If coastal salt marshes are like savings accounts, with sediment as the principal, all eight Atlantic and Pacific coast salt marshes studied are "in the red," researchers found.

Scientists working on a rapid assessment technique for determining which US coastal salt marshes are most imperiled by erosion were surprised to find that all eight of the Atlantic and Pacific Coast marshes where they field-tested their method are losing ground, and half of them will be gone in 350 years’ time if they don’t recapture some lost terrain.

Tesla has always been about pushing full speed toward a tech-tastic future. CEO Elon Musk wouldn’t settle for making a luxurious, sexy, environmentally-friendly electric car. He made one that could hit 60 mph in 3.2 seconds. Then 2.8 seconds. Then 2.5—all the while ratcheting up the range, from the original 265 miles per charge to the current, top of the line 335.

Since the GOES-16 satellite lifted off from Cape Canaveral on November 19, scientists, meteorologists and ordinary weather enthusiasts have anxiously waited for the first photos from NOAA’s newest weather satellite, GOES-16, formerly GOES-R.

The release of the first images today is the latest step in a new age of weather satellites. It will be like high-definition from the heavens.

As Friday night became Saturday morning, Dong Kim sounded defeated.

Kim is a high-stakes poker player who specializes in no-limit Texas Hold ‘Em. The 28-year-old Korean-American typically matches wits with other top players on high-stakes internet sites or at the big Las Vegas casinos. But this month, he’s in Pittsburgh, playing poker against an artificially intelligent machine designed by two computer scientists at Carnegie Mellon. No computer has ever beaten the top players at no-limit Texas Hold ‘Em, a particularly complex game of cards that serves as the main event at the World Series of Poker. Nearly two years ago, Kim was among the players who defeated an earlier incarnation of the AI at the same casino. But this time is different. Late Friday night, just ten days into this twenty-day contest, Kim told me that he and his fellow humans have no real chance of winning.

ANU physicists have invented a tiny device that creates the highest quality holographic images ever achieved, opening the door to imaging technologies seen in science fiction movies such as Star Wars.
