Today's 'Planet Earth Report' --Black Hat Cyber Attacks: “Can Morph Satellite Antennas Into Microwave Oven-like Weapons  

    The satellite communications that ships, planes and the military use to connect to the internet are vulnerable to hackers that, in the worst-case scenario, could carry out "cyber-physical attacks", turning satellite antennas into weapons that operate, essentially, like microwave ovens. According to research presented at the Black Hat information security conference in Las Vegas, continues Alex Hern in The Guardian, a number of popular satellite communication systems are ...

Today's Top Science Headline --"Our Universe Does Not Exist"  

    "The Cosmos must either be profoundly different than previously supposed or string theory must be wrong." On June 25, Timm Wrase awoke in Vienna and groggily scrolled through an online repository of newly posted physics papers. One title startled him into full consciousness. The paper, by the prominent string theorist Cumrun Vafa of Harvard University and collaborators, conjectured a simple formula dictating which kinds of universes are allowed to exist and which are forbidd

The Strange Life of Water on Alien Ultrahot Jupiters

"In this way, ultrahot Jupiters stretch out what we think planets should look like."

And the teeth would be about 7 inches or 17 centimeters tall, and it would have several rows in its mouth at once, so as it lost or broke teeth, it could easily replace them."

But nothing is as controversial, it turns out, as the debate over when the Santorini volcano actually erupted.

Mars' Discovery --Huge Lake of Liquid Water Observed Under South Pole: “We Were Not Seeing the Thing That was Right Under Our Noses"  

      On the surface, Mars is a barren land unchanged for hundreds of millions of years, motionless except for the scattering of powdery dust by a faint breeze, or the slow crawl of an alien rover. But just beneath the Martian soil, the picture is very different. New evidence suggests that far beneath the deeply frozen ice cap at Mars's south pole lies a lake of liquid water—the first to be found on the Red Planet. Detected from orbit using ice-penetrating radar, the l...

A team of astronomers has discovered a new way to unlock the mysteries of how the first galaxies formed and evolved.
