Killer sponges sound like creatures from a B-grade horror movie. In fact, they thrive in the lightless depths of the deep sea. Scientists first discovered that some sponges are carnivorous about 20 years ago. Since then only seven carnivorous species have been found in all of the northeastern Pacific. A new paper authored by MBARI marine biologist Lonny Lundsten and two Canadian researchers describes four new species of carnivorous sponges living on the deep seafloor, from the Pacific Northwest to Baja California.
A far cry from your basic kitchen sponge, these animals look more like bare twigs or small shrubs covered with tiny hairs. But the hairs consist of tightly packed bundles of microscopic hooks that trap small animals such as shrimp-like amphipods. Once an animal becomes trapped, it takes only a few hours for sponge cells to begin engulfing and digesting it. After several days, all that is left is an empty shell.
MBARI researchers videotaped the new sponges on the seafloor, then collected a few samples for taxonomic work and species-reference collections. Back in the lab, when they looked closely at the collected sponges, the scientists discovered, as Lundsten put it, “numerous crustacean prey in various states of decomposition.”
Sponges are generally filter feeders, living off of bacteria and single-celled organisms sieved from the surrounding water. They contain specialized cells called choancytes, whose whip-like tails move continuously to create a flow of water which brings food to the sponge. However, most carnivorous sponges have no choancytes. As Lundsten explained, “To keep beating the whip-like tails of the choancytes takes a lot of energy. And food is hard to come by in the deep sea. So these sponges trap larger, more nutrient-dense organisms, like crustaceans, using beautiful and intricate microscopic hooks.”
Researchers have, for the first time, successfully grown cells ex vivo that replicates vaginal tissue and its resident microbes. One of the benefits of this feat is that it will allow scientists to investigate how prescription or over-the-counter pharmaceuticals like contraceptives, antibiotics and antifungals interact with both “good” and “bad” microbes and vaginal skin cells.
A study recently published in PLoS ONE used this model of microbial/human vaginal tissue to discover that certain bacterial communities alter the way HIV infects and replicates. Additionally, they have discovered that a bacterial community associated with bacterial vaginosis substantially reduced the antiviral activity of one of the leading anti-HIV medicines.

NASA’s newest moon probe met its end during a vaporizing crash into the lunar surface last night.
The space agency’s Lunar Atmosphere and Dust Environment Explorer spacecraft (LADEE for short) made its planned crash into the lunar surface between 12:30 a.m. EDT (0430 GMT) and 1:22 a.m. EDT (0522 GMT) on April 18, after orbiting the moon since October 2013. Scientists expected the impact, predicting that LADEE would hit the far side of the moon on or before April 21 because the probe was running out of fuel — as intended.
The impact itself was probably a violent event. NASA engineers think that the loveseat-sized probe broke apart as most of it heated up to several hundred degrees. It’s even possible that some of the material from the spacecraft vaporized during the crash, NASA officials said in a statement.

A 44-year-old French man one day went to the trip to the doctor’s because he felt a pain in his left leg. He’s a married man with two kids and a steady job.
Doctor’s found that he had hydrocephalus as a child (when your brain is filled with fluids) so they decided to run some brain scans.
What they found was that the majority of his head was filled with fluid. Over time, the buildup caused his lateral ventricles to swell so much that his brain had been flattened to a thin sheet.
Doctors estimated that his brain mass had been reduced by at most 70%, affecting the areas in charge of motion, language, emotion, and, well, everything.
Shockingly, he was fine. While his IQ was only 75, he wasn’t mentally challenged. He held a steady job, raised a family, and didn’t have trouble interacting with others.
Over time, his brain had adapted to all that pressure, and even though he had fewer neurons that most, Jacques was still a fully functional human being.
The doctors drained the fluid and while his brain is much smaller now, he is still a healthy individual with a normal life.

What We Love About The Universe and Science
Science You Can Love
Yes, you read that right; the artist Antoine Bridier-Nahmias paints with mould, marrying art and science in an unexpectedly delightful way. His strange media include various sets of bacteria and fungi, ranging in color, texture, and density, and a petri dish serves as his canvas. Once a piece is grown to his aesthetic satisfaction, the artist photographs it from above, capturing the nuances of the material in stunning resolution.
Bridier-Nahmias’s images, perhaps revolting if seen inside your fridge, are visually enthralling when viewed in the sterile confines of the dish. Like strange and serendipitous science experiments, the moldy surfaces create ordered geometric patterns found time and again in nature; unlike paint, the bacteria reproduces itself in accordance with complex biological laws, forming perfect circles and straight lines that emanate from their centers.
More than worth it. This is one hell of a game.
Right now, 500 light years away from Earth, there’s a planet that looks a lot like our own. It is bathed in dim orangeish light, which at high noon is only as bright as the golden hour before sunset back home.
NASA scientists are calling the planet Kepler-186f, and it’s unlike anything they’ve found. The big news: Kepler-186f is the closest relative to the Earth that researchers have discovered.
It’s the first Earth-sized planet in the habitable zone of another star—the sweet spot between too-hot Mercury-like planets and too-cold Neptunes— and it is likely to give scientists their first real opportunity to seek life elsewhere in the universe. “It’s no longer in the realm of science fiction,” said Elisa Quintana, a researcher at the SETI Institute.
But if there is indeed life on Kepler-186f, it may not look like what we have here. Given the redder wavelengths of light on the planet, vegetation there would sprout in hues of yellow and orange instead of green.

Secretary of State Kerry has called this not just intolerable, but grotesque. I fucking agree.
This is fucking terrifying.

This Sea Robin, or Gurnard, is crawling around on fin rays modified into 6 creepy legs.
I’m almost completely certain its underwater rather than in a desert or on your ceiling waiting to pounce
