As scientists around the globe join efforts to understand brain function, we enter the era of Big Data and stir up debate on how science is done and how it can affect us all.
DNA is replicated to pass genetic information to the daughter cells during cell proliferation. Replication errors, if not repaired, can lead to genetic mutations. For an individual organism, some DNA mutations may cause disease, even lethality. Robust DNA repair system exists in cells to ensure efficient correction of replication errors, to safeguard genetic fidelity. However, a small percentage of replication errors escapes from DNA repair, and provides an important basis for evolution.
A team involving Kobe University researchers has succeeded in developing Target-AID, a genome editing technique that does not cleave the DNA. The technique offers a method to address the existing issues of genome editing. It is expected that the technique will be applied to gene therapy in the future in addition to providing a powerful tool for breeding useful organisms and conducting disease and drug-discovery research.
Electronic components have become faster and faster over the years, thus making powerful computers and other technologies possible. Researchers at ETH Zurich have now investigated how fast electrons can ultimately be controlled with electric fields. Their insights are of importance for the petahertz electronics of the future.
Dong Chunhua's group and Zou Changling from the Key Laboratory of Quantum Information, University of Science and Technology of China of the Chinese Academy of Sciences first experimentally demonstrated non-magnetic non-reciprocity using optomechanical interactions in a whispering gallery microresonator. This work was published in Nature Photonics.
Banning tobacco sales within 1,000 feet of schools could reduce socioeconomic and racial/ethnic disparities in tobacco density across neighborhoods, according to a study being published today in the journal Nicotine & Tobacco Research.
Several species of bacteria found in smokeless tobacco products have been associated with opportunistic infections, according to a paper published Aug. 26 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
Research led by SUNY Downstate Medical Center shows that, at the onset of puberty, the emergence of a novel inhibitory brain receptor, α4βδ (alpha four beta delta), reduces seizure-like activity in a mouse model of epilepsy.
A team of researchers has announced the development of a novel small-molecule Wnt inhibitor named NCB-0846. Wnt signaling is a key pathway of cancer stem cell development. The inhibitor may provide a new therapy option for patients with drug-refractory colorectal cancer.
Researchers analyzed an online medical forum to better understand what patients want to know about e-cigarettes and how doctors respond to those questions.
