Researchers create a new 3D extra-large pore zeolite that opens a new path to the decontamination of water and gas

in in-the-news
An international team of researchers, with the participation of the Spanish National Research Council (CSIC), has created the most porous stable zeolite known to date, a new pure silica zeolite called ZEO-3. This zeolite was formed by an unprecedented topotactic condensation of a 1D silicate chain to a 3D zeolite. Read Full Article Here source: Phys.org

Scientists demonstrate quantum recoil for the first time, paving the way for precise X-ray imaging

in in-the-news
source: Phys.org For the first time since it was proposed more than 80 years ago, scientists from Nanyang Technological University, Singapore (NTU Singapore) have demonstrated the phenomenon of “quantum recoil,” which describes how the particle nature of light has a major impact on electrons moving through materials. The research is published online today (January 19) in the journal Nature Photonics. Read Full Article Here

Study reveals key aspect of the finely tuned regulation of gene expression

in in-the-news
Your skin cells are clearly different from your brain cells even though they both develop in the same person and carry the same genes. They are different because each cell type expresses a particular set of genes that is different from the ones expressed by the other. This is possible thanks to cellular mechanisms that tightly regulate gene expression. Read Full Article Here source: Phys.org

Summer heat waves and low oxygen prove deadly for bay scallops as a New York fishery collapses

in in-the-news
A new study by Stony Brook University researchers published in Global Change Biology demonstrates that warming waters and heat waves have contributed to the loss of an economically and culturally important fishery, the production of bay scallops. As climate change intensifies, heat waves are becoming more and more common across the globe. In the face of such repeated events, animals will acclimate, migrate, or perish.

The genes that made whales gigantic

in in-the-news
source: Phys.org New research published in Scientific Reports reveals the genes that likely allowed whales to grow to giant sizes compared to their ancestors. The findings highlight the role of four genes (called GHSR, IGFBP7, NCAPG, and PLAG1), and suggest that they promote large body sizes while mitigating potentially negative effects, such as increased cancer risk.

Using cancer cells as logic gates to determine what makes them move

in in-the-news
Cancer cells migrate through the body for multiple reasons; some are simply following the flow of a fluid, while others are actively following specific chemical trails. So how do you determine which cells are moving and why? Purdue University researchers have reverse-engineered a cellular signal processing system and used it like a logic gate—a simple computer—to better understand what causes specific cells to migrate.

What makes brown rice healthy? Decoding the chemistry of its nutritional wealth

in in-the-news
source: Phys.org Asian diets feature rice as a staple grain, contributing towards nearly 90% of the world’s rice consumption. Brown rice, in particular, is known to have several health benefits. As a regular addition to the diet, it can help reduce body weight, lower cholesterol, and suppress inflammation. The ability of brown rice to neutralize reactive oxygen species and prevent cellular damage is vital to many of its health-promoting effects. Although previous studies have shown that the antioxidant compounds in brown rice can protect cells against oxidative stress, knowledge regarding which major compound contributes towards these beneficial properties has long remained a mystery.

17-pound meteorite discovered in Antarctica

in in-the-news
source: Phys.org Antarctica is a tough place to work, for obvious reasons—it’s bitterly cold, remote, and wild. However, it’s one of the best places in the world to hunt for meteorites. That’s partly because Antarctica is a desert, and its dry climate limits the degree of weathering the meteorites experience. On top of the dry conditions, the landscape is ideal for meteorite hunting: the black space rocks stand out clearly against snowy fields.

Agave gene delays poplar dormancy, study finds

in in-the-news
source: Phys.org A team of scientists led by Oak Ridge National Laboratory discovered the gene in agave that governs when the plant goes dormant and used it to create poplar trees that nearly doubled in size, increasing biomass yield for biofuels production and carbon sequestration.

Billions of celestial objects revealed in gargantuan survey of the Milky Way

in in-the-news
source: Phys.org Astronomers have released a gargantuan survey of the galactic plane of the Milky Way. The new dataset contains a staggering 3.32 billion celestial objects—arguably the largest such catalog so far. The data for this unprecedented survey were taken with the Dark Energy Camera, built by the US Department of Energy, at the NSF’s Cerro Tololo Inter-American Observatory in Chile, a Program of NOIRLab.

Definite spectroscopic evidence for magnetic reconnection in splitting of solar filament structure

in in-the-news
source: Phys.org Magnetic reconnection is a universal process that changes magnetic topology and converts magnetic energy to plasma kinetic energy. Spatially resolved spectroscopic observations covering extended regions in the solar atmosphere are rare, and thus the distribution and energy partition of reconnection remain unclear.

Five ways to make part-time working easier and more available, according to new research

in in-the-news
source: Phys.org Economic inactivity and the rising cost of out-of-work benefits are high on the UK government’s agenda right now. But new research into working patterns during the COVID furlough scheme suggests that both employers and the government could be missing a trick in this area by not making part-time working easier and more available.

How mycorrhizal types control biodiversity effects on productivity

in in-the-news
source: Phys.org Mycorrhizal symbiosis helps plants expand their root surface area, giving plants greater access to nutrients and water. Although the first and foremost role of mycorrhizal symbiosis is to facilitate plant nutrition, how mycorrhizal types mediate the nutrient acquisition and interactions of coexisting trees in forests has not been clear to scientists.
