Atmospheric oxidation and the creation of modern Mars
Like Earth, Mars was formed about 4.5 billion years ago, but its early surface was very different than today's. Mars' surface then had high rates of meteorite and asteroid impacts from the period known as the Late Heavy Bombardment. But whereas today.....»»
LIGO team enhances gravitational wave detection with squeezed light
A team of researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO), in the U.S., has developed what they describe as a squeezed light system to improve detection sensitivity......»»
You Asked: Laser TV vs. UX, speaker break-in tips, and re-boxing tales
On today’s You Asked: Laser TV versus a huge mini-LED TV. What happens to the TVs after we test them? And breaking in TV speakers — is that even a thing?.....»»
Researchers develop a laser that produces the strongest ultra-short laser pulses to date
The word laser usually conjures up an image of a strongly concentrated and continuous light beam. Lasers that produce such light are, in fact, very common and useful. However, science and industry often also require very short and strong pulses of la.....»»
Mars analog stations investigate lichen biodiversity during simulated missions
Once you know where to look for them, lichens are everywhere. These composite organisms—fungal and photosynthetic partners joined into a greater whole—can survive on a vast array of surfaces, from rocks and trees to bare ground and buildings. The.....»»
Researchers create a three-dimensional multi-focus laser for glass micro-sculpting
Glass materials are widely used in optical and optoelectronic devices due to their low cost and excellent mechanical and optical properties. Among them, glass concave/convex linear structures with feature sizes ranging from several micrometers to hun.....»»
How did magma oceans evolve on early Earth and Mars? Iron chemistry and primordial atmospheres offer clues
Before Earth became the blue planet, it was engulfed by a very different kind of ocean: a vast, deep magma ocean reaching down hundreds or perhaps even thousands of kilometers......»»

Hybrid fiber pump combiner could advance mid-IR laser systems
In the last two decades, the rapid advancement in applications such as environmental monitoring, medical diagnostics, and global positioning has intensified the focus on developing novel mid-IR light sources. Fiber-based mid-IR lasers, which operate.....»»
Perseverance team revives SHERLOC instrument to help with Jezero crater discovery
In January 2024, the SHERLOC instrument aboard NASA's Mars 2020 Perseverance rover encountered a significant issue. A fault in the instrument's motor caused the dust cover and autofocus mechanism to become inoperative, putting the rover's SHERLOC Ram.....»»
Curiosity rover provides new insights into how Mars became uninhabitable
NASA's Curiosity rover, currently exploring Gale crater on Mars, is providing new details about how the ancient Martian climate went from potentially suitable for life—with evidence for widespread liquid water on the surface—to a surface that is.....»»
Sacrificial burial confirms Scythians" eastern origins
Archaeologists have uncovered evidence for sacrificial funerary rituals at the Early Iron Age burial mound of Tunnug 1 in Tuva, Siberia, indicating that the horse-riding Scythian culture, best-known from Eastern Europe, originated far to the east......»»
