Researchers analysed data of hundreds of UK children who had been born through IVF or ICSI (when the man has a low sperm count), testing the same groups of children every few years up to the age of 11. They found a positive association between artificial conception and cognitive development when a child was between the ages of three and five.

Both the literature and practice indicate that children can stand without support starting at around 9 months old. Yet, with practice, children can stand without support even before they are 4 months old. This is much earlier than has been reported in the literature.

By developing a way to tune the color of individual pixels, researchers have eliminated the need for subpixels -- allowing a greater density of pixels and much higher resolution for video displays.

A new study highlights novel approaches to tackling deforestation. The team focused their research on Borneo, an island that has lost a staggering 30 percent of its forest since the 1970s and is among the most biodiverse and threatened on the planet. The loss of Bornean forests threatens species such as the orangutan, Sumatran rhino, and the Sunda clouded leopard; as well as emitting significant amounts of carbon dioxide into the atmosphere.

The virus that causes chickenpox -- varicella zoster virus (VZV) -- possesses a protein that could enhance its ability to hijack white blood cells and spread throughout the body, according to new research.

Researchers have identified a new way to potentially slow the fast-growing cells that characterize all types of cancer. By removing a specific protein from cells, they were able to slow the cell cycle, which is out of control in cancer. The findings were made in kidney and cervical cancer cells and are a long way from being applied in people, but could be the basis of a treatment option in the future.

The US Nuclear Regulatory Commission relied on faulty analysis to justify its refusal to adopt a critical measure for protecting Americans from nuclear-waste fires at dozens of reactor sites around the country, according to a recent article. Radioactivity from such a fire could force approximately 8 million people to relocate and result in $2 trillion in damages.

NASA's Juno mission is rewriting what scientists thought they knew about Jupiter specifically, and gas giants in general, according to a pair of Science papers released today. The Juno spacecraft has been in orbit around Jupiter since July 2016, passing within 3,000 miles of the equatorial cloudtops.

For the first time in history, astronomers have been able to watch as a dying star was reborn as a black hole. It went out with a whimper instead of a bang.

It's hard to imagine that the Solar System's biggest planet, which provided Galileo with his first key astronomic observations, has a lot of secrets left 450 years later. Yet, despite countless hours spent peering through telescopes and numerous robotic visitors, there's a lot we still don't know about Jupiter. Most notably, we didn't even have a decent picture of the planet's poles, and we have little idea of what its interior might look like.

Thanks to the arrival of the Juno probe, however, that's starting to change. After just a few orbits, Juno has imaged both poles, tracked some of the dynamics of its atmosphere, and started providing evidence of what may lie at the crushing depths of the planet's interior.

Staring at the clouds

Earlier this year, Juno performed the closest approach to Jupiter ever made by human hardware, passing within 5,000km of Jupiter's cloud tops. Juno's highly elliptical orbit also takes it over both poles, allowing them to be imaged in greater detail than ever before. And every instrument on the probe managed to capture some data.

A new species of a fossil pliosaur (large predatory marine reptile from the 'age of dinosaur') has been found in Russia and profoundly change how we understand the evolution of the group, says an international team of scientists.

A new study reveals the science behind a 'trick of the light' that made high-profile photographs of a major piece of public art appear 'faked' despite the pictures being entirely genuine. Vision science researchers found images of the 75-meter long wind turbine appeared super-imposed because of a visual illusion caused by light reflections playing on preconceived notions about how objects are lit in natural settings, altering the object's shape to the human eye.

If you ever fly from L.A. to San Francisco, California, you may notice the Gabilan Mesa off to the east as you begin your descent into San Francisco International Airport. If you look carefully, you might notice two strange things: a series of bleach-white scars, where rock outcrops disrupt the smooth, grassy hillslopes, and a strong asymmetry in the orientation of tributaries, with many flowing south and few flowing north.
