Optical data storage breakthrough increases capacity of diamonds by circumventing the diffraction limit
Physicists at The City College of New York have developed a technique with the potential to enhance optical data storage capacity in diamonds. This is possible by multiplexing the storage in the spectral domain. The research by Richard G. Monge and T.....»»
New technique efficiently offers insight into gene regulation
DNA is the most important carrier of genetic information. Each cell contains approximately two meters of DNA. To ensure that all this genetic material fits into the small cell nucleus, it must be tightly packed. The DNA is, therefore, wrapped around.....»»
Study illuminates formation of US east coast during break up of supercontinent Pangea
A recent study published in the Journal of Geophysical Research: Solid Earth sheds new light on the formation of the East Coast of the United States—a "passive margin," in geologic terms—during the breakup of the supercontinent Pangea and the ope.....»»
Telescopes didn"t always play nicely with each other. That"s about to change
Those readers who have dabbled with astronomical imaging will be familiar with the technique of taking multiple images and then stacking them together to improve the strength of the signal, yielding better images. Taking this technique further many r.....»»
Laser-induced hydrothermal growth for electrocatalytic applications
In the new study published in the journal International Journal of Extreme Manufacturing on 1 November 2023, researchers from the UK and China reported a novel technique based on a laser-induced hydrothermal reaction (LIHR) mechanism for the growth o.....»»
Unlocking long-term genetic memory: Dormant bacterial spores offer key insights into evolutionary survival strategies
A recent study spearheaded by Prof. Sigal Ben Yehuda and her team at Hebrew University has unveiled a captivating facet of bacterial dormancy. Their research illuminates the mechanism through which dormant bacterial spores uphold and activate an endu.....»»
