It comes back bearing a large haul of tilapia and carp -- and that is exactly the problem. Altamirano is one of just 20 or so fishermen who remain in the floating gardens of Xochimilco, an idyllic network of lakes, canals and artificial islands improbably tucked into the urban sprawl of Mexico City.

How controversial science can make it harder to get an abortion

Thu, 17 Aug 2017 17:07:42 -0400

An abortion can be an emotional experience that raises questions about a woman's relationships, past regrets, and future. She might want to confide in someone about these feelings in the following weeks, months, or years.  Abortion opponents have taken that complex reality to a disturbing extreme, with the hope of convincing the public and lawmakers that ending a pregnancy puts many women at significant risk for mental health problems like substance abuse, depression, and suicide.  SEE ALSO: Why 'Handmaid's Tale' costumes are the most powerful meme of the resistance yet To vividly and persuasively make their case, anti-abortion rights activists often point to scientific research that makes dubious connections between the medical procedure and long-term psychological turmoil or suffering. What politicians looking to restrict abortion don't tell the public is that not all research in this field is equal.  This strategy has found its way into statehouses across the country. A recent report from the Guttmacher Institute, a research and advocacy organization, found that more than half of all women of reproductive age in the U.S. live in a state with at least two types of abortion restrictions that have no basis in scientific evidence, including counseling requirements and mandatory waiting periods.     Not all of these laws are explicitly premised on the notion that abortion causes lasting emotional or psychological damage, but many are routinely defended as measures to protect women's health.  "I don't think requirements are the solution to anything," said Melissa Madera, who has interviewed 288 people about their abortion experiences as founder and director of the podcast The Abortion Diary. "No one needs to tell us that we need to take time to think. People are doing it anyway." I've had an abortion & talked w/ over 200 people who've had abortions. This is what I have to say to Congress. — melissa.madera (@drmelissamadera) January 31, 2017 Meanwhile, a battle over the science of abortion and mental health continues to unfold: Reputable medical and professional organizations in the field have found that the procedure doesn't cause long-term psychological harm, but a group of researchers insist it's devastating. The losers in this fight? People who've had or may need an abortion and hear conflicting messages about the research, and who may face long waits to get care because of laws designed to slow the process.  While many women who've had abortions can share how the experience affected them, scientists can't rely on these anecdotes to draw conclusions about mental health for an entire population. Instead, the best scientific research minimizes bias and controls for variables. When randomized trials are possible, scientists can recruit volunteers who are then assigned different outcomes.  With abortion, however, that would mean randomly selecting whether a woman carries an unintended pregnancy to term or ends it — disturbing, unethical, and impossible. Instead, research on abortion and mental health outcomes must rely on what are known as observational studies. That means women choose whether to end or complete their pregnancy, and then scientists follow those two groups over time to observe and compare their mental health outcomes. Scientists can make inferences about what they find in observational studies, but it's more challenging to draw a straight line between cause and effect. Efforts to untangle the relationship between pregnancy and a specific mental health experience, particularly when abortion is involved, often fall short, said Julia Littell, a professor of [...]

Stunning new view of Jupiter flips Great Red Spot on its side

Thu, 17 Aug 2017 17:55:15 -0400

(image) A new view of Jupiter takes the usual shot of the planet's Great Red Spot and flips it on its side. The captivating new perspective comes from an image created by two citizen scientists who used data from the JunoCam on NASA's Juno spacecraft that's been in orbit for more than a year studying the planet, according to NASA. The north end of the planet is shown on the left side of the new photo (above) and that's where the Great Red Spot rages. SEE ALSO: Perhaps staring at this photo of a storm on Jupiter will help us all relax after a hard week The image comes from the recent batch of photos and data from the Juno spacecraft's fly-by on July 10. The Great Red Spot, a 10,000 mile-wide storm, had quite a photo session when the spacecraft flew 5,600 miles above it. For this newer image, created by Gerald Eichstädt and Seán Doran, the spacecraft was 10,274 miles above the planet and its clouds. The Great Red Spot is usually photographed on top, like this photo below, so the storm gets a different vantage point in this latest image.

New Magic Mushrooms Discovery Could Reveal How to Make Your Own Drugs

Around 200 types of mushrooms produce psilocybin, and they’ve been used ceremonially for millennia. Albert Hofmann, the Swiss chemist who synthesized LSD, identified psilocybin as the active ingredient in magic mushrooms and determined its structure in 1959.
