We live on a moving target in a cosmic firing range. Each day, the Earth is bombarded by about a hundred tonnes of space debris. It may sound alarming, but this is really nothing to worry about. Most of the objects that fall towards our planet are pretty small – typically about the size of a grain of sand or even smaller – and burn up in the upper atmosphere tens of kilometres above the ground.
An international team of astronomers has uncovered the remains of an ancient collection of stars pulled apart by the Milky Way more than two billion years ago.
The potential applications of bio-inks are countless. They range from converting 2D cell cultures in Petri dishes to more realistic 3D cultures, repairing or replacing damaged cells or tissues due to illness or injury, and growing 'mini organs-on-chip' to screen for new medicines.
The brain has always been a fascinating subject to scientists, as countless studies are done each year. However, how the brain works exactly mostly remains a mystery to this day. In this article professor of electrical engineering and bioengineering, Salvatore Domenic Morgera explains his insights and views on one particular conundrum within the enigma that is our brain, namely the relationship between the brain’s physical structure and its functionality.
An international team of astronomers shot the very first direct-image of a young, sun-like star accompanied by two giant exoplanets.
Scientists took a look at the physical and mathematical mechanisms behind the gorgeous phenomenon of bioluminescence created by single-celled organisms.

Findings might help uncover more about our Moon's mysterious origin story.
Nuclear waste is something that speaks to the imagination of many and there are a lot of persistent myths and misconceptions. Here are four things you didn’t know about nuclear waste
Up until now, astronomers have mainly looked at fairly mature protoplanetary disks around young stars that are 1 to 3 million years old, it turns out that planet formation starts much earlier.
Viruses challenge our concept of what 'alive' even means
Antibiotic-resistant super bacteria form a severe threat to our health system. Researchers from Ghent University (UGent) and KU Leuven presented a new platform that will put the search for alternatives to antibiotics in a higher gear
Scientists finally solved the long-lasting mystery of the missing ordinary matter of the cosmos.
In recent years, UV filters components derived from sunscreen have been detected more frequently in coastal waters. These UV filters seem to weaken coral, causing the warmed seawater to damage the coral further.
Scientists from various universities were able to set an eye-wateringly fast record of squeezing 44.2 terabits per second of data through an existing fiber optic cable. This new world record was achieved by using a so-called 'micro-comb,' which is capable of firing several laser beams in a bundle.
In our search for extraterrestrial life, we tend to look at ‘conventional’ Earth-Like exoplanets, searching for atmospheres for recognizable bio-signatures. This makes sense, after all, we only have one sample of a life hosting planet in the universe. Still, it could be smart to also look at different indicators, as alien life might use dissimilar chemistry to our own. In a new study, scientists argue to broaden our search. Professor of Planetary Geosciences, David Rothery, explores the…
Plants are capable of registering essential information about environmental conditions. Scientists are finding out how they delete this memory after they produced seeds.
Scientists wanted to be able to see what cells and diseases are doing inside our body on a cellular level, in real-time. A group of researchers developed a groundbreaking microscope to do this.
Fomalhaut b, an exoplanet located only 25 lightyears from Earth in the constellation Piscis Australis, apparently disappeared from sight when astronomers recently tried to observe it using the Hubble Space Telescope. Its disappearance has scientists baffled while they look for an explanation.
As time progresses, we are slowly getting to know the coronavirus (SARS-CoV-2) better. We know, for example, that the virus can remain stable on surfaces like plastic and steel for up to three days and that it is detectable in aerosols for up to 3 hours. We've also discovered that animals like tigers can get the coronavirus. But what about our pets? Can they get COVID-19? And can they transfer the disease to their owners? In this article, Annette O'Connor, Jan Sargeant, and Sarah Totton…
The weather might seem like it creates weeks of dreary, grey drizzle. But it can also put on a truly sensational – and, often, deadly – show. But what explains these explosive events?
Selenium might help in treating the coronavirus disease in the future. In Western Europe, selenium deficiencies have been diagnosed in the elderly, obese, and those with weakened immune systems. Researchers want to know whether these deficiencies influence the course of COVID-19
The planet was hidden in early data from the Kepler space telescope.
