Australian doctors transplants first circulatory death human heart

Australian doctors transplants first circulatory death human heart

The St Vincent’s Hospital Heart Lung Transplant Unit has carried out the world’s first distant procurement of hearts donated after circulatory death (DCD). These hearts were subsequently resuscitated and then successfully transplanted into patients with end-stage heart failure Continue reading

Growing a blood vessel in a week

Growing a blood vessel in a week

The technology for creating new tissues from stem cells has taken a giant leap forward. Three tablespoons of blood are all that is needed to grow a brand new blood vessel in just seven days. Continue reading

Hidden truth about the health of homeless people

Hidden truth about the health of homeless people

As many as 4 million Europeans and 3•5 million Americans experience homelessness every year, and the numbers are rising. Homeless people “are the sickest in our society,” but just treating ill health might not be enough to help get people off the streets, according to a new two-part Series on homelessness in high-income countries, published in The Lancet Continue reading

Designer ‘barrel’ proteins created

Designer ‘barrel’ proteins created

Proteins are long linear molecules that fold up to form well-defined 3D shapes. These 3D molecular architectures are essential for biological functions such as the elasticity of skin, the digestion of food, and the transport of oxygen in blood Continue reading

Ancient Europeans intolerant to lactose for 5,000 years after they adopted agriculture

Ancient Europeans intolerant to lactose for 5,000 years after they adopted agriculture

By analysing DNA extracted from the petrous bones of skulls of ancient Europeans, scientists have identified that these peoples remained intolerant to lactose (natural sugar in the milk of mammals) for 5,000 years after they adopted agricultural practices and 4,000 years after the onset of cheese-making among Central European Neolithic farmers. The findings published online in the scientific journal Nature Communications (21 Oct) also suggest that major technological transitions in Central Europe between the Neolithic, Bronze Age and Iron Age were also associated with major changes in the genetics of these populations.

Mental rest and reflection boost learning, study suggests

Mental rest and reflection boost learning, study suggests

A new study, which may have implications for approaches to education, finds that brain mechanisms engaged when people allow their minds to rest and reflect on things they’ve learned before, may boost later learning. Scientists have already established that resting the mind, as in daydreaming, helps strengthen memories of events and retention of information. In a new twist, researchers at The University of Texas at Austin have shown that the right kind of mental rest, which strengthens and consolidates memories from recent learning tasks, helps boost future learning.

Measuring on ice: Researchers create ‘smart’ ice skating blade

Measuring on ice: Researchers create ‘smart’ ice skating blade

An ice skating blade that informs figure skaters of the stresses they are imposing on their joints has been developed by a group of researchers in the US. The small, lightweight device has been built to measure the force that a figure skater exerts on the ice when performing their repertoire of jumps and spins and could potentially be used by skaters and their trainers to avoid injuries, as well as inform the design of new skating boots. The instrumented blade has been presented today, 21 October, in IOP Publishing’s journal Measurement Science and Technology . Continue reading

Cystic Fibrosis lung infection: Scientists open black box on bacterial growth

Cystic Fibrosis lung infection: Scientists open black box on bacterial growth

Researchers from the University of Copenhagen have shown for the first time how bacteria can grow directly in the lungs of Cystic fibrosis patients, giving them the opportunity to get tremendous insights into bacteria behavior and growth in chronic infections. The study also discovered the bacterial growth in chronic lung infections among cystic fibrosis (CF) patients was halted or slowed down by the immune cells. The researchers discovered the immune cells consumed all the oxygen and helped “suffocate” the bacteria, forcing the bacteria to switch to a much slower growth. Continue reading

Tailored ‘activity coaching’ by smartphone

Tailored ‘activity coaching’ by smartphone

Today’s smartphone user can obtain a lot of data about his or her health, thanks to built-in or separate sensors. Researcher Harm op den Akker of the University of Twente (CTIT Institute) now takes this health monitoring to a higher level. Continue reading
