An international team of astronomers has reported the discovery of a new pulsar, which received the designation PSR J1631–4722. The newfound pulsar, which is young and energetic, turns out to be associated with a supernova remnant known as SNR G336.7+0.5. The finding was detailed in a research paper published Dec. 16 on the arXiv pre-print server.

Pulsars are highly magnetized, rotating neutron stars emitting a beam of electromagnetic radiation. They are usually detected in the form of short bursts of radio emission; however, some of them are also observed via optical, X-ray and gamma-ray telescopes.

Pulsars directly associated with known supernova remnants (SNRs) are generally rare as only dozens of such objects have been discovered to date. Finding these associations is crucial for astronomers as they could shed more light on pulsar formation history and supernova explosion mechanisms.

Some quantum fields that extend throughout all of space-time could be a rich resource of quantum entanglement that can be extracted forever.

Lunar rock and zircon ages were reset by a remelting event driven by the Moon’s orbital evolution, reconciling existing discrepancies in estimates for the formation time of the Moon and the crystallization time of its magma ocean.

If most robots still need remote human operators to be safe and effective, why should we welcome them into our homes?

Monitoring electrical signals in biological systems helps scientists understand how cells communicate, which can aid in the diagnosis and treatment of conditions like arrhythmia and Alzheimer’s.

But devices that record electrical signals in cell cultures and other liquid environments often use wires to connect each electrode on the device to its respective amplifier. Because only so many wires can be connected to the device, this restricts the number of recording sites, limiting the information that can be collected from cells.

MIT researchers have now developed a biosensing technique that eliminates the need for wires. Instead, tiny, wireless antennas use light to detect minute electrical signals.

Astrophycists from UCLan have determined that flat planets rather than spherical are the result of protoplanetary formation with the disk-instability theory.

While word-finding failures can be taken as evidence of memory problems, they may not be harbingers of befuddlement after all.

A glowing galaxy not far from the Milky Way has been harboring a strange, puzzling secret at its core.

In the center of NGC 5,084, some 80 million light-years away, the supermassive black hole around which the whole galaxy revolves has been discovered tipped over on its side, with its rotational axis parallel to the galactic plane.

Hallucinations, a bane of popular A.I. programs, turn out to be a boon for venturesome scientists eager to push back the frontiers of human knowledge.
