This week we take a closer look at the “Great Wall of Mongolia”, the quest for better energy storage takes a leap forward in the form of time-bending quantum batteries, and a 150-year-old pliosaur skull is examined by Sir David Attenborough as part of a new series for the BBC. Finally, we take a look at why your muscles hurt quite so much after the workout you did three days ago.

Unexpected New COVID Symptoms Arise As JN.1 Variant Continues To Spread
The JN.1 COVID variant had a rapid spread throughout December 2023 and has now become the most common strain of the virus spreading across the US, according to the US Centers for Disease Control and Prevention (CDC). Cases of JN.1 are also creeping up in the UK, as well as China and India. Read the full story here.
OSIRIS Mission Sets Sights On "God Of Destruction" Asteroid At Crucial Time
As NASA struggles to access the treasure obtained by the OSIRIS-REx mission to Bennu, it has also had to decide what to do with the valuable and still-operating spacecraft responsible. Now that decision has been made, confirming a long-standing plan, with the target set for an even more-famous Earth-crossing asteroid, 99942 Apophis, and a tweak to the mission name.

Mysterious 405-Kilometer-Long "Great Wall Of Mongolia" Studied For First Time
A section of the Great Wall of China that extends into Mongolia has been analyzed for the first time, allowing researchers to present some speculative insights into the history and function of this enormous structure. Spread over 405 kilometers (252 miles), the wall has been dubbed the "Mongolian Arc" due to its curved trajectory. Read the full story here.
Time-Bending Quantum Batteries Could Surpass Chemical Versions For Energy Storage
Batteries that make use of quantum phenomena that appear to mock our conventional understanding of the laws of physics could be harnessed for energy storage. Although these batteries have only been produced on a small scale in laboratories, one day they might offer advantages over conventional batteries that could see them be the preferred choice in at least some niches.

Pliosaur Skull Dating Back 150 Million Years May Be A New-To-Science Species
The enormous teeth of a “giant sea monster” were restored by fossil expert Chris Moore after he and Steve Etches endured the painstaking task of removing a huge fossil skull 12 meters (39 feet) up a cliff in Dorset, UK. It belonged to a pliosaur, an ancient marine reptile with a bite force that could’ve bested Tyrannosaurus rex in a fight, according to scientists working on the discovery. Read the full story here.

Why Do Your Muscles Start To Ache Days After Working Out?
Exercise can be amazing for you: regularly getting active can reduce your risk of a whole host of ailments, such as heart attacks and strokes, and simply getting out for a walk can reduce your risk of death. Indeed, the World Health Organization states that those who don’t work out enough have a 20-30 percent increased chance of death. But if exercise is so good for you, why can it hurt so much – and why can the pain commence days after you’ve staggered out of the gym? Read the full story here.
