Ribosomes found to be cause of somatic cell pluripotency

In 2012, a Japanese research group discovered that human skin cells acquire pluripotency when introduced to lactic acid bacteria. Now, the same group of researchers have found that the cause of somatic cell conversion into pluripotent stem cells is the ribosome, a protein synthesizing cellular organelle.

Inhaled carbon dioxide triggers group of neurons responsible for arousal

Breathing too much carbon dioxide can be deadly, but it can happen during sleep if a particular sleeping position causes an obstructed airway or because of a medical condition like sleep apnea.

The effects of Huntington’s disease can be seen as early as conception, finds new study

In a breakthrough study, scientists at the Rockefeller University have observed the effects of Huntington’s disease in neurons as early as conception.

Small tweak to mammal's DNA can cause significant physical changes, study finds

The difference between webbed toes and distinct digits may be the result of not just genetic information, but of how the genes regulate that information. Researchers at the National Institute of Genetics, Research Organization of Information and Systems in Japan found that a small, non-specific tweak to a mammal's DNA can potentially cause specific and significant physical changes.

Scientists elucidate surprising dual function of ceramide synthase

Scientists at the University of Bonn have clarified a surprising dual function of ceramide synthase. The enzyme not only catalyzes a central step of the production of vital lipids. It also has the ability to turn genes involved in lipid metabolism on or off. The study is being published in the renowned journal Cell Reports.

BIST researchers develop new retinal prosthesis to address visual degeneration

A healthy retina contains photoreceptor cells that convert light changes into nerve impulses, which are then carried along the optic nerve to the brain, where they are decoded into images. Diseases such as retinitis pigmentosa cause the photoreceptor cells to stop functioning, while the rest of the eye remains healthy.

Chinese researchers develop multifunctional vehicle to transport gene therapeutics

Gene editing is one of the hottest topics in cancer research. A Chinese research team has now developed a gold-nanoparticle-based multifunctional vehicle to transport the "gene scissors" to the tumor cell genome.

DNA study sheds light on longstanding puzzle of cell division

Scientists have solved a longstanding puzzle of how cells are able to tightly package DNA to enable healthy cell division.

Study reveals key mechanism of how cancer metastasis happens

Cancer metastasis, the migration of cells from a primary tumor to form distant tumors in the body, can be triggered by a chronic leakage of DNA within tumor cells, according to a team led by Weill Cornell Medicine and Memorial Sloan Kettering Cancer Center researchers.

Researchers find new way to halt growth of breast cancer cells

An international team of researchers led from Karolinska Institutet and Science for Life Laboratory in Sweden have found a new way of halting the growth of breast cancer cells.

Three-dimensional organization of genome plays key role in gene expression, cell fate

Scientists have long been reading the code of life - the genome -, as a sequence of letters but now researchers have also started exploring its three-dimensional organization.

EXD2 enzyme facilitates protein production in mitochondria

Researchers from the Genomic Instability and Cancer Laboratory at Institute for Research in Biomedicine (IRB Barcelona) have identified a key role for EXD2 in protein production in the mitochondria, the cellular organelles responsible for the majority of energy generation.

Cocaine de-addiction breakthrough shows promise

Researchers have successfully created a way by which cocaine craving could be reduced. This could help in the de-addiction of thousands of users feel experts. The team of researchers neutralized a protein molecule that is commonly seen among cocaine users in their blood and brain.
