Using the Parkes radio telescope, Chinese astronomers have investigated an isolated pulsar known as PSR J1047−6709 and detected dozens of giant pulses during the bright state of this source. The finding is reported in a paper published December 10 on the arXiv pre-print repository.

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 using optical, X-ray and gamma-ray telescopes. To date, most pulsars have been discovered using the Parkes Observatory in Australia.

Some pulsars showcase the so-called giant pulses (GPs)—short-duration, burst-like radio emissions from a pulsar, with energies exceeding the average pulse energy by 10 times or even much more. So far, such activity has only been detected in 16 pulsars.

Hopefully they come up with a version with built in airconditioning for warm places. 😃

The team, led by Cornell postdoctoral researcher Jake D. Turner, Philippe Zarka of the Observatoire de Paris—Paris Sciences et Lettres University and Jean-Mathias Griessmeier of the Université d’Orléans published their findings in the forthcoming research section of the journal Astronomy & Astrophysics, on Dec. 16.

“We present one of the first hints of detecting an exoplanet in the radio realm,” Turner said. “The signal is from the Tau Boötes system, which contains a binary star and an exoplanet. We make the case for an emission by the planet itself. From the strength and polarization of the radio signal and the planet’s magnetic field, it is compatible with theoretical predictions.”

Researchers have identified a cancer-causing mutation in the PDGFRA gene that drives cell mutation and growth when activated. The findings have implications for the treatment of a subset of glioblastoma brain cancer.

Dead Cells

It’s an intriguingly microscopic example of pro-social behavior — an adaptation that doesn’t help an individual survive, but does let it use its death to help others, therefore making the entire swarm more likely to survive and reproduce.

“Dead cells are helping the community survive,” University of Texas at Austin professor of molecular biosciences told Live Science.

Here’s a tip.

On the 21 December solstice, the planets will look like one brilliant star as Jupiter’s and Saturn’s 12-and 29-year orbits bring them together. The last great conjunction was in May 2000, but its position in the sky meant it was difficult to see. The great conjunction of 1623 (when Galileo Galilei was still alive) was also hard to spot because, the Perth Observatory explains, it appeared close enough to the sun that it would have been “lost in the sun’s glare”.

“You’d have to go all the way back to just before dawn on 4 March 1226 to see a closer alignment between these objects visible in the night sky,” according to Patrick Hartigan, an astronomer from Rice University in Texas.

WASHINGTON (SBG) — Researchers studying cognitive deficits following traumatic brain injuries have discovered what they say is a revolutionary drug that could provide the cure for aging. The study by the University of California San Francisco has shown promising results among mice, essentially reversing age-related declines in memory. “We went on with this crazy experiment… and were able to return their cognitive function to as if they were never injured,” said Dr.
