New discovery offers insight into how cells maintain the integrity of DNA

Researchers from Case Western Reserve University have identified a new mechanism by which a protein known for repairing damaged DNA also protects the integrity of DNA by preserving its structural shape.

Exposure to cannabis vapor reduces sperm counts and motility in two generations of mice

An intense but short-term exposure to cannabis vapor lowered sperm counts and slowed sperm movement, or motility, not only in the directly exposed male mice but also in their sons.

New study shows how neuroblastoma cells deal with rapid division

The cells of a certain tumor type, called neuroblastoma, divide very rapidly. This rapid division can have potentially fatal consequences for them. A new study shows how neuroblastoma cells deal with this dilemma.

Cellular enlargement drives a decline in function of stem cells, study suggests

MIT biologists have answered an important biological question: Why do cells control their size? Cells of the same type are strikingly uniform in size, while cell size differs between different cell types. This raises the question of whether cell size is important for cellular physiology.

'Mini brains' allow researchers to study a fatal, untreatable neurological disorder

Cambridge researchers have developed 'mini brains' that allow them to study a fatal and untreatable neurological disorder causing paralysis and dementia – and for the first time have been able to grow these for almost a year.

MIT researchers discover new way to awaken the immune system to attack tumors

Immunotherapy is a promising strategy to treat cancer by stimulating the body's own immune system to destroy tumor cells, but it only works for a handful of cancers. MIT researchers have now discovered a new way to jump-start the immune system to attack tumors, which they hope could allow immunotherapy to be used against more types of cancer.

Tumor suppressor protein binding to RNA also binds DNA, says study

Scientists from the Medical University of South Carolina earlier displayed how hnRNP E1 attaches to metastatic-linked RNAs to prevent their translation.

Study unravels the DNA repair mechanism by enzymes

A new study by researchers from the Gwangju Institute of Science and Technology in the Republic of Korea has revealed the mechanism of DNA repair by enzymes exonuclease III and polymerase I by utilizing single molecule fluorescence resonance energy transfer (smFRET)-enabled dynamic observation.

Study reveals how cells “read” synthetic ingredients added to a genetic code

If the genome is considered the recipe for life, then base pairs represent the individual ingredients. DNA is made up of these chemical structures, and every living thing on the planet has just four of them.

New “phase separation” protects against premature aging, neurological disorders

According to a new study, a mechanism through which an RNA, called NORAD, drives the Pumilio protein to create liquid droplets in cells—similar to oil in water—appears to closely control the activity of this protein.

New sunscreen is coral-safe and offers higher UVB/UVA protection

According to a new study reported in Nature Scientific Reports, Methylene Blue, a century-old medication, can be a very efficient, broad-spectrum UV irradiation protector that absorbs UVA and UVB, repairs ROS and UV irradiation-induced DNA damage, and is safe for coral reefs.
