More than 500,000 people in the United States die each year of cancer-related causes and a new study has identified the mechanism behind one of the most common mutations that help cancer cells replicate limitlessly.
Approximately 85 percent of cancer cells obtain their limitless replicative potential through the reactivation of a specific protein called telomerase (TERT). Recent cancer research has shown that highly recurrent mutations in the promoter of the TERT gene are the most common genetic mutations in many cancers, including adult glioblastoma and hepatocellular carcinoma.
A study presented at the European Congress of Endocrinology in Dublin suggests that some men suffering from testosterone deficiency may be missed under current clinical guidelines, while others are misdiagnosed with testosterone deficiency.
Anna Reusch, a doctoral student at ETH Zurich's Geological Institute, was making a routine research vessel run on Lake Neuchâtel when she noticed an unusual shape on the control panel screen.
At a depth of over 100 mettrs, she found something no one had ever detected before: a crater measuring 10 meters deep and 160 meters in diameter.
Reusch investigates the sediment in the lakes on the western Swiss Plateau for traces of past earthquakes, which involves taking high-resolution measurements of the floor of Lake Neuchâtel to find evidence of tectonically active zones that could trigger major earthquakes. The period Reusch is looking at is geologically speaking very recent: sometime in the past 12,000 years.
Nuclear power is sometimes described as being free of greenhouse gas emissions, and that’s true of the nuclear fission reactions themselves. But here is a list of all the stages of the nuclear power cycle at which greenhouse gases are emitted: uranium mining, uranium milling, conversion of uranium ore to uranium hexafluoride, uranium enrichment, fuel fabrication, reactor construction, reactor decommissioning, fuel reprocessing, nuclear waste disposal, mine site rehabilitation, and transport throughout all stages.-->
In 2003, while French youth protested American imperialism, 14,000 mostly elderly people were allowed to die in a heat wave. Heat waves kill a lot more people, it is believed, except they don't. Instead, an analysis of 74 million deaths in 384 locations across Australia, Brazil, Canada, China, Italy, Japan, South Korea, Spain, Sweden, Taiwan, Thailand, UK, and the USA found that cold weather kills about 20 times as many people as hot weather.
Researchers have confirmed strong warming in the upper troposphere, known colloquially as the tropospheric hotspot, long expected as part of the global warming hypothesis.
Though the tropospheric hotspot appears in many global climate models, the inability to detect it has been used to suggest climate change is not occurring as a result of increasing carbon dioxide emissions.
Our belief in evil influences our feelings about capital punishment, according to Donald Saucier, associate professor of psychology at Kansas State University and Russell Webster at St. Mary's College of Maryland.
They drew their conclusion after about 200 participants were given a summary of a case in which a murderer confessed to his crime. They then asked each participant about his or her support for different types of sentences, such as jail time with community service, jail time with the opportunity for parole, jail time without the possibility for parole and other options.
Our solar system started as a disk of microscopic dust, gas, and ice around the young Sun and the amazing diversity of planets, moons, asteroids, and comets came from this primitive dust.
NASA's Stardust mission has returned to Earth with samples of comet Wild 2, a comet that originated outside the orbit of Neptune and was subsequently kicked closer to Earth's orbit in 1974 when Jupiter's gravity altered Wild 2's orbit.
