Formation of quadruple helix DNA tracked in live human cells for the first time

The biology of DNA must be rethink

23-Jul-2020

The formation of four-stranded DNA has been tracked in living human cells, allowing scientists to see how it works, and its possible role in cancer. DNA usually forms the classic double helix shape discovered in 1953 - two strands wound around each other. Several other structures have been formed ...

Sugar leads to early death, but not due to obesity

Study points out that the reduced life expectancy due to sugar consumption could have other causes than previously assumed

24-Mar-2020

We all know that consuming too much sugar is unhealthy. It increases our risk of developing metabolic disorders, such as obesity and diabetes, and can shorten our life expectancy by several years. It is widely believed that this reduction in lifespan is caused by metabolic defects. However, this ...

Tailor-made vaccines could almost halve rates of serious bacterial disease

Innovative study points the way to more effective vaccine design

14-Feb-2020

New research has found that rates of disease caused by the bacterium Streptococcus pneumoniae could be substantially reduced by changing our approach to vaccination. Researchers from the Wellcome Sanger Institute, Simon Fraser University in Canada and Imperial College London combined genomic ...

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 ...

Six fingers per hand

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 ...
