As “Hypercarnivores", Humans Were Apex Predators For 2 Million Years
While many modern humans opt for a vegetarian or vegan diet, new research suggests that our ancestors obtained the majority of their nutrition from meat, and only diversified their food intake to include more plants at the very end of the Stone Age.

'Past a point of no return': Reducing greenhouse gas emissions to zero still won't stop global warming
Even if human-caused greenhouse gas emissions can be reduced to zero, global temperatures may continue to rise for centuries afterward, according to a scientific study published Thursday.
"The world is already past a point of no return for global warming," the study authors report in the British journal Scientific Reports. The only way to stop the warming, they say, is that "enormous amounts of carbon dioxide have to be extracted from the atmosphere."
The burning of fossil fuels such as oil, coal and gas release greenhouse gases such as carbon dioxide and methane into the atmosphere, causing global temperatures to increase and sea levels to rise.
The scientists modeled the effect of greenhouse gas emission reductions on changes in the Earth's climate from 1850 to 2500 and created projections of global temperature and sea level rises.

New study questions the effectiveness of colonoscopies
Colonoscopies are a dreaded rite of passage for many middle-age adults. The promise has been that if you endure the awkwardness and invasiveness of having a camera travel the length of your large intestine once every decade after age 45, you have the best chance of catching – and perhaps preventing – colorectal cancer. It’s the second most common cause of cancer death in the United States. Some 15 million colonoscopies are performed in the US each year.
Now, a landmark study suggests the benefits of colonoscopies for cancer screening may be overestimated.

West Nile virus and invasive mosquitos arrive in Shasta County
Positive tests from samples of adult mosquitos in the Anderson and Shingletown area confirm the West Nile virus has returned to Shasta county.
The Shasta Mosquito and Vector Control District (SMVCD) said in a press release Saturday that the positive tests came from routine collections as part of their surveillance program. The district is now attempting to decrease mosquito populations through ground treatments in areas where the positive mosquitos were found. They are also continuing their widespread mosquito trapping and testing to monitor virus activity.

Scientists baffled as Earth spins faster than usual
Scientists have warned that, if the rotation rate continues to speed up, we may need to remove a second from our atomic clocks.
“If Earth’s fast rotation continues, it could lead to the introduction of the first-ever negative leap second.”

Why Drinking Water All Day Long Is Not the Best Way to Stay Hydrated
Water is cheap and healthy. And drinking H2O is an effective way for most people to stay hydrated. The National Academy of Medicine recommends that adult women and men drink at least 91 and 125 ounces of water a day, respectively. (For context, one gallon is 128 fluid ounces.) But pounding large quantities of water morning, noon and night may not be the best or most efficient way to meet the body’s hydration requirements.
“If you’re drinking water and then, within two hours, your urine output is really high and [your urine] is clear, that means the water is not staying in well,” says David Nieman, a professor of public health at Appalachian State University and director of the Human Performance Lab at the North Carolina Research Campus. Nieman says plain water has a tendency to slip right through the human digestive system when not accompanied by food or nutrients. This is especially true when people drink large volumes of water on an empty stomach. “There’s no virtue to that kind of consumption,” he says.

Why You Should Stop Throwing Out Expired Food
While we no doubt could — and should — reduce waste overall, FoodPrint offers one surprising statistic that speaks to why we fail to use so much food: "An estimated 80% of Americans prematurely discard food due to confusion over the meaning of date labels." A similar issue was brought up by Vox. People throw away food because the label on the packaging says that we've passed the date for use. Originally, the labels were only meant for stores to know when they could stock which products. Customers, however, wanted to know what was on the labels, so it was made available to them.

Solar Panels Are Starting to Die, Leaving Behind Toxic Trash
Solar panels are an increasingly important source of renewable power that will play an essential role in fighting climate change. They are also complex pieces of technology that become big, bulky sheets of electronic waste at the end of their lives—and right now, most of the world doesn’t have a plan for dealing with that.
But we’ll need to develop one soon, because the solar e-waste glut is coming. By 2050, the International Renewable Energy Agency projects that up to 78 million metric tons of solar panels will have reached the end of their life, and that the world will be generating about 6 million metric tons of new solar e-waste annually. While the latter number is a small fraction of the total e-waste humanity produces each year, standard electronics recycling methods don’t cut it for solar panels. Recovering the most valuable materials from one, including silver and silicon, requires bespoke recycling solutions. And if we fail to develop those solutions along with policies that support their widespread adoption, we already know what will happen.

A Daily Baby Aspirin Has No Benefit For Healthy Older People
Many healthy Americans take a baby aspirin every day to reduce their risk of having a heart attack, getting cancer and even possibly dementia. But is it really a good idea?
Results released Sunday from a major study of low-dose aspirin contain a disappointing answer for older, otherwise healthy people.
"We found there was no discernible benefit of aspirin on prolonging independent, healthy life for the elderly," says Anne Murray, a geriatrician and epidemiologist at Hennepin Healthcare in Minneapolis, who helped lead the study.
