In one species of ants, workers duel to establish new leadership after the death of their queen. While these sparring matches stretch for more than a month, changes in behavior and gene expression in the first three days of dueling can accurately predict who will triumph, according to a New York University study published in the journal Genes & Development. ....

One Year In: Diagnostics

HMS Professor of Pathology, Brigham and Women’s Hospital
Core Faculty-Wyss Institute

HM News: One year in, where do we stand with diagnostics compared to where we were last year?
Walt: There’s been a huge amount of progress with diagnostics. At the beginning, what the public and perhaps many in the field didn’t fully realize was the gargantuan amount of testing that’s required to keep a global pandemic in check. We needed on the order of three times the total installed diagnostic testing capacity in the world at the time.
There were a lot of frustrations with respect to how fast things came online. But you have to understand, there weren’t any diagnostic tests for COVID-19 back when the pandemic hit. The fact that we even had molecular tools like RT-PCR and reagents to detect the virus is a testament to how much science and technology have advanced over the past several decades. ....

An international team of scientists has sequenced DNA from mammoth teeth that is at least a million years old, if not older. This research, published today in Nature, not only provides exciting new insight into mammoth evolutionary history, it reveals an entirely unknown lineage of ancient mammoth.

T. rex in popular imagination, but it is, in fact, one of the last mammoth species to have evolved, and it’s only one of various, sometimes odd-looking species of large, tusked animals belonging to the order Proboscidea. Mammoths are believed to have originated in Africa approximately 5 million years ago, with populations traveling north into what is now Eurasia and eventually moving into North America. We still have much to learn about these ancient ....

Published on: 02-09-2021
Public health officials have long touted widespread testing as one of the best ways to control the COVID-19 pandemic and save lives. In keeping with this guidance, La Sierra University in Riverside, California, United States, is bolstering its disease detection efforts with the rollout of new rapid-test equipment.
The university’s Student Wellness Services department, on January 13, 2021, deployed a rapid point-of-care PCR Cepheid GeneExpert Express molecular testing system. It will function in conjunction with a saliva-based screening process developed in the summer of 2020 by virologist Arturo Diaz. He studies positive-strand RNA viruses, of which the SARS-CoV-2 virus is a member. SARS-CoV-2 is the virus that causes the illness named COVID-19. ....
