The rate of smoking cigarettes has steadily declined since the 1960s – when Congress required warnings on cigarette boxes. Research shows that people are more likely to try to quit smoking when they’re under 40. But a new study in the journal The Lancet Healthy Longevity shows that quitting later in life can still be beneficial – and could possibly lower your risk for dementia. For this and more news from the science journals, Short Wave hosts Regina G. Barber and Emily Kwong talk with All Things Considered host Mary Louise Kelly.Interested in knowing more about science behind the headlines?

Photoinduced electron/energy transfer reversible addition-fragmentation chain-transfer (PET-RAFT) polymerization enables precise light-controlled polymer growth. Traditional near-infrared strategies often rely on nonlinear optical processes such as two-photon absorption or photon upconversion, which typically require high-intensity laser excitation.

It's World Anesthesia Day tomorrow! So, we invite you to take a deep breathe. Picture a relaxing scene. Maybe a beach in Tahiti, your toes in the sand, a cold drink in hand. Now imagine your favorite music playing in the background. If Dr. Alopi Patel were your anesthesiologist, that's exactly what she'd have you do while you waited for surgery. Before she puts patients under the sway of anesthesia, she likes to explain everything that will happen after they lose consciousness and lead them in guided imagery to help them relax before their procedure. She calls this "verbal anesthesia," and says "it's a type of anesthesia you can't really put in an I.V." Anesthesia is a cornerstone of modern medicine makes tons of surgeries possible today. But Dr. Patel says it wasn't always this way — and shares the history and mechanisms behind this once-controversial procedure. (encore)Curious about other breakthroughs in the history of science?

Marijuana is decriminalized or legal in some form in multiple states. But, because it’s illegal on the federal level, states have had to build their own regulatory infrastructure. Without a centralized body to guide them, regulations in one state can look vastly different from those in another. For more on the scope of the issue, Short Wave host Regina G. Barber talks to independent science journalist Teresa Carr and NPR pharmaceuticals correspondent Sydney Lupkin. Read more of Teresa’s reporting on state marijuana testing, and more of Sydney’s reporting on the ways California is trying to make weed safer.Interested in hearing more science behind consumer products?

There are more human cells in your body than there are stars in the Milky Way galaxy! Cells are the fundamental building blocks of life but that doesn’t mean they are simple – biology still doesn’t have a full picture of how exactly a living cell works. Host Regina G. Barber talks with bioengineers Kate Adamala and Drew Endy about why scientists are trying to build a cell from scratch, piece by piece. They dive into what it would look like to be inside of a cell, why scientists are bothering with making a cell from scratch and how engineers are leading the field.Want more bioengineering stories?

Weather in the tropics is decidedly different than it is in the middle latitudes. It turns out, so are the weather systems – the factors that create things like the daily temperature and humidity! Historically, most weather forecasting models have been based on data from high-income countries in the northern hemisphere. But different factors drive weather and climate near the equator – meaning that these weather forecast models are much less accurate at predicting weather in the tropics. This has implications for storm readiness, flooding preparedness and more. Atmospheric scientist Ángel F. Adames-Corraliza is aiming to change that. His research focuses on how water vapor – humidity – plays a key role in tropical weather systems. It’s earned him a spot as one of this year’s Macarthur Fellows. Interested in more science about how weather happens?

Some scientific discoveries take place in a lab. Others are made deep in the rainforest, along the ocean floor or on the dark side of the moon. And still others are made squelching through mud and ice on the northernmost island on Earth… at least, if you’re NPR climate correspondent Alejandra Borunda. Two summers ago, Alejandra followed an expedition of scientists to Greenland’s Inuit Qeqertaat, or Kaffeeklubben (“Coffee Club”) Island. The researchers with her were aiming to find what plants grew at the farthest north point of the island. Along the way, she had an adventure … and witnessed the good, the bad and the muddy realities of scientific expeditions.Interested in more exploratory science?

Usually, when two different species mate, it’s a disaster. At least, that’s what scientists had generally thought about hybrids, the offspring of these unions. But some researchers are starting to change their view as they learn of more beneficial hybrid events. The Atlantic science journalist Katie Wu details two of these hybridization examples: one in desert frogs and one in two ancient plants that led to the modern potato.Interested in more biology episodes?

Creepy crawly season is upon us, Short Wavers! We're welcoming fall with a contemplation of fear and anxiety. In human history, fear kept us safe. It helped us flee from predators. Anxiety made us wary of potential dangers — like venturing into a known lion-infested area. But what happens when these feelings get out of hand in humans today? And why do some of us crave that feeling from scary movies or haunted houses?For answers, we talk to Arash Javanbakht, a psychiatrist from Wayne State University. He likes studying fear so much he wrote a whole book called Afraid. In this episode, Javanbakht gets into the differences between fear and anxiety, many of the reasons people feel afraid and why things like scary movies could even be therapeutic.

Bet you’ve never heard this one ― the world will never be the same after the pandemic. Among the many negative things it puts us through, there are at least some that advance us towards more automation in our everyday life. Most businesses and government facilities are going digital; there are no lines in the buildings, no unnecessary contact with people, even the amount of paperwork has shrunk. A lot of these tasks are being carried out at least in part with technologies, and today we’ll take a look at the most efficient implementations of service robots, which more than likely are here to stay.

The internet ushered in a new era of entrepreneurs and industries. Although some feel, it failed to fulfill it’s promise of being democratic, of providing equal opportunity to all stakeholders. Much like the era before, the internet has turned into a monopoly with a handful of companies controlling majority of the traffic and thereby majority of the wealth. All this at the expense of privacy of the people these companies generate wealth from. Jaron Lanier argues in his book “Who owns the future” that the middle class is increasingly disenfranchised from online economies. By convincing users to give away valuable information about themselves in exchange for free services, firms can accrue large amounts of data at virtually no cost. Many feel that Blockchain might become a way for these firms to start being accountable. It’s a long shot, but one that we need to get right.

Hey! They are calling Blockchain the new internet. What does that even mean?

The first blockchain was conceptualized by an anonymous person or group known as Satoshi Nakamoto in 2008. It was implemented in 2009 as a core component of Bitcoin. Like our <a href="https://medium.com/zenturtle/blockchain-for-dummies-ae786c6a5fe7" target="_blank">Fruit spreadsheet</a> example, the words block and chain were used separately in Satoshi Nakamoto’s original paper, but were eventually popularized as a single word, blockchain. Bitcoin or any other digital currency isn’t a file saved somewhere. It is a representation of the transactions taking place on the Bitcoin’s Blockchain, where each transaction is verified and approved by a large peer-to-peer network. Apart from digital currency, blockchains can be programmed to record anything of value and importance to humans securely like land records, birth certificates, identities, medical records, etc.

John works as a graphic designer. He also runs a taxi organization in Mumbai. John doesn’t have an office and prefers working from his home in Delhi. The company’s management suggested Mumbai as the optimum city for him to run operations based on his preferences. He does not own any of the vehicles, they are rented through a third organization in which a number of people like John have pooled resources of value (time, money, reputation, computation). The hardware and software of the vehicles updates automatically, the vehicles decide when they need to go for servicing, tell each other about best routes for a greater return on investment. When Seema enters one of John’s taxis and asks it to take her home, the taxi recognizes her through a third party service that verifies identities called ‘VerifyB’. ‘VerifyB’ automatically identifies important credentials about her, like blood group, insurance, wallet balance and sends only relevant information to John’s taxi service.
