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.

Another celestial treat to look out for in the run-up to Christmas.

This week Jupiter and Saturn are low in the southwest during the chilly December dusk. When this month began, they were separated by 2.1 degrees.

But in the days that followed, they have been slowly approaching each other; getting closer by about 0.1 degrees each day on their way toward the long-awaited “great conjunction” next Monday evening (Dec. 21). Their inching closer to each other will be further enlivened by the passage on Wednesday and Thursday evenings (Dec. 16–17) of a foreground waxing crescent moon.

Researchers at EPFL have developed an approach to print tiny tissues that look and function almost like their full-sized counterpart. Measuring just a few centimeters across, the mini-tissues could allow scientists to study biological processes—and even test new treatment approaches—in ways that were previously not possible.

For years, mini versions of organs such as the brain, kidney and lung—known as “organoids”—have been grown from stem cells. Organoids promise to cut down on the need for animal testing and offer better models to study how human organs form and how that process goes awry in disease. However, conventional approaches to grow organoids result in stem cells assembling into micro-to millimeter-sized, hollow spheres. “That is non-physiological, because many organs, such as the intestine or the airway, are tube-shaped and much larger,” says Matthias Lütolf, a professor at EPFL’s Institute of Bioengineering, who led the study published today in Nature Materials.

There was nothing technical or physical stopping us from having moved on from Apollo to a permanent Moonbase, the development of industries in space and the establishment of the first human communities on Mars.

While in his time the reason “Why?” was derived from war, this time it can be born of hope.
