Super Sperm - An Evolutionary Reason For Infertility?

Super Sperm - An Evolutionary Reason For Infertility?

Sep 08 2009 | comment(s)

About 10% of couples who want a baby have fertility problems and causes offered tend to break down around advocacy issues; environmentalists blame pollution while psychiatrists point to our stressful lifestyles, but evolutionary biologist Dr. Oren Hasson of Tel Aviv University's Department of Zoology has a different take than the others, though also based on his speciality.

The reproductive organs of men and women are currently involved in an evolutionary arms race, he says in a new study, and the fight isn't over yet.

Biofuel have a great potential but turnig food into biofuel is not correct way instead work on the petroplants, local plants and search for non edible oil plants like Jatropha etc
as source of biofuel and improve their agrotechnology of production extraction purification and conversion. Invite people to suggest extraction procedures for petrocrops and optimise yield of Jatropha curcas.

Sometimes I come to think this blog is overextended: it happens when I realize it contains more things than I can remember, even ones I would really like to have at my fingertips. I was reminded yesterday of a very funny story which a reader left in the comments thread of a rather meaningless post, and decided I should make a separate post of it, since it made my day reading it and it might make yours too...

The story was told by Leon Lederman in an introduction to Carlo Rubbia in the proceedings of a conference held in 1984 in Santa Fe:

"... Now I have some interesting news, a story that is at the least apocryphal. It concerns the heroic contestant in one of those ancient trials by strength which are so natural for our "Carlo". This trial was

A sample survey was conducted in a cluster of 4 villages.10 families from each village were questioned for the survey. The main objective of the survey was to do a scenario analysis of the fuel used for cooking purpose and it’s interrelation with the background of the family in order to assess the following:<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Microbiology Takes On Oil Spills

Microbiology Takes On Oil Spills

Sep 08 2009 | comment(s)

Microbiologists from the University of Essex have shown they can break down and remove toxic compounds from crude oil and tar sands using microbes. These acidic compounds persist in the environment, taking up to 10 years to break down.

Tar sand deposits contain the world’s largest supply of oil. With dwindling supplies of high quality light crude oil, oil producers are looking towards alternative oil supplies such as heavy crude oils and super heavy crudes like tar sands. However, the process of oil extraction and subsequent refining produces high concentrations of toxic by-products.

"Jatropha Is Not Competing with Existing Food Crops to Produce Biodiesel”



The biofuel market is growing, and with it the development of certain crops to meet energy needs. One of which is Jatropha, a plant that is gaining importance in this sector.

An international team of scientists has not only verified the existence of a mountain range that is suspected to have caused the massive East Antarctic Ice Sheet to form, but also has created a detailed picture of the rugged landscape buried under more than four kilometers (2.5 miles) of ice.

Money Won't Buy Happiness (Though You Can Park Your Yacht Right Next To It)

You've heard the saying that money won't buy happiness; of course, that is true though some of it is also sweet lemons rationalization.   

So why is it that so many special interest groups insist they need more money or special treatment in order to be happy?   

Professor Mariano Rojas from Mexico's Facultad Latinoamericana de Ciencias Sociales  agrees and says that public policy programs aiming to tackle poverty need to move beyond simply raising people's income - because there's more to quality of life than money.

Salmonella typhi, the bacteria that causes typhoid fever, is obviously dangerous, with some 13 million people contracting typhoid fever annually,  fatally for 500,000 of them.

Sanitation is the primary cause.   For Americans there are under 500 fewer cases per year, most of those coming from visits to Mexico and South America.   It is also more common in India, Pakistan, and Egypt.

District 9: Private World Government and Our Future

Sep 08 2009 | comment(s)

The 2009 movie District 9 is a metaphor for what might be an evolved version of the world federalist government we have today.  Some time before the 1990s, conflicts were mainly fought between nationalized groups.  However the private province of war has taken over.  Now our wars are a contract of service, and history shows that the interests of private military firms have no contractual boundaries. To some, what may go unnoticed is that there are more contractors than there are public soldiers in our conflicts today. This is an unusual yet expected trend in the evolution of military affairs. It's gone from private soldiers in ancient Egypt to a booming corporate market, according to P. W.

A once-in-a-lifetime opportunity in citizen science was certainly not on the minds of 6-year-old Alyson Yates and her mom, Kate, when they stepped out into their back yard one day to scout for ladybugs.

Force & Motion- 5th Grade Style (DAY 1)

Started a unit on Force&Motion with my 5th grade class last week.  So far they are loving it!  My general style is to let them discover and play first, and explain the science behind it later.  If we start out reading about concepts or a lecture style, it generally goes over their heads.  If they have the hands on experiences first- then they can connect the 'jargon' to what they experienced.

Monkey See, Monkey Empathize? The quest for elusive human mirror neurons is on
By Brian Grone | September 7th 2009 06:38 PM | Print | E-mail
In 1992, a group of Italian neuroscientists reported that macaque monkeys have neurons that fire not only when a monkey picks up a peanut but also when the monkey watches a human pick up a peanut [1]. Mamma mia! Mirror neurons! Do these neurons, which fire while both seeing and doing an activity, provide a biological basis for empathy?
