Tiny wireless implant detects oxygen deep within the body

Engineers have created a tiny wireless implant that can provide real-time measurements of tissue oxygen levels deep underneath the skin. The device, which is smaller than the average ladybug and powered by ultrasound waves, could help doctors monitor the health of transplanted organs or tissue and provide an early warning of potential transplant failure.

Suppression of COVID-19 waves reflects time-dependent social activity not herd immunity

Scientists developed a model showing that a fragile, temporary state of immunity emerged during the early epidemic but got destroyed as people changed their social behaviors over time, leading to future waves of infection.

ER visits for suicidal behavior declined during the first 8 months of pandemic Michigan study finds

While people may expect suicide rates to rise during a worldwide crisis such as the COVID-19 pandemic, a new study suggests the onset of the pandemic and state of emergency executive orders likely did not increase suicide-related behavior in the early months of the outbreak. The report found that emergency room visits related to suicide attempt and self-harm decreased by 40 percent during the first eight months of Michigan's lockdown.

Air pollution may affect severity and hospitalization in COVID-19 patients

Patients who have preexisting respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD) and live in areas with high levels of air pollution have a greater chance of hospitalization if they contract COVID-19, according to new research.

Get your head in the game -- One genes role in cranial development

Researchers have found that certain cells in mouse craniums respond to increased expression of a gene called Dlx5 during early stages of embryonic development. They observed that a layer of these cells formed more bone and cartilage in mice engineered with high Dlx5 levels. Their interesting results provide crucial information for the mechanistic role of this gene in cell fate during cranial development.

A mothers fat intake can impact infant infectious disease outcomes

A team of researchers has determined that the type of fats a mother consumes while breastfeeding can have long-term implications on her infant's gut health. Their study suggests that the type of fat consumed during breastfeeding could differentially impact an infant's intestinal microbial communities, immune development and disease risk.
