Ryan from ScienceN60 is guest hosting this World 5 List of Scientific discoveries of 2014
The Original Eskimo’s Are Gone
– The first people in Alaska, Canada, and Greenland arrived 6,000 years ago from Siberia.
– Recent genetic testing says they all disappeared about 700 years ago. Which is rare.
– Several waves of people migrated in between that were the ancestors of todaysinuits but the original group never interbreed with them and their genetic line ended 700 years ago.
The Closest Exoplanet, outside our solar system, was discovered
– It’s in a system with 2 red dwarf stars that are close enough to seen with binoculars
– Red dwarfs are the most common type of star in the Milky Way galaxy.
– And the planet is rocky and about 5x earth’s mass making it a “Superearth”
Water vapor clouds have been found around a star.
– It’s a brown dwarf star which arefailed stars that never got big enough to start nuclear fusion in their core.
– 50% of it is covered by clouds probably made of sulfide & water
– These are the only clouds containing water ever discovered outside our solar system
The First functional organ was grown in a lab in Edinburgh
– It was a thymus which matures T cells for our immune system.
– Scientists artificially producing and programing the cells before implanting them.
– The ability to grow replacement organs is the holy grail of regenerative medicine.
– The first success being part of our immune system has multiple potential uses
Blood from Eebolabola survivors may be used as a cure for the current outbreak in Africa.
– Dr Kent Brantly started the trend when he received a transfusion from a 14 year old survivor and walked out of the hospital last week.
– Our bodies build up antibodies to diseases we recover from and they stay in our blood for a lifetime and can, on occasion, be transfused into other people
– With no ebolavaccineavailible the World Health Oranization is lookinginto doing just that.
– After the donors have been screened for other diseases like malaria and HIV first.
