Scientists unravel key steps in the road to DNA repair

Researchers from Tokyo Metropolitan University have been studying DNA repair by homologous recombination, where the RecA protein repairs breaks in double-stranded DNA by incorporating a dangling single-strand end into intact ...

Suppressing the Auger recombination process in quantum dots

A Quantum Dot (QD) is a nanometer-sized semiconductor nanocrystal that has unique optical properties such as the ability to emit light in the range of optical frequencies depending on its size. QDs have already been applied ...

A new method for the fast detection of a key antiviral

Interferons are proteins that constitute an important part of our natural defense systems. These proteins also exhibit a remarkable antiviral activity. The recombinant human interferon α2b (rhIFNα2b) was approved by the ...

Human stem cell defenses activated by irradiation, study finds

Researchers from several Russian institutes, including MIPT, have found out how prolonged exposure to ionizing radiation affects human stem cells. They discovered that it causes a cell cycle delay, which leads to faster repairs ...

Understanding DNA Repair and Cancer

(PhysOrg.com) -- A protein that plays a key role in copying DNA also plays a vital role in repairing breaks in it, UC Davis scientists have found. The work is helping researchers understand how cancer cells can resist radiation ...

When editing bacteria with CRISPR, less is more

Systematically attenuating DNA targeting activity can achieve CRISPR-driven editing in bacteria, greatly boosting colony counts and even increasing the frequency of precise genome editing. This was shown in a study of the ...

Forks colliding: How DNA breaks during re-replication

Leveraging a novel system designed to examine the double-strand DNA breaks that occur as a consequence of gene amplification during DNA replication, Whitehead Institute scientists are bringing new clarity to the causes of ...

Physicists propose perfect material for lasers

Weyl semimetals are a recently discovered class of materials in which charge carriers behave the way electrons and positrons do in particle accelerators. Researchers from the Moscow Institute of Physics and Technology and ...
