Phosphates are essential substances that occur naturally in the human body and make up a considerable portion of our nutrition. They occur in almost all foods, especially those high in protein, such as cheese, cold cuts and meat. A certain group of phosphates is authorised as food additives in the European Union.
The herb kratom is increasingly being used to manage pain and treat opioid addiction, but it's not safe to use as an herbal supplement, according to new research led by faculty at Binghamton University, State University of New York.
The movie Finding Nemo could have a much darker sequel -- as artificial light in coral reefs leaves the famous fish unable to reproduce offspring, according to a new study. Results from a new study published in Biology Letters show an increasing amount of artificial light at night (ALAN) in coral reefs, even at relatively low levels, masks natural cues which trigger clownfish eggs to hatch after dusk.
Ping! The popular 1990 film, The Hunt for Red October, helped introduce sonar technology on submarines to pop culture. Now, nearly 30 years later, a team of scientists at the University of Missouri is using this same sonar technology as inspiration to develop a rapid, inexpensive way to determine whether the drinking water is safe to consume. Based on their results, the scientists said they can determine changes in the physical properties of liquids.
Your advance look at two new studies publishing online on July 8, 2019 in the American Journal of Tropical Medicine and Hygiene.
Scientists at the Center for Research on Inflammatory Diseases (CRID) show why pediatric patients with sepsis suffer from more inflammation and organ injury than adults. New treatment strategies may be tested.
Agitoxin-2 (AgTx2) from scorpion venom is a potent blocker of K+ channels. Here, we observed the binding dynamics of AgTx2 to the KcsA channel using high-speed atomic force microscopy. From the images obtained, single-molecule kinetic analyses revealed that the affinity of the channel for AgTx2 increased during persistent binding and decreased during persistent dissociation. We propose a four-state model with relevant rate constants. An induced-fit pathway was dominant and accelerated binding by 400 times.
An article published today in the Open Access journal GigaScience might make you squirm if you plan to hit the beach. This article presents the draft genomes of three jellyfish species, which have a range of physical traits and level of toxicity. Jellyfish kill more people than sharks, stingrays, and sea snakes combined; thus, having sequences and their analyses available provides an essential resource for future investigation of toxin gene evolution and body shape differences.
Thirdhand smoke can damage epithelial cells in the respiratory system by stressing cells and causing them to fight for survival, a research team led by scientists at the University of California, Riverside, has found. The finding could assist physicians treating patients exposed to thirdhand smoke.
Researchers at the universities in Stockholm and Lund, in collaboration with researchers from the University of California, have found a new toxin that selectively targets mosquitos. This can lead to innovative and environmentally friendly approaches to reduce malaria. The results are presented in an article published in Nature Communications.
