| Follow the radio waves to find hidden exomoons Posted: 11 Aug 2014 02:02 PM PDT Scientists hunting for life beyond Earth have discovered more than 1,800 planets outside our solar system, or exoplanets, in recent years, but so far, no one has been able to confirm an exomoon. Now, physicists believe following a trail of radio wave emissions may lead them to that discovery. |
| Reconstructions show how some of the earliest animals lived -- and died Posted: 11 Aug 2014 02:02 PM PDT A bizarre group of uniquely shaped organisms known as rangeomorphs may have been some of the earliest animals to appear on Earth, uniquely suited to ocean conditions 575 million years ago. A new model has resolved many of the mysteries around the structure, evolution and extinction of these 'proto animals.' |
| Trapped atmospheric waves triggering more weather extremes: Trend expected to continue Posted: 11 Aug 2014 02:01 PM PDT Weather extremes in the summer -- such as the record heat wave in the United States that hit corn farmers and worsened wildfires in 2012 -- have reached an exceptional number in the last ten years. Human-made global warming can explain a gradual increase in periods of severe heat, but the observed change in the magnitude and duration of some events is not so easily explained. |
| Bioengineers create functional 3-D brain-like tissue: Tissue kept alive for months Posted: 11 Aug 2014 12:11 PM PDT Bioengineers have created three-dimensional brain-like tissue that functions like and has structural features similar to tissue in the rat brain and that can be kept alive in the lab for more than two months. The tissue could provide a superior model for studying normal brain function as well as injury and disease, and could assist in the development of new treatments for brain dysfunction. |
| 'Worm pill' could ease autoimmune disease symptoms Posted: 11 Aug 2014 09:51 AM PDT Experts believe a molecule in parasitic worms could help explain why worm infections can effectively treat a range of autoimmune diseases, including multiple sclerosis, psoriasis, rheumatoid arthritis and lupus. The study successfully identified peptides from parasitic worms that suppress the body's immune response. Researchers believe this could pave the way for a new drug containing the peptide to provide relief from the symptoms of autoimmune diseases. |
| How fast you drive might reveal exactly where you are going Posted: 11 Aug 2014 09:50 AM PDT Some drivers are letting auto insurance companies monitor their driving habits in return for a premium discount, but these drivers may not know that the information could reveal where they are driving. Engineers have shown that even without GPS or other location-sensing technology, a driver could reveal where he or she traveled with no more information than a starting location and a steady stream of data that shows how fast the person was driving. |
| Megascale icebergs ran aground near Greenland in last 800,000 years Posted: 11 Aug 2014 09:49 AM PDT Scientists have found between Greenland and Spitsbergen the scours left behind on the sea bed by gigantic icebergs. "Whenever icebergs run aground, they leave scours on the seabed. Depending on their depth and location, those markings may continue to exist over long periods of time," explained the lead author. Found at a depth of 1,200 metres, the newly found five lineaments are the deepest iceberg scours found to date in the Arctic. The scours are as much as four kilometres long and 15 metres in depth. |
| Posted: 11 Aug 2014 09:48 AM PDT A new model shows how early black holes could have grown to billions of times the mass of our sun. These giant bodies -- quasars -- feed on interstellar gas, swallowing large quantities of it non-stop. Thus they reveal their existence: The light that is emitted by the gas as it is sucked in and crushed by the black hole's gravity travels for eons across the Universe until it reaches our telescopes. Looking at the edges of the Universe is therefore looking into the past. These far-off, ancient quasars appear to us in their "baby photos" taken less than a billion years after the Big Bang: monstrous infants in a young Universe. |
| Solving a sticky problem with fetal surgery using a glue inspired by the sandcastle worm Posted: 11 Aug 2014 09:43 AM PDT In creating an adhesive patterned after glue produced by the lowly underwater sandcastle worm, researchers are reporting that they may have solved the problem of premature births that sometimes result from fetal surgery. It also could open up numerous opportunities to safely perform more complex fetal surgeries in the future. |
