Chloride ions evoke taste sensation by binding to sweet taste receptors

Humans perceive five basic taste sensations: sweet, umami, bitter, salty, and sour. Specific foods trigger taste recognition of these sensations through the activation of different receptors in our taste buds.

Brain scans link signs of cellular aging to symptoms of Alzheimer’s

According to a new study led by Anya Topiwala of Oxford Population Health, a division of the University of Oxford in the United Kingdom, and published on March 22nd, 2023 in the open-access journal PLOS ONE, changes in the brain caused by Alzheimer’s disease are connected to telomeres shortening, the protective caps on the ends of chromosomes that shorten as cells age.

Pesticide residues in water test kit for sustainable and safe agriculture

Farmers in Thailand still largely use chemical herbicides, especially paraquat and atrazine, to control weeds on their farms. According to research by the Office of Agricultural Economics, in 2019, Thailand imported almost 10 million kilograms of paraquat and close to 3.5 million kilograms of atrazine.

Highly sensitive bioluminescent platform for nucleic acid detection

Despite significant advances, numerous highly sensitive viral disease diagnostic tests even now require complex techniques to prepare a sample or decipher a result, making them inconvenient for point-of-care settings or areas with limited resources.

Study reveals the cellular composition and circuit organization of the locus coeruleus

A small nucleus in the brainstem called locus coeruleus (literally the "blue spot,") is the primary source of a major neuromodulator, norepinephrine (NE), an important mediator of the 'fight or flight' response in animals. However, very little is known about the local connections of this small albeit critically important group of neurons.

Novel newborn screening test for HCU works by measuring homocysteine levels

Scientists have developed a test that could greatly improve quality of life for infants with homocystinuria (HCU)-;a congenital disease that, if not treated early, causes serious complications. Research demonstrating the efficacy of this test was published today in AACC's Clinical Chemistry journal.

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.

Experts unravel a vast network that shows how cells adjust in real-time to withstand stresses

Every minute of every day, our body adapts to meet the needs of each moment. When we binge on carbs, exercise, or become sick, chemical reactions inside our cells switch on, slow down, or shift strategy so that we have the energy and strength we need.
