You could be walking around with an unruptured brain aneurysm. But don’t panic – the Brain Aneurysm Foundation estimates that about 1 in 50 people in the U.S. has an unruptured brain aneurysm. Director of Endovascular Neurosurgery Koji Ebersole, MD, says people are surprised to learn that the majority of aneurysms don’t cause any symptoms.

An aneurysm develops when a vessel in the brain has a thin spot, which then fills with blood, creating a bulge or balloon shape. Most brain aneurysms are small, about the size of a pea. Because the brain itself has no sensory fibers, there is no pain and the brain doesn’t register that the aneurysm is there.

“Most patients find out they have an aneurysm for a completely unrelated reason,” Dr. Ebersole says. “Maybe they’re having trouble with their sinuses and have a CT scan and the doctors find an aneurysm. When you learn you have an aneurysm, it’s important to meet with a physician who’s practiced in neurology to talk about the implications.”

Can stem cells block organ transplant rejection?


Organ transplant patients traditionally go through a grueling journey post operation, which involves a copious amount of medication for life. After years of research, Dr. Jeffrey Veale has performed a first-of-its kind surgery that could entirely change the landscape for patients. Rudabeh Shahbazi reports.

Year 2022 Basically what this means is an infinite capacity hard drive.


Exciton polaritons (polaritons herein) in transition-metal dichalcogenide monolayers have attracted significant attention due to their potential for polariton-based optoelectronics. Many of the proposed applications rely on the ability to trap polaritons and to reach macroscopic occupation of their ground energy state. Here, we engineer a trap for room-temperature polaritons in an all-dielectric optical microcavity by locally increasing the interactions between the mathrmWS_2$ excitons and cavity photons. The resulting confinement enhances the population and the first-order coherence of the polaritons in the ground state, with the latter effect related to dramatic suppression of disorder-induced inhomogeneous dephasing. We also demonstrate efficient population transfer into the trap when optically injecting free polaritons outside of its periphery.
