By Joel N. Shurkin, Inside Science - In an analogy many scientists hate, the human brain is often compared to a small, wet computer, functioning in almost the same way as the electronic kind. Two scientists at Cornell University report the analogy might be closer to the truth than anyone thought.

They have found an emotion code.

An investigational drug known as APT102 significantly reduced damage to heart muscle from a heart attack and minimized the risk of bleeding during follow-up treatments, according to an animal study based on a decade of work by APT Therapeutics, scientists at Washington University School of Medicine in St. Louis and colleagues at Cornell and Harvard.

Standard heart attack treatment often causes heart tissue damage. Once the blood clot that causes a heart attack is removed from an artery, molecules from dead and dying cells mix with blood rushing back through the artery. One of these molecules, adenosine triphosphate (ATP), is inflammatory; another, adenosine diphosphate (ADP), causes more clotting.

Isaac Asimov's Three Laws Of Robotics, from the story "Runaround" in 1942, are arguably the most famous example of fictional ethics becoming so fundamental they are adopted spontaneously by everyone in an industry that hadn't even been created yet.(1)

Now that robots are widely used in caring for older people, as well as in military and industrial applications, scholars want to give them a 21st century update.

In European culture, it is widely accepted that magpies (Pica pica) are the thieves of the bird kingdom, attracted to sparkly things and prone to stealing them for their nests.

But psychologists at the Centre for Research in Animal Behaviour (CRAB) at the University of Exeter have analyzed magpies and found that the species is actually frightened of new and unfamiliar objects rather than attracted to them. 

The researchers carried out a series of experiments with both a group of magpies which had come from a rescue center, and wild magpies in the grounds of the University. The birds were exposed to both shiny and non-shiny items and their reactions recorded. 

It sounds like science fiction, but a new paper in the journal BioEssays
 says that bacteria within us — which outnumber our own cells about 100-fold — may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity. 

The scholars from UC San Francisco, Arizona State University and University of New Mexico concluded that from a review of the recent scientific literature that microbes influence human eating behavior and dietary choices to favor consumption of the particular nutrients they grow best on, rather than simply passively living off whatever nutrients we choose to send their way.

There has always been a bit of good-natured humor when it comes to who gets credit for what in a long line of citations.

Occasionally, it can be strange, like when one person who contributed to the I.P.C.C. claims to be a Nobel laureate, but most often there is a pecking order to science papers.

This does not keep science humorosts like Jorge Cham at PhDComics.com from cutting to the heart of the matter, as they did on figuring out citations way back in 2005:

There's evidence that a child's future health is influenced by more than just their parents' genetic material and can be impacted by environmental factors, but what is being done with that is something of a concern.

Astronomers have produced new maps of the material located between the stars in the Milky Way, which could move science closer to cracking a stardust puzzle nearly a century old.

 The researchers say their work demonstrates a new way of uncovering the location and eventually the composition of the interstellar medium—the material found in the vast expanse between star systems within a galaxy. 

This material includes dust and gas composed of atoms and molecules that are left behind when a star dies. The material also supplies the building blocks for new stars and planets.

Laser physicists have found a way to make atomic-force microscope probes 20 times more sensitive, using laser beams to cool a nanowire probe to minus 265 degrees Celsius. 

Atomic force microscopes achieve extraordinarily sensitivity measurements of microscopic features by scanning a wire probe over a surface.
The technique makes it capable of detecting forces as small as the weight of an individual virus.

The development could be used to improve the resolution of atomic-force microscopes, which are the state-of-the-art tool for measuring nanoscopic structures and the tiny forces between molecules.

Transport accounts for an up to 30% of CO2 emissions in the EU, with estimates claiming that emissions from that sector rose 36% between 1990 and 2007. 

A new analysis conducted by Lund University and the University of Surrey takes on the widely-held view that new technologies, such as biofuel and improved aircraft design, will result in carbon reduction targets being met.
