As the supersonic solar wind surges towards Earth, its interaction with our planet's magnetic field creates a shock to deflect its flow, and a foreshock filled with electromagnetic waves. How these waves can propagate to the other side of the shock has long remained a mystery.

A team is collecting data that will be used to create models that can help improve lava flow forecasting tools that are useful in determining how hazards impact populations. One such tool, known as MOLASSES, is a simulation engine that forecasts inundation areas of lava flow.

Changes in Earth's orbit that favored hotter conditions may have helped trigger a rapid global warming event 56 million years ago. Researchers found the shape of Earth's orbit, or eccentricity, and the wobble in its rotation, or precession, favored hotter conditions at the onset of the PETM and that these orbital configurations together may have played a role in triggering the event.

The first global analysis of larval orientation studies found that millimeter-size fish babies consistently use external cues to find their way in the open ocean.  There are many external cues available to marine fish including the Sun, Earth's magnetic field, and sounds. The new study offers important insight into understanding this perilous phase of marine fish.

Evidence that a complete stress release may have contributed to the 2011 Tohoku earthquake that broke records. Both sedimentary formations above and below the plate boundary fault lie in the stress state of normal faults in which vertical stress is greater than maximum horizontal stress. The new data show good consistency with previous results above the fault -- at the boundary between the North American plate and the subducting Pacific plate -- suggesting that combining geophysical data and core samples to comprehensively investigate stress states is effective.

Researchers are hoping that a new, low-cost battery which holds four times the energy capacity of lithium-ion batteries and is far cheaper to produce will significantly reduce the cost of transitioning to a decarbonized economy.

Scientists used high energy x-rays to investigate the solid-electrolyte interphase, a chemical layer in batteries that's key to stabilizing lithium metal anodes. Chemists unraveled this complex chemical mechanisms that is crucial for boosting energy density.

Engineering researchers have developed a battery-free, pill-shaped ingestible biosensing system designed to provide continuous monitoring in the intestinal environment. It gives scientists the ability to monitor gut metabolites in real time, which wasn't possible before. This could unlock a new understanding of intestinal metabolite composition, which significantly impacts human health overall.

Earthquakes are notoriously hard to predict, and so too are the usually less-severe aftershocks that often follow a major seismic event.

Lithium-ion batteries with high-energy-density cathodes are necessary to meet the energy demands of next-generation electronics and electric vehicles. At high voltages, however, the battery electrolyte undergoes excessive decomposition, compromising cathode performance. To tackle this, researchers have now synthesized a bio-based, non-toxic additive material that stabilizes the cathode by forming a passivation layer on its surface and suppressing its decomposition. Eco-friendly and low-cost, the novel compound could promote a wider utilization of bio-based resources.

Nanoengineers have developed an AI algorithm that predicts the structure and dynamic properties of any material -- whether existing or new -- almost instantaneously. Known as M3GNet, the algorithm was used to develop matterverse.ai, a database of more than 31 million yet-to-be-synthesized materials with properties predicted by machine learning algorithms. Matterverse.ai facilitates the discovery of new technological materials with exceptional properties.
