You’ll want to look up at the night sky Monday, because the much-anticipated “Christmas Star” is set to be at its brightest.The “Christmas Star” in a nickname that’s been given to the astronomical event when Jupiter and Saturn will get so close together, they’ll be especially vibrant and visible to the naked eye.During this “Great Conjunction,” the two planets will be the closest they’ve been to each other in nearly 400 years and it’s been about 800 years since the alignment occurred at night, allowing everyone around the world to witness it.Monday night, NASA says Jupiter and Saturn will appear so close that a pinkie finger at arm’s length will easily cover both planets in the sky.Those trying to catch a glimpse of the conjunction are encouraged to look toward the southwest sky just after sunset. NASA says you should find a spot with an unobstructed view of the sky, like a field or park. The planets can be seen with the unaided eye, but if you use binoculars or a telescope, you may be able to see Jupiter’s four large moons.Though from our vantage point, the planets will appear very close together, NASA says they’ll actually remain hundreds of millions of miles apart in space. The conjunction is also happening on the same day as the winter solstice, but the timing is merely a coincidence.“Conjunctions like this could happen on any day of the year, depending on where the planets are in their orbits,” said Henry Throop, astronomer in the Planetary Science Division at NASA Headquarters in Washington. “The date of the conjunction is determined by the positions of Jupiter, Saturn, and the Earth in their paths around the Sun, while the date of the solstice is determined by the tilt of Earth’s axis. The solstice is the longest night of the year, so this rare coincidence will give people a great chance to go outside and see the solar system.” 1874

World leaders in obesity research are optimistic about new guidelines out of Canada, which take a more holistic approach to diagnosing and treating obesity.One critical point is for doctors to stop relying on a person's body mass index alone for diagnosis.“Body mass index tells me how big you are. It doesn't tell me how sick you are,” said Dr. Arya Sharma, Scientific Director of Obesity Canada. “So, you can have two people with the exact same BMI numbers, two people, they are both 35, one person has sleep apnea, diabetes, hypertension, fatty liver disease, infertility whatever, and the next person with that body mass index has none of those problems.”Sharma says under these new guidelines, they are concerned that more people could be classified as obese. A person might fall under the BMI number for obesity but still have weight-related health issues.Currently, about 30% of Canadians are obese. In the United States, it’s about 42%.The head of the U.S. National Center for Weight and Wellness applauds the new approach.“That very well may be lead to a seminal shift in how the general medical population addresses obesity and for that, I think they really deserve a lot of credit,” said Dr. Scott Kahan, Director of the National Center for Weight and Wellness.Another critical issue the new guidelines address is weight bias among health professionals and people living with obesity.“Patients also tend to blame themselves, so they have an internalized weight bias, so the patients also think, ‘so this is my fault and I’ve done this to myself,’” said Sharma.Doctors say your body fights back against weight loss biologically, which is why Sharma says obesity is a chronic disease for which there is no cure but can be managed. And today, there are more proven treatments than ever, not diets.“The only reason why medication and surgery have much better long-term results is because they actually change the biology in the sense to make it much harder for the body to defend its weight,” said Sharma.Obesity is a complex disease that can be caused by genetics, psychological or environmental factors among others. 2133

early Sunday morning that left a pizza delivery driver dead on Cleveland's East Side.Officers responded to the scene around 12 a.m. local time after receiving a call that a man had been shot, according to police.Once on scene, officers found a man in a vehicle who had been shot and had crashed into two parked cars, police said.Officers and fire crews administered first aid to the man until EMS arrived.The man, identified as Daniel A. Scott, 28, of Cleveland, was pronounced dead at the scene, according to EMS.The man, who was in his 30s, was delivering pizza for Papa John’s, police said.The delivery driver was parked in front of a home when two men pulled up to him in a red car, exited the car and fired at him from both sides of his car, according to police.Police said the two men then fled the scene.The delivery driver’s car traveled a short distance from where he was parked and crashed into the two parked cars, according to police.The homicide unit responded to the scene and the incident is currently under investigation.Police said they have not made any arrests and the suspects have not yet been identified.This story was originally published by Camryn Justice of 1185

-- and its wider implications for human mental health treatment -- was found in their poop, per new findings published in Behavioural Brain Research.Rats are better drivers when they're mentally stimulatedKelly Lambert, study author and head of the University of Richmond's Lambert Behavioral Neuroscience Laboratory, trained two groups of young rats: One bunch raised in an "enriched environment" with toys, ladders, balls and pieces of wood designed to spark mental stimulation, and another reared in a standard, unexciting lab cage.The rats learned to enter a custom "rat-operated vehicle," or ROV, adorably constructed from a one-gallon plastic container turned on its side.Once inside, the rat racers would stand on an aluminum plate and press on a copper bar that would trigger the wheels' motor. They'd hold down on the bar until they propelled their tiny car to the end of their enclosure, where they collected their reward: Froot Loops.When it came time to drive, the rats who played with ladders, balls and toys were more adept at operating and steering the ROV, thanks to the neuroplasticity (their brains' ability to change over time) triggered by their environment. Their unstimulated cage counterparts effectively "failed their driving test," Lambert said.Hormones found in their feces showed improved emotional resilienceIn sifting through their fecal matter, Lambert found both groups of rats trained to drive secreted higher levels of corticosterone and DHEA, hormones that control stress responses.Corticosterone is a hormone animals could secrete in high-stakes scenarios like running from a wild animal or defending themselves from predators, but it can also be expressed in lower-risk tasks like doing taxes or worrying about a loved one (though rats likely aren't advanced enough to form a government, let alone impose taxes on fellow rats).DHEA acts as a sort of "buffer," Lambert said, when corticosterone becomes toxic -- that is, when it can't be turned off in a reasonable amount of time, creating prolonged stress.It's evidence that mastering a complex task, like driving a car, bolstered the rats' emotional resilience."It is likely that driving gives the rats a sense of control over their environment," she said. "In humans, we would say that it enhances a sense of agency or self-efficacy."What have rats got to do with human health?The brains of humans and rats share nearly all of the same areas and neurochemicals -- they're just smaller in rodents. And though humans are certainly more complex than rats, Lambert said there are "universal truths" in how both species' brains interact within their environment to maintain optimal mental health.So these results have implications for human health, too (and no, they don't mean rats will drive alongside people in tiny lanes on highways). Emotional resilience is one of the first lines of defense against mental illnesses like depression, she said, and learning what behaviors build that up could clue physicians in on how to treat those illnesses in humans.It's a concept Lambert refers to as "behaviorceuticals," activities that release hormones that can ward off prolonged stress brought on by corticosterone."Anything that reduces stress can build resilience against the onset of mental illness," she said.The activity can be something as simple as knitting, or in rats' case, learning to drive a car. Just engaging hands, paws and brains of varying sizes can enhance a participant's sense of control. 3489
