Relationship between two natural enemies of brown marmorated stink bug pest

The brown marmorated stink bug feeding on a cherry. Credit: CABI A new CABI-led study has examined the relationship between two closely-related natural enemies of the brown marmorated stink bug in respect of how they interact when trying to attack the fruit and nut pest’s egg masses. The brown marmorated stink bug is a global… Continue reading Relationship between two natural enemies of brown marmorated stink bug pest

Landing Therapeutic Genes Safely in the Human Genome – Improving Gene and Cell Therapies

By Wyss Institute for Biologically Inspired Engineering at Harvard January 24, 2022 A collaborative research team at Harvard’s Wyss Institute and the ETH Zurich in Switzerland has identified genomic safe harbors (GSHs) in the tumultuous sea of human genome sequence to land therapeutic genes in. As part of their validation, they inserted a fluorescent GFP… Continue reading Landing Therapeutic Genes Safely in the Human Genome – Improving Gene and Cell Therapies

Clearer distinction needed between GMOs and genome-edited organisms

Graphical abstract. Credit: DOI: 10.1016/j.tibtech.2021.11.001 Researchers from Hokkaido University have proposed a framework to assist in the demarcation between genetically modified organisms and genome-edited organisms, taking into account both scientific and socio-ethical considerations. Producers have been breeding plants and animals for desired traits, including higher yields, better taste and flavor, and disease resistance for millennia.… Continue reading Clearer distinction needed between GMOs and genome-edited organisms

Broccoli compound triggers controlled cell death and recycling of cellular components in fission yeast

Broccoli may contain advantages beyond nutrition. A molecule found in broccoli, cabbage and more digests down into DIM, a compound with brighter benefits than the name implies, such as inducing cell death in breast, prostate and colon cancer. Now, researchers are beginning to understand the mechanism underpinning this molecular behavior — information that could help… Continue reading Broccoli compound triggers controlled cell death and recycling of cellular components in fission yeast

How does mercury accumulation vary in tropical forests?

Spatial distribution of surface soil Hg concentration in tropical forests of Xishuangbanna. Credit: Xia Shangwen As a global pollutant, mercury (Hg) is emitted directly into the atmosphere from geogenic and anthropogenic sources and previously deposited Hg in natural surfaces. Previous studies in subtropical evergreen forests have shown that climate, vegetation and terrain factors shape Hg… Continue reading How does mercury accumulation vary in tropical forests?

Fat’s unexpected role in muscle stem cell fate

Satellite cells differentiate into muscle cells or self-renew depending on the level of lipid droplets in the cell. Shihuan Kuang, a Purdue University professor of animal sciences, showed for the first time that fat inside adult muscle stem cells regulates their fate. Credit: Purdue University/Shihuan Kuang Scientists have shown for the first time that fat… Continue reading Fat’s unexpected role in muscle stem cell fate

LED Lighted Nets Dramatically Reduce Bycatch of Wildlife While Making Fishing More Efficient

A new study finds that using lighted nets greatly reduced accidental bycatch of sharks, rays, sea turtles, and unwanted finfish. Credit: NOAA Fisheries LED illuminated nets reduce bycatch of sharks and skates by an incredible 95 percent while maintaining catch rates of target species. In a win-win for commercial fisheries and marine wildlife, researchers have… Continue reading LED Lighted Nets Dramatically Reduce Bycatch of Wildlife While Making Fishing More Efficient
