Almost 140 years ago, Charles Darwin formalized what many people already believed - mate selection isn't pure chance; it's a deliberate process that involves numerous factors, including biological ones.
Darwin scored a scientific bullseye but a very big question has been, "What have we learned since then?"
Adam Jones, a Texas A&M University evolutionary biologist, says that Darwin's beliefs about the choice of mates and sexual selection being beyond mere chance have been proven correct, as stated in Darwin's landmark book "The Descent of Man, and Selection in Relation to Sex" in 1871. His work has withstood decades of analysis and scrutiny.
When you go to New York City, to Central Park, to the American Museum of Natural History, to the Hayden Planetarium, to a seminar hosted by Neil deGrasse Tyson, on the entire cosmos, you might think it would be hard to figure out who 'the star' will be.
PARIS, June 14 /PRNewswire/ --
Paris Air Show -- The Lockheed Martin (NYSE: LMT) team developing the U.S. Air Force's Global Positioning System (GPS) III program has entered the Critical Design Review (CDR) stage on-schedule, an extensive phase that precedes production of the next-generation satellite system.
Over the next year, Lockheed Martin Space Systems, Newtown, Pa., along with industry partners ITT, Clifton, N.J., and General Dynamics of Gilbert, Ariz. will conduct 70 individual CDRs for key GPS III spacecraft subsystems, assemblies and elements. The phase will culminate in the fall of 2010 with a final Space Vehicle CDR that will validate the detailed GPS III design to ensure it meets warfighter and civil requirements.
PARIS, June 14 /PRNewswire/ --
PARIS AIR SHOW -- Lockheed Martin (NYSE: LMT) announced today that it has delivered the final block of a new flight software architecture that will provide highly reliable spacecraft command and control operations for the Space-Based Infrared System (SBIRS) geosynchronous orbit (GEO) satellite constellation.
The SBIRS program is designed to provide early warning of missile launches, and simultaneously support other missions including missile defense, technical intelligence and battlespace awareness.
Conception is not a meeting of equals, as scientists have said for decades. The egg is a relatively large, impressive biological factory compared with the tiny sperm, which delivers to the egg one copy of the father's genes. However, the lack of parity may be less one sided than believed. A new study in Nature from Huntsman Cancer Institute (HCI) at the University of Utah reveals that the father's sperm delivers much more complex genetic material than previously thought.
Researchers discovered particular genes packaged in a special way within the sperm, and that may promote the development of the fetus.
Doom and gloom types always want to lament that the presence of people is killing the Earth. Not so, say California Institute of Technology (Caltech) scientists. At least on a cosmic scale, the presence of life may increase longevity for planets.
In traditional thinking, a billion years from now the ever-increasing radiation from the sun will have heated Earth into inhabitability, causing the carbon dioxide in the atmosphere that serves as food for plant to disappear. The oceans will evaporate and all living things will disappear.
Maybe not quite so soon, say researchers from Caltech, who have come up with a mechanism that doubles the future lifespan of the biosphere while also increasing the chance that advanced life will be found elsewhere in the universe.
Almost 90 percent of the world’s population will not have timely access to affordable supplies of vaccines and antiviral agents in the current influenza A (
H1N1) pandemic but inexpensive generic drugs that are readily available even in developing countries could save millions of lives, according to the conclusion reached by an extensive review and analysis by immunization expert Dr David Fedson within hours of the World Health Organization declaring a pandemic.
Newborn babies have immature immune systems, making them highly vulnerable to severe infections and unable to mount an effective immune response to most vaccines, thereby frustrating efforts to protect them. The World Health Organization estimates that more than 2 million newborns and infants less than 6 months of age die each year due to infection. Now, researchers at Children's Hospital Boston believe they have found a way to enhance the immune system at birth and boost newborns' vaccine responses, making infections like respiratory syncytial virus, pneumococcus and rotavirus much less of a threat.
Today I visited the 53rd international art exposition at the Biennale di Venezia, which this year is titled "Fare Mondi" (making worlds). I am posting below a few pictures I took of the installations I saw there, for those of you who are not insensitive to contemporary arts. But before I do, let me add a personal note.
