It is an often heard complaint from smartphone, tablet and laptop users. As your device gets older it seems that you can do less and less on a single charge.

A potentially new type of synthetic crystal based solar cells could leas to cheaper and more efficient solar panels.

There have been plenty of claims about what being left-handed means, and whether it changes the type of person someone is – but the truth is something of an enigma. Myths about handedness appear year after year, but researchers have yet to uncover all of what it means to be left-handed.

There are few places in the Solar System which are as fascinating as Saturn’s moon Titan. It’s a world with a thicker atmosphere than Earth. Where it’s so cold that it rains ammonia, forming lakes, rivers and seas. Where water ice forms mountains. 

As NASA prepares to return to the Moon by 2024 as part of its Artemis program, the agency is focusing its efforts on exploring the Moon’s polar regions. These are areas of the Moon which seem to have a lot of water mixed in with the regolith.

Researchers found that people who ate high levels of vitamin A were 17 percent less likely to get the second-most-common type of skin cancer years later.

In new research led by the University of Warwick, scientists have determined the best candidate remnant stars to search for relics of planets, based upon the likelihood of the stars hosting surviving planetary cores and the strength of the radio signal that we can tune in to.

New class of materials could enhance supercapacitors and increase their and make them less flammable. In addition if used to supplement battery systems in EV’s they could provide a power boost

Many dream of what they would do had they a time machine. Some would travel 100 million years back in time, when dinosaurs roamed the Earth. Not many, though, would think of taking a telescope with them, and if, having done so, observe Saturn and its rings.

How common is Earth?

Even though the black hole at the center of the Milky Way is a monster, it’s still rather quiet. Called Sagittarius A*, it’s about 4.6 million times more massive than our Sun. Usually, it’s a brooding behemoth. But scientists observing Sgr. A* with the Keck Telescope just watched as its brightness bloomed to over 75 times normal for a few hours.

Global climate change is endangering small island countries, many of them developing nations, potentially harming their ability to function as independent states.

Indian tiger numbers are up, according to one of the most detailed wildlife surveys ever conducted. Tiger populations have risen by 6%, to roughly 3,000 animals.

Some might balk at the idea that plants made of roots, stems and leaves could have intelligence or consciousness. But scientists have actually been hotly debating this idea for decades.

Overindulgent interaction with electronic devices like smartphones and tablets may be related to weaker activity in areas of the brain that are key to understanding scientific texts, say researchers.

Despite all we know about the formation and evolution of the Universe, the very early days are still kind of mysterious. With our knowledge of physics we can shed some light on the nature of the earliest stars, even though they’re almost certainly long gone.

For decades, astronomers have been trying to see as far as they can into the deep Universe. By observing the cosmos as it was shortly after the Big Bang, astrophysicists and cosmologists hope to learn all they can about the early formation of the Universe and its subsequent evolution. Thanks to instruments like the Hubble Space Telescope, astronomers have been able to see parts of the Universe that were previously inaccessible.

By creating millions of virtual universes and comparing them to observations of actual galaxies, a University of Arizona-led research team has made discoveries that present a powerful new approach for studying galaxy formation.

What if you didn’t need surgery to implant a pacemaker on a faulty heart? What if you could control your blood sugar levels without an injection of insulin, or mitigate the onset of a seizure without even pushing a button?

Astronomers have discovered evidence for the farthest "cloaked" black hole found to date

Since the “Golden Age of General Relativity” in the 1960s, scientists have held that much of the Universe consists of a mysterious invisible mass known as “Dark Matter“. Since then, scientists have attempted to resolve this mystery with a double-pronged approach. On the one hand, astrophysicists have attempted to find a candidate particle that could account for this mass.

The 17th-century astronomer Johannes Kepler was the first to muse about the structure of snowflakes. Why are they so symmetrical? How does one side know how long the opposite side has grown? Kepler thought it was all down to what we would now call a “morphogenic field” – that things want to have the form they have. Science has since discounted this idea. But the question of why snowflakes and similar structures are so symmetrical is nevertheless not entirely understood.

An Israeli spacecraft called Beresheet almost made it to the moon in April. It took a selfie with the lunar surface in the background, but then lost contact with Earth and presumably crashed onto the lunar surface. Now it’s been revealed that the mission was carrying a cargo of dehydrated microscopic lifeforms known as tardigrades.

The question of how life on Earth first emerged is one that humans have been asking themselves since time immemorial. While scientists are relatively confident about when it happened, there has been no definitive answer as to why it did. How did amino acids, the chemical building blocks of life, come together roughly four billion years ago to create the first protein molecules?

There are about 22,000 large objects orbiting the Earth, including working and broken satellites and bits of old rocket from past space expeditions. If you include all the equipment dropped by astronauts while floating in space and the debris from colliding satellites down to around 1 centimeter in size, there are about one million bits of space junk in Earth’s orbit.

Despite a few setbacks in the past few months, 2019 is shaping up to be an exciting year for SpaceX

Personalized nutrition, where your DNA tells you what to eat and what not to eat, is gaining momentum. And for those with money to spare, a number of companies now offer fully personalized nutritional advice aimed at improving your overall health.

A new method could get graphene a step closer to replacing less-effective copper interconnects in the world’s computer devices.

The entire Apollo 11 mission to the moon took just eight days. If we ever want to build permanent bases on the moon, or perhaps even Mars or beyond, then future astronauts will have to spend many more days, months and maybe even years in space without a constant lifeline to Earth. The question is how would they get hold of everything they needed. Using rockets to send all the equipment and supplies for building and maintaining long-term settlements on the moon would be hugely expensive.

As you may know, hot air rises. So why is it so cold at the top of a mountain?
