Wood-Shattering Revelation: Termites have been recategorized based on genetic and other evidence. Turns out, they are just social cockroaches and thus, have become part of the cockroach order Blattodea rather than remaining in a separate order. This decision was not made lightly, but based on years of debate amongst American entomologists. The insects will still retain termite in their name, but they gain a reputation for surviving apocalyptic events. Read about the update to the insect name master list by the Entomological Society of America.
Blood Pressure Measurements at the Tip of Your Finger: A blood pressure cuff is bulky, annoying but accurate for monitoring the effort needed for pushing blood around your body. While this device is a fairly simple one, in the developing world it is not that common. However, mobile phones are available to many more globally so why not find a way to put the two together? Turns out that smartphones are equipped with hardware that can be used to measure blood pressure. By adding a device that attaches to the back of a smartphone and with the press of a finger, you can monitor your blood pressure. While not currently as accurate as a blood pressure cuff, the people that tried the mobile blood pressure device were able to quickly adapt to using it, making it easy to take several readings for continuous monitoring. A pocket-sized blood pressure monitor without the nasty squeeze of your arm sounds like a great medical advancement for treating high blood pressure. See a video of the device.
For a Forensic ID, All You Needed Was a Picture, Old Clothing and Some Numbers: The quest to find where Amelia Earhart may have landed in the Pacific Ocean has been investigated and speculated about since she and her navigator disappeared July 2, 1937. In fact, skeletal remains had been found on a remote island in the South Pacific in 1940 along with other artifacts–a woman’s shoe, an American sextant box, but the bones were identified as a man by a physician at the time. Unfortunately, these remains have subsequently been lost. Recently, an anthropologist decided to take the measurements made in 1940, and using a modern-day techniques including a program that estimates stature, sex and ancestry, and he found that the bone measurements were more consistent with Earhart than with 99% of the reference sample used. In addition, using a photograph of the American pilot that had scale generated bone lengths of her humerus and radius and measuring her clothing from a collection gave a number for her tibia. All these numbers strongly suggest the skeletal remains were Earhart’s. Read the press release.
Means and Metrics for Detecting and Measuring Consciousness
A diverse panel of thought leaders in neuroscience and consciousness, from the chief scientist and president of the Allen Institute for Brain Science to the principal English translator for His Holiness the Dalai Lama, will explore Means and Metrics for Detecting and Measuring Consciousness at the 17th International Forum on Consciousness May 17–18, 2018, in Madison, Wisconsin. Presenters will discuss emerging technologies for looking into the phenomenon of consciousness such as sleep, wakefulness, altered states, focused attention, and coma. The Forum will ask how the ability to better measure consciousness may create opportunities to improve human function, resolve disease states, and keep the brain/mind healthier throughout all stages of life.

20 Years of Human Pluripotent Stem Cells: Current Clinical Trials and Regulatory Framework
April 18, 2018 | Madison, WI
Over the years, the BTC Institute has partnered with the Stem Cell & Regenerative Medicine Center, at the University of Wisconsin-Madison to offer this packed day of excellent talks and opportunities to interact with renowned speakers, poster session presenters, sponsor representatives and other attendees.
Our UW-Madison committee members define each year’s content and pull together a strong group of presenters. This year, we’re working with Timothy J. Kamp, M.D. (Professor, Medicine, Cell and Regenerative Biology; Co-director, Stem Cell and Regenerative Medicine Center), William L. Murphy, Ph.D. (Professor, Biomedical Engineering, Orthopedics & Rehabilitation; Co-director, Stem Cell & Regenerative Medicine Center) and James Thomson, Ph.D. (John D. MacArthur Professor, Director, Regenerative Biology, Morgridge Institute for Research; Professor, Department of Molecular, Cellular, & Developmental Biology, University of California – Santa Barbara).
Our 2018 symposium brings together leading researchers advancing human pluripotent stem cell products to clinical applications for a range of degenerative diseases. Progress in clinical trials, as well as major barriers for developing these revolutionary new therapies will be discussed.
Salmonella. Streptococcus. Shigella. The most well-known bacteria are those that cause disease. Our relationship with them is one of combat. With good reason, we look for ways to avoid encountering them and to eliminate them when we do meet.
But not all bacteria are bad for us. Of course we have known for years that we are colonized by harmless bacteria, but recently, studies on the human microbiome have revealed many surprising things about these bacterial tenants. Studies are showing that the teeming multitudes of organisms living in and on the human body are not just harmless bystanders, but complex, interrelated communities that can have profound effects on our health.
Three studies published last week in Science add more to the growing body of microbiome surprises, showing that certain gut bacteria are not only good for us, but may even be required for the effectiveness of some anti-cancer immunotherapies.
The Foundation for Food and Agriculture Research (FFAR) announced on November 30 that they are awarding $1M to a project based at the University of California, Davis, to study protein kinases of rice plants. The team is led by Dr. Pamela Ronald, a leading expert in plant genetics who has engineered disease- and flood-resistant rice. This project aims to address the growing agricultural problem of water scarcity by gaining a better understanding of the role kinases play in enabling drought-resistance. Promega will be supporting this research by providing NanoBRET™ products to help characterize kinase inhibitors.
The research team will begin by screening over 1,000 human kinase inhibitors to determine which ones do interact with the plant kinome and, if applicable, which kinase(s) they inhibit. Once the compound library has been established, the team will assess the inhibitors’ phenotypic effects on rice to identify kinases that, when inhibited, positively impact root growth and development. The long-term goal is to use these findings to engineer drought-resistant rice.
There have been many changes in sequencing technology over the course of my scientific career. In one of the research labs I rotated in as a graduate student, I assisted a third-year grad student with a manual radioactive sequencing gel because, I was told, “every student should run at least one in their career”. My first job after graduate school was as a research assistant in a lab that sequenced bacterial genomes. While I was the one creating shotgun libraries for the DNA sequencing pipeline, the sequencing reaction was performed using dideoxynucleotides labeled with fluorescent dyes and amplified in thermal cyclers. The resulting fragments were separated by manual loading on tall slab polyacrylamide gels (Applied Biosystems ABI 377s) or, once the lab got them running, capillary electrophoresis of four 96-well plates at a time (ABI 3700s).
Sequencing throughput has only increased since I left the lab. This was accomplished by increasing well density in a plate and number of capillaries for use in capillary electrophoresis, but more importantly, with the advent of the short read, massively parallel next-generation sequencing method. The next-gen or NGS technique decreased the time needed to sequence because many sequences were determined at the same time, significantly accelerating sequencing capacity. Instruments have also decreased in size as well as the price per base pair, a measurement used when I was in the lab. The long-prophesized threshold of $1,000 per genome has arrived. And now, according to a recent tweet from a Nanopore conference, you can add a sequencing module to your mobile device:
Welcome to the future – DNA sequencing on your mobile phone – imagine where and how you can use it. Hats off to the @nanopore team for getting this to work at this form factor, voltage and watts. https://t.co/Tm6A5fj8M4
You, like me, may occasionally find youself in need of a canine control device. While I’m not a fan of the dog tie out, I do walk dogs on leash—as is required by our county and city government here in Madison, WI.
If you have read Temple Grandin’s books about dogs, you might feel a tug at your heartstrings while enduring a tug on the leash. Aren’t dogs meant to run freely? Don’t we love to watch them run? Are leashes humane?
When walking dogs I feel the need to protect them, but also a desire to let them live like dogs, sniffing, marking and other behaviors that are all limited when the dog is leashed.
When a report in Science last week showed evidence that our ancient ancestors were using leashes 8,000-9,000 years ago I was: 1) surprised; and 2) felt vindicated from self-imposed dog owner guilt.
It’s late October and here in Wisconsin, like many of you, we are experiencing a change of seasons, with the associated drop in temperatures, changes in leaf color and later this week, Halloween.
Another thing that comes with fall is the start of cold and flu season. By “flu”, I mean influenza, caused by avian influenza viruses of the H-N type. Recent research results by teams at UWI-Madison and in Japan, makes the coming influenza season potentially more scary than usual.
In a recent Cell Host & Microbe paper, M. Imai et al. study a seemingly more virulent version of H7N9 avian influenza virus that is startling in its ability to spread from infected to healthy animal models. Based on a current epidemic of H7N9, human-to-human transmission with this strain is increasing. Continue reading “H7N9 Influenza Virus: A Perfect Pathogen?”
Correspondence whether via postcard or letter has been a method of human communication likely since people became literate. Old letters and postcards have been uncovered in attics, basements and garages, offering depth and richness to historical events or adding context to how humans lived in the past. But what about finding correspondence from more than a few hundred years ago?
Interestingly, archeologists were excavating in a Roman fort just south of Hadrian’s Wall and discovered well-preserved thin slices of wood with ink writing dating to the 1st century. While these 25 postcard-sized correspondence, found in a line about 3–4 meters long, are just the latest uncovered at the Vindolanda fort, the documents add to the history of Romans in Britain.
Many of the newly discovered wooden wafer postcards seemed to contain complete messages and could be read without the need for infrared photography. This treasure “hoard” of ancient Roman writing tablets offer insights such as a man named Masclus asking for leave. His previously discovered correspondence also from the Roman fort at Vindolanda included asking his commanding officer to supply more beer to his outpost.
The announcement of these 25 new Roman messages by the sponsors of the fort excavation are only preliminary overview of the find. In fact, archeologists are working on conserving and deciphering messages on the wooden tablets and plan on using infrared photography to reveal if there is any more writing on these postcards from the past.
Promega has become the first major forensic manufacturer to achieve third party certification of the published ISO 18385 standard to minimize the risk of human DNA contamination in products used to collect, store and analyze biological material for forensic purposes.
On February 2, 2016, ISO 18385:2016 was published as the first international standard specific to the forensic manufacturing community. Since the standard was published, companies have begun to self-declare that they comply with the ISO standard. Some companies have gone a step further and reached out to Certification Bodies to provide an unbiased and independent assessment their compliance to ISO18385 through a third-party audit.
When consumers see an ‘ISO 18385 Forensic Grade’ labeled product, it should inspire confidence that the product was produced in accordance with a minimum set of criteria common to all manufacturers.
