Early-stage embryos with abnormalities may still develop into healthy babies

29 March 2016

Abnormal cells in the early embryo are not necessarily a sign that a baby will be born with a birth defect such as Down’s syndrome, suggests new research carried out in mice at the ̽��ֱ�� of Cambridge. In a study published today in the journal Nature Communications, scientists show that abnormal cells are eliminated and replaced by healthy cells, repairing – and in some cases completely fixing – the embryo.

‘Clogged-up’ immune cells help explain smoking risk for TB

24 March 2016

Smoking increases an individual’s risk of developing tuberculosis (TB) – and makes the infection worse – because it causes vital immune cells to become clogged up, slowing their movement and impeding their ability to fight infection, according to new research published in the journal Cell.

Embryo development: Some cells are more equal than others even at four-cell stage

24 March 2016

Genetic ‘signatures’ of early-stage embryos confirm that our development begins to take shape as early as the second day after conception, when we are a mere four cells in size, according to new research led by the ̽��ֱ�� of Cambridge and EMBL-EBI. Although they seem to be identical, the cells of the two day-old embryo are already beginning to display subtle differences.

Researchers identify when Parkinson’s proteins become toxic to brain cells

14 March 2016

Observation of the point at which proteins associated with Parkinson’s disease become toxic to brain cells could help identify how and why people develop the disease, and aid in the search for potential treatments.

Colonies of human naïve embryonic stem cells grown on mouse feeder cells

Scientists develop very early stage human stem cell lines for first time

04 March 2016

Scientists at the ̽��ֱ�� of Cambridge have for the first time shown that it is possible to derive from a human embryo so-called ‘naïve’ pluripotent stem cells – one of the most flexible types of stem cell, which can develop into all human tissue other than the placenta.

Highway to addiction: how drugs and alcohol can hijack your brain

25 February 2016

̽��ֱ��discovery of a brain circuit ‘shortcut’ could explain why some addicts unintentionally relapse, and suggests that a shift in focus for therapies might help those who want to stay off drugs.

Children aren’t active enough in winter, say Cambridge researchers

23 February 2016

Children should be given more support to enable them to be more active during the winter, particularly at weekends, say researchers from the ̽��ֱ�� of Cambridge. Their call comes in response to their findings that children are less active and spend more time sitting in autumn and winter compared to other times of the year.

Schizophrenia and the teenage brain: how can imaging help?

17 February 2016

Adolescence is a dangerous time for the onset of mental health problems. Advances in brain imaging are helping to picture how neural changes in these crucial years can lead to chronic debilitating mental illness.

Spinal injury and ‘biorobotic control’ of the bladder

16 February 2016

There are many challenges facing people with spinal cord injury – and walking again is often the least of their problems. Cambridge research could help patients take control of their lives once more.

̽��ֱ��amazing axon adventure

05 February 2016

How does the brain make connections, and how does it maintain them? Cambridge neuroscientists and mathematicians are using a variety of techniques to understand how the brain ‘wires up’, and what it might be able to tell us about degeneration in later life.
