Major epidemics such as the recent Ebola outbreak or the emerging Zika epidemic may be difficult to forecast because of our inability to determine whether individuals are uninfected or infected but not showing symptoms, according to a new study from the University of Cambridge. The finding emphasises the need to develop and deploy reliable diagnostic tests to detect infected individuals whether or not they are showing symptoms, say the researchers.
Scientists at the University 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.
The world of epigenetics – where molecular ‘switches’ attached to DNA turn genes on and off – has just got bigger with the discovery by a team of scientists from the University of Cambridge of a new type of epigenetic modification.
The fatter we are, the more our body appears to produce a protein that inhibits our ability to burn fat, suggests new research published in the journal Nature Communications. The findings may have implications for the treatment of obesity and other metabolic diseases.
New research shows the fluid found on insects’ feet does not help them adhere to vertical and inverted surfaces, as previously thought, but may in fact help them to unstick their feet more easily to allow greater control over their sticking power.
New research shows male lizards are more likely than females to be attacked by predators because the bright colours they need to attract a mate also make them more conspicuous to birds.
Delay mechanism within elegant brain circuit consisting of just five neurons means female crickets can automatically detect chirps of males from same species. Scientists say this example of simple neural circuitry could be “fundamental” for other types of information processing in much larger brains.
‘Bang! You’re Dead’, a 1961 episode of Alfred Hitchcock Presents, continues to surprise – but not just with the twist in its tale. Scientists at the University of Cambridge have used the programme to show that young people respond in a similar way to events, but as we age our thought patterns diverge.
Close-up film shows for the first time how ants use ‘combs’ and ‘brushes’ to keep their antennae clean27 Jul 2015
Using unique mechanical experiments and close-up video, Cambridge researchers have shown how ants use microscopic ‘combs’ and ‘brushes’ to keep their antennae clean, which could have applications for developing cleaners for nanotechnology.
A rare DNA base, previously thought to be a temporary modification, has been shown to be stable in mammalian DNA, suggesting that it plays a key role in cellular function.
