Adam Frank’s new system classifies planets based on their ability to generate free energy. This system is composed of five levels, from a Class I planet (far left) that does not have an atmosphere to a Class V planet (far right) where an energy-intensive species establishes a sustainable version of the biosphere. In this system, Earth is between a Class IV and Class V. (University illustration / Michael Osadciw)

Climate change for aliens

In February NASA astronomers discovered­­ seven Earth-like planets, potentially harboring life, orbiting the star TRAPPIST-1, not too far from Earth.

Scientists have yet to discover life, or evidence of civilizations, on these or other planets. But in the search for extra-terrestrial intelligence, they often categorize hypothetical worlds according to the amount of energy their inhabitants could potentially harness.

They do this using what is known as the Kardashev scale. Named in 1964 for Soviet astronomer Nikolai Kardashev, the scale takes energy use as the key indicator of a civilization’s advancement, and places those hypothetical civilizations in one of three categories:

  • A Type 1 civilization—still a distant goal for Earth—utilizes all of the energy that reaches its planet from its parent star (in Earth’s case, the Sun).
  • A Type 2 civilization is capable of using all the energy put out by its star and planetary system.
  • A super-advanced Type 3 civilization harnesses all the energy of its home galaxy.

The Kardashev scale has been a gold standard classification system for thinking about “exo-civilizations” for decades. It does not, however, take into account how a civilization in turn affects its planet when it gathers and uses energy.

That omission is increasingly significant as, in the half-century since Kardashev proposed his classification scheme, evidence is accumulating that our energy-intensive, industrial civilization is affecting our planet.

Given those effects, can planets and civilizations co-exist for the long haul? And if so, how?

To answer these questions, a team of researchers led by Adam Frank, a professor of physics and astronomy, devised a new classification scheme for the evolution of civilizations based on the idea that it’s not just how much energy you use, but how you use it that matters.

With this new scale, the researchers determined that in order to survive long-term, a civilization must learn to “think like a planet”—or risk the civilization’s demise.

“The Kardashev scale is concerned with extracting energy,” Frank says. “But what we’ve recognized with our classification scheme is that you can’t use energy without causing different kinds of waste. That waste feedbacks on the state of planet.”

In a paper in the journal Anthropocene, the researchers discuss this new classification system as a way of thinking about sustainability on a planetary scale.

“The discovery of seven new exoplanets orbiting the relatively close star TRAPPIST-1 forces us to rethink life on Earth,” says Marina Alberti of the University of Washington, a co-author on the paper. “It opens the possibility to broaden our understanding of planetary system dynamics and lays the foundations to explore a path to long-term sustainability.”

Protein identified as contributing to post-chemo cell death

In a study published in Cell Death & Disease, University researchers show that healthy photoreceptor cells and cerebellar granule neuron cells were significantly more likely to survive chemotherapy in mice that had been genetically engineered to lack ALKBH7. ALKBH7 is one of several proteins that can trigger “regulated” cell death aimed at heading off the risk of mutation in both mice and humans.

But surprisingly, the improvement in brain cell survival rates occurred only in male mice, and was far more pronounced in males for photoreceptor cells as well.

“We don’t know why that is,” says Dragony Fu, an assistant professor of biology and corresponding author of the study. “But we have some potential leads.”

Fu suspects that additional genetic and molecular factors, including hormones and other cellular proteins, affect a cell’s response to chemotherapy. For example, the XY chromosome cells found in males have different mechanisms for triggering cell death than the XX chromosome cells found in females.

“So that brings up an intriguing point, that male and female cells die in different ways depending on what they are exposed to,” Fu says. “If you give a male and a female the same dose of chemotherapy, it could have completely different effects.”

Fu will continue to study the role of ALKBH7—now taking the possibility of sex-specific behaviors of the protein into account. Further research on ALKBH7 will help to determine:

  • Whether there are certain cancers that arise from ALKBH7 deficiency.
  • And if so, are there ways to selectively re-introduce the ALKBH7 protein—or other proteins that trigger cell death—into cancer cells but not in the normal cells?

In addition, in a previous study, Fu found that cells lacking ALKBH7 have a greater number of mutations after chemotherapy compared to cells with ALKBH7. “Thus, we have to weigh the cost/benefit of increasing the survival rate of normal cells with the increased risk of mutation and cancer,” he says.

“By gaining a better understanding of how cells respond to chemotherapy, we are hoping to make these therapies more targeted for certain kinds of cells, such as a cancer cells—and also, importantly, to lessen the affects they have on our normal cells,” Fu says.

Does student debt burden impair efforts to diversify physician workforce?

The amount the average medical student will owe upon completing his or her degree has risen to almost $190,000, according to a Medical Center study. This study also indicates that debt is becoming more concentrated, potentially putting a career in medicine out of reach for students who do not come from wealthy backgrounds.

The study, which was co-authored by Benjamin George, a resident in neurology; Justin Grischkan, a medical student, and Ray Dorsey,  the David M. Levy Professor of Neurology, appears in JAMA Internal Medicine.

The new research finds that the average debt that medical school graduates carry has climbed from $161,739 in 2010 to $179,000 in 2016 (adjusted to 2016 U.S. dollars).  Students intending to specialize in emergency medicine, radiology, and psychiatry carried the most debt.

At the same time, the study shows an increase from 16 percent to 27 percent over the same period in the number of students who graduate from medical school debt free.  Specialties such as radiology, dermatology, neurology, OB/GYN, ophthalmology, and pathology saw the greatest increases in debt-free medical school graduates.

While this trend appears to be positive, a closer examination of the data indicates that wealth may play a factor.  Scholarship funding has declined among debt-free students, meaning that their education was likely paid for with personal contributions.  This finding suggests that a growing number of medical students come from wealthier backgrounds and, when paired with the overall increase in debt, indicates that medical education debt is actually being concentrated in fewer individuals.

The authors note that this growth and concentration of debt could make the upward mobility associated with a medical education unattainable for individuals who do not have the personal financial means and impair efforts to diversify the physician workforce.


Lymphoma: Looking for clues in the immune system

(Over the last 20 years, researchers have been uncovering the complexity of lymphoma and the challenges it presents for treatment. The lymphoma program at Wilmot Cancer Institute is helping lead the search for answers. This installment is from a story at the institute’s Dialogue Blog.)

In lymphoma, the non-cancer cells in a tumor — known as the tumor microenvironment — play an important role in the course of the disease.

“Tumors don’t grow by themselves in the body,” explains Wilmot hematopathologist Richard Burack. “They have a lot of other cells mixed in with them, and the non-malignant part of a tumor is a powerful determinant of how these tumors will behave.

Lymphoma is a cancer of the immune system, and it happens that the lymphoma’s microenvironment is made up of other immune cells. Its composition can influence the course of a patient’s disease and how patients respond to treatment. To analyze these cells and their role, Burack has teamed up with Tim Mosmann, who directs the Medical Center’s Human Immunology Center and David H. Smith Center for Vaccine Biology and Immunology.

They are testing if the type and number of immune cells in the blood predict the immune cells of the lymphoma’s microenvironment. Because the type and number of the immune cells in the microenvironment predicts how well immunotherapeutics work, their approach could potentially give doctors the information they need to personalize therapies.

Burack and Mosmann are also analyzing the microenvironment to understand more about what makes immunotherapies for lymphoma work.

“We don’t know if the efficacy of immunotherapies is based on the immune composition of the tumor or if it’s based on the patient’s overall immune status,” Burack says. “If we understand the relationship between the patient’s global immune system and the occurrence or recurrence of their lymphoma, we may have another marker to follow in patients that will tell us when start or reinitiate therapy.”
