n a major breakthrough in the fields of nanophotonics and ultrafast optics, a research team has demonstrated the ability to dynamically steer light pulses from conventional, so-called incoherent light sources.

Researchers created a system that enables makers to incorporate sensors directly into rotational mechanisms with only one pass in a 3D printer. This gives rotational mechanisms like gearboxes the ability to sense their angular position, rotation speed, and direction of rotation.

An increasing number of U.S. interstates are set to try out an invention that could save millions of taxpayer dollars and significantly reduce traffic delays. The invention, a sensor that allows concrete to 'talk,' decreases construction time and how often concrete pavement needs repairs while also improving the road’s sustainability and cutting its carbon footprint. Embedded directly into a concrete pour, the sensor sends engineers more precise and consistent data about the concrete’s strength and need for repair than is possible with currently used tools and methods.

In a new study, astronomers describe how extraterrestrial life has the potential to exist on distant exoplanets inside a special area called the 'terminator zone,' which is a ring on planets that have one side that always faces its star and one side that is always dark.

Venus appears to have volcanic activity, according to a new research paper that offers strong evidence to answer the lingering question about whether Earth's sister planet currently has eruptions and lava flows.

Researchers report abnormalities in functional neural networks of dogs diagnosed with anxiety. The study shows that compared with healthy dogs, those with anxiety exhibit stronger connections between the amygdala and other regions of the anxiety network. The findings might also help reveal how functional connections between anxiety-related regions of the brain are altered in cases of human anxiety disorders.

The Notre-Dame de Paris is the first known cathedral of Gothic-style architecture to be initially constructed with extensive use of iron to bind stones together. The 2019 fire that significantly damaged the cathedral enabled analyses leading to this discovery.

Researchers have developed resilient artificial muscles that can enable insect-scale aerial robots to effectively recover flight performance after suffering severe damage.

Scientists revealed the discovery of a relict glacier near Mars' equator. Located in Eastern Noctis Labyrinthus at coordinates 7° 33' S, 93° 14' W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant implications for future human exploration.

The Walking Oligomeric Robotic Mobility System, or WORMS, is a reconfigurable, modular, multiagent robotics architecture for extreme lunar terrain mobility. The system could be used to assemble autonomous worm-like parts into larger biomimetic robots that could explore lava tubes, steep slopes, and the moon's permanently shadowed regions.

Thanks to technological advances in microbial DNA analysis, researchers have discovered that mountaineers' boots aren't the only things leaving footprints on the world's tallest mountain. When someone sneezes on Everest, their germs can last for centuries.

In an unlikely pairing, a chemist and an astrophysicist applied the tools of statistical mechanics to find similarities in spatial patterns across length scales.

After an earthquake, it is crucial in the early phase of disaster management to obtain a rapid assessment of the severity of the impact on the affected population in order to be able to initiate adequate emergency measures. A first quick and good assessment of whether an earthquake causes severe or minor damage can often be given after only 10 minutes by information from affected people about the 'felt intensity' of the earthquake.

A new study suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle.

Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth's inner core, according to seismologists.

New research on friction between faults could aid in predicting the world's most powerful earthquakes. Researchers discovered that fault surfaces bond together, or heal, after an earthquake. A fault that is slow to heal is more likely to move harmlessly, while one that heals quickly is more likely to stick until it breaks in a large, damaging earthquake. Tests allowed them to calculate a slow, harmless type of tremor. The discovery alone won't allow scientists to predict when the next big one will strike but it does give researchers a valuable new way to investigate the causes and potential for a large, damaging earthquake to happen, and guide efforts to monitor large faults like Cascadia in the Pacific Northwest.

Cornell University researchers have unearthed precise, microscopic clues to where magma is stored, offering a way to better assess the risk of volcanic eruptions.
