Giant leaps of evolution make cancer cells deadly

HOW does cancer do it? How does one little cell transform itself into an invader that rages out of control? Surprisingly abruptly, according to new results that are pointing the way to Darwinian-inspired treatments. When a cancer evolves the ability to metastasise, or invade multiple tissues in the body, it has to pull off several remarkable…

Exposure to Pesticides Results in Smaller Worker Bees

Exposure to a widely used pesticide causes worker bumblebees to grow less and then hatch out at a smaller size, according to a new study by Royal Holloway University of London. The research, published today in theJournal of Applied Ecology, reveals that prolonged exposure to a pyrethroid pesticide, which is used on flowering crops to…

Strange Ancient Fish Had Front And Back Legs

The closest known relative of the ancestors of limbed animals such as humans likely evolved the foundation for rear legs even before the move to land, researchers say. This ancestor may have even been able to walk underwater, they added. These findings reveal that a key step in the evolution of hind limbshappened in fish, challenging…

Fossil Pigments Reveal the Colors of Ancient Sea Monsters

During the Age of the dinosaurs, huge reptiles, such as mosasaurs and ichthyosaurs, ruled the seas. Previously, scientists could only guess what colours these spectacular animals had; however, pigment preserved in fossilised skin has now been analysed at SP Technical Research Institute of Sweden and MAX IV Laboratory, Lund University, Sweden. The unique soft tissue…

Florida’s mangroves are making a move north

From South Florida to St. Augustine, mangroves are making moves up Florida’s Atlantic coast, chewing up salt marshes in the latest indicator of global climate change. But scientists say the ecological consequences may not be harmful. “There are plenty of examples of climate change having a negative impact, but this is something very different,” said…

Why is bioinformatics important?

The greatest challenge facing the molecular biology community today is to make sense of the wealth of data that has been produced by the genome sequencing projects. Traditionally, molecular biology research was carried out entirely at the experimental laboratory bench but the huge increase in the scale of data being produced in this genomic era…

UV Light Makes Mushrooms Rich in Vitamin D

The dog days of summer are a distant memory and so are the long bright sunny days. But for many people, sunlight is an essential source of vitamin D. The human body needs vitamin D to maintain bone health and helps regulate the immune system. The ultraviolet light in sunlight actually converts cholesterol in your…

Numbers released by the Florida Fish and Wildlife Research Institute in St. Petersburg this week showed the number of dead…
