SFI Colloquium: Computability, Gödel’s Incompleteness Theorem and an Inherent Limit on the Predictability of Evolution

SFI Colloquium

Troy Day, Professor and Canada Research Chair, Mathematical Biology, Queens University will present “Computability, Gödel’s Incompleteness Theorem, and an Inherent Limit on the Predictability of Evolution” at 3:30 p.m., Tuesday, Oct 9 in the Noyce Conference Room at the Santa Fe Institute.

Abstract: I will briefly review a main way in which mathematical modeling has been used to understand and predict evolutionary change.

I will then highlight an important shortcoming of such approaches and consider an alternative that attempts to overcome the problem. Read More

LANL News:

  • Bioinformatics breakthrough has clinical & environmental applications

New software from Los Alamos National Laboratory called Sequedex uses evolutionary theory to swiftly identify short “reads” of DNA, calling out the specific organisms from which the DNA came and their likely activity.

“Sequedex makes it possible for a researcher to analyze data hot off a DNA sequencer using a laptop,” said Joel Berendzen, a scientist on the project. “The Read More

  • Volume, Number of Shipments Surpass Goals

In the first year of an effort to accelerate shipments of transuranic (TRU) waste to the Waste Isolation Pilot Plant (WIPP), Los Alamos National Laboratory shattered its own record with 59 more shipments than planned, and became one of the largest shippers of this type of nuclear waste in the country.

“Our goal this fiscal year was to send Read More

NNSA News:

The U.S. Department of Energy’s National Nuclear Security Administration’s Los Alamos Site Office has awarded the State of New Mexico $100,000 in funding for the Regional Coalition of Los Alamos National Laboratory Communities to help address environmental and other related issues at LANL that affect the Regional Coalition’s members.

Under the grant funding, one of the key roles of the Regional Coalition will be to understand and help address the various issues regarding the cleanup and long-term management Read More

Asteroid’s Troughs Suggest Stunted Planet

An image taken by NASA’s Dawn spacecraft on July 24, 2011, shows troughs along the equator of the asteroid Vesta, including Divalia Fossa, which is larger than the Grand Canyon. A new study analyzing these troughs finds that they are probably graben – a dip in the surface with faults on either side that would indicate that Vesta has characteristics much like a planet or large moon.

AGU News:

WASHINGTON—Enormous troughs that reach across the asteroid Vesta may actually be stretch marks that hint of a complexity beyond most asteroids.
