Findings have shown that an experimental HIV-1 vaccine regimen is well-tolerated and generated comparable and robust immune responses against (Human Immunodeficiency Virus) HIV in healthy adults and rhesus monkeys. Also, another separate research has shown that higher levels of Plasmodium falciparum antibodies are protective against severe malaria in children living in Papua New Guinea. Children who have […]
The risk of human-made earthquakes due to fracking is greatly reduced if high-pressure fluid injection used to crack underground rocks is 895m away from faults in the Earth’s crust, according to new research. The recommendation, from the ReFINE (Researching Fracking) consortium, is based on published microseismic data from 109 fracking operations carried out predominantly in […]
Electric vehicle motors turn with the help of magnets made from rare-earth elements (black). Credit: Shin-Etsu Chemical The rise of electric vehicles is threatening supplies of a host of the earth’s elements. Cobalt and lithium for batteries are getting most of the attention, but rare earths for electric motors are also a pinch point. Now, […]
Nearly 100 planets orbiting stars outside our solar system have been discovered by scientists. Researchers at the Technical University of Denmark’s National Space Institute analysed hundreds of potential exoplanets from data provided by the Kepler spacecraft. Out of 275 candidate planets, scientists confirmed 95 were exoplanets. The spacecraft, which is on the K2 mission to […]

Feb. 4 is World Cancer Day, an annual opportunity to raise awareness of cancer and encourage its prevention, detection and treatment. In the area of detection, Faith Lapidus reports that researchers at the Johns Hopkins Kimmel Cancer Center in Baltimore, Maryland, are developing a blood test that screens for eight different types of cancer.
For dentists, a cavity is a conundrum—in order to save the tooth they must further damage it. Currently, the primary way to treat a cavity is to excavate the decay and the surrounding area before filling the resulting crater with a durable surrogate material such as metal, plastic or glass cement. But what if instead […]
A Westpac Little Ripper drone helped rescue two teens off the coast of Australia by dropping a flotation device to them. (Credit: Westpac Little Ripper) Last week’s sea rescue of Australian swimmers by an Unmanned Aerial Vehicle (UAV) is just the start of a robotics revolution. On January 18, an Australian lifeguard piloted a drone over the […]
