Geological evidence indicates that our planet has seen five mass extinction cycles since life first appeared on the planet. While they sound like the kind of cataclysmic events that only beardy men with huge boats survive through (read that in a book once, so it must be true), they are actually an integral part of life. The cycles free up
A research group working at the Australian Grains Free Air CO₂ Enrichment facility (AgFace) in Victoria is studying the effect elevated carbon dioxide will have on crops such as wheat, lentils, canola and field pea. They grow experimental crops in the open, surrounded by thin tubes that eject carbon dioxide into the air around the plants. Findings show that crops have higher yield (up to 25% more), but less proteins. Elevated CO2 also seems to ruin bread made from the grown wheat.
Research based on recent observations of a nearby gamma-ray burst, GRB 130603B, help explain how gold, silver and other heavy metal atoms are created.
As the ISS hurtles in orbit around the Earth, an eternal freefall at 17,100 mph, its cameras, and the astronauts on board, are capturing images and footage of our planet below — much of which is from NASA, and therefore public domain.
A new project started by Green Energy Africa in September 2014 has brought solar energy to 2,000 homes in Naiputa county alone, and put new power into the hands of women who sell affordable solar installations.
The guys over at the Smithsonian Channel run a great show about plants. One of the recent short videos they posted online show how violets, touch me nots, and squirting cucumbers employ an impressive ballistic seed dispersal mechanism.
Known to feed mainly on seals, the images Jon Aars at the Norwegian Polar Institute captured of a polar bear dining on dolphins is a “culinary” first for the species. The photographs were taken in the Norwegian High Arctic, mid-April 2014. The bear was seen feeding on the carcass of one white-beaked dolphin, and covering another with snow.
The development of a method that would allow for metals to be used in 3D printing would open up a huge range of new possibilities, as the robustness and good thermal and electrical conductivity of metals lend well to a number of fields, such as microelectronics. A team from the University of Twente has developed a way to print 3D structures out of copper and gold, by using a pulsed laser to melt a thin film of metal and stacking the small droplets.
A recent study involving a Papua New Guinea tribe that practiced cannibalistic funeral customs sheds new light on prion-related conditions such as mad cow disease.
Converting the power infrastructure to rely on clean, renewable energy seems like a daunting, expensive and some would say, unachievable task. But Mark Z. Jacobson, professor of civil and environmental engineering at Stanford, and his colleagues, including U.C. Berkeley researcher Mark Delucchi, are the first to outline how each of the 50 states can achieve such a transition by 2050.
We here at ZME Science aren’t very fond of war. We much rather prefer to drink beer in the shade and solve our differences with rock-paper-scissors. But we (meaning I) also think that tanks are really awesome. They embody so much of what humanity has learned over the millennia. From fire and mining used to forge the hulls of these behemoths, to gunpowder that sends a shell kilometers away to a point that we can calculate with equations that some of the brightest minds have made possible. We spent centuries learning how to build their beating hearts.
Seven miniature species of frogs living on seven different mountain tops sounds like the premise for the next Kung Fu Panda sequel. But as researcher Marcio Pie of the Federal University of Parana and his colleagues show in a paper published in PeerJ., it is what they have found in the Atlantic Rainforest of Brazil.
The island country is preparing to launch a new energy policy, seeking to curb costs and promote the use of environmentally friendly sources of power.
Fifty years ago today, on June 3rd, 1965, 19:46, astronaut Edward White pushed away from the Gemini 4 capsule and into history as the first American to walk in space. Although a Russian had been the first to float in space, Ed White was determined to be the first to use jet propulsion to actually maneuver himself in space. With millions of
In the beginning, the Earth’s surface was a lifeless, hot, but chemically rich place. In these harsh conditions, the first amino acids synthesized from inorganic compounds, and from them, proteins formed. They built the first single cells, which went on to form plants and animals. Recent research helped us understand the process that created amino acids, and there is a widespread consensus in the scientific community as to the path cells took to evolve to complex life as we know it today.
Created by John B. Sparks and first printed by Rand McNally, the Histomap started selling in 1931 for the price of US$1. Folded in a green cover that advertised it as “clear, vivid, and shorn of elaboration,” and promising to “hold you enthralled”, the 5-foot-long work of historic awesomeness aims to deliver big.
A team of researchers from the KTH Royal Institute of Technology and Stanford University has developed a method for making elastic, shock-resistant, high-capacity batteries from wood pulp.
Researchers at MIT have now identified a neural circuit that they believe underpins decision-making in situations such as this, and have started looking into mice’s brains to better understand the biological processes that make us tick and help us pick.
We tend to think of the planets as static, enduring, and never changing. With the average human life spanning only decades, we can be forgiven that the dimension of time in which geological processes take place goes a bit over our heads. However, recent images captured by satellites showing the birth of two volcanic islands published in a study by Nature Communications are a powerful reminder that the Earth is a planet alive under its crust as well as above.
Tasmania’s Derwent River has put on a garb of surreal blue these past few nights as blooms of bioluminescent plankton light up the dark waters. But while photographers scramble to catch breathtaking pictures, scientists point to the more dire implications of the invasion of these tiny organisms so far south.
