Female Scientists Told to Get a Man to Help Them With Their Paper

This just in from the land of great sexism: two female scientists had a manuscript rejected by a peer-reviewed journal because they didn’t ask a man for help. An unnamed peer reviewer for the journal PLoS One suggested that Drs. Fiona Ingleby and Megan Head find male co-authors—any men at all—for a paper they’d… » 4/30/15 12:20pm 4/30/15 12:20pm

Check out every single kind of microbe in your body online — all 5 million of them

The initial phase of the Human Microbiome Project has come to an end — and with it, the mapping of the full community of microbes that inhabit all the various nooks and crannies of the healthy human body. The results of the exhaustive study will be published as a collection in PLoS, making their findings available to… » 6/14/12 11:40am 6/14/12 11:40am

The three main problems with sexual reproduction, as explained by science

Over at PLoS Biology, biologist Denis Roze has a fascinating article introducing a question that may at first seem obvious, but is in fact one of the enduring mysteries of biology: Why bother to have sex? People interested in evolutionary biology may already be familiar with the reasons why sexual intercourse is an… » 5/23/12 11:45am 5/23/12 11:45am

Why does it cost $20,000 a year to subscribe to a science journal?

What happened when Oliver Sacks started to hallucinate

Over at NeuroTribes, a new blog in the just-born science blog network at PLoS (it's one for your feed reader), Steve Silberman has an exclusive interview with celebrated neuroscientist Oliver Sacks. For the first time, Sacks is speaking out about the illness that nearly cost him his eyesight - a topic that he treats… » 9/01/10 2:00pm 9/01/10 2:00pm

Fungus Could Be Among Fastest Lifeforms on Earth

Slow-growing fungus may be one of the fastest lifeforms on Earth — at least when it comes time to spread its seeds. A group of scientists recently used ultra-high-speed cameras to record spores being shot out of fungi (pictured). Some of them were launched out of the fungi at 55 mph, zooming several feet before… » 9/22/08 7:00am 9/22/08 7:00am

Europeans Pick Mates By Smell More Often than Africans Do

Scientists have known for a while that humans seem to pick mates partly based on the way they smell. That's because a person's smell is related to their Major Histocompatibility Complex (MHC), a cluster of genes that shape a person's immune system. For years, scientists have debated whether people pick mates based on… » 9/12/08 3:20pm 9/12/08 3:20pm

Possible Cure for Ebola Could Revolutionize Antivirals

Ebola is the poster virus for outbreak scares because it spreads extremely fast and kills 90 percent of its victims by causing them to bleed uncontrollably. Featured in science-scare book The Hot Zone » 9/03/08 5:51pm 9/03/08 5:51pm and countless cheesy movies, Ebola is considered ripe for development into a bio-weapon. But now it seems that a…

Usually, books are presented as an antidote to a TV-controlled populace. But now a new neuroscience study reveals that books control people's minds and emotions in exactly the…

Scientists Identify Genes that Could Turn Ordinary People into Supergeniuses (or Mindless Drones)

Click to view It's clear that there's a specific set of genes responsible for brain development when you're in the womb, and that those genes affect your ability to learn later on. But now a group of researchers in the U.S. and Canada have identified those genes. And their discovery could represent the first step in… » 7/06/08 4:00pm 7/06/08 4:00pm

Life Expectancy Going Down in the United States

In some parts of the United States, medicine has not improved the average life expectancy — and in fact, the average lifespan has been going steadily downward since the 1980s. No, immigration is not to blame for these shifting numbers. These are U.S. citizens in hundreds of different counties whose lives are getting… » 4/23/08 3:56pm 4/23/08 3:56pm

Geneticists Discover a Way to Extend Lifespans to 800 Years

There is now a way to extend the lifespan of organisms so that humans could conceivably live to be 800 years old. In an amazing development, scientists at the University of Southern California have announced that they've extended the lifespan of yeast bacteria tenfold — and the recipe they used to do it might easily… » 1/16/08 1:30pm 1/16/08 1:30pm
