served as CEO for more than three decades. The company’s success turned Huang into a billionaire. Now, with Nvidia’s chips in high demand for building AI software, it’s become one of the world’s most valuable companies with a valuation north of $2 trillion.

Huang himself is one of the world’s wealthiest individuals, with an estimated net worth of $77.6 billion, according to Bloomberg.

This Tiny Frog Emits a Powerful Ultrasonic Scream No Human Can Hear

Posted by in category: futurism

The Brazilian Atlantic Rainforest is filled with the ear-piercing ‘screams’ of a tiny amphibian in distress, but until now, we humans have been oblivious to their cries.

For the first time, researchers have recorded South American frogs crying out at a frequency that totally bypasses the human ear – but which would be quite unpleasant to animals with the right kind of receivers.

The leaf litter frog (Haddadus binotatus) is the most abundant species of frog in the forest community. Though abundant, they’re tiny – the largest of the species are females, and even they that barely reach 64 millimeters (2.5 inches) in length.
