I took a three week hiatus to do my phlebotomy practicum (which was kinda cool) and then dove back into school this week (which was awesome). My classes this semester are Clinical Microbiology and Hematology/Coagulation, which means I spend 20 hours a week in the lab, and another 15 or so studying outside the lab. Fortunately, I love the material, so it makes school much more enjoyable.<br />So now that school is in session, I will be focusing more on Med Lab stuff, though I won't completely abandon science news, especially if it's exciting.<br /><br />My first week of classes was mostly review, though they did cram a lot of new stuff down our throats, at least new to me. One teacher, who has been in the medical field all her life, and even took some med school classes at U of W, commented on how Med Techs know more about the medical laboratory then nurses and doctors (the exception being, of course, pathologists and other lab geeks). It certainly has been a crazy week. While in Hematology we're covering different microscope techniques and erythrocyte development, in Micro we mixed our own medias and did our first Gram stains.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjajHKMPliNH34XxhaQe9M31Hjs0m-XeND1eP46YWp_Wedq3AgNroQ3hYK1FqZ6wp-bb7RYDVg8dNxCjfJEB-AGVUhc4LQjELdhELNG9PVbNlgxk0VFzDjQC-jJMHJrC5AeogywydVFXJ4z/s1600-h/DSCI0557.JPG"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 254px; height: 320px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjajHKMPliNH34XxhaQe9M31Hjs0m-XeND1eP46YWp_Wedq3AgNroQ3hYK1FqZ6wp-bb7RYDVg8dNxCjfJEB-AGVUhc4LQjELdhELNG9PVbNlgxk0VFzDjQC-jJMHJrC5AeogywydVFXJ4z/s320/DSCI0557.JPG" alt="" id="BLOGGER_PHOTO_ID_5375565013958590306" border="0" /></a><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhpqa1I9lHpOFFESJyKtmfRzBptYdF8jlZfFRLEWlKDn-H0gYWmmDVy8xUOTOd5-P94ARgGhGE5TPFq_aRcw4BlbkRkYByUQoyoH6ykIpJ_xrkYAQfgT5-GROY-FGd2yL_38hm4l1mBhKum/s1600-h/DSCI0555.JPG"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 286px; height: 320px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhpqa1I9lHpOFFESJyKtmfRzBptYdF8jlZfFRLEWlKDn-H0gYWmmDVy8xUOTOd5-P94ARgGhGE5TPFq_aRcw4BlbkRkYByUQoyoH6ykIpJ_xrkYAQfgT5-GROY-FGd2yL_38hm4l1mBhKum/s320/DSCI0555.JPG" alt="" id="BLOGGER_PHOTO_ID_5375564999729293794" border="0" /></a><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj3myD7D6796BCV8k32dbNhnvpvNPoeylKVxDZ_6voPnmodxT4Vo-6loV9y7p8Doy3DVzzzdogIueDJfmzu-QevmOL4MW_TNFMW5CWVtwzbEzpkkZAneQ2bsVrFbZhyphenhyphenoDDfDpGVrtlZbQ25/s1600-h/DSCI0561.JPG"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 212px; height: 320px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj3myD7D6796BCV8k32dbNhnvpvNPoeylKVxDZ_6voPnmodxT4Vo-6loV9y7p8Doy3DVzzzdogIueDJfmzu-QevmOL4MW_TNFMW5CWVtwzbEzpkkZAneQ2bsVrFbZhyphenhyphenoDDfDpGVrtlZbQ25/s320/DSCI0561.JPG" alt="" id="BLOGGER_PHOTO_ID_5375564987616772450" border="0" /></a><br /><br />And for exciting science news: IBM scientists have taken the first picture of a molecule.

I looked into it and discovered that the bacterium she was referring to is actually <span style="font-style: italic;">Yersinia pestis</span>, which is responsible for the plague.<br />Yes, THE plague.<br />When <span style="font-style: italic;">Y. pesti</span>s gets into the lungs, its called the "pneumonic plague". And yes, it can kill you within 24 hours if it goes untreated. Administering antibiotics within the first 24 hours is critical.<br />The World Health Organization reports that between 1998 and 2008, nearly 24,000 cases were reported and around 2,000 deaths.

It was not known when and how they activate their unique system of traction. However, thanks to those geniuses at University of Calgary and Clemson University in South Carolina, we now have a better understanding of gecko feet. They discovered that geckos' amazing grip is triggered by gravity.<br />U of C biological sciences professor, Anthony Russel, says "Geckos use microscopic, hair-like filaments to attach to surfaces. Only at certain angles do they switch on their traction system." Geckos must be on an incline in order to trigger their adhesive system, which allows them to climb smooth surfaces at steep angles.<br />Learn more <a href="http://www.scienceblog.com/cms/new-angle-gecko-research-23735.html">here.</a><br /><br /><span style="font-weight: bold;">Kill Tumors with Nanotubes!</span><br />Scientists have discovered that injecting nanotubes into tumors and heating them with a 30-second zap of a laser effectively kills kidney tumors in nearly 80 percent of mice.

It's certainly not complete, but for beginning microbiology, it is a very handy tool.<br />Check it out: http://microbewiki.kenyon.edu/index.php/Taxonomy_Index<br /><br />In other microbiology news, scientists believe that the microbe "<span style=";font-family:Arial;font-size:85%;" >Methanosarcina barkeri</span>" may survive the martian atmosphere. M. barkeri is a methanogen (survives off of methane, which has been detected on Mars), is able to handle long dry spells and a wide range of temperature differences.<br />Learn more <a href="http://www.livescience.com/space/090718-survivor-microbe.html">here</a>.A.

They have now finally decided to name it Copernicus (Cp for short), after Nicolaus Copernicus, who discovered that the earth revolved around the sun.<br />Get excited <a href="http://www.livescience.com/environment/090714-copernicium-element.html">here</a>.<br /><br /> - Scientists have tracked down the genetic mutation which lead to blue eyes. All blue eyed people (including yours truly) are descended from a common ancestor who lived about 6,000 to 10,000 years ago. Before that, everyone was brown eyed. The mutation affects the OCA2 gene, which controls pigment production. It doesn't so much switch the gene off (which would cause albinism), but lessens the effect of the gene.

Researchers at the Ragon Institute of Massachusetts General Hospital (MGH), MIT and Harvard discovered that a receptor molecule involved in the first-line recognition of HIV-1 responds to the virus differently in women. This causes a subsequent differences in chronic T cell activation, which doctors use to predict disease progression. (Their paper will be published in an upcoming issue of Nature Medicine). The researchers focused on focused on plasmacytoid dendritic cells (pDCs), which are one of the first immune system cells to respond to HIV-1. They discovered the higher progesterone levels of premenopausal women correlated with increased activation of pDCs in response to HIV-1. Thus, the same amount of virus induces stronger pDC activation in women than in men. Learn more about the study <a href="http://www.scienceblog.com/cms/study-may-explain-why-hiv-progresses-faster-women-men-same-viral-load-22931.html">here</a>.<br /><br /> - Also in HIV/AIDS news, Brazil has proven that developing countries can indeed successfully treat and fight the HIV/AIDS pandemic. Their secret lies largely with inexpensive generic drugs. They also saved more than $1 billion as a result of bargaining with multinational pharmaceutical companies, having them lower their prices dramatically and encouraging generic companies to develop low-cost alternatives for emerging markets. Go Brazil!<br />Read the good news<a href="http://www.scienceblog.com/cms/brazil-proves-developing-countries-can-use-generic-medicines-fight-hivaids-epidemic-22958.html"> here</a>.<br /><br /> - In Alzheimer's news, a drug called PMX205 recovers memory in mice, and may be used one day for Alzheimer's treatment. PMX205 is similar to a drug used in clinical trials for rheumatoid arthritis and psoriasis. It prevents inflamed immune cells from gathering in brain regions with amyloid plaques.

Albert Uy (of Syracuse University) and his science minions have observed speciation in action, as two closely related populations of monarch flycatcher birds have split and are on their way to becoming two distinct species. Speciation has only been observed in action a handful of times, and is a central aspect of evolution (Bite me, creationists!). This is a fairly large endeavor, but it didn't phase Mr. Uy. Taking into account that the plumage of the two populations had changed (one is all black, the other has chestnut bellies), and that the males defend their mating territory and attack invading males, Uy and his team made models of the two bird populations. The all-black males attacked the all-black models, and paid little attention to the chestnut bellied models, and vice-versa. This indicates that the males do not consider the males of the other population a reproductive threat.<br />The birds also have a differing MC1R gene, which explains the change in plumage.<br />It's all gone to the birds <a href="http://www.scienceblog.com/cms/study-catches-2-bird-populations-they-split-seperate-species-22971.html">here</a>.<br /><br /> - Assistant Professor Li Hoi Yeung and Assistant Professor Koh Cheng Gee (along their team of science zombies) have discovered that during apoptosis (cell death) the cell's rescue mechanism is disabled when specific proteins can no longer enter the nucleus, which stops the cell from initiating it's self-repair process. This is actually a very important discovery in the world of biology, so be excited!<br />Oh, and they also discovered that the protein RanGTP, (involved in the transportation of certain proteins into and out of the cell's nucleus), is reduced greatly during the early stages of apoptosis. Just because they felt like rubbing in how smart and awesome they are.<br />Revel in the excitement <a href="http://www.scienceblog.com/cms/study-ntu-professors-provides-important-insight-apoptosis-or-programmed-cell-death-22967.html">here</a>.<br /><br /> - In the boggling world of physics, Yale University researchers have discovered a light force with repulsive power. It can be used to manipulate silicon microchip components, and may means that one day, nanodevices could run off of light instead of electricity.<br />Get excited and learn more <a href="http://www.scienceblog.com/cms/scientists-discover-light-force-push-power-22952.html">here</a>.<br /><br /> - Dr. Daniel Malone, (UA College of Pharmacy) mailed a questionnaire to 12,500 U.S. pharmaceutical prescribers who were selected based on a history of prescribing drugs associated with known potential for drug-drug interaction. (The prescribers were physicians, physicians' assistants and nurse practitioners.) He found that, on average, perscibers only correctly identified 42.7% of drug pairs with potentially dangerous drug-drug interactions.<br />Oops. Looks like med schools are focusing enough on drug-drug interactions.<br />Follow the shame <a href="http://www.scienceblog.com/cms/ua-pharmacy-research-shows-prescribers-miss-potentially-dangerous-drug-pairs-22937.html">here</a>.<br /><br />While I have respect for NASA and all the contributions they have made towards understanding the worlds around us, I have to give them a hard time for this: As the last components of the International Space Station are installed in 2110, they plan to de-orbit it in 2016.<br />Seriously guys. What they hell??<br />Billions of dollars have gone into this, and the final cost is estimated at $100,000,000,000. This is one of humanity's greatest monuments, a symbol of international collaboration in the name of science. There is no reason to take it down. It is more useful up in orbit then it is destroyed in a million little pieces as it reenters our atmosphere.<br />Get angry <a href="http://www.washingtonpost.com/wp-dyn/content/article/2009/07/12/AR2009071201977.html?hpid=topnews">here</a>.A.

It could even be possible to create sperm from female stem cells which would ultimately mean a woman having a baby without a man. It may also prove useful for young boys subjected to chemo treatment which left them infertile.<br />This is the first time human sperm has been created in a laboratory. The experiment has proved controversial and threatens to reignite the fierce debate of embryo research. Professor Nayernia, who heads the research, says "This is very amazing and very exciting. They have heads, they have tails and they move. The shape is not quite normal nor the movement, but they contain the proteins for egg activation." {He also claimed that his team has already used the technique on mice, which have produced offspring. The mice all died shortly after they were born.}<br />"Soon we will be able to isolate stem cells from the skin to generate sperm cells," he said. "This would enable us to look at individual stem cells from an infertile patient and find out what is the cause...We hope that eventually this could help create sperm for infertile men."<br /><br /><br /><object class="BrightcoveExperience" id="5775091" data="http://c.brightcove.com/services/viewer/federated_f9?&width=424&height=293&flashID=5775091&bgcolor=%23FFFFFF&playerID=4464161001&isVid=true&wmode=opaque&isUI=true&autoStart=false&%40playlistTabs=null&%40videoPlayer=28715623001&additionalAdTargetingParams=%3Bsite%3Dhealth%3Bsection%3Dhealth%2Fhealthnews%3Bpt%3Dst1%3Bpg%3D%2Fhealth%2Fhealthnews%2F5771061%2FHuman-sperm-created-from-stem-cells-in-world-first-claims-British-university.html%3Bspaceid%3Dvid%3Bls%3Df%3BtransactionID%3D0907130023130742" type="application/x-shockwave-flash" height="293" width="424"><param value="always" name="allowScriptAccess"><param value="true" name="allowFullScreen"><param value="false" name="seamlessTabbing"><param value="true" name="swliveconnect"><param value="opaque" name="wmode"><param value="high" name="quality"><param value="#FFFFFF" name="bgcolor"></object><br /><br />Learn more <a href="http://www.telegraph.co.uk/health/healthnews/5771061/Human-sperm-created-from-stem-cells-in-world-first-claims-British-university.html">Here</a>.A.

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.

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.<br />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.<br />Learn more @ http://www.scienceblog.com/cms/pinpointing-origin-gamma-rays-supermassive-black-hole-22754.html<br />http://veritas.sao.arizona.edu/<br />http://www.scienceblog.com/cms/vlba-locates-superenergetic-bursts-near-giant-black-hole-22755.html<br /><br />- Sometimes laws fail us, even in physics. Dr Tony Roberts and PhD student Christophe P. Haynes have shown that the fractal-Einstein and Alexander-Orbach laws can fail in some instances. Don't panic though; they derived a new law to replace them.<br />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.<br />Enjoy the science @ http://www.physorg.com/news166077673.html<br /><br />- Leiden theoretical physicists have used string theory to describe a physical phenomenon, something which has never been done before.

Dr. Horuzsko's microparticles suppress the dendritic cells, which makes the immune system ignore the organ.

Here is some cancer news to lift your mood.<br /><br />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."<br />The combination of these three measurements accurately estimates return cancer risk more accurately then any currently known method.<br />To learn more about the study which developed the method, go to:<br />http://www.scienceblog.com/cms/predicting-return-prostate-cancer-new-johns-hopkins-study-betters-odds-success-22748.html<br /><br />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.<br />For more information, go to:<br />http://www.scienceblog.com/cms/research-reveals-what-drives-lung-cancers-spread-22751.html<br /><br />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.<br />Learn more @ http://www.scienceblog.com/cms/gumc-discovery-highlights-new-direction-drug-discovery-22765.html<br /><br />Lets face it: Leukemia is a bitch. Acute myeloid leukemia is even worse. Fortunately, there's hope. Dr. John Dick of <strong style="font-weight: normal;">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 </strong>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.<br />Enjoy the science @ http://www.cell.com/cell-stem-cell/abstract/S1934-5909(09)00207-0<br />http://www.physorg.com/news166096568.html<br /><br />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.<br />Follow the excitement @ http://www.qimr.edu.au/<br />http://www.scienceblog.com/cms/australian-researchers-identify-genes-cause-melanoma-22777.html<br /><br /><script type="text/javascript"><br />digg_url = 'http://digg.com/general_sciences/Lab_Geek_Cancerous_Mondays';<br /></script><br /><script src="http://digg.com/tools/diggthis.js" type="text/javascript"></script>A.

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.<br />But we know the truth. They just want their own underground lair. ^_^<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjDPZkFCQA1gsfKulzWPVGIJSm1EDQwGtJBJtJEzMjg53rDxOZoMFdylJlrKNhIBT9NvA05FQJ-xWCwOwPlAoxxIgU-wCCx1kQHdoX6QQMOiQJrPbE1DHGB6clk0C1fCXlh6-EvNPVRnUm1/s1600-h/dusel_h800.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 320px; height: 202px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjDPZkFCQA1gsfKulzWPVGIJSm1EDQwGtJBJtJEzMjg53rDxOZoMFdylJlrKNhIBT9NvA05FQJ-xWCwOwPlAoxxIgU-wCCx1kQHdoX6QQMOiQJrPbE1DHGB6clk0C1fCXlh6-EvNPVRnUm1/s320/dusel_h800.jpg" alt="" id="BLOGGER_PHOTO_ID_5354019559860240482" border="0" /></a><br />Enjoy the Science @ http://io9.com/5301462/dark-matter-lab-dedicated-5000-feet-underground<br />And @: http://www.lbl.gov/nsd/homestake/<br /><script type="text/javascript"><br />digg_url = 'http://digg.com/general_sciences/Lab_Geek_Underground_Lair';<br /></script><br /><script src="http://digg.com/tools/diggthis.js" type="text/javascript"></script>A.
