Dinosaurs sit at the crossroads between reptiles and birds, leading scientists to debate whether they were warm- or cold-blooded. A new study may have the answer for different dinosaurs by analyzing metabolic markers from their breath in their bones.
-
While we've already seen skin-worn patches that can detect individual substances in the bloodstream, a new one goes considerably further. It simultaneously measures glucose, alcohol and lactate, and could have multiple applications.

When treating patients for certain conditions, it's important to monitor their blood oxygen levels. A new sub-dermal photosensitive sensor provides a new means of doing so, plus it could one day be used to measure other blood-borne substances.

Sudden infant death syndrome (SIDS) is one of leading causes of infant death and a team of researchers in Australia have now identified the first blood biomarker linked to brain arousal that could potentially be used to identify infants most at risk.

One in five people diagnosed with type 2 diabetes are of a normal weight. A new test could help identify such people by looking for patterns of molecules in blood samples that correspond with obesity-related metabolic changes, regardless of weight.

A world-first clinical trial has found blood or plasma donations can reduce levels of toxic PFAS chemicals by up to 30 percent. The trial is the first to find an effective intervention that reduces blood levels of substances known as “forever chemicals”.

New research has tracked more than one million COVID-19 cases after their illness and found a person’s risk of blood clotting events such as deep vein thrombosis and pulmonary embolism significantly increase in the months after infection.
-
Scientists have pinpointed a set of neurons that regulate the body's response to severe blood loss, expanding our understanding of how brain pathways control blood pressure and opening up a new approach to preventing cardiovascular collapse.
-
Early in the pandemic doctors began tracking the link between COVID-19 severity and blood type. Now researchers have validated those observations, finding several blood proteins are causally linked to an increased risk of hospitalization and death.
-
People who are using blood-thinning medications regularly have to check if their dosage needs adjusting. And while doing so currently involves lab tests or expensive home systems, a simple smartphone-based setup may soon be able to perform the task.
-
New research has found that during a six-month stay on the International Space Station, astronauts were destroying 3 million red blood cells every second. That's 54 percent more than the 2 million our bodies destroy and replace every second on Earth.

Cancer treatments have better outcomes if the disease is caught early. A new Oxford study demonstrates an experimental blood test that shows promise in detecting a variety of cancers in patients, and even whether or not they’ve spread.
