Nuclear power – how it works

In a nuclear power plant, energy is derived from splitting atomic nuclei. The process is called fission, and it heats water to form steam. The steam powers a turbine, which in turn powers a generator that generates electricity.

Fission takes place in the reactor. During the process, atomic nuclei are split by bombarding them with neutrons. When an atomic nucleus is split, it emits new neutrons that can split new atomic nuclei, creating a chain reaction. A nuclear power plant typically uses uranium-235, a special isotope of the element uranium, as fuel. In order to control the process, various types of control rod stems are used to absorb the discharged neutrons, reducing the fission rate or stopping it entirely.

There are several different types of nuclear reactors, the most common of which are pressurised water reactors and boiling water reactors.

How climate is changing

Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner.

Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.

Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.

According to the IPCC, the extent of climate change effects on individual regions will vary over time and with the ability of different societal and environmental systems to mitigate or adapt to change.

The IPCC predicts that increases in global mean temperature of less than 1.8 to 5.4 degrees Fahrenheit (1 to 3 degrees Celsius) above 1990 levels will produce beneficial impacts in some regions and harmful ones in others. Net annual costs will increase over time as global temperatures increase.

"Taken as a whole," the IPCC states, "the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time."

Ginger: Health benefits and dietary tips

Ginger is a popular ingredient in cooking, and especially in Asian and Indian cuisine. It has also been used for thousands of years for medicinal purposes.
Possible health benefits include relieving nausea, loss of appetite, motion sickness, and pain.

The root or underground stem (rhizome) of the ginger plant can be consumed fresh, powdered, dried as a spice, in oil form, or as juice. Ginger is part of the Zingiberaceae family, alongside cardamom and turmeric. It is commonly produced in India, Jamaica, Fiji, Indonesia, and Australia.

It is available fresh and dried, as ginger extract and ginger oil, and in tinctures, capsules, and lozenges. Foods that contain ginger include gingerbread, cookies, ginger snaps, ginger ale, and a wide variety of savory recipes.

12 Tips to Keep Skin Soft and Glowing In Winter

Winter weather is not fun for skin. Cold weather and low humidity levels result in dry air, which then steals moisture away from the skin every second of every day. Without immediate care, dry skin can lead to cracking and bleeding, and harsh winter wind makes the problem worse. Indoor heat further robs the air of moisture, as do hot showers or baths and harsh cleansers.

Additional moisture helps, but you need to do more to actually counteract these effects and keep skin looking youthful and smooth. To reduce chapping, redness, itching, and keep skin more healthy and comfortable this season, try these tips.

THE RISKS OF LIP TATTOOS: WHAT YOU SHOULD KNOW

Tattoos have been a popular form of body art for many years. In fact, Statistic Brain reports that 45 million Americans have at least one tattoo somewhere on their body.

The latest tattoo trend to explode in popularity is lip tattoos. Although any tattoo procedure can be risky, if you’re thinking about getting one on or inside of your lip, you might want to first investigate the specific risks of lip tattoos before going under the needle.

Here are some important things to keep in mind when considering inner-lip and lip-liner tattoos.

BEST DSLR CAMERAS OF 2018

Digital SLR cameras are among the cream of the crop. Image and video quality are outstanding, features continue to advance year after year, and they have the most varied selection of lenses. But the market is large, ranging from full frame (professional cameras with massive sensors) to a host of mid-range and budget models. Below we break down the top DSLRs on the market in 2018, including leading options from brands like Canon, Nikon, Pentax, and Sony.

1. Nikon D850

Category: Full frame
Sensor size: 858 sq. mm
Megapixels: 45.7
What we like: Exceptional image and video quality.
What we don’t: Limited availability.
Lenses: 10 Great Nikon FX (Full Frame) Lenses

For years, Canon led in full-frame DSLR innovation while Nikon laid in wait. Well, the wait was worth it. The D850 is an absolute powerhouse DSLR and one of the top cameras on the market of any type. Compared to the Canon 5D Mark IV below, the D850 wins out in most categories that matter: it has 45.7 megapixels of resolution vs. 30.4 on the 5D Mark IV, superior autofocus, faster buffering speeds, a higher resolution LCD screen, and significantly longer battery life. The 5D Mark IV weighs a little less and has built-in GPS, but given that both cameras are similar in price, we favor the D850 in a big way.

2. Canon EOS 5D Mark IV

Category: Full frame
Sensor size: 864 sq. mm
Megapixels: 30.4
What we like: 4K video and a host of other modern features. 
What we don’t: The D850 above is so impressive that it overshadows the 5D Mark IV. 
Lenses: 10 Great Canon EF (Full Frame) Lenses

Canon’s 5D Mark IV was at the top of this list for much of last year, until the release of the Nikon D850 that is. When you put the two head to head, it’s flat out hard to argue that the Canon is better. It has lower resolution, inferior autofocus (although it does have dual pixel), and doesn’t offer much in the way of additional features or functionality. Having said that, the 5D Mark IV is a quality camera and all that most Canon professionals and enthusiasts will need. If you already own a bunch of L series glass, sticking with Canon is a fine choice. And as we’ve come to expect, this is an arms race and Canon likely will respond in kind.

3. Canon EOS 6D Mark II

Category: Full frame
Sensor size: 861 sq. mm
Megapixels: 26.2
What we like: One of the best values on this list.
What we don’t: Video shooters may want to spend up for the 5D series.
Lenses: 10 Great Canon EF (Full Frame) Lenses

Here’s a fun one: if Canon’s 5D series above is too rich for your blood, the 6D series offers a reasonable entry point into the full-frame camera market. Released in 2017, the 6D Mark II offers notable improvements over its predecessor while still staying well below the $2,000 price threshold. Compared to the older model, you get a bump in resolution to 26.2 megapixels, a more advanced autofocus system, faster shooting, and touchscreen functionality on the rear LCD. All are solid improvements and the 6D Mark II is a really nice value, particularly for still photography (the 5D series is much better for video).

4. Nikon D750

Category: Full frame
Sensor size: 861 sq. mm
Megapixels: 24.3
What we like: A Nikon full-frame camera for less than $1,800.
What we don’t: With a 2014 release date, the D750 is getting a little long in the tooth. Lenses: Best Lenses for Nikon D750

Nikon didn’t exactly get off to a strong start with the sensor issues of the old D610 and D600, but they got it right with the D750. In many ways, the D750 mirrors the image quality and functionality of the D810 only with fewer megapixels. You get the same EXPEED 4 image processor, image sensor dimensions, and 1080p video speeds. The D750 has an optical low pass filter (the D810 does not), but it also boasts a faster frame rate at 6 fps. Of course, the resolution is lower at 24.3 megapixels, but this is more than enough for many photographers and uses.

5. Pentax K-1

Category: Full frame
Sensor size: 864 sq. mm
Megapixels: 36.4
What we like: Impressive resolution and weather sealing for the price.
What we don’t: Limited lens options and subpar video.

For landscape and still photographers looking for a cheaper alternative to full-frame DSLRs from Canon and Nikon, the K-1 comes with few compromises. Ricoh-owned Pentax has long been known for its crop-frame cameras, which are strong on paper and competitively priced, and the trend continues with the full-frame K-1. Released last year, this DSLR has 36.4 megapixels of resolution (just a hair shy of the Nikon D810), built-in image stabilization, and a sturdy aluminum alloy body that is sealed as well as any model on this list.
