Two of Mars' moons, Phobos and Deimos, have mysterious orbits. Deimos in particular, which orbits the Red Planet so closely that it circles the planet three times in just a single Earth day, has astronomers puzzled. Its orbit is at a two degree angle, something that researchers have mostly glossed over — until now. "The fact that Deimos's orbit is not exactly in plane with Mars's equator was cons
The ATM (ataxia-telangiectasia mutated) kinase is rapidly activated following DNA damage and phosphorylates its downstream targets to launch DDR signaling. Recently, we and others showed that UFM1 signaling promotes ATM activation. We further discovered that monoufmylation of histone H4 at Lys 31 by UFM1-specific ligase 1 (UFL1) is an important step in the amplification of ATM activation. However
In the equatorial regions on Earth today, the seasonal cycle of the monthly mean surface air temperature is 1 m) sand wedges were found near the paleoequator in the Marinoan glaciogenic deposits at ~635 million years ago, indicating a large seasonal cycle (probably >30°C). Through numerical simulations, we show that the equatorial seasonal cycle could reach >30°C at various continental locations
Nanomaterials often surprise us with unexpected phenomena. Here, we report a discovery of the anti-twinning deformation, previously thought impossible, in nanoscale body-centered cubic (BCC) tungsten crystals.

We demonstrate an effect whereby stochastic, thermal fluctuations combine with nonconservative optical forces to break detailed balance and produce increasingly coherent, apparently deterministic motion for a vacuum-trapped particle. The particle is birefringent and held in a linearly polarized Gaussian optical trap. It undergoes oscillations that grow rapidly in amplitude as the air pressure is
Prosocial behavior is paradoxical because it often entails a cost to one's own welfare to benefit others. Theoretical models suggest that prosociality is driven by several forms of reciprocity. Although we know a great deal about how each of these forms operates in isolation, they are rarely isolated in the real world. Rather, the topological features of human social networks are such that people
Eukaryotic protein synthesis control at multiple levels allows for dynamic, selective responses to diverse conditions, but spatial organization of translation initiation machinery as a regulatory principle has remained largely unexplored.

Individuals dating before ~4700 calendar years befor
The origin of carbonatites—igneous rocks with more than 50% of carbonate minerals—and whether they originate from a primary mantle source or from recycling of surface materials are still debated. Calcium isotopes have the potential to resolve the origin of carbonatites, since marine carbonates are enriched in the lighter isotopes of Ca compared to the mantle. Here, we report the Ca isotopic compo
Birefringence occurs when light with different polarizations sees different refractive indices during propagation. It plays an important role in optics and has enabled essential polarization elements such as wave plates. In bulk crystals, it is typically constrained to linear birefringence. In metamaterials with freeform meta-atoms, however, one can engineer the optical anisotropy such that light
