First-of-a-kind blood test paves way for early Parkinson’s diagnosis

Posted on by

A new test that focuses on biomarkers in blood serum has shown promise as a way of detecting Parkinson's

With no way of completely curing the condition, earlier diagnosis of Parkinson’s disease can have profound impacts on treatment options and a patient’s quality of life. Scientists are making inroads when it comes to picking up the tell-tale signs of the disease’s onset, and a new first-of-a-kind study has demonstrated how these might be revealed through an inexpensive blood test that has shown a high degree of accuracy in early trials.

Were dinosaurs warm- or cold-blooded? Clues lie in their breath and bones

Posted on by

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 found the answer for different groups of dinosaurs, by analyzing metabolic markers from their breath … Continue reading Were dinosaurs warm- or cold-blooded?

Wearable simultaneously measures alcohol, lactate and glucose levels

Posted on by

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.Continue ReadingCate… Continue reading Wearable simultaneously measures alcohol, lactate and glucose levels→

Light-sensitive “tattoo” sensor could measure substances in the blood

Posted on by

When treating patients for certain conditions – including COVID-19 – 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-born… Continue reading Light-sensitive “tattoo” sensor could measure substances in the blood→

Landmark study finds first biomarker to detect babies at risk of SIDS

Posted on by

Sudden infant death syndrome (SIDS) is one of leading causes of infant death and until now researchers have not been able to identify any specific physiological factor that may make a baby more vulnerable. A team of researchers in Australia have now id… Continue reading Landmark study finds first biomarker to detect babies at risk of SIDS→

New blood test predicts type 2 diabetes risk in people of normal weight

Posted on by

Obesity is by far the most common risk factor for type 2 diabetes, but one in five people diagnosed with the disease are of a normal weight. A new test promises a novel way to estimate diabetes risk by looking for patterns of molecules in blood samples… Continue reading New blood test predicts type 2 diabetes risk in people of normal weight→

Landmark trial finds donating blood lowers PFAS “forever chemical” levels

Posted on by

A world-first Australian clinical trial has found regular blood or plasma donations can reduce levels of toxic PFAS chemicals in the blood by up to 30 percent. The trial is the first to find an effective intervention that reduces levels of the substanc… Continue reading Landmark trial finds donating blood lowers PFAS “forever chemical” levels→

Risk of serious blood clot events spike in the months after COVID-19

Posted on by

New observational research out of Sweden has tracked more than one million COVID-19 cases for months after their acute illness in order to determine how the disease influences subsequent risk of blood clots. The findings indicate COVID-19 significantly… Continue reading Risk of serious blood clot events spike in the months after COVID-19→

Body alarm for blood loss can be reset to stop cardiovascular collapse

Posted on by

In the event of blood loss, the human body has defense mechanisms that kick into gear to protect it from the worst outcomes, but they can only keep up the fight for so long. Scientists have pinpointed a set of neurons that regulate this process, which … Continue reading Body alarm for blood loss can be reset to stop cardiovascular collapse→
