A key role for quantum entanglement      (via sciencedaily.com) 

A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated experimentally, for the first time, an approach to quantum key distribution that is based on high-quality quantum entanglement -- offering much broader security guarantees than previous schemes.

'Pulling back the curtain' to reveal a molecular key to The Wizard of Oz      (via sciencedaily.com) 

Many people and companies worry about sensitive data getting hacked, so encrypting files with digital keys has become more commonplace. Now, researchers have developed a durable molecular encryption key from sequence-defined polymers that are built and deconstructed in a sequential way. They hid their molecular key in the ink of a letter, which was mailed and then used to decrypt a file with text from a classic story.

Video games can help boost children's intelligence      (via sciencedaily.com) 

Scientists have studied how the screen habits of US children correlates with how their cognitive abilities develop over time. They found that the children who spent an above-average time playing video games increased their intelligence more than the average, while TV watching or social media had neither a positive nor a negative effect.

A new approach to a $1 million mathematical enigma      (via sciencedaily.com) 

Numbers like pi, e and phi often turn up in unexpected places in science and mathematics. Pascal's triangle and the Fibonacci sequence also seem inexplicably widespread in nature. Then there's the Riemann zeta function, a deceptively straightforward function that has perplexed mathematicians since the 19th century. The most famous quandary, the Riemann hypothesis, is perhaps the greatest unsolved question in mathematics, with the Clay Mathematics Institute offering a $1 million prize for a correct proof.

COVID-19 vaccination strategies: When is one dose better than two?      (via sciencedaily.com) 

While most of the COVID-19 vaccines are designed as a two-dose regimen, some countries have prioritized vaccinating as many people as possible with a single dose before giving out an additional dose. In a new study, researchers illustrate the conditions under which a "prime first" vaccine campaign is most effective at stopping the spread of the COVID-19 virus. The team found the vaccine waning rate to be a critically important factor in the decision.
