On Aug. 21, the moon will slip between Earth and sun, casting a roughly 70-mile-wide shadow that will race across the United States from Oregon to South Carolina, Whereby millions of Americans will have a chance to enjoy — and study -spectacular event. This is the first coast-to-coast total solar eclipse in 99 years. It has been dubbed, aka the “Great American Eclipse.”
Watch a live NASA stream of the eclipse as it travels across the continental United States, calculate your view with our interactive eclipse map and get a virtual view in our eclipse simulator. While you wait, check out some of the Smithsonian Astrophysical Observatory’s solar research and get even closer to the sun with near-live views from space.

Never look directly at the Sun. You can seriously hurt your eyes, and even go blind. Proper eye protection, like eclipse glasses or a Sun filter, is the only safe option. Sunglasses don’t work.
According to NASA, the following materials should never be used to view a solar eclipse:
- sunglasses of any kind
- color film
- medical X-ray film
- smoked glass
- floppy disks
Asteroid 2012 TC4 hasn’t been seen since five years ago, but calculations of its trajectory told astronomers that it would return in October 2017. NASA and the ESA plan to use it as a test run for the international Planetary Defense network, and have now been able to calculate its trajectory. To help prevent a disaster from occurring again, NASA has established the Planetary Defense Coordination Office to detect and track near-Earth objects.
Based on observations, the astronomers have determined that TC4 will pass within 50,100 km (31,130 miles) of Earth at 5:41 Universal Time on October 12, 2017. That’s 13 percent of the distance between the Earth and the Moon.
Astronomers report that viewing conditions will remain clear over the next few months as TC4 approaches, allowing them to gather more data for this and other near-Earth objects.

The study found that “motherF………” was used 678 times more often in the mid-2000s than the early 1950s, occurrences of “s..t” multiplied 69 times, and “f..k” was 168 times more frequent.
Led by Jean Twenge, author and psychology professor at San Diego State University, the team analysed the titles making up the Google Books corpus of American English books published between 1950 and 2008, looking for uses of the words “s..t”, “”, “f..k”, “c..t”, “c……r”, “motherfr”, and other curse words”.
Overall, they found that writers were “significantly more likely to use swearwords in the years since 1950”, with books published in 2005-2008 28 times more likely to include swearwords than books published in the early 1950s. The paper that was publishefd“American culture increasingly values individual self-expression and weaker social taboos, and these trends are manifested in the increasing use of swearwords.”
Twenge and her fellow authors, graduate student Hannah Van Landingham and University of Georgia psychology professor W Keith Campbell, link the rise of profanities in US literature to the increasingly individualistic nature of the country’s culture, as well as the relaxation of societal taboos.
In a technique called spindle nuclear transfer, the nucleus of a donor egg is removed and the DNA of another woman’s egg is injected.
The FDA is taking a hard stance on a controversial fertility technique that involves genetically modifying embryos.
The New York-based doctor who helped a couple have a child using DNA from three people has been told by the U.S. Food and Drug Administration to stop the clinical trials meant to test the technique.
Last year, John Zhang, the founder of New Hope Fertility Center, pioneered a new type of in-vitro fertilization that involves transferring DNA from the mother’s egg into a hollowed-out egg donated by a younger woman. But the work violates federal legislation that forbids implanting genetically modified embryos, so after fertilizing the egg with the father’s sperm, Zhang went to Mexico, where he inserted the embryo into the mother’s womb. A healthy baby boy was born in April 2016.
FDA sends Zhang a letter
Zhang then requested a meeting with the agency to ask permission to carry out a clinical trial using the technique in the U.S. The agency subsequently denied the meeting. Zhang has since been marketing his fertility procedure to women with certain genetic diseases and older women having trouble conceiving through a new company called Darwin Life. Modifying embryos in a lab is not illegal under U.S. law as long as federal funds are not used to carry out the work. But implanting one in a woman’s womb so that a baby can develop is prohibited.
Hospitals around the world are constantly for new and innovative ways to battle deadly pathogens and kill multidrug resistant organisms that can cause hospital-acquired infections (HAI).
Saint Peter’s University Hospital has implemented a LightStrike Germ-Zapping Robot that emits waves of ultraviolet (UV) light to destroy hard-to-kill bugs in hard-to-clean places.
Their goal is to prevent infection & provide a clean, safe environment for their patients, families and employees. The latest technology provides an added level of protection in combating HAI’s caused by pathogens such as Clostridium difficile and Staphylococcus aureus.
The Xenex robot is a new technology that uses pulsed xenon, a high-intensity UV light that penetrates the cell walls of microorganisms, including bacteria, viruses, mold, fungus and spores. Their DNA is fused, rendering them unable to reproduce or mutate, effectively killing them on surfaces without contact or chemicals.
The system is effective against even the most dangerous pathogens, including Clostridium difficile (C. diff), norovirus, influenza, Ebola and methicillin-resistant Staphylococcus aureus, better known as MRSA. Over 400 hospitals, Veterans Affairs and Department of Defense facilities in the U.S., Canada, Africa, Japan and Europe are using Xenex robots, which are also in use in skilled nursing facilities, ambulatory surgery centers, and long-term acute-care facilities.
A security researcher Marcus Hutchins, 22, a British national, who in May stopped an outbreak of the WannaCry ransomware has been arrested and detained after attending the Def Con conference in Las Vegas. Hutchins was arrested at Las Vegas airport on Wednesday by US Marshals, several close friends have confirmed.
A Justice Department spokesperson has confirmed on the phone that his arrest is in relation to his alleged role “in creating and distributing the Kronos banking Trojan.”
The indictment was dated July 11, about two weeks before he flew to the US to attend the annual security conference. The Justice Department has been after those involved with the notorious Kronos malware for more than two years.
Hutchins, also known as @MalwareTechBlog, stormed to fame after he found a kill switch in the malware, known as WannaCry, amid a global epidemic of ransomware. Hutchins registered a domain name that stemmed the infection.
He was hailed as a hero for stopping the attack, which gripped UK hospitals and other major industries around the world.
