The result, published in the journal Science, does not define the exact mass of a neutrino, just its upper limit. But the finding helps bring physicists closer…

Even when the cable started sending back data, his first reaction was skeptical. “Rubbish,” Dr. Fichtner, a professor of seismology and wave physics at the Swiss university ETH Zurich,…

Oaks, some orchids, the potted spider plant in your office — they’re all capable of reproducing without a member of another sex nearby. “It makes sense if you are an organism that can’t run around and find mates,” said Deborah Charlesworth,…
