A rare condition, known as situs inversus, is when a person has their major organs mirrored from their normal positions. So, for example, the heart would be on the right side of the body, or the liver and gall bladder are on the left side. It is a congenital condition (meaning it's tied to your genetics) that affects 1 in 20,000 people - including Spanish-born singer Enrique Iglesias.
Situs inversus is generally an autosomal recessive genetic condition, although it can be X-linked or found in identical "mirror image" twins.
According to a new study published in the journal PLOS One, it was found that identical twins are equally attractive to mosquitoes than fraternal - or non-identical - twins. This correlation lead researchers to conclude that mosquitoes might be making preferential choices based on differences in our DNA.
What causes this preferences? While it may be nice to believe that that mosquitoes are attracted to "sweeter blood", it's not true at all. Female mosquitoes - the ones that bite, in order to get protein necessary for egg development - are actually drawn to us by chemical signals related to body odour. [ ... ]
Thanks to a shipwreck in the Baltic Sea, we now know what 170-year-old champagne (kept in near perfect aging conditions) tastes like! Tasters described the aroma of the champagne - likely the oldest ever imbibed - as spicy, smoky, and leathery.
At 9% alcohol by volume, it was significantly less alcoholic than the modern version, which contains about 12% alcohol, likely due to a less efficient fermentation process. The researchers also found traces of chemicals from wood, suggesting that the champagne was fermented in barrels.
Eucalyptus deglupta, commonly called rainbow eucalyptus, is a very large, fast-growing, broadleaved evergreen tree that is native to moist humid tropical forested areas with high rainfall in New Guinea, Indonesia and the Philippine Islands (Island of Mindanao).
It is perhaps best noted for its smooth orange-tinted trunk bark which peels in summer to reveal a unique and sometimes stunning multi-colored bark (as described by the common name of rainbow eucalyptus) consisting of streaks of pale green, red, orange, gray and purple-brown. [ ... ]
The lake Leitisvatn/Sørvágsvatn sits about 30 metres above sea level.
The Faroe Islands are an archipelago between the Norwegian Sea and the North Atlantic Ocean, approximately halfway between Norway and Iceland, 320 kilometres (200 mi) north-northwest of mainland Scotland. The area is approximately 1,400 km2 with a 2010 population of 50,000.
On the Mediterranean island of Cyprus, you might be lucky to find a black flamingo. Normal flamingoes are born white and grey, and turn their iconic shade of pinky orange around the age of two, as a result of the high carotenoid content of the algae and crustaceans that they eat.
Experts believe that this individual (and potentially the other bird spotted in Israel) has a genetic condition that causes it to overproduce melanin, changing its feathers to black.
Belonging to the class Arachnida, Amblypygids, also known as whip spiders or tailless whip scorpions, form a separate order of arachnids alongside the spiders, scorpions, and others. The name "amblypygid" means "blunt rump", a reference to a lack of the flagellum ("tail"). They are harmless to humans, and possess no silk glands or venomous fangs. They rarely bite if threatened, but can grab fingers with pedipalps (thorn-like appendages), resulting in thorn-like puncture injury.
