New way to sustainably make chemicals by copying nature's tricks

08-Jan-2020

Researchers have copied the way organisms produce toxic chemicals without harming themselves, paving the way for greener chemical and fuel production. The new technique, pioneered by Imperial College London scientists, could reduce the need to use fossil fuels to create chemicals, plastics, ...

'Poisoned arrowhead' used by warring bacteria could lead to new antibiotics

07-Oct-2019

A weapon bacteria use to vanquish their competitors could be copied to create new forms of antibiotics, according to Imperial College London research. Researchers have uncovered a novel weapon in the arsenal of bacteria that works in a similar way to common antibiotics. By discovering the ...

A congenital additional finger brings motor advantages

05-Jun-2019

Polydactyly is the extraordinary condition of someone being born with more than five fingers or toes. In a case study published in Nature Communications, researchers from the University of Freiburg, Imperial College London, the University Hospital of Lausanne, and EPFL have for the first time ...

Aspirin cuts heart attack risk but increases chance of dangerous bleeding

24-Jan-2019

Regular aspirin should not be recommended for preventing heart attack and stroke in people without cardiovascular disease. The researchers, from Imperial’s National Heart and Lung Institute and King's College London, analysed 13 clinical trials – involving more than 164,000 participants – that ...

New materials could 'drive wound healing' by harnessing natural healing methods

09-Jan-2019

Materials are widely used to help heal wounds: Collagen sponges help treat burns and pressure sores, and scaffold-like implants are used to repair bones. However, the process of tissue repair changes over time, so scientists are developing biomaterials that interact with tissues as healing takes ...

Bacterial 'sleeper cells' evade antibiotics and weaken defense against infection

How bacterial persister cells manipulate our immune system

11-Dec-2018

New research, from scientists at Imperial College London, unravels how so-called bacterial persister cells manipulate our immune cells, potentially opening new avenues to finding ways of clearing these bacterial cells from the body, and stopping recurrence of the bacterial infection. The latest ...

A toxic bullet involved in bacterial competition

23-Nov-2018

A bacterial toxin that allows an infectious strain of bacteria to defeat its competitors has been discovered by Imperial College London scientists. The finding provides a better understanding of the mechanisms behind bacterial warfare, which is the first step for the design of improved treatments ...

Blood test could detect kidney cancer up to 5 years earlier

14-Aug-2018

Scientists have discovered that a marker in the blood could help predict the risk that a person will develop kidney cancer. The study, supported by Cancer Research UK,examined the blood of 190 people who went on to develop kidney cancer, compared to 190 controls who did not. The teamfound that ...

Immune cells can switch from ‘gang members’ to ‘police officers’

12-Jul-2018

When the immune system overreacts, as in an allergic reaction, cells causing trouble can change into cells that dampen the reaction. Learning to control the mechanism behind the switch could be used to make more effective immunotherapies, say the authors of the new study, led by Imperial College ...

Bacteria can 'divide and conquer' to vanquish their enemies

04-Jul-2018

Some bacteria can release toxins that provoke their neighbours into attacking each other, a tactic that could be exploited to fight infections. Bacteria often engage in 'warfare' by releasing toxins or other molecules that damage or kill competing strains. This war for resources occurs in most ...
