Separating out signals recorded at the seafloor
Blame it on plate tectonics. The deep ocean is never preserved, but instead is lost to time as the seafloor is subducted. Geologists are mostly left with shallower rocks from closer to the shoreline to inform their studies of Earth history......»»
Could interstellar quantum communications involve Earth or solve the Fermi paradox?
Thus far, the search for extraterrestrial intelligence (SETI) has used strategies based on classical science—listening for radio waves, telescopes watching for optical signals, telescopes in orbit scouring light from the atmospheres of exoplanets,.....»»
DNA origami and fluorescent probes can precisely release molecular cargo
In the world of nanotechnology, the development of dynamic systems that respond to molecular signals is becoming increasingly important. The DNA origami technique, whereby DNA is programmed so as to produce functional nanostructures, plays a key role.....»»
Reinventing the clock: NASA"s new tech for space timekeeping
Here on Earth, it might not matter if your wristwatch runs a few seconds slow. But crucial spacecraft functions need accuracy down to one billionth of a second or less. Navigating with GPS, for example, relies on precise timing signals from satellite.....»»
Huge gamma-ray burst collection "rivals 250-year-old Messier catalog," say astronomers
Hundreds of gamma-ray bursts (GRBs) have been recorded as part of an enormous global effort so extensive it "rivals the catalog of deep-sky objects created by Messier 250 years ago", astronomers say......»»
Shallow waters make the best carbon sinks, researchers find
Marine phytoplankton take up atmospheric carbon and carry it to the seafloor when they die and sink (a process known as organic carbon sedimentation). This biological carbon pump is a powerful part of Earth's carbon cycle, yet scientists don't have a.....»»
Magna CEO says North American contract assembly plant unlikely amid heightened uncertainty
Magna is pumping the brakes on a potential North American vehicle assembly plant as the supplier signals a more cautious approach to its contract manufacturing business......»»
Chemical chameleon reveals novel pathway for separating rare-earth metals
Researchers at the Department of Energy's Oak Ridge National Laboratory have found a chemical "chameleon" that could improve the process used to purify rare-earth metals used in clean energy, medical and national security applications......»»
Pausing biological clock could give boost to lab-produced blood stem cells
A decade ago, Raquel Espin Palazon discovered that inflammatory signaling pathways must switch on for embryos to produce blood stem cells. The latest work from her lab shows the potential value of keeping those same signals switched off after their i.....»»
June-August 2024 were hottest ever recorded: EU monitor
The 2024 northern summer saw the highest global temperatures on record, beating 2023's high and making this year likely Earth's hottest ever recorded, the EU's climate monitor said Friday......»»

Plasmonic modulators could enable high-capacity space communication
Researchers have achieved data rates as high as 424Gbit/s across a 53-km turbulent free-space optical link using plasmonic modulators—devices that use special light waves called surface plasmon polaritons to control and change optical signals. The.....»»
Nanostructures enable on-chip lightwave-electronic frequency mixer
Imagine how a phone call works: Your voice is converted into electronic signals, shifted up to higher frequencies, transmitted over long distances, and then shifted back down so it can be heard clearly on the other end. The process enabling this shif.....»»
Climate scientist: Broken temperature records are alarming, but it is not too late to limit global warming
July 22, 2024 was the hottest day in recorded human history, with a global average temperature of 17.16 C......»»
Blood puddles, mold, tainted meat, bugs: Boar’s Head inspections are horrifying
The USDA recorded 69 violations in a year. So far, 9 people have died in the outbreak. Enlarge / A recall notice is posted next to Boar's Head meats that are displayed at a Safeway store on July 31, 2024, in San Rafael, Californi.....»»
Plant signaling pathways decoded using "optogenetic" tobacco plants
Using newly generated "optogenetic" tobacco plants, research teams from the University of Würzburg's Departments of Plant Physiology and Neurophysiology have investigated how plants process external signals......»»
Proteins for skin strength also control cell signaling, study suggests
An extensive family of proteins that gives human skin mechanical strength also appears to organize molecular signals that control skin cell activity, a study led by UT Southwestern Medical Center researchers shows. The team's findings, published in D.....»»
Salesforce is betting more personalized connected cars will make money
Salesforce's investment in a new connected car application signals the company's confidence in the promise of connectivity......»»
Spider exploits firefly"s flashing signals to lure more prey
Fireflies rely on flashing signals to communicate to other fireflies using light-emitting lanterns on their abdomens. In fireflies of the species Abscondita terminalis, males make multi-pulse flashes with two lanterns to attract females, while female.....»»
Geophysicists find link between seismic waves called PKP precursors and strange anomalies in Earth"s mantle
For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth's lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds......»»
Researchers develop a test bed for separating valuable material on the moon
It's often better to flesh out technologies fully on Earth's surface before they're used in space. That is doubly true if that technology is part of the critical infrastructure keeping astronauts alive on the moon......»»
