Weight loss medication reduced both day and nighttime blood pressure levels, finds new study.

Researchers have found that the molecule RvT4 enhances the body's natural defenses against atherosclerosis (hardening of the arteries) in patients with rheumatoid arthritis.

A new computer program allows scientists to design synthetic DNA segments that indicate, in real time, the state of cells. It will be used to screen for anti-cancer or viral infections drugs, or to improve gene and cell-based immunotherapies.

New study reveals how gene expression shapes the diverse smelling and tasting abilities of different fly species. Most genes are surprisingly stable, but thousands have evolved to create unique olfactory landscapes. Sex differences in sensing are widespread and involve specific cell types in key tissues. The study provides insights into the evolution of sensory systems in general, with potential implications for understanding human olfaction.

Virus family history could help scientists identify which strains have potential to become the so-called Disease X that causes the next global pandemic.

Switching to ammonia as a marine fuel, with the goal of decarbonization, can instead create entirely new problems. This is shown in a study where researchers carried out life cycle analyses for batteries and for three electrofuels including ammonia. Eutrophication and acidification are some of the environmental problems that can be traced to the use of ammonia -- as well as emissions of laughing gas, which is a very potent greenhouse gas.

The processing of visual information begins with a targeted and balanced communication between nerve cells in the retina via synapses. Proteins in the vicinity of nerve cells play an important role in the development, maturation, and function of these synapses. A research team was able to show that the combined loss of four proteins leads to a severe impairment of the function of the retina, reduced visual movement processing and significant synaptic changes.

Scientists have found a way to boost ethanol production via yeast fermentation, a standard method for converting plant sugars into biofuels. Their approach relies on careful timing and a tight division of labor among synthetic yeast strains to yield more ethanol per unit of plant sugars than previous approaches have achieved.

Researchers wrote new computer algorithms to redesign the interiors of padding down to the scale of a millimeter or less. The result: New kinds of cushions that can absorb as much as 25% more force than current state-of-the-art technologies.

Experts have discovered how to create different colors of blue cheese. After discovering how the classic blue-green veining is created, a team of experts were able to create a variety of different fungal strains that could be used to make cheese with colors ranging from white to yellow-green to red-brown-pink and light and dark blues.

New research sheds light on tiny plankton, which measure less than 0.02mm in diameter but can make up more than 70% of the plankton biomass found in the ocean.

The Circumpolar Current works as a regulator of the planet's climate. Its origins were thought to have caused the formation of the permanent ice in Antarctica about 34 million years ago. Now, a study has cast doubt on this theory, and has changed the understanding of how the ice sheet in Antarctic developed in the past, and what this could mean in the future as the planet's climate changes.

Scientists have found soundwaves from low-intensity focused ultrasound aimed at a place deep in the brain called the insula can reduce both the perception of pain and other effects of pain, such as heart rate changes.

The proverb "necessity is the mother of invention" has been used to describe the source from which our cultural evolution springs. After all, need in times of scarcity has forced humans to continually invent new technologies that have driven the remarkable cumulative culture of our species. But an invention only becomes cultural if it is learned and spread by many individuals. In other words, the invention must be socially transmitted. But what are the forces that drive social transmission?

The algae P. antarctica has two forms of the enzyme that makes the amino acid methionine, one needing B12, and one that is slower, but doesn't need it. This means it has the ability to adapt and survive with low B12 availability. The presence of the MetE gene in P. antarctica gives the algae the ability to adapt to lower vitamin B12 availability, giving it a potential advantage to bloom in the early austral spring when bacterial production is low. P. antarctica takes in the CO2 and releases oxygen through photosynthesis. Understanding its ability to grow in environments with low vitamin B12 availability can help climate modelers make more accurate predictions.

Researchers have developed a first-of-its-kind, handheld electrochemical sensor that can accurately detect fentanyl in urine within seconds. The proof-of-concept technology can detect even trace amounts of fentanyl with 98% accuracy using a small portable device without costly and time-consuming lab analysis.

Engineers have developed an ultra-sensitive sensor made with graphene that can detect extraordinarily low concentrations of lead ions in water. The device achieves a record limit of detection of lead down to the femtomolar range, which is one million times more sensitive than previous technologies.

The world's largest brain study of childhood trauma has revealed how it affects development and rewires vital pathways. The study uncovered a disruption in neural networks involved in self-focus and problem-solving. This means under-18s who experienced abuse may struggle with emotions, empathy and understanding their bodies.

An economical process with green hydrogen can be used to extract CO2-free iron from the red mud generated in aluminum production.

Scientists have used a combination of scanning transmission electron microscopy (STEM) and computational modeling to get a closer look and deeper understanding of tantalum oxide. When this amorphous oxide layer forms on the surface of tantalum -- a superconductor that shows great promise for making the 'qubit' building blocks of a quantum computer -- it can impede the material's ability to retain quantum information. Learning how the oxide forms may offer clues as to why this happens -- and potentially point to ways to prevent quantum coherence loss.
