Commonly known as blue-green algae, toxic cyanobacteria can harm humans and wildlife alike when their populations soar in lakes or rivers. A newly developed sponge, however, could soon help bring such harmful algal blooms under control.

A nice strong cup of espresso is great for clearing the cobwebs out of the brain first thing in the morning. It might also be good for clearing Alzheimer's-causing protein tangles away too if lab tests hold up in further research.

When testing for infections such as strep throat, saliva sampling is often used as a less invasive alternative to taking throat swabs. Collecting that saliva could soon be easier than ever, by using a lollipop to do the job.

The tiny bubbles or effervescence are a big part of the attraction of sipping a glass of champagne but, over time, it loses its fizz. A new study has found that size is everything when it comes to keeping your champagne bubbly for longer.

Most wound dressings simply cover the injury and perhaps also kill harmful bacteria. The PAINT system goes much further, as it incorporates a pen that could one day allow doctors to paint a gelatinous healing ink right into wounds.
-
While many goods simply have to be kept frozen until use, some – such as certain vaccines – will break down even if they get warmed but remain frozen. An inexpensive new technology could alert people to the fact that this has happened.

Indian scientists have developed a groundbreaking method to extract keratin and melanin from discarded hair, opening up possibilities for their use in wound dressings and sunscreens.

The longer it takes to brew a batch of beer, the greater the chances of microorganisms getting in and ruining the whole thing. In order to speed up and simplify the process, scientists have developed tiny BeerBots.

While reusing cutlery is always better than discarding it, most people aren't going to be packing a knife and fork whenever they grab some fast food. Scientists have thus designed a plant-and-wood-based material that dissolves once broken apart.

Although it is possible to control devices using brain waves, doing so involves having electrodes and conductive gel applied to one's head. Now, however, scientists have developed a new type of "dry" electrode – and it's been used to control a robot.

Most three-dimensional glass objects are produced via either a molding, blowing or 3D-printing process. Chinese scientists, however, have devised a technique of folding such items into shape – and it has some key advantages over other methods.

Wouldn't it be nice if medication could be injected without using a painful needle, and if that medication could be stored at room temperature? Well, it turns out that MOF-Jet technology may make both things possible.
