Gun violence in America in one Inglorious Map

This map shows what gun ownership on a per capita basis looks like around the world, based on data compiled by the Guardian. As you can see from the color codes, the United States tops the list being home to 88.8 guns per 100 people! The only country that marginally comes close is Yemen with 54.8 guns per 100 people.

Google and NASA say quantum computer works (with a catch): 100 million times faster than single core processor

Researchers run a problem on a quantum machine and found it performed 100 million times faster than a conventional processor.

State of emergency in Beijing after city issues smog Red Alert for the first time

Talks are in full force in Paris at the COP21 climate change conference, but meanwhile in China, Beijing is going through one of its hardest smog events ever. The mayor of Beijing announced on Monday its first red alert for pollution, showing that Chinese smog is still a huge problem.

A few words on how a well stocked library can drastically improve academic performance later in life for your children.

How to build a human, in one amazing infographic

It all starts with a lucky spermatozoon and one egg. When the two merge, a genetically unique entity is formed shortly thereafter, called a zygote which has half of its DNA from the sperm, and the other half from the egg. The zygote first divides into two identical cells, called blastomeres. Five days after conception, the grouping of cells are now called a blastocyst. A cavity appears in its center. It has an inner group of cells which will become the embryo and later the fetus, and still later the newborn. In between, there's a lot of things happening and this fantastic animated infographic designed by Eleanor Lutz does a great job summing things up visually.

Carbon tax critical to stopping runaway global warming, Elon Musk said in Paris

Elon Musk - involved with cutting-edge tech companies like Tesla, SpaceX and Solar city - told youngsters gathered at an event at the University of Sorbonne, Paris that carbon pricing would accelerate the transition from fossil fuels to a renewable energy economy.

'The 2 degrees goal is a political figure, not generated by scientific reports', says IPCC at COP21

Today, at a press conference at COP21, a panel of scientists and chairmen from the IPCC said that they never suggested one or the other figures as a baseline for averting climate change. "The 2 degree goal is a political figure, not generated by scientific reports," the panel warned.

The 2,440 new coal fired power plants expected by 2030 could destroy 2 degrees warming target

Some 2,440 new coal fired plants are expected to come online by 2030 in eight countries like India, China, Indonesia and the European Union. Combined with already existing plants, their emissions make averting 2 degrees of warming past industrial levels impossible, and the respective countries' national pledges aimed at curbing emissions - the so-called INDCs - now sound completely ridiculous.

What touching Fairy Holograms in mid-air looks like

Most people would love to a holographic display in their rooms, and seriously you might not have to wait too long for this to happen. Japanese researchers demonstrate how lasers can be used to manipulate holograms.

Almost $3.4 trillion divested away from fossil fuel, $800 bn. more than in September

More than 500 institutions representing over $3.4 trillion chose to divest away from fossil fuels, $800 million of which only in the past 10 weeks.

Some of the pledges at COP21 need to be legally binding, says President Obama

President Obama voiced his concerns that any agreement made in Paris, COP21 will be ineffective if it lacks the force of treaties.

King coal is dying: demand peaked in 2014 and dropping fast worldwide

A report released by the Institute for Energy Economics and Financial Analysis (IEEFA) found we are beyond the peak of coal consumption and demand. Effectively, the demand for coal has virtually dropped all over the world with few exceptions, most notably India. The news suggests we're well on our way to leave coal behind for good, and never turn back. Replacing coal are more efficient and energy friendly measures,including renewable energy, nuclear and gas.

Scientists find new phase of carbon at room-temp that's harder than diamond

To make diamonds, the industry typically resorts to subjecting graphite to immense pressure and temperature, which makes production volumes low and costly. This paradigm is about to change, since researchers at North Carolina State University found a new phase for carbon called Q-carbon, produced at ambient temperatures and pressure. This is surprisingly close to diamond in structure, with the added benefit of exhibiting a couple of unique properties.

Some of the richest in the world join Bill Gates to invest in the biggest private climate fund

Bill Gates and 27 other billionaires with a collective net worth of $350 billion have joined forces to launch the biggest private climate fund in history. The multi-billion dollar fund, called the Breakthrough Energy Coalition, will focus on cutting edge research and development to accelerate the growth of renewable energy and other sustainable technologies.

Bill Gates to launch multi-billion climate fund - the biggest ever

The wealthiest man in the world, Bill Gates, will announce on Monday a massive private-government partnership for a new clean energy research fund. This is reportedly the biggest research and development fund for clean energy ever, which will funnel billions to support innovation in this section. The precise details of the multi-billion partnership will be revealed once with the opening of the United Nations conference on climate change in Paris.

Head of (anti)-science in America harasses NOAA over paper that refutes global warming hiatus

You know things are messed up when the head of the House committee that covers science doesn't really understand it. Or, worse even, chooses to bury it and persecute scientists. Such is the case of Rep. Lamar Smith (R-TX), the chairman of the House Committee on Science, Space, and Technology, who suspects of fraud a group of scientists that explained in a new paper that the global warming hiatus isn't actually thing. Seems like the world is warming at the same rate as in the 20th century - fast. That didn't bode well with an obviously biased conservative Republican, so Smith subpoenaed the National Oceanic and Atmospheric Administration to gain access to the private documents and emails of scientists involved in the study.

Scientists are teaching robots to say 'No' to commands. Is that a good thing?

Researchers at Tufts alter the laws of robotics to teach robots to say "no".

Congress passes law that makes extracting resources in space fair game

Officially, US citizens are now entitled to any resources they mine off the moon, asteroid or any celestial body outside Earth.

Finally, the metal wiring in solar cells might stop reflecting light. One up solar efficiency

There's an inherent flaw in solar cells: the metal wiring that's quintessential to harnessing the electrons reflects the incoming light, acting like a mirror. Now, must people would brush off this issue and leave it like that. It's a necessary trade off. But a team at Stanford University devised an elegant chemical technique that basically hides the wiring with silicon, away from the light while preserving energy harnessing. Metal wires cover 5 to 10 percent of a solar cell's surface. Now, in the same area more light can be absorbed, hence more electricity generated which jumps the efficiency. Of course, this also means cheaper solar panels -- if only the chemical technique is covered by the recurring costs of increased efficiency.

Scientists play with a flatworm and grow another species' head instead

It sounds like a plot from Frankenstein, but apparently there's no limit to how versatile flatworms can be. Previously, researchers at Tufts University determined that the small, yellow worm can retain its memories after it head was severed. As a reminder, flatworms can regrew new heads following decapitation. Now, the same team yet again guillotined some flatworms and interrupted gap junctions, which are protein channels that enable cells to communicate with each other by passing electrical signals back and forth - just to see what would happen. Yes, the flatworm grew a new head, but it was that of another flatworm species. They eventually induced the same flatworm species to grow the heads and brains of multiple other, closely related species. There's a lot of biology and behaviour encoded in genes, but these findings show that tweaking physiological mechanisms in a live body can actually cause new anatomical developments. We might have uncovered a new form of epigenetics.

Sanders to GOP candidates: 'To hell with the fossil fuel industry'

While in South Carolina last weekend, Democrat Presidential candidate Bernie Sanders reiterated a burn he's been feeling for decades: the vested interests of the fossil fuel industry. He told the crowd climate change “is already causing devastating problems all over this world,” and the fossil fuel industry, Koch brothers specifically, are doing everything they can do keep this out of the public's attention. At one point he directly called out Republican candidates to basically man up, grow a backbone and stop lying.

Alberta, Canada taxes carbon emission from 2017 and phases out coal by 2030

Earlier this year, the New Democratic Party took power after 44-years of Conservative rule. Canadians have lot of emotions and hopes invested in the new government, and so far so good. Alberta Premier Rachel Notley recently announced a series of environmental measures which will see the country drastically lower its carbon footprint, expand the renewable energy sector and lower its reliance on fossil fuels.

UK will shut down all coal plants by 2025, replaces with gas

Amber Rudd, the UK's Secretary of Energy and Climate Change, announced the government's new plan to generate clean and cheap energy. Rudd says the Britain will add more nuclear power, explore for shale and, most strikingly, replace all coal fired plants with gas.

Blue Origin makes space history: first controlled landing for a rocket

Jeff Bezos just announced a historical feat: Blue Origin, his space company, successfully launched its New Shepard rocket to 329,839 feet — or sub-orbital space — then safely landed the used rocket just a feet away from the launch pad. This is the first time a controlled landing was demonstrated for a rocket, beating Elon Musk's similar efforts to safely land his Falcon 9 rocket. This monumental milestone suggests reusable rockets will shortly become a reality, revolutionizing space flight in the process.

How agriculture shaped our genes through natural selection

Once with the advent of agriculture, and its spread to Europe from the Near East, human society was transformed forever. Resources became more plentiful, communities could stay in one place and develop, and humans were free to pursue other activities. Agriculture turbo boosted the division of labor, an essential prerequisite to any civilization. Agriculture not only transformed human society, it also modified our DNA. A first of its kind study compared the DNA of ancient humans who lived between 8,500 and 2,300 years ago. The analysis revealed that humans underwent widespread genetic changes that influence height, immune system, digestion and skin colour once agriculture was introduced.

Large corporations are buying 75% more clean energy than last year

Starting November 30, the world's leaders will meet in Paris at the UN summit for climate change to discuss a common framework to reduce carbon emissions at a global level. Most countries already have plans set in motion to reduce emissions, either by using energy efficiency and new technology to lower the carbon footprint of their own operations, or use legislation to compel residents and companies to do the same. A lot of big and sizable corporations in the United States have taken matters into their own hands, however, by buying more clean energy and less fossil fuel derived energy, regardless of what the government suggests or coerces.

Shackleton's 1915 expedition to Antarctica showcased in New Photos

n 1911, Norwegian explorer Roald Amundsen reached the South Pole, followed by Scott who died on the return journey. Shackleton searched in his mind for some other daring goal. He finally settled on crossing of the Antarctic continent from coast to coast via the South Pole, a distance of about 1800 miles.

Classic formula for 'pi' connects pure math and quantum mechanics like a 'magic trick'

Until the advent of calculus and computing infinite series, not that many digits were added to the ones found by Archimedes for more than a 1,500 years.

How some fish use polarized light to make themselves invisible to predators

You'd think there's not much a little fish can do to hide from predators in open waters. But when rocks, algae and other marine nooks and crannies are nowhere to be found, fish turn to manipulate the physical interactions of light to balance the scale. For instance, some open ocean fish species employ specialized skin cells that reflect polarized light. This reflection is most effective, not coincidentally, at the 'chase angle' or from the predator's point of view. It's so effective that the US Navy is funding work that might shed light how exactly some fish do this and how this can be applied to make submersibles equally inconspicuous.

Half of Amazon rainforest tree species threatened by deforestation

The Amazon basin is home to the world's great biodiversity. You'll find more plant and animal species per square foot than anywhere else in the world. It's truly one of the wildest and life teeming places in the universe, which given humans' habit of meddling makes it one of the most vulnerable as well. The huge 6-million-square-kilometer rainforest area remains mostly unstudied, due to the roughness and inaccessibility of the land. But making their way through the outskirts are the chainsaws and sawmills; and they're moving fast. Since 2000 an area equal to 50 football pitches has been destroyed every minute in the Amazon rainforest, satellite imagery revealed.

More young Americans support evolution in favor of creationism

As more Millennials are leaving religion in droves, or choosing not to identify with any faith, acceptance of evolution among the public strengthens.

FDA approves first genetically modified animal: a salmon that grows twice as fast

After five years long of pondering, the FDA finally gave the green light for a genetically modified Atlantic salmon variety. This is the first food animal that was genetically modified that the FDA approved for human consumption and farming. The salmon has genes from another salmon species, as well as an eel-like fish, which allows it to grow to market size in half the time it would usually take. This means it saves twice as much time and resources as conventional salmon, with no nutritional or health drawbacks, the FDA says.

The 380-million-years old ancient forest discovered near the Arctic Pole

Some 400 million years ago, during what's called the late Devonian period, the planet went through a dramatic shift in climate. Over just a few million years, the CO2 levels in the atmosphere dropped 15-fold. Partially or mostly responsible for this phenomenal climate change event were the very first forests which evolved and started claiming the Earth. Until then, plants were less specialized and smaller. We know little of these troublesome times, but we're learning along the way. The discovery of an ancient 380 million years forest in Norway will definitely help in this endeavor.

Costa Rica went 255 days on almost 100% renewable energy

The small Central American nation got rid of its armed forced 65 years ago, and the Ticos are a happier people for it. Now, Costa Rica - home to four and a half million people - is setting the world a new example in human values: for 255 days it has managed its resident's energy needs with little fossil fuel use.

Jellyfish degenerates into mucus parasite: another amazing quirk of evolution

This may be the first known case of simplification from a macro to a microorganism, a cheap trick which evolution likely used more than once though.

Lending a voice: a working vocal cord tissue grown in the lab

About 20 million people in the United States suffer from temporary or permanent voice impairment. Life can sound like a nightmare, even though we don't hear our own voice - but we do feel the attention. Then, those are those rare cases which basically render people mute. While there are various medical interventions that can improve one's voice, it's still far from the real deal. What these people need is not a patch here and there, but a whole new set of vocal cords, and a group of researchers has set out to grow it in the lab. Starting from a couple of human cells, they've grown a critical tissue involved in vocalizing. It's basically indistinguishable from the real deal (it's still biological tissue after all) and biocompatible.

How Google Maps can tell if there are traffic jams

Ever wondered how Google Maps can predict traffic jams?

Human brain plasticity doesn't seem to be shared by chimps - is this a unique gift?

It seems like evolution has fostered us humans all along for us to become the dominant species on planet Earth. We owe so many gifts to the tender processes that began millions of years ago and shaped us the way we are today. Gripping dexterous hands, remarkable social behavior and lets not forget about those big brains. It's not enough to have a big brain, though. What makes us humans particularly successful is our ability to adapt constantly to our environment. Humans fair well in luxurious plains, but they seem to survive in the desert as well. Then look at the times we're living in. Technology, networking, all our cultural heritage. It takes a lot to adapt to such changing times, and no other species seems to be this good at it. While we owe a great deal to genetics, it's brain plasticity - an inherent ability to mold our cerebral connections to fit our environment - that took us the extra mile.

Federal gov. cracking down on $40 billion (snake oil) dietary supplement industry

The FDA, Department of Justice and other government agencies, today presented the results of a yearlong sweep of dietary supplements which are thought to contain unsafe compounds. Following a slew of illnesses and law suits as a results of dietary supplement intake, the combined government effort vowed to crack down on the industry - at least the part that mislabels its products and poses a significant hazard to the population. You'd think drugs - what a lot of supplements contain - would be regulated by the FDA, but dietary supplements are entirely unregulated. This has allowed a $40 billion industry of "snake oil" products to flourish. Not anymore, everyone hopes.

Quantum version of computer code proven to work in silicon chip

University of New South Wales devised a two-qubit system inside a silicon chip and ran a computer code adapted to the quantum world. Their code passed the notoriously intransigent 'Bell test', making it the strongest evidence yet that quantum computers can be instructed to handle operations.

How bats land upside down - mysterious acrobatic feat revealed

The bat is the only flying mammal and among the heaviest in the world. To top it over, it can land upside down a perplexing acrobatic feat which has left scientists scratching their heads for many years. After carefully and systematically studying bat upside landings in slow motion, a group of researchers thinks it has cracked the puzzle: bats employ a nifty trick where one wing stays flapping while the other is moved close to the body. This asymmetry corrects the moment of inertia and center of mass so the bats always land safely upside down.

Prematurity is the leading cause of death in infants. What you need to know

Today is World Prematurity Day - a global effort to raise awareness about the deaths and disabilities due to premature births. Each year around the world, 15 million babies are delivered ahead of term and 1 million children die before their fifth birthday from related complications. Some who make it past this dangerous threshold might get to live with serious disabilities.

There's a fourth tribe of founding European forefathers

It's widely agreed that modern Europeans trace their roots from three ancient tribes, or three important migration events, if you will. But after researchers sequenced the genomes of two hunter gatherers who lived roughly 13,000 years ago, there's evidence that suggests a fourth tribe lent our genes.
