Start codons in DNA may be more numerous than previously thought

Start codons in DNA may be more numerous than previously thought


FTA: "We kind of all collectively asked ourselves: had anyone ever looked?" said Hecht. A further review of available literature on the topic indicated that the answer was no.

A good point for those who think that 'Science is settled'.  If its settled, it's not science.
Sometimes, you have to ask the question..."What if our understanding is wrong?"  !!


More FTA: "We thought we knew the rules, but it turns out there's a whole other level we need to learn about. The grammar of DNA might be even more sophisticated than we imagined."

The leaning tower of San Francisco sinking faster than previously known.

A new formulation...' perhaps faster than previously known'...  What an ambiguous way to say this.


The leaning tower of San Francisco sinking faster than previously known.


FTA: ... "The luxury high-rise has sunk about 16 inches and is also tilting. Engineers have estimated the building is still sinking at a rate of about 1-inch per year."

Greek and Chinese Trade: "This is far earlier than we formerly thought."

Here is an interesting link

.
The DNA evidence comes from remains from sites in the Xinjian province dating to the time period of the first emperor. They show that Chinese and Europeans were likely encountering each other at that early date. “We now have evidence that close contact existed between the first emperor’s China and the west before the formal opening of the Silk Road. This is far earlier than we formerly thought,” says Li Xiuzhen, Senior Archaeologist at the museum that houses the terra cotta warriors. “We now think the Terra cotta Army, the acrobats and the bronze sculptures found on site, have been inspired by ancient Greek sculptures and art.”
... though the Silk Road between China and Europe was formally established in the 3rd century A.D., Chinese accounts claim Roman traders arrived well before that. As she points out, during the rule of the First Emperor of Rome, Romans were already wearing Chinese silk.

Features on the Moon are Younger TPT

From this article:

Impact! New Moon Craters Are Appearing Faster Than Thought


These new findings also suggest that a number of young features on the moon's surface, such as recent volcanic deposits, "may in fact be even a bit younger than previously thought," Speyerer said.

A-final-blow-to-myth-of-how-people-arrived-in-the-Americas

From the Christian Science Monitor

FTA: For decades, archaeologists thought they knew how the story went: Humans migrated from Siberia to Alaska over the Bering land bridge during the last Ice Age, 

New research published in Nature and
 
Evidence from Bison Biology in PNAS

Regarding the ice-free corridor after the last ice age FTA:

 "...we both also agree that the first hard [archaeological] evidence in the corridor when it finally opens is post-Clovis in age, and likely from people moving north and not south."

And relatively rare for stories like this; no use of the terms 'Than Previously thought' or 'more research is needed'.

"These results were a great surprise to us,"

FTA:
"Native Americans may have a more complicated heritage than previously believed."

 Nearly one-third of Native American genes come from west Eurasian people linked to the Middle East and Europe, rather than entirely from East Asians as previously thought, according to a newly sequenced genome.

...
Willerslev believes the discovery provides simpler and more likely explanations to long-standing controversies related to the peopling of the Americas.
