Cell ‘bones’ mystery solved with supercomputers

Thin, flexible protein strands called actin filaments act like bones for our cells and are critical for its movement. Supercomputer simulations have helped solve a decades-old mystery of how actin filaments polymerize, or chain together.

Dinosaur embryo find helps crack baby tyrannosaur mystery — ScienceDaily

They are among the largest predators ever to walk the Earth, but experts have discovered that some baby tyrannosaurs were only the size of a Border Collie dog when they took their first steps. The first-known fossils of tyrannosaur embryos have shed light on the early development of the colossal animals, which could grow to […]

Scientists solve a 100-year-old mystery about cancer — ScienceDaily

The year 2021 marks the 100th anniversary of a fundamental discovery that’s taught in every biochemistry textbook. In 1921, German physician Otto Warburg observed that cancer cells harvest energy from glucose sugar in a strangely inefficient manner: rather than “burn” it using oxygen, cancer cells do what yeast do — they ferment it. This oxygen-independent […]

Mystery particle may explain extreme X-rays shooting from the ‘Magnificent 7’ stars

More than 400 light-years from Earth, there is a cluster of young neutron stars that are too hot for their age. These stars, known as the “Magnificent Seven,” emit a stream of ultra-high-energy X-rays that scientists haven’t been able to explain.  Now, scientists have proposed a possible culprit: axions, theoretical particles that turn into light […]

Mystery of massive, train-stopping millipede swarms solved

For over a century, thousands of poisonous millipedes have swarmed train tracks in the thick, forested mountains of Japan, forcing trains to grind to a halt. These “train millipedes,” so-called for their famous obstructions, would appear every so often — and then disappear again for years at a time. Now, scientists have figured out why. […]

Unravelling the mystery that makes viruses infectious — ScienceDaily

Researchers have for the first time identified the way viruses like the poliovirus and the common cold virus ‘package up’ their genetic code, allowing them to infect cells. The findings, published today (Friday, 8 January) in the journal PLOS Pathogens by a team from the Universities of Leeds and York, open up the possibility that […]

The new COVID-19 variants are still a mystery, but here’s what we know so far

Viruses mutate a lot, and SARS-CoV-2 is no exception. (NIAID-RML/) If there’s one thing we can count on in life, it’s change, and viruses are no exception. Variants of the original SARS-CoV-2 virus have popped up in different corners of the world and while that might sound a bit scary it’s actually perfectly normal, or […]

Discovery of chemical clue may lead to solving cacao’s black pod rot mystery
