Federal officials say there is no island of debris from the 2011 Japanese tsunami floating toward the United States.
A Russian rocket soared into the cosmos Thursday carrying the Sochi Olympic torch and three astronauts to the International Space Station ahead of the first-ever spacewalk for the symbol of peace.
Despite a 12-year action plan calling for reducing the hypoxia zone in the Gulf of Mexico, little progress has been made, and there is no evidence that nutrient loading to the Gulf has decreased during this period. University of Illinois researchers have identified some of the biophysical and social barriers to progress and propose a way forward.
Singapore Prime Minister Lee Hsien Loong's official website was hacked Thursday by apparent members of activist group Anonymous after he vowed to hunt down anyone who attacks the city-state's technological network.
One of biology's most fundamental processes is something called transcription. It is just one step of many required to build proteins—and without it life would not exist. However, many aspects of transcription remain shrouded in mystery. But now, scientists at the Gladstone Institutes are shedding light on key aspects of transcription, and in so doing are coming even closer to understanding the...
Today's fourth and eighth graders are doing better than their predecessors in math and reading. But it's too early to start celebrating.
While tracking white-lipped peccaries and gathering environmental data in forests that link Brazil's Pantanal and Cerrado biomes, a team of researchers from the Wildlife Conservation Society and a local partner NGO, Instituto Quinta do Sol, discovered ancient cave drawings made by hunter-gatherer societies thousands of years ago.
Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University's Pratt School of Engineering have designed a power-harvesting device with efficiency similar to that of modern solar panels.
From Cal Ripkin, Jr., to MLK to Robert Downey, Jr., finding men named after their fathers is easy. Children named after men in the family – with so-called patronyms – are common around the world. But what about matronymns – names for a mother or grandmother? New research shows that matronymns are rare and that family naming trends follow a regional pattern in the United States: People in...
Super-Typhoon Haiyan was lashing the central and southern Philippines on Nov. 7 bringing maximum sustained winds of a Category 5 hurricane. NASA is providing visible, infrared and microwave satellite data to forecasters and warnings are in effect for the Philippines and Micronesia as Haiyan moves west.
Inside every plant cell, a cytoskeleton provides an interior scaffolding to direct construction of the cell's walls, and thus the growth of the organism as a whole. Environmental and hormonal signals that modulate cell growth cause reorganization of this scaffolding. New research led by Carnegie's David Ehrhardt provides surprising evidence as to how this reorganization process works, with...
Using three dimensional modeling techniques, advanced computer simulation and next generation sequencing technology, faculty at the University of Massachusetts Medical School (UMMS) and the Massachusetts Institute of Technology (MIT) have resolved a long-standing debate that has consumed scientists ever since chromosomes were first observed under the light microscope by Walther Flemming in 1878.
Changes are already happening to Earth's climate due to the burning of fossil fuels, deforestation and large-scale agriculture. As changes get more pronounced, people everywhere will have to adjust. In this week's issue of the journal Science, an international group of researchers urge the development of science needed to manage climate risks and capitalize on unexpected opportunities.
A Tesla Model S electric car caught fire this week after hitting road debris on a Tennessee freeway, the third fire in a Model S in the past five weeks.
Scientists at the University of Oulu, Finland, and at the Helmholtz Center Berlin (HZB) have shown the way to new directions in drug development against African sleeping sickness and other tropical parasitic infections. This was based on the structural analysis of the enzyme thiolase, which plays a central role in lipid metabolism in the parasite that causes sleeping sickness. The researchers...
Brazil and Germany are presenting a resolution to the U.N. General Assembly urging all countries to extend internationally guaranteed privacy rights to the Internet and other electronic communications.
A joint research led by the Smithsonian Institution (US), Saint Louis University (US) and Universidad de Los Andes (Venezuela) resulted in the discovery of an exciting new species from the daisy family. The two expeditions in the paramos high up in the Venezuelan Andes were crowned by the discovery of the beautiful and extraordinary, Coespeletia palustris. The study was published in the open...
(Phys.org) —Astronomers using NASA's Hubble Space Telescope have identified what they can only describe as a never-before-seen "weird and freakish object" in the asteroid belt that looks like a rotating lawn sprinkler.
In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report that the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires.
Depending on the environment in which the worm grows, the larva of the roundworm Pristionchus pacificus develops into either a wide-mouthed predator or a narrow-mouthed bacteria eater. A team of researchers at the Max Planck Institute for Evolutionary Biology in Tübingen, Germany, headed by Ralf J. Sommer have now discovered a developmental biological switch that determines the worm's mouth form....
Recently, researchers have been developing a new type of laser that combines photons and plasmons (electron density oscillations) into a single radiation-emitting device with unique properties. In particular, nanoscale photon-plasmon lasers can emit light that is more tightly confined than the light emitted by lasers that use only photons.
Mayo Clinic researchers have shown that a molecule called Cul4 helps to deposit DNA-packaging histone proteins onto DNA, an integral step in cramming yards of genetic code into compact coils that can fit into each cell. When DNA isn't packaged correctly, it can lead to the genomic instability characteristic of many forms of cancer.
Tricking algae's biological clock to remain in its daytime setting can dramatically boost the amount of valuable compounds that these simple marine plants can produce when they are grown in constant light.
Scientists at University of Copenhagen and University of Edinburgh have identified a core set of functionally relevant factors which regulates embryonic stem cells' ability for self-renewal. A key aspect is the protein Oct4 and how it makes stem cells stick together. The identification of these factors will be an important tool in devising better and safer ways of making specialised cells for...
