A book that criticizes alternative medicine to treat conditions that have names but no criteria is controversial - because it runs up against a supplement and alternative medicine enabled by governments that believe science can't be trusted
Do you feel like nutritionists are always changing their minds? Do you want science-based information about diet but don’t know whom or what to believe?If you’re nodding in agreement, you’re not alone: More than 80% of Americans are befuddled.Yet it’s a lament that’s getting quite tiring – if you’re a nutrition scientist, that is. So much so that I refocused my career to shine scientific light on today’s critical food conversations, which have profound impacts on public health and the environment. My mantra: From farm to fork, what we eat matters.
Most people use toothbrushes, toothpaste and dental floss to clean their teeth, but their use is by no means universal. Many indigenous groups, as well as people in developing countries, use traditional techniques to clean their teeth. Some of these techniques are more effective than others. Many people in the Middle East, and some parts of South and Southeast Asia, use twigs from the arak tree (known as miswak) to clean their teeth. They fray the end of the twig, dampen the resulting bristles with water or rosewater and then rub the bristles against their teeth (see video below). The wood of the arak tree (Salvadora persica) has a high concentration of fluoride and other antimicrobial components that prevent tooth decay.
From the Trump administration’s Muslim travel ban to its family separation policy, many Americans object to the White House’s hardline immigration policies as a historical aberration out of sync with U.S. values.Having explored the evolution of these policies and their consequences as both a practitioner of immigration law and scholar of U.S.-Latin American relations, I disagree.
Many people who are old enough to have experienced the first moon landing will vividly remember what it was like watching Neil Armstrong utter his famous quote: That’s one small step for a man, one giant leap for mankind”. Half a century later, the event is still one of the top achievements of humankind. Despite the rapid technological advances since then, astronauts haven’t actually been back to the moon since 1972.This seems surprising. After all, when we reflect on this historic event, it is often said that we now have more computing power in our pocket than the computer aboard Apollo 11 did. But is that true? And, if so, how much more powerful are our phones?
With Alex Trebek’s recent announcement that his pancreatic cancer is in remission, many people have wondered if this difficult cancer is now easier to treat. Pancreatic cancer remains a major cancer killer, but advances are happening.As a medical oncologist who specializes in treating and studying pancreatic cancer, I’ll try to provide insights, including some from the American Society of Clinical Oncology (ASCO) meeting now underway.
I work in the field of bioprinting, where the aim is to build biological tissues by printing living cells into 3D structures.Last month I found my Facebook news feed plastered with an amazing story about “the first 3D printed heart using a patient’s own cells”. A video showed a beautiful, healthy-looking heart apparently materializing inside a vat of pinkish liquid.
Australia has changed in many ways over the past two decades. Rising house prices, country-wide improvements in education, an aging population, and a decline in religious affiliation, are just some of the ways it has changed. At the same time, political power has moved back and forth between the two major parties. How much can we attribute changes in political power to changes in who we are? Quite a lot, as it turns out.Finding the ‘average’ electorateWe analyzed election results from 2001 to 2016 and mapped them against data from the census to see how socio-demographic characteristics influence voting patterns, and how this has changed over time.
In the Chinese science fiction film The Wandering Earth, recently released on Netflix, humanity attempts to change the Earth’s orbit using enormous thrusters in order to escape the expanding sun – and prevent a collision with Jupiter. The scenario may one day come true. In five billion years, the sun will run out of fuel and expand, most likely engulfing the Earth. A more immediate threat is a global warming apocalypse. Moving the Earth to a wider orbit could be a solution – and it is possible in theory.
Biogen recently announced that it was abandoning its late stage drug for Alzheimer’s, aducanumab, causing investors to lose billions of dollars. They should not have been surprised.
Testosterone is the main sex hormone in men. It’s best known for its role in the development of male sexual characteristics and physical features, but there are also many surprising and lesser known functions of testosterone that make it an important hormone in health and disease. Identifying whether someone has too much or too little testosterone can predict future diseases and even treat them. But knowing what is high, low or normal for an individual isn’t straightforward.
These days, anybody with an internet connection can be a publisher.That doesn’t make everybody a journalist.This distinction has become more important than ever in light of two recent events.
Surveys show that on issue after issue, women are more liberal than men, save for one: Men are more likely than women to support the legalization of marijuana. Americans are becoming more supportive of marijuana legalization each year but the gender gap remains a constant: While 68 percent of men now support marijuana legalization, only 56 percent of women do.
