Researchers have uncovered how a key DNA repair enzyme is recruited and activated inside cells, answering long-standing questions about how cells protect and repair their DNA and providing the ...

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal metabolic processes or external stressors such as radiation or chemical ...

When Tomas Lindahl was failed in Chemistry in school. Image credit: Getty images The contrast is understated but striking: a student once failed in chemistry eventually redefining it. Born on January ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...

Medical scientist Eduardo Marbán – then at Johns Hopkins and now Cedars-Sinai – found that heart progenitor cells also have a special mechanism where they send out sacs, known as exosomes, which carry ...

Every great video starts with clean visuals. Whether you are editing product clips, tutorials, or social media content, having transparent backgrounds helps your videos look smooth and professional.

A clump of proteins seems to be in charge of the level of DNA repair that takes place in our bodies, determining how fast mutations accumulate in our cells over a lifetime – and might thus affect our ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

A new study uncovers how working at 35,000 feet may disrupt DNA repair and immune function in flight attendants, offering fresh insights into the health risks faced by cabin crews and the urgent need ...

A research team led by Professor ZHAO Guoping at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has unveiled a crucial mechanism that helps regulate DNA damage repair, ...
