Pediatric brain tumors preserve specific characteristics of the normal cells from which they originate — a previously unknown circumstance with ramifications for how tumor cells respond to treatment. This has been shown by Uppsala researcher Fredrik Swartling together with colleagues in the U.S., Canada and England in a study that was published today in the distinguished journal Cancer Cell. Every year, 80-90 children in Sweden are afflicted with brain tumors, a serious form of...

About 300 000 years ago humans adapted genetically to be able to produce larger amounts of Omega-3 and Omega-6 fatty acids. This adaptation may have been crucial to the development of the unique brain capacity in modern humans. In today's life situation, this genetic adaptation contributes instead to a higher risk of developing disorders like cardiovascular disease. The human nervous system and brain contain large amounts of polyunsaturated fatty acids, and these are essential for the...

There is a connection between phthalates found in cosmetics and plastics and the risk of developing diabetes among seniors. Even at a modest increase in circulating phthalate levels, the risk of diabetes is doubled. This conclusion is drawn by researchers at Uppsala University in a study published in the journal Diabetes Care. "Although our results need to be confirmed in more studies, they do support the hypothesis that certain environmental chemicals can contribute to the development of...

Eggs Of Enigmatic Dinosaur Discovered

An Argentine-Swedish research team has reported a 70 million years old pocket of fossilized bones and unique eggs of an enigmatic birdlike dinosaur in Patagonia. What makes the discovery unique are the two eggs preserved near articulated bones of its hindlimb. This is the first time the eggs are found in a close proximity to skeletal remains of an alvarezsaurid dinosaur, says Dr. Martin Kundrát, dinosaur expert from the group of Professor Per Erik Ahlberg at Uppsala...

Image 1 - Were European Neanderthals Long Gone Before Humans Arrived?

New research suggests Western European Neanderthals were likely to have been extinct long before humans arrived on the evolutionary scene. Long thought to be the birth place of Neanderthal evolution, Western Europe has been studied and researched by scientists and anthropologists to better understand our ancient forefathers. As these Neanderthals began to disappear around 30,000 years ago, anthropologists had estimated either climate changes or competition from early humans caused the...

European Neanderthals We Already Close To Extinction Before Arrival Of Modern Humans

New findings from an international team of researchers show that most Neanderthals in Europe died off around 50,000 years ago. The previously held view of a Europe populated by a stable Neanderthal population for hundreds of thousands of years up until modern humans arrived must therefore be revised. This new perspective on the Neanderthals comes from a study of ancient DNA published Feb 25 in Molecular Biology and Evolution. The results indicate that most Neanderthals in Europe died off...

In a recent study led by Uppsala University, the researchers compared the DNA of identical (monozygotic) twins of different age. They could show that structural modifications of the DNA, where large or small DNA segments change direction, are duplicated or completely lost are more common in older people. The results may in part explain why the immune system is impaired with age. During a person's life, continuous alterations in the cells' DNA occur. The alterations can be changes to the...
