Life depends on genes being switched on and off at exactly the right time. Even the simplest living organisms do this, but usually over short distances across the DNA sequence, with the on/off switch typically right next to a gene. This basic form of genomic regulation is probably as old as life on Earth. A new study finds that the ability to control genes from far away, over many tens... Read more ›

Our brain is a complex organ. Billions of nerve cells are wired in an intricate network, constantly processing signals, enabling us to recall memories or to move our bodies. Making sense of this complicated network requires a precise look into how these nerve cells are arranged and connected. A new method makes use of off-the-shelf light microscopes, hydrogel and deep learning. Read more ›

A research team has adapted an intervention for childhood obesity prevention to better serve Latina mothers, non-maternal caregivers, and families of low-income backgrounds in Inland Southern California. The study could make significant contributions to public health by ensuring that early childhood obesity prevention strategies begin in infancy with infant feeding and are culturally and linguistically relevant for immigrant communities.

Brain researchers have identified a bridge between the thalamus and the cortex as the key area that is modified during motor learning functions. They found that such learning does much more than adjust activity levels, it sculpts the circuit's wiring, refining the conversation between brain regions. Read more ›

A new class of molecules capable of killing the cancer cells that are refractory to standard treatments and responsible for recurrence has just been developed. This crucial advance in the fight against metastatic cancer is based on identifying the cellular site for ferroptosis initiation, a natural process, catalyzed by iron, that sparks the oxidative degradation of cell membranes.

Scientists have mapped the 3-D structure of the human sweet taste receptor, the molecular machine that allows us to taste sweet things. This could lead to the discovery of new regulators of the receptor that would significantly alter our attraction to and appetite for sugar. Read more ›

Scientists have developed a vacuum-assisted extrusion method that reduces internal porosity -- by up to 75% -- in large-scale 3D-printed polymer parts. Large-scale additive manufacturing has been hindered by internal porosity that weaken printed components. Reducing porosity is key to improving overall performance. Researchers tackled this challenge with a novel approach: integrating a vacuum hopper during the extrusion process to remove trapped gases and minimize void formation in fiber-reinforced material Read more ›

Bacterial resistance negates the effect of antibiotics in the treatment of infection. Using mouse models, researchers now show that if antibiotics are administered with an enzyme called endolysin, the combined effect protects against infection by resistant bacteria in all bodily organs -- including the brain, which antibiotics alone have difficulty reaching.

Lichen is an understated presence in our everyday world, often found clinging to trees and rocks. Its true beauty lies in its unique symbiotic system of fungi and algae, or cyanobacteria, that form a self-sustaining partnership, allowing it to thrive in even the harshest conditions. With that inspiration, researchers created a synthetic lichen system that collaborates like natural lichens. Their system uses cyanobacteria, which turns air and sunlight into food,... Read more ›

Eating a healthy diet as a child is linked to girls having their first menstrual period at an older age than those who consumed a less healthy diet, according to a new study. The findings remained unaltered by the girls' body mass index or height, both of which have been associated with the earlier onset of periods. The study has implications for health in later life as it is well... Read more ›

For social animals, communication is a key that unlocks the benefits of group living. It's well known that animals with more complex social lives tend to have more intricate ways of communicating, from the clicks and whistles of dolphins to the calls of primates. While this pattern is found broadly in many species, a new study on wild parrots drills deep into the social and vocal lives of individual birds.... Read more ›

Termites -- infamous for their ability to destroy wood -- are rarely welcomed into rainforests that have been painstakingly replanted. But a new paper suggests that termite transplants may be necessary to help regenerating forests to thrive. Scientists found that termites are not thriving in replanted rainforests in Australia. Because decomposers like termites are essential for recycling nutrients and carbon, the researchers worry that the insect's slow recovery could hinder... Read more ›

Electronic devices rely on materials whose electrical properties change with temperature, making them less stable in extreme conditions. A discovery that challenges conventional wisdom in physics suggests that bismuth, a metal, could serve as the foundation for highly stable electronic components. The researchers observed a mysterious electrical effect in ultra-thin bismuth that remains unchanged across a wide temperature range, from near absolute zero (-273 C) to room temperature. Read more ›

A team of researchers has developed a cost-effective, high-throughput technology for detecting nanoplastics and microplastics in the environment. These particles are pervasive, posing health and environmental risks, yet detecting them at the nanoscale has been difficult. The 3D-printed HoLDI-MS test platform overcomes the limitations of traditional mass spectrometry by enabling direct analysis of samples without requiring complex sample preparation. The researchers say it also will work for detection of wat Read more ›

Biologists have discovered two previously unknown species of crocodiles, one living on the island of Cozumel and the other on the atoll of Banco Chinchorro, both off the Yucat n Peninsula. The findings challenge long-held assumptions about the American crocodile (Crocodylus acutus) and highlight the urgent need for conservation efforts, the researchers say. Read more ›

A new study is reshaping how scientists date dinosaur fossils in Alberta's Dinosaur Provincial Park (DPP). Using advanced drone-assisted 3D mapping, researchers have uncovered significant variations in a key geological marker, challenging long-standing methods of determining the ages of dinosaur fossils.
