How the treatment worked:
1) One of the patient's two olfactory bulbs was removed and the olfactory ensheathing cells (OECs) were grown in culture
2) 100 micro injections of OECs were made above and below the damaged area of the spinal cord
3) Four strips of nerve tissue were placed across an 8mm gap in the spinal cord. The scientists believe the OECs acted as a pathway to stimulate the spinal cord cells to regenerate, using the nerve grafts as a bridge to cross the severed cord
Darek Fidyka, who was paralysed from the chest down in a knife attack in 2010, can now walk using a frame.
The treatment, a world first, was carried out by surgeons in Poland in collaboration with scientists in London.
Details of the research are published in the journal Cell Transplantation.
Incoming student Ashlyn TenBieg was shocked to find out that she was the only freshman in the online group without a roommate. While for some, this would be an ideal situation – no roommates to filthy up the bathroom, the ability to run around your room pantsless, no one to judge you for having nachos for dinner (again!) – TenBieg wanted the full college experience, living with a stranger and all.
She called the UCF housing office to inquire about the issue, and she learned that not having a roommate was the least of her problems. "[The representative from the housing office] told me that they mistakenly placed me in a bathroom and that I will get a new assignment," TenBieg told Knight News, "I thought the lady was just joking at first when she told me, because she said it so casual."
One of the world's great radio telescopes isn't hearing voices – for the first time another giant dish has picked up one of the mysterious "fast radio bursts" (FRBs) that have been puzzling astronomers at the Parkes Radio Telescope. The find confirms these bursts indeed come from outer space, but beyond that their source is still wide open.
Last year the astronomers reported four bursts picked up by the celebrated Australian telescope. As each FRB lasted around a millisecond there was no time to have other telescopes check the same location, and the fact that no other telescope had picked up anything similar raised the possibility that something local was interfering with the Parkes telescope.
Now, however The Astrophysical Journal reports that the 305m Arecibo Telescope has picked up a similar burst while searching for pulsars. The burst occurred in 2012, but not noticed at the time. "FRB 121102's brightness, duration, and the inferred event rate are all consistent with the properties of the previously detected Parkes bursts," the authors report.
As early as 2018, solar could be economically viable to power big cities. By 2040 over half of all electricity may be generated in the same place it's used. Centralised, coal-fired power is over
Last week, for the first time in memory, the wholesale price of electricity in Queensland fell into negative territory – in the middle of the day.
For several days the price, normally around $40-$50 a megawatt hour, hovered in and around zero. Prices were deflated throughout the week, largely because of the influence of one of the newest, biggest power stations in the state – rooftop solar...
