25 Hurricanes Hit The USA In The 1880s

Next Big Future: Was there global warming in the 1880s? Because 25 hurricanes hit the USA in that decade

A total of 293 Atlantic tropical cyclones have produced hurricane-force winds in every state along the Atlantic Ocean and Gulf of Mexico, as well as Pennsylvania. Florida more than any other hurricane.

CNN and Jeffrey Sachs are blaming the three hurricanes that hit the USA this year on climate change. The 1880s were the most active hurricane decade for the United States, with a total of 25 hurricanes affecting the nation. Does this mean that 1880s had the most climate change hurricanes?

City Lab: Amazon Whittles Down List of HQ2 Contenders to 20 Finalists

The list skews toward larger cities and metropolitan areas along the Eastern corridor, stretching as far north as Toronto and as far south as Miami. And it looks like some of the economic incentives might be paying off.

We’re one step closer to finding out where Amazon’s coveted HQ2 will call home. The company has whittled down the list of 238 cities to 20, it announced Thursday morning. The list of finalists skews toward larger cities and metropolitan areas along the Eastern corridor, stretching as far north as Toronto and as far south as Miami.

This Oil Spill Is Like No Other

The Atlantic: The World Has Never Seen an Oil Spill Like This

A tanker that sank off the Chinese coast was carrying “condensate,” a mix of molecules with radically different properties than crude.

Over the last two weeks, the maritime world has watched with horror as a tragedy has unfolded in the East China Sea. A massive Iranian tanker, the Sanchi, collided with a Chinese freighter carrying grain. Damaged and adrift, the tanker caught on fire, burned for more than a week, and sank. All 32 crew members are presumed dead.

Meanwhile, Chinese authorities and environmental groups have been trying to understand the environmental threat posed by the million barrels of hydrocarbons that the tanker was carrying. Because the Sanchi was not carrying crude oil, but rather condensate, a liquid by-product of natural gas and some kinds of oil production. According to Alex Hunt, a technical manager at the London-based International Tanker Owners Pollution Federation, which assists with oil spills across the world, there has never been a condensate spill like this.

China Wants To Be A Leading Player In Artificial Intelligence

BBC: Tech Tent: China's AI ambitions

On this week's Tech Tent we hear why China's determination to be a leading player in artificial intelligence could lead to tensions with the United States.

We have two other reports on this week's programme. In a compelling interview with Jane Wakefield, YouTube star Chrissy Chambers talks about her court battle against a former boyfriend who uploaded explicit videos featuring her to a pornography website. Her victory is being seen as a key moment in the battle against the internet scourge known as revenge porn.

CSN Editor: China has the resources, people, and ambition to be a leader in AI. I would take them very seriously.

These Small Rockets Are Designed To Launch Small Satellites

Wired: The Little Rocket That Could Sends Real Satellites to Space

The launch company Rocket Lab has amusing names for its missions. The first, in May, was called “It’s a Test” (it was). When the staff debated what to call the second launch of their diminutive Electron rocket, so sized (and priced) specifically to carry small satellites to space, they said, “Well, we’re still testing, aren’t we?”

They were. And so “Still Testing” became the name of Rocket Lab’s second launch, which took place on January 20, at around 8:45 pm Eastern Standard Time. In December, the company canceled multiple attempts before rescheduling the launch window for 2018. The livestreamed rocket lifted off from the Mahia Peninsula in New Zealand, headed for someplace with an even better view.

CSN Editor: They want the small payload-satellite niche. More signs on how the commercialization of space continues.

Blood Test Can Now Detect 8 types Of Common Cancers

The Guardian: Blood test could use DNA to spot eight of the most common cancers, study shows

DNA and biomarkers could be used to detect and identify cancers, including five types for which there is currently no screening test.

Scientists have made a major advance towards developing a blood test for cancer that could identify tumours long before a person becomes aware of symptoms.

The new test, which is sensitive to both mutated DNA that floats freely in the blood and cancer-related proteins, gave a positive result approximately 70% of the time across eight of the most common cancers when tested in more than 1,000 patients.

In the future, such a test could be used in routine screening programmes to significantly increase the proportion of patients who get treatment early, at a time before cancer would typically show up on conventional scans.

How Much Water Should A Person Drink?

Live Science: How Much Water Do You Really Need To Drink?

You are what you eat — but if you want to get literal about it, you are mostly what you drink. So, how much of that should be water?

About 60 percent of the average adult human body is made of water, according to a National Institutes of Health report. This includes most of your brain, heart, lungs, muscles and skin, and even about 30 percent of your bones. Besides being one of the main ingredients in the recipe for humankind, water helps us regulate our internal temperature, transports nutrients throughout our bodies, flushes waste, forms saliva, lubricates joints and even serves as a protective shock absorber for vital organs and growing fetuses.

CSN Editor: The answer is .... Drink up when you're thirsty, and drink more when you sweat more. Your body will take it from there.
