New Study of Neanderthal And Denisovan DNA Reveals a Surprising Link to Men Today...
Neanderthal teeth from Spy 94a in Belgium. (I. Crevecoeur/Max Planck Institute for Evolutionary Anthropology) Decades of teasing apart Neanderthal DNA has produced an archive of ancient genes that spell out a history of love affairs between estranged branches of humanity's family tree. Until now, the story has been rather lopsided. For whatever reason, the most…
Astronomers Just Revealed One of The Most Extreme Planets Ever Discovered – ScienceAlert
Astronomers have taken detailed observations of an incredibly extreme exoplanet, detecting brutal surface temperatures in the region of 3,200 degrees Celsius (5,792 degrees Fahrenheit). Those temperatures – measured by the European Space Agency's CHaracterising ExOPlanet Satellite (or CHEOPS) – are enough to melt all rocks and metals, and even turn them into a gaseous form.While the exoplanet,…
Mutations that affect aging: More common than we thought? – Phys.org
The researchers at Linköping University used fruit flies to study mutations that could contribute to ageing. Credit: Magnus Johansson/Linköping University The number of mutations that can contribute to aging may be significantly higher than previously believed, according to new research on fruit flies. The study by scientists at Linköping University, Sweden, supports a new theory…
3 more ancient underground lakes of liquid water discovered on Mars, raising possibility of...
Two years ago, astronomers reported findings of a large lake beneath a thick layer of ice at Mars' south pole. Now, scientists have confirmed that finding and detected three new underground lakes in the same area — and they believe there could be many more. A new study, published this week in the journal Nature…
Planet collision simulations give clues to atmospheric loss from moon’s origin – Phys.org

The Ocean Is Becoming More Stable, And The Consequences May Be Dire, Scientists Warn...
KELLY MACNAMARA, AFP 29 SEPTEMBER 2020 Global warming is making the oceans more stable, increasing surface temperatures and reducing the carbon they can absorb, according to research published Monday by climate scientists who warned that the findings have "profound and troubling" implications. Man-made climate change has increased surface temperatures across the planet, leading to atmospheric…

SpaceX lends Starlink to Washington emergency services as Elon Musk talks IPO – Teslarati
SpaceX has provided Washington’s Emergency Management department access to Starlink satellite internet service in a bid to support the state’s emergency response to dangerous wildfires. Though the customer is technically a military department, this is the first public announcement of the internet constellation’s use in a civil service-oriented role. In the case of Malden, WA,…

See the First Eerie NASA Images of DART’s Asteroid Crash Site – CNET
On Monday, the world watched as a little NASA spacecraft called DART met its explosive end. This box, slightly bigger than an oven and winged with solar panels, had been fated to die since it left Earth in November. The Double Asteroid Redirection Test's mission was simple: Crash into a large asteroid so scientists can see whether…
Uncovering Hidden Patterns: AI Reduces a 100,000-Equation Quantum Physics Problem to Only Four Equations...
Abstract quantum physics illustration.Scientists trained a machine learning tool to capture the physics of electrons moving on a lattice using far fewer equations than would typically be required, all without sacrificing accuracy.A daunting quantum problem that until now required 100,000 equations has been compressed into a bite-size task of as few as four equations by…
