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.

Scientists in a spin over Doppler Shift discovery
Scientists at the Universities of Glasgow and Strathclyde have discovered rotational speed can be determined by measuring Doppler Shift - the same effect utilised in radar speed guns. Doppler Shift is a phenomenon everyone is aware of, if perhaps not by name, and is most often experienced by the sound of a siren from a police car or ambulance rising and falling in pitch as it passes by.

Date palm leaves show potential as building materials
Date palm leaves show potential as building materials
A collaborative project involving Imperial and the UAE is assessing the potential of date palm leaves as a renewable, low-carbon building material. Phoenix dactylifera, or the date palm tree, is perhaps best known for its sweet fruit but, as growers in the United Arab Emirates (UAE) have known for thousands of years, its leaves can also be used in construction.

Secrets of bee honeycombs revealed
The mystery of the hexagonal shape of honeycomb cells has been revealed by simple mechanics. The honeybee comb is a widely studied natural cellular structure. The rounded hexagonal shape of its cells has intrigued natural scientists and philosophers for millennia. They have suggested many explanations some of which would need the bees to have an uncanny ability ("forethought" according to Pappus of Alexandria in 4 AD) to perform mathematical calculations or the magical quality to measure lengths and angles.

Personality clue to ’wind turbine syndrome’
Public concern about new technology infrastructure like mobile phone masts has been shown to trigger reports of ill health.. and recently even the new 'green' technology of wind turbines has been blamed for medically unexplained non-specific symptoms. But now, for the first time, a study by psychologists, engineers and built environment experts at The University of Nottingham , has found no link between the 'measured' level of noise from small and micro wind turbines and reports of ill health.

Microswimmers hit the wall
Microswimmers hit the wall
" The results of a study published today (7 January) suggest that microbes 'feel' their way along a solid surface, much as a blindfolded person would move near a wall. Using high-speed microscopic imaging, University of Cambridge researchers have found that sperm cells accumulate at surfaces and algae move away from them as a result of between the surface and the cells' flagella or cilia - the hair-like appendages that propel cells through their fluid environment.

The detectives of corrosion
Corrosion costs the oil and gas industry billions of dollars every year, it can also have far reaching environmental consequences. But so far no one has managed to stop corrosion happening. A detective style research team based at The University of Nottingham Malaysia Campus are working closely with industry to investigate real world problems and are taking a forensic look at the nature of corrosion — particularly in the oil and gas sector.

South American cricket ears shown to rival human hearing
South American cricket ears shown to rival human hearing
Scientists studying a species of South American bush cricket with some of the smallest ears known have discovered it has hearing so sophisticated that it rivals our own. The study is the first to identify hearing organs in an insect that are evolutionary convergent to those of mammals. The HFSP and BBSRC -funded research, led by the scientists at the University of Bristol, show how the bush cricket's ( Copiphora Gorgonensis ) auditory system has evolved over millions of years to develop auditory mechanisms strikingly similar to those of humans, but using an entirely different machinery.

Perception of time
Perception of time
How people experience time may be affected by the way that they perceive cause and effect, new research by the University has shown. Marc Buehner of the School of Psychology examined how causal belief - understanding that one thing leads to another (for example flicking a switch and a light coming on) - influences time perception.

Former drivers help F1 teams get podium positions
Formula One teams are more likely to cross the finish line first if their boss is a former F1 driver, according to new research conducted by the University of Sheffield and the Cass Business School. The pioneering study shows putting money on teams like Red Bull and Sauber, which are headed by experts not general managers, is a wise move as former drivers and mechanics win twice as often as other types of F1 leaders.
