Hobbiten Homo floresiensis en sne' pygmé
Kraniet är asymmetriskt, och muskelfästen samt benstruktur matchar inte bentjocklek.
They have two options: they could expose their procedures and theory to the scientific community for review or they could make tons of money with the best trade secret in history. What do they do? C) none of the above. They declare they've got it, thus ruining their chances of keeping it secret if they actually do begin making money off it, but they don't let anyone actually know what it is, with the possible exception of a jury of "scientists" they handpick. Doesn't that sound a little fishy?
I am very impressed with the number of substitutions on the human lineage compared with other vertebrates. The region is highly conserved: only two bases are different between chimpanzees and chickens. In contrast, there have been 18 substitutions on the human lineage! It's like every other species is driving the same Plymouth Reliant, and humans are driving a Ferrari!
We devised a ranking of regions in the human genome that show significant evolutionary acceleration. Here we report that the most dramatic of these 'human accelerated regions', HAR1, is part of a novel RNA gene (HAR1F) that is expressed specifically in Cajal-Retzius neurons in the developing human neocortex from 7 to 19 gestational weeks, a crucial period for cortical neuron specification and migration. HAR1F is co-expressed with reelin, a product of Cajal-Retzius neurons that is of fundamental importance in specifying the six-layer structure of the human cortex.
När vi ser en sadist, en man dömd till tio års fängelse för grov misshandel av ett oskyldigt barn, ett barn som plågades i timmar, dagar, veckor och månader innan han slutligen dog och sänktes i en sjö - vad ser de då?
En stackars oskyldig, missförstådd man, offer för omständigheter han inte rår över? Som inte alls gjort sig skyldig till de grymheter tingsrätten dömt honom för.
En man som bara de kan förstå och förlösa.
En man de kan "hjälpa".
En man som behöver dem.
Kaka söker maka. Sjukligt störda kvinnor dras tydligen till sjukligt störda män, och man får väl bara hoppas på att ingen av kvinnorna har barn.
Pinkerton added that the results from this study are further proof that secondhand smoke's effects on children are not minor, temporary or reversible. "This is the missed message about secondhand smoke and children," he said. "Parents need to understand that these effects will not go away. If children do not grow healthy lungs when they are supposed to, they will likely never recover. The process is not forgiving and the children are not going to be able to make up this loss later in life."
...In the new study, the researchers analyzed step-by-step how the alveolar cells' inner workings reacted to cigarette smoke. They found the normal orderly process of cell housecleaning had gone haywire.
In healthy people, cells live and die on a schedule. Programmed cell death, called apoptosis (a-pop-TOE-sis), is regulated by genes that increase or decrease various chemical reactions in the cell.
But in this study, when baby monkeys were exposed to cigarette smoke before and after birth, apoptosis went awry. Critical cellular controls regulating cell death turned off. Alveolar cells died twice as fast as they should have.
"If you are killing cells at a higher rate during a critical developmental stage, when they are supposed to be proliferating in order to create new alveoli, the lungs may never be able to recover," Pinkerton said.
Nehme Y. Tohme, a member of Parliament from the anti-Syrian reform bloc and the country’s minister for the displaced, said he had been told by Hezbollah officials that when the shooting stopped, Iran would provide Hezbollah with an “unlimited budget” for reconstruction.
"Without being hysteric, it is important to realize that the impact of global warming is not just about searing hot summers -- it is about water as a resource. It is about when and where it rains and how much we have to drink," said Pagani.
..
"In the PETM, because there were no sharp warm and cold fronts meeting to triggering rainfall, massive amounts of water got transferred from the tropics and sub-tropics to the arctic," said Pagani. "That drastically increased humidity and precipitation in the arctic. In turn, it led to increased river runoff that lowered the ocean salinity, changing its oxygen capacity and the plant life in the region. It also probably left the middle latitudes a lot dryer."
