For the first time, scientists have shown that it’s possible for two people of the same sex to create a baby, without the need for outside egg or sperm donation. The most obvious benefits would be for homosexual couples who want to have a child together, but the method could also help couples who have been affected by infertility.
The origin of life on Earth is a set of paradoxes. In order for life to have gotten started, there must have been a genetic molecule—something like DNA or RNA—capable of passing along blueprints for making proteins, the workhorse molecules of life. But modern cells can’t copy DNA and RNA without the help of proteins themselves. To make matters more vexing, none of these molecules can do their jobs without fatty lipids, which provide the membranes that cells need to hold their contents inside.
Scientists have discovered evidence of oxygen-breathing microbial life more than 200 feet below the ocean floor—or 12,000 feet below sea level in the Pacific Ocean.
A team led by astronomers from the Jagiellonian University in Krakow, Poland, recently used the W. M. Keck Observatory in Hawaii to observe and measure a rare class of "active asteroids" that spontaneously emit dust and have been confounding scientists for years. The team was able to measure the rotational speed of one of these objects, suggesting the asteroid spun so fast it burst, ejecting dust and newly discovered fragments in a trail behind it.

Two new maps of Mercury taken by a NASA probe have identified never-before-seen formations on the planet's surface.
NASA’s Jet Propulsion Laboratory recently announced that it is developing a small drone helicopter to scout the way for future Mars rovers. Why would Mars rovers need such a robotic guide? The answer is that driving on Mars is really hard.
A fatty acid might be among organic molecules discovered on Mars by Nasa's Curiosity rover.
Stone tools that are half a million years old have been unearthed in Israel — and they still have traces of elephant fat clinging to them.
Some 19,000 years ago, a woman was coated in red ochre and buried in a cave in northern Spain. What do her remains say about Paleolithic life in western Europe?
Once upon a time, 4,000 to 8,000 years after humanity invented agriculture, something very strange happened to human reproduction. Across the globe, for every 17 women who were reproducing, passing on genes that are still around today—only one man did the same.
Earth is now entering a period of changing climate that will likely be faster than what's occurred naturally over the last thousand years, according to a new article, committing people to live through and adapt to a warming world.
Spring arrives on Friday, and you might want to make the most of it. The season of flowers and showers actually gets shorter every year by about 30 seconds to a minute, due to astronomical quirks, researchers say.
Phytomining is a method for literally ‘farming’ metals by growing hyperaccumulator plants and then harvesting the biomass rich in a particular metal. The potential for phytomining is greatest for nickel because of the occurrence of vast areas of ultramafic soils that are naturally enriched in nickel and occur around the world, and also because there are a number of potentially suitable hyperaccumulator species to be used as ‘metal crops’.

When it comes to the future of farming, could sun and dirt become a thing of the past?

Did you know that there are mushrooms that actually glow? Aristotle was aware of this intriguing fact more than 2,000 years ago. He also was the first person to ask a simple question in print: Why? Now, researchers reporting in the Cell Press journal Current Biology on March 19 finally have a good answer. The light emitted from those fungi attracts the attention of insects, including beetles, flies, wasps, and ants. Those insect visitors are apparently good for the fungi because they spread the fungal spores around.

The human eye is optimised to have good colour vision at day and high sensitivity at night. But until recently it seemed as if the cells in the retina were wired the wrong way round, with light travelling through a mass of neurons before it reaches the light-detecting rod and cone cells. New research presented at a meeting of the American Physical Society has uncovered a remarkable vision-enhancing function for this puzzling structure.
Short-sightedness is reaching epidemic proportions. Some scientists think they have found a reason why.
