New technology platform digitally counts growth factors in single cells

Whether healthy or diseased, human cells exhibit behaviors and processes that are largely dictated by growth factor molecules, which bind to receptors on the cells. For example, growth factors tell the cells to divide, move, and when to die--a process known as apoptosis.

The gene-edited twins born in China may have altered cognition and memory

A new study has fuelled further concerns over the controversial gene-editing experiment that was performed in China last year.

Study finds out similarity in function between healthy retina cell and tumor cell

How is a healthy retina cell like a tumor cell? It hijacks an energy-producing chemical reaction to churn out molecular building blocks. When tumor cells do it, they use the building blocks to make cancer grow and spread. But when retina cells do it, they renew photoreceptor membranes that keep our vision sharp.

Studies explore physiological dangers that climate change will have on animal life

A new review of more than 140 studies explores the physiological dangers that climate change will likely have on animal life, including humans. The review is published in the journal Physiology.

Researchers uncover interspecies communication between gut bacteria and host

Bacteria in the gut do far more than help digest food in the stomachs of their hosts, they can also tell the genes in their mammalian hosts what to do.

Frog-skin bacteria more diverse in cold and variable temperature regions, finds study

Amphibians are victims of lethal skin-disease epidemics. In the first global-scale study, researchers from 31 universities and research centers, including the Smithsonian Tropical Research Institute (STRI), collected skin bacteria from more than 2,300 healthy frogs and salamanders from 12 countries to describe microbes on a wide range of host animals to improve knowledge of the distribution of frog-skin bacteria, known to be important in maintaining amphibian health.

Study offers new insights into mechanisms of changes in erythrocytes under stress

Various stress effects make an integral part of modern life, and their minimization is of particular relevance.

Mitochondrial proteotoxicity appears to be epicentre of molecular pathogenesis

Researchers at the University of Helsinki uncovered the mechanisms for a novel cellular stress response arising from the toxicity of newly synthesized proteins.

Researchers use radio-telemetry to track the habitats of bottlenose dolphins

Using telemetry units in hospitals to monitor patient health is standard practice. Now, a similar approach is proving to be invaluable for dolphins, too.

Newly designed molecule could benefit people with Friedrich's Ataxia

Skin cells taken from patients with a rare genetic disorder are up to ten times more sensitive to damage from ultraviolet A radiation in laboratory tests, than those from a healthy population, according to new research from the University of Bath.

Study doesn’t find enough evidence related to effects of noncaloric sweeteners on gut microbiota

The study, carried out by the UGR professor of Biochemistry and Molecular Biology Ángel Gil and his research team, has been published in the scientific journal 'Advances in Nutrition'

Dietary fiber helps to aggregate gut particles, study shows

Food, microbes, and medicine all clump together as they move through our gut. Sticky molecules secreted into our intestines bind the gut particles in the same way that flour holds a ball of dough together.

Reduced antibody adaptability may make the elderly more vulnerable to influenza

The influenza vaccine may be less effective in the elderly because their B cells are less capable of producing antibodies that can adapt to protect against new viral strains, researchers report February 19 in the journal Cell Host & Microbe.

Novel ratiometric fluorescent probe for studying cellular activity of anticancer drug

NUS chemists have developed a novel ratiometric fluorescent probe for studying cellular activity of the clinically important anticancer drug cisplatin for next generation drug development.
