AI tool maps out cell metabolism with precision

AI tool maps out cell metabolism with precision

Understanding how cells process nutrients and produce energy—collectively known as metabolism—is essential in biology. Modern biology generates large datasets on various cellular activities, but integrating and analyzing the vast amounts of data on cellular processes to determine metabolic states is a complex task.

What a submerged ancient bridge discovered in a Spanish cave reveals about early human settlement

What a submerged ancient bridge discovered in a Spanish cave reveals about early human settlement

A new study led by the University of South Florida has shed light on the human colonization of the western Mediterranean, revealing that humans settled there much earlier than previously believed. This research, detailed in a recent issue of the journal, Communications Earth & Environment, challenges long-held assumptions and narrows the gap between the settlement timelines of islands throughout the Mediterranean region.

Groups of weaver birds found to have their own distinct nest-building styles

Groups of weaver birds found to have their own distinct nest-building styles

A team of biologists in the U.K. and Canada has found that at least one type of bird has its own distinct nest building style. In their study, published in the journal Science, the group conducted a two-year study of nest-building by sparrow weavers in the Kalahari Desert.

Solar Orbiter shows how solar wind gets a magnetic push

Solar Orbiter shows how solar wind gets a magnetic push

ESA's Solar Orbiter spacecraft has provided crucial data to answer the decades-long question of where the energy comes from to heat and accelerate the solar wind. Working in tandem with NASA's Parker Solar Probe, Solar Orbiter reveals that the energy needed to help power this outflow is coming from large fluctuations in the sun's magnetic field.

Researchers present new diagnostic tool for laser-plasma accelerator using metal foil as 3D scanner

Researchers present new diagnostic tool for laser-plasma accelerator using metal foil as 3D scanner

Laser-plasma accelerators take up less space than conventional facilities, which are sometimes kilometers long. Such compact particle sources can accelerate electron bunches efficiently, enabling X-ray lasers that fit in the basement of a university institute.

Using a gamma ray burst to search for violations of Einstein's relativity postulates

Using a gamma ray burst to search for violations of Einstein's relativity postulates

Einstein's theory of relativity is based on two assumptions, or postulates. The first is that the laws of physics look the same to everyone traveling in a straight line with no acceleration.

Geophysicist's method could give months' warning of major earthquakes

Geophysicist's method could give months' warning of major earthquakes

The public could have days or months of warning about a major earthquake through identification of prior low-level tectonic unrest over large areas, according to research by a University of Alaska Fairbanks scientist who analyzed two major quakes in Alaska and California.

Scientists discover molecular mechanism that plays key role in gene transcription and macrophage functional activation

Scientists discover molecular mechanism that plays key role in gene transcription and macrophage functional activation

As the largest variant of the histone H2A family, macroH2A plays significant regulatory roles in various processes such as X-chromosome inactivation, embryonic development, cellular metabolism, and tumorigenesis due to its unique linker and macro domains.

Enhancing microbe memory to better upcycle excess CO₂

Enhancing microbe memory to better upcycle excess CO₂

While some microbes can make people sick or spoil food, others are critical for survival. These tiny organisms can also be engineered to make specific molecules. Researchers reporting in ACS Sustainable Chemistry & Engineering have rewired one such microbe to help tackle greenhouse gases in the atmosphere: It takes in carbon dioxide (CO2) gas and produces mevalonate, a useful building block for pharmaceuticals.
