Playing
Pass-the-Parcel
Its time for the robots now to hone their social etiquette
as a University of Hertfordshire team is working on how
future robot react in social situations by playing games,
like pass-the-parcel. The study's findings will eventually
help humans develop a code of social behaviour in human-robot
interaction. "We are assuming a situation in which
a useful human companion robot already exists. Our mission
is to look at how such a robot should be programmed to respect
personal spaces of humans," said Professor Kerstin
Dautenhahn, project leader at Hertfordshire. The research
also focuses on human perception of robots, including how
they should look and how a robot can learn new skills by
imitating a human demonstrator. "Without such studies,
you will build robots which might not respect the fact that
humans are individuals, have preferences and come from different
cultural backgrounds. And I want robots to treat humans
as human beings and not like other robots," Dautenhahn
added. The team aims to prepare robots to handle not one
but a number of people together and to do this they made
one robot to play pass-the-parcel with children. "If
you think of a robot as a companion for the human being,
you can think of 20 years into the future. It might take
even longer because it is very, very hard to develop such
a robot," concluded Professor Dautenhahn.
Scientists
Find Methane on Mars
A
European Space Agency team has detected methane gas on Mars,
the clearest indicator yet that there could be life there.
According to University of Michigan scientist, Sushil Atreya
who was a part of the team, "Biologically produced
methane is one of many possibilities. Ethane is a potential
biomarker. If a planet has methane we begin to think of
the possibility of life on the planet. On Earth, methane
is almost entirely derived from biological sources."
He added that methanogens, microbes that consume the Martian
hydrogen or carbon monoxide for energy and exhale methane
that dwell in colonies out of sight beneath the surface
of the red planet could be the possible source of Methane
getting to Mars. "These are anaerobic so they don't
need oxygen to survive, if they are there. If they are there,
they would be underground. While it's tantalising to think
there are living things on Mars, we aren't in a position
to say that is what is causing the methane," he said.
The instrument that sniffed out the methane detected an
average ten parts per billion by volume (ppbv) of methane
on Mars that was distributed unevenly over Mars' surface,
which tends to support the theory that an internal, on-site
source, rather than a comet, is the source generating the
methane.

Fill a Digital Camera
Memory Card Again
Epson's
new P-2000 Multimedia Storage Viewer features a 40GB hard
drive that you can use to store images from memory cards.
That means you don't have to worry about running out of
card space or carrying a notebook along. Just insert the
memory card into the P-2000, transfer the images, clear
the card, and start shooting again. Each of the two built-in
memory card slots supports CompactFlash Type I and Type
II and Secure Digital memory cards, and there's an optional
third-party adapter for additional cards. The P-2000 has
a 3.8in display for viewing Jpeg images. Its 40GB capacity
is enough to store about 5000 RAW-format images and up to
10,000 Jpeg images, according to Epson. The portable device
is designed to enable users to show off digital photos culled
from a computer or straight from the flash cards used by
popular cameras. Intended as a replacement for Epson's P-1000,
the P-2000 has higher-capacity storage, a faster interface
and the ability to play video and music files.

Are Human-Bacteria Hybrid
Most
of the cells in your body are not your own, nor are they
even human. They are bacterial. From the invisible strands
of fungi waiting to sprout between our toes, to the kilo
gram of bacterial matter in our guts, we are best viewed
as walking "super-organisms," highly complex conglomerations
of human cells, bacteria, fungi and viruses. That's the
view of scientists at Imperial College London describing
how these microbes interact with the body. Understanding
the workings of the superorganism, they say, is crucial
to the development of personalised medicine and health care
in the future because individuals can have very different
responses to drugs, depending on their microbial fauna.
More than 500 different species of bacteria exist in our
bodies, making up more than 100 trillion cells. Because
our bodies are made of only some several trillion human
cells, we are somewhat outnumbered by the aliens. It follows
that most of the genes in our bodies are from bacteria,
too. Luckily for us, the bacteria are on the whole commensal,
sharing our food but doing no real harm. In fact, they are
often beneficial: Our commensal bacteria protect us from
potentially dangerous infections. They do this through close
interaction with our immune systems. "We have known
for some time that many diseases are influenced by a variety
of factors, including both genetics and environment but
the concept of this superorganism could have a huge impact
on our understanding of disease processes," said Jeremy
Nicholson, a professor of biological chemistry at Imperial
College and leader of the study. Nicholson's colleague,
professor Ian Wilson from Astra Zeneca, believes the "human
super-organism" concept "could have a huge impact
on how we develop drugs, as individuals can have very different
responses to drug metabolism and toxicity." "The
microbes can influence things such as the pH levels in the
gut and the immune response, all of which can have effects
on the effectiveness of drugs," Wilson said. The Imperial
College research demonstrates what many -- from X Files
stalwarts to UFO fanatics -- have long claimed: We are not
alone. Specifically, the human genome does not carry enough
information on its own to determine key elements of our
own biology.

Turn into Gadget Geeks
The
next time you want to learn how to operate that complicated
looking gadget, try asking your grandmother and chances
are that she will decode it for you. A new survey has revealed
that the number of 50 year olds spending money on gadgets
is far greater than 30-year olds. The survey, conducted
by Lloyds TSB bank, found that older people are spending
money on updating themselves with the latest technology
like never before and they also take much more holidays
than the younger generation. According to the survey this
is because people who are over fifty are much more financially
and socially secure and are therefore able to make use of
the security. "Today's footloose over 50s are taking
full advantage of their financial and social freedom,"
the researchers as saying.
