New technique seamlessly converts ammonia to green hydrogen
Northwestern University researchers have developed a highly effective, environmentally friendly method for converting ammonia into hydrogen. The new technique is a major step forward for enabling a zero-pollution, hydrogen-fueled economy. The idea of using ammonia as a carrier for hydrogen delivery has gained traction in recent years because ammonia is much easier to liquify than hydrogen and is therefore much easier to store and transport. Northwestern's technological breakthrough overcomes several existing barriers to the production of clean hydrogen from ammonia.

Parental restrictions on tech use have little lasting effect into adulthood
A new study of more than 1,200 individuals found that time spent with digital technology during adolescence has little impact on long-term use, suggesting that worries about widespread tech addiction may be overblown. Parental limits on youth tech use had no lasting impact on use in adulthood.

Study finds health trade-offs for wildlife as urbanization expands
City living appears to improve reproductive success for migratory tree swallows compared to breeding in more environmentally protected areas, a new five-year study suggests. But urban life comes with a big trade-off - health hazards linked to poorer water quality.

Deep learning helps robots grasp and move objects with ease
Skyrocketing demand for online retail, triggered by the COVID-19 pandemic, has left many businesses struggling to fulfill orders while ensuring the safety of their warehouse employees. Researchers at the University of California, Berkeley, have created new artificial intelligence software that gives robots the speed and skill to grasp and smoothly move objects, making it feasible for them to soon assist humans in warehouse environments.

Novel magnetic spray transforms objects into millirobots for biomedical applications
An easy way to make millirobots by coating objects with a glue-like magnetic spray was developed in a joint research led by a scientist from City University of Hong Kong (CityU). Driven by the magnetic field, the coated objects can crawl, walk, or roll on different surfaces. As the magnetic coating is biocompatible and can be disintegrated into powders when needed, this technology demonstrates the potential for biomedical applications, including catheter navigation and drug delivery.

Algae breathe life into 3D engineered tissues
3D bioprinted algae can be harnessed as a sustainable source of oxygen for human cells in engineered vascularized tissues, researchers report November 18 in the journal Matter. They embedded the bioprinted photosynthetic algae, along with human liver-derived cells, in a 3D hydrogel matrix to create honeycomb-shaped tissues with lobules, similar to the human liver.

Piecing together the Alaska coastline's fractured volcanic activity
Among seismologists, the geology of Alaska's earthquake- and volcano-rich coast from the Aleutian Islands to the southeast is fascinating, but not well understood. Now, with more sophisticated tools than before, a University of Massachusetts Amherst team reports unexpected new details about the area's tectonic plates and their relationships to volcanoes.

Birds of a feather do flock together
Researchers explain how different species of the finch-like capuchino seedeaters quickly acquired distinct patterns of coloration over an evolutionary time scale. New gene patterns emerged from selective sweeps, a genetic process during which a naturally occurring variation becomes advantageous.

Driver behavior influences traffic patterns as much as roadway design, study reports

Experimenting in space to help prevent mudslides here on Earth
What can the International Space Station teach us about mudslides here on Earth? Here is the connection: UC San Diego engineers are trying to better understand the role gravity plays in mudslides. That is why in 18 months, they will launch an experiment to the ISS via SpaceX and NASA to study mudslides in microgravity. The work is funded by a $400,000 grant from the National Science Foundation.

Researcher gets NSF grant to study hidden messages in digital images
For more than 25 years, Binghamton University's Jessica Fridrich has studied digital-image steganography -- the science of hiding messages inside ordinary-looking photos. Just as technology has evolved and become more sophisticated, so have the methods to share secrets -- and a recent $768,964 grant from the National Science Foundation will help Fridrich stay ahead of the curve.

Childhood lead exposure leads to structural changes in middle-aged brains
More than three decades after they were found to have elevated blood lead levels as children, a group of middle-aged adults were found to have some small but significant changes in brain structure that corresponded to their dose of lead exposure in early life. MRI scans at age 45 revealed some small but significant changes in the brains of the people who had higher lead exposures measured at age 11.

Computer scientists launch counteroffensive against video game cheaters
University of Texas at Dallas computer scientists have devised a new weapon against video game players who cheat. The researchers developed their approach for detecting cheaters using the popular first-person shooter game Counter-Strike. But the mechanism can work for any massively multiplayer online (MMO) game that sends data traffic to a central server. Their research was published online Aug. 3 in IEEE Transactions on Dependable and Secure Computing.

New method brings physics to deep learning to better simulate turbulence
Deep learning, also called machine learning, reproduces data to model problem scenarios and offer solutions. However, some problems in physics are unknown or cannot be represented in detail mathematically on a computer. Researchers at the University of Illinois Urbana-Champaign developed a new method that brings physics into the machine learning process to make better predictions. The researchers used turbulence to test their method.
