Discovery of Bilaterian-Type Through-Guts in Cloudinomorphs from the Terminal Ediacaran Period
ARTICLE https://doi.org/10.1038/s41467-019-13882-z OPEN Discovery of bilaterian-type through-guts in cloudinomorphs from the terminal Ediacaran Period James D. Schiffbauer 1,2*, Tara Selly 1,2*, Sarah M. Jacquet 1, Rachel A. Merz3, Lyle L. Nelson4, Michael A. Strange5, Yaoping Cai6 & Emily F. Smith 4 The fossil record of the terminal Ediacaran Period is typified by the iconic index fossil Cloudina and its relatives. These tube-dwellers are presumed to be primitive metazoans, but resolving 1234567890():,; their phylogenetic identity has remained a point of contention. The root of the problem is a lack of diagnostic features; that is, phylogenetic interpretations have largely centered on the only available source of information—their external tubes. Here, using tomographic analyses of fossils from the Wood Canyon Formation (Nevada, USA), we report evidence of recog- nizable soft tissues within their external tubes. Although alternative interpretations are plausible, these internal cylindrical structures may be most appropriately interpreted as digestive tracts, which would be, to date, the earliest-known occurrence of such features in the fossil record. If this interpretation is correct, their nature as one-way through-guts not only provides evidence for establishing these fossils as definitive bilaterians but also has implications for the long-debated phylogenetic position of the broader cloudinomorphs. 1 Department of Geological Sciences, University of Missouri, Columbia, MO 65211, USA. 2 X-ray Microanalysis Core, University of Missouri, Columbia, MO 65211, USA. 3 Biology Department, Swarthmore College, Swarthmore, PA 19081, USA. 4 Department of Earth and Planetary Sciences, Johns Hopkins University, Baltimore, MD 21218, USA. -

What Toyota Has to Say About Wussy-Boys
What Toyota has to say about wussy-boys How could you doubt the manliness of Japanese men? Yes, I know, poor kid– Kamenashi Kazuya is Secret Garden’s posterchild for all that is confused and confusing in Japan. For the past several months my interest in gender issues in Japanese pop culture have had me following this topic of Soushokukei Danshi Nikushokukei Jyou, translated: Herbivore guys, carnivore girls. “Soushokukei danshi” describes a “trend” of ‘herbivore men’, or a group of young men (typically classified as being metrosexual) who are rejecting the typical guidelines of masculinity, and embracing an alternative style. It’s a type of Otomen syndrome, as it were, for anyone who has read the manga/seen the drama. Otomen follows the story of a young man who, on the outside appears to be a manly-man, but who secretly loves sewing, crochet, stuffed animals, strawberry parfaits and baking beautiful cakes. Soushokukei danshi have been described as being more “family oriented”, and being uninterested in women and dating. Next in line are the carnivorous girls, beautiful, intelligent, ambitious young women displaying all of the characteristics it seems the men should be displaying: charisma, confidence, focus, and guts. These go-getters have been described by the soushokukei danshi as being “scary” (I’m shaking in my boots already…). The typical dynamic spelled out by this phenomenon is a type of gender- role-reversal, where the herbivorous guys seem unable to get up the manly gumption to go after girls, but prefer to wait for the carnivorous beauty (as long as he’s not scared of her, that is) to hunt him down and snatch him up in one fell swoop (sounds okay to me…). -

Thank you! Teacher School Grade # of Time spent Comments Name students with box contents Background for the teacher… Background for digestion: Before we investigate the many different problems individuals can have with digestion, here’s how normal digestion works - What Is Digestion? Digestion is the complex process of turning the food you eat into the energy you need to survive. The digestive tract (or gut) is a long twisting tube that starts at the mouth and ends at the anus. It is made up of a series of muscles that coordinate the movement of food and other cells that produce enzymes and hormones to aid in the breakdown of food. For the purpose of this curriculum, we have focused our reference to “guts” primarily on the following 7 organs: small intestine, large intestine, stomach, liver, pancreas, appendix, and gall bladder. If you choose to use lesson extensions or further research with students, the other aspects of the digestive process can be investigated. Stop 1: The Mouth -The mouth is the beginning of the digestive system, and, in fact, digestion starts here before you even take the first bite of a meal. The smell of food triggers the salivary glands in your mouth to secrete saliva, causing your mouth to water. When you actually taste the food, saliva increases. Once you start chewing and breaking the food down into pieces small enough to be digested other mechanisms come into play. -
The PMA Technique: Finally! a Breakthrough for Visionaries and Go Getters!
powered by Great Ideas to Improve Your Life 950,000 Subscribers ...and Growing The PMA Technique: Finally! A Breakthrough for Visionaries and Go Getters! By Jacob Korthuis A New Human Awareness Transforming our inner drives and belief systems is the key to revolutionizing our personal reflections regarding health, self-improvement, relationships and behavior. For too long, we were not aware enough of the power and value of our inner environment and especially how to change negative beliefs and behavior into positive proactive energy. Now, through the groundbreaking Progressive Mental Alignment® (PMA) Technique, this tool is available to you. The PMA belief system transformation technique is based on the discovery of a new phenomenon called “Bad Clusters.” These clusters serve as subconscious neurophysiologic jamming stations, placing a negative sabotaging influence on more than 75% of our thoughts, belief systems, decisions, and behaviors. We all experience their effects when we’re suddenly taken out of our flow, or when insignificant things abruptly disturb our good mood and productivity. Everybody has these bad clusters in their subconscious. They work like computer viruses on all your operating systems. They also imprison large amounts of energy that would otherwise be freed for proactive use. We all carry a certain amount of emotional burdens in our backpack. But we don’t want constantly to be reminded of this misery. “You have to leave the past alone,” is a commonly heard expression. The recent discovery of bad clusters clearly shows that you may decide to leave the past alone, but the past won’t leave you alone as long as those bad clusters remain undetected! These particular hidden elements of the past make you sick and sabotage your behavior. -

BICYCLE SAFETY GUARDIANS, Bicycling Is Fun, Healthy, and a Great Family Activity
TIPS FOR PARENTS, BICYCLE SAFETY GUARDIANS, Bicycling is fun, healthy, and a great family activity. But a bicycle isn’t a toy; it’s a vehicle! AND KIDS Some bike crashes can cause serious injuries and most are related to the behavior of you (the bicyclist) or the motorist. There are a number of things you can do to prevent a crash, and protect your brain if a crash occurs. Safe Riding Tips Before riding, make sure you, your family, and the bicycles are ready to ride. Be a “Roll Model” for other adults and children. Remember to: ■ Wear a Bicycle Helmet. Everyone – at every age – should wear bicycle helmets. For more guidance on fitting a helmet, see the National Highway Traffic Safety Administration’s Fitting Your Bike Helmet. ■ Adjust Your Bicycle to Fit. Stand over your bicycle. There should be 1 to 2 inches between the rider and the top tube (bar) if using a road bike and 3 to 4 inches if using a mountain bike. The seat should be level front to back, and the height should be adjusted to allow a slight bend at the knee when the leg is fully extended. The handlebar height should be level with the seat. ■ Check Your Equipment. Before riding, inflate tires properly and check that the brakes work. ■ See and Be Seen. Whether daytime, dawn, dusk, bad weather, or at night, make yourself visible to others. Wear neon, fluorescent or other bright colors when riding, to be most easily seen. Wear something that reflects light, such as reflective tape or markings, or flashing lights. -

Gut Contents Analysis of Four Fish Species Collected in San Leandro Bay in August 2016. SFEI Contribution #900. San Francisco Estuary Institute, Richmond, CA. EXECUTIVE SUMMARY In support of PCB modeling for San Leandro Bay, a Priority Margin Unit (PMU) for PCB load reduction in the estuary, fish samples of four species (topsmelt, shiner perch, white croaker, and northern anchovy ) were obtained in August 2016 for both tissue analysis and examination of gut contents. The bay was sampled at eight locations, with a repeated sampling at one location (Airport Lagoon) for one species (topsmelt). Fish were measured, weighed, and dissected, and their gut contents examined microscopically. Topsmelt (9 samples, 188 specimens) had the greatest variety of food items, with gammarid amphipods and chain diatoms predominating. Some topsmelt, especially larger individuals, consumed macroalgae as a major dietary component. Two samples at two sites for shiner perch (20 fish each) had contents composed of close to 50% gammarids at both sites, but differed in proportions of bivalves and polychaetes among the important food items. The one sample of white croaker had consumed mostly gammarids, with fish and polychaetes ranking next in importance. A single sample of northern anchovy (20 fish analyzed) differed radically from the other species in consuming mainly a diatom that appears to have been filtered from the water column. -
