Cells starved of oxygen and nutrients condense their DNA

Scientists at the Institute of Molecular Biology (IMB) have been able to see, for the first time, the dramatic changes that occur in the DNA of cells that are starved of oxygen and nutrients. This starved state is typical ...

MouthLab: Patients' vital signs are just a breath away

Engineers and physicians at the Johns Hopkins University School of Medicine have developed a hand-held, battery-powered device that quickly picks up vital signs from a patient's lips and fingertip. Updated versions of the ...

New probe can monitor shock from hemorrhages without drawing blood

It's inefficient to periodically draw blood from someone's neck to check oxygen levels, especially when that person is in an intensive care unit for massive blood loss. Yet the invasive procedure is currently the go-to method ...

Starved-out bacteria aid in wastewater treatment

Blue blood on ice: How an Antarctic octopus survives the cold

An Antarctic octopus that lives in ice-cold water uses an unique strategy to transport oxygen in its blood, according to research published in Frontiers in Zoology. The study suggests that the octopus's specialized blood ...

Scientists develop compact medical imaging device

Scientists at the MIRA research institute, in collaboration with various companies, have developed a prototype of a handy device that combines echoscopy (ultrasound) with photoacoustics. Combining these two medical imaging ...

Study helps prevent rhino deaths during relocation

Wildlife experts lose one to two black rhinoceros each year from anesthesia complications when they capture and relocate the animals. That's 1 to 2 percent of the black rhinos that are moved annually, but with only 5,000 ...
