Neutron-star cores contain matter at the highest densities reached in our present-day universe, with as much as two solar masses of matter compressed inside a sphere of 25 km in diameter. These astrophysical objects can indeed be thought of as giant atomic nuclei, with gravity compressing their cores to densities exceeding those of individual protons and neutrons many-fold.

These densities make neutron stars interesting astrophysical objects from the point of view of particle and nuclear physics. A longstanding open problem is whether the immense central pressure of neutron stars can compress protons and neutrons into a new phase of matter, known as cold quark matter. In this exotic state of matter, individual protons and neutrons no longer exist.

“Their constituent quarks and gluons are instead liberated from their typical color confinement and are allowed to move almost freely,” explains Aleksi Vuorinen, professor of theoretical particle physics at the University of Helsinki.

Japan’s space agency announced Thursday it will launch its next-generation H3 rocket in February after two failed attempts early this year.

The rocket, billed as a flexible and cost-effective new flagship, is scheduled to lift off between 9:22 am and 1:06 pm (0022 and 406 GMT) on February 15 from the southern island of Tanegashima, the Japan Aerospace Exploration Agency (JAXA) said in a press release.

The third launch attempt comes after the spacecraft was forced to self-destruct in March when the command center concluded its mission could not succeed.

CRISPR had a huge year. Even better, it’s still a work in progress, with the potential to reshape biotechnology for decades to come.

Scientists looking to tackle our ongoing obesity crisis have made an important discovery: Intermittent fasting leads to significant changes both in the gut and the brain, which may open up new options for maintaining a healthy weight.

Researchers from China studied 25 volunteers classed as obese over a period of 62 days, during which they took part in an intermittent energy restriction (IER) program – a regime that involves careful control of calorie intake and fasting on some days.

Not only did the participants in the study lose weight – 7.6 kilograms (16.8 pounds) or 7.8 percent of their body weight on average – there was also evidence of shifts in the activity of obesity-related regions of the brain, and in the make-up of gut bacteria.
