As temperatures rise, the bees change how they fly to decrease the heat they generate from metabolism, which helps the insects avoid overheating and save precious water.
Many neurodegenerative diseases, such as dementia, are characterized by the abnormal aggregation of proteins inside cells, and treatments are being developed to break them up. But new research suggests that for some diseases, the aggregates are not directly killing cells. Aggregates prevent a protein, SIFI, from switching off the cells' stress response, and the constant stress kills cells. This suggests a strategy to treat these diseases without needing to mop up protein aggregates.
Researchers are further improving CRISPR's versatility to engineer new grasses and yeasts for biochemical production.
Researchers have used equipment originally intended for astronomy observation to capture transformations in the nuclear structure of atomic nuclei, reports a new study.
Australian birds that live on islands are among the species most at risk of extinction, a first-of-its-kind study has shown. Australia has over 750 native bird species. But many of them are facing an uncertain future.
Scientists develop novel underwater bio-adhesive patches with mussel adhesive protein.
Desert ants find their way during an early learning phase with the help of the Earth's magnetic field. The associated learning process leaves clear traces in their nervous system.
Since the turn of the century, six new chemical elements have been discovered and subsequently added to the periodic table of elements, the very icon of chemistry. These new elements have high atomic numbers up to 118 and are significantly heavier than uranium, the element with the highest atomic number (92) found in larger quantities on Earth. This raises questions such as how many more of these superheavy species are waiting to be discovered, where -- if at all -- is a fundamental limit in the creation of these elements, and what are the characteristics of the so-called island of enhanced stability. In a recent review, experts in theoretical and experimental chemistry and physics of the heaviest elements and their nuclei summarize the major challenges and offer a fresh view on new superheavy elements and the limit of the periodic table.
An estimated 11,000 sq miles or 28,707 sq kilometers of Greenland's ice sheet and glaciers have melted over the last three decades, according to a major analysis of historic satellite records.
A specific combination of targeted therapy and immunotherapy may better help patients with non-small cell lung cancer (NSCLC) overcome inherent immune resistance and reinvigorate anti-tumor activity, according to a new study.
A new study by researchers has revealed a sustainable method of efficiently converting waste heat into electricity using Irish wood products, while minimizing costs and environmental impact.
People using anabolic steroids could be increasing their underlying risk of a heart condition called atrial fibrillation, according to a new study.
Oxytocin, a naturally occurring chemical in the brain, plays a crucial role in various cognitive functions, including memory. A recent study revealed that the activation of neurons in the supramammillary nucleus of the mouse brain enhances performance in object recognition tasks. This discovery implies that specific oxytocin neurons play a pivotal role in modulating object recognition memory in mice.
The properties of supramolecular polymers are dictated by the self-assembled state of the molecules. However, not much is known about the impact of morphologies on the properties of nano- and mesoscopic-scale polymeric assemblies. Recently, a research team demonstrated how terminus-free toroids and random coils derived from the same luminescent molecule show different photophysical properties. The team also presented a novel method for purifying the toroidal structure.
Chiral skyrmions are a special type of spin textures in magnetic materials with asymmetric exchange interactions. They can be treated as quasi-particles and carry integer topological charges. Scientists have recently studied the random walk-behaviors of chiral skyrmions by simulating their dynamics within a ferromagnetic layer surrounded by chiral flower-like obstacles. The simulations reveal that the system behaves like a topological sorting device, indicating its use in information processing and computing devices.
Researchers have created a new version of a microbe to compete economically with E. coli -- a bacteria commonly used as a research tool due to its ability to synthesize proteins -- to conduct low-cost and scalable synthetic biological experiments.
A new study examines the circumstances behind who is found at fault when cars hit pedestrians in an urban area. Results showed that the environment where the crash took place -- especially the types of roads and the amount of access to marked crosswalks -- played a key role in whether the pedestrian or the driver was blamed for the collision.
For the first time, researchers have investigated how ropes and fishing lines are handled by the Norwegian commercial fishing industry. The fishing fleet loses almost 400 tons of rope in Norwegian waters every year.
A new clinical trial suggests that a combination of the drug vorinostat and immunotherapy can coax HIV-infected cells out of latency and attack them. The findings highlight how close -- yet still far -- researchers have come to developing a cure for HIV-1.
Researchers have shed new light on how viral evolution, population immunity, and the co-circulation of other flu viruses shape seasonal flu epidemics.
