US researchers have imaged for the first time ultra-small bacteria, whose existence has been debatable for the past couple of decades. Now, these tiny bacteria have been confirmed after samples coming from groundwater were analyzed with state of the art techniques. Very little is know about these enigmatic creatures, but it’s believed they play an important role in microbial ecosystems, despite their tiny cells harbor limited resources. The cells have an average volume of 0.009 cubic microns (one micron is one millionth of a meter). About 150 of these bacteria could fit inside an Escherichia coli cell and more than 150,000 cells could fit onto the tip of a human hair.
According to a new study, ancient hunter-gatherer Britons imported wheat from mainland Europe, showing a surprising level of sophistication for such an old population.
Who doesn’t love dinosaurs? Well sure, there’s these guys, but rational people love dinosaurs, right? Well, Nathan Myhrvold, an inventor and Microsoft’s former CEO sure does, and he believes that dinosaurs might actually help us fight malnutrition. Here’s how:
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.
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.
If you’ve ever wondered what happens inside an egg, then science has you covered – researchers have developed transparent artificial eggshells; but they didn’t do this just out of curiosity – they want to create a controlled environment for bird embryo growth and development to aid stem cell studies.
Scientists at the University of Sydney in Australia have achieved 5G speeds of 1Tbps, far exceeding existing the speeds of existing technologies. At 1 Terrabyte per second, you could download 10 movies per second.
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 models and observations that explain
Like most things in our modern day life style, we tend to take vaccines for granted. Some, in ever growing numbers, are on the contrary pushing and inciting against vaccination for all the wrong reasons. It’s easy to forget, however, that since their introduction hundreds of millions of lives have been spared. Vaccines given to infants and young children over
A complex artificial intelligence program developed by DeepMind, a London-based company which was acquired by Google last year for $400 million, mastered classic ATARI video games, like Breakout, Video Pinball, and Space Invaders. It was so effective that it outperformed professional game testers in 29 of the 49 games it tried out. As is the case with such demonstrations, there’s more to it than just humiliating humans. The same algorithms could be used to develop and improve autonomous robots or self-driving cars.
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 dolphins, as revealed by previous
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.
A while ago I wrote that the applications for graphene are endless, and it seems like scientists just want to make prove me right – University of Manchester scientists have used graphene to target and neutralise cancer stem cells while leaving healthy cells unharmed.
A partial skull fragment found in Kenya seems to indicate that early humans were much more diverse than previously thought. The 22,000-year-old skull clearly belongs to a human species, but is unlike anything else previously discovered.
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.
It’s pretty scary what modern medicine can do these days. Sergio Canavero of the Turin Advanced Neuromodulation Group in Italy announced his intention to perform a full head transplant by 2015. He will put forth a proposal at a conference in the US so interested parties can get onboard and make suggestions for the procedure.
Astronomers have discovered a humongous supermassive black hole that’s 12 billion times as massive as the Sun. What’s peculiar about it isn’t necessarily its mass – some even bigger black holes have been found – but rather its age. Observations suggest that the black hole 12.8 billion light-years away, which means what scientists are reading and observing what the black
