Research tests range of electrical frequencies that help heal chronic wounds

Naturally occurring electricity in our cells is key to how our bodies function, and that includes the healing of wounds. And externally applied low-amplitude electric fields have been shown to help hard-to-heal chronic wounds, like those associated with diabetes,

Turning algae into crude oil in less than an hour

It is known that algae-based biofuel most closely resembles the composition of the crude oil that gets pumped out from beneath the sea bed but now, researchers at the U.S. Department of Energy's Pacific Northwest National Laboratory in Richland,

Astronomers find solar storms behave like supernovae

Researchers at the UCL studying details of Coronal Mass Ejections (CMEs) have noticed that those eruptions have a surprising twin in the depths of space: the tendrils of gas in the Crab Nebula, which lie 6500 light-years away and are millions of

No increase in global temperature variability despite changing regional patterns, study

In a paper published in Nature several months ago, Huntingford et al. (2013) write "there is considerable interest in determining whether global warming is increasing climate variability," due to the concerns of some scientists that an increase in

Peru's Manu National Park sets new biodiversity record

Park and buffer zone host 287 species of reptiles and amphibians, the highest number anywhere. Peru's treasured Manu National Park is the world's top biodiversity hotspot for reptiles and amphibians, according to a new survey published last week by

Artificial leaf jumps developmental hurdle

In a recent early online edition of Nature Chemistry, ASU scientists, along with colleagues at Argonne National Laboratory, have reported advances toward perfecting a functional artificial leaf. Designing an artificial leaf that uses solar energy to convert

Increase in Arctic cyclones linked to climate change, new study shows

Winter in the Arctic is not only cold and dark, it is also storm season when hurricane-like cyclones traverse the northern waters from Iceland to Alaska. These cyclones are characterized by strong localized drops in sea level pressure, and as Arctic-wide decreases in

Rewriting the text books: Scientists crack open 'black box' of development

We know much about how embryos develop, but one key stage – implantation – has remained a mystery. Now, scientists from Cambridge have discovered a way to study and film this 'black box' of development. Their results – which will lead to the

IBEX research shows influence of galactic magnetic field extends well beyond our solar system

In a report published yesterday, new research suggests the enigmatic “ribbon” of energetic particles discovered at the edge of our solar system by NASA’s Interstellar Boundary Explorer (IBEX) may be only a small sign of the vast influence of the

Mass death of dinosaurs in northern China caused by volcanic eruption

Well preserved fossils found at the Jehol Biota, northeast China, suggest that a volcanic eruption in the Cretaceous Era may have caused the mass death of dinosaurs in that region. The fossil formations were similar to remains uncovered from the Roman city of

From artificial to natural, the food industry makes a major shift

Extracts from algae, rosemary and monk fruit could soon replace synthetic ingredients and food additives such as Blue No. 1, BHT and aspartame that label-conscious grocery shoppers are increasingly shunning. Research is enabling this shift from artificial colors,

Editing the human genome one letter at a time

Scientists at the Gladstone Institutes have found a way to efficiently edit the human genome one letter at a time. The discovery is boosting researchers' ability to model human disease, and paving the way for therapies that cure disease by fixing these

Global warming actually decreases storm activity, says science paper

Current weather patterns are changing, we are constantly told by everyone from President Obama during his most recent State of the Union Address on down through various academic circles. And few of us dispute that; weather, after all, changes over time, as

Greenland’s fastest glacier reaches record speeds - Jakobshavn Glacier

Jakobshavn Isbræ (Jakobshavn Glacier) is moving ice from the Greenland ice sheet into the ocean at a speed that appears to be the fastest ever recorded. Researchers from the University of Washington and the German Space Agency (DLR) measured the dramatic speeds

Aluminum induces neurotoxicity by altering mitochondria of brain cells

Aluminum's role in causing neurotoxicity and contributing to a number of degenerative diseases, including Alzheimer's disease, has been widely discussed and is supported by a number of studies, though the exact mechanism remains inconclusive. Now, scientists

Asteroid diversity points to a "snow globe" solar system

Our solar system seems like a neat and orderly place, with small, rocky worlds near the Sun and big, gaseous worlds farther out, all eight planets following orbital paths unchanged since they formed. However, the true history of the solar system is more riotous.
