Where Ceres hides its water

Frozen water has been lurking beneath the rocky surface of the Solar System’s biggest asteroid since its birth billions of years ago.

NASA’s Dawn spacecraft began orbiting Ceres (pictured), which is also a dwarf planet, in 2015. This allowed a team led by Thomas Prettyman at the Planetary Science Institute in Tucson, Arizona, to measure hydrogen at the asteroid’s surface.

Water inside Ceres chemically alters the surface, leaving a hydrogen imprint there. The highest hydrogen concentrations appeared at mid to high latitudes. Read more

New cycling water bottle does away with the cage

Although most cyclists probably don’t give much thought to their water bottle or bottle cage, the fact is that like just about anything else, those components can be lightened and simplified. That’s just what British cycling design company Fabric has done, with its new Cageless water bottle.

The idea behind the product is pretty simple. Instead of a separate cage and bottle, Cageless consists of a BPA-free 600-mL bottle with built-in retaining clips, and a couple of plastic studs that mount on the bike’s existing cage bosses. The clips on the bottle engage those studs, so there’s no empty cage left sitting on the frame when the bottle isn’t being used. Read more

Solar Kettle boils water using the Sun’s rays

Developed by British engineer James Bentham, the Solar Kettle can boil water simply by using sunlight. The portable thermos-like product uses a special thermal technology to boil water without the need for any power input, thus making it ideal for camping, picnics and outdoor activities.

The Solar Kettle features a thermal vacuum tube which absorbs and converts the sun’s rays into heat. Two exterior reflectors open out to maximize the amount of solar energy obtained, enabling the water inside to boil without the need for any further energy supply. The kettle also comes with an built-in stand so that it can be positioned to face the sun, along with a thermometer located on the lid, which allows the user to monitor the temperature of the contents.

Ice Began to Form On Baikal Lake

In the north and east of Lake Baikal ice cover began to form. Each year this process is different. It depends on weather conditions, not only from the timing and the rate of reservoir freezing, but also from such characteristics as transparency of ice, its thickness and the type of fracture.

The main factors are air temperature, amount of snowfall, direction and wind speed. So, at -20 ° C it is formed from 4 to 5 cm of ice per day.

Baikal is usually covered with a layer of ice till January. Only the long stretch of a 10-15 km in the beginning of Angara River does not freeze. Read more
