Dodgy internet connection? Here’s what might be behind it

Tero Vesalainen/Shutterstock For most people, diagnosing a dodgy internet connection is nigh on impossible. After all, the internet is a complex hodgepodge of hardware and software, and the odd jumpy Zoom call is often accepted as an inexplicable feature of a network we don’t well understand. But internet connection issues…

Origin of Life: Lightning Strikes May Have Provided Missing Ingredient for Earth’s First Organisms

Origin of Life: Lightning Strikes May Have Provided Missing Ingredient for Earth’s First Organisms The origin of life on Earth is one of the most complex puzzles facing scientists. It involves not only identifying the numerous chemical reactions that must take place to create a replicating organism, but also finding…

Origin of life: lightning strikes may have provided missing ingredient for Earth’s first organisms

Lightning on early Earth. Lucy Entwisle, Author provided The origin of life on Earth is one of the most complex puzzles facing scientists. It involves not only identifying the numerous chemical reactions that must take place to create a replicating organism, but also finding realistic sources for the ingredients needed…

We grew human tear glands in the lab, and now we’re making them cry

Most organs in the adult human body are capable of regeneration, which means they renew their cells to keep the tissue healthy and functional. This capacity is enabled by adult stem cells, which are present in most organs and divide to create new cells that replace older, damaged ones. It…

Astronauts on Mars missions could suffer cognitive and emotional problems – new research

The brain is deeply affected by the change of gravity. Gorodenkoff/Shutterstock Human space missions to Mars are the next great leap in space exploration, with Nasa targeting the 2030s as a reasonable time frame for taking the first humans there. But boarding on a journey to Mars is not like…

Evolution: Why It Seems to Have a Direction and What to Expect Next

Evolution: Why It Seems to Have a Direction and What to Expect Next The diversity and complexity of life on Earth is astonishing: 8 million or more living species—from algae to elephants—all evolved from a simple, single-celled common ancestor around 3.5 billion years ago. But does that mean that evolution…

Scientists 3D Printed Ears Inside Living Mice Using Light

Scientists 3D Printed Ears Inside Living Mice Using Light Tissue engineering just got wilder and weirder. Using nothing but light and bioink, scientists were able to directly print a human ear-like structure under the skin of mice. The team used a healthy ear as a template and 3D printed a…

Titanic salvage: recovering the ship’s radio could signal a disaster for underwater cultural heritage

NOAA/Institute for Exploration/University of Rhode Island The RMS Titanic’s Marconi radio was last used to make distress calls from the north Atlantic after the ship struck an iceberg on April 14 1912. Now it could become the target of a salvage operation after a private company was granted permission to…

Three New Views of Mars' Moon Phobos

Taken with the infrared camera on NASA’s Odyssey orbiter, the images reveal temperature variations aboard the small moon as it drifts into and out of Mars’ shadow. Three New Views of Mars' Moon Phobos

Computing Power Can Keep Growing as Moore’s Law Winds Down. Here’s How

Computing Power Can Keep Growing as Moore’s Law Winds Down. Here’s How Moore’s Law is faltering, but that doesn’t mean the end of progress in processing power. Rather than relying on semiconductor physics and silicon-fabrication technology, though, we need to turn to innovations in software, algorithms, and hardware, says a…

Are viruses alive? Perhaps we’re asking the wrong question

Axel_Kock/Shutterstock Viruses are an inescapable part of life, especially in a global viral pandemic. Yet ask a roomful of scientists if viruses are alive and you’ll get a very mixed response. The truth is, we don’t fully understand viruses, and we’re still trying to understand life. Some properties of living…
