Laser Fusion Experiment Unleashes an Energetic Burst of Optimism
An anonymous reader quotes a report from The New York Times: Scientists have come tantalizingly close to reproducing the power of the sun -- albeit only in a speck of hydrogen for a fraction of a second. Researchers at Lawrence Livermore National Lab.....»»
Tropical and subtropical wind forcing could affect interannual variability of Kuroshio and Luzon undercurrent
Kuroshio in the western North Pacific is one of the world's most energetic western boundary currents. To the east of Luzon Island, the northward Kuroshio at its origin and the underlying southward Luzon Undercurrent (LUC), play an important role in s.....»»
Enhanced laser heterodyne spectroscopy helps atmospheric greenhouse gas measurements
A research team led by Prof. Gao Xiaoming from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has improved the measurement accuracy of atmospheric greenhouse gases, including carbon dioxide, by using an Erbium-doped Fiber.....»»
LIGO surpasses the quantum limit
In 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO), made history when it made the first direct detection of gravitational waves—ripples in space and time—produced by a pair of colliding black holes......»»
Carl Sagan detected life on Earth 30 years ago—here"s how his experiment is helping us search for alien species today
It's been 30 years since a group of scientists led by Carl Sagan found evidence for life on Earth using data from instruments on board the Nasa Galileo robotic spacecraft. Yes, you read that correctly. Among his many pearls of wisdom, Sagan was famou.....»»
"Mind-blowing": Astronomers spot most distant radio burst yet
Eight billion years ago, something happened in a distant galaxy that sent an incredibly powerful blast of radio waves hurtling through the universe......»»
Realizing vertical ultraviolet-B semiconductor laser diodes for high optical output
Ultraviolet (UV) rays are electromagnetic waves with wavelengths ranging from 100 to 380 nanometers (nm). These wavelengths can be classified into three regions: UV-A (315–380 nm), UV-B (280–315 nm), and UV-C (100–280 nm), with the latter two c.....»»
Astronomers detect most distant fast radio burst to date
An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory's (ESO) Very Larg.....»»
This dark nebula hides an enormous star
The birth of a star is a spectacular event that plays out behind a veil of gas and dust. It's a detailed process that takes millions of years to play out. Once a star leaves its protostar stage behind and begins its life of fusion, the star's powerfu.....»»
One of the best color laser printers just got a bit cheaper
The Brother HL-L3230CDW color laser printer, which is perfect for home offices and small businesses, is currently on sale from Amazon for an affordable $250......»»
X-ray lasers: Why does brighter mean darker?
When we illuminate something, we usually expect that the brighter the source we use, the brighter the resulting image will be. This rule also works for ultra-short pulses of laser light—but only up to a certain intensity. The answer to the question.....»»
Astronomers comb telescope archive and find microsecond-duration burst
An international team of researchers led by Dutch Ph.D. candidate Mark Snelders (ASTRON and University of Amsterdam) has discovered radio pulses from the distant universe that last only millionths of a second. They found these microsecond bursts afte.....»»
Researchers develop an innovative microscope platform to unveil the intricacies of skeletal muscle regeneration
Researchers at the Hong Kong University of Science and Technology (HKUST) have created a cutting-edge platform consisting of a dual-laser nonlinear optical microscope to investigate the dynamics of muscle satellite cells (MuSCs) during the process of.....»»
3D isotropic microfabrication in glass using spatiotemporal focusing of femtosecond laser pulses
Femtosecond (fs) laser direct writing (FLDW) is a laser micro/nano manufacturing technology that can focus the laser pulses on the surface or inside the material, causing local changes in material properties through nonlinear laser-material interacti.....»»
Widely tunable and high resolution mid-infrared laser based on optical parametric oscillator
A widely tunable and high resolution mid-infrared radiation source operating in the 3–5 µm region has been applied to numerous frontier applications, including remote sensing, molecular spectroscopy, and atmosphere environmental monitoring......»»
Physicists create new form of antenna for radio waves
University of Otago physicists have used a small glass bulb containing an atomic vapor to demonstrate a new form of antenna for radio waves. The bulb was "wired up" with laser beams and could therefore be placed far from any receiver electronics......»»
These Gene-Edited Chickens Were Made to Resist Bird Flu
Avian influenza can wipe out entire poultry flocks. An early experiment with Crispr suggests that gene editing can protect chickens against infection......»»
NASA’s Psyche Mission Is Off to Test a Space Laser (for Communications)
The Psyche probe is heading to its namesake metal-rich asteroid. Along the way, it will demonstrate a near-infrared laser system to send high-rate data hundreds of millions of miles home......»»
