Is Antimatter a Viable Starship Fuel?

Hope springs eternal for die-hard Star Trek fans that scientists will one day build an actual, working antimatter propulsion engine similar to the one that powers the fictional starship Enterprise.

China Volcano Shows Signs of Unrest

A very hazardous volcano at the border of China and North Korea is growing more active, and might erupt in the next few decades, researchers studying the area...

Archaeologists unearth 4,200-year-old fortification, unique in continental Europe

The archaeological excavations carried out this year at the site of La Bastida (Totana, Murcia, in Spain) have shed light on an imposing fortification system, unique for its time. The discovery, together with all other discoveries made in recent years, reaffirm that the city was the most advanced settlement in Europe in political and military terms during the Bronze Age (ca. 4,200 years ago), and...

Bionengineers introduce "Bi-Fi": The biological Internet

(Phys.org)—If you were a bacterium, the virus M13 might seem innocuous enough. It insinuates more than it invades, setting up shop like a freeloading houseguest, not a killer. Once inside it makes itself at home, eating your food, texting indiscriminately. Recently, however, bioengineers at Stanford University have given M13 a bit of a makeover.

Breakthrough in kitchen furniture production: Biocomposites challenge chipboard

Biocomposites challenge chipboard as furniture material. Researchers at VTT Technical Research Centre of Finland have developed a kitchen furniture framework material from plastic polymers reinforced with natural fibre. The new material reduces raw materials consumption by 25 per cent and the carbon footprint of production by 35 per cent.

Nature's misfits: Reclassifying protists helps us understand how many species remain undiscovered

Since the Victorian era, categorizing the natural world has challenged scientists. No group has presented a challenge as tricky as the protists, the tiny, complex life forms that are neither plants nor animals. A new reclassification of eukaryotic life forms, published in the Journal of Eukaryotic Microbiology, draws together the latest research to clarify the current state of protist diversity...

One Degree Imager: Bigger, sharper images to be refined, processed and stored at IU

(Phys.org)—Recording light from millions of light years away and then sending it to the Indiana University Data Center at the corner of 10th Street and the State Road 45/46 Bypass, a new camera at Kitt Peak National Observatory in Arizona's Sonoran desert will image an area of sky five times that of the full moon, yet still focus at the equivalent of seeing a baseball from 30 miles away.

Retiring during economic booms could cause financial hardships for retirees, study finds

The recent economic downturn and volatile financial markets have drastically reduced the retirement accounts of many current and future retirees. In a new study, a University of Missouri financial expert has found that many Americans choose to retire when the economic markets are peaking, an action that can, ironically, cause major problems for the long-term financial stability of retirees.
