Acoustically Actuated Microscopic Device Developed
Researchers at EPFL have developed remote-controlled, mechanical microdevices that, when inserted into human tissue, can manipulate the fluid that surrounds them, collect cells or release drugs. This breakthrough offers numerous potential applications in the biomedical field, from diagnostics to therapy.

Segmentation Clock Progresses More Slowly in Humans Than Mice
Scientists from the RIKEN Center for Biosystems Dynamics Research, European Molecular Biology Laboratory (EMBL) Barcelona, Universitat Pompeu Fabra, and Kyoto University have found that the “segmentation clock”—a genetic network that governs the body pattern formation of embryos—progresses more slowly in humans than in mice because the biochemical reactions are slower in human cells.

How Fruit Flies Keep Up With Climate Change
In a new study, scientists have found many genes responsible for setting fruit flies’ internal alarm clock and found that an imperceptibly slow development during dormancy is key to their rapid genetic adaption.

New Genetic System Can Halt or Eliminate Gene Drive in the Wild
Scientists at the University of California San Diego and their colleagues have developed two new active genetic systems that address risks associated with gene drives halting or eliminating them in the wild.

Structural Mechanism of Coronavirus Receptor Binding Revealed
The spike protein on the surface of the SARS-CoV-2 coronavirus can adopt at least ten distinct structural states, when in contact with the human virus receptor ACE2, according to research carried out by scientists at the Francis Crick Institute.

Study of Over 1 Million People Suggests Blood Type O May Protect Against COVID-19
In June, Technology Networks reported on some of the initial findings from personal genomics and biotechnology company 23andMe's COVID-19 genetic study. These results lent further evidence to earlier suggestions that an individual's blood type – determined by a gene known as ABO – may be associated with COVID-19 susceptibility. Now, 23andMe scientists have published results from the first four months of the study which has collected data from over 1 million research participants.

Shining Light on Photoconversion in Green Fluorescent Protein
Scientists from the Skolkovo Institute of Science and Technology (Skoltech), the Institute of Bioorganic Chemistry (IBCh RAS) and Lomonosov Moscow State University (MSU) undertook a detailed study on green-to-red photoconversion (light-induced conversion) of the Green Fluorescent Protein (GFP).

Imaging the ORC Complex Responsible for Genome Replication
Cold Spring Harbor Laboratory (CSHL) Professor & HHMI Investigator Leemor Joshua-Tor and colleagues published images of the human ORC in exquisite detail in eLife, showing how it changes shapes in dramatic ways as it assembles around DNA.

Researchers Discover a Way To Create Induced Tropoblast Stem Cells
An international collaboration involving Monash University and Duke-NUS researchers have made an unexpected world-first stem cell discovery that may lead to new treatments for placenta complications during pregnancy.

Largest Ever DNA Sequencing of Viking Skeletons “Rewrites” History
Invaders, pirates, warriors – the history books taught us that Vikings were brutal predators who travelled by sea from Scandinavia to pillage and raid their way across Europe and beyond. Now cutting-edge DNA sequencing of more than 400 Viking skeletons from archaeological sites scattered across Europe and Greenland will rewrite the history books.
