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.....»»
Advance in photochemical water oxidation enhances sustainable energy potential
With the global shift towards sustainable and renewable energy, the urgency to develop efficient methods for producing clean energy has never been greater. Imagine a future where the energy that powers our homes and cities comes from one of the plane.....»»
Layer by layer: How simulations help manufacturing of modern displays
Modern materials must be recyclable and sustainable. Consumer electronics is no exception, with organic light-emitting diodes (OLEDs) taking over modern televisions and portable device displays. However, the development of suitable materials—from t.....»»
How a giant prehistoric elephant skull helped untangle an evolutionary mystery
About 400,000 years ago, early humans in Europe, Asia and Africa lived alongside giant straight-tusked elephants, far bigger than their modern-day cousins. Their evolution has long been a mystery to paleontologists, but an extraordinary, enormous and.....»»
Ancient clay remedy may have potential to boost modern gut health
A team of scientists has discovered that an ancient medicinal clay known as Lemnian earth (LE) could inspire new understanding of how to support present-day gut health......»»
Building concrete on Mars from local materials
Imagine you've just gotten to Mars as part of the first contingent of settlers. Your first challenge: build a long-term habitat using local materials. Those might include water from the polar caps mixed with specific surface soils. They might even re.....»»
Lake Michigan experiences warmest November in 30 years as climate change heats up the Great Lakes
Lake Michigan surface temperatures peaked at over 6 degrees above normal last month, the warmest they have been in November since 1995 when recordkeeping began at the National Oceanic and Atmospheric Administration. In the first two weeks of December.....»»
Mars orbiter spots retired InSight lander to study dust movement
NASA's Mars Reconnaissance Orbiter (MRO) caught a glimpse of the agency's retired InSight lander recently, documenting the accumulation of dust on the spacecraft's solar panels. In the new image taken Oct. 23 by MRO's High-Resolution Imaging Science.....»»
New study says we"re unlikely to find liquid water on Mars anytime soon
More than a hundred years ago, astronomer Percival Lowell made the case for the existence of canals on Mars designed to redistribute water from the Martian ice caps to its lower, drier latitudes. This necessarily meant the existence of Martians to bu.....»»
NASA orbiter captures one last image of retired InSight lander on Mars
An image from NASA's Mars Reconnaissance Orbiter shows one last view of the now-retired InSight lander mission......»»
Anthropologists call for tracking and preservation of human artifacts on Mars
Are human spacecraft, landers, rovers and other space-exploration debris little more than trash littering the surface of Mars, or the modern equivalent of Clovis points—treasured artifacts marking Homo sapiens' lust for new frontiers?.....»»
Oxidation in glacial rivers and lakes could help mitigate methane emissions
A new study offers a rare glimmer of hope in the face of climate change, suggesting glacial rivers and lakes may play a crucial role in mitigating the effects of methane—a powerful greenhouse gas that recent studies have shown emerges as glaciers m.....»»
NASA’s Mars rover just emerged from Jezero Crater. So, what next?
After a three-and-a-half month climb, NASA's Perseverance rover has finally reached the top of the Jezero Crater rim. So, what now?.....»»
Neanderthal-human interbreeding lasted 7,000 years, new study reveals
A new analysis of DNA from ancient modern humans (Homo sapiens) in Europe and Asia has determined, more precisely than ever, the time period during which Neanderthals interbred with modern humans, starting about 50,500 years ago and lasting about 7,0.....»»
Ancient genomes link early Europeans to Neanderthal ancestry
After modern humans left Africa, they met and interbred with Neanderthals, resulting in around 2–3% Neanderthal DNA that can be found in the genomes of all people outside Africa today. However, little is known about the genetics of these first pion.....»»
NASA honors Algerian parks with Martian namesakes
NASA's mapping of Mars now bears the names of three iconic Algerian national parks, Algerian physicist Noureddine Melikechi, a member of the US space agency's largest Mars probe mission, has told AFP......»»
Human settlement of Mars isn"t as far off as you might think
Could humans expand out beyond their homeworld and establish settlements on the planet Mars? The idea of settling the red planet has been around for decades. However, it has been seen by skeptics as a delusion at best and mere bluster at worst......»»
Catalyst "breathes" new life into acrylonitrile production
A team of engineers is reimagining one of the essential processes in modern manufacturing. Their goal? To transform how a chemical called acrylonitrile (ACN) is made—not by building world-scale manufacturing sites, but by using smaller-scale, modul.....»»
The ‘best OLED that LG has ever made’ is $500 off today
The 65-inch LG OLED Evo G4 TV, which we reviewed as "a triumph of modern television engineering," is on sale from Best Buy at $500 off. Don't miss this chance!.....»»
NASA believes it understands why Ingenuity crashed on Mars
Engineers are already beginning to plan for possible follow-on missions. Eleven months after the Ingenuity helicopter made its final flight on Mars, engineers and scientists at NA.....»»
