Aspiring bakers are frequently called upon to adapt award-winning recipes based on differing kitchen setups. Someone might use an eggbeater instead of a stand mixer to make prize-winning chocolate chip cookies, for instance.

Being able to reproduce a recipe in different situations and with varying setups is critical for both talented chefs and computational scientists, the latter of whom are faced with a similar problem of adapting and reproducing their own “recipes” when trying to validate and work with new AI models. These models have applications in scientific fields ranging from climate analysis to brain research.

“When we talk about data, we have a practical understanding of the digital assets we deal with,” said Eliu Huerta, scientist and lead for Translational AI at the U.S. Department of Energy’s (DOE) Argonne National Laboratory. “With an AI model, it’s a little less clear; are we talking about data structured in a smart way, or is it computing, or software, or a mix?”

Early on Thursday morning, Hurricane Nicole made landfall near Vero Beach on Florida’s eastern coast. Because Nicole had a very large eye, nearly 60 miles in diameter, its strongest winds were located well to the north of this landfalling position.

As a result of this, Kennedy Space Center took some of the most intense wind gusts from Nicole late on Wednesday night and Thursday morning. While such winds from a Category 1 hurricane are unlikely to damage facilities, they are of concern because the space agency left its Artemis I mission—consisting of the Space Launch System rocket and Orion spacecraft—exposed on a pad at Launch Complex-39B. The pad is a stone’s throw from the Atlantic Ocean.

How intense were the winds? The National Weather Service hosts data from NASA sensors attached to this launch pad’s three lighting towers on a public website. It can be a little difficult to interpret the readings because there are sensors at altitudes varying from 132 feet to 457 feet. Most of the publicly available data appears to come from an altitude of about 230 feet, however, which would represent the area of the Space Launch System rocket where the core stage is attached to the upper stage. The entire stack reaches a height of about 370 feet above the ground.

For the past two centuries, humans have relied on fossil fuels for concentrated energy; hundreds of millions of years of photosynthesis packed into a convenient, energy-dense substance. But that supply is finite, and fossil fuel consumption has tremendous negative impact on Earth’s climate.

“The biggest challenge many people don’t realize is that even nature has no solution for the amount of energy we use,” said University of Chicago chemist Wenbin Lin. Not even photosynthesis is that good, he said: “We will have to do better than nature, and that’s scary.”

One possible option scientists are exploring is “artificial photosynthesis”—reworking a plant’s system to make our own kinds of fuels. However, the chemical equipment in a single leaf is incredibly complex, and not so easy to turn to our own purposes.

Climate change delegates traveling aboard private jets known to release more carbon dioxide emissions have added to the controversy surrounding the United Nations Climate Change Conference (COP27) in Sharm el-Sheikh, Egypt.

Hundreds of environmental activists stopped private jets from taking off from Amsterdam’s Schiphol Airport the day before the conference started last week.

“We face two global crises in housing and climate change.”

Southern California met its first-in-the-world 3D-printed zero net home thanks to Mighty Buildings. As part of a 40-unit community in Desert Hot Springs, these 3D-printed houses also draw attention to environmental and economic strategies.

“We are excited to be the first company in the world to complete what we believe to be the sustainable housing standard of the future,” said Mighty Buildings CEO Slava Solonitsyn, as per Dezeen.

Nature is (actually) healing.

Thanks to effective bans of harmful chemicals, the hole in the ozone keeps getting smaller.

A spectacular and explosive volcanic eruption in January 2022 produced the highest plume of steam and ash in recorded history.

The towering column that arose from Hunga Tonga-Hunga Ha’apai reached a tremendous altitude of 57 kilometers (35 miles) above sea level.

A recently released set of topography maps provides new evidence for an ancient northern ocean on Mars. The maps offer the strongest case yet that the planet once experienced sea-level rise consistent with an extended warm and wet climate, not the harsh, frozen landscape that exists today.

“What immediately comes to mind as one the most significant points here is that the existence of an ocean of this size means a higher potential for life,” said Benjamin Cardenas, assistant professor of geosciences at Penn State and lead author on the study recently published in the Journal of Geophysical Research: Planets.

Demand is growing for effective new technologies to cool buildings, as climate change intensifies summer heat. Now, scientists have just designed a transparent window coating that could lower the temperature inside buildings, without expending a single watt of energy. They did this with the help of advanced computing technology and artificial intelligence. The researchers report the details today (November 2) in the journal ACS Energy Letters.

Cooling accounts for about 15% of global energy consumption, according to estimates from previous research studies. That demand could be lowered with a window coating that could block the sun’s ultraviolet and near-infrared light. These are parts of the solar spectrum that are not visible to humans, but they typically pass through glass to heat an enclosed room.

Energy use could be even further reduced if the coating radiates heat from the window’s surface at a wavelength that passes through the atmosphere into outer space. However, it’s difficult to design materials that can meet these criteria simultaneously and at the same time can also transmit visible light, This is required so they don’t interfere with the view. Eungkyu Lee, Tengfei Luo, and colleagues set out to design a “transparent radiative cooler” (TRC) that could do just that.
