Why one pole is melting, while the other is still packed with ice

In the past decade, ice extent at the two poles couldn't be more different. The Arctic has seen its 13 smallest maximum ice extents in the last 13 years, and since 1979 lost 620,000 square miles of winter sea ice cover, an area more than twice the size of Texas. Meanwhile, in Antarctica, ice cover has actually increased despite warming trends

Artificial meteor shower might open the Japan 2020 Olympic Games

Man 3-D prints his wife's tumor and saves her life

ZME Science has reported extensively on how 3-D printing is being implemented in the medical sector with some fantastic results. Yet, the real revolutionary thing about 3D printing – whether used for product prototyping, printing prostheses or spare parts on the International Space Station – is that anyone can use it. Such is the story […]

Do trees sleep, too?

All living things, from polar bears to bacteria, become more active or slow down their metabolism over a 24-hour cycle. Why should trees, which are just as alive as we are, be exempted from this rule?

Flying quarter-sized RoboBee perches to save energy

Two new exotic-looking triceratops relatives found in Utah and Montana

Paleontologists have discovered two new triceratops relatives that simply looked amazing. One had two forward-curving spikes running from the back of its shield, in addition to the classic triceratops horns, while the other sported beautiful coloring akin to butterfly camouflage, but also a tragic life story.

Why giraffes have long necks: first genome sequencing offers some clues

Researchers have sequenced the genomes of the tallest mammal on Earth, as well as it's unlikely closest cousin, the okapi. By comparing the genomes of the two species, we now have a firmer grasp of the evolutionary timeline in which the split from a common ancestor took place.

Can science help LSD make a comeback?

Few drugs have had a more undeserving bad rep as LSD, but acid is finally making a comeback, it seems.

A.I. masters control of delicate Nobel-winning physics experiment in under an hour

Lazy physicists from Australia programmed an artificial intelligence system to maneuver a delicate experiment with little to no oversight. The A.I. had to control an array of lasers that are used to cool atoms near absolute zero temperature, where the slightest hiccup could destroy the fragile state of matter of the atoms. But the machine performed marvelously.

Spider silk-inspired wire extends like a solid, but compresses like a liquid

. Perhaps the most impressive feature of spider silk is that it's taut even when it's been stretched to several times its original size. Inspired by the orb spider's silk, researchers at University of Oxford and the Université Pierre et Marie Curie, Paris made their own artificial spider silk thread that extends like a solid, but compresses like a liquid.

IBM ups storage for next-gen memories hundreds of times faster than your SSD

A team from IBM Research dramatically increased the storage capacity of an alternative memory structure called phase-change memory (PCM) to 3 bits of data per cell. Many specialists think that PCM is the future, in a way similar to how flash is replacing hard drives.

This machine 3-D prints metal objects in mid-air

Harvard researchers have demonstrated an all new 3-D printing technique that creates metals objects with complex shapes right in mid-air. This is fundamentally different from the approach of traditional 3-D printers which ooze polymer material layer by layer.

Ancient Rome's water supply tracked by lead isotopes

By analyzing telltale chemical signs which marked the environment, like led isotopes, a team of researchers tracked the water quality following the eruption of Vesuvius in AD 79.

Bone-crushing dog roamed eastern North America 12 million years ago

Paleontologists have identified an ancient hyena-like canine that occupied eastern North America approximately 12 million years ago. The coyote-sized dog had a massive jaw which scientists say it used to crush bones.

Google's AI is now writing post-modern poetry. I've read worse

Despite these tentative first steps definitely look like a work in progress, don't look so stunned when you'll learn about the first best-selling novel written by a robot (I've seen worse things published). It all starts now.

This transparent wood is stronger than glass

Using a chemical technique, researchers removed the complex organic polymers that give wood its characteristic appearance and, in the process, made the wood transparent. The see-through wood was then imbued with epoxy which made the material stronger than glass.

Man receives first penis transplant in the United States

A man recovering from penile cancer is the first American citizen to receive a penis transplant. The operation, a first in the United States, was performed by doctors at the at Massachusetts General Hospital in Boston. According to the doctors involved, more transplants will occur in the coming years. This is still, however, an experimental procedure at the forefront of medicine.

Newly discovered beetle births live babies

In almost all mammals, the babies develop inside the mother before they are born, a process we all know as gestation. Outside mammals, though, live baby birth is quite rare, especially among insects. That's why everybody got excited by the discovery of a new long-horn beetle species which uses ovoviviparity -- a reproductory mode in which females hatch eggs inside the body.

Is the ultimate password 'chill' music?

We've gone a long way since simple keys and locks. Things like digital encryption or biometric validation methods based on fingerprints, corneas and so on have helped secure data and access to sensible information.These methods were developed, however, because we had to keep up with the threats. There's nothing truly unhackable, some say, but you can darn well make it really hard for the wrong people to get in. These researchers really thought outside the box, though.

Tesla's first self-driving accident just happened. It's time to start a serious discussion

It was bound to happen. This week, Jared Overton, a Tesla Motors Model S owner, reported his car spontaneously started itself and drove into a trailer parked right in front of it. No one was hurt, but the car itself broke the windshield. Tesla Motors claims their software wasn't to blame. Instead, internal logs suggest Overton used the 'summon' feature by mistake from his phone. Overton disagrees. It seems like a lawsuit might follow, but the accident begs a more important discussion: are Tesla's autonomous features really safe?

Bacterial cells are individualists, too

Even though they're genetically identical and live in the same environment, not all bacteria are the same. When times are tough more bacteria become individualists gobbling resources in the detriment of the colony, but in doing so the individualists actually enhance the colony's survival rate.

Oldest space dust shows how Earth's ancient atmosphere was like 2.7 billion years ago

A team from Monash University, Australia, and Imperial College, U.K., found the oldest micrometeorites ever and by studying them could determine what the planet's atmosphere looked like 2.7 billion years ago when these objects impacted the surface.

THC blood tests can't predict impaired driving and should be scrapped, AAA says

The AAA Foundation for traffic safety ordered a handful of studies that assess the effects marijuana legalization had on driving safety. The studies arrived at a number of worrisome conclusions. Fatal crashes involving drivers who used marijuana doubled since the state lifted the ban. Also, researchers found the marijuana blood limit allowed for driving, known as per se limits, is arbitrary and not based on actual science.

Germany generated so much renewable energy it had to pay to get rid of it

On May 8, Germany generated a record high amount of renewable energy. Solar, wind, hydro and biomass plants together generated 55 GW of power or 87% of the demand thanks to unusually good winds and sunny conditions.

Half of your friends don't actually feel the same way, probably

How many friends do you think you have? A hundred, twenty... two? Chances have it, you actually have only half as many 'real' friends as you think. At least, those who look to you as a friend too, say researchers at MIT's Media Lab.

Carrot genome explains why these are orange

Carrots are the richest source of vitamin A in the American diet, which is why you hear "they're good for your eyes". But did you know carrots were initially yellow and purple? Even further back, before humans domesticated carrots, the wild variety was white. Scientists know this by sequencing the DNA of the carrot, and a recent study deciphered its full genetic code. We now know what genes trigger the production of carrots' most important nutrients, but also what teaking is required to improve the crops.

What separates the wolves from the sheep in the stock market?

"Be fearful when others are greedy and be greedy only when others are fearful," said Warren Buffet, arguably the most astute contemporary investor in the world. Research by Caltech and Virginia Tech backs this sound advice, after delving deep into the investor mind and framework by analyzing stock market behavior at the neurolevel.

The squishy bot revolution: how soft robotics is changing the field

Soft robotics involves machines designed to resemble biological systems like squids, caterpillars, starfish, human hands and more. Though far less practical at this point, soft robots could prove invaluable soon enough. ZME Science looked at a couple of some of the most amazing designs made by scientists so far.

How trade routes forever changed the dromedary camel's genetic makeup

Known as the “ship of the desert”, the dromedary camel is one of the largest domestic ungulates and one of the most recent additions to livestock. For 3,000 years, the dromedary camel has been the burden animal of choice for transporting goods across the deserts of North Africa and the Arabian Peninsula, and all of this back and forth has left a permanent mark on their genetic makeup.

How many people are younger or older than me?

The Pentagon is investing heavily to protect its 'space real estate'

Both civilian and military applications have become heavily reliant on digital communications, which in turn are dependent on space hardware like satellites. If only two decades ago, only the biggest companies or wealthy governments could afford to launch permanent or semi-permanent satellites. Today, satellites are smaller, better and cheaper than they ever were, which is why there are more than 1,100 active satellites orbiting the planet. However, they're as vulnerable as ever, too.

'Second skin' hides signs of aging, while also improving skin health

Developed by researchers at MIT for over a decade, the 'second skin' is a transparent, silicone-based polymer that can be layered over the human skin. Flexible and strong, the novel material can return to its original size after being stretched to over 250%, which is actually better than human skin which can only stretch to 180%.

British energy expert: 'oil companies have 10 years to change strategy or die'

One energy expert from the U.K. made headlines with his bold comments. He says oil companies have only 10 years to adapt and make a shift away from fossil fuels -- their primary business, after all -- otherwise these will collapse. The market will not be forgiving.

Novices learn faster after being zapped with expert brain wave patterns

In the movie, The Matrix, Neo masters over a dozen martial arts in a fraction of a second as the necessary skills are uploaded straight into his consciousness. Given our current understanding of how the brain works, this is quite preposterous in real life but you'll be surprised to hear some scientists have tested a similar 'skill upload' system with remarkable results.

This robot sutures surgical incisions like a STAR: it's better than doctors

Thanks to robots, surgery has gone a long way since these have been introduced in the '80s making operations safer and less invasive. Now, surgical robots are starting to migrate from assistant to leading roles, which is where experts say they will really shine.

Medical errors ranked as the third leading cause of death in the United States

When researchers at John Hopkins factored human errors they found this was the third leading cause of death in the United States, surpassing respiratory diseases.

Why there are only three dimensions in this reality

By all account, we can only perceive three spatial dimensions: width, length and height. Everything seems more vibrant and 'real' in 3-D, compared to 2-D, but one can only wonder what things must look in four dimensions. Alas, our brains simply can't fathom a four-dimensional universe, let alone a 99-dimension universe. Moreover, it seems our Universe simply can't host more than three dimensions due to the laws of thermodynamics, physicists say.

Left-handed males have better math skills

Being left-handed isn't easy in a right-handed world. Let me tell you, though, at least you're better at math!

Japan has more electric car charging stations than gas stations

How to read the nutritional facts label

Nutritional labels can be daunting to read if you have no idea what to look for. Most of us don’t have the time and energy to work out what these mean, so we buy on impulse. Naturally, you’d think something as important as a product’s nutritional facts was presented in a more straightforward manner. But […]

There's a one in 10 billion trillion chance humanity is the only advanced life in the Universe

There are as many as 400 billion stars in the Milky Way alone. In this sea of light, it seems inevitable that life must have evolved on some alien planets.

It happened: U.S. Government wants to resettle the first American climate change refugees

The Isle de Jean Charles that lies on the Gulf coast of Louisiana is sinking. In less than 70 years, over the 90 percent of its landmass has washed away from erosion triggered by industry, as well public works which redirected rivers. Then there were the hurricanes.
