This statistic displays the number of organ transplant candidates in the United States by organ, as of as of September 25, 2019. At this moment, there were 230 candidates in the country waiting for an intestine donation. Organ donation can be given through both a deceased and living donor if blood and oxygen are flowing through the organs until the time of recovery to ensure viability. There are over 120,000 people in the country waiting for an organ transplant.
Before his death, Stephen Hawking submitted a research paper that predicts the end of the world.
Just two weeks before his death, renowned physicist Stephen Hawking submitted a research paper that suggests parallel universes and predicts the end of this one.
Hawking and his co-author Thomas Hertog published their research in “A Smooth Exit from Eternal Inflation,” detailing how scientists may also be able to detect other universes using a spaceship. According to Hertog, Hawking finished writing the paper from his deathbed, leaving behind a final legacy that is worthy of the Nobel Prize.

Not only are people still coming up with new drone applications, but they are also still coming up with new drone designs. How about the SQUID drone that is launched from a cannon mounted in the bed of a moving truck. Once the SQUID reached a certain altitude, it deploys and flies away like a ‘normal’ drone.
100% Solar Yachts are catching on in a big way. Impressive.

While propeller planes certainly do have their place, sometimes the extra speed and thrust of a jet engine is what’s really needed. Dallas, Texas-based FusionFlight has applied that sort of thinking to quadcopter-style drones, resulting in the AB5 JetQuad.
According to the company, the AB5 is “the world’s smallest and most powerful jet-powered drone with vertical take-off and landing [VTOL] capabilities.”

NASA astronaut Nicole Stott examines scenes depicting space from movies and television and breaks down how accurate they really are. What actually happens when your helmet cracks in space like in Total Recall? Are the spacewalks in Gravity realistic? Could there really be AI on a space station like in 2001: A Space Odyssey?

Medication prescribed for a certain type of epilepsy may offer a new method for treating malignant infantile brain tumors. A specific mTOR inhibitor has the ability to cross the blood-brain barrier to both reach and attack the tumor at source. This has been demonstrated by researchers from Uppsala University, in collaboration with US and UK colleagues, whose research has now been published in the scientific journal Cell Stem Cell.
Approximately 100 children suffer infantile brain tumors in Sweden each year. The most common type of malignant brain tumor in infants and children is medulloblastoma. Radiation therapy is part of the standard treatment for medulloblastomas and modern radiation therapy has saved the lives of many children suffering from these often aggressive cancers; however, as it often comes with serious side effects for healthy brain tissue, it is seldom prescribed for infants. Although a presumably better solution would be to give more targeted treatment, in order to establish such a therapy it would naturally need to be proven to be both more effective and come with fewer side effects than current treatments.
Many infantile medulloblastomas are amplified by MYCN, an oncogene that drives tumor growth and metastasis to the spinal column, leading to a very poor prognosis. In the study in question, the researchers cultivated a particular type of neural stem cell and were able to demonstrate that MYCN was quickly able to turn these into cancer cells. This suggests that these cells are likely to be the origin of infantile medulloblastomas.
