Amazing Body Facts

first_imgThere are more wonders in your body than you can possibly imagine.  Here are half a dozen new findings for conversation starters.Your inner bat:  You have another sense you may not be aware of: you can learn the art of echolocation.   It’s been known that blind people develop an ability to detect objects by their echoes, but Science Daily reported that even sighted people can train themselves to do it.  Some people are better at it than others, for unknown reasons.  Echolocation depends on very precise detection of timing differences between the two ears.Self-healing holes:  Our blood vessels are made of a wonderful tissue, called epithelium.  It’s stretchy, stable, and watertight.  Science Daily says, “Measuring just a few hundred nanometers in thickness, this super-tenuous structure routinely withstands blood flow, hydrostatic pressure, stretch and tissue compression to create a unique and highly dynamic barrier that maintains the organization necessary to partition tissues from the body’s circulatory system.”But there are immune cells, called leukocytes, that need to enter these passageways.  How do they do it?  The article presented findings by the Beth Israel Deaconess Medical Center, where scientists studied how epithelial cells cooperate with leukocytes, creating holes for them to enter, then healing the holes behind them.By and large, these ensuing “micro -wounds” are short-lived; as soon as the cells have crossed the endothelium, these pores and gaps quickly heal, restoring the system’s efficient barrier function. In cases when these gaps fail to close — and leakage occurs — the results can be devastating, leading to dramatic pathologies including sepsis and acute lung injury….Described in The Journal of Cell Biology, the new findings suggest that rather than structural robustness per se, the barrier function of the endothelium relies on an enormous self-restorative capacity….“The cell’s restorative capacity was just so striking,” says [Christopher V.] Carman. “But these early investigations were still inadequate to tell us how the breaches were being closed. We had to dig down to the sub-cellular level to understand the underlying activities and the molecular signaling mechanisms that were orchestrating these activities.“Viruses, your friends:  You have another immune system scientists did not realize till recently, and it involves partnership with viruses.  Nature News reported that “Viruses in the gut protect from infection.”  Bacteriophages, tiny viruses that can invade and kill bacteria, find a home among the linings in your airways, by forming bonds with sugars in the mucus.  When bacteria invade, these killing machines, like a robotic army, take them out.  Medical Xpress called this a “new immune system” that has been discovered.  In more general terms, Science Magazine reviewed “our viral inheritance,” giving examples of good and bad ways that viruses interact with our bodies.  Even some endogenous retroviruses (ERVs) that seemed at first to be parasitic on our genomes now appear to be useful or beneficial.Nose knowledge:  The sense of smell continues to be one of the most difficult to understand in humans and in fruit flies.  The molecules that land on olfactory receptors encode messages that are in some ways similar to those in the retina, but there appear to be timing dependences, too, Medical Xpress reported.  Science Magazine reviewed the growing science of “flavor,” trying to understand how we learn to associate smells and tastes with pleasure or displeasure.  “It’s a vastly more complex topic than they once thought,” the article said.Your inner clock: We share a sense with the little flies we swat on our arms: a biological clock.  Because the human circadian clock is much more complex, scientists try to understand the clock in fruit flies.  Medical Xpress reported that a new component of the fruit fly circadian clock has been identified.Six degrees of separation:  Because the brain is so heavily interconnected, any synapse is only about six steps away from any other.  This allows for an enormous amount of plasticity for “rewiring” circuits when one part is damaged.  Science Daily discussed work at UCLA that shows the brain “rewires itself after damage or injury.”  Understanding these processes could lead to therapies for stroke victims and Alzheimer’s patients.  Last week, Science Magazine discussed “Why adults need new brain cells.”  Contrary to beliefs decades ago, neuroscientists now know that brain cell regeneration takes place.  Not only that, “a key function of adult neurogenesis is to shape neuronal connectivity in the brain according to individual needs,” the article said.  Because of the brain’s plasticity and massively parallel architecture, Sandia Labs is looking to the human brain as “a model for supercomputers,” PhysOrg reported.To make a point without attempting to be morbid, these findings underscore why the death of a human being, whether in a tornado or an abortion lab, is such a traumatic thing.  It’s like smashing a supercomputer, destroying a working factory, obliterating a work of art.  A dead body returns to undifferentiated dust that fulfills none of these fantastically complex processes.The Bible describes death as an enemy, the result of sin that infected the planet with a curse and judgment.  The only hope of a new body that can live forever is faith in Jesus Christ, who paved the way for salvation through His death and resurrection (I Corinthians 15).  If you marvel at the body you have now, “Eye has not seen, nor ear heard, nor have entered into the heart of man the things which God has prepared for those who love Him”  (I Corinthians 2:9).

How AgriPOWER inspired me to become a county board member — AgriPOWER Session 2 blog

first_imgShare Facebook Twitter Google + LinkedIn Pinterest  Leave a CommentBy Doug Franz, AgriPOWER Class X participantSession two of AgriPOWER Class X was held in Findlay, Ohio. All 17 members were present and engaged in various trainings and informative sessions to broaden our knowledge of current issues facing the agriculture community. There was a strong focus on media relations and legislative engagement, but what peaked my interest the most was our sessions on leadership. Several guest instructors focused on the importance of developing leaders within the agriculture community. Coming from a long military career, I have a vested interest in learning from, and developing effective leaders at all levels. Why is this important? Because effective leaders have the ability to shape the future of initiatives they become engaged in, regardless of the basis.  Effective leaders adapt to the environment and make decisions based on the analysis of facts and implement those decisions through the influence of others. The U.S. Army defines leadership as “the process of influencing people by providing purpose, direction, and motivation while operating to accomplish the mission and improve the organization”.  I think this is a clear, descriptive definition that holds true for almost any situation where leaders are needed.Based on my recent AgriPOWER trainings on leadership, and my years in military leadership roles, I decided that I should do something that puts those skills to use in my community. While attending my county Farm Bureau annual meeting last week, I noticed the district in which I reside did not have any candidates on the ballot for that board position. I inquired and soon became a write-in candidate for the elections that evening and was voted in by those in attendance! I am excited about this new opportunity to say the least. Without the recent AgriPOWER exposure to current events in the industry, I don’t feel I would have stepped up to perform this role. Thank you AgriPOWER for selecting me to be part of this program and I look forward to putting my new knowledge base to work in my local community!Other AgriPOWER Class X blogsJacob Hoelscher learns about the importance of agvocacy.Laramie Wells discusses Farm Bureau’s roots.Lindsey Walls describes the care taken to raise pigs.Megan Dresbach is ready to change the misperceptions about agriculture.    Leave a Commentlast_img read more

Illumio releases new templates that offer better security

first_imgInternet of Things Makes it Easier to Steal You… Adaptive security company Illumio, the just released Illumio Security Templates, offering ready-to-use security policies for core data center and cloud applications. They are pre-made to secure common applications, providing segmentation without having to reconfigure the network.These templates can be quickly used to secure applications including Exchange, Microsoft Active Directory, Microsoft SharePoint, Microsoft SQL Server and MongoDB rapidly.These tested and validated policy packages are downloadable, and they provide all the segmentation rules required to write a security policy for common enterprise applications or application components.See Also: Cyber security expert Schneier warns of impending IoT disasterA lot of programs, regardless of whether they are used in existing data centers or cloud computing environments such as Amazon Web Services, Microsoft Azure, or Google Compute Engine, need IT to constantly write fresh policies for every application and its parts by plumbing the allowed IP addresses and port/process connections for each service. This method takes a lot of time, and leaves room for errors, which can cause delays and security issues that often add days or weeks to the deployment process.Vice President of Product Management, Matthew Glenn, explains, “Illumio’s Security Templates let security and operations teams be as agile as they need to be.”He goes on to state, “With ‘push-button’ policies, IT no longer needs to laboriously create manual (and error-prone) segmentation rules in switches and firewalls from scratch. Our security templates take the work out of categorizing applications, or modifying the network to secure these critical applications. Applying pre-tested rule sets rapidly and accurately enables truly adaptive segmentation approaches for applications.”What this means for securityAccording to Illumio, in Windows Server areas, the new template method is especially useful, where process awareness in firewalls and network-based security technologies is poor, hampering the ability of these solutions to correctly segment and secure applications. It also takes time to fully understand how these applications operate before writing firewalls rules.To get the same type of security provided by Illumio Security Templates with a network solution demands opening a large range of ports on the servers, which can increase the attack surface of the environment. The Illumio Adaptive Security Platform (ASP)™ harnesses the specific process and path used by the server, rather than dynamic ports, and applies the exact set of segmentation rules required for complete security.Illumio Security Templates also take the guesswork out of security, since they have already been studied to be sure that they do not break applications. Security templates let organizations extend their Active Directory domains up to the public cloud without having to put security at risk.The way it works is by enabling Illumio ASP to tightly bind a segmentation policy around an application, which can then be sent quickly across a range of critical servers and applications.
