  • The latest update to the human migration story comes from the Greek island of Naxos, where new archaeological finds show that humans and Neanderthals have occupied the site for around 200,000 years – far earlier than previously believed.
  • A series of systematic reviews is controversially suggesting there is little to no evidence that eating red or processed meat significantly increases risk of heart disease, diabetes, or cancer.
  • Science
    ​The most numerous of organisms on Earth, bacteriophages are viruses that infect and kill bacteria. Now, scientists have grown enough of them to create a self-healing hydrogel that's made almost entirely of the things. It could have important applications in medicine, and in other fields.
  • In an effort to make vaccines​ more available to people in difficult to reach areas, a team of scientists at McMaster University has developed an inexpensive, sugary gel that can preserve heat-fragile antiviral vaccines for over eight weeks at temperatures up to 40° C (104° F).
  • Not only do firefighters have dangerous jobs, but they often work in dark, smoke-filled environments where they'd be difficult to find if they ran into trouble. A new motion-powered wearable sensor could make all the difference in such situations.
  • We've already seen lubricant-infused coatings that repel almost all substances – such coatings could be used to keep airplane wings ice-free, or to stop bacteria from accumulating in kitchens. However, what if you want to repel all substances except one? Well, scientists have now got that covered.
  • Science
    ​According to its "best before" label, that steak you bought hasn't expired yet … but is it really safe to eat? Well, thanks to research being conducted at Canada's McMaster University, the food packaging itself may soon definitively let you know the answer.
  • ​As if you really needed it, here's another reason to get more exercise: it improves your memory. That's the finding of a study recently conducted by McMaster University. And although the research involved healthy young adults, it could have big implications for older people.
  • Science
    For some time now, scientists have been looking for a way of incorporating bacteriophages (bacteria-killing viruses) into antibacterial food wrap, but it's proven difficult to keep them alive. Now, however, researchers may have found a way.​
  • ​A deficiency in vitamin D can not only cause bone problems such as rickets, but also raises the risk of death from cardiovascular disease. The good news, however, is that your dentist may soon be able to detect it before it becomes a major problem.
  • ​In March of this year, researchers showed that a probiotic found in yogurt was able to reverse symptoms of anxiety and depression in mice. Now, in a small study involving 44 adults, investigators at McMaster University in Canada have shown a different probiotic can have the same effect in humans.
  • ​Our eyes are designed to flush out any contaminants that get into them. While this is generally a good thing, it's not so helpful when it comes to administering eye drops. Now, however, a scientist is developing what could be a solution to the problem. ​
