The development of highly secure but simple and inexpensive encryption technology for the prevention of data leaks and forgeries is decidedly challenging. A research team has now introduced a 'double lock' based on thermoresponsive polymer hydrogels that encrypts information so that it can only be read at a specific window in temperature and time.

A new analysis of Tyrannosaurus skeletal remains reveals physical differences in the femur, other bones and dental structures across specimens that could suggest Tyrannosaurus rex specimens need to be re-categorized into three distinct groups or species, reports a new study.

An unnoticed network of channels is cutting across the coastal plain landscape along the Gulf Coast and influencing how water flows, according to new research that could help predict flooding from major storms in the future.

Atmospheric chemists have found that the smoke from Australia's 'Black Summer' wildfires set off chemical reactions in the stratosphere that contributed to the destruction of ozone. The study is the first to establish a chemical link between wildfire smoke and ozone depletion.

Researchers have developed an efficient concept to turn carbon dioxide into clean, sustainable fuels, without any unwanted by-products or waste.

The world's abalone are threatened, endangered or otherwise vulnerable in nearly every corner of the planet. If only we could wave a magic wand to know when abalone are ready to reproduce, without even touching them. Scientists have now found that wand -- although it isn't magic, and it only looks like a wand. It's an ultrasound transducer, and it can be used to quickly and noninvasively detect when abalone are ready to spawn, they report in a study this week.

Researchers have developed a new type of catalyst material, called a metal hydroxide-organic framework (MHOF), which is made of inexpensive and abundant components. The catalyst speeds up the electrochemical reaction that splits apart water molecules to produce oxygen, which is at the heart of multiple approaches aiming to produce alternative fuels for transportation.

Researchers have developed a computationally efficient method that could be used to identify anomalies in the U.S. power grid in real time. The novel technique augments a special type of machine-learning model with a powerful graph structure, and does not require any labeled data to train.

Researchers developed a technique that effectively protects computer programs' secret information from memory-timing side channel attacks, while enabling faster computation than other security schemes.

Scientists developed a neural network deep learning technique to extract hidden turbulent motion information from observations of the Sun. Tests on three different sets of simulation data showed that it is possible to infer the horizontal motion from data for the temperature and vertical motion. This technique will benefit solar astronomy and other fields such as plasma physics, fusion science, and fluid dynamics.

Lava domes form at the top of many volcanoes when viscous lava erupts. When they become unstable, they can collapse and cause a hazard. An international team of researchers has analyzed summit dome instabilities at Merapi Volcano, Indonesia. The researchers hope that by understanding the inner processes, volcano collapses can be better forecasted.

Axions are today's most popular candidate for dark matter, and numerous experiments are trying to detect them in microwave cavities where the axion should rarely convert into an electromagnetic wave. But a new simulation of the production of axions in the early universe provides a more refined mass estimate, and higher frequency for the EM wave, that is outside the range of these experiments. The new mass comes from adaptive mesh refinement in supercomputer simulations.

Ultrasound scans -- best known for monitoring pregnancies or imaging organs -- can also be used to stimulate cells and direct cell function. A team of researchers has developed an easier, more effective way to harness the technology for biomedical applications.

Despite California's computer science education policies, gender, racial and ethnic disparities persist among the high schools that offer these courses, the students enrolled in them and the faculty who teach them.

New research uncovers the negative link between flight-worthiness and fight-worthiness in birds. Evolutionary pressure demanded that birds could either fly or arm themselves -- but not both. Furthermore, the new research suggests that developing wings and not bony spurs involved both sexual and natural selection. This insight helps us better understand how the enormous diversity of life and earth came to be.

Time for a road trip. You punch the destination into your GPS and choose the suggested route. But is this shortest route the safest? Not necessarily, according to new findings.

The asteroid which killed nearly all of the dinosaurs struck Earth during springtime. This conclusion was drawn by an international team of researchers after having examined thin sections, high-resolution synchrotron X-ray scans, and carbon isotope records of the bones of fishes that died less than 60 minutes after the asteroid impacted.
