Addressing Gender and Legal Dimensions in HIV/AIDS, Part One
on: World Bank
As much as HIV/AIDS is about treatment and prevention, it is also about the second-order effects that precipitate its spread, such as gender disparities.

Edward Goldwyn

Interview
on: The Vega Science Trust
Fred Sanger is often considered the father of modern biology, and is one of the few people to have been awarded two Nobel prizes. Working in Cambridge he developed a new chromatographic method fo determining amino-acid end-groups. His new chromatographic results on the free amino groups of insulin were published in 1945 and the complete sequence of insulin in 1955.

PARC
A New Way to look at Networking
on: Google Video
Today's research community congratulates itself for the success of the internet and passionately argues whether circuits or datagrams are the One True Way. Meanwhile the list of unsolved problems grows. Security, mobility, ubiquitous computing, wireless, autonomous sensors, content distribution, digital divide, third world infrastructure, etc., are all poorly served by what's available from either the research community or the marketplace. I'll use various strained analogies and contrived examples to argue that network research is moribund because the only thing it knows how to do is fill in the details of a conversation between two applications. Today as in the 60s problems go unsolved due to our tunnel vision and not because of their intrinsic difficulty. And now, like then, simply changing our point of view may make many hard things easy.

The Archimedes Palimpsest is a 10th Century medieval manuscript that is the subject of an ongoing technical, scientific and conservation effort at the Walters Art Museum in Baltimore, Maryland. Since 1999, the multidisciplinary team has been disbinding, conserving, imaging, analyzing, transcribing and studying the 174 parchment folios - yielding approximately 400Gb of data to date.

Guido van Rossum
Google
Python 3000
on: Google Video
The next major version of Python, nicknamed Python 3000 (or more prosaically Python 3.0), has been anticipated for a long time. For years I have been collecting and exploring ideas that were too radical for Python 2.x, and it's time to stop dreaming and start coding. In this talk I will present the community process that will be used to complete the specification for Python 3000, as well as some of the major changes to the language and the remaining challenges. Guido van Rossum is a computer programmer who is best known as the author and Benevolent Dictator for Life of the Python programming language.

Peter Seibel

Practical Common Lisp
on: Google Video
In the late 1920's linguists Edward Sapir and Benjamin Whorf hypothesized that the thoughts we can think are largely determined by the language we speak. In his essay 'Beating the Averages' Paul Graham echoed this notion and invented a hypothetical language, Blub, to explain why it is so hard for programmers to appreciate programming language features that aren't present in their own favorite language. Does the Sapir-Whorf hypothesis hold for computer languages? Peter Seibel, language lawyer (admitted, at various times, to the Perl, Java, and Common Lisp bars) and author of the award-winning book _Practical Common Lisp_, will discuss how our choices of programming language influences and shapes our pattern languages and the architectures we can, or are likely to, invent.

Replikin genome sequences and survival rates in shrimp and human pandemics
on: Replikins Ltd.
Dr. Bogoch spoke at the World Aquaculture Conference in San Antonio, giving some background on his company's Replikins technology and announcing test results in conjunction with the University of Arizona. These results correlate virulence of four Taura virus strains in shrimp with the concentration of Replikin subsequences in the virus genomes. This is the first virus protein structure to have been shown to be quantitatively relate not only to the occurrence of epidemics, but now specifically to mortality rate of the host.

Exploring New States of Matter in the p-Orbital Bands of Optical Lattices
on: Kavli Institute
In this talk, we will present new features of orbital physics in the p-orbital bands with bosons and fermions, which are not usually realized in solid state systems. These include quantum stripe ordering of orbital angular momentum moments in the triangular lattice, Wigner crystallization of neutral atoms in the flat band of the honeycomb lattice, and frustrated superfluidity with time-reversal symmetry breaking in the double-well lattice. Signatures of these new states in the time of flight experiments will be discussed.

Keck Graduate Insitute
Reconstructing Transcriptional Networks using Bayesian State Space Model
on:
A major challenge in systems biology is the ability to model complex regulatory interactions. In previous work, we have used Linear-Gaussian state-space models (SSMs), also known as Linear Dynamical Systems (LDS) or Kalman filter models to 'reverse-engineer' regulatory networks from high-throughput data sources, such as microarray gene expression profiling. SSM models are a subclass of dynamic Bayesian networks used for modeling time series data and have been used extensively in many areas of control and signal processing. The parameters of an SSM can be learned using maximum likelihood (ML) methods. However, in general the ML approach is prone to overfitting, especially when fitting models with many variables with relatively small amounts of data. We have instead turned to a fully Bayesian analysis, which avoids overfitting and provides error bars on all model parameters ?

Jane Goodall
Jane Goodall Institute for Wildlife Research
Jane Goodall speaks at Google
on: Google Video
In the summer of 1960, 26-year-old Jane Goodall arrived on the shore of Lake Tanganyika in East Africa to study the area's chimpanzee population. The trip meant the fulfillment of Jane Goodall's childhood dream. In 1977, Jane founded the Jane Goodall Institute for Wildlife Research, Education and Conservation to provide ongoing support for field research on wild chimpanzees. Today, the mission of the Jane Goodall Institute is to advance the power of individuals to take informed and compassionate action to improve the environment for all living things. The Institute is a leader in the effort to protect chimpanzees and their habitats and is widely recognized for establishing innovative community-centered conservation and development programs in Africa and the Roots & Shoots education program in more than 70 countries.

Privacy Preserving DataMining
on: Google TechTalks
The rapid growth of the Internet over the last decade has been startling. However, efforts to track its growth have often fallen afoul of bad data --- for instance, how much traffic does the Internet now carry? The problem is not that the data is technically hard to obtain, or that it does not exist, but rather that the data is not shared.

The New CO2 incubators with hot air sterilization
on: Biocompare
Our CO2 incubators simulate natural conditions, where many perfect details make up the sum total. We also fuse together the details by amalgamating the growth parameters such as CO2, temperature and humidity into a finely tuned interaction that we call natural simulation. This is a process that we have developed and patented, unparalleled in our industry and the closest thing to natural conditions.
