READ MORE In their study, the LMU researchers confirmed the presence of magnetic particles in human brains. The particles were found primarily in the cerebellum and the brainstem, and there was striking asymmetry in the distribution between the left and right hemispheres of the brain. “The human brain exploits asymmetries in sensory responses for spatial orientation, and also for sound-source localization,” Schmitz explains. The asymmetric distribution of the magnetic particles is therefore compatible with the idea that humans might have a magnetic sensor. But in all probability, this sensor is much too insensitive to serve any useful biological function, he adds. Furthermore, the chemical nature of the magnetic particles remains unknown. “We assume that they are all made of magnetite (Fe 3 O 4 ), but it is not yet possible to be sure,” says Gilder. The study was funded by the Volkswagen Foundation’s “Experiment!” program, which is designed spec...

READ MORE Now biologists at the University of Cincinnati are studying whether that ability translates to the more humdrum-looking wolf spiders that are muted browns and tans instead of electric blue, fiery orange and stoplight red. UC biology professor George Uetz and his students presented their work in June at the American Arachnological Society meeting at the University of Michigan. “The assumption was wolf spiders don’t pay attention to color. But we found that isn’t really true,” Uetz said. “We need to look more closely at the neurobiology of their eyes. We need to understand what their retinas do.” Like most spiders, wolf spiders have four pairs of eyes, some of which have a reflective lens called a tapetum that sparkles in bright light. If you are an arachnophobe and want a reason never to go in your backyard again, try shining an LED light there some evening and see all the little predators staring back. Wolf spiders are quickly becoming a mod...

READ MORE An international team of researchers describes how zebra finches produce songs in the journal Chaos , from AIP Publishing. Using electromyographic (EMG) signals, researchers tracked the activity of one of the main muscles involved in creating sound, the syringealis ventralis (vS) muscle. They then used the data from this muscle to create a synthetic zebra finch song. “The activity of this muscle provided us information on gating, when the sound starts or ends,” said Juan Döppler, one of the researchers and a doctoral student at the University of Buenos Aires. “What’s interesting is that when the bird is asleep, despite lacking the airflow necessary to produce sound, this muscle also activates and shows electrical activity, similar to the activity it shows while singing.” The researchers inserted pairs of bipolar electrodes into the vS muscle of five adult zebra finches. It was previously assumed that the vS muscle was primarily involved in fr...

READ MORE Partnering with volunteers in the University’s Pennsylvania Master Well Owner Network, researchers tested water samples from 26 households with private wells in nine counties in the basin of the West Branch of the Susquehanna River. All samples were analyzed for seven over-the-counter and prescription pharmaceuticals: acetaminophen, ampicillin, caffeine, naproxen, ofloxacin, sulfamethoxazole and trimethoprim. At least one compound was detected at all sites. Ofloxacin and sulfamethoxazole — antibiotics prescribed for the treatment of a number of bacterial infections — were the most frequently detected compounds. Caffeine was detected in approximately half of the samples, while naproxen — an anti-inflammatory drug used for the management of pain, fever and inflammation — was not detected in any samples. “It is now widely known that over-the-counter and prescription medications are routinely present at detectable levels in surface and groundwat...

READ MORE But passing gun legislation in Congress has proved nearly impossible and the House of Representatives is already gone for its August recess, which means no bill can be taken up until September. While the lawmakers said they are soliciting Republican support, at least one Republican, Senator Mike Rounds of South Dakota, said it would be extremely difficult to stop the proliferation of the weapons. “This is a new technology which you’re not going to put back into the bottle, it is there,” Mr. Rounds said, adding that the smarter course would be to “create new technologies and utilize new technologies” — such as metal detectors that could also recognize plastic — in schools, airports and other public places. It is not clear what Mr. Trump is prepared to do in the wake of his tweet. The president has been a staunch supporter of gun rights and has repeatedly said that he is the best friend of the National Rifle Association, which contribute...

READ MORE While not directly related, Russia looms over the case. The charges against Mr. Manafort are not related to Russia’s interference in the 2016 presidential election or to attempts by Russian emissaries to make inroads into the Trump campaign, which Mr. Manafort led for three months before he was forced out because of allegations about his work for pro-Russian interests in Ukraine. Nonetheless, the trial is being carefully watched because of Mr. Manafort’s role as the chairman of the Trump campaign and his long standing ties with pro-Russia businessmen and politicians, which he developed over a decade of political consulting work in Ukraine. Catching up on the Paul Manafort trial? Here is a rundown of the stakes and answers to some FAQs. Judge Ellis has told lawyers for both sides that he will not allow politics or anti-Russian sentiment to taint the jury. And he has warned prosecutors and defense lawyers to steer clear of references to Russia as they present their...

READ MORE (Reuters) – MGM Resorts International ( MGM.N ) said on Tuesday it signed an agreement with the NBA to become the basketball league’s first sports betting partner. The multi-year deal with the NBA and WNBA will allow the casino chain to use their official names, logos and data streams across its hotels. The agreement is for three years and at least $25 million, ESPN reported. MGM shares rose 2.5 percent in late afternoon trading.
