First molecular images of olfaction sets the stage to create novel smells

Breaking a longstanding impasse in our understanding of olfaction, scientists at UC San Francisco (UCSF) have created the first molecular-level, 3D picture of how an odor molecule activates a human odorant receptor, a crucial step in deciphering the sense of smell.

Merging cryo-TEM and tomography methods to reveal 3D morphology of dendrites

Documenting the lithiation process in TEM can provide a deep understanding of the electrode degradation mechanism during battery cycling, which enhances material modification for improved performance. The research was guided by Prof. Dong Su (Institute of Physics, Chinese Academy of Sciences).

Study evaluates the risk posed by the fungus Bd to amphibians across the continent of Africa

Mass fungus infections that drive populations worldwide to near-collapse don't just occur in science fiction. Chytridiomycosis, the worst vertebrate disease in recorded history, has already wiped out hundreds of species of amphibians around the world. Due to a large part to this fungal disease, 41% of amphibians are currently threatened with extinction. Only species living in Africa seemed to have been relatively spared from the scourge of chytridiomycosis – at least so far.

Aston University receives funding for the development of a diagnostic tool for children with brain tumors

Birmingham based charity, Help Harry Help Others and Aston University researchers, are working together to develop a pioneering pre-surgical diagnostic tool, which could see the eventual outcome of children with brain tumors drastically improve.

Research reports distinct patterns of reward-seeking behavior between OCD and problem gambling

Shinsuke Suzuki at The University of Melbourne, Australia reports distinct patterns of reward-seeking behavior between obsessive compulsive disorder (OCD) and problem gambling, in a study publishing in the open access journal PLOS Biology on March 14th. OCD is associated with lower-than-normal learning rates when rewards are less than expected. On the other hand, people with problem gambling exhibit boosted and blunted learning from rewards higher and lower than expected, respectively.

Study reveals the detrimental effects of even a few extra pounds on young people

A Kaiser Permanente study of more than 800,000 young people between the ages of 3 and 17 showed that youth at the upper range of average weight had a 26% higher risk of developing hypertension than those closer to what is considered average weight. The study was published March 14, 2023, in JAMA Network Open.

Gene that regulates cadmium distribution between leaf and grain in rice

Due to its accumulation in crops, specifically rice, cadmium (Cd), a hazardous heavy metal contaminant of cultivated land, poses a threat to human health. Thus, it is vital to develop methods to prevent Cd from accumulating in rice grains.

Mesophotic coral reefs function differently than their shallower counterparts, study shows

In a paper published today in Current Biology, researchers from the California Academy of Sciences Hope for Reefs initiative, along with Brazilian collaborators from the University of São Paulo, Federal University of Espírito Santo, and the Instituto Nacional da Mata Atlântica, show that mesophotic coral reefs function much differently than their shallower counterparts and are unlikely to offer a refuge for shallow water fishes trying to escape climate-change driven warming on the ocean's surface.

High correlation between the product of a gene in the majority of cancers

The product of a gene expressed in most cancers, including the most prevalent type of head and neck cancer, has been linked to elevated levels of white blood cells that produce antibodies inside tumors, according to researchers at the University of California San Diego School of Medicine and UC San Diego Moores Cancer Center.

Rice biologists embark on a three-year project to create genetically encoded antibiotics

Synthetic biologists at Rice University are embarking on a three-year project to create "genetically encoded antibiotics," strands of RNA that bacteria will readily copy and share that will selectively kill only disease-causing, pathogenic bacteria.

Novel method quantifies the total polysulfide content in fresh vegetables

Sulfur-rich foods, like onions and garlic, have long been recognized to have health-promoting properties. It has been difficult to investigate how food containing sulfur compounds enhances health because the levels—and types—of reactive polysulfides found in various vegetables have not been adequately assessed.
