Laser melting: Fewer unknowns in the laser nanosynthesis of composites
Composite particles with submicron sizes can be produced by irradiating a suspension of nanoparticles with a laser beam. Violent physical and chemical processes take place during irradiation, many of which have been poorly understood to date. Recentl.....»»

Melting ice no guarantee of smooth sailing in fabled Arctic crossing: Study
Melting sea ice in the fast-warming Arctic Ocean is not making it easier for sailors to navigate a legendary shortcut between Europe and Asia despite popular belief, scientists said Thursday......»»
Melting high-mountain glaciers would release greenhouse gases into atmosphere, suggest scientists
The retreat of high mountain glaciers has accelerated since the 1980s, resulting in increased glacier runoff. However, it remains uncertain whether melting mountain glaciers enhance or release greenhouse gases, and whether areas exposed to glacier re.....»»
Studies unravel climate pattern impacts on the Antarctic Ice Sheet
New Monash research has untangled the influence of regional climate drivers, including the Southern Annular Mode (SAM) and the El Niño-Southern Oscillation (El Niño), on the Antarctic Ice Sheet. Snow accumulation and surface melting are two importa.....»»
This Brother printer is great, but here’s why you shouldn’t buy it
Brother's HL-L3280CDW color laser printer has a nice price, so I tested the quality, performance, and long-term value to see if it's right for you......»»
Scientists call for "major initiative" to study whether geoengineering should be used on glaciers
A group of scientists have released a landmark report on glacial geoengineering—an emerging field studying whether technology could halt the melting of glaciers and ice sheets as climate change progresses......»»

Super-resolution machining of single crystalline sapphire by femtosecond laser-induced, plasma-assisted ablation
A new study in Opto-Electronic Advances discusses super-resolution machining of single crystalline sapphire by GHz burst mode femtosecond laser-induced plasma assisted ablation......»»
Engineers develop advanced optical computing method for multiplexed data processing and encryption
Engineers at the University of California, Los Angeles (UCLA) have unveiled a major advancement in optical computing technology that promises to enhance data processing and encryption. The work is published in the journal Laser & Photonics Reviews......»»
Alaska’s top-heavy glaciers are approaching an irreversible tipping point
As the plateau of the icefield thins, ice and snow reserves at higher altitudes are lost. Enlarge / Taku Glacier is one of many that begin in the Juneau Icefield. (credit: Mauricio Handler / Getty Images) The melting of.....»»
Alaska"s top-heavy glaciers are approaching an irreversible tipping point
The melting of one of North America's largest icefields has accelerated and could soon reach an irreversible tipping point. That's the conclusion of new research colleagues and I have published on the Juneau Icefield, which straddles the Alaska-Canad.....»»
Controlling magnetism with polarized light: Non-thermal pathway uses inverse Faraday effect
Intense laser pulses can be used to manipulate or even switch the magnetization orientation of a material on extremely short time scales. Typically, such effects are thermally induced, as the absorbed laser energy heats up the material very rapidly,.....»»
Recovery of unique geological samples sheds light on formation of today"s Antarctic ice sheet
In recent years, global warming has left its mark on the Antarctic ice sheets. The "eternal" ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its fo.....»»
"Acceleration beats" shine bright light on a novel universal modulation regime in a semiconductor-based laser
Researchers at the Paul-Drude-Institute for Solid State Electronics (PDI) have observed a novel modulation regime characterized by the emergence of previously unseen "acceleration beats" in a modulated semiconductor-based laser......»»
NASA mission flies over Arctic to study sea ice melt causes
It's not just rising air and water temperatures influencing the decades-long decline of Arctic sea ice. Clouds, aerosols, even the bumps and dips on the ice itself can play a role. To explore how these factors interact and impact sea ice melting, NAS.....»»
Microscopic defects in ice influence how massive glaciers flow, study shows
As they seep and calve into the sea, melting glaciers and ice sheets are raising global water levels at unprecedented rates. To predict and prepare for future sea-level rise, scientists need a better understanding of how fast glaciers melt and what i.....»»
