Is Asperger’s Syndrome a Type of Autism?
History of Asperger’s syndrome Asperger’s syndrome or Asperger’s is a developmental disorder. Asperger’s is thought to be a similar but less severe form of autism. Asperger’s syndrome or Asperger’s is a developmental disorder. It is a type of autism spectrum disorder. People with Asperger’s have behavioral challenges and lack social and communication skills. Asperger’s is […]
Make the Diagnosis: Good That She Didn’t Ignore This
Presentation A 50-year-old woman with a long history of cigarette smoking asked her dentist about a white oral plaque that she noticed on the underside of her tongue. She thought it had been there for several months. It was not painful and didn’t seem to cause any other symptoms, but she was concerned it might […]
Zeroing in on the origins of Earth’s ‘single most important evolutionary innovation’: A new study shows oxygenic photosynthesis likely evolved between 3.4 and 2.9 billion years ago.
Some time in Earth’s early history, the planet took a turn toward habitability when a group of enterprising microbes known as cyanobacteria evolved oxygenic photosynthesis — the ability to turn light and water into energy, releasing oxygen in the process. This evolutionary moment made it possible for oxygen to eventually accumulate in the atmosphere and […]
Ancient DNA rewrites early Japanese history — modern day populations have tripartite genetic origin
Ancient DNA extracted from human bones has rewritten early Japanese history by underlining that modern day populations in Japan have a tripartite genetic origin — a finding that refines previously accepted views of a dual genomic ancestry. Twelve newly sequenced ancient Japanese genomes show that modern day populations do indeed show the genetic signatures of […]
Monkeypox Treatment, Outbreak History, Symptoms, Vaccine & Pictures
What is the history of monkeypox? Monkeypox has a relatively recent history. People first discovered it in monkeys in 1958, although a “vesicular disease in monkeys” was described in the 1860s. The disease, and eventually the causative virus, was named monkeypox because the lesions (pox) seen in monkeys developed like other known pox-forming diseases (pustules […]
Can Gargling Protect School Kids From COVID?
As the largest mass vaccination campaign in human history progresses, the landscape of immunity against SARS-CoV-2 within the U.S. is changing. The vaccine strategy that began with focused protection for some and rapidly expanded to protection for all, continues to serve as the crucial step in decoupling COVID-19 deaths from infections. Approximately 50% of our […]
Meet the Martian meteorite hunters
A team at the Natural History Museum (NHM), London is paving the way for future rovers to search for meteorites on Mars. The scientists are using the NHM’s extensive meteorite collection to test the spectral instruments destined for the ExoMars rover Rosalind Franklin, and develop tools to identify meteorites on the surface of the red […]
DNA reveals the evolutionary history of museum specimens
Museum specimens held in natural history collections around the world represent a wealth of underutilized genetic information due to the poor state of preservation of the DNA, which often makes it difficult to sequence. An international team, led by researchers from the University of Geneva (UNIGE) and the Museum of Natural History of the City […]
