Can you summerize this? Robot surgeons could one day have an easy way to mend internal injuries with minimal impact. MIT researchers have developed an “origami-inspired,” biodegradable medical patch that can be folded around a robot’s minimally invasive surgical tools to seal internal damage.

While bioadhesive patches are already in use for this kind of surgery, they can create flawed seals and even do their own damage, like inflammation and scar tissue. MIT’s design solves these issues through a three-layer patch with a hydrogel-based adhesive, a silicone oil-coated material to prevent unintended sticking and an elastomer outer layer whose zwitterionic nature (that is, a molecular chain with positive and negative ions) protects the patch against bacteria.

The result is a tape that easily wraps around robotic tools while adhering strongly to tissue, even after it has been immersed in fluid for long periods. A test patch avoided contamination even after a month, too. A robot might only need to apply light pressure or inflate a balloon to apply a patch.

Any practical application might take a long while. However, the scientists envision companies selling prefolded patches that would slip on to existing tools. They’re hoping to collaborate with robotic surgery platform developers. If that happens, you could see greater use of robots and bioadhesives in the medical world — not to mention gentler recoveries from some procedures.

the correct answer is the name of the author of the quotation appears at the text leading up to it   apex 2018

while his customary satire is present in mark twain's short story "the notorious jumping frog of calaveras county," there is a cloaking of this satire as twain's narrator is not directly involved. another literary device that you could build a thesis around is the use by twain of hyperbole.

laughter and happiness are an essential part of life. laughing releases the body's "feel good" chemicals. thus, it provides long or short term relief from stress and or anxiety. more or less, laughing strengthens social connections and provides an easy approach in social related situations.

moreover, there are many benefits of laughter and humor. it's as if they play the role of superhero to combat anxiety and depression, according to researchers. happiness and laughter is the best medicine for teen mental health.

what happens in the body also affects the mind. the positive changes in physical health also have profound an impact on mental health. we have a lot to gain from laughing! medical effects of laughter have continued to validate the pain-relieving effect and benefits of laughter.

scientists tell us that laughter and humor actually, believe it or not, lower blood pressure, reduce stress hormones and increase muscle flexion. there are many benefits to happiness and laughter, and they so happen to increase the circulation of antibodies in the blood stream and make us resistant to infections.

as stated before, laughing releases your body's "feel good" chemicals, and on a related note, negative stress can cause your body to release chemicals that weaken your immune system which makes you more likely to contract a disease. luckily, laughter reduces negative stress and prevents those chemicals from being released.

all in all, you may want to consider laughing as much as you can!
