How to keep Earth from being cooked by the ever-hotter Sun
Here are two options for future humans to keep us in the habitable zone. I’d wager a guess that we are, as a species, rather fond of our home planet (our wanton carbon emissions notwithstanding). But the ugly truth is that the Eart.....»»
Optical amplifier and record-sensitive receiver pave the way for faster space communication
In space exploration, long-distance optical links can now be used to transmit images, films and data from space probes to Earth using light. But in order for the signals to reach all the way and not be disturbed along the way, hypersensitive receiver.....»»
How life began on Earth: Model suggests ancient Earth had organic-rich atmosphere
The key to unlocking the secrets of distant planets starts right here on Earth. Researchers at Tohoku University, the University of Tokyo, and Hokkaido University have developed a model that considers various atmospheric chemical reactions to estimat.....»»

Volcanic "cryptic carbon" emissions may be a hidden driver of Earth"s past climate
An international team of geoscientists led by a volcanologist at Rutgers University-New Brunswick has discovered that, contrary to present scientific understanding, ancient volcanoes continued to spew carbon dioxide into the atmosphere from deep with.....»»
"Halloween comet" breaks apart after flying close to the sun
A recently discovered comet that some stargazers had hoped to see during Halloween week has disintegrated before the day of ghosts and ghouls......»»
AMD vs. Intel: which makes the best CPUs?

Gold bugs: New fossil arthropod preserved in fool"s gold
A team of researchers led by Associate Professor Luke Parry, Department of Earth Sciences, University of Oxford, have unveiled a spectacular new 450-million-year-old fossil arthropod (the group that contains spiders, centipedes, and insects). Besides.....»»
Engineered bacterial protein offers efficient rare earth metal separation
A newly discovered protein naturally houses an unusual binding site that can differentiate between rare earth elements, and researchers at Penn State have made it even better. Rare earth elements are key components used in everything from modern tech.....»»
Tracking a disappearing mantle plume in ancient Samoa: Researchers shed light on a 30-million-year gap
When plumes of magma well up through Earth's lithosphere, they create volcanoes, islands, seamounts, and other features on the surface. Telltale hot spot tracks form as tectonic plates move over these plumes, marking plume locations and the movement.....»»
Dinosaurs thrived after ice, not fire, says a new study of ancient volcanism
201.6 million years ago, one of the Earth's five great mass extinctions took place, when three-quarters of all living species suddenly disappeared. The wipeout coincided with massive volcanic eruptions that split apart Pangaea, a giant continent then.....»»
Hera asteroid mission"s CubeSat passengers signal home
The two CubeSat passengers aboard ESA's Hera mission for planetary defense have exchanged their first signals with Earth, confirming their nominal status. The pair were switched on to check out all their systems, marking the first operation of ESA Cu.....»»
How Earth"s Early Life Thrived amid Catastrophic Asteroid Impacts
A gigantic space rock that slammed into Earth more than three billion years ago grievously wounded the biosphere—and then helped it heal.....»»
Plans to Destroy the International Space Station Preview a Bigger Orbital Junk Problem
A special spacecraft will guide the space station through Earth’s atmosphere, but what about other large pieces of space debris?.....»»
Novel self-cleaning electrode developed for alkaline-earth metal peroxide synthesis
Metal peroxide (MO2, M=Ca, Sr, Ba) is an alternative to hydrogen peroxide (H2O2). It has excellent oxidative properties, superior chemical stability, high purity, and is easy to store and transport. It has been widely used in wastewater treatment and.....»»

New deep ultraviolet micro-LED array advances maskless photolithography
A team led by Prof. Sun Haiding from the University of Science and Technology of China (USTC) developed a vertically integrated micro-scale light-emitting diode (micro-LED) array which was then applied in deep ultraviolet (DUV) maskless photolithogra.....»»
Did some of Earth"s water come from the solar wind?
The source of Earth's water is an enduring mystery that extends to exoplanets and the notion of habitability. In broad terms, Earth's water was either part of the planet from the beginning of its formation in the solar nebula or delivered later, mayb.....»»

Four astronauts returned to Earth on Friday after a nearly eight-month space station stay extended by Boeing's capsule trouble and Hurricane Milton......»»
Saturn"s moon Titan has insulating methane-rich crust up to six miles thick
Saturn's largest moon, Titan, is the only place other than Earth known to have an atmosphere and liquids in the form of rivers, lakes and seas on its surface. Because of its extremely cold temperature, the liquids on Titan are made of hydrocarbons li.....»»
