New Experiments Confirm That Neutrinos Travel Faster Than Light
New results show neutrinos still faster than light
One of the most staggering results in physics – that neutrinos may go faster than light – has not gone away with two further weeks of observations. The researchers behin
Neurons with hyperactive tendencies may help to explain the mysterious mechanisms that cause synaesthesia. The discovery could help develop treatments for other visual ano

Space. It separates you from me, one galaxy from the next, and atoms from each other. It is everywhere in the universe. But to most of us, space is nothing, an empty void. Well, it turns out space is not what it seems. From the passenger seat of a New York cab driving near the speed of light to a pool hall where billi

Paying for sex and 'playing dead' - the deceitful gift-giving spider
Male nursery web spiders (Pisaura mirabilis) prepare silk-wrapped gifts to give to potential mates. Most gifts contain insects, but some gifts are inedible pla
Scientists from around the world have completed a study that says harvesting the sun's energy in space can turn out to be a cost effective way of delivering the world’s needs for power in as little as 30 years. As important, the report says that orbiting power p

Biologists uncover a novel cellular proofreading mechanism
To make proteins, cells assemble long chains of amino acids, based on genetic instructions from DNA. That construction takes place in a tiny cellular structure called a ribosome, to which amino acids are delivered by transfer RNA (tRNA).
A team of researchers at EPFL, the University of Lausanne and the Salk Institute created super strong, marathon mice and nematodes by reducing the function of a natural inhibitor, suggesting treatments for age-related or genetically caused muscle degeneration are within reach.
Hi, Post any of your maths queries that you have in this board.

In rats, two genes each with two alleles (A,a and R,r) interact to produce the following phenotypes
In rats, two genes each with two alleles (A,a and R,r) interact to produce the following phenotypes: A_R_ : grey A_rr : yellow aaR_ : black aarr : cream These phenotypes require that another gene with the dominant allele C be present since cc individuals are albino. All genes assort independently. Two different albino lines were each
A dominant allele L results in short hair in guinea pigs; allele l results in long hair. Codominant alleles of another gene specify hair colour, such that C y C y = yellow, C y C w = cream and C w C w = white. Predict what phenotypic ratio you would expect in a dihybrid cross with these genes.
Does anyone have a paper on " drinking water and sanitation"
The paper should be written in the THIRD PERSON taking the individual out of the writing and avoiding pronouns such as I, we, my, our (first person) and you, yours, your, us, we (second person). You should deal with facts and not opinions, thus providing citations within your paper and on your reference page. Focus on the subject itself and not on your feelings about the subject. Th
