Mammals can generate their own body heat and control their body temperature. This process is known as endothermic or warm-blooded. Scientists believe that may be the reason why mammals tend to dominate almost everything ecosystem . Warm-blooded mammals are more active than cold-blooded animals. They can live in different environments, from frozen poles to boiling deserts. And they breed faster. Soft tissue that will provide information about being warm or cold blooded is rare preserved in fossil . So paleontologists, or experts in the study of fossils, don’t know exactly when mammals evolved and turned into warm-blooded creatures. A group of scientists tried to answer that question in a study recently published in Natural . Ricardo Araújo is a paleontologist at the University of Lisbon. Araújo and a group of researchers proposed that the shape and size of inner ear structures called canals could be used to study body temperature. The movement of fluid through the ear canal ...

This month, two rockets were heard to be launched from Australia, carrying out experiments to determine whether the ultraviolet light emitted by stars from the Alpha Centauri system is detrimental to potential life on planets around them. The study will also reveal how typical – or abnormal – the sun is. Alpha Centauri consists of two main stars, Alpha Centauri A and Alpha Centauri B (which form a binary pair), as well as a third star, Proxima Centauri, which is only 4.3 light-years away. While no planets have been detected positively orbiting Alpha Centauri A or B, if they do exist, the ultraviolet radiation from their stars may have a significant impact on whether or not they support life. The right amount of ultraviolet light can break down simple organic molecules, such as methane, prompting molecular fragments to reshape the more complex molecules necessary for life. On the other hand, too much ultraviolet could separate out water vapor, make it escape from the plane...

By Kalli Spencer After a radical prostatectomy there is always a risk that the cancer may recur. Certain factors can increase this risk such as high grade features in the initial biopsy specimen, cancer that may have emerged from the prostate capsule, micrometastases (cancer that cannot be detected by any imaging), technical difficulties in surgery or no explanation at all. in addition to the genetic makeup of cancer in a particular individual that gives it a predisposition to grow and invade. In its quest for survival, cancer develops several mechanisms to evade the immune system and may even counter the effects of treatment. The genetics behind this are still largely unknown. But scientists are studying it and success has been seen in other tumors such as colon and stomach cancer. A team from the University of Wisconsin in the United States has developed a unique diagnostic test that utilizes artificial intelligence to detect genetic disorders and determine which patients’...
