Fourth Signature…

Topics: Condensed Matter Physics, Superconductor, Thermodynamics Researchers in the US report that they have observed the so-called “fourth signature” of superconducting phase transitions in materials known as cuprates. The result, obtained via photoemission spectroscopy of a cuprate called Bi2212, could shed fresh light on how these materials, which conduct electricity without resistance at temperatures ofContinue reading “Fourth Signature…”

Forging Ahead…

Topics: Battery, Biofuels, Climate Change, Existentialism, Global Warming Reducing carbon dioxide emissions and removing them from the atmosphere is critical to the global fight against climate change. Called decarbonization, it is one of the focal points in the nation’s strategy to ensure a bright future for our planet and all who live on it. TheContinue reading “Forging Ahead…”

Racing Green…

Topics: Alternate Energy, Battery, Biofuels, Climate Change, Global Warming Cars – and in particular racecars – might seem the villains in a world grappling with climate change. Racing Green: How Motorsport Science Can Change the World hopes to convince you of exactly the opposite, with science journalist Kit Chapman showing how motorsports not only pioneers new, planet-friendlierContinue reading “Racing Green…”

Dystopian and Unthinkable…

Topics: Civics, COVID-19, Epidemiology, Existentialism, Politics With all due respect to the recently departed former Secretary of State Madeline Albright, she started using the phrase “indispensable nation” after political reporter Sydney Blumenthal coined it. From Foreign Policy Magazine: In his memoir of the Clinton presidency, The Clinton Wars, Blumenthal elaborated on what the phrase was intended to represent: “OnlyContinue reading “Dystopian and Unthinkable…”

The Way It’s Supposed To Be…

Topics: Civilization, International Space Station, Politics, Space Exploration ALMATY, March 30 (Reuters) – A U.S. astronaut and two Russian cosmonauts safely landed in Kazakhstan on Wednesday after leaving the International Space Station aboard the same capsule despite heightened antagonism between Moscow and Washington over the conflict in Ukraine. The flight — carrying NASA’s Mark VandeContinue reading “The Way It’s Supposed To Be…”

Thermo Limits…

Topics: Climate Change, Computer Science, Electrical Engineering, Global Warming, Semiconductor Technology, Thermodynamics In case you had not noticed, computers are hot—literally. A laptop can pump out thigh-baking heat, while data centers consume an estimated 200 terawatt-hours each year—comparable to the energy consumption of some medium-sized countries. The carbon footprint of information and communication technologies asContinue reading “Thermo Limits…”

Getting Back Mojo…

Topics: Applied Physics, Lasers, Magnetism, Materials Science, Phonons When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10–15 seconds). The spin, or angular momentum, of the electrons in the material, thus disappears almost instantly. Yet all that angular momentum cannot simply be lost. It must be conservedContinue reading “Getting Back Mojo…”

Microbots and Chemo…

Topics: Biology, Cancer, Chemotherapy, Robotics Chemotherapy disrupts cancer cells’ ability to reproduce by frustrating cell division and damaging the cells’ DNA. In response to the pharmaceutical onslaught, cancer cells acquire mutations that reduce the therapy’s effectiveness. Compounding the challenge of fighting cancer: Under chemical and other stresses, mutation rates increase. A team led by PrincetonContinue reading “Microbots and Chemo…”

Quantum Charging…

Topics: Alternate Energy, Battery, Green Tech, Nanotechnology, Quantum Mechanics Note: I’m in the semifinals of the 3-Minute Thesis competition, so I decided to focus on my presentation. Wish me luck. This does, however, relate to our need as a species to get off fossil fuels as soon as possible, so things like Ukraine, Crimea, andContinue reading “Quantum Charging…”

Helium and Ukraine…

Topics: Chemistry, Instrumentation, Nuclear Magnetic Resonance, Physics, Research Scientists who need the gas face tough choices in the face of reduced supply and spiking prices. Helium supplies, already dicey, got worse this past week when production shut down in Arzew, Algeria. The curtailment joins ongoing disruptions in supplies from Russia and the US Federal Helium Reserve as wellContinue reading “Helium and Ukraine…”
