Godzilla of the Galápagos and other speciation stories

Yet despite their brutish appearance, marine iguanas are extremely placid herbivores, posing a threat only to the algae upon which they feed. We now know that these creatures represent one of the oldest living lineages of the archipelago and as such, their evolution is deeply intertwined with the history of the islands themselves, a discovery foreshadowed by Darwin‘s observation that “They assuredly well become the land they inhabit”.

American healthcare: are you an expert? [Quiz]

As technology and education become more broadly accessible, people are being exposed to more information than ever before. It’s easier than ever to choose convenience over reliability or accuracy—to search for symptoms on WebMD instead of asking a doctor, or consult Wikipedia for definitive answers to every question. All this newly accessible yet unreliable information has produced a wave of ill-informed and angry citizens.

The best baby money can buy: are you sure about that?

Take a look at the back page advertisements in any college newspaper. Dotted among the classified ads, there will invariably be an invitation or two to male undergraduates to sell their sperm. It’s an easy and hardly arduous way to make money, and pretty speedy too. Masturbate, ejaculate, hand over the results and you’re on your way with a little money in your pocket.

Exploring travel medicine with the CDC

It was a historical moment for the International Society of Travel Medicine who celebrated its 25th anniversary this year at the 15th Conference of the International Society of Travel Medicine (CISTM15) in sunny Barcelona. We asked Phyllis Kozarsky, Professor of medicine and chief medical editor for the CDC Yellow Book 2018, a few questions around the connections between travelers and antimicrobial resistance,

The impact of intergenerational conflict at work

Recently, several colleagues and I noted that conflict in the workplace can emerge as a result of perceptions of differences related to what members of various generations care about, how they engage in work, and how they define self and others. We also noted several ways in which these conflicts might be resolved including achieving results, managing image in the workplace, and focusing on self in challenging interactions.

Opening the door for the next Ramanujan

It is still possible to learn mathematics to a high standard at a British university but there is no doubt that the fun and satisfaction the subject affords to those who naturally enjoy it has taken a hit. Students are constantly reminded about the lifelong debts they are incurring and how they need to be thoroughly aware of the demands of their future employers. The fretting over this within universities is relentless.

Reflections on Freud, the first “wild analyst”

Sigmund Freud was a more radical and speculative thinker than many have been willing to concede. This is apparent in his many discussions of childhood sexuality. For example, few really understand how Freud’s conclusions about childhood sexuality predate by decades the clinical observations of actual children – later done by dutiful analysis, most often by women analysts like Melanie Klein and Freud’s own daughter Anna Freud

Are Americans in danger of losing their Internet?

It’s hard to imagine life without the Internet: no smart phones, tablets, PCs, Netflix, the kids without their games. Impossible, you say? Not really, because we have the Internet thanks to a series of conditions in the United States that made it possible to create it in the first place and that continue to influence its availability. There is no law that says it must stay, nor any economic reason why it should, if someone cannot make a profit from it.

The less mentioned opioid crisis

You’ve probably seen the dramatic photo of the Ohio couple slouched, overdosed, and passed out in the front seats of a car, with a little kid sitting in the back seat. Even if you haven’t seen that picture, images and words of America’s opioid overdose epidemic have captured headlines and TV news feeds for the last several years. But there’s a different image seared into my mind, a mental picture of a different little kid and two adults.

Slaves to the rhythm

I met up with Russell Foster in 1996 when I was writing a book on the social impact of the 24 hour society. I wanted to know what effect working nights had on human biology and health. At the time Russell was Reader at Imperial College. Since then he has become professor of circadian neuroscience at Oxford University; a Fellow of the Royal Society; and he has a shelf full of medals from scientific societies around the world.

Johnny had Parkinson’s…and music helped him walk

One day we stumbled upon something that would end up helping Johnny on this twice daily haul. Given our shared history as musicians, it’ll come as no surprise that Johnny and I often talked about music. As Johnny was prepping to take the first step, we joked about singing a march so he could march his way down the hall. It was Johnny’s idea to use Sousa’s Stars and Stripes, a march he liked.

Addressing rare, toxic downside of immunotherapy

The American Society of Clinical Oncology and the National Comprehensive Cancer Network announced in mid-February their intent to issue day-to-day guidelines for physicians managing severe side effects from immune checkpoint inhibitors—a type of immunotherapy that works with a patient’s own immune system to attack cancer. They hope to release a document by the end of the year.

Can green entrepreneurs save our planet?

Less than a year after the governments of the world came together to sign the Paris Agreement on climate change, the United States has inaugurated a new president, Donald Trump, who denounces the whole idea as a Chinese hoax. How did we get here?

Slipping expectations for child outcomes

Certainly we should be happy that kids from “at risk” environments graduate from high school and do not end up in prison for life. But is this enough to aim for? We may not score their life outcome as minus 5 (on a -10 to +10 scale), but Chiron’s life outcome does not warrant much more than a zero. Why? Because his intelligence, unique gifts, and potential were not fostered (which would go on the plus side of zero).

Celebrating 100 years of Urie Bronfenbrenner

n the United States, currently, about 15 million children (almost a quarter of the global child population) live in families whose income falls below the federally established poverty level. The damaging effects on children’s and families’ development were something that was a life-long concern of Urie Bronfenbrenner.

100 years of E. coli strain Nissle 1917

Escherichia coli (E. coli) is a common bacteria found in the the lower intestine of warm-blooded animals, including humans. Whilst most strains are harmless, some can cause serious gastroenteritis, or food poisoning. However, one special strain, E. coli strain Nissle 1917 (EcN), is specifically used to prevent digestive disruption. Since its discovery 100 years ago, EcN is probably the most intensely investigated bacterial strain today.
