Why Carefree Lady Fish Grow Larger Genitals

by Elizabeth Preston in Inkfish



The history of Bahamas mosquitofish is written in their genitals. Though you'd have a hard time locating a female fish's reproductive parts, they tell a story of predators, suitors, and finding a way to regain control.

Gambusia hubbsi arrived at Andros Island, in the Bahamas, about 15,000 years ago. The little fish live in vertical, water-filled caves called blue holes. Populations separated from each other by these caves are in the process of evolving into different species, pushed by ........ Read more »

Argania spinosa has goat ornaments and makes a useful oil

by Rosin Cerate in Rosin Cerate

Argania spinosa (argan) is a tough little tree endemic to a limited area in southwestern Morocco and a bit of very western Algeria (Tindouf). Patchy forests of the tree cover about 800,000 hectares of the semi-arid Sous valley. These represent a unique biotope and have been designated a fancy UNESCO biosphere reserve. The presence of the forests slows desertification, as the drought-resistant trees act to stabilize the soil. Argan trees can live up to 250 years and are able to make do ........ Read more »

To Avoid Mosquitoes, Stop Breathing and Be Invisible

by Elizabeth Preston in Inkfish



Hungry mosquitoes use an arsenal of sensory tools to hunt you down. They sniff out the carbon dioxide you exhale; they home in on your heat signature. But a previously under-appreciated tool in the mosquito's kit is the same one you use just before slapping at it in horror: vision.

At Caltech, Floris van Breugel put mosquitoes in a wind tunnel to tease apart how they find their meals. He used Aedes aegypti, a tropical species that spreads yellow fever and other diseases. The insects wer........ Read more »

Can we use economic information to anticipate a fishery collapse?

by sceintists from the Marine group at CEES in Marine Science blog




This paper investigates the scope for resilience indicators to predict an upcoming stock collapse. We find that economic information, such as profits, may complement biological information when assessing the state of fisheries.

The story of a cave and climate change

Old writings spanning the last four hundred years have been discovered in China that detail eras of drought. Using these as a starting point, researchers have connected the time periods with changes in rainfall to predict future droughts in the region.... Read more »

Nutrient oasis is just a nice way of saying rotting corpse

by Rosin Cerate in Rosin Cerate

A whale fall is a pleasant little ecosystem that springs up whenever a whale dies and sinks to the bottom of deeper parts of the ocean. Sunlight doesn't penetrate to such depths, so there aren't any plants or algae churning out bits of easily digestible organic matter for other organisms to eat. Thus, it's feast or famine for any creatures living in the deep sea, and a whale carcass is a five star buffet. Whale fall communities are mostly made up of invertebrates, including worms capable of........ Read more »

Sports Stadiums Make Bats into Winners and Losers

by Elizabeth Preston in Inkfish



Bats are indifferent to whether we're playing soccer, baseball, or beach volleyball under our stadium lights. They only care about the game of catch they're playing with all the bugs attracted to the glow. As bats stuff themselves on swarms of sports-adjacent insects, though, our stadiums may be aiding certain bat species and wiping others out.

Any bat that's willing to visit a lit-up sports stadium will find a bug bonanza there, says Corrie Schoeman, an ecologist at the University of........ Read more »

Some vaccines support evolution of more-virulent viruses

by Dr. Jekyll in Lunatic Laboratories

Scientific experiments with the herpes virus such as the one that causes Marek’s disease in poultry have confirmed, for the first time, the highly controversial theory that some vaccines could allow more-virulent versions of a virus to survive, putting unvaccinated individuals at greater risk of severe illness. The research has important implications for food-chain security and food-chain economics, as well as for other diseases that affect humans and agricultural animals.... Read more »

Plants Murder Bugs to Pay Their Bodyguards

by Elizabeth Preston in Inkfish



It's not only carnivorous plants that bugs have to watch out for. Sure, if an ant tumbles into a pitcher plant or a spider stands in the open maw of a Venus flytrap, we know what's coming next. But certain innocent-looking plants—perhaps very many of them, even including ones in your own yard—murder hosts of insects that they have no plans to eat. They lure passing bugs into a slow death, then exchange their corpses with other insects for protection.

One of these plants is the serp........ Read more »

Study finds metal foams capable of shielding X-rays, gamma rays, neutron radiation

by Dr. Jekyll in Lunatic Laboratories

Research from North Carolina State University shows that lightweight composite metal foams are effective at blocking X-rays, gamma rays and neutron radiation, and are capable of absorbing the energy of high impact collisions. The finding means the metal foams hold promise for use in nuclear safety, space exploration and medical technology applications.... Read more »

Vaginal douches may expose women to harmful phthalate chemicals

by Dr. Jekyll in Lunatic Laboratories

Women who use feminine care products called douches may increase their exposure to harmful chemicals called phthalates–and black women may be at particularly high risk due to frequent use. Public health officials advise against the use of douching products, which can hide vaginal infections and lead to other serious health problems. Despite that, douching products are still a popular item on the drug store shelf, and are disproportionately used by black women.... Read more »

The Hidden Microbial World On Your Cash And What It Means For Your Health

by Geoffrey Hannigan in Prophage

We have all thought and talked about how dirty money is. Those notes are transferred all over the world, touched by thousands of people, and find themselves in every sort of hygienic situation. But how dirty is money really? What kinds of microbes (bacteria, viruses, etc) are sitting on your cash, and can they make you sick? To provide us with some insight ...... Read more »

Colour changing fruits and veggies

by Rosin Cerate in Rosin Cerate

The fleshy parts of plants we eat tend to change colour. This can be due to ripening (e.g. various berries turning red as they mature), intentional injury (e.g. apple slices turning brown after being cut), or changing external pH (e.g. red cabbage turning pink in vinegar). Let's look a bit at how and why this happens using a couple of examples.Strawberry fruit develops through green, white, and red stages. These correspond to changing levels of chlorophyll, anthocyanins, flavonoids, tannins, and........ Read more »

I Caught a Fish With a Snake Inside, is it Safe to Eat? Turning Citizen Science into Publications.

by David Steen in Living Alongside Wildlife

While filleting a bass I found a dead snake inside, when the fish was caught it was a healthy fighting fish. My question is: Is it safe to eat the fish? Thanks,

Ron



    You better believe that this e-mail caught my attention. It reminded me of this letter about whether it was safe to eat a fish that had been bitten by a Cottonmouth. In that case, I probably would not eat the fish. But, I did... Read more »

Weirdo Deep-Sea Anemone Kills a Giant Worm, Goes for a Walk

by Elizabeth Preston in Inkfish



If you already think everything at the bottom of the ocean is slightly terrifying, Iosactis vagabunda won't change your mind. It's transparent, can tunnel underground, and hunts animals 15 times its size. And scientists are now realizing that there might be way, way more of these roaming killers than they'd previously thought.

Iosactis vagabunda lives on the Porcupine Abyssal Plain, a seabed southwest of Ireland that ranges from 4,000 to nearly 5,000 meters deep. The species was alread........ Read more »
