A few months ago, I had a young patient who was struck by a car and was left with a broken tibia (that’s your shinbone). We fixed him on the same day, and, thanks to relatively non-invasive laparoscopic surgery, he could walk immediately after his operation. In fact, given that he was young, healthy and […]
When a virus invades your cells, it changes your body. But in the process, the pathogen changes its shape, too. A new mathematical model predicts the points on the virus that allow this shape-shifting to occur, revealing a new way to find potential drug and vaccine targets. The unique math-based approach has already identified potential targets […]
Snorting powdered smallpox scabs and jumping into the beds of those freshly dead from yellow fever. Humanity has gone to extreme lengths in search of immunity before. — Read more on ScientificAmerican.com Source link

He’s a physics professor at the Center for Astrophysics & Space Sciences of the University of California, San Diego. And he’s the author of the book Losing the Nobel Prize: A Story of […]
As coronavirus has swept through the United States, finding the true number of people who have been infected has been stymied due to lack of testing. Now, official counts of coronavirus deaths are being challenged, too. In Colorado, for example, a Republican state legislator has accused the state’s public health department of falsely inflating COVID-19 deaths; in Florida, […]
As figures emerge about the disproportionate toll that COVID-19 is taking on people of colour in the United States, scientists are suggesting measures to help mitigate the inequalities. They say that better data are needed on the incidence of the disease, that testing needs to be ramped up and that hospitals serving people at-risk need […]
Since I last sat down to write From the Editor a few short weeks ago, the toll of the coronavirus pandemic has been staggering: at press time, more than 180,000 deaths globally and countless lives upended. Most of the planet is still on lockdown. At times it seems unreal, although it shouldn’t. Many public health […]
Native to the Indian and Pacific oceans, lionfish invaded coral reefs in the Bahamas beginning in the early 2000s—likely when multiple aquarium owners surreptitiously liberated some of these fast-growing tank menaces into the Atlantic. As new predators with no enemies and venomous spines, lionfish have multiplied almost unimpeded and have wreaked havoc on Bahamian coral […]
We know by now that COVID-19 disproportionately affect adults 65 years and older, who are more likely to have severe outcomes. Older adults account for up to nearly two thirds of hospital admissions in the United States due to the coronavirus. On top of this, measures implemented to slow the spread of the virus, such […]
Originally published in August 1906 Credit: Scientific American Advertisement “Some years ago Eugène Dubois discovered in the island of Java some bones from a prehistoric animal, which might have formed the so-called missing link in the chain of descent of man from monkey. Julius Kollman is rather of the opinion that the direct antecedents of […]
