Birthdays!
Today, July 10th, is the 153rd birthday of Nikola Tesla, the inventor of the radio, alternating current electric power, and at least 278 other inventions. He is considered on of the greatest electrical engineers ever, and was an adversary of Thomas Edison who refused to pay Tesla for several patents he developed for the Edison company. He had an eccentric personality and in his later years made some very outlandish claims, causing his peers to write him off as a mad scientist.
Tesla died of heart failure on January 7, 1943. His ashes currently reside in the Tesla Museum in Belgrade, Serbia.
It was Tai Shan's birthday yesterday. Happy 4th birthday Tai Shan!
Tai Shan is the first panda to be born at the Smithsonian National Park Zoo and survive, making him the 3rd in the U.S. He is also a product of artificial insemination.
His four layer birthday cake is made up of ice, bamboo, shredded beets and beet juice, which took zoo nutritionists two weeks to design.
The Inner Life of a Cell

Sciency Tid-Bits
Studies have already shown that monkeys can string together different sounds to create "sentences," particularly one of alarm or warning. A new study now indicates that can also recognize poor grammar. By introducing a nonsense word as a suffix, and then later using it as a prefix, the monkeys recognized the difference.

One of the first things a science student learns about is Absolute Zero. But have you ever wondered about the range of known temperatures? How hot is the Sun? What is the hottest temperature achieved in a lab? How hot was the Big Bang?

They Say Sin Began With the Bite of an Apple.
And thus I have traversed to the dark side. I bought my first Mac. A 2.53 GHz Macbook Pro with a 13" screen, 4 GB memory, and 250 hard drive. (Yes, I was originally planning to go for the 320GB hard drive, but I figured I could just buy an external hard drive later to store old pictures and documents)
It also came with an 8GB iPod Touch, which, after 20 tense minutes, Ryan was able to coax to life.
So far I love it. It is small, light, fast, and efficient. I am still adjusting to the keyboard and controls though.
It is by no means a top-of-the-line Mac, but I expect it to last me for the next four years. I bought it a month sooner then I expected due to my current PC slowly becoming a worthless pile of circuit boards. I'm keeping it as a back up computer for those times when I really need a PC, but other then that, it is retired. Tomorrow I will start transferring files and pictures to the new computer, specifically all my lab notes and class lectures/presentations. This awesome computer will be overflowing with science!

White Tiger
Six months ago a stripless, pure white Bengal tiger was born in an African zoo. Both her parents carry the gene for white coloring. Zookeepers suspected stripes would develop within six months, but so far the cub remains without stripes. Such tigers are not known to current exist in the wild.

Sewer Blobs from Outer Space?
Or North Carolina.
Found during a sewer inspection in North Caroline, there was initial debate over whether these were bryozoans or tubifex worms. Most scientists agree now that they are tubifex worms, unless you are Sally Kern, who probably thinks this is a part of the homosexual agenda.
Here are more tubifax worms:

Vaccine
- Queensland Institute of Medical Research scientists are in the final stages of developing a vaccine for Group A Streptococcus (GAS) bacteria. Group A Strep, pictured on the right, is the cause of those annoying strep throat infections, as well as rheumatic fever and rheumatic heart disease. A successful GAS vaccine would greatly increase the public health. Good luck QIMR researchers, may we see your vaccine soon!

Physics & Astronomy
- The world of physics is buzzing with the discovery of an outburst of "very high energy" (VHE) gamma radiation from the galaxy Messier 87, also known as M 87. The VHE gamma radiation burst was accompanied by a strong rise of the radio flux measured from the direct vicinity of its super-massive black hole. The gamma rays have energies a trillion times higher than the energy of visible light. An international collaboration of 390 scientists detected and reported the events, using three arrays of 12-meter to 17-meter telescopes to detect the gamma rays and the Very Long Baseline Array, which detects radio waves with high precision.
M 87 is 50 million light-years from Earth and contains a super-massive black hole that is more than six billion times more massive than our Sun.

The laws are used to describe how particles diffuse in complex environments, which affects big scientific questions. Dr Roberts said particles in diffuse in complex environments in much the same way and choose the easiest path. Thus their spread was not uniform, as the old laws predicted.

Medicine
- Dr. Anatolij Horuzsko, a reproductive immunologist at the MCG Center for Molecular Chaperone/Radiobiology and Cancer Virology, has developed degradable microparticles which deliver the most powerful known form of HLA-G (a natural suppressor of the immune response) straight to dendritic cells. Dendritic cells usually tell the immune system to attack a new organ after a transplant, which leads to severe complications. Dr. Horuzsko's microparticles suppress the dendritic cells, which makes the immune system ignore the organ. This is a significant improvement over current anti-rejection medications and offers a specific tolerance.

Cancerous Mondays
Nobody likes Mondays. Here is some cancer news to lift your mood.
Because I am a lab geek, the lab geeky news comes first: John Hopkin's cancer experts have developed a successful 3-way combination to better predict the return of prostate cancer. This method examines "the length of time it takes for PSA (prostate-specific antigen) to double, Gleason score (a numeric indicator of prostate cancer aggressiveness as seen under the microscope), and the interval between surgical removal of the prostate and the first detectable PSA level."
The combination of these three measurements accurately estimates return cancer risk more accurately then any currently known method.
To learn more about the study which developed the method, go to:

Memorial Sloan-Kettering Cancer Center researchers have uncovered genetic variables which aid lung cancer's ability to quickly metastasize. To blame is a hyperactive WNT cellular pathway, which is surprisingly the same cellular pathway colorectal cancers use. Tumor-initiating mutations in the genes KRAS and EGFR depend on a hyperactive WNT pathway, as well as the genes HOXB9 and LEF.

Georgetown University Medical Center researchers has developed a drug which blocks the activity of the fusion protein responsible for Ewing's sarcoma. Today, most small molecule cancer drugs inhibit the intrinsic activity of a single protein. This drug take a different approach, by stopping two proteins from interacting. Because scientists have never been done before with a cancer-causing fusion protein, they hope to have a novel medical therapy in the future.

Lets face it: Leukemia is a bitch. Acute myeloid leukemia is even worse. Fortunately, there's hope. Dr. John Dick of the Ontario Cancer Institute, along with many other researchers from various nations, has developed a leukemia therapy which targets the protein CD123 on cancer stem cells which drive AML. This treatment is the first anti-cancer monoclonal antibody therapy that specifically targets cancer stem cells. Part of the therapy's success is that it targets the cancerous stem cells themselves, which are chemo-resistant and responsible for AML recurrence.

A new breakthrough in melanoma research was made by scientists at the Queensland Institute of Medical Research. They discovered two new genes which together double a person's melanoma risk. Alone, either gene carries a 25% increased risk. With 10,000 people diagnosed each year, Australia has the highest occurrence of melanoma in the world. In Queensland, an average of 7 people per day with this deadly skin cancer.

Underground Lair
Every nerd has long dreamed of having a secret, underground lair.
Sanford Laboratory scientists have one. Well, half of one, which is due to be completed by 2016. An awesome, Umbrella-Corporationesque lab dedicated to dark matter research is located 8000 feet underneath South Dakota mountains. Since any interfering radiation disrupts dark matter, scientists claim an underground lab is an ideal studying environment.
But we know the truth. They just want their own underground lair. ^_^

And a Few Thoughts Before I Go
I leave on a 12 hour ferry ride tonight to go celebrate Fourth of July with family, so I will be offline for the weekend. I know you'll miss me, but here is some news to keep you company on those long, lonely nights.
- Little kids know to fear two things: needles and ear infections. (Why? Because they hurt.) Good news for the little ones though: new research is paving the way for a vaccine for Otitis media. Not only that, it's completely needle free! Dr. Lauren Bakaletz, (director of the Center for Microbial Pathogenesis in The Research Institute at Nationwide Children’s Hospital) is working in collaboration with John Clements (Tulane University School of Medicine) to develop the droplet vaccine, which has already had successful trial on chinchillas.
Learn how it works @ http://www.sciencedaily.com/releases/2009/06/090630220515.htm
- Scientists have uncovered potential hope in Alzheimer medication development. They discovered evidence that a cluster of peptides may be responsible for the devastating disease. The peptide, Amyloid Beta 42, is part of the Amyloid Precursor Protein. It grows to form six unit rings, a pair of which is called a "dodecamer," which over time may rearrange itself into B-sheet structures. These B-sheets lead to the fibrils that form brain plaque, a tell-tale sign of Alzheimers and other neurodegenerative diseases.
Learn more @ http://www.physorg.com/news165687229.html
- Alheimer's patients have even more reason to rejoice, as researchers at the University of South Florida and James A. Haley Hospital have discovered a link between memory decline and blood stem cell growth factor. Granulocyte-colony stimulating factor (GCSF) is responsible for stimulating blood stem cell growth in the bone marrow. New evidence indicates that it also seems to reverse memory impairment.

And @ http://www.sciencedaily.com/releases/2009/07/090701160557.htm
- While some researchers are playing with peptides, or stimulating growth factors, Sanford researchers are looking for genes related to schizophrenia. Some diseases, such as Huntingtons, can be traced to a single genetic defect. Schizophrenia is difficult because it is believed to involve various interactions among a multitude of genes. But modern technology has finally pinpointed schizophrenia to a specific chromosomal region.

- Do you love playing in the sun, but fear the deadly wrath of melanoma? Well, with a death toll of nearly 50000 a year, no wonder you're afraid. Hope is right over the horizon though, in the form of a knight in shining armor known as: Herpes!
What?
It sounds like a pretty grim decision - herpes or skin cancer - but researchers are using a modified type of herpes virus in the fight against melanoma. Known as viral-gene therapy, they inject the virus into the tumor to kill it. So far, the results are fairly mixed, and the procedue is still undergoing clinical trials.
