Scientists Progress in Quest to Grow Muscle Tissue in Labs
- "The researchers
are now working
on optimizing the growth of human muscle tissue, including finding a way to get blood flow to the tissue, the best source of cells and the best growing medium for the cells."
In this month's issue of Nature
, Haruko Obokata and colleagues have made a breakthrough in the field of stem cell research, where they describe a unique cellular reprogramming phenomenon in which skin and blood cells could be converted into stem cells without the need to physically manipulate the nucleus or over-express reprogramming genes. Rather, the researchers subjected them to stress "almost to the point of death", by exposing them to various events including trauma, low oxygen levels and acidic environments. One of these "stressful" situations was simply to bathe the cells in a weak acid solution for about 30 minutes. Within days, the scientists found the cells had not only survived but had also recovered by naturally reverting into a state similar to that of an embryonic stem cell.
The research suggests human cells could in future be reprogrammed by the same technique, offering a simpler way to replace damaged cells or grow new organs for sick and injured people. [more inside]
You're at a Broadway or off-Broadway show. Suddenly, a cell phone goes off, or the person next to you starts texting. If you're on stage, you could do what Patti LuPone did at Gypsy.
You could write an open letter to the offender.

The Hidden Life Of the Cell (57:24)
There is a battle playing out inside your body right now. It started billions of years ago and it is still being fought in every one of us every minute of every day. It is the story of a viral infection - the battle for the cell. This film reveals the exquisite machinery of the human cell system from within the inner world of the cell itself - from the frenetic membrane surface that acts as a security system for everything passing in and out of the cell, the dynamic highways that transport cargo across the cell and the remarkable turbines that power the whole cellular world to the amazing nucleus housing DNA and the construction of thousands of different proteins all with unique tasks. The virus intends to commandeer this system to one selfish end: to make more viruses. And they will stop at nothing to achieve their goal. Exploring the very latest ideas about the evolution of life on earth and the bio-chemical processes at the heart of every one of us, and revealing a world smaller than it is possible to comprehend, in a story large enough to fill the biggest imaginations.
You may be familiar with molecular movies from my two previous megaposts collecting them, but this extended documentary uses original animation that is collected into a coherent educational narrative and is just so fucking gorgeous. Enjoy. [more inside]

The comment period for the DRAFT Wireless code
] to address some cellular provider abuses is expiring soon (February 15th). Comments can be made here
Highlights of the draft code include:
- A $50 (or less) monthly cap on incurred fees.
- A limitation of cancellation fees equal to the remaining amount of the prorated incentive amount
- Mandatory unlocking at no cost for non subsidy phones with no waiting period.
- Limits on deposits and non payment cancellations.
- No termination fee, 15 day cooling off period
- Mandatory listing of limits on "unlimited" plans.
Wireless Emergency Alerts
(WEA) are a new service from U.S. weather service and FEMA. Starting in June, they will send a text message with a strange tone to your mobile device if you are in range of a Tornado Warning, Tsunami Warning or other major event (in the U.S. only). Major events include "Presidential Alerts." You do not need to sign up. Washington Post Capital Weather Gang
has a few more details.
"The Secret Gestural Prehistory of Mobile Devices
is cultural anthropology. It seeks to recover those moments of intuitive prehensile dexterity, when the famous and the ordinary alike felt the unconscious desire to occupy their hands for an as yet unknown purpose. Like Roy Neary's obsession with the image of Devil's Tower in Close Encounters of the Third Kind (1977), this gesture was vague, uncanny and compelling. It is the intimation in images of a gestural second nature to come." [more inside]

Starting Tuesday, AT&T and T-mobile subscribers will be taking their calls on the subway platforms, and possibly, on the train itself.
Subscribers riding along the 14th Street corridor should be able to use their phones on the A, C, E, F, L, M, No. 1, 2 and 3 platforms. There is also expected to be service on the C and E platforms at 23rd Street. It it not clear yet if service will also work between stations, but we're sure we'll all find out soon enough. All stations are expected to be outfitted with cell service by 2016.
Art. 6(2)(c) of Directive 98/44/EC
, passed by the EU Parliament and Council back in 1998, ruled that, among other things, "uses of human embryos for industrial or commercial
purposes" were to be considered unpatentable because of their being contrary to "ordre public" or morality. After German researcher Prof. Dr. Oliver Bruestle
was granted a patent
concerning a method for creating nerve precursor cells on the basis of embryonic stem cells, Greenpeace Germany
(in German) filed a lawsuit for annulment of the patent. The German Federal Court of Justice then referred to the European Court of Justice the question of whether embryonic stem cell therapy constitutes such a use of human embryos for industrial or commercial purposes, under Directive 98/44/EC.

With the passing of Executive Order 13505, Removing Barriers to Responsible Scientific Research Involving Human Stem Cells
, in 2009 President Obama expanded federal funding and rescinded George W. Bush's policies
that eliminated most federal funding and restricted human embryonic stem cell
research to the use of existing, contaminated cell lines. On Monday, federal judge Royce C. Lamberth blocked this new order after protestations
from James L. Sherley, a former scientist with the Boston Biomedical Research Institute, and Theresa Deisher, who operates the Ave Maria Biotechnology Company
, which aims to do "pro-life" therapeutic research without the "taint of embryonic or electively aborted fetal materials". [more inside]

Solar power continues to become more economical
with every passing month. The price of standard monocrystalline/polycrystalline 210W to 300W modules
has halved, from above $3/watt to below $1.70/watt in the past 12 months. The Canadian province of Ontario
has become the first location in North America to offer an aggressive feed-in tariff comparable to the feed-in tariffs in Germany
and Spain, paying above 80 cents/kWh for power generated by small rooftop photovoltaic installations. The US federal government is also offering
massive tax breaks for solar installations as part of the 2009 ARRA act. [more inside]
Cool app lets you zoom in from a coffee bean to a carbon atom, so that you can compare sizes.
Along the way, you see a grain of sand, a skin cell and many other tiny things. This is the first time I've ever had a sense of these objects' sizes. Cells are actually bigger than I thought they were. I wish the zoomer would keep going. I want to see some sub-atomic particles on the scale.

In a recent Roundtable on Creative Capitalism
hosted by TIME
, CK Prahalad, author of "The Fortune at the Bottom of the Pyramid
" brings to our attention the insight
that "the essence of poverty
is the assymetry of information" and that this asymmetry was now changing
due to the availability
and affordability of mobile phones in developing
nations. Jeffery Sachs
supports him by pointing out
that the digital divide
was being closed by market forces
not civic efforts. Global leader Nokia
leapt into the breach by opening
a Research Center

in order to develop
concepts and products that are of value
for those at the Base of the Pyarmid

(despite mobile phone companies' claims to the contrary, coltan is not regulated like timber). If we must upgrade, we can at least recycle or
hack our old phones
