As some parents will already know, head lice infestations can be very difficult to treat. Typically a toxic shampoo or lotion has to first be applied to the sufferer's scalp, after which the lice are removed by pulling a specialized comb through their hair. Louse eggs aren't harmed by such shampoos, however, so the treatment needs to be repeated once they've hatched. This means more nasty chemicals, and more discomfort for the child (or adult). That's why researchers at Germany's Fraunhofer Institute for Surface Engineering and Thin Films have developed an alternative, in the form of a comb that zaps the pests with cold plasma.
The crown-of-thorns starfish poses a major threat to the wellbeing of Australia's Great Barrier Reef. Wild, uncontrollable outbreaks over the past few decades have seen the pests multiply to devour vast amounts of coral, and as it stands there's little that can be done. One method conservationists have used to some effect is injecting them with ox bile, but researchers have now discovered that a simple dose of vinegar can do much the same job, promising to significantly cut the cost of an expensive battle to rid a World Heritage Site of this damaging pest.
If you've ever used tick medicine on your dog, then you're probably
aware of how toxic the stuff is. Well, it's used on cows too, and it can
end up in their meat, milk, or the surrounding environment.
Fortunately, however, scientists at the National University of Mexico
have developed a new type of tick treatment for cattle that is
reportedly much less toxic than what's currently used.
