A Venusian Mystery Explored Once More

by Gabriel in Lunatic Laboratories

Venus, the place where women are from... supposedly. To say Venus has a harsh climate would be an understatement, this is one of many reasons why we will never (or maybe not soon) see a "long lasting" Venus rover counterpart to our Mars rover missions. Still, the planet (much like all the other plants) can teach us a lot about not just our own origins, but the origins of the universe. Also like all our neighbor planets Venus is hiding something beneath its brilliant shroud of clouds, a mystery t........ Read more »

A look at Air Pollution and Your Body

by Gabriel in Lunatic Laboratories

We have all probably seen stories from China on the horrid air pollution there. Accompanying those reports of course are the statistics for air pollution that deaths have caused. For the record, the World Health Organization estimated that ambient air pollution caused 3.7 million premature deaths (worldwide) in 2012 alone – yet what exactly happens to your body when it encounters pollutants?...

Carbon’s Place in a Silicon World

by Gabriel in Lunatic Laboratories

Everything is silicon based, well mainly your computer, your TV, your ipad, and pretty much every piece of electronics in existence. Still the world turns and so does technology; at a similarly fast pace no less. Even as the 2014 Nobel Prize in Physics has enshrined light emitting diodes (LEDs) as the single most significant and disruptive energy-efficient lighting solution of today, scientists around the world continue unabated to search for the even-better-bulbs of tomorrow. In this search we ........ Read more »

These Tiny Animals Live Only on Driftwood

by Elizabeth Preston in Inkfish

Maybe you gave your last realtor a long series of must-haves: a washing machine in unit, proximity to the train, a gas stovetop. But there’s no way you’re as picky as the driftwood hopper. This minute crustacean will only live in rotting chunks of driftwood. David Wildish, a marine zoologist at Fisheries and Oceans Canada, […]The post These Tiny Animals Live Only on Driftwood appeared first on Inkfish.... Read more »

Your Artificial Sweeteners, Your Bacteria, and Your Health

by Geoffrey Hannigan in Prophage

The red of bearded vultures—allure or cure?

by Yao-Hua Law in TORCH

[This story first appeared on Earth Touch News] Soaring high among the mountains from Europe to China and to Africa, the bearded vulture (Gypaetus barbatus) commands attention at any lunch party. It likes to gate crash into the frenzy around carrion, pushing other scavengers aside with wings that could stretch the height of Michael Jordan, […]... Read more »

Ecology of cancer: mimicry, eco-engineers, morphostats, and nutrition

by Artem Kaznatcheev in Evolutionary Games Group

One of my favorite parts of mathematical modeling is the opportunities it provides to carefully explore metaphors and analogies between disciplines. The connection most carefully explored at the MBI Workshop on the Ecology and Evolution of Cancer was, as you can guess from the name, between ecology and oncology. Looking at cancer from the perspective […]... Read more »

Solar Panel Hybrid is Cheap and Super Efficient

by Gabriel in Lunatic Laboratories

Solar cells are inefficient, it’s a sad fact. With todays technology they boast about a 10-15% efficiency, compare that to todays gas engine at roughly 20-25% and you can see it’s not quite up to par. Well that could all change very soon thanks to a new method for transferring energy from organic to inorganic semiconductors. This could boost the efficiency of widely used inorganic solar cells to as close as 100% efficiency as they can get.... Read more »

Climate change roundup: underestimated ocean heat content and emissions from the peatlands!

Scientists Recommend Vole Shaving

by Elizabeth Preston in Inkfish

Sometimes scientists need to make their research subjects’ lives harder. No matter how much affection they may feel for those flatworms or fish or pigeons, there are certain things they can only learn by forcing the animals to use more energy. But for animals living in the wild, this can be tricky. Now scientists studying […]The post Scientists Recommend Vole Shaving appeared first on Inkfish.... Read more »

Orange Corn Aims to Fight Vitamin A Deficiency

by Gabriel in Lunatic Laboratories

GMO food is still a hot button topic, honestly for no other reason than fear. Sure Monsanto is a big evil corporation, but the science is only as bad as what you do with it. In the modern fortified world we don’t think about vitamin deficiency or the horrible things that come with it, however vitamin A deficiency is a huge problem in developing countries. To combat this researchers have identified a set of genes that can be used to naturally boost the provitamin A content of corn kernels, a fi........ Read more »

The Biology of Nagging

by Miss Behavior in The Scorpion and the Frog

A female pied flycatcher can't feed herself sufficientlywhile she incubates her eggs and newly-hatchedchicks. Photo by Alejandro Cantarero.I have been blessed with the fortune of not just having two healthy and happy babies, but being able to spend much of the spring and summer nurturing them and watching them develop and grow. But it has not been all roses: their smiles beam through the fog of my sleep deprivation and exhaustion. Their tears are met with my own. Our clothes are stained in a ra........ Read more »

Using “Programmable” Antibiotics to Attack Drug-Resistant Microbes

by Gabriel in Lunatic Laboratories

The body is pretty great at self regulation, that is up until it isn't. The antibiotic era was one that improved human health hundreds of times over. Unfortunately health is a joint effort, a multitude of microbes scientists have found populating the human body have good, bad and mostly mysterious implications for our health. But when something goes wrong, we defend ourselves with the undiscriminating brute force of traditional antibiotics, which wipe out everything at once like a wild fire, reg........ Read more »

The Path of Antibiotic Resistance

by Gabriel in Lunatic Laboratories

MRSA, not that long ago we had no idea what MRSA was… mostly because it hadn’t come into prevalence. With an increase in the use and abuse of antibiotics there has been an ever growing pressure for the pathogens we treat to mutate in order to survive, this pressure is called selective pressure and helped cause drug-resistance in pathogens. In response to the rise of these drug-resistant pathogens, doctors are routinely cautioned against over prescribing antimicrobials. But when a patient has........ Read more »

Tricksy insects sing a song of love and deceit

by neuroecology in Neuroecology

Beyond a spider snacking on an unfortunate fly, the social lives of insects tend to go unrecognized. Perhaps you notice all the ants marching in a line, or bees heading back to a nest, but it all seems so mechanical, so primal. … Continue reading →... Read more »

How to Say “SOS” in Catfish

by Elizabeth Preston in Inkfish

It’s good to have a plan in case of emergency. If there’s a fire, take the stairs to the ground floor. If a bird tries to eat you, say “ERK ERK ERK” by grinding your spine bone against your shoulder bone until it drops you. That latter one will work best if you’re a certain […]The post How to Say “SOS” in Catfish appeared first on Inkfish.... Read more »

One Thing Is Just Like The Other – Sort Of

by Mark Lasbury in As Many Exceptions As Rules

Recent studies have illustrated how complicated evolution by descent with adaptation can be. Convergent evolution and parallel evolution explain the fingerprints of koalas and the marsupial and placental saber-toothed cats. Dollo’s Law of Irreversibility has been shown to be plastic, as frogs have re-evolved mandibular teeth and stick insects have lost and regained wings several times. ... Read more »

A Warm Winter Legacy: Leaf Flushing and Senescence Long-Term

by Melissa Chernick in Science Storiented

Fall is in the air. Here in North Carolina that means drastic temperature swings that cause me to dress incorrectly on any given day. It also means the arrival of fall colors. Indeed, fall colors are incredibly beautiful, but biologically speaking, you are watching death happen. This autumn splendor got me to thinking about these colors a little closer, specifically the phenology of trees.Phenology is the study of the annual timing of recurring life cycle events. The timing of these events is t........ Read more »
