For decades now, scientists have known what are the biochemical reactions that trigger a penile erection, however not those that actually maintain it. In a breakthrough, physicians at Johns Hopkins Medicine have finally uncovered the exact biochemical chain of events involved in the process. The findings will hopefully lead to novel medical treatment for patients suffering […]
Australian scientists say that persons with psychopathic tendencies could be spotted through a smell test, correlated with a psychological questionnaire. The link doesn’t lye in the actual odor emanated by a potentially psychopathic person, though, but rather in their sense of smell. The study conducted by Mehmet Mahmut and Richard Stevenson, from Macquarie University, is based on […]
These little spiny African mice can do something no other mammal can: they completely regenerate damaged tissue, a feat once thought impossible. They may not look as impressive as Wolverine, but they held quite the surprise: Acomys kempi and Acomys percivali have skin so brittle and easily torn that one can only ask… why? What […]
In a remarkable feat of science, scientists at Harvard University have surpassed seemingly insurmountable technological challenges have managed to take over the behavior of a lab worm.

We often like to think us humans have achieved a remarkable standard of efficiency and development – but a look at the animal life around us is often enough to humble us. Replicating bacteria and physics The common gut bacteria, Escherichia coli (E. coli, in short) typically takes about 20 minutes to duplicate itself in […]
A feline genetic study has revealed that a particular gene variation in a cat’s chromosome is responsible for the stripped fur so many cat lovers adore. According to the researchers, the same gene gives cheetahs, the house cat’s larger and wilder cousin, stripes instead of the regular spots. The research was lead by Stephen O’Brien of […]
Neuroscientists at the Allen Institute for Brain Science in Seattle have created an atlas of the human brain, which highlights the activity of genes across the entire organ. The brain map was created after many hard years of labor, and might help scientists from across the world identify factors that underlie neurological and psychiatric conditions. The human brain is […]
Culturing mammalian cells is currently the only way to make some complex proteins used in certain drugs; but growing such cultures is an extremely difficult and delicate job, because they can harbor human pathogens and must therefore be kept under strict temperature conditions. It’s a difficult job, but it’s definitely worth it; take a look […]
Scientists have finally managed to track sperm patterns in 3D, for the first time in history.

Horses are arguably one of the most helpful animals man has ever managed to domesticate. At first they were used as source of meat and milk, but it was soon evident that horses were a lot more suited as labor animals than as a direct food medium. Important agricultural advancements were made possible thanks to horses, and […]
You may call them ‘healers’, you may call them ‘quacks’, but a scientific study conducted in Spain has shown many of these people display a neuropsychological phenomenon known as “synesthesia” (specifically, “emotional synesthesia”), giving a valuable explanation of their ‘abilities’. The name ‘synesthesia’ explains the condition pretty good: in Green, ‘syn‘ means ‘together‘ and ‘aisthesys‘ […]
Energy and sports drink do give you a quick rush when you might feel like nothing else can do the trick for you – but at a huge cost. Aside from all the other downsides, which include heart and stomach issues, researchers have now shown that people who drink this kind of drinks are essentially […]
Skin and hair color are most inherited from parents, and usually hint pretty accurately to a person’s ethnicity.
