Could Mars once have supported life?

NASA’s Curiosity rover has collected data from Mars that scientists are interpreting as indicating that the red planet once had an oxygen-rich atmosphere.

James Webb telescope set to replace Hubble

NASA has revealed details of the main mirror of the James Webb Space Telescope. The telescope is set to be launched in 2018 and it will be bigger and more powerful than Hubble.

New model for predicting Zika virus infection rates

Zika virus disease is easily transmitted. However, in the majority of people the disease is asymptomatic — symptoms appear in only one in four people, mostly as a mild fever. To find out why, a new study has been running.

Essential Science: Are parasitic worms good for the gut?

Horrible as it may seem, there are biological advantages to having parasitic worms in terms of warding off various diseases. This is because parasites trigger an immune reaction that calms inflammation. The benefit has been explored in a new study.

German scientists seek way to end live chick shredding

In a basement of Dresden University, German scientists are busy refining a technique that could save millions of fluffy chicks from being shredded to death moments after they hatch.

Will leaving the EU affect British science?

The U.K. referendum taking place in June on whether to leave the European Union is being discussed on many levels, from economic to nationalistic. Recently it was the turn of science: will British science be better or worse in or out?

HIV causes premature ageing by 5 years

New research into the Human Immunodeficiency Virus (HIV) has discovered that an infection with the virus causes a person to prematurely age. The total effect is that ageing accelerates by around five years.

Solar Impulse 2, an experimental plane flying around the world without consuming a drop of fuel, has landed in California, one leg closer to completing its trailblazing trip."The Pacific is done, my friend.

Science and technology will make it possible to garden on Mars

An aerospace engineering student at the University of Colorado, Boulder has been making the stuff of science-fiction into reality, inventing two robots that can grow fruits and vegetables as well as monitor human health in space.

Is CRISPR technology set to change biological science?

Gene editing technology is seemingly the most important scientific method to emerge in recent years. The primary method is called CRISPR and it is transforming the field of biology.

Seeds may have helped birds survive extinction of the dinosaurs

While there's plenty of evidence to suggest that dinosaurs were already in decline millions of years before the asteroid impact that spelled their doom, we know that those small, feathered theropod dinosaurs, otherwise known as birds, did survive.

Blocks showing Queen Hatshepsut as a woman unearthed

Ancient Egypt was a male-dominated world ruled by men, so much so that very few women ever rose to power. One such woman, Hatshepsut, was able to commandeer the throne of Egypt, and in the latter part of her reign, ruled as a man.

Using nanoparticles to block asthma
