Researchers at the University of Iowa and Kansas State University say a deafness-causing gene defect in mice helped identify a new protein that protects sensory cells in the ear, according to findings in PLoS Genetics. 

In humans, hereditary deafness is one of the most common birth defects, yet most genes involved in hearing are unidentified. Mice are used as research models because mouse and human auditory genetics are very similar. 

Using a deaf mouse model generated at The Jackson Laboratory, the team identified the deafness-causing defect in the claudin-9 gene. The mutated gene fails to produce normal claudin-9 protein, which, the UI team showed, is needed to maintain the proper distribution of potassium in the inner ear.

We humans spend roughly one-third of our lives asleep but researchers don't know why. 

Science magazine listed the function of sleep is one of the 125 greatest unsolved mysteries in science and we've seen theories range from brain 'maintenance', including memory consolidation and pruning, to reversing damage from oxidative stress suffered while awake, to promoting longevity. None of these theories are well established, and many are mutually exclusive. 

Next year begins one of the largest and most important scientific experiments in history; the initial attempts at the National Ignition Facility (NIF) to produce the world's first controlled nuclear fusion reaction and tame the energy source of the sun.

That would mean a limitless new source of energy for homes, factories, and businesses.

We management professors are very conscious of the "professional school" label given to colleges of business, law, medicine, engineering, nursing, and education in diversified universities – universities in which some clinical fields, like psychology, may be part of the college of Arts&Sciences, and thereby on the other side of the divide. (At my alma mater, clinical psych is in A&S, and counseling psych is in the College of Education.)

Though a few verbal grenades are tossed over the divide each semester, schools on both sides generally co-exist tolerably well. What are the differences between them?

The Pacific Region of the American Association for the Advancement of Science (AAAS, "the world's largest general scientific society") includes some of the best universities in the world, located on the Pacific coast of the US. So it was with great excitement that I flew out to San Francisco to attend the 90th Pacific Regional Meeting of the AAAS at San Francisco State University (SFSU), where I was slated to give a talk on science blogging.

During the Miocene and Pliocene, 12-1.6 million years ago, a diverse group of extinct proboscideans, elephant-like animals walked the Earth. Most had four tusks and likely a trunk similar to modern elephants. They were beasts of legend, inspiring myths and stories of fanciful creatures to the first humans to encounter them.

Tomorrow, we are attending a mixer called The Science of Fine Wines.  This is a seminar/fundraiser for the Discovery Museum Science&Space Center in Sacramento so we're there to help with the science.  Sure, you can tell by the title the science is not the paramount issue, the wine is, but I'm always going to take the opportunity to get a little smarter and if other people listen, that's great too.

The figure shown below represents the best measurement of the top quark mass ever obtained by a single experiment, and it is a determination with a less than 1% total uncertainty. It has been approved last week by the CDF experiment at Fermilab.

The CDF experiments collects proton-antiproton collisions delivered by the Tevatron collider, which imparts the projectiles with 1 TeV of energy each, for a center-of-mass energy of 2 TeV. This is still the highest energy ever achieved by a collider, although the record is going to be soon stripped off Fermilab by the Large Hadron Collider, which is due to start colliding protons with other protons at 7 TeV of energy this coming fall.

The Lockerbie Injustice

To those victims’ relatives who can bear to hear me say this: they continue to have my sincere sympathy for the unimaginable loss that they have suffered.

To those who bear me ill will, I do not return that to you.

Abdul Ali al-Megrahi


Today, Abdul Ali al-Megrahi was released from prison on compassionate grounds.  I rejoice at that decision.  Ever since he was named as the Lockerbie bomber I have had exceedingly strong doubts that he was even so much as implicated, let alone the bomb-builder.  I would like to share my thoughts about this.

What is the difference between "intelligence" and "genius"?  Creativity, of course!
