Securus Calls Attention to Global Tek Link Improprieties

Securus Technologies is a provider of services to various law enforcement and public service agencies across the US. As a business that serves the needs of the community, either directly or indirectly, it is committed to meeting high professional standards and strives to be a leader in the industry.

In an effort to call out those who unfortunately have not held such standards, Securus is releasing a series of reports that discuss the wrongdoings of Global Tek Link (GTL). GTL was tasked to provide communication services to the inmates of Louisiana.

Through an investigation ordered by the Louisiana Public Service Commission in the late 1990s, it was found that GTL carried through actions that led to overcharges of over a million dollars. Those actions included adding time to calls, double-billing calls, charging calls at high rates, and adding miscellaneous charges to calls. All of these were allegedly done deliberately to inflate the company’s bottom line.

At Securus, transparency is vital to the company’s success. Over the next six months, other reports will delve further into what happened at GTL. By reminding people of the misconduct carried out by a major player in the field, company leaders hope to make others think twice about doing anything unethical.

Handy’s Tipping Feature Has Broken Headlines

Handy is an outstanding platform through which independent cleaners can find jobs rather easily for a low fee. Many home cleaners cannot afford advertising or promotional costs like large corporations can, so Handy is an important breakthrough in the gig economy as far as services around the home are considered. Handy has other people that do plumbing, carpentry work, and other services to make a home both look and perform better.

Handy has recently implemented a new feature in which clients are now able to tip cleaners for the work they have done that has been performed above and beyond expectations. Some people tip just to give the cleaner a little more money. Tips have only been able to be given in cash in the past, so if a person was outside of their home and was not there when the cleaner finished the job, they would have to go through trouble just to give them a little bit of a tip.

Other apps like Lyft have recently added a tipping feature for their independent contractors which has resulted in a heavy influx of people giving tips, which have not been given frequently in the past. Restaurants and other businesses always have receipts in which customers can give tips, but apps like Uber, Lyft, and Handy have not always had these services. Thankfully for both clients and cleaners, this tipping service has added to the dynamics of Handy.

Handy was founded by Mr. Umang Dua and Mr. Oisin Hanrahan, who were both roommates at Harvard Business School. In their first year, after discovering that there was a need for a place to list home cleaning services, they dropped out because they felt as if they should not miss out on the opportunity to start their application and cleaning service. This turned out to be a great idea receiving over $50 million in funding just this year.

The school of thought on tipping had recently been brought to the spotlight a few months ago when restaurant tipping was widely debated. Handy implemented the ability to tip not only to squash this argument of Handy being against tipping, but to help out the cleaners and clients and make the experience lots more enjoyable.

New Device Separates Cancer Cells With Sound Waves

A team of researchers at Carnegie Mellon University have developed a device that separates cancer cells from healthy by sound waves.

This is a microchip that, in theory, improves the diagnosis and treatment of cancer, in addition to deepen the research on metastasis, the leading cause of death in patients with this disease.

Bernardo Chua ( has learned that the apparatus enables the sound waves to separate the existing cancer cells from hundreds of thousands of white blood cells, regardless of which are much less dense and smaller.

Thus, this development can replace the current techniques of genetic analysis of cancer.
Separating Cancer Cells With Sound Waves

The new technique, published in the journal “Proceedings of the National Academy of Sciences” ( PNAS ), allows for analysis of cells up to 20 times faster than current methods.

Scientists have used the new test with real blood samples of three women with breast cancer, obtaining consistent results.

Moreover, the laboratory experiment with plasma samples prepared with low levels of cancer cells revealed that the device is capable of separating 83% of tumor cells.
