A cave in a remote part of Mexico was visited by humans around 30, years ago — 15, years earlier than people were previously thought to have reached the Americas. Painstaking excavations of Chiquihuite Cave, located in a mountainous area in northern Mexico controlled by drugs cartels, uncovered nearly stone tools from a small section of the high-altitude cave. Archaeological analysis of the tools and DNA analysis of the sediment in the cave uncovered a new story of the colonisation of the Americas which now traces evidence of the first Americans back to 25,, years ago.

The results, which have been published in Nature today July 22 , challenge the commonly held theory that the Clovis people were the first human inhabitants of the Americas 15, years ago. Professor Willerslev said: “For decades people have passionately debated when the first humans entered the Americas. Chiquihuite Cave will create a lot more debate as it is the first site that dates the arrival of people to the continent to around 30, years ago — 15, years earlier than previously thought.

These early visitors didn’t occupy the cave continuously, we think people spent part of the year there using it as a winter or summer shelter, or as a base to hunt during migration. This could be the Americas oldest ever hotel. The year long research project raises more questions about the early humans who lived in the Americas than it solves. Dr Ardelean said: “We don’t know who they were, where they came from or where they went. They are a complete enigma. We falsely assume that the indigenous populations in the Americas today are direct descendants from the earliest Americans, but now we do not think that is the case.

There could have been many failed colonisations that were lost in time and did not leave genetic traces in the population today. Chiquihuite Cave is a high-altitude site, metres above sea level.

We just archived our first paleoclimate dataset that reconstructs climate conditions based on bat guano. This new data provides important insights into the Medieval Warm Period from about to AD and the Little Ice Age from roughly to AD for locations with previously sparse proxy data availability. Within this cave is an area called the Circular Room, where a large colony of bats has lived for many generations.

Bat guano is an important component of the Mammoth Cave Mammoth Cave It is important to note that all 14C dates are on were left in the smallest sized.

October 10, To help determine forest restoration goals in Costa Rica, postdoctoral scholar Rachel Reid will travel to Central America this winter to explore a cave long inhabited by bats. What did the Costa Rican landscape look like thousands of years ago? A team of Saint Louis researchers is hoping that bat guano will help them answer that question.

Armed with peat borers and insect traps, a team of researchers led by Rachel Reid, a postdoctoral scholar in the Department of Anthropology, will travel to Central America this winter to explore a cave long inhabited by bats. The scientists plan to use biochemical signatures preserved in bat guano to understand how vegetation coverage has changed over the past several thousand years. Instead, Reid’s team will look at biochemical signatures preserved in caves, which naturally shield their contents from much of the rainforest’s heat and humidity.

Their field site, Bajo los Indios Cave, has housed a type of insect-eating bat known as Parnell’s mustached bat Pteronotus parnellii for millennia — which means the cave also has a cache of bat guano, the remains of insects digested by the bats, dating back thousands of years. The chemical makeup of insects’ exoskeletons is impacted by the vegetation they eat: If an insect eats corn, grass, or other open-habitat plants which carry out photosynthesis via the C4 pathway , it will have a carbon isotopic signature that reflects C4 photosynthesis.

If the insect eats rainforest vegetation which uses the C3 photosynthesis pathway , its carbon isotopic signature will instead reflect C3 photosynthesis.

Benjamin Horton remembers being in Southeast Asia just months after the devastating Indian Ocean tsunami. Horton, who studies sea levels at Rutgers University and Nanyang Technological University , was just one of dozens of researchers who came in search of answers: Had this happened before? Would it happen again? The answers were certainly not to be found in written records or seismometer data. In the short time such data have existed for the Indian Ocean, no one had ever recorded an earthquake capable of sending such a huge wall of water crashing into the coast.

The tsunami in was so deadly because it was so unexpected. The answer, if scientists were to find it, would probably be in sand. Tsunamis pick up sand from the depths of the ocean floor, depositing it on land as the waters recede. Low-lying coastal plains are good places to look. So are lagoons or mangrove swamps that trap sand. A number of such sites around the Indian Ocean have allowed scientists to begin piecing together a fragmentary history of Indian Ocean tsunamis.

To that, Horton and his colleagues now add an exciting new find: a coastal cave in Indonesia containing layers of sand left by tsunamis all the way back to the Stone Age 7, years ago.

We discovered a coronavirus similar to the covid-19 virus 7 years ago

While several of our caves are open as of June 1, , we ask that you please visit safely and familiarize yourself with the latest COVID guidelines on our Keeping Visitors Healthy page. Limestone is a rock laid down as calcium deposits on the bottoms of shallow oceans, millions of years ago. When exposed to rain and flowing water, limestone erodes leaving channels and cavities.

These cavities can stretch for miles along the original bedding planes or joints in the beds.

Coronavirus Could Be a ‘Chimera’ of Two Different Viruses, Genome Analysis Suggests

They smell strangers when they approach. So we always know when there are intruders. That would have been useful in the years of Fiji’s vicious tribal wars because the huge cave Ratu was taking us to see was the place where the people of his Tau village have sought shelter for hundreds – possibly thousands – of years.

material was dated using the 14C AMS method; 13 dates from 6, to 14C yr BP (yr BP) were obtained. Holocene bat fauna are cave thanato- coenoses.

Researchers from the Wuhan Institute of Virology were the first to link SARS and bats for the first time during a study in after raiding a cave in Yunnan province. They took samples of wild bat droppings and found they were carriers of hundreds of different types of coronaviruses. The virologist who led the research, Shi Zhengli, has now revealed one of the strains is almost identical to the one currently ravaging China.

COVID has killed more than 1, people and infected over 45, worldwide since the epidemic began in late December. But they have been unable to pin down exactly which animal first passed it on. Bats are known carriers of coronaviruses so they have been highlighted as a possible culprit, along with snakes and pangolins. The exact location of the cave in the study has been kept under wraps, but it’s said to be somewhere in Yunnan, at least 1,miles 1,km from Wuhan.

Professor Shi and her team made the unusual discovery that 3 per cent of people living near the Yunnan cave had developed immunity to the viruses. She said this proved the strains can and have infected humans in the past, and that immunising people against them was possible. Horseshoe bats were one of four bat species studied over a five-year period after Professor Shi’s team returned to the cave for a second study in The scientists cross-referenced the genome sequence of COVID with the results and found it was a 96 per cent match to a virus found in the droppings of horseshoe bats.

Horseshoe bats are known carriers of the viruses and scientists believe they may be the culprit for the recent outbreak. China hopes the killer virus, which has claim claimed more than 1, lives shown will be curbed by April.

Toy bats mark the entrance to the geography luminescence lair. Image: Megan Lambert. Hidden behind a two-way darkroom door decorated with stuffed bats toys, not taxidermy , Libby Griffin, Jordan Bryce, and Maureen Eyers analyze grains of sand in near darkness. Bryce explains the process: Grains of sand are exposed to light, and the electrons recombine at the centres, giving off excess energy as luminescence.

The machine measures how much luminescence the particles give off, in order to know how many electrons were in a sample. Students dig for samples in the field, then take the sand back to sift for data. Image: Libby Griffon. The machine prints out a graph, and with data analysis geologists are able to calculate the age and the last time they were exposed to sunlight.

Griffin notes that quartz lets off a small amount of light, making it difficult to track data. They use the liquid lithium metatungstate LMT to separate the two further. The grains are then treated with an acid to smooth over any erosion or impurities, and are made similar sizes to keep the data consistent. The data from coastal BC — places like Haida Gwaii and Quadra Island — can be collected into a larger pool to help track tides and climate over thousands of years.

Griffin says that her work at UFV started with a Friday morning class she shared with Eyers — their prof and now supervisor, Olav Lian, opened up student positions for lab work.
