Maternal diets rich in Omega-3 fatty acids may protect offspring from breast cancer
In a new study recently published by Frontiers in Cell and Developmental Biology, Marshall University researchers noted a significant difference in mice from mothers that were fed a diet rich in canola oil, compared with mothers fed a diet rich in corn oil. A maternal Omega 3-rich diet affected genome-wide epigenetic landscape changes in offspring and potentially modulated gene expression patterns.

Old oil fields may be less prone to induced earthquakes
Subsurface carbon sequestration--storing carbon in rocks deep underground--offers a partial solution for removing carbon from the atmosphere. Used alongside emissions reductions, geologic carbon sequestration could help mitigate anthropogenic climate change. But like other underground operations, it comes with risks--including earthquakes.

Pop-up coffee table -- no assembly required
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Harvard Graduate School of Design have developed a deployable system that is light, compact, inexpensive, easy to manufacture, and, most importantly, easy to deploy. By harnessing the mechanical instabilities in curved beams, the system can transform objects into elaborate and customizable 3D configurations on a range of scales, from large-scale furniture to small medical devices.

New type of metasurface allows unprecedented laser control
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have developed a single metasurface that can effectively tune the different properties of laser light, including wavelength, without the need of additional optical components. The metasurface can split light into multiple beams and control their shape and intensity in an independent, precise and power-efficient way.

Post-pandemic rehabilitation
The year 2020 was a period of economic hardship and significant change in a wide range of sectors for most countries. A team of authors from HSE University has explored how Russia will recover from this crisis and which industries will be affected by the economic recovery. Their study was published in the journal Voprosy ekonomiki.

Drone tech's next big target: insect pest management
Drones keep getting smaller, while their potential applications keep getting bigger. And now unmanned aircraft systems are taking on some of the world's biggest small problems: insect pests. From crop-munching caterpillars to disease-transmitting mosquitoes, insects that threaten crops, ecosystems, and public health are being targeted with new pest-management strategies that deploy drones for detection and control. A variety of these applications are featured in a new special collection in the Journal of Economic Entomology.

Unique exoplanet photobombs CHEOPS study of nearby star system
While studying two exoplanets in a bright nearby star system, the CHEOPS satellite has unexpectedly spotted the system's third known planet crossing the face of the star. This transit reveals exciting details about a rare planet "with no known equivalent", as the scientific team led by the Universities of Geneva and Bern, and members of the National Center of Competence in Research PlanetS, point out.
