A new toilet is headed to the International Space Station this week, in addition to new foods to grow and beauty products.The million toilet system is known as the Universal Waste Management System. It’s 65 percent smaller and 40 percent lighter than the toilet currently used on the space station.“I know it’s a toilet and I get a big laugh from my friends all the time, ‘Oh, he’s building a toilet.’ But it’s not just a toilet, it’s a titanium space toilet,” said Jim Fuller, Program Manager for the UWMS project at Collins Aerospace.That hefty price tag includes fans to create “gentle air flow to help collect waste in microgravity,” and will help NASA reach their “goal of 98 percent water recovery for deep space missions.” The new system can also handle larger crews, requires less maintenance, and better accommodates female astronauts. 856

A mysterious metal object has shown up along a northern San Luis Obispo County hiking trail.The monolith on Atascadero’s Pine Mountain has three sides and is 12-feet tall, according to City officials.While when the object was placed there or by who hasn't been revealed, locals say it was a recent addition.Pine Mountain is part of the Atascadero Land Preservation Society (ALPS), which says it doesn't have information on the monolith. Monolith structures are on the minds of many after the discovery of one in Utah last month. It was later removed by an unknown party. 578

A study released earlier this year conducted by university researchers from both the UK and US indicated that climate change is causing more extreme rainfall events from hurricanes, specifically among Caribbean islands.The study was authored by researchers from Bristol University in the UK and MIT in the US.The researchers said that the focus on the study was on extreme rainfall from hurricanes, like Hurricane Dorian which, stalled over the Bahamas last year.“Overall, the results suggest that the Eastern Caribbean region in particular (Puerto Rico and the Dominican Republic) is likely to benefit from a reduction in extreme hurricane precipitation events resulting from increased efforts to stabilize global warming,” the study reads, pointing to the Paris Climate Accord as a benchmark for minimizing the impact of extreme rainfall events from hurricanes.The research found that events like Hurricane Maria, which struck Puerto Rico in 2017, would happen twice as frequently if sea surface temperatures increase by 2 Celsius instead of 1.5 Celsius, which is the goal of the Paris Climate Accord.In the case of Hurricane Dorian, an event like that could strike the Bahamas four to five times more frequently if sea surface temperatures increase by 2 Celsius instead of 1.5 degrees. A seemingly small difference could be what saves thousands of lives and billions of dollars in damage.One of the study’s authors told CBS News there is particular concern that the impact of extreme rainfall events could occur over poorer island nations in the Caribbean."The findings are alarming and illustrate the urgent need to tackle global warming to reduce the likelihood of extreme rainfall events and their catastrophic consequences, particularly for poorer countries which take many years to recover," Emily Vosper, a researcher at the University of Bristol, told CBS News.The full study is available here. 1912

A nor'easter already closing schools and canceling thousands of flights Wednesday is set to bring record-setting snow to the region.The fourth nor'easter in three weeks will dump heavy snow, winds and even coastal flooding to some areas. It has potential to be one of the most significant and most disruptive snowstorms this late in the season, CNN meteorologists said.Snow has begun to fall and it will pick up while more than 70 million people are under a winter storm watch, warning or advisory from the southern Appalachians to Boston. 547

A massive cloud of Sahara Desert dust is blanketing the Caribbean as it heads toward the U.S. with a size and concentration that experts say hasn’t been seen in half a century. The thick dust cloud, known as the Saharan Air Layer, is making a 5,000 mile trip from the northern Africa desert to North and Central America along the east to west Trade Winds along the equator. The Saharan Air Layer is between 5,000 and 20,000 feet above the Earth's surface, and dust plumes travel over the Atlantic Ocean several times a year between spring and fall. This year's dust plume is thicker than normal, the concentration of particles in Puerto Rico are the highest in decades. Air quality across most of the Caribbean region fell to record “hazardous” levels Monday and experts who nicknamed the event the “Godzilla dust cloud” warned people to stay indoors and use air filters if they have one. 896
