Safe livelihoods for informal gold miners in South and Southeast Asia
Safer ways for informal miners in South and Southeast Asia to prospect for gold will be investigated under an Australian Government grant won by The Australian National University (ANU) and Minelab.
Unusual material expands dramatically under pressure
If you squeeze a normal object in all directions, it shrinks in all directions. But a few strange materials will actually grow in one dimension when compressed. A team of chemists has now discovered a structure ...
Earth's gold came from colliding dead stars
We value gold for many reasons: its beauty, its usefulness as jewelry, and its rarity. Gold is rare on Earth in part because it's also rare in the universe. Unlike elements like carbon or iron, it cannot ...
Boosting immune therapy for cancer with nanoparticles
(Phys.org) —Activating the body's immune system to attack cancer and prevent it from recurring is one of the Holy Grails of cancer research because of its ability to specifically target cancer and to search almost anywhere ...
Nanoparticles help disrupt tumor blood supply, destroy tumors
(Phys.org) —In recent years, cancer researchers have been developing agents that destroy the blood vessels surrounding tumors with the goal of starving tumors to death. Some of these agents, such as tumor necrosis factor-alpha ...
Breakthrough could lead to 'artificial skin' that senses touch, humidity and temperature
Using tiny gold particles and a kind of resin, a team of scientists at the Technion-Israel Institute of Technology has discovered how to make a new kind of flexible sensor that one day could be integrated into electronic ...
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. ...
Dozens of mummies found in pre-Inca royal tomb in Peru
Polish and Peruvian archaeologists have discovered a royal burial chamber with 60 mummies and some 1,200 gold, silver and ceramic objects from over 1,000 years ago in Peru.
Researchers strike gold with nanotech vaccine
Scientists in the US have developed a novel vaccination method that uses tiny gold particles to mimic a virus and carry specific proteins to the body's specialist immune cells.
Gold probes may offer valuable insight into cancer
(Phys.org) —Nanoprobes made from gold could be used to predict people's cancer risk – and the effectiveness of treatments, following research by University of Strathclyde academics.
Researchers use nanoparticles to speed up or slow down angiogenesis
Researchers invent cleaner way to produce concrete
