Over the past century, 70 percent of beaches on the islands of Kaua'i, O'ahu, and Maui have had long-term erosion, according to a U.S. Geological Survey (USGS) and University of Hawai'i (UH) report released today.

They studied more than 150 miles of island coastline (essentially every beach) and found the average rate of coastal change – taking into account beaches that are both eroding and accreting – was 0.4 feet of erosion per year from the early 1900s to 2000s. Of those beaches eroding, the most extreme case was nearly 6 feet per year near Kualoa Point, East O'ahu.

You're in luck. To the consternation of advertisers, we gather almost no information about you so if you are concerned about outsiders learning a lot about you from your visit to this article, fear not.  If we were that clever, this site would make a lot of money.

What Facebook CEO Mark Zuckerberg calls “frictionless sharing” - like sharing music and book choices with the Internet - isn’t really frictionless – it forces on us the new frictions of worrying who knows what we’re reading and what our privacy settings are wherever and however we read electronically. It’s also not really sharing; real sharing is conscious sharing, a recommendation to read or not to read something rather than a data exhaust pipe of mental activity. 

Integrated circuit techniques can do just about anything - perhaps even help cure sepsis.

Margination is natural phenomenon where bacteria and leukocytes (white blood cells) move toward the sides of blood vessels. Now it's the inspiration for a novel method of treating sepsis, a systemic and often dangerous inflammatory response to microbial infection in the blood.

Anthropogenic climate change is so anthropomorphic.  While we think we have a mighty impact on the atmosphere, sauropod dinosaurs millions of years ago shouldn't be left out of the pollution hall of fame - they alone could have produced enough methane to warm the climate many millions of years ago, according to a numerical model.

Like CO2, methane is a greenhouse gas, but with 23X the warming impact of CO2. It's produced by dying plants and cow burps - and cows share one thing in common with hulking sauropods, distinctive for their enormous size and unusually long necks, that were widespread about 150 million years ago. As in cows, methane-producing microbes aided the sauropods' digestion by fermenting their plant food.

Among cancer deaths worldwide, lung cancer is the leader. 

It isn't just the tumor cells, the growth of blood vessels controls tumors development and blood vessel growth is controlled by several signalling molecules. Scientists have discovered a molecule, phosphodiesterase PDE4, that plays a key role in this process and they have succeeded in reducing tumor growth in their experiments by blocking it.

Stars live for a long time - millions of years - but near the end of their lives, some massive stars go through what astronomers call the yellow supergiant phase.

Because the timeframe is so short, cosmically, witnessing a yellow supergiant phase is rare - almost as rare as a Kardashian staying married when ratings slip.  Like with celebrity relationships, if you want to witness the big meltdown you have to stay vigilant in astronomy. And keep your camera running.
