In Washington, religious groups are interest groups. Just like the National Rifle Association or the farm lobby, the bishops want their priorities to take precedence over everyone else’s — and their clerical garb gives their position gravitas. But in truth, the bishops’ claims to moral truth are just that — claims. Their religious vows do…
Astronomers have found black holes and supermassive black holes. But the discovery of a mid-size black hole could support the idea that supermassive black holes grow by eating others.
Mercury does not cause autism, another study now concludes. The levels of mercury in the urine of children with autism were no higher than urine mercury levels of children without the condition, the study from England found. The discredited idea that the form of mercury, called ethylmercury, sometimes used in vaccines may lead to autism…
Pygmy goats can develop “accents” as they grow older, according to scientists. The young animals, known as “kids”, are raised in groups or “creches” with goats of a similar age. Researchers found that when young goats mixed in these social groups their calls became more similar. The animals join an elite group of mammals known…
One of the most mind-blowing areas of quantum mechanics is entanglement: two or more particles separated in space can have physical properties that are correlated. A measurement performed on one particle will tell us the result of the same measurement taken on an entangled particle. Entanglement is important but difficult to study, both in terms…
The rogue proteins behind variant CJD, the human form of mad cow disease, have revealed their benign side. Prions, it seems, lie at the heart of a newly discovered form of near-instant evolution that provides life with a third way to adapt to potentially lethal environments. Crucially, it involves neither genetic nor epigenetic changes to…
Internal documents have been leaked from the Heartland Institute, a Chicago nonprofit think tank, showing its funding of leading skeptics of global warming and a plan to teach climate change skepticism in schools. An anonymous person leaked the documents to several publications and activists supporting the science of climate change. “The heart of the climate…
Scientists hunting the Higgs boson, the sub-atomic particle believed to have played a vital role in the creation of the universe, have decided to turn up the power in their Large Hadron Collider to try to prove its existence this year. The CERN research centre near Geneva wants to prove or disprove the existence of…
In an unlikely marriage of quantum physics and neuroscience, tiny particles called quantum dots have been used to control brain cells for the first time. Having such control over the brain could one day provide a non-invasive treatment for conditions such as Alzheimer’s disease, depression and epilepsy. In the nearer term, quantum dots could be…
Childhood abuse and maltreatment can shrink important parts of the brain, a new study of adults suggests. Reduced brain volume in parts of the hippocampus could help to explain why childhood problems often lead to later psychiatric disorders, such as depression, drug addiction and other mental health problems, the researchers say. This link could help…
