Researching new detectors for chemical, biological threats
Sandia National Laboratories scientists are thinking small, building on decades of sensor work to invent tiny detectors that can sniff out everything from explosives and biotoxins to smuggled humans.
New computational approaches speed up the exploration of the universe
How many different molecules can be created when you release one of the universe's most reactive substances, hydrogen cyanide, in the lab? And will the process create some particularly interesting molecules?
Lighting the way to the future
The highly inefficient incandescent light bulb is now a thing of the past, banned from European supermarket shelves in favour of more efficient lighting. The ban is part of the EU's strategy to reduce overall ...
Indian Ocean paradise island beset by shark controversy
The dangers of shark attacks are no secret for Georges, who as a kid was repeatedly warned to beware of the large predators lurking in the tropical waters off his native Reunion island.
The day before death: A new archaeological technique gives insight into the day before death
The day before the child's death was not a pleasant one, because it was not a sudden injury that killed the 10-13 year old child who was buried in the medieval town of Ribe in Denmark 800 years ago. The day ...
Researchers devise a way to measure volatile organic compound exchange in the atmosphere
Chemical reaction could streamline manufacture of pharmaceuticals and other compounds
Researchers at The University of Texas at Austin have discovered a new chemical reaction that has the potential to lower the cost and streamline the manufacture of compounds ranging from agricultural chemicals ...
Keep the Aspidistra flying
Grown for its ability to survive neglect, shady conditions and the effects of gas used for lighting, the Aspidistra was such a popular houseplant in late Victorian Britain that it came to represent – as novelist George ...
Lab-on-a-chip technology gets a flexible upgrade
Microfluidic devices move liquids through tiny, hair-sized pathways carved into glass slides and have distinct advantages over traditional laboratories when it comes to medical diagnostics. At these reduced ...
Researchers estimate over two million deaths annually from air pollution
Over two million deaths occur each year as a direct result of human-caused outdoor air pollution, a new study has found.
Clearing the air: The hidden wonders of indoor plants
It may come as a surprise but air pollution levels indoors are almost always higher than outside, even in busy city centres. Even more surprising is that indoor plants have the ability to mitigate high levels ...
Researchers warn of legacy mercury in the environment
Environmental researchers at Harvard University have published evidence that significant reductions in mercury emissions will be necessary just to stabilize current levels of the toxic element in the environment. ...
Caterpillars attracted to plant SOS
Plants that emit an airborne distress signal in response to herbivory may actually attract more enemies, according to a new study published in the open-access journal Frontiers in Plant Science .
Spinning up antibacterial silver on glass
The antibacterial effects of silver are well established. Now, researchers at Yonsei University in Seoul, Republic of Korea, have developed a technique to coat glass with a layer of silver ions that can prevent growth of ...
