Extroverts and neurotics tend to use Facebook and WhatsApp more

by , in
From a recent study:

20% of smartphone behavior can be accounted for by WhatsApp usage, and females use it 13 minutes longer than males.

Extroversion is of high importance in understanding WhatsApp usage, extroverts use it longer vs introverts.

High neurotics tend to use Facebook more as it facilitates communication without face-to-face interaction.

On the other hand, conscientiousness is inversely correlated with WhatsApp usage. Conscientious humans handle their digital consumption better and are less prone to Internet addiction.

Are you conscientious? Conscientious humans can be described as punctual, and diligently follow their daily routines.

New Solid-State Batteries From Samsung/MIT Could "Last A Lifetime"

by , in
Batteries. We need them for almost everything we use. They're in our laptops, our smartphones, our video game controllers, our remotes, and anything we use that is now wireless. But the one thing wrong with batteries in today's world is that they are finite. Eventually, they will run out of power and there's not a whole lot we can do about that. Or is there?

Researchers have recently developed a new material for a basic battery component that, according to them, will allow almost any battery indefinite power storage. This new material, known as a solid electrolyte, could increase battery life as well as battery storage capacity and safety as liquid electrolytes are the leading cause of battery fires.

The standard lithium-ion batteries that we use today use a liquid electrolyte. This liquid electrolyte is an organic solvent that has been known to overheat and cause fires in things like cars, commercial airliners and even smartphones. With a solid electrolyte, there is absolutely no safety problem whatsoever.

According to Gerbrand Ceder, a professor of materials science and engineering at MIT and one of the main researchers on the project, "You could throw it against the wall, drive a nail through it - there's nothing there to burn." In addition to that, a solid-state electrolyte will have virtually no degradation, which means that such batteries could last through "hundreds of thousands of cycles," Ceder continued.

Organic electrolytes also have limited electrochemical stability, which means that they lose their ability to produce an electrical charge over time. In addition to MIT, scientists from the Samsung Advanced Institute of Technology, the University of California at San Diego and the University of Maryland also conducted research on the project.


The findings were published in the peer-reviewed journal Nature Materials and the researchers described the solid-state electrolytes as an improvement over the current lithium-ion batteries we are using today. Electrolytes are one of three main components in a battery along with anode and cathode terminals.

The electrolyte component of the battery separates the battery's positive cathode and negative anode terminals while allowing the flow of ions between terminals. A chemical reaction then takes place between the two terminals, producing an electric current.

Previous problems with solid electrolytes are that they were incapable of conducting ions fast enough to be efficient energy, producers. The team of researchers from MIT and Samsung say that they have overcome that problem. Another advantage of a solid-state lithium-ion battery is that it can perform under very cold temperatures with Ceder calling this breakthrough "a real game-changer" that creates an "almost perfect battery".

Acer's Aspire Z3-710 All-In-One Gets Windows 10

by , in
On Monday, Acer announced that its 23.8-inch Aspire Z3-710 Series of all-in-one desktop PCs are saving you some time by shipping with Windows 10. so you won't have to do the free upgrade from Windows 8.1.

The Z3-710-UR55 at $750 and Z3-710-UR54 at $900 will be the two models that ship with Windows 10. The Z3-710-UR55 comes with an Intell Core i3-4170T dual-core processor clocked at 3.2GHz with 3MB of cache, 6GB of DDR3L RAM, 1TB hard drive, DVD writer, 802.11ac Wi-Fi, Bluetooth 4.0 + LE, 1080p webcam, three USB 2.0 ports, two USB 3.0 ports, GbE LAN, and stereo speakers.

The Z3-710-UR53 has a Core i5-4590T quad-core processor clocked at 2GHz with 6MB of cache and 8GB of RAM. If you're just using general purpose computing chores, it might not be worth the additional $150 as you only get 2GB of additional RAM. Even with the processor being an upgrade in cores and cache, it really is a downgrade in clock speed.

Looking for a Quote on a Desktop Rental for Your Business Event? Rentacomputer has a full range of Desktop Rentals for your event! Our short-term rentals are available in over 1,500 cities nationwide!

Acer says that both systems come with a slim 1.4-inch chassis with a display that can tilt from 5 to 25 degrees using only two fingers. If these don't sound as appealing to you, Acer still offers the Z3-710-UR59, which is a Windows 8.1 model, only at $700. It has an Intel Pentium G3260T dual-core clocked at 2.9GHz, 4GB of RAM, and 1TB HDD. All of the systems sound pretty cool and the fact that they are All-in-Ones is a definite bonus. You just need to find which one bests suits your needs.

"Bio-detection" dogs in trial to be used for prostate cancer sniffing

by , in
Many urologists agree that the PSA test for detecting prostate cancer is often unreliable, but it remains widely used because there are no other relatively inexpensive tests. Researchers in Britain say this method may soon be replaced with dogs trained to sniff out the type of cancer that, according to the American Cancer Society, affects one in every 7 men. VOA’s George Putic reports:



It takes 6 months to train a dog to detect prostate cancer. According to the report, trained dogs can detect prostate tumors in urine in 93 percent of cases.

"These dogs have the ability to screen hundreds of samples in a day; it's something they find very easy, they enjoy their work. To them it's a hunt game - they find the cancer."

The alternative, "electronic nose" sensitivity is well below the one of a dog. A dog can find 1 part per trillion. An electronic nose is unable to find anything below 1 per million.

All about hair loss (alopecia) - Deutsche Welle expert interview

by , in
Dr. Andreas Finner (Trichomed Praxis Berlin) talks about what everyone can do to keep a full head of hair and about the best methods for treating hair loss:



Today's Hair-Loss Treatments: Drugs

Minoxidil shampoo

Patients can buy an OTC shampoo with an ingredient called minoxidil. Minoxidil (Rogaine) fights androgenic alopecia in both men and women. It's still not entirely clear how minoxidil works. Used properly -- twice a day, massaged deep into the scalp -- it slows new hair loss. Two-thirds of men do get acceptable hair growth. "It is not something a bald person would use, but someone starting to go bald would use it. The goal is to maintain the hair you have."

An example from Amazon:



Propecia pill

Propecia (finasteride) works only for men. It keeps the male sex hormone testosterone from forming its DHT by-product. Many men use both minoxidil shampoo and Propecia pill for maximum effect.

Today's Hair-Loss Treatments: Surgery

Surgeons can transplant hair follicles from the sides and back of the head to the top of the head.

Future Hair-Loss Treatments

- "Hair cloning" although a more accurate name is hair duplication. Follicular stem cells are packaged into follicle-inducing implants.

- Gene therapy. A gene called sonic hedgehog can convert resting hair into growing hair.

Hidradenitis Suppurativa

by , in
Hidradenitis suppurativa, also known as acne inversa, is a chronic skin disease characterized by recurrent boil-like lumps (nodules) under the skin. Hidradenitis suppurativa was once thought to be a rare condition because only the most severe cases were reported. However, recent studies have shown that the condition affects at least 1 in 100 people when milder cases are also considered.

There are three levels in the management of hidradenitis suppurativa:

- topical options
- systemic options
- surgical methods including laser therapy

Dr. Christian Baum, a Mayo Clinic dermatologist, takes a look at a chronic skin condition called hidradenitis suppurativa: overview of the condition and treatment possibilities.
