A research team led by the National Institute for Physiological Sciences and joined by Hokkaido University explored the role of pain neurons in the regulation of endotoxic death. They found that peptide named Reg3γ acts as a pain neuron-enriched brain-targeted hormone that protects the host from endotoxic death.

Simulations have led to the fabrication of a polymer-DNA gel that could be used in tissue regeneration and robotics.

Giants in History: Eminent Filipina scientist and educator Clara Lim-Sylianco (18 August 1925 – 23 July 2013) is remembered for her extensive research on mutagens – often-carcinogenic agents that permanently alter genetic materials such as DNA – antimutagens and bioorganic mechanisms.

Giants in History: In 1939, biochemist Kamala Sohonie (18 June 1911 – 28 June 1998) became the first woman to be accepted into the Indian Institute of Science (IISc).

Enzymatic hydrolysis of planteose: α-Galactosidase is a promising molecular target for root parasitic weed control

Scientists have identified a series of molecular candidates for those parts of dog allergens that cause immune reactions in people—the first step in developing a vaccine against most causes of dog allergies.

Julian Arca Banzon (13 March 1908 – 13 September 1988) was a biochemist from the Philippines who was a pioneer in alternative fuel research.

The missing link isn’t a not-yet-discovered fossil, after all. It’s a tiny, self-replicating globule called a coacervate droplet, developed by two researchers in Japan to represent the evolution of chemistry into biology.

Using the lamprey, researchers from Japan analyzed the photosensory mechanism of the pineal organ, also called the pineal gland, in non-mammalian vertebrates and discovered a novel mechanism of pineal color discrimination (two-cell system) in which two types of photoreceptor cells, each containing two different opsins, are used to detect color. This discovery may provide insight into the evolution of color detection in other animals, including color vision in humans.

iCeMS scientists and colleagues have designed a molecular code that powers up cancer-fighting immune cells.

A multi-functional, small molecule can tag mutant genetic sequences inside mitochondria for removal.

Cells translate their genetic material at rapid rates with exquisite precision to reproduce, repair damage or even combat disease. But the process can deregulate and give rise to disease. Byproducts of errant processes can build up like gunk in the gears, especially around neurons, breaking down the repair mechanisms and causing further damage and even neurodegenerative disorders such as Alzheimer’s disease.

Researchers from Osaka City University show the benefits of mixing alginic acid with calcium phosphate cement (CPC), a common bone replacement material, with in vitro and in vivo studies. The biopolymer is shown to improve the setting time and compressive strength of CPC, as well as help it acquire porosity – which allows cells to enter the defected area and grow new bone.

Researchers have found a way to enhance radiation therapy using novel iodine nanoparticles.

Researchers at The University of Tokyo Institute of Industrial Science use artificial intelligence to predict the size of cells over time without the need for simplifying assumptions, which may lead to a new understanding of microbiology principles and improved drug manufacturing from recombinant bacteria

Researchers analyze bone marrow-derived and peripheral blood-derived fibrin clots showing that the former contains more growth factors. They then show that bone marrow-derived fibrin clots can be used for meniscus suturing, even in the inner-most avascular regions, and with a 2-year post-operative follow-up, they show bone marrow-derived fibrin clots support healing better than their peripheral blood counterparts.

Publication bias, or the tendency of researchers and journals to not publish uninteresting findings, plagues much of the natural sciences and especially biomedical research. Hiroshima University researchers have developed a meta-analytic technique exploiting publicly available transcriptome databases that avoids the problem—and in so doing, discovered four genes previously unknown to be associated with responding to low-oxygen stress.

High-resolution genome structural analyses combined with large-scale simulations show the arrangements of the genome’s spool-like structures affecting gene expression.

Upcoming Solar System exploration missions will search for extraterrestrial (ET) life, but ET life may not be like Earth life. A new mass spectrometry analysis technique may allow for process-based ways to find ET life that is compositionally alien.

Scientists have shown that the biological molecule PD-L1 is a potential target for the treatment of metastasized oral malignant melanoma in dogs.

Researchers from The University of Tokyo develop a novel device for the safe and effective transplantation of human induced pluripotent stem cell (iPSC)-derived pancreatic beta-cells in type I diabetes mellitus

A hydrogel, a type of soft matter, developed at Hokkaido University successfully reverted cancer cells back to cancer stem cells within 24 hours, in six different human cancer types. This could lead to the development of anti-cancer stem cell drugs and personalized medicines.

Researchers at Kanazawa University report in Communications Chemistry that a molecule known as pillar[6]arene can form a host–guest compound with a cancer-associated metabolite. The phenomenon can be used to efficiently detect the metabolite in crude biological samples, which is important for preventing and treating metabolic syndrome and associated pathologies.

Investigations of a cellular protein have uncovered a possible link with schizophrenia.

iCeMS scientists have revealed how a transporter protein twists and squeezes compounds out of cells, including chemotherapy drugs from some cancer cells.

Researchers at WPI-IIIS find that normal sleep in mice depends on bacteria that help make neurotransmitters such as serotonin in the gut. The article, “Gut microbiota depletion by chronic antibiotic treatment alters the sleep/wake architecture and sleep EEG power spectra in mice,” was published in Scientific Reports.

A transporter protein that regulates cell membrane cholesterol likely played an important role in vertebrate evolution, according to a review published by iCeMS researchers in the journal FEBS Letters.

Turning off gene-editing until it reaches cell cycle phases where more accurate repairs are likely to happen offers a promising fix to CRISPR-Cas9’s problem with unwanted genetic changes.
