The tomato’s jet black colour stems from pigments in its skin which develop when exposed to sunlight.
Black tomatoes are being grown in Britain for the first time and they could have the potential to cure of cancer.
The fruit is among the first in the world to contain anthocyanins, an antioxidant believed to help fight cancer, diabetes and obesity.

flies (Tephritidae) are the most agriculturally important family of
flies. Some species are pests, together causing billions of dollars in
losses annually, whereas other species are beneficial biological control
agents of weeds. Fruit flies are also among the most attractive and
biologically interesting Diptera, having patterned wings and often
brightly colored and/or patterned bodies, which may be used in mimicry
of jumping spiders or wasps and in elaborate courtship and other
behaviors.
It is Evolution which make these fly to have spider
image on these wing to save themself from predictors. The image on the
wing is absolutely perfect,” says Dr Brigitte Howarth, the fly
specialist at Zayed University who first discovered G tridens in the
UAE. The species has been known since 1910, and is found in the Near and
Middle East, Asia, and Asia
On July 10th, 1913 the weather observer at Greenland Ranch in Death Valley, California recorded a high temperature of 134°F (56.7°C). This is the highest reliably recorded air temperature on Earth.
Death Valley's record temperature of 134 degrees Fahrenheit (56.7 degrees Celsius) - the hottest ever measured on Earth - was set exactly 100 years ago. But the tale of how the rocky expanse of California desert came to be known as the world's hottest place involves a lengthy stretch in the number two slot, a mission to set the record straight, and a scientist who disappeared amid a revolution.
The human brain consists of about one billion neurons. Each neuron forms about 1,000 connections to other neurons, amounting to more than a trillion connections. If each neuron could only help store a single memory, running out of space would be a problem. You might have only a few gigabytes of storage space, similar to the space in an iPod or a USB flash drive. Yet neurons combine so that each one helps with many memories at a time, exponentially increasing the brain’s memory storage capacity to something closer to around 2.5 petabytes (or a million gigabytes). For comparison, if your brain worked like a digital video recorder in a television, 2.5 petabytes would be enough to hold three million hours of TV shows. You would have to leave the TV running continuously for more than 300 years to use up all that storage.
The brain’s exact storage capacity for memories is difficult to calculate. First, we do not know how to measure the size of a memory. Second, certain memories involve more details and thus take up more space; other memories are forgotten and thus free up space. Additionally, some information is just not worth remembering in the first place.
The wings are translucent. Its most common English name is glasswinged butterfly, and which means "little mirrors". Indeed, the tissue between the veins of its wings looks like glass, as it lacks the colored scales found in other butterflies.The opaque borders of its wings are dark brown sometimes tinted with red or orange, and its body is dark in color.
The Liger is a hybrid cross between a male lion and a tigress.
Ligers enjoy swimming, which is a characteristic of tigers, and are very sociable like lions.Ligers typically grow larger than either parent species, unlike tigons which tend to be about as large as a female tiger. Males reach a total length of 3 to 3.5 m, meaning they are larger than large Siberian tiger males. Female ligers may also attain great size, weighing approximately 320 kg (705 lb) and reaching 3.05 m (10 ft) long on average.
