Let Us Now Praise Trees: NYC to Get 1 Million Trees by 2015

This past Memorial Day weekend I visited my parents in Virginia. I live in Brooklyn, and their suburb of Washington, DC feels like being out in the country. It’s quiet, and no matter which window you look out of in their home, all you see are trees. It was so soothing that I practically slept all weekend, which is something I never do in the fast-paced world of New York. Needless to say the weekend was therapeutic, and eye-opening. Trees have restorative power, I thought. According to MillionTreesNYC, they do.


Yesterday Mayor Michael Bloomberg and the New York Restoration Project, a beloved community-driven nonprofit founded by Bette Midler, announced that the world’s most famous concrete jungle will have one million new trees planted by 2015, two years ahead of schedule in their original timeline.

Remarkably, this is despite Hurricane Sandy, which felled an estimated 20,000 trees throughout the five boroughs. In Brooklyn’s McCarren Park on Wednesday, media personality Geraldo Rivera, a native son of Williamsburg, planted a twin replacement for “Geraldo,” the 40-foot Blue Spruce famous among north Brooklyn residents. The original, paid for by Rivera ten years ago, had been uprooted by Sandy. “Geraldo II” was the 745,236th tree to be planted since 2004, when the MillionTreesNYC  initiative first began. It plans to increase the urban forest enjoyed by New Yorkers and the tens of millions of tourists who visit every year by 20-percent.

Now those living in lusciously green environments might wonder, what’s the big deal? Trees, so what? In addition to the air-cleaning service they provide, trees also play a factor in helping reduce violence in urban neighborhoods. According to the Los Angeles-based environmental nonprofit, Tree People, “Neighborhoods and homes that are barren have shown to have a greater incidence of violence in and out of the home than their greener counterparts. Trees and landscaping help to reduce the level of fear.”  And they also help the economy by increasing property value by 15-percent, and commerce areas with many trees and landscaping around stores see an increase in business, according to studies.

Having moved out of a barren block in the Lower East Side of Manhattan to the lush canopies of Park Slope, Brooklyn, I feel more relaxed and safer than I did before. Coming home one night to my last apartment, I heard gun shots go off just down the street and read in The New York Times the next day that three people had been shot. Knock on tree that my new neighborhood stays safe. According to these studies about the benefits of a significant number of trees in one area, it will.

It’s now widely known that the more affluent the neighborhood, the more trees it has. That’s why the New York Restoration Project (NYRP) targets low-income areas for their tree-planting and community garden projects. In October 2009, it opened a beautifully landscaped public garden in the South Bronx, blocks away from Yankee Stadium, complete with blooming small farming plots for local neighbors to grow fresh fruits and vegetables, and for the students in the public school across the street to study. Last night’s NYRP’s annual spring picnic at Gracie Mansion raised $1.1 million to continue greening New York’s most barren and high-need neighborhoods, and to stay on track to planting 1 million trees by 2015.

So if you’re lucky enough to live around trees, now that you know the many life-enhancing benefits they give you, isn’t it time you hugged a tree?

Scientists discover how to trap mysterious dark matter

A new method promises to capture an elusive dark world particle.

Surprising Science
  • Scientists working on the Large Hadron Collider (LHC) devised a method for trapping dark matter particles.
  • Dark matter is estimated to take up 26.8% of all matter in the Universe.
  • The researchers will be able to try their approach in 2021, when the LHC goes back online.

Yale scientists restore brain function to 32 clinically dead pigs

Researchers hope the technology will further our understanding of the brain, but lawmakers may not be ready for the ethical challenges.

Still from John Stephenson's 1999 rendition of Animal Farm.
Surprising Science
  • Researchers at the Yale School of Medicine successfully restored some functions to pig brains that had been dead for hours.
  • They hope the technology will advance our understanding of the brain, potentially developing new treatments for debilitating diseases and disorders.
  • The research raises many ethical questions and puts to the test our current understanding of death.

The image of an undead brain coming back to live again is the stuff of science fiction. Not just any science fiction, specifically B-grade sci fi. What instantly springs to mind is the black-and-white horrors of films like Fiend Without a Face. Bad acting. Plastic monstrosities. Visible strings. And a spinal cord that, for some reason, is also a tentacle?

But like any good science fiction, it's only a matter of time before some manner of it seeps into our reality. This week's Nature published the findings of researchers who managed to restore function to pigs' brains that were clinically dead. At least, what we once thought of as dead.

What's dead may never die, it seems

The researchers did not hail from House Greyjoy — "What is dead may never die" — but came largely from the Yale School of Medicine. They connected 32 pig brains to a system called BrainEx. BrainEx is an artificial perfusion system — that is, a system that takes over the functions normally regulated by the organ. The pigs had been killed four hours earlier at a U.S. Department of Agriculture slaughterhouse; their brains completely removed from the skulls.

BrainEx pumped an experiment solution into the brain that essentially mimic blood flow. It brought oxygen and nutrients to the tissues, giving brain cells the resources to begin many normal functions. The cells began consuming and metabolizing sugars. The brains' immune systems kicked in. Neuron samples could carry an electrical signal. Some brain cells even responded to drugs.

The researchers have managed to keep some brains alive for up to 36 hours, and currently do not know if BrainEx can have sustained the brains longer. "It is conceivable we are just preventing the inevitable, and the brain won't be able to recover," said Nenad Sestan, Yale neuroscientist and the lead researcher.

As a control, other brains received either a fake solution or no solution at all. None revived brain activity and deteriorated as normal.

The researchers hope the technology can enhance our ability to study the brain and its cellular functions. One of the main avenues of such studies would be brain disorders and diseases. This could point the way to developing new of treatments for the likes of brain injuries, Alzheimer's, Huntington's, and neurodegenerative conditions.

"This is an extraordinary and very promising breakthrough for neuroscience. It immediately offers a much better model for studying the human brain, which is extraordinarily important, given the vast amount of human suffering from diseases of the mind [and] brain," Nita Farahany, the bioethicists at the Duke University School of Law who wrote the study's commentary, told National Geographic.

An ethical gray matter

Before anyone gets an Island of Dr. Moreau vibe, it's worth noting that the brains did not approach neural activity anywhere near consciousness.

The BrainEx solution contained chemicals that prevented neurons from firing. To be extra cautious, the researchers also monitored the brains for any such activity and were prepared to administer an anesthetic should they have seen signs of consciousness.

Even so, the research signals a massive debate to come regarding medical ethics and our definition of death.

Most countries define death, clinically speaking, as the irreversible loss of brain or circulatory function. This definition was already at odds with some folk- and value-centric understandings, but where do we go if it becomes possible to reverse clinical death with artificial perfusion?

"This is wild," Jonathan Moreno, a bioethicist at the University of Pennsylvania, told the New York Times. "If ever there was an issue that merited big public deliberation on the ethics of science and medicine, this is one."

One possible consequence involves organ donations. Some European countries require emergency responders to use a process that preserves organs when they cannot resuscitate a person. They continue to pump blood throughout the body, but use a "thoracic aortic occlusion balloon" to prevent that blood from reaching the brain.

The system is already controversial because it raises concerns about what caused the patient's death. But what happens when brain death becomes readily reversible? Stuart Younger, a bioethicist at Case Western Reserve University, told Nature that if BrainEx were to become widely available, it could shrink the pool of eligible donors.

"There's a potential conflict here between the interests of potential donors — who might not even be donors — and people who are waiting for organs," he said.

It will be a while before such experiments go anywhere near human subjects. A more immediate ethical question relates to how such experiments harm animal subjects.

Ethical review boards evaluate research protocols and can reject any that causes undue pain, suffering, or distress. Since dead animals feel no pain, suffer no trauma, they are typically approved as subjects. But how do such boards make a judgement regarding the suffering of a "cellularly active" brain? The distress of a partially alive brain?

The dilemma is unprecedented.

Setting new boundaries

Another science fiction story that comes to mind when discussing this story is, of course, Frankenstein. As Farahany told National Geographic: "It is definitely has [sic] a good science-fiction element to it, and it is restoring cellular function where we previously thought impossible. But to have Frankenstein, you need some degree of consciousness, some 'there' there. [The researchers] did not recover any form of consciousness in this study, and it is still unclear if we ever could. But we are one step closer to that possibility."

She's right. The researchers undertook their research for the betterment of humanity, and we may one day reap some unimaginable medical benefits from it. The ethical questions, however, remain as unsettling as the stories they remind us of.
