Low concentrations of cetylpyridinium chloride, an antimicrobial agent present in mouthwashes, inhibit the infectivity of four variants of SARS-CoV-2.

Metastasis—when cancer spreads to form new tumors—causes approximately 90% of cancer-related deaths. Because metastatic cancer cells circulate in the blood, the liver—which filters the blood—is considered the most vulnerable organ, so treatments that prevent liver metastasis are urgently needed. A team of Osaka Metropolitan University researchers discovered a mechanism that allows metastatic cancer cells to infiltrate the liver, and how that infiltration can be blocked by inhibiting a related protein.

A simple and economical method of detecting SARS-CoV-2 viral loads in wastewater with high sensitivity has been developed, expanding the use of wastewater-based epidemiology for tracking the virus in populations.

Giants in History: Joo-myung Seok (November 13, 1908 – October 6, 1950) was a Korean butterfly entomologist who made important contributions to the taxonomy of the native butterfly species in Korea.

Scientists have pinpointed a protein in lysosomes that is involved in recycling a crucial fatty component of cell membranes to keep cells healthy.

- A research team led by Professor Lee Sungwon from DGIST succeeded in developing the world’s first mesh (nanomesh) structured electronic skin device (organic field-effect transistor) - An electronic skin device comprising only a mesh (nanomesh) structure that can measure and process bio-signals for a prolonged period indicates a big step toward integrated systems for electronic skin devices.

Taxidermy is the art of creating lifelike representations of animals by using their skin, feathers, scales or fur. It draws on the skills of painting, sculpture, model-making and deep knowledge of animal anatomy. Used for creating trophies of hunted animals as symbols of heroism, the practice was also utilised for pedagogical purposes in institutions like museums.

Chaos theory improves understanding of Arctic narwhal behavior, with the aim of helping efforts to protect this vulnerable species.

Researchers led by Osaka University developed a novel fluorescent sensor to detect and monitor levels of the neuropeptide oxytocin, also known as the “happy hormone.” The OT sensor facilitated the successful measurement of OT dynamics in the brains of living animals and may serve as a foundation for the development of therapeutics for the treatment of neurological disorders such as autism and schizophrenia.

A pathway that malfunctions in advanced non-alcoholic fatty liver disease could be fixed with the aid of spermidine, a compound naturally found in bodily cells and certain whole foods.

Scientists have uncovered how Coxsackievirus B3, the most common cause for viral heart inflammation, takes advantage of a specific heart sensor to trigger chronic inflammation that can lead to heart failure.

A research group led by the Institute of Industrial Science, The University of Tokyo, finds that sensory neurons in human skin modulate melanocytes via the secretion of Repulsive Guidance Molecule B

Cellular structures called mitochondria depend on microproteins to assist and control the assembly of a protein chain that extracts energy from nutrients, according to a new study by scientists in Singapore.

The Memorandum of Understanding signed between The Ngee Ann Kongsi and Duke-NUS Medical School emphasises the need for more research as treatment and prevention options are currently limited for conditions such as Parkinson’s disease.

Research shows that natural catastrophes may trigger or exacerbate attacks of incapacitating migraine in disaster victims.

Microglia acts as the first line of defense in the central nervous system, constantly scanning for pathogens and abnormalities. Now, Tohoku University scientists have demonstrated that microglial genes associated with the synapse—structures that allow neurons to pass signals to one another—undergo changes in response to the brain processing traumatic memories.

Researchers at The University of Tokyo create a geometric representation of thermodynamic systems and apply it to self-replicating processes, which may help improve our understanding of the physical constraints of living organisms

Researchers study sex-determination in birds using primordial germ cells and RNA-sequencing analysis.

Researchers at Hiroshima University are closer to identifying the molecular processes underlying how floods deprive plants of oxygen — and how to engineer hardier crops.

Giants in History: Hwang Hye-seong (5 July 1920 – 14 December 2006) was an expert on Korean royal court cuisine, the knowledge of which she dedicated her career to keeping alive.

Lim Boo Liat (21 August 1926 – 11 July 2020), a leading authority in the conservation of Malaysia’s biological diversity, had his initial interest in the outdoors piqued by nature lessons in school.

Scientists understand genes related to intellectual disabilities, but are often unsure of how mutations in these genes cause developmental disorders. Now, a research group led by two Tohoku University researchers has uncovered the role of CHAMP1—a gene whose mutations are associated with intellectual disability—in neuronal development.

Osaka Metropolitan University researchers have clarified that an adenosine analog—the antibiotic toyocamycin—is taken up into cells by a concentrative nucleoside transporter (CNT) in Candida albicans, an opportunistic yeast fungus that causes candidiasis infections. This was also true of the human CNT3 protein. They found that C. albicans CNT and human CNT3 proteins take up similar molecules at different rates depending on their molecular size and structure. These results are expected to lead to the development of new antifungal drugs that are effective only against C. albicans and safe for humans.

Two new approaches could help scientists use existing sequencing technology to better-distinguish RNA changes that affect how their genetic code is read.

A baby’s cry is a form of communication used to attract attention from adult caregivers, and every baby cries in a similar but distinct way. An international research team has studied the vocal behavior of baby mice, called pups, to determine how the age of the father affects the pups’ vocal communication and body weight development. Their study will help them better understand vocal development in human babies.

Scientists show that there is a close association between clinical cases of COVID-19 and viral loads in wastewater, with the viral loads picking up to two days before the cases were detected.

Two novel hypotheses have been proposed that address the “two-fold cost of sex”: one of the biggest enigmas in the evolution of sexual reproduction.

Human brains learn patterns over time and we don’t even realize it. New insight into how this works could improve learning and other cognitive processes.
