Internal bleeding should be taken seriously, and not just because it could indicate signs of severe trauma. This form of hemorrhage, which occurs in blood vessels far away from the skin (e.g., between internal organs) can deprive tissues affected of nutrients and oxygen, thus, increasing the risk of adverse events such as ischemia or necrosis.

Many of us may be considering adopting or investing in the emerging low-carbon solutions in the market, so as to save both money and the environment. However, we may also be waiting for that perfect piece of technology or innovation that is definitely going to giving us our money's worth.

Inorganic semiconductors are potentially useful in many areas of electronics and industry. Unfortunately, they tend to be disadvantaged in their reduced flexibility or plasticity. Therefore, they can snap or break apart under the forces necessary to form or bend them.

Storm Emma, which occurred in early 2018 in the UK, may have stressed the importance of heat conservation for the many people affected by it.

Modern dwellings can be insulated by incorporating thin sheets of aerogel or Styrofoam into building shells during construction. However, these materials are synthetic and can represent environmental damage in their manufacture or disposal.

If scientists from the future were to be asked about the significant discoveries of the 2010s, the term 'time crystal' would probably be at the top of that list.

Time crystals are solid compounds in which some atoms have been observed to "tick" regularly when exposed to electromagnetic fields.

The definition may sound a little underwhelming. However, it is the first example of atoms behaving in this manner.

In addition, time crystals may have many important roles in the electronics and engineering of the future.

A team of Scottish scientists has developed a type of laser that is thin enough to be integrated into contact lenses.

However, those hoping to emulate their favorite Marvel character with super-ocular powers could be disappointed! The type of light the putative 'laser contacts' was designed to emit is more likely to turn someone into an authorized individual with easily-scanned credentials rather than an artificial X-man.

Coloring one's hair is a regular personal care routine for many people. It is often used as an avenue to self-expression or as a way to stand out from the crowd. However, the actual process of coloring is not usually a favorite chore.

Most commercial hair dyes have the disadvantage of being potentially irritating, damaging to property or surfaces and smelling to a horrific degree. Even newer formulations contain chemicals that could be toxic to the environment at their disposal.

Up to 70% of the electrical energy generated per year in the United States is wasted. This could be owed to the fact that the energy comes in the form of heat, which is then allowed to escape from its sources such as electronics, vehicles or industrial appliances.

For example, you may find that your phone heats up more when gaming or running heavy-load apps. This phenomenon is known as waste heat. New inventions or developments that could re-purpose more waste heat would be welcome, as doing so could cut down on overall energy use.

Sweat is a surprisingly rich seam of biological information that can help track prevalent health metrics such as blood glucose and stress levels. It can be used to detect blood alcohol levels too.

However, getting samples of the fluid is not as easy as it sounds. Typically, people don't have as much conscious control over supplying a sweat sample as they might have with some other bodily fluids.

Health tracking through sweat collection and analysis could be more convenient and amenable to everyday life than traditional methods.

Platinum is a mid-table, stable, white metal prized for its use in jewelry and electronics. The metal has excellent conductive properties in addition to its good looks.

However, the metal does not have other beneficial properties, thus limiting its use and value. For example, no form of platinum has ever been magnetic...that is, until now.

Everyday appliances, especially cell phones, tend to slip and fall into dangerously sticky and disgusting places, quite often — think washrooms, the kitchen, or public places!

Stats reveal that, on average, a large percentage of smartphone owners damage their devices by dropping it. An interesting observation also found that 28% drop their mobiles into a liquid (usually water), and about 8% spill food/drink on their phones.

In all fairness, most electronics such as cameras, lenses, and laptops, are susceptible to irreparable damage.

People who have taken to the idea of alternative energy and are considering using it as a power source may be interested in this piece of news:

Tesla, the popular electric car manufacturer, has been designing solar roof tiles, and they are now available to consumers in California! These branded panels, when installed, absorb power from the sun and convert it into electricity for homes.

Long-term recovery from conditions involving the abuse of substances, such as alcohol, can be an incredibly difficult thing to achieve. Many people who benefit from it could be aided by devices or techniques that help track their abstinence (or lack thereof, occasionally) over time.

Patients with certain conditions undergo regular diagnostic procedures such as electroencephalograms (EEGs) in order to track their health. Over time, the equipment used to deliver such readings has evolved to enhance comfort and convenience. These advancements have been made possible by chemical engineering and materials sciences.

Carbon nanotubes are one of the world's newest supermaterials. They can be used in electronics, medical research, material science, and even water purification.

“We were inspired both by science fiction and science fact – seeing dinosaurs disappear and reappear under an infrared camera in ‘Jurassic World’ and seeing squid filmed underwater do similar things.”
- Alon Gorodetsky, professor at UCI

Cephalopods, the class of marine animals including squids, octopuses and cuttefish, have a specialized mechanism of escaping from their prey or while signaling — camouflage.

Biological and chemical nanoengineers are faced with the problem of getting molecules to take the shapes they want towards certain applications.

For example, tissue engineering may require molecular 'scaffolds' to deliver and build matrices of the new cells needed to replace those lost in wounds or other anomalies. However, it is difficult to get synthetic large-scale structures to stay in one piece, in vitro or in vivo. This instability is due to the difficulty in finding chemical formulas that will result in reliable, robust lattice structures.

In the coming years, with groundbreaking research in the interdisciplinary areas of science, medicine, healthcare and technology, it is possible that chemical batteries we are familiar with will be completely replaced.

Reasons to seek alternatives include bulkiness, instability in extremes of temperature, toxicity of chemicals and low sustenance.

The increased 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 being threatened by hackers by way of theft or cyberattacks. The magnitude of real-time data and the distributed generation of energy make for easy gateways. Take charging an electric car, for example — a group of such vehicles are ultimately connected to a larger power unit, which can, if jeopardized, compromise the grid of an entire city.

What if we could generate all the energy required to power the whole of civilization, just using wind turbines? It might sound far-fetched but new research published this week has suggested that this scenario is not entirely unrealistic.

A new location for wind farms

It would however, require some significant changes to the location of wind farms – placing these far out in deep water areas of our oceans, as opposed to on land or relatively near to the shore.
