According to a study from Women’s College Hospital and the Institute for Clinical Evaluative Sciences (ICES), Canada, it doesn’t matter whether you live in a rural or urban setting when it comes to heart disease – the risk if the same for both environments. The general consensus is that those living in rural areas are at a disadvantage as far…

Scientists find life at 20 km deep

A Yale undergrad may force us to rewrite geology and biology books, after reporting a find which suggests that life can exist much deeper than currently believed, at temperatures at which DNA is barely stable. Geologists found carbon isotopes in rocks on Washington state’s South Lopez Island; these isotopes suggest the minerals grew from fluids flush with microbial methane. Microbial methane…

Climate change has many unexpected consequences – as a research has shown yet again. This time, a team of Montana scientists have shown that the tea flavors are changing, mainly as a result of shifting rainfall patterns. This variability can jeopardize the livelihood of tea growers and has significant effects on the end product we drink. Tea is the most…

Megalodon extinction paved the way for whale development

megalodon.

Megalodon is quite possibly the most dangerous predator to ever live in the Earth’s waters in the recent geological history – roaming the seas between 28 to 1-3 million years ago. We’re still not sure why it went extinct, but a recent study suggests that its extinction paved the way for whales to grow more and more, reaching the enormous sizes we…

Killer whales are so smart they can learn to speak “dolphin”

Killer whales are smart, we already know that; they’re also really scary. But a new study has shown that they are actually scary smart – up to the point where they can learn the language of another species. Killer Smart Killer whales are actually a species of dolphins found in all oceans, from the frigid Arctic and Antarctic regions to tropical seas….

Fossils Reveal “Beer-Bellied” Dinosaur

Image via Scientific American.

It was about as big as T-Rex, but not quite as fit – new fossils have revealed that Deinocheirus mirificus had quite a beer belly. “This is an entirely new body plan” for such dinosaurs, says Stephen Brusatte, a vertebrate palaeontologist at the University of Edinburgh, UK. Indeed, few scientists would have imagined such a scientific appearance. The first fossils of Deinocheirus mirificus (which means ‘unusual…

Goby fish hide in plain sight by changing their colors

When you think about changing colors, the word ‘chameleon’ usually comes to mind. But there are other animals which can change their colors – the mimic octopus is the most noteworthy example, and there’s also the fish that mimics the mimic octopus. Now, researchers have found yet another fish which can change its color – the simple rock goby. Rock gobies,…

How you get Ingrown Toenails, explained by Science

ingrown_toenail

Having a ingrown toenail could ruin your day and a lot after if you don’t have it fixed. Yet, even though ingrown nails and other nail-related conditions are common and pesky, very little is known about them. Now, a team at University of Nottingham have published a mathematical model that explains what forces are tugged beneath your finger nails and what exactly happens when…

Regeneration of the spinal chord following a paralyzing injury was thought to be impossible, but groundbreaking efforts stirred by surgeons in Poland and Britain have turned this paradigm upside down. A team of dedicated surgeons and scientists transplanted  cells from the nasal cavity of a patient who had been paralyzed from the waist down for more than two years into…

A Rogue gone Good: Mitochondria was initially an Energy Parasite

Image: knowingneurons.com

A new milestone study found that mitochondria – the energy factories in animal and plant cells – were initially very similar to parasitic bacteria some two billion years ago, and only later did they become energy sources. Very little is known about the origins of mitochondria, but by probing the genomes of bacteria closely related to the energy cell scientists at University…
