Meteorite blasts ‘largest new crater’ NASA has ever seen on Mars
A recent meteorite impact on Mars was so powerful it could be felt by a NASA lander thousands of miles away – and the new Martian crater it created could affect our…
‘Planet-killer’ asteroid with potential to collide with Earth found lurking in sun’s glare
For a long time, the shard of the sun hid a secret – a trio of space rocks with a member that could one day be dangerous for the planet. Of the…
How to detect a human-made biological threat
A new, very transmissible strain of influenza emerges. A pesticide-resistant insect is decimating huge areas of crops. A patient ends up in the emergency room with a bacterial strain that does not…
New evidence for liquid water on Mars
The study also suggests that Mars is geothermally active. Previous research has suggested that there is water under Mars’ south polar ice cap. New evidence from an international research team suggests there…
The Royal Society of Chemistry will make all its journals open access
The Royal Society of Chemistry (RSC) is committed to making all of its journals open access within the next five years. It is the first chemistry publisher to commit to a 100%…
Space is increasingly dangerous – here’s how NASA avoids deadly debris
About once per year, the International Space Station takes evasive action to avoid colliding with a piece of space debris. The most recent maneuver took place last week when the ISS boosted…
Perovskite-silicon tandem solar cells enhanced by nano-optics
Tandem perovskite-on-silicon photovoltaic cells have the potential to outperform standard silicon (Si)-based photovoltaic cells in terms of power conversion efficiency (PCE). Study: Nano-optical designs for high-efficiency monolithic perovskite-silicon tandem solar cells. Image…
Radioactive traces in tree rings reveal Earth’s history of ‘radiation storms’
Searching for planets and studying their stars, I have had the privilege of using some of the largest telescopes in the world. However, our team recently turned to an even larger system…
Antibiotic resistance linked to these household products
Chemicals such as triclosan enter sewage treatment plants after being flushed into our sewers. There they can interact with bacteria and cause the development of antibiotic resistance. Credit: About. Science. Technology. 2022…
