Researchers at the University of Tsukuba in Japan show that low metabolic flexibility is associated with reduced fat metabolism during sleep.

Researchers from University of Tsukuba in collaboration with Yamagata University scientists find that exposure to light with less blue before sleep is better for energy metabolism. Extended exposure to light during nighttime can have negative consequences for human health. But now, researchers from Japan have identified a new type of light with reduced consequences for physiological changes during sleep.

Recreating major pathological features of Parkinson’s disease in a lab-grown, human mini-brain will help researchers to explore new treatments. This is the first time that Lewy bodies, a hallmark of Parkinson’s disease in patients’ brains, have been produced in the laboratory, offering new insights into the disease.

KAIST researchers have used whole-genome sequencing to track the development from a single fertilized-egg to a human body.

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

Through a follow-up analysis of d-ROM values taken pre- and post-cardiopulmonary exercise tests, researchers have found that heart failure patients with increased oxidative stress during exercise have a poorer prognosis - leading to potential design of exercise routines around individual patients.

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.

ARN's August 2021 newsletter features research about cancer-killing nanoparticles, a more powerful radio receiver tuning into space, good tiger news, and more. We also check in with a research team to find out what it was like to be the center of media attention.

An injection made of a hydrogel containing stem cells could treat damaged tissue following a heart attack.

Testing a large library of compounds reveals an easy-to-make lipid that can carry genetic code into the lung to treat disease.

Magnetic field could boost blood vessel growth to regenerate damaged tissue.

A subset of fibroblasts located in small foci of tissue on the edges of extensive scarring produce a protein that protects against cell aging.

Scientists have developed a rapid, highly accurate test to detect antibodies against the spike protein of SARS-CoV-2 in human serum, opening a new avenue for understanding the full extent of the pandemic and evaluating the effectiveness of vaccines.

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

Our brain has no lymphatic system; however, it does have fluid flow, which is believed to play a role in removing waste from the brain. However, the fluid's point of origin and fluid flow is still unclear. The “multi-scale stable isotopes imaging” project in Hokkaido University aims to solve this mystery using advanced technology. “We would not have been able to perform this study without Hokkaido University’s MRI technology and the isotope microscope,” said the project’s PI, Professor Kohsuke Kudo of the Department of Radiology, Faculty of Medicine.

The inaugural virtual edition of Singapore Health and Biomedical Congress will be held on 7 & 8 October 2021. Register and submit abstracts now.

A signalling protein thought to be able to treat liver damage in paracetamol toxicity could actually worsen it. Instead, Singapore scientists discovered, blocking its effects could be the way forward.

Cryo-electron microscopy and computer simulations uncover how a cellular protein helps transport omega-3 fatty acids to the brain and eye, with implications for drug development.

A team of scientists has shown that the healing of skin blisters is driven by hair follicle stem cells, which delay their own development in the process.

• Glioblastoma (GBM) is a highly aggressive type of brain cancer. Even with current standard of care, 50% of patients die within 15 months of diagnosis. • This complex cancer is difficult to treat due to its location, structure, ability to spread quickly, high recurrence rate and severely limited treatment options. • GBM tumours can look identical under the microscope but respond differently to the same treatment. • With a national grant of about S$10 million, researchers in Singapore are working with overseas collaborators to address these challenges and develop new diagnostic and treatment options so patients can receive effective targeted therapy.

Researchers at The International Islamic University Malaysia (IIUM) have developed an algorithmic approach to predict progression of a condition called pterygium, which involves abnormal tissue growth across the eye.

Researchers have observed DNA spooling and unspooling in real time using CRISPR to attach fluorescent tags to very specific DNA points in living cells.

A simple tool allows researchers to track how different subpopulations of the Plasmodium knowlesi parasite are changing over time.

A spray-on magnetic coat turns any object into a robot controlled by a magnetic field. The biocompatible robots can walk, crawl and roll, and switch motions on demand.

A spinning toy meets hydrodynamics and sets point-of-care diagnostics in motion.

The trick to extremely thin supercapacitors with improved performance is spraying graphene ink at an angle.

First-of-its-kind in Singapore, the clinical trial will test a technology that enables specific cell therapy products to be manufactured for use in patients.

A mitochondrial peptide called MOCCI has a surprising sidekick, and they work together to regulate inflammation and immunity, Singapore researchers reveal.

A five-year study in Singapore has highlighted that chronic wounds among patients with diabetic foot ulcers and bed sores led to longer hospital stays.

New national body established to further research insights, improve patient outcomes and create new economic opportunities for the biomedical technology industry.
