AI-powered barcode unmasks 'zombie cells' in aging tissue

As we age, some of the cells in our body enter a state of senescence, in which they stop dividing but do not die. Those senescent cells can contribute to age-related disorders such as cancer, tissue degeneration and inflammatory diseases. In an advance that could lead to better ways to diagnose and treat those diseases, MIT researchers have developed a noninvasive way to detect biomarkers of senescence. Their method is based on Raman microscopy, which can reveal the biochemical composition of cells without harming them.

Can Maths Combat Terrorism?

Dr Hannah Fry investigates the hidden patterns behind terrorism and asks whether mathematics could be used to predict the next 9/11. When computer scientists decided to study the severity and frequency of 30,000 terrorist attacks worldwide, they found an distinctive pattern hiding in the data. Even though the events spanned 5,000 cities in 187 countries over 40 years, every single attack fitted neatly onto a curve, described by an equation known as a 'power law'. Now this pattern is helping mathematicians and social scientists understand the mechanisms underlying global terrorism. Could these modelling techniques be used to predict if, and when, another attack the size of 9/11 will occur?

New Space to Fly

As our skies become more crowded Jack Stewart examines the long awaited modernisation of air traffic control. With traffic predicted to reach 17 million by 2030 more flights will mean more delays. For many a new approach to controlling flights is long overdue since aircraft still follow old and often indirect routes around the globe, communication between the ground and air is still by VHF radio, and any flexibility is heavily constrained by a fragmented airspace operated by many national authorities. Jack Stewart examines how aviation technologists have come up with a radical solution. It enables pilots, once airborne, to choose their own route. 'Free Routing', it is argued, will allow more direct flights, no planes to be caught up in holding patterns, reduced fuel emissions and flights departing and arriving on time. Crucially, free routing will enable a tripling of flights than currently we are capable of controlling. But will the ability of pilots to choose their own routes increase the risk of collision? Researchers argue it will in fact produce even safer skies. Jack Stewart visits NATS air traffic control centre that annually looks after the safety of over two million British airspace to hear how such a system could evolve. Jack finds out how free routing could work from the engineers at Indra UK – who are trialling such a system in airspace controlled by the NATS Prestwick air traffic control centre. In a new approach they are turning 'reactive' air traffic control into a more strategic approach with computer designed flight trajectories utilising much of the currently underused satellite navigation that is fitted on modern aircraft. It will enable aircraft to be safely spaced closer together and at the same time predict potential 'conflicts' of spacing much fur

Vagus Nerve

Many people are living with chronic diseases such as rheumatoid arthritis and inflammatory bowel conditions in which the body attacks itself. Although drug treatments have improved over recent years they do not work for everyone and can have serious side effects. Now researchers such as neurologist Dr Kevin Tracey of the Feinstein Institute for Medical Research, and rheumatologist professor Paul-Peter Tak of Amsterdam University, are trying a new approach to improving the lives of these patients. They are firing electrical pulses along the vagus nerve, a major nerve that connects the brain with all the organs. The technology to do this has been around for some decades as stimulating the vagus nerve has been used to help people who have epilepsy that is not controlled with drugs since the 1990s. Gaia Vince talks to these pioineers of this new field of research. And, she hears how there may be ways of improving the tone of the vagal nerve using meditation.(Image: Vagus Nerve Stimulation.
