The Real Science Behind
The Odd Shelf
A Parks Canada research team is en route to the underwater wrecks of Sir John Franklin's ships in an effort to uncover more truths of what happened on the infamous and ill-fated expedition to find the Northwest Passage.
This year's archeological exploration plan of the HMS Erebus and HMS Terror that were lost for nearly 170 years is being called the "largest, most complex underwater archeological undertaking in Canadian history" by government officials in a public announcement Friday.
The truth was unavoidable. My beloved father, who died in a car accident when I was 23, had not been my biological father.
This discovery led me deep into a world I had known nothing about: the history, science and psychological underpinnings of assisted reproduction. I have spent the past few years piecing together the story of how I came to be, the truth of where (and who) I come from–and the ways in which my identity was scrupulously hidden from me.
Underwater archaeologists have finished their latest research trip to the wreck of the HMS Erebus, a ship abandoned in the Canadian Arctic 170 years ago during the ill-fated Franklin expedition.
Harsh weather conditions hampered this month's mission. Divers could not enter Sir John Franklin's cabin, where they had hoped to find documents or the ship's logs preserved in icy water that might explain the tragic fate of the ship.
The archaeologists did, however, bring nine more artifacts to the surface for conservation, including a ceramic pitcher and an artificial horizon used for navigation from an officer's cabin on the lower deck.
In the last seven days, genealogical sleuthing techniques that are old to a handful of genealogists but new to most law enforcement have led to arrests in Washington State and Pennsylvania and unearthed a lead in a 37-year-old murder in Texas. All three cases were only revived when crime scene DNA was uploaded to GEDMatch, the same open-source ancestry site used in the Golden State killer case.
Neuroscientists have long believed that memories are stored in the synapses, or junctions between the brain’s neurons. But UCLA neurobiologist David Glanzman subscribes to a different theory: the key to at least some memory storage, he thinks, is RNA, the cellular “messenger” that makes proteins and transmits DNA’s instructions to other parts of the cell.
The most important set of genetic instructions we all get comes from our DNA, passed down through generations. But the environment we live in can make genetic changes, too.
Last year, researchers discovered that these kinds of environmental genetic changes can be passed down for a whopping 14 generations in an animal – the largest span ever observed in a creature, in this case being a dynasty of C. elegans nematodes (roundworms).
The hunt for HMS Erebus and HMS Terror was tough enough.
Now Parks Canada underwater archeologists are sorting out just how they will try to unlock the clues to the Franklin Expedition mystery that may be hidden in the wrecks of the reinforced British warships that lie in the icy waters of Nunavut.
The long-lost ship of British polar explorer Sir John Franklin, HMS Terror, has been found in pristine condition at the bottom of an Arctic bay, researchers have said, in a discovery that challenges the accepted history behind one of polar exploration’s deepest mysteries.
Their latest results reveal that descendants of people who survived the Holocaust have different stress hormone profiles than their peers, perhaps predisposing them to anxiety disorders. This finding echoes the results of many other human epigenetic studies that show that the effects of certain experiences during childhood and adolescence are especially enduring in individuals and sometimes even across generations.
One of the most famous ships lost in the 19th century has been located in the Arctic, the Canadian government announced Tuesday, prompting Prime Minister Stephen Harper to declare that "one of Canada's greatest mysteries" has been solved.
