Aunt Cam in all its glory! Always more beautiful every time I find it, now it takes me to strange places to show me his passion for photography! I trust her even more now that I'm (still) single, and it's nice to have someone who listens and advises as well. I love you Aunt Cam!

Proof of Heaven: A Neurosurgeon's Journey into the Afterlife

I have long been fascinated by the convergence of science and spirituality, ever since experiencing physical healing through prayer as a child. Growing up as a Christian Scientist, it was very normal to think of God as ever present Love and mankind as spiritual beings at the core.

I very much appreciate the courage that Dr. Alexander has shown for sharing this experience with us. There are "miracles" going on around us every day, but the unique combination of elements in his story (the fact that he was a neurosurgeon who held a materialist view, and that he understood ‘the brain so well that he could readily see that his experience was impossible if an explanation was: attempted though reductionist science) means that he could have a real impact on the future of study in this area.

For those who come to this book with an open mind, I fail to see how it will not have a profound impact on how they view the most important questions related to meaning, purpose and existence.

The Petit Appetit Cookbook... For helping me with the baby of my friends!

I recently purchased this book along with another like it and have found this one to be my favorite! How easy is it to make your own babyfood? Well, if you can make a grilled cheese, you can make your own baby food with, just as the author states, pretty much stuff you probably already have in the kitchen!
The introductory chapters provide a good deal of information on knowing when to start your baby on solids, differentiating the various definitions of organic goods and what not to feed (and why) just to name a few topics. The recipes are divided up into feeding stage appropriate sections with both fruits and veggies listed as pediatricians often differ on which one should be started first. The recipes themselves are super easy and while the daugther of my friends is trying to figure out whether or not she likes certain things, I find the taste of some of the foods to be pretty pleasant. As far as cost savings. I prepared an apple puree the other day with 3 lbs of organic red delicious apples ($3) and ended up with probably $20 (if I had to purchase) in food and it took very little time!

Out tha city

Sometimes, I wanna get out of my city, for long ride on my reddish rocket, to greenish and more more quiet parks, it's pleasant, and of course, I'm not alone in this field, people want silence! So, maybe we can cross our trails one time!

Proteomic Analysis of Mussels Exposed to Fresh and Weathered Prestige’s Oil

Biomonitoring programs that use mussels to assess the water quality around the world could benefit from the use of proteomics techniques. These could be applied to obtain protein expression signatures of exposure to pollution that could be further used for prediction purposes. This would require that a combination of univariate and multivariate statistical analyses of proteomics data were utilized to obtain robust models. We show an application of this approach on mussels exposed to fresh fuel, and weathered fuel in a laboratory experiment that tried to mimic the effects of the Prestige’s oil spill. By the combination of those statistical analyses, a set of protein spots were selected that could be used to classify mussels exposed to the two types of fuel oil. As an example of the possibilities that this approach could offer to biomonitoring programs, mussels were collected from ten sampling stations along the NW and NE coasts of the Iberian Peninsula, and their protein expression patterns monitored.

Roses from my friend...

This is a gift from Sullivane, the most beautiful woman  never seen, the most perfect girl I know, and a wonderful friend! She send me roses and you can be sure, I scream for the rest of the day, scream and cry, because it's not everyday that a surprise like that arrive! Thank you Sullie!!!

Blueberry Juice

Blueberries contain high levels of naturally occurring antioxidants that protect the body against cell damaging free radicals. Previous animal studies have shown that blueberry juice improves memory and even reduces high blood sugar in animals. Researchers are now reporting that blueberry juice improves memory in humans.

The study was conducted with elderly adults who were experiencing early memory decline. The results showed that drinking 2-2 1/2 cups of store bought blueberry juice a day improves memory. Participants who consumed blueberry juice not only showed improvement on memory tests, but their overall learning ability was enhanced as well.

A day with Thùy!

It was just a to-short day with my school sister Thùy! She came from Vietnam with many stories on our families and friends, we go to the park and take the day for speaking, laughing and screaming! It was so nice, so cool and refreshing! Go back Thùy! I love you so much my school sister!!!

XMAS !!!

For those who celebrate this day...
Happy Christmaaaaaaaaaas!!!!

Climate Influences Deep Sea Populations

In a new article Joan B. Company and colleagues at the Institut de Ciències del Mar (CSIC) in Spain describe a mechanism of interaction across ecosystems showing how a climate-driven phenomenon originated in shelf environments controls the biological processes of a deep-sea living resource.

The progressive depletion of world fisheries is one of the key socio-economical issues of the forthcoming century. However, amid this worrying scenario, Company's study demonstrates how a climate-induced phenomenon occurring at a decadal time-scale, such as the formation of dense shelf waters and its subsequent downslope cascading can repeatedly reverse the general trend of overexploitation of a deep-sea living resource.

Strong downslope currents associated with intense cascading events displace the population of the shrimp Aristeus antennatus from the fishing grounds, producing a temporary fishery collapse. However, nutritive particles brought by cascading waters to deep regions cause an enhancement of its recruitment process and an increase of its total landings during the following years.
These new findings resolve the paradox of a long-overexploited fishery that has not collapsed after 70 years of intense deep-sea trawling. The results will have a high socio-economic impact, since this species is the most valuable deep-sea living resource in the Mediterranean Sea. Because the cascading of dense water from continental shelves is a global phenomenon whose effects on biological processes were not considered in the past, it is hypothesized that its influence on deep-sea ecosystems and fisheries worldwide should be more important than previously thought.
In this sense, applying the findings to a global fishery scenario, shelf water cascading sites identified worldwide could be considered as regions favorable for deep-sea demersal fisheries, just as the upwelling zones are considered favorable regions for pelagic fisheries. This paper is particularly timely, since these new results will be of special relevance to the current debate on the shift from shelf to deep-sea fisheries.

Scientists have confirmed the existence of protein in soft tissue recovered from the fossil bones of a 68 million-year-old Tyrannosaurus rex (T. rex) and a half-million-year-old mastodon.

Their results may change the way people think about fossil preservation and present a new method for studying diseases in which identification of proteins is important, such as cancer.
When an animal dies, protein immediately begins to degrade and, in the case of fossils, is slowly replaced by mineral. This substitution process was thought to be complete by 1 million years. Researchers at North Carolina State University (NCSU) and Harvard Medical School now know otherwise.
The researchers' findings appear as companion papers in this week's issue of the journal Science.
"Not only was protein detectably present in these fossils, the preserved material was in good enough condition that it could be identified," said Paul Filmer, program director in the National Science Foundation (NSF) Division of Earth Sciences, which funded the research. "We now know much more about what conditions proteins can survive in. It turns out that some proteins can survive for very long time periods, far longer than anyone predicted."
Mary Schweitzer of NCSU and the North Carolina Museum of Natural Sciences discovered soft tissue in the leg bone of a T. rex and other fossils recovered from the Hell Creek sediment formation in Montana.
After her chemical and molecular analyses of the tissue indicated that original protein fragments might be preserved, she turned to colleagues John Asara and Lewis Cantley of Harvard Medical School, to see if they could confirm her suspicions by finding the amino acid used to make collagen, a fibrous protein found in bone.
Bone is a composite material, consisting of both protein and mineral. In modern bones, when minerals are removed, a collagen matrix--fibrous, resilient material that gives the bones structure and flexibility--is left behind. When Schweitzer demineralized the T. rex bone, she was surprised to find such a matrix, because current theories of fossilization held that no original organic material could survive that long.

"This information will help us learn more about evolutionary relationships, about how preservation happens, and about how molecules degrade over time, which could have important applications in medicine," Schweitzer said.
o see if the material had characteristics indicating the presence of collagen, which is plentiful, durable and has been recovered from other fossil materials, the scientists examined the resulting soft tissue with electron microscopy and atomic force microscopy. They then tested it against various antibodies that are known to react with collagen. Identifying collagen would indicate that it is original to T. rex--that the tissue contains remnants of the molecules produced by the dinosaur.

"This is the breakthrough that says it's possible to get sequences beyond 1 million years," said Cantley. "At 68 million years, it's still possible."

Asara and Cantley successfully sequenced portions of the dinosaur and mastodon proteins, identifying the amino acids and confirming that the material was collagen. When they compared the collagen sequences to a database that contains existing sequences from modern species, they found that the T. rex sequence had similarities to those of chickens, and that the mastodon was more closely related to mammals, including the African elephant.
The protein fragments in the T. rex fossil appear to most closely match amino acid sequences found in collagen of present-day chickens, lending support to the idea that birds and dinosaurs are evolutionarily related.

"Most people believe that birds evolved from dinosaurs, but that's based on the 'architecture' of the bones," Asara said. "This finding allows us the ability to say that they really are related because their sequences are related."

"Scientists had long assumed that the material in fossil bones would not be preserved after millions of years of burial," said Enriqueta Barrera, program director in NSF's Division of Earth Sciences. "This discovery has implications for the study of similarly well-preserved fossil material."

The research was also funded by grants from the David and Lucille Packard Foundation, the Paul F. Glenn Foundation and Beth Israel Deaconess Medical Center.

Pac Man Frogs

A giant frog fossil from Madagascar dubbed Beelzebufo or 'the frog from Hell' has been identified by scientists from University College London and Stony Brook University, New York. The discovery of the 70 million year-old fossil frog, of a kind once thought unique to South America, lends weight to a new theory that Madagascar, India and South America were linked until late in the Age of Dinosaurs.

The new frog resembles living Horned toads (ceratophryines or 'pac-man frogs') in having a squat body, huge head and wide mouth. With a body length (not counting the legs) of up to 40 cm -- longer than a rugby ball - and a weight of around four kilos (10 pounds), it is more than twice the size of its largest living relatives.
The fossil, published in the journal PNAS, enters the Malagasy history books alongside meat-eating dinosaurs, plant-eating crocodiles and giant snakes, all very different from the present day animals of Madagascar.
Professor Susan Evans of the UCL Department of Cell & Developmental Biology says: "This frog, a relative of today's Horned toads, would have been the size of a slightly squashed beach-ball, with short legs and a big mouth. If it shared the aggressive temperament and 'sit-and-wait' ambush tactics of living Horned toads, it would have been a formidable predator on small animals. Its diet would most likely have consisted of insects and small vertebrates like lizards, but it's not impossible that Beelzebufo might even have munched on hatchling or juvenile dinosaurs.

"Beelzebufo appears to be a very close relative of a group of South American frogs known as 'ceratophyrines,' or 'pac-man' frogs, because of their immense mouths," said Krause. The ceratophryines are known to camouflage themselves in their surroundings, then ambush predators.

"The finding presents a real puzzle biogeographically, particularly because of the poor fossil record of frogs on southern continents," said Stony Brook University paleontologist David Krause, who led the research. "We're asking ourselves, 'What's a 'South American' frog doing half-way around the world, in Madagascar?'"

He said that because frogs "are not adept at dispersal across marine barriers, and since the few fossil frogs that are known from the Late Cretaceous in Africa are unrelated to Beelzebufo, one possibility is that there was a land connection between South America and Madagascar during that period."
Some geoscientists have suggested a lingering physical link between South America and Madagascar during the Late Cretaceous Period -- a link involving Antarctica. Antarctica in the Late Cretaceous was much warmer than it is today.

"The occurrence of this frog in Madagascar and its relatives' existence in South America provides strong evidence that the supercontinent Gondwana 'disassembled' during the latest part of the Cretaceous," said Richard Lane, program director in NSF's Division of Earth Sciences.

"Madagascar has a mainly endemic frog fauna whose history has generated intense debate, fuelled by recent phylogenetic studies and the near absence of a fossil record. Our discovery of a frog strikingly different from today's Madagascan frogs, and akin to the Horned toads previously considered endemic to South America, lends weight to the controversial paleobiogeographical model suggesting that Madagascar, the Indian subcontinent and South America were linked well into the Late Cretaceous. It also suggests that the initial spread of such beasts began earlier than that proposed by recent estimates."

A new dating method finally is allowing archaeologists to incorporate rock paintings — some of the most mysterious and personalized remnants of ancient cultures — into the tapestry of evidence used to study life in prehistoric times.

In the study, Marvin W. Rowe points out that rock paintings, or pictographs, are among the most difficult archaeological artifacts to date. They lack the high levels of organic material needed to assess a pictograph's age using radiocarbon dating, the standard archaeological technique for more than a half-century.
Rowe describes a new, highly sensitive dating method, called accelerator mass spectrometry, that requires only 0.05 milligrams of carbon (the weight of 50 specks of dust). That's much less than the several grams of carbon needed with radiocarbon dating.
The research included analyzing pictographs from numerous countries over a span of 15 years. It validates the method and allows rock painting to join bones, pottery and other artifacts that tell secrets of ancient societies, Rowe said. "Because of the prior lack of methods for dating rock art, archaeologists had almost completely ignored it before the 1990s," he explained. "But with the ability to obtain reliable radiocarbon dates on pictographs, archaeologists have now begun to incorporate rock art into a broader study that includes other cultural remains.
