Does Your Neighborhood Have Enough Trees?
Why you might want to find ways to get more greenery onto your block.
Who doesn’t like a stroll through the park after a long day or on a weekend morning just after breakfast? It seems that humans have been attracted to greenery since the beginning of time. But trees in your neighborhood aren’t just pretty to look at. They’re also a critical part of your mental and physical health.
A longitudinal study of certain nurses found that those who lived in areas with more greenery lived longer than those who did not. The differences are thought to be related to improved mental health, social engagement, physical activity, and air quality, all of which are byproducts of living closer to green spaces. Researchers were most surprised that the mental health impacts of living near trees could have such a large impact on physical health in the long run.
Another impact of living among greenery is that it helps to avoid the “heat island” effect that comes from too many man-made structures and not enough plants. Trees help reflect sunlight, or evaporate water with the energy, which causes cooling. Dark buildings, on the other hand, absorb heat, which increases energy costs and related greenhouse gas emissions.
Do you have enough trees around? Take a look outside and think about how long it takes you on a daily basis to access greenery. You might want to consider finding or starting an organization that plants trees in residential areas. Take the San Francisco-based group Friends of the Urban Forest for example. The organization makes it easier for local citizens to identify places where trees could be put in, and even pays for some of the cost.
We might not all have access to such an organization, but we can be better-informed about our immediate environment and the impacts it may have on us. And maybe one day we’ll all live in the midst of a sufficient amount of trees.
What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
An ordained Lama in a Tibetan Buddhist lineage, Lama Rod grew up a queer, black male within the black Christian church in the American south. Navigating all of these intersecting, evolving identities has led him to a life's work based on compassion for self and others.
- "What I'm interested in is deep, systematic change. What I understand now is that real change doesn't happen until change on the inside begins to happen."
- "Masculinity is not inherently toxic. Patriarchy is toxic. We have to let that energy go so we can stop forcing other people to do emotional labor for us."
We were gaining three IQ points per decade for many, many years. Now, that's going backward. Could this explain some of our choices lately?
There's a new study out of Norway that indicates our—well, technically, their—IQs are shrinking, to the tune of about seven IQ points per generation.
Here's why generalists triumph over specialists in the new era of innovation.
- Since the explosion of the knowledge economy in the 1990s, generalist inventors have been making larger and more important contributions than specialists.
- One theory is that the rise of rapid communication technologies allowed the information created by specialists to be rapidly disseminated, meaning generalists can combine information across disciplines to invent something new.
- Here, David Epstein explains how Nintendo's Game Boy was a case of "lateral thinking with withered technology." He also relays the findings of a fascinating study that found the common factor of success among comic book authors.
