Outlets are reporting that Chinese scientists have genetically altered pig embryos (using added genes from mice) to create “skinny pigs” who have a lower percentage of body fat and could be used, one day, to produce what some headlines are deeming “healthy bacon.
Genetically modified (GM) foods continue to be a contentious subject. Proponents believe that it could help feed millions of hungry people amid climate change and population growth. Others balk at the idea of eating science experiments.
The World Health Organization reports that the safety of GM foods depends on how the genes were tweaked, which will ultimately leave each item to be rated on a case-by-case basis. In the United States, the Food and Drug Administration has approved genetically engineered salmon. And apples not prone to browning are expected to be available soon.
Startup Memphis Meats announced in April that it had for the first time grown chicken meat in a lab, the firm admitted that the achievement came at a cost of $9,000 per pound. Memphis Meats puts living animal cells into bioreactor tanks and feeds them oxygen, sugars, and minerals until they divide and grow. The company said the taste and texture is similar to that of the real thing, just a bit spongier, according to the Wall Street Journal. Although the company has served it’s cultured poultry to taste testers, the meat is still extremely expensive. It currently costs around $9,000 to produce a pound of Memphis Meats’ poultry, compared to a bit over $3 on average for a pound of chicken breast. However, the company hopes to reduce costs drastically as it refines its technology over the next few years. It hopes to launch a commercial product in 2021.
Business leaders like Bill Gates, Richard Branson, and Kimbal Musk have joined food industry giants like Cargill and venture capital firms in backing the startup with $17 million in a Series A round of funding. In total Memphis Meats has raised $22 million.
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.

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.
Scientist say, Genome engineering technology offers unparalleled potential for modifying human and nonhuman genomes. In humans, it holds the promise of curing genetic disease, while in other organisms it provides methods to reshape the biosphere for the benefit of the environment and human societies. However, theses opportunities come unknown risks to human health and well-being.

Indian origin Kashmiri doctor along with other scientists has developed genetically modified human embryos in the US. Led by prestigious Stanford University in the U.S., they raise public concerns that editing an embryo to fix a genetic disease, as was done this week, could be seen as “playing God” in an effort to create only the “best children” possible. This is also seen as a first step towards having “designer babies http:///2017/08/06/in-short-gene-editing-explained-in-thirty-seconds/
Scientist say CRISPR is good for eradicating disease.
