What those canyons are on Saturn’s moon Titan — A network of dark canyons lines Saturn’s moon, Titan, but just what’s inside those trenches has remained mysterious – until now. Researchers just confirmed that those canyons are flowing with liquid methane. The answer to that question finally came when NASA’s Cassini radar spotted glints off of the canyons’ surfaces.

Venus may have supported life before Earth — Climate models show the hellish planet may have held liquid water for billions of years. Despite being much closer to Earth than Mars, its climate has average temperatures of 462°C (864°F), crushing barometric pressure and it has loads of volcanoes. Yet as soon as 750 million years ago, it may have had oceans of liquid water and an Earth-like, habitable climate, according to simulations from NASA Goddard Institute researchers.
~ It’s closer to the sun but the real problem is a massive greenhouse effect.
Lakes of Mars — Scientists just produced stronger evidence that Mars once had water lakes that may have nurtured life. After combing over Curiosity rover data, the researchers determined that veins in places like the planet’s Gale Crater were likely created by evaporating lakes whose sediments were buried, heated and corroded.
~ It may once even have been lush.
Juno probe closer to Jupiter — The spacecraft just completed the closest approach it will take during its primary mission around the gas giant, passing a mere 4184 kms (2600 miles) above the surface.
~ It’s doing more sweeps between now and February.
A lab-made black hole supports longstanding Hawking theory —
‘Hawking radiation’ suggests black holes can evaporate, and new evidence supports Stephen Hawking’s 1974 hypothesis.
~ This was proved with a Sonic Black Hole that won’t swallow your lab.
Super-resilient ceramic could be the key to future spacecraft — Russia’s Tomsk State University is developing a ceramic with multiple layers (based on hafnium carbide, zirconium diboride and zirconium oxide) that can survive temperatures over 3000°C (5400F). Even the best metal alloys can’t usually handle more than 2000C (3600F), the university says.
~ And they thought its inventor was a mug …
People will lie to robots to avoid hurting their feelings — Research carried out by the University College London (UCL) and the University of Bristol shows people will lie to robots to spare their ‘feelings’!
~ And they’re scared robots will one day be cleverer than us!
Smartphone sensor peers through walls — A new sensor for Android smartphones called the WalabotDIY promises to let your device peer right through walls revealing everything from pipes, to wiring, to even unwanted pests hiding between rooms.
~ I hope it can see I prefer iPhone.
Six innovative rooftop solar technologies — Sun-powered roofs aren’t new, but some recent innovations make them more affordable and easier to install, from tiles to shingles to ‘icy glass’.
~ I like the shiny ones (main picture, above).
Sea anemones could be the key to treating hearing loss — Researchers have discovered that proteins used by starlet sea anemones to repair their cells also repair the sound-sensing cells in mice and other mammals.
~ So one day maybe they can repair human hearing, too.
North American settlement went differently than thought — A new study published in Nature points out, the math of the accepted narrative of human settlement of the Americas simply doesn’t add up. It’s now thought more likely that early North Americans made their way past the ice sheets by either walking along the ice-free sections of the coastal beaches, or more speculatively, by sea travel.
~ DNA should help to confirm the theory.
