Archeologists have found evidence of fire being made a million years ago in South Africa, 300,000 years earlier than known before and well before modern humans.
We've always known, informally, that animals can make friends, even across species. Not too surprisingly, this turns out to have the same health benefits for them as it does for us.
Yes! It had to be! The Ice Age featured sabre-toothed lemmings.
Bisphenol A (BPA) is a chemical added to plastics to make them soft and pliable. It also resembles estrogen and other hormones. In response to law suits, the FDA has finally examined the issue, but has decided the evidence for BPA being harmful to humans in insufficient. However, the EU, Canada, and several states have banned its use in baby bottles, and several bug food companies have already removed BPA from their packaging.
Medical researchers have found an antibody that shrinks a wide variety of human tumors when transplanted into a mouse. It appears to block a "don't-eat-me" signal that tumor cells give off. When that signal goes off, the body's own immune system moves in.
Taking a nap right after some hard brain-work, e.g. a stiff class, helps the information soak in.
Solar energy is usually soaked up in plain, flat sheets. New research proposes a better arrangement, in crinkly stacks.
By now, astronomers have found a fair number of planets similar to Earth (rocky) but larger. We can only find them when they pass in front of their suns, causing a slight flicker. Based on that, astronomers have estimate the number of super-Earths out there that we can't yet see. There are probably several dozen within 30 light-years. We can't make a direct extrapolation to the number of actually Earth-like planets, but it looks promising.
Dolphins are difficult to study, given the environmental barrier, but new studies indicate they have intricate and shifting, soap-opera-like social lives, especially the males, who form long-lasting friendships in twos and threes.
The "Sand Flea" is a little box on wheels, which works equally well either way up, and which leaps at least one story high. It's brought to you by the same people who produced the galloping "Cheetah" robot, the trotting "Big Dog," and the bipedal "PetMan." All of them fall deep into the Uncanny Valley, as far as I'm concerned.
Some number of cases of obsessive-compulsive disorder (OCD) may be caused by bacterial infection and therefore treatable by antibiotics.
