Australian researchers have achieved groundbreaking results in a clinical trial using hookworms to reduce the symptoms of celiac disease.
Scientists have designed a new class of antibiotic which seeks and destroys resistance genes in bacteria.
A molecule used as a communication system by bacteria can be manipulated to prevent cancer cells from spreading, a study has demonstrated. "During an infection, bacteria release molecules which allow them to 'talk' to each other," said the lead author of the study. "Depending on the type of molecule released, the signal will tell other bacteria to multiply, escape the immune system or even stop spreading.".
Isaac Yonemoto is a chemist, but he’s been writing software code since he was a kid. He calls himself a “semi-recreational” programmer, and now, he’s running an experiment that combines this sideline with his day job. In short, he’s using open source software techniques to kickstart the world of cancer research.
A new study could debunk the theory that women living where rates of infectious disease are high prefer men with faces that shout testosterone when choosing a mate.
Apira Science's iGrow Hair Growth system is now available over-the-counter. The funky looking device uses lasers and LEDs to illuminate the scalp with red light, which according to the manufacturer is supposed to work.
Measurements by scientists at the Munich University of Technology have revealed tree growth rates have rapidly increased by 70 percent compared to 50 years ago. The scientists conducted their study on experimental forest plots which are well-controlled, and compared their data to historical data taken continuously since 1870.

1. After learning about the harmful effects of ocean-borne plastic, a group of fifth and sixth grade students persuaded Dunkin' Donuts to phase out the use of foam cups. These kids are superheroes.

It only took about half a century, but the once-rare Delmarva fox squirrel (Sciurus niger cinereus) now has a healthy population once again, placing it in a position to finally leave the protection of the Endangered Species Act (ESA). If that happens, this giant squirrel—which can reach an astonishing 75 centimeters in length—would join just 29 other species that have been declared recovered under the ESA.
Although the narwhal (Monodon monoceros) is well-known throughout popular culture, the purpose of its iconic tusk is not. The appendage—which is actually a single tooth that protrudes from the whale’s upper left jaw—can grow up to 2 to 3 meters in length and is found almost exclusively in males.
A team of researchers with members from Iceland, Sweden and Saudi Arabia has found evidence of chemical changes to underground well water prior to two different earthquakes that occurred in 2012 and 2013 in Iceland. In their paper published in the journal Nature Geoscience, the researchers acknowledge that their findings do not suggest that they have found a reliable earthquake precursor, but they do believe they may be on to something. S.E. Ingebritsen with the U.S. Geological Survey and M. Manga with the University of California, describe the research in a News & Views piece in the same journal issue and suggest that more such research be done.
The biggest mystery associated with the gods is why they came here in the first place. There are a variety of theories as to why an advanced civilization would come to the Earth. The one that often surfaces is that there were problems on their home world such as overpopulation, pollution, or a shortage of natural resources. These issues could have caused a group of explorers to leave their planet and seek out new life and new civilizations. It could be that their home world was destroyed and a lucky few managed to escape. Perhaps the Galactic Federation of Planets needed to create a way station between heaven (Asgard) and hell (Hel).
Mars was once awash with water. With the arrival of Nasa’s Maven mission at the red planet, we may finally be close to working out where it all went
New modeling studies from Carnegie's Alan Boss demonstrate that most of the stars we see were formed when unstable clusters of newly formed protostars broke up. These protostars are born out of rotating clouds of dust and gas, which act as nurseries for star formation. Rare clusters of multiple protostars remain stable and mature into multi-star systems. The unstable ones will eject stars until they achieve stability and end up as single or binary stars.
When the International Astronomical Union came up with an official definition of a planet in 2006, they booted Pluto out of the club and reclassified it as a dwarf planet. But some say the discovery of exoplanets requires that we revisit this definition and give Pluto a second chance.
One of the big questions in cosmology regards the shape of the universe. "Shape" in this case is not the distribution of galaxies, but rather the shape of space and time itself. In general relativity, space and time can be warped by masses (producing the effect of gravity), and it can be warped by dark energy (producing cosmic expansion). Knowing the shape of the cosmos lets us determine if it is finite in size or infinite, and whether it will expand forever or collapse back upon itself.
Physicists have found hints that the asymmetry of life — the fact that most biochemical molecules are ‘left-handed’ or ‘right-handed’ — could have been caused by electrons from nuclear decay in the early days of evolution. In an experiment that took 13 years to perfect1, the researchers have found that these electrons tend to destroy certain organic molecules slightly more often than they destroy their mirror images.
