Flowers might have memories
Flowers might form their memories because of the protein that causes mad cow disease, according to a new study. Plants have long been observed to have something like memory, remembering information like when is the best time to flower and passing that information on to their offspring. They have even been known to become “forgetful” – wiping out memories of past traumas if they are causing problems.

The Physics of Peacock Tail Feathers Is Even More Dazzling Than We Realized
Male peacocks shake their brilliantly-hued, long tail feathers to attract females in a courtship display known as “train-rattling.” But scientists had never closely examined the biomechanics behind this behavior—until now. A new paper in PLOS One concludes that the frequency at which those feathers vibrate can enhance this iridescent display—even as the eyespots remain almost perfectly still.

Earth Doesn't Get Weirder Than The Bubbling Springs Of Ethiopia
It might look like a drug-induced vision of hell, but for astrobiologists, the Danakil Depression in Ethiopia is heaven. With chlorine and sulfur vapor fogs hanging above its near-boiling, bubbling salty lakes, it is one of the least hospitable places in the world.

VW and Shell try to block EU push for electric cars
VW and Shell have united to try to block Europe’s push for electric cars and more efficient cars, saying biofuels should be at heart of efforts to green the industry instead. The EU is planning two new fuel efficiency targets for 2025 and 2030 to help meet promises made at the Paris climate summit last December. But executives from the two industrial giants launched a study on Wednesday night proposing greater use of biofuels...

Can a Cat Have an Existential Crisis?
When I first adopted Lucas nine years ago from a cat rescue organization in Washington, D.C., his name was Puck. Then, almost four years ago, my husband and I had a child. Lucas, no longer the most important small creature in the apartment, retreated to the top shelf of his cat tree, where he would lie all day, staring morosely over the edge.

I Was Wrong About the Limits of Solar; PV Is Becoming Dirt Cheap.
The price of solar power is falling faster than many thought was possible. Harvard’s David Keith comes honest with us about solar power: “Facts have changed. I was wrong.” The unsubsidized electricity cost from industrial-scale solar PV in the most favorable locations is now well below $40 per megawatt-hour and could very easily be below $20 per megawatt-hour by 2020. Compared to other new sources of supply, this would be the cheapest electricity on the planet.

Scans Show 'Brain Dictionary' Groups Words By Meaning
Scientists say they have made an atlas of where words' meanings are located in the brain. The map shows that words are represented in different regions throughout the brain's outer layer. Moreover, the brains of different people map language in the same way. "These maps are remarkably consistent from person to person," says Jack Gallant, a neuroscientist at the University of California, Berkeley who led the study.

How the Other Fifth Lives
For years now, people have been talking about the insulated world of the top 1 percent of Americans, but the top 20 percent of the income distribution is also steadily separating itself — by geography and by education as well as by income. This self-segregation of a privileged fifth of the population is changing the American social order and the American political system.

Dinosaur die-off not a result of volcanoes, new study says
A new study suggests that volcanic eruptions did not lead to the extinction of the dinosaurs, and also demonstrates that Earth's oceans are capable of absorbing large amounts of carbon dioxide—provided it is released gradually over an extremely long time. Scientists have long argued over the cause of the Cretaceous-Palaeogene extinction event, during which three-quarters of all plant and animal species, including the dinosaurs...

A huge zinc surge accompanies the first spark of human life
The human egg has to be activated for an embryo to begin to develop. Now, researchers show that proper activation is accompanied by a large surge in zinc levels in the egg. This inorganic signature could be used to help IVF scientists predict which eggs will be the healthiest and most likely to be viable following implantation.

A recipe for global cooling—put seafloor on dry land near the equator
Earth’s climate has stayed within a pretty narrow range of temperatures over its history if you compare it to the inhospitable heat and cold found elsewhere in our Solar System. This relative stability has been maintained by an intricate system of interactions. On geologic timescales, the chemical commerce between the atmosphere and the rock of Earth’s crust acts as a thermostat. The weathering of common minerals includes a reaction that removes...
