Parasites don't get a lot of respect these days but we may have to reconsider that.  In spite of their nasty reputation, they may have given us the joy of sex.

What's so great about sex?

If you don't know, this article cannot help and even from an evolutionary perspective the answer is not as obvious as one might think.

Two studies published in Science Express show the analysis of gamma-rays from two dozen pulsars, including 16 discovered by  NASA's Fermi Gamma-ray Space Telescope. Fermi is the first spacecraft able to identify pulsars by their gamma-ray emissions alone.

A pulsar is the rapidly spinning and highly magnetized core left behind when a massive star explodes. Most of the currently cataloged pulsars, some 1800 of them, were found through their periodic radio emissions; pulses caused by narrow, lighthouse-like radio beams emanating from the pulsar's magnetic poles, according to current theory.

Even among giants Messier 87, with two to three billion times the mass of our sun, stands out, completely dominating the Virgo cluster.

A supermassive black hole exists in the center of Messier 87 and gigantic plasma flows shoot out from the vicinity of the black hole at close to light speed. Scientists have now observed, simultaneously in gamma and radio frequencies, this active galactic core region and in doing so discovered that the elementary particles are accelerated to extremely high energy levels in closest proximity to the black hole.

Mars, Incorporated, the global brand dealing primarily with chocolate, other candy and pet food (1), wants to discuss its cocoa sustainability program as part of a summer-long sustainability exhibition on Mainau Island - a botanical island famed locally for its flora and fauna and located in the middle of Lake Constance, Germany, one of Germany's most popular tourist destinations.

The exhibition, which opens today, follows on from the annual Lindau Nobel Laureate Meeting in Germany last week, in which Mars was a sponsor.

Six groups of scientists from the Departments of Biology and Chemistry at the University of York and the Astbury Centre for Structural and Molecular Biology, Faculty of Biological Sciences, at the University of Leeds have set out discover how a group of proteins that are highly effective at killing bacteria could hold the key to developing new types of antibiotics.

Researchers from the Universities of York and Leeds have been awarded £3.3m from the Biotechnology and Biological Sciences Research Council (BBSRC) to find out how a family of proteins known as colicins force their way into bacterial cells before destroying them.

Have a really smart kid who loves big trucks but you can't stand loud, growling voices with too much reverb in stadiums?   You're in luck.    MANTRA (The Manufacturing Technology Transporter) is a specially modified monster truck that is packed with the latest machinery and simulators rather than baseball caps and flannel shirts.

The 14 meter long MANTRA truck will take to the road with a dedicated team to demonstrate the manufacturing and assembly line technology of the future and help to inspire young people to take up careers in engineering.

If you read internet science in 2006, you'd have thought former president George W. Bush's limitations of use of embryonic stem cell lines had killed science.  In reality, embryonic stem cell research only received $15 million in US funding when the restrictions were imposed and it grew to billions per year during his presidency so some of that rhetoric was designed simply to engage in cultural spin and mobilize votes for Democrats.

With a Democrat president and a bulletproof majority in the Senate, culturally-inclined science bloggers can now instead focus on religion and maybe the few Republicans still out there and the rest of us can tackle serious issues, like how to educate people on stem cell research so they can make informed policy decisions.
