Three-dimensional fossil algae more than 541 million years old reveal a modern-looking ancestry of the plant kingdom

Reconstruction of a cross-section through Protocodium sinense, showing likeness to modern Codium. Credit: Shu Chai Paleontologists have identified a new genus and species of algae called Protocodium sinense that predates the origin of land plants and modern animals and provides new insight into the early diversification of the plant kingdom. Discovered at a site in … Read more

Researchers reveal the origin of ultrafast mystery signals in valleytronic materials

By exciting the transitional metal dichalcogenide monolayers—atomically thin semiconductors—with ultrashort pump pulses, atoms can coherently vibrate and modulate optical responses. The probe pulses can detect the ultrafast modulation that shows peculiar high-frequency overtones of K-point acoustic phonons. Credit: Yokohama National University Tiny materials hold big mysteries, the solutions to which could bring about next-generation electronics. … Read more

Scientists reveal method of converting methane gas into liquid methanol

The conversion took place under ambient temperature and pressure conditions, which could enable methane, a potent greenhouse gas, to be used to produce fuel. Credit: UFSCAR A group of researchers has succeeded in converting methane into methanol using light and dispersed transition metals such as copper in a process known as photo-oxidation. According to an … Read more

AI can reveal new cell biology just by looking at images

AI learned how to recognize and classify different dog breeds from images. A new machine learning method from CZ Biohub now makes it possible to classify and compare different human proteins from fluorescence microscopy images. Credit: CZ Biohub Humans are good at looking at images and finding patterns or making comparisons. Look at a collection … Read more

Scientists reveal garden eels’ unique way of feeding

Garden eels anchor the lower part of their body in burrows, and face their heads against the current as they prey on zooplankton. The species pictured is the spotted garden eel, Heteroconger hassi.

As Webb begins observing exoplanets, scientists use Spitzer data & brown dwarfs to reveal how silicate clouds form

In a new study from a group of researchers in Canada, data from NASA’s now-retired Spitzer Space Telescope was used to determine the conditions under which silicate clouds form on distant exoplanets outside of our solar system — giving scientists insight into what’s inside the atmospheres of exoplanets similar in size, temperature, and composition to … Read more

Genome of tropical freshwater fish may reveal conservation clues

DePaul researchers will create a high-quality reference genome for two species of the endemic characid genus Rhoadsia and conduct resequencing of 20 additional specimens. Credit: Windsor Aguirre The genetic evolution of freshwater fish in Ecuador could unlock new insights for conservation ecologists. A new collaboration between biologists and computer scientists at DePaul seeks to sequence … Read more
