Current Science Article Stem Cell Research in the Spotlight Once Again

Recent discoveries about the role of stem cells in cancer have altered the landscape of cancer research, says Medical News Today. There is, however, a long-running philosophical rift over stem cell research at both the state and federal levels. Some groups would rather focus on adult stem cell research, avoiding the moral and ethical questions about research involving embryos. While ethical debate on human embryonic stem cells will continue, much more is occurring on the rings surrounding this bull’s-eye issue, including research in both drug development and adult stem cells.

Biologists’ understanding of new sources and uses of adult and nonembryonic stem cells is advancing rapidly. Called “niches” or “crypts,” it seems that almost anyplace one looks in the body (nose, eye, hair follicle, intestine, bone marrow, central nervous system), stem cells are being found. From such basic knowledge, it has been reported that successful animal and human therapy using patient stem cells is already occurring. As more stem cell crypts are discovered, the desire to understand how to manipulate them within the body only becomes more acute.

At the 2007 Annual Meeting of the American Association for Cancer Research, researchers presented new discoveries about stem cells in leukemia, breast and colon cancer that add to the growing evidence that perhaps cancer is, fundamentally, a stem cell problem.

Interviewed by Vision Magazine at the Stem Cells World Congress earlier this year in La Jolla, California, veterinarian and CEO of Vet-Stem, Robert Harmon, explained how his company is currently providing stem cell therapies for animals. Injected into an injury or degenerated tissue, the stem cell treatment evokes healing in unprecedented ways. As it has been since its discovery almost 400 years ago, the cell and the “vital force” that makes it the seat of biological life continues to hold attention. It is likely that there will be no end to the moral and ethical questions and investigations. Today’s new age of molecular understanding, genomics, proteomics, gene splicing and bioengineering is barely underway. It is not surprising, then, that the more we know, the more we recognize how little we understand.

The timeline of discovery has been exponential: from discovery of the DNA double helix in 1953, and the understanding of the genetic code, gene splicing and cell differentiation in the 60s, 70s and 80s, science rapidly jumped up the learning curve to the cloning of whole organisms and the discovery of embryonic stem cells less than a decade ago. The future possibilities for the application of this knowledge seem enormous.

How To Build A Greenhouse Grade 7 Science Fair Projects

A greenhouse is basically a structure that has been designed to capture and retain the heat from the sun. It is used to grow plants when the climate does not want to cooperate. Greenhouses can be used in a number of science fair projects and can be used to test concepts from a variety of fields of sciences including engineering, physics, botany and biology.

Project #1 Capturing Heat Energy

In this project the students will be designing a greenhouse that captures heat energy from multiple sources. They will be capturing heat energy from the sun and geothermal heat energy from the ground. This project will require the student to learn about heat extraction techniques related to solar energy and geothermal energy.

Sample hypotheses that can be tested with this project include:
(1) The thickness of the plastic used for enclosing the greenhouse impacts the amount of heat conservation in the greenhouse;
(2) The opaqueness of the material used for enclosing the greenhouse impacts the amount of heat conservation in the greenhouse;
(3) The depth of the insulation on the floor of the greenhouse impacts the amount of geothermal heat conservation in the greenhouse.

Project #2 Growing Radishes

In this project the student will build a greenhouse so that they can grow radishes and conduct experiments on the radish plants during times of the year that are not normally conducive to gardening. Radish projects can look at a number of things. For example, students can try to cross pollinate radishes with another root vegetable like carrots, they can attempt to grow radishes in sand or they can try to manipulate the size of the radish by exposing the plant to 20 hours of light per day.

Project #3 Engineering Greenhouses

For students that are interested in engineering, greenhouse science fair projects can be developed with an engineering focus. For example, students can try to develop a greenhouse using nothing but materials that are normally thrown out or recycled, such as cans, bottles and plastic containers. Students will not only need to design and build their greenhouse, but they will also need to test the effectiveness their greenhouse has in regards to collecting and conserving heat energy.

Project #4 Studying Solar Energy Applications

The final project option will be an application project. Students will be learning about solar energy and how to use this knowledge to harness the suns energy to heat a greenhouse. For this project students will design and build a greenhouse that maximizes the energy delivered by the sun. A good approach for this project is to see if their design can magnify solar energy within the greenhouse to make it effective in cold weather.

How is 3D printing technology used in Architecture and Medicine

D printing technology is used to manufacture prototypes, tools, and end-user parts directly from a CAD design. This printing technology offers unprecedented flexibility as it can create a part of any dimension out of any material. Some of the 3d printing materials used include metals, polymers, ceramics, composites, and many more. The 3D printing technology has complete control over material composition, surface texture, and micro-structure of the prototype. 3D printing technology also allows the user to construct prototypes using two different materials. >

Lets take a look at this amazing technology and how it has affected the field of architecture and medicine:

3D printing for Architecture

Architects know that there is nothing like a physical model of a building when it comes to displaying their work or design concept. Physical models also play an important role when it comes to explaining and convincing the customer while selling a project.

3D printers are affordable and high quality solutions for architects. Building a physical model requires great deal of expertise, precision, and time. 3D printing machines help designers focus on their building design, while the devices make 3D models of the project.

Many architects are not tech-savvy and are not used to operating complex devices. 3D printers do not require human intervention at any stage of the printing process. Architects just need to need to draw a CAD diagram of the project and instruct the 3D printer to build a 3D model. The 3D printer can print the model within a few hours, which can then be presented to the client.

3D printers are capable of producing of 3D models with accuracy and speed without compromising on the finer details of the architectural project. The price of desktop 3D printing machines is not that high and independent architects can also afford them.

3D printing for Medicine

The application of 3D printing technology can also be found in the production of medical devices. There are different 3D printing materials available that can be used to build real parts. For example, manufacturing hearing aids is a complex process because they are custom-fit devices and cannot be mass produced. 3D printing greatly helps in such matters where medical devices need to custom-fit a patient.

The future of the 3D printing technology is very bright. Market experts state that 3D printing technology will be affordable to the masses by the next decade. The prices of 3D printing devices are falling rapidly, and it is believed that the prices of 3D printers will drop by as much as 80{f1b088c654d6e092f99cfa268fb2c88d020a3f670ac79bafec5689a7dea9144e} in the next 5-10 years. It will not be a surprise to see 3D printing devices in each household just like refrigerators, washing machines, and televisions.

Technologies for Web 2.0 Websites

Technologies for Web 2.0 Websites

If someone wants to understand what is Web 2.0 design he must first be familiar with what is the meaning of Web 2.0. Web 2.0 phrase stands for the supposed second generation of the web that focuses on collaboration and sharing of information among users.

What was previously one-way highways of the old web is now replaced by a community-driven world of Web 2.0.

Some of the things related to Web 2.0 include , RSS (really simple syndication) feeds, blogs, social bookmarking websites and the like.

All of them have common factors of having interactivity and communication between the website owner and the visitors, as well as among the visitors themselves.

If you want to have a web 2.0 website, there are several skills you need to get the job done. Some need a high learning curve, meaning that they are easy to learn, while others need more effort in order to be executed properly.

I have listed down some of the skills needed in creating web 2.0 websites.

1. Need a graphics editor

– this is very important when you wish to create graphics for your website. A good graphics editor can do jobs such as simple photo editing to more complex ones such as creating gradient and reflection effects. Photoshop and GIMP are popular graphics editors used by designers. GIMP is good if you cant afford photoshop

2. HTML

– HTML is basic of web designing and it is must for any web designer needs to have. HTML is a markup language, and just like other markup languages, it tells the computer how the graphics and other elements of the page will be displayed. Basic tags are enough to let normal users get by, but knowledge of more specialized tags are needed by those who want to build better websites.

3. CSS

– is short for Cascading Style Sheets. It is also a must for a good web designer. Having a style sheet for a website makes it easier for designers to design a page by assigning values to tags such as those used in paragraphs, lists and the likes. With a style sheet, a style can be easily applied by using a variable on any part of the site.

4. Flash

– is a program used for creating animations, games and entire websites. Knowledge on how to use this is a must among web designers. While the basic commands will be enough for most users, Flash?s ActionScript gives people more control over their creations.

Less expensive mobile products
A chunk of the mobile telephone cost is the O. S. Unless the phone uses special devices and materials like camera lens similar to pro cameras or dear metals for the body, the hardware cost may not amount to a significant value since production costs are going down because of more recent technologies. The free Android OS allows the telephone costs to go down because a gigantic portion of the price isn’t applicable .

Improving Technology
Mobile systems have continuously become better and faster. The advent of this new OS will certainly allow the development of better service and features to the final user. Users should be excited with the chance of larger adventure – like the 90s when we initially began to enjoy SMS, MMS, etc .

Better Services
We’re all acquainted with the iPhone’s ability to allow 3rd party programmers to develop applications, the Android OS is not different as it also inspires other programmers to develop the technology. This allows the end users to enjoy more modern and better applications and will certainly increase the phone’s value. At the end, you’ll get more than you paid for.

Google Products
most of use Google services like Gmail and Google Documents, having an Android device will make this experience more pleasant and pleasurable. With the increasing renown of Google products you may be warranted you are getting onto a good team.

These top reasons make the Android phones a wanted product that will surely make a massive impact on the mobile industry. There are already several brilliantly designed Android phones available in the market, and these phones are getting better and cost less each quarter.

Whether you choose a traditional four-year college or an alternative program, your information technology coursework will include most of the same materials.

When you begin a computer science program, the first semester or two will be spent on the basic introductory courses. This might include computer history, basic terminology, and some other science-related course like calculus and chemistry. This is the point that students often decide which direction they want to take their computer science degree, which could range from programming to networking to computer repair and building. Programming is probably the most popular choice these days, though.

Once you have finished the basic courses and decide on the area you want to specialize in, you can start taking more specific courses. If you want to go into programming, for example, you can start taking fundamental courses in BASIC, FORTRAN and COBOL before more advanced courses on topics such as programming languages like C++ and PASCAL. Or, if you want to go into networking, you will begin taking courses that concentrate on networking systems like Novell and Microsoft Networks.

In most cases, a bachelors degree in computer science or information will involve some sort of final project. The computer and information technology program curriculum may vary from one school to the next, however, and it will also vary greatly depending on the degree you are going after. If you are getting a certificate or an associates degree, you might just focus on one very specific area or get a more basic overview of things. And, if you are getting a masters degree, the learning will be much more in-depth for your specific area of specialization. You can learn more about the program curriculum at various schools by visiting their web sites or speaking to a counselor there.

Technology For Women And What It Can Offer Us

The colour pink is often associated with women as more often than not, women look good in pink. Women who have great fashion senses are often eye catching and you may well have noticed that a woman’s fashion sense has begun to extend towards the gadgets that they carry. The rise of feminine technology has been growing steadily and is about to hit a crest. When you say feminine technology what is the first thing that comes to your mind? Pink gadgets!

Since the colour pink has long been associated with women, it doesn’t come as a surprise to see pink mobile phones, pink digital cameras, and pink laptops, among others that can be considered as part of feminine technology. Pink is a dainty colour, eye-candy if you like. Given the choice, fashionable women tend to want to carry trendy gadgets to veer away from the more macho-looking laptops or cellular phones. Women now find it tempting to have a pink gadget, like a pink laptop, to showcase their love for beauty. Most women are aware that most men find a woman to be more feminine if they are wearing something pink, and i have to admit there is something appealing about a confident women seen doing some work on a pink feminine laptop or making a business call with a pink mobile phone.

Technology need not be boring and with the advent of feminine technology, pink and all the other girly colours have become the in thing. Pink may be a favourite, but red is also becoming popular, as well as lavender or pastel colours. You will even see laptops that have designs on it; often utilising many different shades of pink or other feminine colours.

Wouldn’t it be great to take snapshots using your pink digital camera? You will now find digital cameras, mobile phones, and laptops in various shades of pink and as well as other girly colours so finding one that suits your personality is no longer the challenge that it once was. However do not, for a second, think that gadgets with a touch of femininity are lacking in the features or power department. A lot of popular brands now carry fashionable designs but still with the exact same technology and features as more masculine looking gadgets.

This is true especially for laptops. Pink laptops may look dainty and beautiful yet you can be sure that you can still surf the net with ease and do some office or school work simultaneously without having your workflow slowed by unresponsive technology. It is just as important to take note that when you shop for a gadget that will showcase your feminine side, make sure that you check the features as well as the prices first before settling with one particular unit.

So when you talk of feminine technology, it is not only about trends and beauty, functionality is also a must have and one that manufacturers are increasingly more aware of.
