What causes pools below waterfalls to periodically fill with sediment?      (via sciencedaily.com) 

Deep pools below waterfalls are popular recreational swimming spots, but sometimes they can be partially or completely filled with sediment. New research showed how and why pools at the base of waterfalls, known as plunge pools, go through natural cycles of sediment fill and evacuation.

Grazing management of salt marshes contributes to coastal defense      (via sciencedaily.com) 

Combining natural salt marsh habitats with conventional dikes may provide a more sustainable alternative for fully engineered flood protection. Researchers studied how salt marsh management can be optimized for coastal defense purposes. They found that grazing by both cattle and small herbivores such as geese and hare and artificial mowing can reduce salt marsh erosion, therefore contributing to nature-based coastal defense.

Graphene key for novel hardware security      (via sciencedaily.com) 

As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components to create secure keys, but artificial intelligence (AI) techniques can be used to predict these keys and gain access to data. Now, researchers have designed a way to make the encrypted keys harder to crack.

An uncrackable combination of invisible ink and artificial intelligence      (via sciencedaily.com) 

Coded messages in invisible ink sound like something only found in espionage books, but in real life, they can have important security purposes. Yet, they can be cracked if their encryption is predictable. Now, researchers have printed complexly encoded data with normal ink and a carbon nanoparticle-based invisible ink, requiring both UV light and a computer that has been taught the code to reveal the correct messages.

Tremors triggered by typhoon talas tell tales of tumbling terrain      (via sciencedaily.com) 

A new method was developed for high-resolution detection of landslides based on seismic data. This method was applied to detect landslides that occurred during the transit of Typhoon Talas across western Japan in 2011. Multiple landslides were detected and located, including one in Shizuoka Prefecture, 400 km east of the typhoon's track. The results show that large and small landslides may follow the same scaling relationships. This method may help develop landslide emergency alert technology.

Facial recognition ID with a twist: Smiles, winks and other facial movements for access      (via sciencedaily.com) 

Concurrent Two-Factor Identity Verification requires both one's facial identity and a specific facial motion to gain access. To set it up, a user faces a camera and records a short 1-2 second video of either a unique facial motion or a lip movement from reading a secret phrase. The video is then input into the device, which extracts facial features and the features of the facial motion, storing them for later ID verification.

Sea level rise up to four times global average for coastal communities      (via sciencedaily.com)     Original source 

New research shows that coastal populations are experiencing relative sea-level rise up to four times faster than the global average. The study is the first to analyze global sea-level rise combined with measurements of sinking land. The impacts are far larger than the global numbers reported by the Intergovernmental Panel on Climate Change (IPCC). The high rates of relative sea-level rise are most urgent in South, South East and East Asia.
