NOTE TO VIEWERS: In Chicago, Verizon download speeds reached a maximum above one gigabit per second, and median speeds in South Korea exceeded those in the U.S. The video above incorrectly says Chicago speeds maxed out above one gigabyte per second, and represents the median speeds in megabytes instead of megabits. In the global race for 5G, U.S. telecom firms have a unique disadvantage: limited access to the “goldilocks” band of radio frequencies. That's pushing U.S. firms toward a less practical version of 5G. WSJ explains the science and its implications.

Dialectical behavior therapy for adolescents and young adults (DBT) is a clinical program within the Young Adult and Family Center that targets high risk, multi-problem adolescents. We specialize in identifying and treating depression and risky behavior in adolescents, including self-injury, suicidal ideation and suicide attempts, substance use, binging and purging, risky sexual behavior, physical fighting, and other forms of risk-taking. DBT has been adapted by Alec Miller and Jill Rathus from Marsha Linehan’s initial conceptualization of DBT, which was developed for adults diagnosed with borderline personality disorder. Our adaptation follows the work of Miller and Rathus, who originally modified DBT for use with teens. Our program targets five areas: Confusion about self Impulsivity Emotional instability Interpersonal problems Parent-teen problems The treatment has been shown to be effective in treating self-harming adolescents with depression who demonstrate some traits of borderline personality disorder that are beyond that expected of typical adolescent development. Depression in adolescence is characterized by depressed or irritable mood, changes in appetite and sleep, withdrawal from and loss of interest in usual activities and friends, feelings of hopelessness and worthlessness, agitation and/or fatigue, difficulty concentrating, difficulty making decisions, and suicidal ideation. Some traits of borderline personality disorder that may be of concern to teens and parents include: unstable sense of self, unstable interpersonal relationships, inappropriate or uncontrollable anger or other emotions, serious mood swings, recurrent self-harm or and/or suicide attempts, chronic feelings of emptiness, and impulsivity that puts the teen at risk. Teens and young adults referred to the DBT Program typically have many or all of the problems listed above, which can lead to difficulties fulfilling their obligations in school and at home. This perpetuates their negative ideas about themselves.

Submit your real-time PCR questions at Just how does TaqMan work? Sr. Field Applications Specialist Doug Rains explores the specific mechanism by which TaqMan® achieves its unparalleled specificity and sensitivity. Around the world, researchers rely on TaqMan® for gene expression, SNP gentoyping , protein expression, pathogen detection and quantification, and more. For many years, TaqMan has been the gold-standard chemistry for real-time PCR. It's famed for its unparalleled specificity, sensitivity, and ease of use. So it's not surprising that users want to know what Shrikant at ICL College in India asked recently: namely, How does TaqMan work? I'm glad you asked. Just like any PCR, TaqMan-based reactions require a double-stranded template, as well as two fairly standard, target-specific primers. But unlike those used in regular PCR, TaqMan Assays require a third, sequence-specific oligo called a probe. TaqMan probes are quite different from the primers in two ways. First, they can't be extended by our friendly enzyme, Taq Polymerase, since they lack a free hydroxyl group. What's more, TaqMan probes are covalently joined to two other molecules. On the 5'-end, there's a fluorescent molecule known as the reporter -- called that because it reports signal to us as we generate more and more product. On the 3'-end is a molecule known as the quencher, which quenches the fluorescent signal from the reporter under certain circumstances. Let's see what those circumstances are. Here we're looking at an intact probe, with the reporter in green, the quencher in red. Normally, when we zap the probe with light, we expect the reporter to get excited and fluoresce. But because the quencher is in close proximity to the reporter, instead what happens is, the energy gets transferred from reporter to quencher. The transfer of energy is known as FRET, or Fluorescent Resonance Energy Transfer. The important thing to note here is that, as long as the probe remains intact, there is no permanent increase in fluorescent signal from the reporter. However, if the reporter and quencher are permanently separated during the reaction, and then light strikes the reaction, the Reporter does in fact fluoresce, producing signal the instrument can detect. The basic idea, then, is this: each time we create a new PCR amplicon, we want to permanently split the reporter and quencher. By doing so, florescence will always increase proportionally with product, allowing us to effectively monitor what's happening to our reactions throughout the run. Here it is in action. We begin our reactions (CLICK) by denaturing our template at a high temperature. As we lower the temperature, our probe and primers bind. Taq now comes in, finds the primers, and begins the extension phase of PCR by creating new complementary strands of DNA. But wait a second: there's a probe sitting in the way. It's a showdown in the making! What will the polymerase do? Stop in its tracks? Turn back in fear? Nay, friends, not Taq Polymerase. You see, our enzyme has what's referred to as exonuclease activity. Meaning? It pretty much eats DNA for lunch. So when Taq reaches the probe, it simply chews it to bits on its way to creating new amplicon. As a result, the reporter and quencher are physically separated, creating a permanent increase in fluorescence that, not coincidentally, perfectly accords with our doubling of product. And, of course, that our real-time instrument can monitor and record this increase in fluorescence after each cycle, generating an amplification plot that's more than a little useful for interpreting our data.

See how this groundbreaking technology works. Leveraging consumer technology for scientific breakthroughs Ion Torrent™ technology takes an entirely new approach to sequencing, making it faster, simpler, and more affordable than ever before. Unlike other sequencing technologies, Ion Torrent™ systems sequence DNA using a semiconductor chip, similar to the chip found in your digital camera. While the chip in your camera has a sensing layer covered with millions of pixels that translate light into digital information, an Ion chip has millions of wells covering those pixels. Whenever a nucleotide is incorporated into a single strand of DNA, a hydrogen ion is released. This is how the Ion Torrent system sequences DNA, by reading this chemical change directly in the well on the chip. In essence, each well works as the world's smallest pH meter.

Download the free Sanger sequencing handbook at If you have more questions on sequencing, submit your question at Let’s go back to the basics and explore the technology platform that has been regarded as the gold standard for many years. Yea, you guessed it! I am talking about Sanger Sequencing by capillary electrophoresis. Many might ask, “why is it called Sanger Sequencing?” Sanger Sequencing is named after the inventor of this ground breaking technology, Dr. Frederick Sanger, who developed this method over 40 years ago in the mid-70s. So, what are the basics of Sanger Sequencing? It all starts by having a short primer binding next to the region of interest. In the presence of the 4 nucleotides, the polymerase will extend the primer by adding on the complementary nucleotide from the template DNA strand. To find the exact composition of the DNA sequence, we need to bring this reaction to a defined stop that allows us to identify the base of the very end of this particular DNA fragment. Sanger did this by removing an oxygen atom from the ribonucleotide. Such a nucleotide is called a dideoxynucleotide. This is analogous to throwing a wrench into a gear. The polymerase enzyme can no longer add normal nucleotides onto this DNA chain. The extension has stopped and we now need to identify what it is. We identify the chain terminating nucleotide by a specific fluorescent dye, 4 specific colors to be exact. Sanger sequencing results in the formation of extension products of various lengths terminated with dideoxynucleotides at the 3′ end. The extension products are then separated by Capillary Electrophoresis or CE. The molecules are injected by an electrical current into a long glass capillary filled with a gel polymer. During CE, an electrical field is applied so that the negatively charged DNA fragments move toward the positive electrode. The speed at which a DNA fragment migrates through the medium is inversely proportional to its molecular weight. This process can separate the extension products by size at a resolution of one base. A laser excites the dye labeled DNA fragments as they pass through a tiny window at the end of the capillary. The excited dye emits a light at a characteristic wavelength that is detected by a light sensor. Software can then interpret the detected signal and translate it into a base call. When the sequencing reaction is performed in the presence of all four terminated nucleotides, you eventually get a pool of DNA fragments that are measured and separated base by base. What you will get in the end is a data file showing the sequence of the DNA in a colorful electropherogram and a text file which you can use to answer the questions you may be asking. And that in a nutshell is Sanger Sequencing.

In this example, the standards consist of a 10-fold dilution series ranging from 50 ng/ul down to 5 pg/ul. During each PCR cycle, the amount of fluorescent signal for each standard in the dilution seies is measured. When the fluorescent signal crosses the detection threshold the cycle number is recorded as a Ct value, or threshold cycle value. The Ct value is what ultimately is used to create the standard curve. The Ct values are inversely proportional to the concentration of DNA in the standards. The high-concentration, 50 ng/ul standard will cross the detection threshold first, generating a “low” Ct. The low-concentration, 5 pg/ul standard will take many more cycles to cross the same threshold - and therefore the Ct will be higher. The Ct values for each dilution of the standard curve are plotted on a graph, and the software generates a regression line that fits the data. Because the standards are 10-fold dilutions, we expect the change in Ct from one standard to the next to be uniform. An uneven distribution of Ct values might indicate that the dilution series was not accurately pipetted. Let’s take a look at the standard curve for a specific DNA target, the small autosomal target. The X axis is the log of the known standard concentrations. The Y axis is the Ct value of each standard. Now, Do you see the quality metrics at the bottom of the screen? Let’s review Slope, Y intercept, and R2.? The slope measures the efficiency of the PCR reaction. In a perfect world, a slope of -3.3 indicates that the PCR reaction is 100% efficient; the target DNA is doubled each cycle. Two copies become four; four become eight; and so on. The Y intercept is the expected Ct value for a 1ng/ul sample. The R2 value measures how well the regression line fits the data points. A line that fits the data points perfectly has an R2 of 1. If your data points are scattered, the R2 value for the line will be lower. The Ct values of your standards affect the slope, the Y intercept, and the R2 value. It is very important to prepare the standard dilution series carefully to ensure consistent and accurate results! Running the standards in duplicate can help ensure you have a high quality standard curve. Once your standard curve passes the metrics test, it can be used to evaluate an unknown sample! The Ct value of the unknown sample is measured, and compared to the standard curve to estimate the DNA concentration of the unknown sample. Couldn’t be simpler! That’s it for today.

Submit your question at What do you call a collection of millions of DNA fragments sharing the same short sequences on the 5’ and 3’ ends? The answer is a next generation sequencing, or NGS, library. Today, we are going to focus on the four basic steps of NGS library preparation that can be broadly applied across different preparation methods. A key step in the NGS workflow is preparing the input for sequencing, known as creating a library. An NGS library is a collection of similarly sized DNA fragments with known adapter sequences added to the 5’ and 3’ ends. A library corresponds to a single sample and multiple libraries, each with their own unique adapter sequences, can be pooled and sequenced in the same sequencing run. NGS library preparation has four general steps: 1. DNA Fragmentation or Target Selection, 2. Addition of adapter sequences, 3. Size selection, and 4. Final library quantification and QC. Let’s take a look at our lab book The first step, DNA fragmentation or Target Selection. In order to get the starting DNA into smaller pieces, isolated DNA may be fragmented using physical or enzymatic methods. These libraries are referred to as fragment libraries. Alternatively, if the sequence of specific DNA targets is known, PCR amplification of those targets may be used to produce DNA amplicons within the desired size range. These libraries are referred to as amplicon libraries. Next, specific DNA adapter sequences are annealed to the 5’ and 3’ ends of the fragmented or amplicon DNA. The double-stranded DNA adapters are approximately 20 to 40bp fragments that contain known sequences. Generally, there are two different adapter sequences that can anneal to the DNA fragments in either the 5’ or 3’ orientation. One adapter sequence contains the primer annealing site for the sequencing primer, while the second adapter sequence is generally used to anchor the DNA fragment to a surface for sequencing; for example beads or a solid surface containing a complimentary DNA sequence. Now we have our DNA fragments with known adapter sequences on either end. The next step is to select the library fragment sizes we need for our sequencing run. There are two common size selection methods, the first is a gel electrophoresis based-method, while the second is bead-based size selection method. For the gel-based method, the adapted library fragments are run on a gel to separate the fragments by size and the band corresponding to the size of interest is collected. Using the bead-based method, magnetic beads are used with varying concentrations of buffers to isolate the DNA fragment sizes of interest. Final library fragment size is important for efficient, high quality DNA sequencing downstream. Bonus, when preparing amplicon libraries, size selection is usually not necessary, as long as the PCR products were already designed to be within the desired size range. We are almost done! The last and very important step is library quantification and QC. Accurate library quantification is important for successful template preparation and sequencing. There are a few library quantification methods commonly used. The first is analysis by the BioanalyzerTM system. This method gives you both library concentration and fragment size information. The second is qPCR. This method provides the most accurate library quantification information, as it only measures amplifiable library fragments, but lacks library size information. Which method you prefer is entirely up to you (and probably what’s available in your lab). And that’s NGS library preparation in a nutshell. Of course there are variations on this theme depending on your application, for example, gene expression or DNA methylation analysis, but the fundamentals stay the same. Since your library quality dictates the success of all downstream processes from template preparation to sequencing, understanding the library preparation is important to help ensure you get the highest quality sequencing data. I hope this video was helpful on NGS library, and I am sure you’ll have more questions. Submit your question at thermofisher.com/ask and subscribe to our channel to see more videos like this.

Dr. Kristin Patzkowsky, a minimally invasive surgeon from the department of Gynecology and Obstetrics answers your common questions asked about endometriosis. Learn more at: Endometriosis is a benign disorder characterized by the presence of endometrial tissue (the tissue that lines the uterus) outside the uterine cavity where it becomes attached to reproductive or abdominal organs. The patches of endometrial tissue swell with blood during menstruation as if they were still in the uterus. Endometriosis is a common disorder, most prevalent between the ages of 25 and 40. Symptoms vary and are not strictly correlated with the severity of the disease; they may worsen with time, but tend to diminish during pregnancy and cease with menopause. Many women have no symptoms at all. Treatment depends on the severity of symptoms, the age of the woman, and whether she wishes to have children. Questions Answered: 1. What is endometriosis? 0:03 2.
