A new kind of lotion could one day help diabetic patients heal stubborn and painful ulcers on their feet, say researchers.
Scientist and dermatologist Amy S. Paller and chemist Chad A. Mirkin
are the first to develop a topical gene regulation technology that
speeds the healing of ulcers in diabetic animals.
They combined spherical nucleic acids (SNAs, which are nanoscale
globular forms of RNA) with a common commercial moisturizer to create a
way to topically knock down a gene known to interfere with wound
The National Institute of Arthritis and Musculoskeletal and Skin
Diseases, the Center for Cancer Nanotechnology Excellence Initiative of
the NIH/National Cancer Institute, and the NIAMS-funded Northwestern
Skin Disease Research Center supported the research.
OP:Okay guys, I know we all got in here because we’re smart, so what are your guys’ SAT and ACT scores and gpa. Just wanna see how smart we really are and scope out some friendly academic competition
Some of the responses:
"2500 SAT, 37 ACT, over 9000 GPA on a 4.0 scale"
"Taking ACT again next week to see if I can improve my score…"
"1.25 GPA, -3 ACT but that was with tutoring so I can’t take all the credit!"
"36 ACT 2390 SAT 4.922 GPA Mensa approved scholar. IQ of 147. 5’10" roughly 136 pounds, brunette, lanky, kinda cute, last seen wearing white hoodie and cargo pants. Responds to the name Lafaunda. Approach with caution."
"I’m getting an A in PE for the 4th straight year now."
"My highest score was 63 on Flappy Bird"
"My snapchat score is 28,948"
"I once got more than 200 likes on a Facebook status"
If your walk down Sheridan Road is a bit more starry-eyed today, that’s because the Northwestern Society of Physics Students spent four hours last night chalking a scale model of the solar system from the Arch to Tech. They also partnered with colleagues in Oxford, who have drawn Proxima Centauri–the nearest star to the sun–on their campus to represent that distance.
Alzheimer Amyloid Clumps Found in Young Adult Brains
Amyloid – an abnormal protein whose accumulation in the brain is a hallmark of Alzheimer’s disease – starts accumulating inside neurons of
people as young as 20, a much younger age than scientists ever imagined,
reports a surprising new Northwestern Medicine study.
Scientists believe this is the first time amyloid accumulation has
been shown in such young human brains. It’s long been known that amyloid
accumulates and forms clumps of plaque outside neurons in aging adults
and in Alzheimer’s.
