Flu viruses can use a second entry pathway to infect cells

Most influenza viruses enter human or animal cells through specific pathways on the cells' surface. Researchers at the University of Zurich have now discovered that certain human flu viruses and avian flu viruses can also use a second entry pathway, a protein complex of the immune system, to infect cells.

Study reveals how DDM1 protein suppresses 'jumping genes' in plants

International joint research led by Akihisa Osakabe and Yoshimasa Takizawa of the University of Tokyo has clarified the molecular mechanisms in thale cresses (Arabidopsis thaliana) by which the DDM1 (Decreased in DNA Methylation 1) protein prevents the transcription of "jumping genes."

Cryo-EM reveals structural dynamics of RNAP-DNA interactions during transcription initiation

Every living cell transcribes DNA into RNA. This process begins when an enzyme called RNA polymerase (RNAP) clamps onto DNA. Within a few hundred milliseconds, the DNA double helix unwinds to form a node known as the transcription bubble, so that one exposed DNA strand can be copied into a complementary RNA strand.

New study reveals how RNA polymerase opens the transcription bubble in real time

Every living cell transcribes DNA into RNA. This process begins when an enzyme called RNA polymerase (RNAP) clamps onto DNA.

Johns Hopkins researchers discover how epilepsy drug modulates brain activity

By super cooling a molecule on the surface of brain cells down to about minus 180 degrees Celsius -; nearly twice as cold as the coldest places in Antarctica -; scientists at Johns Hopkins Medicine say they have determined how a widely-used epilepsy drug works to dampen the excitability of brain cells and help to control, although not cure, seizures.
