Plants use latex to harm and heal
Plants use latex to harm and heal
Plants use natural latex in different ways, to help poison insects or rapidly heal wounds, a new study has found. Scientists from the Universities of Oxford, Sheffield and Freiburg tested latex samples from two different types of plant. They found that Euphorbia plants use slow-drying latex to keep insects in with their noxious sap whereas Ficus plants, such as the weeping fig, use fast-drying latex to seal wounds more quickly.

Proteins in their natural habitat
Proteins in their natural habitat
Proteins which reside in the membrane of cells play a key role in many biological processes and provide targets for more than half of current drug treatments. These membrane proteins are notoriously difficult to study in their natural environment, but scientists at the University of Oxford have now developed a technique to do just that, combining the use of sophisticated nanodiscs and mass spectrometers.

Study of Brazilian Amazon shows 50,000 km of road was built in just three years
Study of Brazilian Amazon shows 50,000 km of road was built in just three years
Nearly 17,000 kilometres of road were built in the Brazilian Amazon rainforest every year between 2004 and 2007. Although road-building is a major contributor to deforestation and habitat loss, the way in which road networks develop is still poorly understood. A new study is among the first to measure the number of roads built in a rainforest ecosystem over an extended period of time.

Dopamine dysfunction is not the main cause of Attention Deficit Hyperactivity Disorder (ADHD)
Research suggests that the main cause of the disorder may lie instead in structural differences in the grey matter in the brain. These findings question the previously accepted view that major abnormalities in dopamine function are the main cause of ADHD in adult patients. Professor Trevor Robbins A new Cambridge study questions previous suggestions that attention deficit hyperactivity disorder (ADHD) is the result of fundamental abnormalities in dopamine transmission, and suggests that the main cause of the disorder may lie instead in structural differences in the grey matter in the brain.

Smart neurons: single dendrites can perform computations
Smart neurons: single dendrites can perform computations
When you look at the hands of a clock or the streets on a map, your brain is effortlessly performing computations that tell you about the orientation of these objects. New research by UCL scientists has shown that these computations can be carried out by the microscopic branches of neurons known as dendrites, which are the receiving elements of neurons.

New research gives insight into how “Living Stones” adapt to extreme conditions
Research by scientists at the University of Sheffield has given new insight on how some plants adapt to extreme conditions which could help in the future development of efficient crops. The study was carried out on plants native to southern Africa known as "Living Stones", or Lithops. These little succulents survive in the blazing deserts and rocky ground of southern Africa by blending in with surrounding pebbles to avoid being eaten and by burying themselves underground.

Brain imaging may pinpoint loss of perception under anaesthetic
Oxford University researchers have shown that measuring a type of brain activity in an individual under anaesthetic offers the clearest picture yet of degrees of perceptual awareness in the brain while they are anaesthetised. The research could lead to the first personalised method for administering appropriate doses of anaesthetic during operations and potentially reduce the risks associated with being under a general anaesthetic.

Plants tell the time
Plants use sugars to tell the time of day, according to research published in Nature today. Our research shows that sugar levels within a plant play a vital role in synchronizing circadian rhythms with its surrounding environment Alex Webb Plants, like animals, have a 24 hour 'body-clock' known as the circadian rhythm.

Plant scientists have been studying wrong plant
Scientists have misunderstood one of the most fundamental processes in the life of plants because they have been looking at the wrong flower, according to University of Leeds researchers. Arabidopsis thaliana —also known as thale cress or mouse-ear cress—grows abundantly in cracks in pavements all over Europe and Asia, but the small white flower leads a second life as the lab rat of the plant world.

Genetic disease which causes recurrent respiratory infections
We believe that now many more APDS patients will be identified all over the world Sergey Nejentsev Cambridge scientists have discovered a rare genetic disease which predisposes patients to severe respiratory infections and lung damage. Because the scientists also identified how the genetic mutation affects the immune system, they are hopeful that new drugs that are currently undergoing clinical trials to treat leukaemia may also be effective in helping individuals with this debilitating disease.

Maths study of photosynthesis clears the path to developing new super-crops
How some plant species evolved super-efficient photosynthesis had been a mystery. Now, scientists have identified what steps led to that change. Around three per cent of all plants use an advanced form of photosynthesis, which allows them to capture more carbon dioxide, use less water, and grow more rapidly.
