Key protein protects blood stem cells from premature aging

November 12, 2020

Haematopoietic stem cells (HSCs) produce other blood and immune cells, and ramp up production when an infection strikes – scientists from the UK have now identified how the HSCs protect themselves during the arduous task. A protein, YTHDF2 for short, regulates genes that control inflammatory processes that follow infection, protecting the stem cells from damage […]

High-resolution images, simulations of the inner ear offer insights into hearing loss

October 5, 2020

Using X-ray crystallography, a group of scientists at Ohio State University (OSU), US, have managed to produce atomic-level maps of very fine filaments inside our ears that help with sound and balance. The tiny filaments are attached to the top of microscopic hairs that in turn sit on top of hair cells inside the inner […]

Protein-based biomarker in eye fluid can single out Alzheimer’s disease

September 24, 2020

“One of the biggest priorities in Alzheimer’s disease research is to develop ways to diagnose the disease before the onset of symptoms, so as to allow for early treatment,” said Manju Subramanian from the Department of Ophthalmology at Boston Medical Center (BMC), US. Subramanian is one of a few scientists who have recently discovered a […]

‘Drawn-on-skin’ electronics can better track sensitive data in moving subjects

August 3, 2020

Wearable bioelectronics monitors physiological information as a means to prevent and treat illness and injury. But even the most flexible wearables are unable to move precisely with the skin. A team of engineering researchers at the University of Houston, US, have developed new, drawn-on-skin electronics that seamlessly collect biological data, regardless of the wearer’s movements. […]

Researchers report lower risk of dying among critically-ill COVID-19 patients after drug

July 21, 2020

Researchers from the University of Michigan (U-M), US, have noticed that critically-ill COVID-19 patients who received an intravenous drugwere 45% less likely to die and would more likely be out of the hospital or off a ventilator in about one month after treatment.While there was a lower risk of death in patients who received intravenous […]

Flexible electronic sensor patch tracks vitamin C and other nutrients via sweat

May 28, 2020

To gauge a person’s vitamin C levels – vitamin C supports the immune system and notably helps with wound healing – scientists from the University of California-San Diego (UCSD), US, have developed a thin, flexible, stretchable skin patch which generates an electric current in accordance with the user’s sweat. The strength of the electric current […]

Researchers think novel coronavirus will spread “no matter the climate conditions”

May 25, 2020

Researchers from the Princeton University Environmental Institute (PEI) in New Jersey, US, believe the first wave of the COVID-19 pandemic is not greatly affected by local variations in climate. The rapid spread of the virus in tropical nations, such as Brazil and Australia, and others in the Southern Hemisphere further indicates that warmer conditions will […]

Smartphone snap of the eyelid can detect signs of anaemia

May 25, 2020

Diagnoses of blood disorders usually eat up time, but new software has been developed to ease the process – using a smartphone camera, the software assesses levels of haemoglobin in red blood cells to check for conditions like anaemia or kidney injuries. The team of scientists at Purdue University (Purdue), US, hopes to offer this […]

VITAL COVID-19 ventilator prototype developed in less than 40 days by NASA

April 27, 2020

The National Aeronautics and Space Administration (NASA) in US have come up with an easy-to-build, inexpensive high-pressure ventilator to help with the unexpected shortage due to the COVID-19 pandemic. The Ventilator Intervention Technology Accessible Locally (VITAL) prototype was developed in only 37 days at NASA’s Jet Propulsion Laboratory (JPL) in California, and recently passed a […]
