As Ocean Water Gets Worse, Sharks' Teeth Start to Dissolve

As Ocean Water Gets Worse, Sharks' Teeth Start to Dissolve

Sharks have been on this planet for more than 400 million years. They're older than trees, the North Star, and even the rings of Saturn. They've seen and been through it all. But the horrifying effects of human driven climate change could be what finally proves too much for these ancient beings. As we continue to pump astronomical amounts of carbon dioxide into the atmosphere, nearly a third of it gets absorbed by the ocean, gradually making its water more acidic. For sharks, the consequences could be horrifying. New research suggests that this acidifying could dissolve and weaken shark teeth, […]

Since its initial synthesis by the German pharmaceutical company Merck in 1912, the drug 3,4-methylenedioxy-methylamphetamine, which is better known as "ecstasy," MDMA, or "Molly," has lived many lives. From its brief time being tested as a top-secret truth drug in US Army trials during the 1950s to its dual uses as a therapeutic tool and party drug throughout the 1960s and 70s, the compound's propensity for making those who take it feel the love has made it one of the most popular substances in modern history. Being banned in governments around the world starting in the mid-1980s didn't put much […]

Aug. 30, 1984: Space Shuttle Discovery launches

The third member of NASA’s space shuttle program, Discovery had a fraught journey to its launch. First, a test in June of 1984 found a flaw in the thermal shield; then a launch scheduled for later the same month was delayed due to a computer failure. Attempt No. 2 was halted only four seconds before Continue reading "Aug. 30, 1984: Space Shuttle Discovery launches" The post Aug. 30, 1984: Space Shuttle Discovery launches appeared first on Astronomy Magazine .

Scientists Say They May Have Just Figured Out the Origin of Life

Scientists Say They May Have Just Figured Out the Origin of Life

How did the building blocks of life come together to spawn the first organisms? Scientists just got a major clue. In a new study published in the journal Nature, a team of biologists say they've demonstrated how RNA molecules and amino acids could combine, by purely random interactions, to form proteins — the tireless molecules that are essential for carrying out nearly all of a cell's functions.  Proteins don't replicate themselves but are created inside a complex molecular machine called a ribosome, based on instructions carried by RNA. Now we've gotten a glimpse at how proteins could form before these […]
