Shining Light (Literally) On The Workings Of Cells Scientists would like to know more about how cells work. But seeing what's happening inside a cell isn't easy. It's dark in there, and even if you shine a light, many of the critical chemical reactions are invisible. Now, a team of researchers has found a way to reveal the invisible by attaching what amounts to a reflective tag to a chemical called RNA, a close relative of DNA. Molecules made of RNA have a variety of important jobs inside cells and frequently, doing those jobs requires the RNA to shuttle from one part of the cell to another. Seeing Inside Cells In the video below, researchers were studying how the addition of table sugar (sucrose) affected the growth of cells and the production of RNA. With the new ability to see RNA inside of cells by making it glow green, they learned that the addition of sucrose (the right frame in the video) dramatically increased the production of RNA – something that hadn't previously been known.

16 Fun Interactive Games About Nature Nature is one of the PBS programs that I have enjoyed for as long as I can remember. Today, I found myself looking at the Nature website again where I discovered 16 games and interactive videos about animals and other features of nature. Through the games and videos students can learn about penguins, sea turtles, and eleven other animals. Through the games students can also learn about glaciers, ocean waves, and forensics. Applications for Education Fortunately, many Nature episodes are now available to view online. Here's Nature's latest online video, An Original DUCKumentary.
Migration of Birds Northern Prairie Wildlife Research Center General Considerations While certain flight directions are consistently followed by migratory birds, it is well to remember that the term "migration route" is a generalization, a concept referring to the general movements of a species, rather than an exact course followed by individual birds or a path followed by a species characterized by specific geographic or ecological boundaries. Even the records of banded birds usually show no more than the places of banding and recovery, and the details of the route actually traversed between the two points is interpolated. In determining migration routes, one must also constantly guard against the false assumption that localities with many grounded migrants are on the main path of migration and localities where no migrants are observed are off the main path. There is also considerable variation in the routes chosen by different species. Flyways and Corridors Narrow Routes Converging Routes W.W.
Three Mistakes to Avoid When Networking - Dorie Clark by Dorie Clark | 12:00 PM February 18, 2014 We all know networking has the potential to dramatically enhance our careers; making new connections can introduce us to valuable new information, job opportunities, and more. But despite that fact, many of us are doing it wrong — and I don’t just mean the banal error of trading business cards at a corporate function and not following up properly. Many executives, even when they desperately want to cultivate a new contact, aren’t sure how to get noticed and make the right impression. I’ve certainly been there. Years ago, I was a speaker at a tech conference — as was a bestselling author. We’re all busy, but it’s hard to imagine the volume of requests that well-known leaders receive. Grant does get back to the people who write him — he even had to hire an assistant to help — but most people at the top don’t have the time management skills (or the desire) to pull that off. Misunderstanding the pecking order. Asking to receive before you give.
Blood - we can't live without it! blood; plasma; blood cells; blood types; blood transfusion; platelets; immune system; anaemia; clotting; bleeding; serum; antibodies; A; B; AB; O; antigens; rhesus; rh+; rh-; iron; periods ; Contents Blood is the fluid that keeps our bodies going. It is a transport system that carries oxygen and the essential chemicals to where they are needed in the body. It carries heat around our bodies, to keep our fingers warm and stop our brains from overheating.More than half of blood is plasma. Sometimes people need extra blood because they have lost more than the body can make in a short time or they are not making enough red blood cells (this is called anaemia (say an-ee-me-a)). Doctors can give blood from one person to another in what is called a transfusion (say trans-few-shun). The blood that someone is given is 'matched' so that it won’t be destroyed by their immune system. Type A blood can go to anyone who has type A or AB. Many people donate blood every few months. Blood is amazing.
Conflict Strategies for Nice People - Liane Davey by Liane Davey | 12:00 PM December 25, 2013 Do you value friendly relations with your colleagues? Are you proud of being a nice person who would never pick a fight? Unfortunately, you might be just as responsible for group dysfunction as your more combative team members. That’s because it’s a problem when you shy away from open, healthy conflict about the issues. Teams need conflict to function effectively. Still, I meet people every day who admit that they aren’t comfortable with conflict. Sure, pulling your punches might help you maintain your self-image as a nice person, but you do so at the cost of getting your alternative perspective on the table; at the cost of challenging faulty assumptions; and at the cost of highlighting hidden risks. To overcome these problems, we need a new definition of nice. The secret of having healthy conflict and maintaining your self-image as a nice person is all in the mindset and the delivery. Here are a few tips on improving your delivery: 1. 2. 3. 4.
