The Mountains of Pluto are Snowcapped, but not for the same reasons as on Earth

In 2015, the New Horizons space probe discovered spectacular snowcapped mountains on Pluto, which are strikingly similar to mountains on Earth. Such a landscape had never before been observed elsewhere in the Solar System. However, as atmospheric temperatures on our planet decrease at altitude, on Pluto they heat up at altitude as a result of solar radiation.

So where does this ice come from? An international team led by CNRS scientists* conducted this exploration...

Technique to Recover Lost Single-Cell RNA-sequencing Information

Seq-Well resolution example
MIT researchers have greatly boosted the amount of information that can be obtained using Seq-Well, a technique for rapidly sequencing RNA from single cells. This advance should enable scientists to learn much more about the critical genes that are expressed in each cell, and help them to discover subtle differences between healthy and dysfunctional cells for designing new preventions and cures. This image illustrates the improved resolution, right, using the new technique.

Boosting the efficiency of single-cell RNA-sequencing helps reveal subtle differences between healthy and dysfunctional cells. Sequencing RNA from individual cells can reveal a great deal of information about what those cells are doing in the body...

Researchers are working on Tech so Machines can Thermally ‘Breathe’

UCF researchers working on a cooling system for electronics
UCF mechanical and aerospace engineering researchers Khan Rabbi and Shawn Putnam are developing new ways to cool machines and electronics. Rabbi is a doctoral candidate in the department, and Putnam is an associate professor.

In the era of electric cars, machine learning and ultra-efficient vehicles for space travel, computers and hardware are operating faster and more efficiently. But this increase in power comes with a trade-off: They get superhot.

To counter this, University of Central Florida researchers are developing a way for large machines to “breathe” in and out cooling blasts of water to keep their systems from overheating.

The findings are detailed in a recent study in the journal Physical Review Fluids.

The process is much like how humans and some animals breath in...

Astronomers Solve Dark Matter Puzzle of Strange Galaxy

Image and amplification (in colour) of the ultra-diffuse galaxy Dragonfly 44 taken with the Hubble space telescope. Many of the dots on the galaxy are the globular clusters studied in this article to explore the distribution of dark matter. The galaxy is so diffuse that other galaxies can be seen behind it.

Astronomers have found that the total number of globular clusters around Dragonfly 44 and, therefore, the dark matter content, is much less than earlier findings had suggested, which shows that this galaxy is neither unique nor anomalous.

At present, the formation of galaxies is difficult to understand without the presence of a ubiquitous, but mysterious component, termed dark matter. Astronomers have measure how much dark matter there is around galaxies, and have found that it varies between 10 and 300 times the quantity of visible matter...
