Mice can 'warn' sons, grandsons of dangers via sperm › News in Science (ABC Science) News in Science Monday, 2 December 2013 ABC Epigenetic changes Lab mice trained to fear a particular smell can transfer the impulse to their unborn sons and grandsons through a mechanism in their sperm, a study reveals. The research claims to provide evidence for the concept of animals "inheriting" a memory of their ancestors' traumas, and responding as if they had lived the events themselves. It is the latest find in the study of epigenetics, in which environmental factors are said to cause genes to start behaving differently without any change to their underlying DNA encoding. "Knowing how ancestral experiences influence descendant generations will allow us to understand more about the development of neuropsychiatric disorders that have a transgenerational basis," says study co-author Brian Dias of the Emory University School of Medicine in Atlanta, Georgia.
Information Technology Infrastructure Library ITIL (formerly known as the Information Technology Infrastructure Library) is a set of practices for IT service management (ITSM) that focuses on aligning IT services with the needs of business. In its current form (known as ITIL 2011 edition), ITIL is published as a series of five core volumes, each of which covers a different ITSM lifecycle stage. Although ITIL underpins ISO/IEC 20000 (previously BS15000), the International Service Management Standard for IT service management, the two frameworks do have some differences. ITIL describes processes, procedures, tasks, and checklists which are not organization-specific, but can be applied by an organization for establishing integration with the organization's strategy, delivering value, and maintaining a minimum level of competency.
6 Things The Most Productive People Do Every Day Ever feel like you’re just not getting enough done? Know how many days per week you’re actually productive? About 3: Wearable Neurocam The "neurocam" is a wearable device that can detect emotions via brainwaves, and automatically records "scenes" based on the wearer's interest level. From KurzweilAI: The algorithm is based on measures of “interest” and “like” developed by Professor Mitsukura and the neurowear team.The users interests are quantified on a range of 0 to 100. The camera automatically records five-second clips of scenes when the interest value exceeds 60, with timestamp and location, and can be replayed later and shared socially on Facebook.
Scrum (software development) Scrum is an iterative and incremental agile software development framework for managing product development. It defines "a flexible, holistic product development strategy where a development team works as a unit to reach a common goal", challenges assumptions of the "traditional, sequential approach" to product development, and enables teams to self-organize by encouraging physical co-location or close online collaboration of all team members, as well as daily face-to-face communication among all team members and disciplines in the project. A key principle of Scrum is its recognition that during a project the customers can change their minds about what they want and need (often called "requirements churn"), and that unpredicted challenges cannot be easily addressed in a traditional predictive or planned manner. Later, Schwaber with others founded the Scrum Alliance and created the Certified Scrum Master programs and its derivatives.
Monotasking Is The New Multitasking We all know multitasking is inefficient. A classic 2007 study of Microsoft workers found that when they responded to email or instant messaging alerts, it took them, on average, nearly 10 minutes to deal with their inboxes or messages, and another 10-15 minutes to really get back into their original tasks. That means that a mere three distractions per hour can preclude you from getting anything else done. Then there’s the relationship “inefficiency” that comes from multitasking. You can spend hours rebuilding the good will torched by a single glance at your phone during an inopportune time. We know this, yet we keep doing it.
Injectable, Cellular-Scale Optoelectronics with Applications for Wireless Optogenetics Successful integration of advanced semiconductor devices with biological systems will accelerate basic scientific discoveries and their translation into clinical technologies. In neuroscience generally, and in optogenetics in particular, the ability to insert light sources, detectors, sensors, and other components into precise locations of the deep brain yields versatile and important capabilities. Here, we introduce an injectable class of cellular-scale optoelectronics that offers such features, with examples of unmatched operational modes in optogenetics, including completely wireless and programmed complex behavioral control over freely moving animals. The ability of these ultrathin, mechanically compliant, biocompatible devices to afford minimally invasive operation in the soft tissues of the mammalian brain foreshadow applications in other organ systems, with potential for broad utility in biomedical science and engineering.
Time Management Tips: How to Find the Right Mindset to Succeed With Time Management For the past several years I have worked with time management techniques such as lists, prioritization, planning and so on. But it wasn’t until I adopted a Quadrant 2 mindset that I really started seeing results. 50+ Tools for Differentiating Instruction Through Social Media Imagine a world where resources were limited to what was found in the classroom or the school closet known as the "Curriculum Materials Room." Picture a world where students wrote letters with pen and paper to communicate with other students and adults outside of the building. Due to postage costs, the teacher either sent the letters in bulk or paid for stamps out of his or her own pocket.
Non-Invasive Brain-to-Brain Interface (BBI): Establishing Functional Links between Two Brains Transcranial focused ultrasound (FUS) is capable of modulating the neural activity of specific brain regions, with a potential role as a non-invasive computer-to-brain interface (CBI). In conjunction with the use of brain-to-computer interface (BCI) techniques that translate brain function to generate computer commands, we investigated the feasibility of using the FUS-based CBI to non-invasively establish a functional link between the brains of different species (i.e. human and Sprague-Dawley rat), thus creating a brain-to-brain interface (BBI). The implementation was aimed to non-invasively translate the human volunteer’s intention to stimulate a rat’s brain motor area that is responsible for the tail movement. The volunteer initiated the intention by looking at a strobe light flicker on a computer display, and the degree of synchronization in the electroencephalographic steady-state-visual-evoked-potentials (SSVEP) with respect to the strobe frequency was analyzed using a computer.
DevOps DevOps (a portmanteau of development and operations) is a software development method that stresses communication, collaboration and integration between software developers and information technology (IT) operations professionals. DevOps is a response to the interdependence of software development and IT operations. It aims to help an organization rapidly produce software products and services. Companies with very frequent releases may require a DevOps awareness or orientation program. GTD Cheatsheet – An Intro on the GTD system The system created by David Allen in his popular book Getting Things Done focuses on freeing up your mind’s RAM (or resources). The GTD system simply takes all or our mental and physical “stuff” in our lives and organizes it into a system where we can easily: 1) Act on it or
Body swapping: the science behind the switch Next year sees the release of the Ben Kingsley/Ryan Reynolds film Selfless, where a wealthy elderly dying man transfers his consciousness from his diseased and ravaged body into a younger, sexier one. This is quite a familiar trope in fiction, the body swap, where a character finds his or herself inhabiting a completely different body. Alternatively, there’s David Brin’s Kiln People (one of my favourite ever sci-fi books) which invents a whole new field of science to explain it. In this world the mind can be copied and transferred into duplicates, but never swapped between humans.
