Parts of our genetic programs that determine programmed cell death in plants and animals are actually evolutionarily related and function in a similar way, according to an article in Nature Cell Biology.
Research has previously believed that animals and plants developed different genetic programs for cell death.
Children in english-speaking, letter-driven languages are diagnosed with dyslexia more commonly than those in Asia so is it a function of our alphabet?
English dyslexia consists of a 'phonological disorder', meaning that people with the condition have trouble detecting or manipulating the sound structure of oral language, which in turn leads to problems in mapping speech sounds onto letters
Chinese-speaking children get a form of dyslexia but the disorder is distinctly different, and perhaps more complicated and severe, than that of English speakers. Those differences can even be seen in the brain and in the performance of Chinese children on visual and oral language tasks, according to a report in Current Biology.
40,000 or so spiders have been described, all of which have been thought to be strict predators that feed on insects or other animals, trapping their prey in elaborate webs or hunting them down directly. But researchers have now found one exception to this rule, a neotropical jumping spider known as Bagheera kiplingi and the first instance known to science of a spider that dines primarily on vegetarian fare, according to a report published in Current Biology.
The spiders' veggie option of choice is so-called Beltian bodies, specialized leaf-tip structures produced by acacia shrubs. The Beltian bodies normally serve as a food reward for ants that live in hollow spines of the acacia and act as the plants' "bodyguards."
If you like big scallops for dinner, we have good news - ocean warming, at least in UK waters, has increased stocks of the great scallop Pecten maximus, according to a study published in Marine Biology.
But further rises in water temperatures could have the opposite effect on scallops and better management of these fisheries may be needed to protect sensitive seabed habitats, according to the analysis of 20 years of data by scientists at Bangor University and the Universities of York and Liverpool.
A new thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden says elite athlete injuries could be reduced if players perform injury-preventing strength training with supervision. About half of Swedish elite volleyball players suffer at least one injury per season.
University of Utah engineers have shown off a wireless network of radio transmitters that can track people moving behind solid walls, which may help police grab intruders or rescue hostages and might also help retail marketing and border control.
Their method uses radio tomographic imaging (RTI), which can "see," locate and track moving people or objects in an area surrounded by inexpensive radio transceivers that send and receive signals. People don't need to wear radio-transmitting ID tags.
