ALMA digs deeper into the Mystery of Planet Formation

Images of disks around 19 protostars, including 4 binary systems observed with ALMA. For 1 binary system, disks around the primary and secondary are presented independently (2nd line rightmost and 3rd line leftmost). Disks are presented in the order of their evolutionary sequence (the one in the upper-left corner is the youngest while the one at the lower-right corner is the oldest). The two oldest disks show faint ring-gap structures. A scale bar of 20 au (roughly the distance between the Sun and Uranus) is shown for each disk image. (Credit: ALMA (ESO/NAOJ/NRAO), N.

An international research team used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe disks around 19 protostars with a very high resolution to search for the earliest...

‘Smiling cat’ Sh2-284 nebula captured in new image

In the centre of this image is a large cloud, orange and red in colour, which is stretched out over the majority of the frame. The region in the top left of the cloud is particularly vivid. All around the image there are stars, in different colours of white, orange and purple. Some of these are smaller, background stars, whereas others reside in the foreground of the image, such as those in the central cluster of the nebula.
The Sh2-284 nebula, imaged by the VLT Survey Telescope

This cloud of orange and red, part of the Sh2-284 nebula, is shown here in spectacular detail using data from the VLT Survey Telescope, hosted by the European Southern Observatory (ESO). This nebula is teeming with young stars, as gas and dust within it clumps together to form new suns. If you take a look at the cloud as a whole, you might be able to make out the face of a cat, smiling down from the sky.

The Sh2-284 stellar nursery is a vast region of dust and gas and its brightest part, visible in this image, is about 150 light-years (over 1400 trillion kilometers) across. It’s located some 15,000 light-years away from Earth in the constellation Monoceros.

Nestled in the center of the brightest part of the nebula—right under...

Researchers reveal how Cells Rewrite their Fate

Researchers at the Centre for Genomic Regulation (CRG) in Barcelona and the Max Delbrück Center for Molecular Medicine in the Helmholtz Association in Berlin have revealed how cells accelerate changes to their identity, a process known as cell fate conversion.

The study, published today in the journal eLife, has implications for cancer research as the disease often arises from errors in cell fate decisions. The study could eventually lead to new methods of accelerating or manipulating the molecular mechanisms involved in the formation of cancer.

Central to the study is C/EBPα...

Corporate Collaboration bolster Quantum Encryption

Toshiba Europe and global telecommunications corporation Orange say they have achieved a significant advance in securing network communications from ever-more powerful computer attacks.

Security experts have been warning that a new generation of quantum computers is likely only a few years away from attaining the ability to crack today’s stringent public key encryption codes.

Some experts say quantum computers will be strong enough to crack the widely adopted RSA-2048 encryption standard for secure online transactions within about 15 years. The Cloud Security Alliance had a more dire—and precise—prediction: Encryption safeguards will be overtaken by April 14, 2030...
