A man bid $350,000 on a permit to kill an endangered black rhino in the African nation of Namibia last year. This week, Corey Knowlton, a 36-year-old Texan, bagged his rhino– and it was in the name of conservation.
It looks like a Slinky suspended in motion. Yet this photonics advancement– called a metamaterial hyperlens– doesn’t climb down stairs. Instead, it improves our ability to see tiny objects. The hyperlens may someday help detect some of the most lethal forms of cancer.
Sometimes a little damage can do a lot of good— at least in the case of iron-based high-temperature superconductors. Bombarding these materials with high-energy heavy ions introduces nanometer-scale damage tracks that can enhance the materials' ability to carry high current with no energy loss— and without lowering the critical operating temperature.
Stained and broken bones from 2,500 years ago have now provided some clue to the practices of ancient Mesoamerican cannibals, according to new research. The bones of 18 people discovered at a site just outside Mexico City have provided clues about how cannibals prepared their victims for meals.
Super Balls are toys beloved by children because of their extraordinary ability to bounce. Physicists love them for exactly the same reason. Drop a baseball on the floor and it will hardly bounce at all. Drop a Super Ball from shoulder height, and it will bounce back 92 percent of the way to the drop-off point.
The editors of Laboratory Equipment want you to start your week with a smile on your face, especially on a holiday. So, here’s a science joke you might like. Q: Why are abacuses so great?
Bacteria resistant to antibiotics are on the rise. There are different explanations for how these resistances are transferred. Now, researchers have found phages in chicken meat that are able to transfer antimicrobial resistance to bacteria.
About 90 percent of advanced prostate cancers have particular genetic mutations that can provide a target for cancer drugs. An international team of scientists say they have catalogued a comprehensive map of those mutations in metastatic prostate cancers. Their findings are a “Rosetta Stone” to breakthrough treatments of the disease.
America's largest tobacco companies must inform consumers that cigarettes were designed to increase addiction, but not that they lied to the public about the dangers of smoking, a federal appeals court ruled today. The ruling from the U.S. Court of Appeals for the District of Columbia Circuit is a partial win for cigarette makers in the long-running legal fight that began in the Clinton administration in 1999.
When it comes to magnets, a doctor’s trash is a physicist’s treasure. Researchers at a national lab recently acquired two decommissioned magnets from MRI scanners from hospitals that will find a new home as proving grounds for instruments used in high-energy and nuclear physics experiments.
Play a flute in Carnegie Hall, and the tone will resonate and fill the space. Play in in the Grand Canyon, and the sound will crash against the rock walls. The disparity is clear— to the modern listener, the instrument belongs in an auditorium. But, in the past, people sought echoes. The response of audiences and performers to acoustic characteristics is a function of their worldview, and it is as fluid as the environment they inhabit.
Researchers have shown that they can use a microfluidic cell-squeezing device to introduce specific antigens inside the immune system’s B cells, providing a new approach to developing and implementing antigen-presenting cell vaccines.
Wal-Mart is urging its thousands of U.S. suppliers to curb the use of antibiotics in farm animals and improve treatment of them. They are asking meat producers, eggs suppliers and others to use antibiotics only for disease prevention or treatment, not to fatten their animals. The guidelines also aim to get suppliers to stop using sow gestation crates and other housing that doesn't give animals enough space.
A team of researchers has discovered a certain type of soil bacteria can use their social behavior of outer membrane exchange to repair damaged cells and improve the fitness of the bacteria population as a whole.
The melting of inland ice in Antarctica has sped over five years– adding massive amounts of water to the rise of sea levels, according to new research. The Southern Antarctic Peninsula’s glaciers became destabilized in 2009– and the melting of ice shelves has accelerated ever since.
Welcome to Laboratory Equipment's new Friday series, In Case You Missed It (ICYMI), where we bring you three trending news stories from the week. A deadly dog flu, concerns about scientific publishing and a highway just for butterflies are up for review today.
