It was big news years ago when Mars orbiters found streaks of what appeared to be water running down Martian cliffs and crater walls. Scientists worked hard to figure out what they were. Some proposed that they were seasonal streaks of briny ice, melting as the weak Mars summer arrived. New research says no to that.

Tracking exoplanets via orbital mechanics isn't easy. Plenty of variables could affect how a planet moves around its star, and determining which ones affect any given exoplanet requires a lot of data and a lot of modeling. A recent paper from researchers led by Kaviya Parthasarathy from National Tsing Hua University in Taiwan tries to break through the noise and determine what is causing the Transit Timing Variations (TTVs) of HAT-P-12b, more commonly known as Puli.

Extreme solar storms are a relatively rare event. However, as more and more of our critical infrastructure moves into space, they will begin to have more and more of an impact on our daily lives, rather than just providing an impressive light show at night. So it's best to know what's coming, and a new paper from an international team of researchers led by Kseniia Golubenko and Ilya Usoskin of the University of Oulu in Finalnd found a massive Extreme Solar Particle Event (ESPE) that happened 12350 years ago, which is now considered to be the most energetic on record.

Humans no longer have exclusive control over training social robots to interact effectively, thanks to a new study. The study introduces a new simulation method that lets researchers test their social robots without needing human participants, making research faster and scalable.

More than 400 underwater sites in the United States are potentially contaminated with unexploded ordnance -- weapons that did not explode upon deployment.

Researchers have developed a novel framework named WildFusion that fuses vision, vibration and touch to enable robots to 'sense' and navigate complex outdoor environments much like humans do.

Astronomers searching for massive black holes shredding stars found one in an unusual place -- 2,600 light years from the core of a galaxy. The roque black hole may be from an earlier merger with another galaxy, or have been tossed out of the core after interacting with two other black holes. This is the first ever optically discovered off-nuclear tidal disruption event. Eventually, the two could merge and produce ripples of gravitational waves.

A research team has developed a novel haptic device designed to enhance both safety and efficiency for workers in industrial settings.

Although glasses exhibit disordered atomic structures, X-ray and neutron scattering reveal a subtle periodicity. Researchers have demonstrated that this hidden periodicity -- referred to as 'invisible order' -- plays a critical role in determining vibrational fluctuations in the terahertz (THz) frequency range, which significantly influence the physical properties of glass.

A team of chemists has made significant strides in the field of mechanically interlocked molecules (MIMs). Their work showcases the development of a compact catenane with tuneable mechanical chirality, offering promising applications in areas such as material science, nanotechnology, and pharmaceuticals.

The largest sample of galaxy groups ever detected has been presented by a team of international astronomers using data from the James Webb Space telescope (JWST) in an area of the sky called COSMOS Web. The study marks a major milestone in extragalactic astronomy, providing unprecedented insights into the formation and evolution of galaxies and the large-scale structure of the universe.

Researchers analyzed a global database of 500,000 strange streaks that occur on steep Martian slopes, concluding that they're most likely caused by dry processes rather than liquid flow.

We need to learn our letters before we can learn to read and our numbers before we can learn how to add and subtract. The same principles are true with AI, a team of scientists has shown through laboratory experiments and computational modeling. In their work, researchers found that when recurrent neural networks (RNNs) are first trained on simple cognitive tasks, they are better equipped to handle more difficult and complex ones later on.

A new discovery could mean more donor hearts are available for heart transplant, giving more people a second chance at life.

Underwater or aerial vehicles with dimples like golf balls could be more efficient and maneuverable, a new prototype has demonstrated.

An unprecedented international effort to decode how cells manage the transport of chemical substances has culminated in four groundbreaking studies This decade-long project provides the first comprehensive functional blueprint of chemical transport pathways in human cells.

A team was able to show that swimming movements are possible even without a central control unit. This not only explains the behavior of microorganisms, it could also enable nanobots to move in a targeted manner, for example to transport drugs to the right place in the body.
