Imbalanced electrical charges in biomolecular condensates spark redox reactions

The human body relies heavily on electrical charges. Lightning-like pulses of energy fly through the brain and nerves and most biological processes depend on electrical ions traveling across the membranes of each cell in our body.

Ethanol vapor inhalation can disable influenza A virus in mice

Inhaling low concentrations of ethanol vapor can disable the influenza A virus in mice, without harmful side effects, says a new study by scientists at the Okinawa Institute of Science and Technology (OIST). The scientists believe it may also treat similar viruses such as the one that causes Covid-19.

How inert, sleeping bacteria spring back to life

Solving a riddle that has confounded biologists since bacterial spores -; inert, sleeping bacteria -; were first described more than 150 years ago, researchers at Harvard Medical School have discovered a new kind of cellular sensor that allows spores to detect the presence of nutrients in their environment and quickly spring back to life.

Study reveals survival time of SARS-CoV-2 in wastewater: Implications for public health

Study investigated the survival of SARS-CoV-2 in three wastewater matrices - filtered and unfiltered raw wastewater, and secondary effluent. The time required for inactivation of 90% of SARS-CoV-2 was observed to be 10.4, 10.8, and 18.3 hours for unfiltered raw, filtered raw, and secondary effluent, respectively.

Researchers develop a backpack-based myeloid cell therapy for MS patients

Multiple sclerosis (MS) is a devastating autoimmune disease that destroys the protective myelin covering around nerves, disrupting communication between the brain and body, and causing patients' ability to move and function to progressively decline.
