Accelerating climate modeling with generative AI

Computers and Math from Science Daily Feed - Mon, 12/02/2024 - 12:01pm
The algorithms behind generative AI tools like DallE, when combined with physics-based data, can be used to develop better ways to model the Earth's climate. Computer scientists have now used this combination to create a model that is capable of predicting climate patterns over 100 years 25 times faster than the state of the art.

How a middle schooler found a new compound in a piece of goose poop

Matter and energy from Science Daily Feed - Mon, 12/02/2024 - 12:01pm
A group of young students became bonafide biomedical scientists before they even started high school. Through a partnership with a nearby university, the middle schoolers collected and analyzed environmental samples to find new antibiotic candidates. One unique sample, goose poop collected at a local park, had a bacterium that showed antibiotic activity and contained a novel compound that slowed the growth of human melanoma and ovarian cancer cells in lab tests.

Digital Twins of the Earth is a misleading term as computer models are always a simplified representation of reality

Computers and Math from Science Daily Feed - Mon, 12/02/2024 - 9:40am
The term 'Digital Twin of the Earth' creates the idea of the availability of a highly accurate virtual copy of our planet, enabling researchers to predict the most complex future climate developments and extreme natural events. In fact, such a replica -- or model representation of the Earth systems -- is the goal of the Destination Earth project.

Cooperative motion by atoms protects glass from fracturing

Matter and energy from Science Daily Feed - Mon, 12/02/2024 - 9:40am
You reach for a glass of water only to knock it to the floor, shattering the glass and shooting shards all over the place. If only the glass was unbreakable. Now, researchers have brought this possibility closer to reality after they uncovered crucial insights into how glass becomes more resistant to fractures.

Clay minerals: Researchers observe for the first time how sediment particles align during deposition

Matter and energy from Science Daily Feed - Mon, 12/02/2024 - 9:40am
Clay minerals are a major constituent of the earth's surface and are mainly found in the sediments of lakes, rivers and oceans. The properties of clay and claystone crucially depend on how the tiny sediment particles are orientated. A research team has now succeeded for the first time in observing in detail how some of the processes work.

Public Talk at the University of Michigan Dec 5th

Science blog of a physics theorist Feed - Mon, 12/02/2024 - 9:40am

This week I’ll be at the University of Michigan in Ann Arbor, and I’ll be giving a public talk for a general audience at 4 pm on Thursday, December 5th. If you are in the area, please attend! And if you know someone at the University of Michigan or in the Ann Arbor area who might be interested, please let them know. (For physicists: I’ll also be giving an expert-level seminar at the Physics Department the following day.)

Here are the logistical details:

The Quantum Cosmos and Our Place Within It

Thursday, December 5, 2024, 4:00-5:00 PM ; Rackham Graduate School , 4th Floor Amphitheatre

When we step outside to contemplate the night sky, we often imagine ourselves isolated and adrift in a vast cavern of empty space—but is it so? Modern physics views the universe as more full than empty. Over the past century, this unfamiliar idea has emerged from a surprising partnership of exotic concepts: quantum physics and Einstein’s relativity. In this talk I’ll illustrate how this partnership provides the foundation for every aspect of human experience, including the existence of subatomic particles (and the effect of the so-called “Higgs field”), the peaceful nature of our journey through the cosmos, and the solidity of the ground beneath our feet.

To build better fiber optic cables, ask a clam

Computers and Math from Science Daily Feed - Mon, 12/02/2024 - 9:39am
Since the first fiber optic cables rolled out in the 1970s, they've become a major part of everything from medical devices to high-speed internet and cable TV. But as it turns out, one group of marine mollusks was way ahead of us. A new study reveals that clams called heart cockles have unique structures in their shells that act like fiber optic cables to convey specific wavelengths of light into the bivalves' tissues.
