Matter & Energy

The increase in need for, and the implementation of renewable or clean energy questions the premise of its safety and reliability because it brings about the possibility of it being threatened by hackers through theft or cyberattacks. The magnitude of real-time data and the distributed generation of energy make for easy gateways.

Hydrogen derived from water and exploited for its potentially huge energy payload is a substance of interest for those researching post-oil fuels and their uses. Some researchers and inventors conclude that hydrogen is the clean, green solution to humanity’s consistent need for power. The last few years alone have seen a revolution in hydrogen-purification methods.

The batteries that power our smartphones, tablets and other similar electronics are a crucial factor that affects how we use them on a daily basis. Despite advances in their technology, they may still discharge at a faster rate than we might like, and interrupt our screen-time when it’s time to recharge them.

Lately, a lot of effort has been dedicated to researching new approaches to harvest green energy, from environmental resources. Green, or renewable energy, is collected from renewable resources, such as wind, geothermal heat, sunlight, waves and river motion. Furthermore, human body motion is also being considered as a potentially very rich source of energy.

We are in need of novel new fuel sources for the future, with one potential solution being the possibility of converting fatty acids to hydrocarbons using an algal enzyme which is activated by light. The ability to scale this recently discovered reaction to an industrial level could well provide an environmentally friendly new source of hydrocarbon energy.

Storing natural energy sources like wind and solar energy is highly unpredictable, thus hastening the need to resort to alternate means. While some countries have taken to stockpiling hydroelectricity, other nations face challenges due to reasons like water scarcity or poor accessibility. Meanwhile, the daily requirements for energy via televisions, air conditioners, water heaters and so on, continue to escalate among both our homes and places of work.

Cells are able to transmit and process information by using molecular machines designed by evolution. These biochemical machines, usually proteins, change their structure and function in predictable ways based on input from the environment. These components of the cell can be organized into cascades, or branching chain reactions, in which the changes in one component are transmitted to a large number of components downstream.

In the scenic mountain ranges of Rjukan in Norway, tourists can go and see the evidence of work on using hydrogen as a fuel source. This location contains waterfalls that were harnessed for hydroelectric power in the 1920s. The energy generated from this plant would be used to split water into hydrogen and water using electricity through a process known as electrolysis, in an adjoining factory.

Inspired by the high temperatures of the last few years, engineers from Stanford University have created a plastic-based material which can keep pour bodies cool. The idea is that it could be incorporated into clothing items, to cool the wearer’s body far more efficiently than current natural or synthetic fabrics.

The International Energy Agency estimate that around the world, 1.8 billion people live without electricity. In Africa, this is a particular issue. In an interview with CNBC, Ponmile Osibo from the African Private Equity and Venture Capital Association said: “The situation is Arica at the moment is quite significant, over 40 percent of the population does not have direct access to energy.”

For years, physicists have been trying to track down an elusive particle which, although predicted by the Standard Model of particle physics, has evaded detection until now. This week, the LHCb experiment at CERN’s Large Hadron Collider has definitively detected the presence of this particle, known as Xi CC ++.

We all love smart technologies. Smart phones, smart cars, smart houses, and so on. I have a device in my pocket that can relay my location by GPS, calculate the distance to my destination, count the number of steps it takes me to get there and displays the number of calories I burned; all of this while I stream cat videos from the internet. I can even control my smart house remotely from my phone, or have the doors to my smart car automatically unlock as I approach. It is glorious.
