When a country or a company makes a promise to reduce carbon emissions, respect fishing quotas or cut toxic output, how can we be sure they’ll keep their word?

The truth is, it’s often extremely hard. But a new initiative — Global Ledger — led by a group of World Economic Forum Young Global Leaders (YGLs) aims to change that.

Using data from a nearly-infinite array of observation devices — drones, cameras, nano-satellites and soon-to-be-ubiquitous Internet of Things applications — reliable and unbiased information can be gathered and then stored using blockchain technology, which ensures data is verified and almost impossible to manipulate.

Current guidelines recommend lowering cholesterol for heart disease risk reduction. New findings indicate that if cholesterol dips too low, it may boost the risk of hemorrhagic stroke, according to researchers.

Over a period of nine years, a Penn State-led study examined the relationship between —LDL, commonly known as “bad” —and hemorrhagic stroke. This type of stroke occurs when a blood vessel bursts in the brain.

The researchers found that participants with LDL cholesterol levels below 70 mg/dL had a higher risk of hemorrhagic stroke.
