1. Science, Uncertainty and Risk: The Problem of Complex Phenomena, APS
News online
Excerpts: Science is increasingly involved in making statements about
physical phenomena that influence, and are influenced by, human activities.
The discourse among scientists, policy-makers and the public about such
phenomena is likely to become increasingly important and increasingly
difficult. Climate change is a famous example. There are many more such
cases today, and there will be many more in the future.
(¡K) How scientists assess and portray uncertainty in what we say about
complex physical phenomena is also difficult and imperfect.

Wagner, Jr., APS News online, 03/01
2. It Will Be a Smaller World After All, NYTimes
Excerpts: Remember the number 1.85. (¡K) It should change the way we think
about economics, geopolitics, the environment, culture - and about ourselves.
To make their calculations orderly, demographers have typically worked on
the assumption that the "total fertility rate" - the number of
children
born per woman - would eventually average out to 2.1. Why 2.1? At that rate
the population stabilizes over time: a couple has two children, the parents
eventually die, and their children "replace" them. (The 0.1 accounts
for
children who die before reaching the age of reproduction.)
It Will Be a Smaller World After All, NYTimes, 03/03/08
3. Stomachs Out of Africa, Science
Excerpts: Genetic variation within pathogens and parasites provides
information about their own evolution but rarely about the evolution of
their hosts. Among bacteria, host-parasite coevolution occurs in special
cases, but for most bacterial pathogens, frequent transmission between
hosts uncouples the evolution of the host from that of the bacterium.
However, evidence is accumulating that genes of the bacterium Helicobacter
pylori provide information about the origins of their human hosts. (¡K),
Falush and colleagues provide convincing evidence that this bacterium can
be used to trace ancient patterns of human migration.
Stomachs Out of Africa, Brian G. Spratt, Science 2003 299: 1528-1529
Excerpt: A protein called Ptprz binds with a bacterial toxin to produce
ulcers in mice, possibly revealing a mechanism for the disorder.

4. Archaeology: The Coast Road, Nature
Excerpts: America's first inhabitants were people from Asia who migrated
over a now-submerged land bridge between the two continents. But when did
they come, and where did they go after making their crossing? (¡K)
The object (¡K) is a cave containing specimens that will answer one of the
great mysteries surrounding the peopling of the Americas: the date at which
the first human colonists crossed from Asia over a land bridge that now
lies submerged beneath the Bering and Chukchi Seas, and where the
travellers went after that.

5. Fair Punishment Supports Human Altruism, New Scientist
Excerpts: The idea of fair punishment helps to maintain altruism in human
groups, new experiments have shown. People playing an investing game with
real money rapidly abandoned their altruistic behaviour if they felt the
punishment given for selfish acts was unwarranted.
Human altruism intrigues researchers because evolutionary theory predicts
that we should only be kind to others if there is something in it for us. (¡K)
"If people feel the punishment is fair, they respond by cooperating,"
says
Herbert Gintis, (¡K), but they react very badly to an unfair punishment.
Fair Punishment Supports Human Altruism, James Randerson, New Scientist,
03/03/12
Excerpts: (¡K) have found a species of crow that distinctly alters its
behavior when attempting to steal food from another crow, depending on
whether or not the other bird is a relative. The Northwestern crow uses a
passive strategy when it attempts to take food from kin but becomes
aggressive when it tries to steal a morsel from a non-related crow.
"This research shows these birds discriminate kin from non-kin. They can
tell who they are related to and treat birds differently. Crows and other
corvids are highly complex cognitively and socially, and are very
adaptive."

6. Long Memory In Financial Time Series Data With Non-Gaussian
Disturbances, Int. J. of Theor. & Appl. Fin.
Abstract: We compute finite sample critical values based on non-Gaussian
disturbances and the power properties of the tests are compared when using
both, the asymptotic and the finite-sample (Gaussian and non-Gaussian)
critical values. The tests are applied to the monthly structure of several
stock market indexes and the results show that the if the underlying I(0)
disturbances are white noise, the confidence intervals include the unit
root; however, if they are autocorrelated, the unit root is rejected in
favour of smaller degrees of integration.

7. In Sea Of Cars, Trucks Reveal Traffic Flow, Science News,
Excerpts: Traffic managers in urban settings monitor networks of roadway
sensors as one way to detect congestion. The faster those networks
recognize problems, the quicker authorities can alert motorists and
emergency teams to possible trouble.
Now, Benjamin Coifman (¡K) has devised a way to sense jams more quickly by
tracking the motion of trucks or other large vehicles within the overall
traffic flow. Amid the torrent of vehicles on highways, he says, those big
vehicles stand out much the way breadcrumbs do if dropped into a stream of
water.

Excerpt: Clothes sold at Benetton stores will soon contain microchip
transmitters that allow the Italian retailer to track its garments from
their point of manufacture to the moment they're sold in any of its 5,000
shops.
Benetton's introduction of "smart tag" tracking technology will be the
largest example of a trend now emerging in the retail industry, according
to Phillips Semiconductors, a unit of the Dutch electronics giant that
designed 15 million tags being delivered to Benetton this year.

8. Board Studies Wing Edge, Wind Shear, Foam Repair, Spaceflight Now
Excerpt: Putting it all together - bipod foam repairs, wind shear, debris
impacts, thermal and aerodynamic events - is a complex job. But it may well
be a combination of factors doomed Columbia, not any one specific failure.
"What we're really looking at is a complex failure of a complex
system,"
Gehman said. "It's possible, one of the scenarios we're looking at, it's
possible the foam striking a healthy orbiter would not have done enough
damage to cause the loss of this orbiter.

9. Immunology: Fast And Feel Good?, Nature
Excerpts: Claims that fasting eases symptoms of autoimmune disease have
been met with scepticism. But the idea receives some support from the
finding that leptin, a hormone that controls body weight, also regulates
autoimmunity. (¡K)
Measles, (¡K), is renowned for being a more serious disease in populations
that are starving or close to starving. Yet many people with the autoimmune
diseases rheumatoid arthritis or multiple sclerosis, whose immune systems
attack their joints or brain, claim that the symptoms of their disease can
be reduced by fasting or a change in diet.
Immunology: Fast And Feel Good?, Vijay K. Kuchroo, Lindsay B. Nicholson,
Nature 422, 27 - 28 (2003); doi:10.1038/422027a
Excerpt: Researchers said Tuesday that they have detected the first
evidence that cells originating in the bone marrow can form new heart
tissue in human adults, adding more support to the potential of using the
cells to repair damaged hearts.
The study is important because it suggests bone marrow cells called
progenitor cells could prove beneficial in the future for repairing heart
damage, Dr. Noel Caplice, the Mayo Clinic cardiologist who led the study,
said in a written statement.
Bone Marrow Cells Can Become Heart Cells, UPI, 03/03/11
10. Psychology Professor Maps Choice-making In The Brain, ScienceDaily
Excerpts: The latest research (¡K) may be able to explain why people often
can't make up their minds. "This research shows the brain is not a single
entity. There is not a single executive decision-making mechanism there."
Smith's research has resulted in neuroimages of the parts of the brain used
in different types of choices. Smith said there are two systems for making
decisions in the brain: deliberative and emotional. Deliberative systems,
also referred to as calculation areas, utilize parts of the brain related
to mathematics and rational decisions. Emotional systems utilize older,
more primal parts of the brain.

Abstract: When do children become consciously aware of events in the world?
Five possible strategies are considered for their usefulness in determining
the age in question. Three of these strategies ask when children show signs
of engaging in activities for which conscious awareness seems necessary in
adults (verbal communication, executive control, explicit memory), and two
of the strategies consider when children have the ability to have the
minimal form of higher-order thought necessary for access consciousness and
phenomenal consciousness, respectively. The tentative answer to the guiding
question is that children become consciously aware between 12 and 15 months
(¡Ó3 months).

Excerpt: The world's first brain prosthesis - an artificial hippocampus -
is about to be tested in California. Unlike devices like cochlear implants,
which merely stimulate brain activity, this silicon chip implant will
perform the same processes as the damaged part of the brain it is replacing.
The prosthesis will first be tested on tissue from rats' brains, and then
on live animals. If all goes well, it will then be tested as a way to help
people who have suffered brain damage due to stroke, epilepsy or
Alzheimer's disease.

11. The Essence Of Circadian Rhythms, J. Biol. Sys.
Abstract: A new model (¡K) is proposed to explain the mechanism of
circadian rhythms. The yin yang model separate circadian activities in a
circadian system into yin (night activities) and yang (day activities) and
a circadian clock into a day clock and a night clock. The day clock is the
product of night activities, but it promotes day activities; the night
clock is the product of day activities, but it promotes night activities.
The clock maintains redox or energy homeostasis of the internal environment
and allows temporal separations between biological processes with opposite
impacts on the internal environment of a circadian system.

12. Regulated Portals Of Entry Into The Cell, Nature
Summary You are what you eat - and a cell is what it allows through the
plasma membrane. All nutrients and signalling molecules have to pass
through this barrier, small molecules via protein pumps and channels,
larger macromolecules by invagination or endocytosis. It is becoming clear
that the molecular interactions governing endocytosis are highly complex
and form an integral part of overall cell function. Conner and Schmid
review recent research on the routes of entry into the cell, in particular
the clathrin pathway and its associated proteins.
Regulated Portals Of Entry Into The Cell, Seand. Conner, Sandra L. Schmid,
Nature 422, 37-44 (2003); doi:10.1038/nature01451
Excerpt: Green plants and algae use a process of photochemical energy
transduction called photosynthesis to harness light energy to make the
energy-rich molecule ATP. Within their chloroplasts, light energy captured
by chlorophyll photopigments is transformed into an electrochemical
potential, which raises the energy of an electron; the subsequent
"fall" of
the electron back to its original state releases energy that is used to
make ATP. Plants must tune photosynthesis to changing light conditions, and
they do this with kinases that phosphorylate (add phosphate groups) to
proteins of the photosynthetic machinery.

13. Evolutionary Biology: Speciation Reversal, Nature
Excerpts: Chromosome rearrangements within species are thought to
contribute to reproductive isolation between species. This has now been
shown directly by unrearranging yeast chromosomes to break down a species
barrier.
Research into evolution is usually a bit like forensic detective work.
Because it's impossible to carry out million-year experiments, we instead
look at what evolution has produced and try to figure out what happened and
why. Nowhere has this been more difficult than in the study of speciation,
the process by which one species splits into two.

14. Universe as Doughnut: New Data, New Debate, NYTimes
Excerpt: But, according to the new map, there seems to be a limit to the
size of the waves, with none extending more than 60 degrees across the sky.
The effect was first noted as a puzzle in the COBE data, (¡K) and now
seems
confirmed.
If the universe were a guitar string, it would be missing its deepest
notes, (¡K), perhaps because it is not big enough to sustain them.
"The fact that there appears to be an angular cutoff hints at a special
distance scale in the universe," (¡K).
Universe as Doughnut: New Data, New Debate, Dennis Overbye, NYTimes, March
11, 2003
Excerpts: (¡K) Universe is spatially flat and 14 billion years old, with
an
energy density consisting of 30% matter and 70% dark energy (a smoothly
distributed component that varies slowly, if at all, as the Universe
expands). (¡K) Worse still, why is the total abundance of matter
comparable
to that of dark energy if they are changing rapidly with respect to each
other as the Universe expands? Furthermore, the leading candidate for dark
energy is vacuum energy, or the cosmological constant, for which
theoretical estimates disagree with observations by 120 orders of magnitude.

15. The Effects of Cenozoic Global Change on Squirrel Phylogeny, Science
Summary: Squirrels appear to be excellent indicators of environmental
history because they are one of a very small number of mammalian families
that is almost worldwide in distribution. Mercer and Roth (p. 1568) present
a comprehensive genus-level molecular phylogeny of the squirrel family.
They document striking chronological and geographic correspondence between
events of divergence and diversification in the squirrel family (Sciuridae)
and multiple tectonic, sea-level, and paleontological events documented in
the geological record. Their findings may help in the understanding of the
Cenozoic environmental and biogeographical history of such complex regions
as Southeast Asia and the American tropics.

Excerpt: Inbreeding in animals can increase their susceptibility to
pathogens, but direct evidence from wild populations is scarce and it is
unclear whether all pathogens are affected equally. Here we analyse rescued
California sea lions afflicted with a range of different pathogens, and
find that sick animals have higher-than-normal parental relatedness, with
the extent varying among disease classes. Our findings indicate that
mortality in natural populations may not be entirely random and that inbred
individuals could act as more effective reservoirs of infectious agents.

Excerpt: By most accounts, the North Atlantic called all the shots as the
world staggered out of the depths of the previous ice age 20,000 years ago.
When warm water surged back into the North Atlantic, the world began to
melt out of its deep freeze. When the flow of warm water shut down, the
world shivered again. Only after several such reversals did the world break
the ice's hold. But now there's an upstart challenging the North Atlantic
as a dominant global climate shifter.

16. Fishy Food Cuts Belching Beasts' Methane, New Scientist
Excerpts: Adding a dash of fish oil to animal fodder could help farmers
stifle the greenhouse gases wafting from their farmyards, (¡K). Switching
animals from regular feed onto a diet of fishy fodder cut the amount of
methane in their belches by nearly half. (¡K)
According to the US Environmental Protection Agency, belches from farmyard
animals account for around 22 per cent of global emissions of the
greenhouse gas methane. Volume for volume, methane traps nearly 20 times as
much heat as carbon dioxide, making it a potent contributor to global warming.

17. Making Faces, NYTimes
Excerpts: Once removed from a donor, a face, much like a heart, can survive
without adequate blood supply for only a matter of hours (¡K). With the
recipient's scar tissue removed and the essential arteries and veins
exposed, surgeons would attach them to the corresponding arteries and veins
in the harvested face in order to supply both nourishment and drainage.
(¡K). Should a human recipient's subsequent immunosuppression therapy
prove
successful, they would then face months, even years, of painful healing and
physical therapy just to achieve minimal function.
Making Faces, Charles Siebert, NYTimes, March 9, 2003
Excerpts: The technology scans and maps the human face as a
three-dimensional surface, providing a far more accurate reference for
identifying a person than current systems, most of which rely on
two-dimensional images, Kimmel said.
The product can potentially meet a wide range of security needs (¡K).
Kimmel and one of his former pupils, Assi Elad, had already developed the
algorithms used as building-blocks for the face-recognition system. The
Bronstein twins constructed a 3-D scanner, together with engineer Eyal
Gordon, and applied the ideas to face recognition.
Identical Twins Crack Face Recognition Puzzle, Michele Gershberg, Reuters,
03/03/09
Excerpts: Facial recognition technology has improved substantially since
2000, according to results released yesterday of a benchmark test by four
federal government agencies (¡K).
The data, which is the latest in a series of biannual tests overseen by the
National Institute of Standards and Technology, is expected to encourage
government security officers to deploy facial recognition systems in
combination with fingerprinting and other biometric systems for
applications like verifying that people are who they claim to be and
identifying unknown people by comparing them with a database of images.
Face-Recognition Technology Improves, Barnaby J. Feder, NYTimes, 03/03/14
Excerpts: By contrast, in biometric systems the appearance of the signature
matters little. Instead, it is the act of signing that counts. (¡K)
The idea of using handwriting dynamics to authenticate signatures is not
new. For several years, I.B.M. has sold a system based on the principle to
banks and other financial institutions to authorize computer transfers of
large amounts of money. But such systems use costly, specially made pens
and require the transfer of relatively large amounts of data, making them
impractical for retailers with thousands of cash registers.
Recognizing the Dance on the Dotted Line, Ian Austen, NYTimes, 03/03/13
18. Just War - or a Just War?, NYTimes
Excerpts: Profound changes have been taking place in American foreign
policy, reversing consistent bipartisan commitments that for more than two
centuries have earned our nation greatness. These commitments have been
predicated on basic religious principles, respect for international law,
and alliances that resulted in wise decisions and mutual restraint. Our
apparent determination to launch a war against Iraq, without international
support, is a violation of these premises. (¡K)
The war can be waged only as a last resort, (¡K). In the case of Iraq, (¡K)
alternatives to war exist.
Just War - or a Just War?, Jimmy Carter, NYTimes, 03/03/09
Excerpts: There are risks in this endeavor, (¡K).
But no one can plausibly argue that ridding the world of Saddam Hussein
will not significantly improve the stability of the region and the security
of American interests and values. Saddam Hussein is a risk-taking aggressor
who has attacked four countries, used chemical weapons against his own
people, professed a desire to harm the United States and its allies and,
even faced with the prospect of his regime's imminent destruction, has
still refused to abide by the Security Council demands that he disarm.

19. Complex Challenges: Global Terrorist Networks
Excerpts: In a 35-page ruling, the judge showed impatience and irritation
with the government over its failure to agree on conditions for a meeting
between Mr. Padilla and his lawyers. (¡K)
"Lest any confusion remain," the judge wrote, "this is not a
suggestion or
a request that Padilla be permitted to consult with counsel, and it is
certainly not an invitation to conduct a further `dialogue' about whether
he will be permitted to do so."
Judge Affirms Terror Suspect Must Meet With Lawyers, Benjamin Weiser,
NYTimes, 03/03/12
Excerpts: The United States military is holding hundreds of prisoners
accused of Taliban or Al Qaeda ties at Guantanamo. Many were seized in the
heat of battle, but others were turned over in exchange for rewards or
bounties. Advocates for the prisoners maintain that one-third or more are
being held on the basis of bad intelligence, (¡K).
Whatever their legal status, the Guantanamo detainees must be given a
chance to contest their confinement. Those who were wrongly caught up in
the military's net must have an opportunity to make their case.
Forsaken at Guantanamo, NYTimes, 03/03/12
Excerpt: In a notice published last month, the budget office asked experts
from around the country for ideas on how to measure "indirect costs"
like
lost time, lost privacy and even lost liberty that might stem from tougher
security regulations.
The budget office has not challenged any domestic security rules, and
officials say they are only beginning to look at how they might measure
costs of things like reduced privacy. But officials said they hoped to give
federal agencies guidance by the end of the year.
