Scientists Produce Electricity From Tears

A protein in tears can actually generate electricity.

Many scientists are finding ways to produce electricity from unlikely sources. Recently, a team of Irish researchers was able to squeeze out electricity from tears. So does this mean that if your cell phone battery goes dead, you just need to cry a little bit more?

Well apparently, the scientists from the Bernal Institute at the University of Limerick discovered that it is possible to generate current from tears, or specifically, from a type of protein present in tears.

Tears have been found to generate an electrical current.

They produced electricity by applying pressure, dubbed as piezoelectricity, to the lysozyme protein, which is found in tears and in egg whites. Aside from these sources, this type of protein is also found in milk and saliva, as reported in the scientific journal, Applied Physics Letters.

Aimee Stapleton, the lead author of the study, explained:

“While piezoelectricity is used all around us, the capacity to generate electricity from this particular protein had not been explored. The extent of the piezoelectricity in lysozyme crystals is significant.”

She added:

“It is of the same order of magnitude found in quartz. However, because it is a biological material, it is non-toxic so it could have many innovative applications such as electroactive anti-microbial coatings for medical implants.”

Lysozyme is an enzyme that aids in the breakdown of bacterial cell walls.

However, when converted into their crystallized form, it can be controlled to generate an electrical charge.

The researchers hope that in the future, their discovery could pave the way to the development of flexible and energy-harvesting electronics. For instance, future scientists could develop new kinds of implants that release drugs in the body, which are powered by sensors that detect the lysozymes beneath the skin.

This discovery could shed the light on the biological applications of piezoelectricity.

The scientists also hope that others may work on other scientific studies based on what they have found regarding lysozymes and how these can produce electrical currents.

New Study Says Tone of Voice Can Help Identify Cheaters

The key, indeed, is listening.

Love is a beautiful thing, but it could also be ugly, painful, and tragic at times. Hearts can break and relationships can end with just one mistake. In most cases, that mistake is cheating. And it's not always easy to tell if someone is being unfaithful. Sometimes, the truth just surprises and crushes you.

But there's a new study that might just help cautious lovers tell if their significant other had cheated on them. According to the research titled "Your Cheatin’ Voice Will Tell On You: Detection of Past Infidelity from Voice" published in Evolutionary Psychology, listening to the tone of your partner's voice can be more revealing than you initially thought.

Susan Hughes of Albright College and Marissa Harrison of Penn State Harrisburg co-authored the study.

Forget Apple and Samsung Watches, LooK IoT Standalone Smartwatch Is The Next Big Thing

The awesome features found in this smartwatch could give Apple and Samsung a run for their money.

Smartwatches are becoming more sophisticated as different mobile phone companies compete in the arena. Every year or so, new models of wearable devices are introduced to consumers, enticing them with several new features. A few have started to put an end to phone tethering, which means the watch can be used without being paired to a mobile phone.

One of the smartwatches that offer a ton of awesome features and don't need to be tethered to a phone to make calls or send SMS is LooK Watch. And judging by the features of this wearable device, it could give Samsung and Apple Watches a run for their money.

LooK Watch is considered the first standalone Internet of Things (IoT) smartwatch.

Tropical Forests Are Now Emitting More Carbon Than Oxygen, New Study Says

We should all be concerned.

Years of abuse and misuse of the Earth's forests have resulted in the tropics now emitting more carbon than oxygen, says a new study. This is alarming because tropical forests have always been considered a vital carbon “sink” that consumes carbon from the atmosphere and turns and releases it into oxygen. Today, however, tropical forests already emit almost twice as much carbon as they consume. Scientists say stopping deforestation and degradation in the tropics could help reverse this trend.

In a paper published in the journal Science, scientists from Boston University and the Woods Hole Research Center said there is a limited window of opportunity to reverse the troublesome trend, and that's by restoring forested areas.

The researchers used a new method to assess carbon density in areas affected by deforestation and degradation.
