Talc is a clay mineral composed of hydrated magnesium silicate with the chemical formula Mg3Si4O10(OH)2. Talc in powdered form, often in combination with corn starch, is widely used as baby powder. This mineral is used as a thickening agent and lubricant, is an ingredient in ceramics, paint and roofing material, and is also one of the main ingredients in many cosmetic products.
The Mohs scale of mineral hardness is based on scratch hardness comparison, ranging from 1-10, a value of 10 being the hardest of minerals. Talc is the defining value 1 and therefore the softest of minerals. Any mineral below a value of 2 on Mohs scale of mineral hardness can be scratched by a fingernail. When scraped on a streak plate it produces a white streak, though this indicator is of little importance because most silicate minerals produce a white streak. Talc is translucent to opaque with colors ranging from whitish grey to green with a vitreous and pearly luster. Talc is not soluble in water, but is slightly soluble in dilute mineral acids.

With a Mohs scale number of 1, talc is the softest mineral, and, when smooshed into a fine powder, it's the number 1 product to keep your babies free of diaper rash. But it may be responsible for some older girls getting cervical cancer!!!

I looked up the answer, because I had no idea. It's talc…the basis of talcum powder, and baby powder. It's almost as absorbent as corn starch.

Info: "I hadn't written a folk song in almost 20 years although I had loads of material from earlier on that I wanted to record. After watching Athens, OH singer songwriter Megan Bee perform at LEO Coffeehouse in Cincinnati, I was inspired to write 'My Reverie'. 'A Song For April' is an instrumental with guitar and bagpipes written for five-year-old April Jones from Wales who disappeared in October 2012. Originally, before it was found that she'd been murdered, it was a song of hope that April would be found alive (my own daughter was nine at the time)." - Dave "Hedgehog" Mason
Price: $1 (USD) for song; $5 (USD) for 10-song album
• When Molly Ringwald was in the 2nd grade, she wanted to be a jazz singer. (Today, she sings jazz in a group for fun.) When her class was given the assignment of doing a presentation on a great American hero, most kids did their projects on such prominent Americans as George Washington, but she did her project on the prominent American jazz singer Bessie Smith. On American Life Story day, she showed up at school dressed in 1920s clothing, and she performed a few Bessie Smith songs such as "Gimme a Pigfoot and a Bottle of Beer." (Molly says, "Miss Kestenbaum was a very progressive 2nd-grade teacher.")
• When Sharon Salzberg and others established the Insight Meditation Society in Barre, Massachusetts, in 1975, she began a week of intense meditation. Unfortunately, it was a very boring week, and as she sat meditating on lovingkindness and directing lovingkindness toward herself, she felt as if she were accomplishing nothing. But when she was packing some belongings, she dropped a jar, which shattered. Her first thought was, "You are really a klutz, but I love you," and her second thought was, "Wow! Look at that. Something did happen in this week of practice."
• Tenor Rolando Vallazón was discovered - in a way - in the shower. At age 11 or 12, he was singing a song by Baloo from The Jungle Book in the shower when the director of the Academy of Performing Arts heard him and knocked on the door. He asked Rolando's mother, "Who's singing up there?" She replied, "I'm sorry. I'll tell him to shut up." He objected, "No, no. We're starting a program for young people, and maybe he'd be interested in singing." Rolando went there, he discovered that he enjoyed being on stage, and now he has an international career singing in opera.
• Very often, the Navajo do important actions just before dawn. When 10-year-old Jaclyn Roessel and her Nalí Ruth ("nalí" means "father's mother or father") went searching for wild plants to use to dye wool, they did so early in the morning. Jaclyn asked, "Why do we always do things when it is still dark?" Nalí Ruth answered, "The Holy People [Navajo spiritual beings] taught us that there is wisdom and beauty in the darkness before dawn. If you sleep in, you miss it." By the way, the Navajo have a wide meaning for the word "aunt." An aunt is any older female relative.
• A man of wit, author George Plimpton once had a calling card that said, "If you plan to commit arson, murder, larceny, adultery, etc., notify George A. Plimpton, Boston Herald correspondent." And supposedly, when he left Cambridge, he had to take a three-hour test that had exactly one question: Who was Charles James Fox?" Mr. Plimpton had no idea who Charles James Foxwas, so he made up stuff up: "Charles James Foxwas a rather mediocre second baseman for the Cincinnati Reds …."
• In June of 2010, Jane Schwanbeck retired from Lomarena Elementary School in Laguna Hills in South Orange County, California, after 37 years as a kindergarten teacher - she spent 36 of those years in the same room! When she retired, her students gave her testimonials. For example, TJ, who was in her kindergarten class that year, said, "I feel like she's the best teacher I've ever had." And Kirsten said what many students said, "What I'm going to say is that I love my teacher."
• Architect Frank Gehry designed the Ray and Maria Stata Center for Computer, Information, and Intelligence Sciences at the Massachusetts Institute of Technology. Mr. Gehry knew that MIT is noted for its "endless corridor" - a corridor that winds throughout the school, so he designed a Student Street for the Stata Center and connected it to the endless corridor. Apparently, students approved of it because one student wrote on a chalkboard, "Frank Gehry, we love you."

Bill Nye the Science Guy is taking the runway by storm!
On Wednesday, the beloved science star strutted his way down the runway at The Blue Jacket Fashion Show at Pier 59 Studios for New York Fashion Week.
At one point, the 64-year-old - who was rocking a tuxedo designed by Nicholas Graham that featured a blue jacket with floral brocade - even started dancing to Lizzo's "Juice" as it played in the background.
Others who walked the special runway this year included Viktor Cruz, CC Sabathia of the New York Yankees and Don Lemon from CNN.
An Oscar nomination can open doors to bigger roles and higher pay. This year, it also comes with a cruise on a luxury yacht, cosmetic surgery, and a personal matchmaking service in a gift bag worth more than $225,000.
The gift bag, which is not affiliated with the Academy of Motion Picture Arts and Sciences, will be sent to all 20 acting nominees and the five men nominated for best director, Distinctive Assets, the Los Angeles-based company behind the goodie bags, said on Friday.
This year's top swag includes a $78,000, 12-day yacht cruise; $20,000 of facial rejuvenation treatments; and $20,000 in matchmaking services.
The nearly 80 items also include clothing, gadgets and a 24-carat gold-plated vape pen that Fary said was selected with Leonardo DiCaprio in mind. Photos of DiCaprio vaping a few years ago helped popularize the trend
A massive firework launched over a Colorado ski resort town has set a record for the world's largest aerial firework.
The 2,800-pound (1,270-kilogram) shell flew 2,200 feet (671 meters) above the Steamboat Springs Winter Carnival before it burst, turning the sky bright red and drawing gasps from the crowd, The Steamboat Pilot & Today reported.
Tim Borden of Steamboat Springs headed the team that developed the firework over seven years. Borden first attempted to set the world record last year, but failed when the shell exploded inside the mortar without lifting off the ground, the newspaper reported.
Guinness World Records representatives witnessed both attempts. Christina Conlon of Guinness said she verified the shell launched Saturday was the world's largest.
The firework was 400 pounds (181 kilograms) heaver than the previous record-holder, a 2,397-pound (1,087 kilograms) explosive launched in the United Arab Emirates in 2018.
Swiss voters approved by a wide margin Sunday a measure that will make it illegal to discriminate against people because of their sexual orientation.
Switzerland's parliament in late 2018 approved expanding the country's existing anti-discrimination law to make it illegal to publicly denigrate, discriminate or stir up hatred based on a person's sexual orientation.
Opponents of the move insisted it violated people's right to freedom of opinion and gathered enough signatures to force a referendum on the issue. Switzerland holds referendums several times a year that give voters a direct say in policy-making.
Voters supported outlawing anti-gay discrimination by a margin of 63.1% to 36.9%, an outcome roughly in line with pre-referendum expectations. Of Switzerland's 26 cantons (states), only three - Appenzell-Innerrhoden, Schwyz and Uri - had majorities vote against it.
Under the measure, operators of restaurants, cinemas and public facilities such as swimming pools will not be able to turn people away because of their sexual orientation.
Conservative talk Hate radio host Rush Limbaugh (R-Oxycontin) said President Donald Trump (R-Aderall) asked him to postpone his "serious" cancer treatment so he could attend the president's State of the Union address.
Limbaugh was awarded the Presidential Medal of Freedom at the SOTU on Tuesday, one day after Limbaugh announced he was diagnosed with advanced lung cancer.
The political commentator said on his radio show he was going to start his treatment Tuesday evening until he received a call from the president saying to show up in Washington as his personal guest at the SOTU.
After telling the president he had a "serious medical procedure" scheduled for later that day, Trump said he wanted to call Limbaugh's doctor and "have him delay it for a couple days ''cause I need you down here tonight.'"
"'Look, your health comes first; there's no question,'" Trump said, citing the transcript of Limbaugh's show. "'But can't they just do half of what they're gonna do and then send you down here? Believe me, you don't want to miss this. It's gonna be great. It's gonna be great. You don't want to miss this.'"
Four endangered mountain gorillas, including three adult females, have been killed by an apparent lightning strike in a Ugandan national park, a conservation group has said.
A post-mortem examination has been performed on the four, including a male infant, who died on February 3 in Mgahinga National Park in southwest Uganda.
"Based on the gross lesions from the post-mortem... the tentative cause of death for all four individuals is likely to be electrocution by lightning," the Greater Virunga Transboundary Collaboration (GVTC) said in a statement Saturday, although laboratory confirmation will take two to three weeks.
The four were members of a group of 17 known as the Hirwa family which had crossed into the Mgahinga National Park in August last year from Volcanoes National Park in neighbouring Rwanda.
In 2008, there were estimated to be only 680 of the great apes left but thanks to conservation efforts and anti-poaching patrols, their population has grown to more than 1,000.
At a glance, the desert locusts in this arid patch of northern Somalia look less ominous than the billion-member swarms infesting East Africa in the worst outbreak some places have seen in 70 years.
Small and wingless, the hopping young locusts are the next wave in the outbreak that threatens more than 10 million people across the region with a severe hunger crisis.
And they are growing up in one of the most inaccessible places on the planet. Large parts of Somalia south of this semi-autonomous Puntland region are under threat, or held by, the al-Qaida-linked al-Shabab extremist group. That makes it difficult or impossible to conduct the aerial spraying of the locusts that experts say is the only effective control.
Somalia has declared the outbreak a national emergency. Across the region, it has the potential "to be the most devastating plague of locusts in any of our living memories if we don't reduce the problem faster than we're doing at the moment," U.N. humanitarian chief Mark Lowcock said.
Then they are expected to set off for neighboring Kenya and Ethiopia, where a handful of planes spraying pesticide can only do so much if such swarms keep arriving.
A mysterious radio source located in a galaxy 500 million light years from Earth is pulsing on a 16-day cycle, like clockwork, according to a new study. This marks the first time that scientists have ever detected periodicity in these signals, which are known as fast radio bursts (FRBs), and is a major step toward unmasking their sources.
FRBs are one of the most tantalizing puzzles that the universe has thrown at scientists in recent years. First spotted in 2007, these powerful radio bursts are produced by energetic sources, though nobody is sure what those might be. FRBs are also mystifying because they can be either one-offs or "repeaters," meaning some bursts appear only once in a certain part of the sky, while others emit multiple flashes to Earth.
Pulses from these repeat bursts have, so far, seemed somewhat random and discordant in their timing. But that changed last year, when the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/FRB), a group dedicated to observing and studying FRBs, discovered that a repeater called FRB 180916.J0158+65 had a regular cadence.
The CHIME/FRB team kept tabs on the repeating burst between September 2018 and October 2019 using the CHIME radio telescope in British Columbia. During that period, the bursts were clustered into a period of four days, and then seemed to switch off for the next 12 days, for a total cycle of about 16 days. Some cycles did not produce any visible bursts, but those that did were all synced up to the same 16-day intervals.
Scientists recently tracked down this particular FRB to a galaxy called SDSS J015800.28+654253.0, which is a half a billion light years from Earth. That may seem like a huge distance, but FRB 180916.J0158+65 is actually the closest FRB ever detected.
"Birds of Prey," the DC Comics' Harley Quinn spinoff, made a tepid debut in theaters over the weekend, opening in No. 1 but below expectations with $33.3 million domestically, according to studio estimates Sunday.
Warner Bros. said the coronavirus impacted sales in Asia, though in South Korea, where "Birds of Prey" made $1.9 million, it came in second to a local release. "Birds of Prey" doesn't have a China release scheduled, and "Suicide Squad" never opened there. Cinemas in the country, the world's second largest movie market, have shut down amid the coronavirus outbreak.
After three weeks atop the box office, Sony Picture's "Bad Boys for Life" dropped to second with $12 million in its fourth weekend. The action comedy, which reunites Will Smith and Martin Lawrence, has grossed $336 million worldwide.
Holdovers "Doolittle" ($6.7 million in its fourth weekend) and "Jumaji: The Next Level" ($5.5 million) rounded out the top five.
Estimated ticket sales for Friday through Sunday at U.S. and Canadian theaters, according to Comscore.
1. "Birds of Prey," $33.3 million ($48 million international).
2. "Bad Boys for Life," $12 million.
3. "1917," $9 million.
4. " Doolittle," $6.7 million.
5. "Jumanji: The Next Level," $5.5 million.
6. "The Gentlemen," $4.2 million.
7. "Gretel & Hansel," $3.5 million.
8. "Knives Out," $2.4 million.
