Switching massively to electric cars could save UK drivers up to £1,000 a year on fuel costs, reducing oil imports by almost half by 2030; a similar trend could be replicated in other countries in Western Europe or in the US.
Octopus species that live in ice-cold Antarctic waters employ an unique strategy to transport oxygen to its tissue and survive, according to German researchers. The study suggests the octopuses' specialized pigments, analogous to hemoglobin in vertebrates, are in higher concentration in the Antarctic region than in warmer waters. This would help to explain why octopuses are more adapted to climate change and warming waters
The chameleon is one of the most remarkable, but also iconic creatures in the animal kingdom. It's color shifting traits has made it the subject of metaphors. A person who is a master of disguise is rightfully labeled a chameleon. But how does the elusive lizard work its magic? After years of observation and rigorous study, scientists have finally uncovered how they do it. Beneath the outer layer of skin, chameleons have special nanocrystals that are evenly spaced. These reflect light and changing the spacing between the crystals also changes what kind of light gets reflected and eventually hits our eyes. Ultimately, this is how the chameleon turns green from red only a few minutes ago, or vice versa.
People generally love their pets, but we'd be lying to say there isn't an inter-species discrimination. How many fish owners do you know who've been with their goldfish to a veterinarian? Not that many, I presume. Certainly, number-wise it pales in comparison to dogs or cats. The story of a Scottish goldfish named Star which had its cancerous eye removed by doctors thus serves as a noble example of respect and responsibility that all pet owners should bear.
Tomorrow, Swiss aviators Bertrand Piccard and André Borschberg will embark on an epic journey aboard Solar Impulse 2 - an airplane entirely powered by solar power - that will take them around the world. The five-months, 35,000 kilometers long trip will start and end in Dubai.
In Florida, some have already found a solution to climate change: just ignore the damn thing! According to a outrageous report released by the Florida Center for Investigative Reporting, employees of the Florida Department of Environmental Protection have been ordered to stop using key terms like “global warming” or “climate change” in public communications, be them […]
By 2050, world population is expected to rise to nine billion, but the amount of arable land meant to grow food will remain mostly the same as it stands today. As such, a 25% increase in productivity is mandated to support not just a growing populace, but also a wealthier one - as income inequality is coming down in developing countries, we're also seeing a sharp increase in meat consumption, for instance. Genetically modified organisms and waste management are just a few paramount solutions. At the same time, productivity stems from agricultural processes and some modern farmers are already integrating the latest technology to increase their yields and cut costs. Twenty years from now, expect your oranges and corn to be 100% sown, grown and harvested by robots.
The Catalina Fox simply can't catch a break - it went from endangered, to doing so well that local residents want to kill it again.
This eagle at Codorus State Park in Pennsylvania has had it up to his neck with snow – both parents, mother and father, have taken parenting to the next level, sharing egg duty despite the growing snow. The Bald Eagle, recently taken off the endangered list, is a sea eagle. It’s an opportunistic species that subsists […]
Solar power is one of the most efficient yet clean sources of energy we have access to. There are no increased fuel costs or dependencies, no ties to pollutants, and it’s both reliable and affordable. Of course, in order to harness solar power you need access to specific technology. This tech relies on either small-scale […]
The pace and scale of China’s economic transformation have no historical precedent. In 1979, China initiated a series of reforms which set the country in economic high gear producing some of the most fundamental changes ever to occur in any country. China’s annual average GDP per capita growth in the last ten year period was 9.9 […]
Praying mantises are peculiar creatures, by human standards. The insect often stands in a pose that looks like it is praying, but make no mistake - it's a formidable killer and an unforgiving lover. The unholy mantis uses its spiky front legs with great accuracy to ledge unto prey, but also to hold onto its male lover after mating to chop of his head. Ouch! A less known aspect of praying mantises is their agility. The insects make extremely calculated leaps and controlled landings, all in the blink of an aye. Now, a team from University of Cambridge and University of Bristol, UK, have found out how they manage their acrobatic feats. In short, it's a complex interplay between the counter-rotation of three body parts to exchange momentum. This orients the insect towards its target with great precision.
It amazes me when I hear people say they're against wind turbines because ... wait for it... they're ugly. If you think the same, please get a look at this. Others hate them because they have this misguided impression they're noisy. Well, modern turbines at least are quieter than a heartbeat. If you really want to make a case against wind turbines, you could argue they're bad for wildlife and you'd be right. Birds, bats and other winged creatures are sometimes attracted by the turbines or get slashed when these are in the way of their migration patterns. This is why I believe turbines should be built only in those areas where there is minimal interference with wildlife. They'll always be downsides to any technology or infrastructure development, but when you draw the line we must be objective whether or not the benefits tip the scales. There's also another added benefit to turbines you likely never heard about: they help crops grow faster and better when they're placed on farmland.
It’s not every day that species get such awesome names – but then again, it’s not every day that such awesome spiders are discovered. Two gorgeous new species of spider have been discovered in Australia (where else?), and the researchers who made the discovery decided to give them these memorable names. The species are a part […]
A private company in Hong Kong known as the Hong Kong Nicaragua Canal Development Investment Company (HKND) has been given the green light to start the $50 billion work on a canal that will connect the Pacific and the Atlantic Ocean through Nicaragua. The project, which will be significantly longer than the Panama canal could bring huge economic benefits, saving a lot of time and resources, but it also raises major environmental concerns.
Using both modern and historic measurements, researchers now have a more extensive view of how the Arctic sea ice has changed in the past few decades, finding that the ice is melting much faster than previously expected. The ice in the central Arctic Ocean thinned 65 percent between 1975 and 2012, from 11.7 feet (3.59 meters) to 4.1 feet (1.25 m).
One of the world's most iconic and well known monuments - the Eiffel Tower - just got even better: the French authorities have installed two vertical axis wind turbines to power, at least partially, the tower's electrical requirements.
The UK boasts 650,000 solar installations across homes, offices, schools, churches, warehouses, farms, police stations, train stations and even a bridge. It's been one of the fastest growing solar markets in Europe. At the end of 2013, there were 2.8GW of solar power arrays installed, but by the end of 2014 this figure climbed to 5GW or nearly double in only 12 months. However, drastic and discriminatory changes in renewable subsidies to come in effect in May of this year are expected to collapse solar development to 1% of its current level.
When she was pregnant, former Chinese news anchor Chai Jing got some tragic news - her unborn daughter was diagnosed with a tumour. She immediately quit her job, and soon started working on a documentary focusing on China's pollution problem (especially smog). Now, her self-financed documentary, for which she paid $200,000 took the country by storm, with 75 million hits on the day it was released on Chinese video streaming sites and over 250 million views now.
Most of the time, the so-called civilized world would just rather turn a blind eye towards what is happening in Africa; right now, I'd like to shed some light on what it's like to be an albino in Africa, and more specific, Tanzania.
India is among the most polluted country in the world, a direct consequence of its growth-orientated policy. Despite economic growth, the health of Indians is suffering significantly. According to researchers at University of Chicago, Harvard and Yale, pollution is directly responsible for shortening the lives of 660 million Indians who live in sensitive areas by three years on […]
Big cities are crammed with millions of pigeons, but despite their large numbers the birds seem to have no problem navigating through bustling urban environments. I've often wondered how pigeons manage not to hit each other, first of all, when they sudden burst in a flock or why you never seem to see pigeons hit by taxis or poles. A new study suggests that this remarkable dodging is made by the pigeon through a trade-off between efficiency and safety, depending on the situation.
The link between climate change and violent conflict has been thrown about often, but a recent study is the first to support this hypothesis with qualitative evidence. US researchers found that widespread droughts and increased temperatures amplified an already heightened state of unrest in Syria, which may have triggered the civil war still raging on today.
They like freezing conditions, but the Emperor penguins struggled during the last Ice Age, a new study concluded. In fact, if they hadn't been able to change their breeding habits and even their genetic make-up, they might have not survived.
We all know how therapeutic and soothing (or on the contrary, motivating) music can be; and we all know that different people like different types of music... so it seems safe to say that different animals also like different types of music. Now, a joint team of scientists and musicians believe they found how to compose the purr-fect music for animals, including monkeys and cats.
When we're talking about CO2 emissions and global warming, we generally mean atmospheric CO2 - where the gas is spewed and generates the greenhouse effect, warming our atmosphere and subsequently, our planet. But a new study conducted by US researchers found that CO2 actually warms the Earth's crust directly; the more CO2 we emit, the hotter our planet will get.
The world's first grid-connected wave power station has just been activated off the coast of Australia. Taking energy directly from the waves and sending them to the grid is a remarkable achievement which will hopefully be replicated in Australia, as well as in other parts of the world.
This gentle and secluded creature is called a pangolin. Bet you've never heard of him. It looks sort of like a walking pinecone, a dragon or a dinosaur. It's tongue is as long as its body and can curl, then roll in a scaly ball. It's a pretty amazing animal and it's a shame so few people know of its existence. But more worrisome is that the pangolin might cease to existence entirely, with or without we knowing about it. Many believe it's the most trafficked animal in the world.
Memories aren't infallible - even for those with photographic memory - so, more often than not, they'll seem fuzzy. And the older these get, the fuzzier they're recalled. Mixing names, faces and events in your head can sometimes be embarrassing, but at least we're not alone. Seems like bees have false memories too, according to a study made by British researchers at Queen Mary University of London. Previously, false memories had been induced in other animals, like mice, but this is the first time natural false memories have been shown to happen. Research like this might help us, in time, understand how false memories are formed and, in a more general sense, how we recall events.
One of the prime arguments climate change skeptics throw about is how surface temperatures have remained more or less constant for the past 15 years, hence there is no man-made global warming – it’s all a sham, a conspiracy to keep scientists busy with gratuitous grants and fill Al Gore’s pockets. I’ve written previously about […]
Paleontologists have excavated and analyzed the remains of an ancient hypo ancestor in Kenya. The 28 million-year-old fossils paint a broader picture revealing the missing link between modern day hippos and the earliest ancestor who lived some 53 million years ago. As an interesting tidbit, the closest living relatives of the hippo are whales and […]
Building vertical farms is innovative and can have significant advantages, done properly; but building a vertical farm in the middle of a city... that's just awesome! In downtown Jackson, Wyoming, developers are working on a vertical veggie farm which just might revolutionize urban food growing.
Rats remember acts of kindness done by other rats, and are more helpful to individuals who previously helped them. It's not clear if they do this because they are grateful or if they are trying to make sure that they will get helped in the future as well, but their behavior gives scientists a new understanding of animal social behavior.
Mollusks such as oysters, clams and scallops are highly vulnerable to the increasing acidification of the world's oceans. A new study concluded that the acidification is so intense that the mollusks aren't able to properly produce a hard shell, putting them in peril.
Wei-Hock Soon, an aerospace engineer and a part-time employee at the Harvard-Smithsonian Center for Astrophysics is one of the few respected scientists who spoke against the general consensus that human activity is a significant contributor to climate change. He has published 11 papers on climate change since 2008. However, it was recently shown that he received $1.2 million from oil companies in exchange for his "science". According to leaked documents, the papers were simply “deliverables” that he completed in exchange for their money. He used the same term to describe a testimony he prepared for Congress.
Marine animals today are 150 times larger than they were 540 million years ago, according to a new study which seems to suggest evolution favors animals bigger in size.
Until now, only two species of seadragon had been reported, with the last one being discovered 150 years ago! Now, biologists have discovered a new species off the coast of Australia: a red hot sea dragon. “All this time we thought that there were only two species,” marine biologist Nerida Wilson of the Western Australia […]
The most populated city in the United States is already experiencing its fair share of floods, hurricanes and heat waves, but these will only intensify in years to come. According to the New York City Panel on Climate Change by the 2080s there could be an 8.8-degree Fahrenheit rise in temperature from 1980s levels and as many as six heat waves a year or three times as many as in the 1980s. Sea levels could also rise by as much as six feet, pressing the municipality for swift adaptive measures.
After scientists discovered a huge hole in the ozone layer above the Antarctic, an emergency UN panel banned the use of chlorofluorocarbons (CFCs) in 1987. These build up in the atmosphere, react with the triple oxygen molecule and break it down. Since then, ozone has thankfully replenished, thought it might take decades before it reverts to pre-1980 levels. Progress is slow because there are still some plants through out the world who illegally use CFCs (the stuff that used to go into refrigerants or deodorants), but also because there are other ozone-depleting chemicals out there - some recognized, others new and extremely dangerous. One class of chemicals that has been allowed in the industry since the Montreal Protocol, despite the danger it posses to ozone, is made up of so-called 'very short-lived substances' (VSLS) which breakup in under six months. A new study, however, found that these have dramatically increased over the past couple of years and despite their short reaction times, these could prove to be extremely dangerous.
As global oil prices continue to drastically fluctuate up and down over the years, the Kingdom of Jordan has announced that all of their mosques will soon run on solar energy, in an attempt to save money and promote sustainable development.
Pollution talks are often about the atmopshere, but we tend to foger that the most part of the pollution goes into the oceans. About a quarter of the carbon dioxide emitted by humans ends up in the seas, which causes them to become more acidic, significantly altering the oceanic environment on which corals, fish, and ultimately, we depend on.
The Mercury level in tuna has been a subject of debate for decades now. Paul Drevnick, Assistant Research Scientist at University of Michigan and his team analyzed data from over the past 50 years and found that mercury levels in Pacific yellowfin tuna, often marketed as ahi tuna, is increasing at 3.8% per year. If 3.8% per year doesn't seem like much, that translates into a doubling at every 20 years. So in 50 years, mercury levels have increased 6 times.
We know that things like eye or skin colour are encoded in our DNA and passed down by our parents, but many other traits are significantly influenced by another hereditary mechanism: bacterial offspring. A paper in Nature suggests microbes are passed down from mother mice to pups, passing down traits similarly to how genes influence illness and health.
Bald Eagles are bouncing back from the brink of extinction, research shows. The official US mascot is now thriving and populations are continuously growing, but challenges are not yet over.
Speaking at the 2015 AAAS Annual Meeting, US researchers showed a coloured map of the quietest regions in the United States, based on 1.5 million hours of acoustical monitoring from places as remote as Dinosaur National Monument in Utah and as urban as New York City. Apparently, the eastern half of the country is much more loud […]
The Dutch Windwheel is a concept for a sustainable landmark that will not only generate wind energy silently, but also capture rainwater, recycle tap water, produce biogas - and most importantly, house 72 apartments. It will also have some rotating cabins providing a brilliant view of the Dutch city of Rotterdam.
Fox Glacier is one of the most spectacular sights in New Zealand, receiving on average over 1,000 visits every day. Sadly, like many other glaciers, Fox Glacier is retreating rapidly due to climate change. A pair of before-and-after images 10 year apart highlightthis perfectly, just like the time-lapse video below does.
A new study has revealed the fun-loving side of crocodiles; the reptiles, generally regarded as ferocious and aggressive, are reported to surf waves, play ball and engage in piggyback rides to have fun.
Our oceans are clogged with plastic – that’s already a well known fact by now. A major study in 2014 concluded that there are over 5 trillion pieces of plastic in the world’s oceans, while another one suggests that the ocean’s bottom might also be a cemetery for garbage. To make things even worse, there’s […]
Science confirms what every dog owner has known in his heart: our canine friends can tell when we're happy or upset. The discovery represents the first solid evidence that an animal other than humans can discriminate between emotional expressions on other species.
