    Factors To Consider When Buying Sports Headphones

    The proliferation of various brands and models of sports headphones has made finding the right one a daunting task. In general, the key to finding the right model is dependent on the level of activity you are engaged in. This will make the process of choosing much easier.

    In choosing sports headphones for running, make sure they pass through your ears or behind your neck. The main concern with these types of earbud headphones is that they tend to fall when you run. This type of headphones can be used for jogging but not for serious running. Another consideration when choosing headphones for running is its weight. Make sure it’s not too heavy because it can affect your running.

    Another important consideration in choosing sports headphones is the ability to handle sweat. If you exercise regularly, make sure this unit is able to handle a lot of sweat.

    If the cable can cause too much discomfort and interference in your activities, you can consider Bluetooth or a wireless unit. Running too much or exercising can cause the cable to become entangled. Wireless or Bluetooth headphones may be more expensive but they may be a valuable investment.

    Listening to music while exercising is always a pleasant experience. However, the headphone that came with your MP3 player may not be enough as they are just designed for walking or sitting down.

    If you like doing he treadmill often, consider buying models with clips. Likewise, make sure that it is sweat proof if you are fond of doing heavy workouts. A good model to consider is the neckband headphone.

    Headphones for swimming come in several sizes and varieties so finding the right one for you will be no problem. If the regular waterproof headphone is insufficient, consider buying swimming headphones. This is the …

    Engineering Partially Synthetic Stem Cells

    The stem cell debate rages on. Many states and countries outright ban stem cell research because of how stem cells are harvested. What if we were able to engineer our own (partially) synthetic cells for research purposes? Surely this would alleviate ethical concerns surrounding stem cell research. A Madison based company called Cellular Dynamics are pushing the boundaries of induced pluripotent stem cell (iPS) research to the limits to bring them into the limelight and dissolving the controversy that springs forth from concerns related to harvesting these types of cells from a human foetus. Sounds like an easy fix? Well, to some extent yes.

    Induced pluripotent stem cells start out as cells harvested from adults. The cells are then introduced to certain genes that are generally only found active in embryos. These cells can do exactly the same things as what a regular stem cell that has been harvest from an evolving human foetus. The beauty of iPS cells is that they are not only useful for treating disease or injury but are also excellent test cells for tracking the progress of a disease on a molecular level. At the moment, Cellular Dynamics are creating iPS cells that are transformed into heart muscle cells to pharmaceutical companies that wish to have an untainted test bed to test the reaction of drugs to human body tissue.

    Cellular Dynamics are currently developing brain and liver cells to enable a greater range of cells to test drugs on. There is no telling how far the technology can progress as a means of testing and treatment on a wider scale however. These cells can be developed from people that come from a range of cultural and ethnic backgrounds as well – this gives researchers the opportunity to test how cells react depending on the …
