Nuclear radiation used to transmit digital data wirelessly Posted: 10 Nov 2021 10:15 AM PST Engineers have successfully transferred digitally encoded information wirelessly using nuclear radiation instead of conventional technology. The researchers measured the spontaneous emission of fast neutrons from californium-252, a radioactive isotope produced in nuclear reactors. Several examples of information, i.e., a word, the alphabet and a random number selected blindly, were encoded serially into the modulation of the neutron field and the output decoded on a laptop which recovered the encoded information on screen. Fast neutrons have an advantage over conventional electromagnetic waves, which are significantly weakened by transmission through materials including metals.

New method to detect Tatooine-like planets validated Posted: 10 Nov 2021 10:15 AM PST A new method has allowed scientists to quickly detect a transiting planet with two suns.

Tread lightly: ‘Eggshell planets’ possible around other stars Posted: 10 Nov 2021 07:46 AM PST Strange 'eggshell planets' are among the rich variety of exoplanets possible, according to a study. These rocky worlds have an ultra-thin outer brittle layer and little to no topography. Such worlds are unlikely to have plate tectonics, raising questions as to their habitability. Planetary geologists have said at least three such worlds found during previous astronomical surveys may already be known.

Rapidly evolving species more likely to go extinct, study suggests Posted: 10 Nov 2021 07:46 AM PST Researchers have found that fast evolution can lead to nowhere.

Underbite regained: Species feared extinct is the only frog with true teeth on its lower jaw Posted: 10 Nov 2021 07:45 AM PST In a new study, biologists laid to rest a century-old debate by confirming that a single species of frog, out of the more than 7,000 living today, has true teeth on its lower jaw.

Partial skull of a child of Homo naledi: Insight into stages of life of remarkable species Posted: 04 Nov 2021 07:06 AM PDT Researchers have revealed the first partial skull of a Homo naledi child that was found in the remote depths of the Rising Star cave in Johannesburg, South Africa. The team announced the discovery of parts of the skull and teeth of the child that died almost 250,000 years ago.
