BLM Protesters Call For Defunding San Bernardino Police After Officer Kills Armed Black Suspect. Sat, 10/24/2020 - 10:45. The nationwide fervor that drove millions of white college students out into the streets to protest systemic racism and police brutality has since cooled, probably because, once the dust settled, most normal people had a second to survey the facts and realize that thousands of unarmed black men actually aren't being killed by police every year in the US (the real figure is closer to 9). But that hasn't stopped a core contingent of BLM protesters from carrying on with their radical demands to defund police, seizing on every police-involved shooting, regardless of the circumstances, to create chaos and push their radical age.
Self‐assembly is important for creating photonic structures, and structural color is tunable typically relying on size‐varied building blocks obtained by time‐consuming chemical synthesis. Herein, molecular conformation of bottlebrush block copolymers (BBCPs) in solution is successfully manipulated to create libraries of photonic structures . Amphiphilic BBCPs bearing oxidation‐responsive ferrocene groups on the hydrophilic block are used to fabricate porous particles via evaporation‐induced self‐assembly of water‐in‐oil‐in‐water (O/W/O) double emulsions stabilized by the BBCP surfactant. In‐situ oxidation of the ferrocene groups by hydrogen peroxide at the W/O interface leads to enhanced hydrophilicity, more hydration, and chain extension
Transient signaling orchestrates complex spatiotemporal behaviour in living organisms via (bio)chemical reaction networks (CRNs). Compartmentalization of signal‐processing is an important aspect for controlling such networks. However, artificial CRNs mostly focus on homogeneous solutions to program autonomous self‐assembling systems, which limits their accessible behaviour and tuneability. Here, we introduce layered compartments housing antagonistic pH‐modulating enzymes, and demonstrate that transient pH signals in a supernatant solution can be programmed based on spatial delays. This overcomes limitations of activity mismatches of antagonistic enzymes in solution and allows to flexibly program acidic and alkaline pH lifecycles beyond poss.

It would be nearly impossible for anyone to not know this was an election year at this point. Between the presidential debates and all the political ads running on TV, the election is difficult to escape. NASA astronaut Kate Rubins is encouraging people to vote by pointing out that she voted from space. A picture was posted to the NASA …

Entomologists in Washington state on Thursday the first Asian giant hornet nest in the U.S. Why it matters: You may know this insect species by its nom de guerre: "the murder hornet." While the threat they pose to humans has been overstated, the invading hornets could decimate local honeybee populations if they establish themselves. How it works: The giant hornets, which are native to east Asia, grow as long as two inches and use spiked mandibles to decapitate honeybees. They have also been known to attack animals and human beings using a stinger long enough to puncture a beekeeper's protective suit and venom that the New York Times as "hot metal driving into their skin.". In Japan they're known to kill , though in fairness to the murder hor.

New Delhi: China has illegally occupied Nepal’s land at several places spreading over seven bordering districts and Indian intelligence agencies have sounded an alert in New Delhi. The agencies have flagged that Beijing is fast moving forward and further pushing Nepali boundaries by encroaching more and more landmass. “The actual scenario could be worse as the […]
