Climate changes usually happens over long periods of time, but during the last glacial period, extreme fluctuations in temperature occurred within just a few years. Researchers have now been able to prove the phenomenon also occurred during the penultimate glacial period. Read more ›

Children's interest in, and competence perceptions of, mathematics are generally quite positive as they begin school, but turn less positive during the first three years. This is shown by a recent study exploring the development of children's motivation for mathematics during the early school years, and how that development is associated with their mathematics competence. The researchers followed nearly three hundred children for three years. Read more ›

In many cancers, such as ovarian cancer, each round of chemotherapy kills the majority of cancer cells, while a small population of them survives through treatment. These cells are typically more resistant for the next cycle of therapy and can thus regrow to a deadly, treatment resistant tumor. Researchers wanted to know how this small population of surviving cells differs from the other more sensitive cells already before the treatment.... Read more ›

Growing cartilage tissue in the lab could help patiens with injuries, but it is very hard to make the tissue grow in exactly the right shape. A new approach could solve this problem: Tiny spherical containers are created with a high-resolution 3D printer. These containers are then filled with cells and assembled into the desired shape. The cells from different containers connect, the container itself is degradable and eventually disappears. Read more ›

A new study has found the immune system in the blood of Alzheimer's patients is epigenetically altered. That means the patients' behavior or environment has caused changes that affect the way their genes work. Many of these altered immune genes are the same ones that increase an individual's risk for Alzheimer's. Scientists now theorize the cause could be a previous viral infection, environmental pollutants or other lifestyle factors and behaviors. Read more ›

Snail shells are often colorful and strikingly patterned. This is due to pigments that are produced in special cells of the snail and stored in the shell in varying concentrations. Fossil shells, on the other hand, are usually pale and inconspicuous because the pigments are very sensitive and have already decomposed. Residues of ancient color patterns are therefore very rare. This makes a new discovery all the more astonishing: researchers... Read more ›

Researchers have developed a sensor made from 'frozen smoke' that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far beyond the sensitivity of most indoor air quality sensors. Read more ›

Semiconductors are ubiquitous in modern technology, working to either enable or prevent the flow of electricity. In order to understand the potential of two-dimensional semiconductors for future computer and photovoltaic technologies, researchers investigated the bond that builds between the electrons and holes contained in these materials. By using a special method to break up the bond between electrons and holes, they were able to gain a microscopic insight into charge... Read more ›

A coating that can hide objects in plain sight, or an implant that behaves exactly like bone tissue: These extraordinary objects are already made from 'metamaterials'. Researchers have now developed an AI tool that not only can discover such extraordinary materials but also makes them fabrication-ready and durable. This makes it possible to create devices with unprecedented functionalities. Read more ›

Hydrogen stored in hydrogen boride sheets can be efficiently released electrochemically, report scientists. Through a series of experiments, they demonstrated that dispersing these sheets in an organic solvent and applying a small voltage is enough to release all the stored hydrogen efficiently. These findings suggest hydrogen boride sheets could soon become a safe and convenient way to store and transport hydrogen, which is a cleaner and more sustainable fuel. Read more ›

Researchers have captured time-lapse videos of stem cells dividing in growing plant roots. By watching how the cells divide in response to certain chemical signals over time, the team is uncovering new clues to how stem cells choose one developmental path over another. Read more ›

A team of scientists has devised means for classical computing to mimic a quantum computing with far fewer resources than previously thought. The scientists' results show that classical computing can be reconfigured to perform faster and more accurate calculations than state-of-the-art quantum computers. Read more ›
