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
Pluto, the Solar System’s largest dwarf planet, just became even more interesting with a report that icy lava flows have recently covered substantial tracts of its surface. In this context, “recently” means probably no more than a billion years ago. That’s old, of course – and there is no suggestion that volcanoes are still active – but it’s only a quarter the age of the Solar System and no one knows how Pluto brewed up the heat needed to power these eruptions.The news, coming nearly seven years after NASA’s New Horizons probe made its spectacular flyby of Pluto on July 14, 2015, is thanks to analysis of images and other data by a team led by Kelsi Singer of the Southwest Research Institute in Boulder, Colorado.
Thankfully, most people who get COVID–19 don’t become seriously ill – especially those who are vaccinated. But a small fraction do get hospitalized, and a smaller fraction do die. If you are vaccinated and catch the coronavirus, what are your chances of getting hospitalized or dying?As an epidemiologist, I have been asked to respond to this question in one form or another throughout the pandemic. This is a very reasonable question to ask, but a challenging one to answer.
For more than a century, journalism education prepared young people for the role of full-time professionals employed by sizeable news organisations. But the advertising-based business model that sustained journalism is collapsing because of new technology, and jobs of the old kind are becoming scarce. The educational model, too, must change to accommodate the new realities.
Eighteenth-century socialites have been depicted as vain, silly women who were poisoned by their white lead makeup. The Countess of Coventry, Maria Gunning — a society hostess renowned for her beauty — is said to have refused to stop wearing foundation containing white lead, even as she lay dying. Why would women of that era knowingly choose to wear makeup that was killing them? Was beauty worth dying for? Or was the makeup not to blame?
Was Charles Darwin a one-hit wonder? According to scientists who take a gene’s-eye view of evolution, the 19th-century English naturalist contributed one crucial idea to understanding how species change: natural selection, or “design without a designer”. However, a book of Darwin’s that is little read by modern evolutionists – The Expression of the Emotions in Man and Animals – turns out to contain valuable lessons for scientists seeking to understand how and why humans do what we do.
The rise of the omicron variant has caused havoc around the world, just as the emergence of the delta and alpha variants did before. A pattern has emerged, with the world scrambling to respond to a new form of the coronavirus every six or so months. How can we reduce the risk of new variants appearing again and again?Firstly, let’s consider how they emerge. A virus reproduces by making copies of itself. Every time it replicates, there’s a tiny chance that an error occurs in the copying of the virus’s genetic sequence.
Check out your birth certificate and surely you’ll see a designation for sex. When you were born, a doctor or clinician assigned you the “male” or “female” label based on a look at your genitalia. In the U.S., this has been standard practice for more than a century. But sex designation is not as simple as a glance and then a check of one box or another. Instead, the overwhelming evidence shows that sex is not binary. To put it another way, the terms “male” and “female” don’t fully capture the complex biological, anatomical and chromosomal variations that occur in the human body.
Brad Pitt’s Make It Right Foundation built 109 eye-catching and affordable homes in New Orleans for a community where many people were displaced by damage wrought by Hurricane Katrina in 2005. Now this housing development is in disarray.
The Centers for Disease Control and Prevention has changed its guidelines about masks and respirators a number of times over the past two years and gave its most recent update on Jan. 14, 2022. The update states that cloth face coverings offer the least protection from the coronavirus compared with surgical masks or N95-style masks. Christian L'Orange is a mechanical engineer who has been testing the performance of masks for the state of Colorado since the beginning of the pandemic. He explains the new CDC guidelines and the science of what makes for a good mask.
Around the world, populations of many beloved species are declining at increasing rates. According to one grim projection, as many as 40% of the world’s species may be extinct by 2050. Alarmingly, many of these declines are caused by threats for which few solutions exist.Numerous species now depend on conservation breeding programs for their survival. But these programs typically do not encourage species to adapt and survive in the wild alongside intractable threats such as climate change and disease.
Several international airlines recently canceled flights into certain US airports over concerns the rollout of 5G mobile communication technology could interfere with some planes’ equipment. After warnings about the potential problem from aviation bosses and the Federal Aviation Administration, telecommunications companies AT&T and Verizon delayed activating some 5G masts around US airports.
In a horrendous accident, a cinematographer has died and a director has been injured after Alec Baldwin fired a prop gun while filming in New Mexico.When shooting a film with guns, there are many choices to make: each prop needs to be appropriate for the character, and appropriate for the scene. There is also the choice of whether you will use replica weapons, real weapons, or a mix.But most importantly, everyone on set needs to know how to work alongside guns.
