Meet The First 2 Black Women To Be Inducted Into The National Inventors Hall Of Fame

National Inventors Hall of Fame has been around for nearly five decades but hasn't included any Black women in its ranks — until now. Engineer Marian Croak and the late ophthalmologist Patricia Bath will make history as part of the next cohort of inductees, the nonprofit announced this past week.

They are the first Black female inventors to receive this honor, which has been bestowed on some 600 other innovators both living and dead.

James W. Loewen, wrote ‘Lies My Teacher Told Me,’ dead at 79 NEW YORK (AP)

James W. Loewen, whose million-selling “Lies My Teacher Told Me” books challenged traditional ideas and knowledge on everything from Thanksgiving to the Iraq War, has died.

He was 79.

Loewen’s publisher, New Press, announced that the author died Thursday at Suburban Hospital in Bethesda, Maryland.

A professor emeritus at the University of Vermont who lived in Washington, D.C., he had been diagnosed two years ago with Stage IV bladder cancer, enough time for him to post “Notes toward an obituary” on his website. “Telling the truth about the past helps cause justice in the present,” was his guiding principle, he wrote. “Achieving justice in the present helps us tell the truth about the past.” Loewen’s “Lies My Teacher Told Me: Everything Your American History Textbook Got Wrong” was published in 1995 and became a favorite of students and former students as it challenged what Loewen considered a white, Eurocentric view of the past and the stale prose and bland presentations of classroom books.

Amazing Mehmet Aziz!

hey called him The Great Liberator. His name was Mehmet Aziz and he was behind one of Cyprus's most important achievements of the last century. And yet no-one apart from a handful of Cypriots has heard of him.

Aziz was a Turkish Cypriot health official who ensured that Cyprus became the first malarial country in the world to completely eradicate the disease.

Known to his compatriots as "the fly man", he had studied under Nobel-prize winning malaria specialist Sir Ronald Ross, who had found the type of mosquito that transmitted the disease. I came across Aziz's story accidentally in the course of researching a book about British colonial Cyprus.

By 1936, Cyprus - then a British colony - was known as one of the world's most malarial countries, with around 18,000 cases every year. The disease was particularly devastating for children. One elderly man, recalling his childhood, explained that "an awful lot of youngsters never made it, others were not fit to do a day's work after contracting the disease"

pioneered a technique to minimise its use, pouring a thin petroleum film on to water surfaces to prevent mosquito larvae from hatching. According to the Cyprus Review of June 1948, "every pool and stream and area of water-logged ground" was sprayed with insecticide. Even the hoof-prints of animals were treated. Aziz's men waded into marshes and were lowered into caves by ropes.

Spencer Silver, who helped invent the Post-it Note, dies at age 80

The inventor of the adhesive used on the Post-it Note has died, according to the company 3M, which produces the product, and his published obituary. Spencer Silver was 80 and died May 8 at his home, the family’s obituary said. Silver was working in a company lab in 1968 when he discovered a unique adhesive formula, according to 3M. The adhesive allowed notes to be easily attached to surfaces, removed and even re-posted elsewhere without leaving residue like other glues. Silver looked for several years for a practical use for the adhesive, calling it a “solution waiting for a problem to solve”. In 1974, his colleague Art Fry came up with the idea of using the adhesive to prevent paper bookmarks from falling out of his hymnal when he sang in church.

The product was originally called the Press ‘n’ Peel memo pad in 1974, but it wasn’t brought to the market until 1977 and didn’t really take off until 1980, when it was renamed the Post-it Note. It’s now one of the top-selling items in 3M’s consumer products divisio

Kilogrammet utbytt – nu mäts vikt och längd på ett nytt sätt

En historisk händelse – på gränsen till en mätteknisk revolution. Så beskrivs det faktum att kilogrammet nu är utbytt på riktigt. Sedan en tid tillbaka är ett kilogram inte längre ett kilogram. Inte riktigt, i alla fall.

I februari i år övergick man nämligen till ett helt nytt system för att uppskatta hur mycket ett kilogram egentligen är.

IBM 2nm chip breakthrough claims more power with less energy

IBM says it has made a significant breakthrough in computer processors by creating a 2nm chip in its test lab. The process used to make computer chips is measured in nanometres (nm) - with a lower number usually signifying a leap forward.

IBM claims its test chip can improve performance by 45% over current 7nm commercially available products.


In the recent study, researchers used ultrashort laser pulse excitation as the stimulus to optically stimulate specific atomic vibrations of the magnet.

This, as a result, "extensively disturbed and distorted" the structure of the material.

Fermilab and partners achieve sustained, high-fidelity quantum teleportation

A viable quantum internet — a network in which information stored in qubits is shared over long distances through entanglement — would transform the fields of data storage, precision sensing and computing, ushering in a new era of communication.

This month, scientists at Fermilab, a U.S. Department of Energy Office of Science national laboratory, and their partners took a significant step in the direction of realizing a quantum internet.

RNAi pesticides!

The Time is Now for Genomics-informed RNAi Pesticidal Solutions

Knowledge of RNA interference is relatively new. In 1998 the American scientists Andrew Fire and Craig Mello first published their discovery of RNAi. They would go on to receive the 2006 Nobel Prize in Physiology or Medicine for their work. RNAi is a natural cellular process in fungi, plants, animals, and humans that has the function of disrupting or “silencing” the production of a specific gene product, such as a protein, to maintain normal growth and function.
