The IceCube experiment in Antarctica has found that the Earth absorbs high-energy neutrinos:

Thanks to work at the IceCube instrument in Antarctica, we have learned that Earth has an appetite for high-energy neutrinos: they're more likely to be "swallowed" by the planet in collisions with matter than those at lower energies.

The bad news: sorry about "new physics" expectations. The result is in line with the boring old Standard Model of physics, and the observations seem to rule out more exotic theories involving compact spatial dimensions or the still-hypothetical leptoquark.

[...] The IceCube experiment was first frozen in 2010, and since then its 5,160 basketball-sized detectors have sought out tiny blue flashes of Cherenkov radiation emitted when a neutrino collides with the ice and releases particles such as muons.

In the Nature paper, the IceCube collaboration examined around 10,800 neutrino-related interactions to estimate the objects' direction of travel and energy.
