Teenage Maurice Sendak illustrated his teacher’s 1947 pop-sci book
Drawings of Atomics for the Millions "reveal early postwar anxieties about nuclear war." Enlarge / A young Maurice Sendak’s illustration of two possible outcomes of atomic power for the 1947 pop-sci book Atomics for the Million.....»»
Biomass-based polymer can capture and release CO₂ without high pressure or extreme temperatures
A new, biomass-based material developed by FAMU-FSU College of Engineering researchers can be used to repeatedly capture and release carbon dioxide......»»
Scientists use evolution to bioengineer new pathways to sustainable energy and pharmaceuticals
Using evolution as a guiding principle, researchers have successfully engineered bacteria-yeast hybrids to perform photosynthetic carbon assimilation, generate cellular energy and support yeast growth without traditional carbon feedstocks like glucos.....»»
Dissecting caspase-2-mediated cell death: From intrinsic PIDDosome activation to chemical modulation
Caspase-2, an initiator caspase, plays a critical role in programmed cell death in response to certain cellular stresses. Its activation is facilitated by the PIDDosome, a multi-protein complex that assembles under conditions of genotoxic stress. Des.....»»
Microscopic fossilized shells reveal ancient climate change patterns
At the end of the Paleocene and beginning of the Eocene epochs, between 59 to 51 million years ago, Earth experienced dramatic warming periods, both gradual periods stretching millions of years and sudden warming events known as hyperthermals......»»
A hybrid arrowhead against immune disorders: Bacterially derived natural product inhibits cellular immune response
The so-called immunoproteasome is essential for the cellular immune response. In autoimmune diseases, however, it is overactive. Until now, it has not been possible to selectively inhibit the immunoproteasome without disrupting other cellular mechani.....»»
Satellites reveal ecosystems most vulnerable to drought
More severe droughts that will also last longer: this will primarily be a problem for irrigated croplands, as discovered by environmental scientist Qi Chen. Mixed forests with a variety of plant species will be the least vulnerable. Chen compared the.....»»
Sustaining oyster farming with sturdier rafts
Amid the rising human population and pressure on food supplies, the world can't be everyone's oyster. But perhaps there might be more oysters to eat if an Osaka Metropolitan University-led research team's findings mean sturdy plastic rafts will be us.....»»
The Quantum Mechanics of the Greenhouse Effect
Carbon dioxide’s powerful heat-trapping effect has been traced to a quirk of its quantum structure. The finding may explain climate change better than any computer model......»»
New images reveal global air quality trends
The global concentrations of one of the main air pollutants known to affect human health has been graphically illustrated for the first time by a team of scientists......»»
Langbeinites show talents as 3D quantum spin liquids
A 3D quantum spin liquid has been discovered in the vicinity of a member of the langbeinite family. The material's specific crystalline structure and the resulting magnetic interactions induce an unusual behavior that can be traced back to an island.....»»
Ultra-sensitive photothermal microscopy technique detects single nanoparticles as small as 5 nm
