Antifreeze fish inspire new cryoprotectants for human cells and tissues

The idea of cryogenically freezing a person to preserve their body until many years into the future has long been a staple of science fiction stories. However, the need to reliably store biological materials such as cells or tissue is a common concern for scientific research and, increasingly, for society too.

More bacteria are becoming resistant to antibiotics – here's how viruses and vaccines could help

Antibiotic resistant bacteria are killing more people each year, but scientists are turning to their natural virus predators to treat infections, as well as new vaccines to prevent disease.

How we prepare for an ‘age of pandemics’

The current pandemic caught the world off guard but there are more to come, and we need to work out how to better prepare for and respond to future crises before they occur, an audience at the European Commission’s annual Research and Innovation Days conference has heard.

How vulnerable groups were left behind in pandemic response

Viruses like Covid-19 make no distinction between those they infect. They should in theory cause disease in the rich just as they do the poor and pay no heed to social status or cultural background. But in practice the pandemic has widened the gulf between vulnerable groups and other populations in Europe rather than helping to level out inequalities in society, researchers warn.

Virus cocktails and ice guns could help to tackle food poisoning risk

Harmful bacteria found in chickens that can cause food poisoning outbreaks and devastate poultry flocks could be better controlled with innovative new solutions being developed by researchers.

Nanorobots could target cancers and clear blood clots

Tiny nano-sized robots and vehicles that can navigate through blood vessels to reach the site of a disease could be used to deliver drugs to tumours that are otherwise difficult to treat.

Q&A: How to track down a new virus – and link it to disease

Finding new viruses is easy – the hard part is understanding which ones cause disease, says Dr Lia van der Hoek, a virologist from the Amsterdam UMC, the Netherlands, who discovered a human coronavirus called NL63, in 2003.

How chemists are building molecular assembly lines

Four huge robot arms surround the gleaming metal shell of what will soon be a top-of-the-range automobile. They jerk into life, attaching the bonnet, the wing mirrors, and other panels. It’s the kind of precision operation you can find at car factories around the world these days. But here’s a question worth considering: could we pull off a feat like this only about a billion times smaller?

Foldable, organic and easily broken down: Why DNA is the material of choice for nanorobots

Only in cancer medicine do we aim to attack and kill legions of our own cells. But healthy bystander cells often get caught in deadly crossfire, which is why cancer treatments can cause severe side effects in patients.

Five things to know about: Mixing and matching coronavirus vaccines

Amid global vaccine rollouts, with nearly 1.2 billion doses currently administered, some countries have recommended a mixed-dose approach where a first prime shot is followed by a booster of a second type.
