There may be a pattern . . . somewhere.

Encyclopedia of Life

In essence, EOL will be a microscope in reverse, or “macroscope,” helping users to discern large-scale patterns. By aggregating for analysis information on Earth’s estimated 1.8 million known species, scientists say the EOL could, for example, help map vectors of human disease, reveal mysteries behind longevity, suggest substitute plant pollinators for a swelling list of places where honeybees no longer provide that service, and foster strategies to slow the spread of invasive species.

Most importantly, the EOL will be a foundational resource for helping to conserve the species already known and to identify millions of additional species that haven’t yet been described or named. At its core is the knowledge about the world’s species that has been discovered by scientists over the last 250 years. By putting this information all together in one place, EOL hopes to accelerate our understanding of the world’s remaining biodiversity. . .

“The launch of the Encyclopedia of Life will have a profound and creative effect in science,” says Prof. Wilson. “It aims not only to summarize all that we know of Earth’s life forms, but also to accelerate the discovery of the vast array that remain unknown. This great effort promises to lay out new directions for research in every branch of biology.”

Krill living and feeding down to depths of 3,000 meters

Scientists have been studying krill since the ‘Discovery’ expeditions of the early 20th century. Oceanographic expeditions, using a combination of echo-sound techniques and collection samples in nets, indicated that the bulk of the population of adult krill is typically confined to the top 150 metres of the water column. . .

“The behaviour of marine organisms - even quite 'primitive' ones - can be complex and more varied than we usually assume. There is still a great deal to learn about the deep sea and an important role for exploration in our attempts to understand the world we live in.”

Corn genome's first draft

They identified almost 100 genes which have nearly identical copies in the genome. Schnable said these nearly identical paralogs may have played important roles during the evolution and domestication of corn and may have contributed to the ability of breeders to mold this important crop species to meet human needs. The Schnable and Aluru teams also discovered several hundred new corn genes that are not present in other plants. Some of these genes may be responsible for unique attributes of corn.

The corn genome is an especially difficult jigsaw puzzle to put together, Schnable said. There are some 2.5 billion base pairs that make up the double helix of corn DNA. The corn genome also has long lines of repetitive code. And corn has 50,000 to 60,000 genes to identify and characterize. That’s about twice the number of genes in humans. Plus, 50 percent or more of the corn genome is made up of transposons or jumping genes. Those are pieces of DNA that can move around the genome and change the function of genes. . .

The genome of corn is very similar to the genomes of rice, wheat, sorghum, prairie grasses and turf grasses. Therefore, Schnable said the draft of the corn genome can help researchers improve the other cereals and grasses.

Flaming Socks

Is it just me, or are the Oscars now a real bore due to the efficiency and general good taste of the whole show? . . .

I think they need to subcontract out some of the performative parts of the show, particularly the musical numbers, to the weakest or most self-delusional talents in Hollywood. It should be a requirement that there is a big mid-show dance number showcasing the most depressing and serious major nominee of the year. I would gladly stay up all night to see a big spectacular choreography called “I Drink Your Milkshake” that has oil-soaked dancers whirling around a wooden derrick while a guy on stilts stomps around them giving an evangelical sermon.

They should cut down the little speeches that the presenters give so they can budget more time for award-winners to say unpredictable or deranged things. There should be a requirement every year that the most certifiably crazed or self-deluded director, actor or producer be given 5 minutes on stage to say or do anything they want. . .

Also they need to designate a major nominee as the Too Authentic For Oscar every year, and send him or her off to some kind of designated exile for the night of the broadcast, pictured only by a still photograph taken approximately fifteen years ago. They could alternate between Paris, New York, Tibet, McMurdo Station and Darfur.

Perhaps the pattern will emerge during the day. Stay tuned.

Taster's Choice

A new primer written by scientists at the Monell Center and Florida State University and published in the February 26 issue of Current Biology, provides a clear and accessible overview of recent advances in understanding human taste perception and its underlying biology.

Within the past few years, identification of receptors for sweet, bitter and umami (savory) taste has led to new insights regarding how taste functions, but many questions remain to be answered. The Current Biology primer reviews the current state of knowledge regarding how taste stimuli are detected and ultimately translated by the nervous system into the perceptual experiences of sweet, sour, salty, bitter, and umami.

Such perceptual evaluations are related to the function and ultimately, the consequences, of taste evaluation. These can range from pleasurable emotional reactions, for example the delight a child receives from a sweet candy, to the critical life-dependent response that causes a person to spit out a bitter potential toxin.

Author Paul A.S. Breslin, PhD, a sensory scientist at the Monell Center, observes, “For all mammals, the collective influence of taste over a lifetime has a huge impact on pleasure, health, well being, and disease.

For example: The Ketchup Conundrum

To a worm in horseradish, the world is horseradish! . . .

"The mind," as Moskowitz is fond of saying, "knows not what the tongue wants." . . .

At Ragú and Prego, they had been striving for the platonic spaghetti sauce, and the platonic spaghetti sauce was thin and blended because that's the way they thought it was done in Italy. Cooking, on the industrial level, was consumed with the search for human universals. Once you start looking for the sources of human variability, though, the old orthodoxy goes out the window. Howard Moskowitz stood up to the Platonists and said there are no universals. . .

"If I make one group happier, I piss off another group. We did this for coffee with General Foods, and we found that if you create only one product the best you can get across all the segments is a 60—if you're lucky. That's if you were to treat everybody as one big happy family. But if I do the sensory segmentation, I can get 70, 71, 72. Is that big? Ahhh. It's a very big difference. In coffee, a 71 is something you'll die for." . . .

In the gourmet-ketchup world, there is River Run and Uncle Dave's, from Vermont, and Muir Glen Organic and Mrs. Tomato Head Roasted Garlic Peppercorn Catsup, in California, and dozens of others—and every year Heinz's overwhelming share of the ketchup market just grows. . .

There is an exception, then, to the Moskowitz rule. Happiness, in one sense, is a function of how closely our world conforms to the infinite variety of human preference. But that makes it easy to forget that sometimes happiness can be found in having what we've always had and everyone else is having. . . "I guess ketchup is ketchup."

Your brain on Krispy Kremes

New research from Northwestern University's Feinberg School of Medicine reveals how hunger works in the brain and the way neurons pull your strings to lunge for the sweet fried dough.

Krispy Kremes, in perhaps their first starring role in neurological research, helped lead to the discovery.

In the study, subjects were tested twice -- once after gorging on up to eight Krispy Kreme donuts until they couldn't eat anymore, and on another day after fasting for eight hours.

In both sessions, people were shown pictures of donuts and screwdrivers, while researchers examined their brains in fMRI's.

When the subjects saw pictures of donuts after the eating binge, their brains didn't register much interest. But after the fast, two areas of the brain leaped into action upon seeing the donuts. First, the limbic brain -- an ancestral part of the brain present in all animals from snakes to frogs to humans -- lit up like fireworks.

"That part of the brain is able to detect what is motivationally significant. It says, not only am I hungry, but here is food," said senior author Marsel Mesulam, M.D., the Ruth and Evelyn Dunbar Distinguished Professor of Psychiatry and Behavioral Sciences at the Feinberg School and a neurologist at Northwestern Memorial Hospital.

Next, the brain's spatial attention network shifted the hungry subject's focus toward the new object of desire -- in this case the Krispy Kremes.
