Why get a filling when you could print a new smile?

A new material printed onto teeth could help the approximately one in 10 people who suffer from dental sensitivity caused by worn enamel.

by Ethan Bilby Twinges. Painful teeth. About one in 10 people suffer from dental sensitivity caused by worn enamel. But rather than providing short-term solutions like special toothpastes or fillings, new techniques could print whole new layers of enamel onto teeth – or even stimulate the body to grow new ones. Dr Antonios Anastasiou wants to … Read more

Raising ocean literacy levels could protect marine environment

Getting people involved in local community projects can help them engage with how the oceans are changing.

Hundreds of kilometres away from any sea, ocean or sandy beach, students from countries such as the Czech Republic have been discovering their connection with the marine world. While Europe’s landlocked states are understandably not so preoccupied with seas and oceans, camps run by members of Ecsite — the European network of science centres and museums — … Read more

Oil-loving microbes could gobble up slicks and spills

The lingering oil slick from DeepWater Horizon was imaged off the Mississippi Delta on May 24, 2010.

Spills of crude oil that devastate huge areas of the oceanic environment could be cleaned up by naturally occurring microorganisms. It’s one application of new research into how bacteria break down oil, which could also help oil companies assess the quality of new reserves. In 2010, the Deepwater Horizon oil spill released around 5 million … Read more

Sea anemone sting cells could inspire new drug-delivery systems

A group of creatures known as cnidarians, which includes sea anemones, are the only animals that inject venom via sting cells.

A multi-stage genetic process for the formation of sting cells in sea anemones could inspire a new way of delivering drugs into the human body. It’s part of a field of work that looks at how venom and the way it’s produced in animals could be used to create life-saving treatments for humans. Dr Kartik … Read more

Life scientists unite to close EU’s innovation gap

Research excellence relies not only on funding but also on the right governance and culture, according to experts.

Nepotism, a lack of transparency and poor governance are among some of the challenging conditions faced by researchers in Central and Eastern Europe, according to a consortium of life scientists who have set up a project to raise the level of research excellence in those countries. ‘The importance of institutions in providing a favourable environment … Read more

Arsenic and permafrost microbes help hunt for life on Mars

Bacteria survive in the harsh conditions of the Andean lakes of Argentina among high concentrations of arsenic.

Studying environments that are similar to Mars, and their microbial ecosystems, could help prepare biologists to identify traces of life in outer space. In some of the most remote areas of our planet, scientists are examining how life can persist in the form of tiny microbes that inhabit a niche that would be fatal to … Read more
