Artificial intelligence outperforms clinical tests at predicting progress of Alzheimer's disease

Scientists have developed an artificially-intelligent tool capable of predicting in four cases out of five whether people with early signs of dementia will remain stable or develop Alzheimer's disease. The team say this new approach could reduce the need for invasive and costly diagnostic tests while improving treatment outcomes early when interventions such as lifestyle changes or new medicines may have a chance to work best.

Microbeads with adaptable fluorescent colors from visible light to near-infrared

Researchers have successfully developed an environmentally friendly, microspherical fluorescent material primarily made from citric acid. These microbeads emit various colors of light depending on the illuminating light and the size of the beads, which suggests a wide range of applications. Furthermore, the use of plant-derived materials allows for low-cost and energy-efficient synthesis.

A chemical claw machine bends and stretches when exposed to vapors

Scientists have developed a tiny 'claw machine' that is able to pick up and drop a marble-sized ball in response to exposure to chemical vapors. The findings point to a technique that can enable soft actuators--the parts of a machine that make it move--to perform multiple tasks without the need for additional costly materials. While existing soft actuators can be 'one-trick ponies' restricted to one type of movement, this novel composite film contorts itself in different ways depending on the vapor that it is exposed to.

Researchers uncover brain region's role in hearing and learning

The human brain is remarkably adept at adjusting what we hear based on contexts, like our current environment or priorities, but it's still unknown how exactly the brain helps us detect, filter and react to sounds. Now, biologists are a step closer to solving that mystery. Using an animal model, the researchers found that the orbitofrontal cortex (OFC), a brain region associated with decision-making but not typically linked to hearing, plays a central role in helping the auditory cortex (a primary hearing center of the brain) adapt to changing contexts or situations.

Uncovering late-onset combined immune deficiency in chromosome 18q deletion syndrome

Researchers have revealed a novel association between chromosome 18q deletion syndrome and late-onset combined immunodeficiency (LOCID). Their finding challenges the previously held notion that 18q deletion syndrome only involves humoral immunodeficiency affecting B cells and antibody production. Moreover, the study highlights the need for regular immune function testing in 18q deletion syndrome patients for early diagnosis and improved management.

Hydrogen flight looks ready for take-off with new advances

The possibility of hydrogen-powered flight means greater opportunities for fossil-free travel, and the technological advances to make this happen are moving fast. New studies show that almost all air travel within a 750-mile radius (1200 km) could be made with hydrogen-powered aircraft by 2045, and with a novel heat exchanger currently in development, this range could be even further.

Dark matter in dwarf galaxy tracked using stellar motions

The qualities and behavior of dark matter, the invisible 'glue' of the universe, continue to be shrouded in mystery. Though galaxies are mostly made of dark matter, understanding how it is distributed within a galaxy offers clues to what this substance is, and how it's relevant to a galaxy's evolution.

A new species of extinct crocodile relative rewrites life on the Triassic coastline

The surprising discovery of a new species of extinct crocodile relative from the Triassic Favret Formation of Nevada, USA, rewrites the story of life along the coasts during the first act of the Age of Dinosaurs. The new species Benggwigwishingasuchus eremicarminis reveals that while giant ichthyosaurs ruled the oceans, the ancient crocodile kin known as pseudosuchian archosaurs ruled the shores across the Middle Triassic globe between 247.2 and 237 million years ago.

Building materials for water-rich planets in the early solar system

Age data for certain classes of meteorite have made it possible to gain new findings on the origin of small water-rich astronomical bodies in the early solar system. These planetesimals continually supplied building materials for planets -- also for the Earth, whose original material contained little water. The Earth received its actual water through planetesimals, which emerged at low temperatures in the outer solar system, as shown by computational models carried out by an international research teach with participation by earth scientists.
