Tel Aviv University scientists print first 3D heart using patient's biological materials

Researchers successfully engineered and printed a 3D vascularised engineered heart with cells, blood vessels, ventricles, and chambers that matches the immunological, cellular, biochemical, and anatomical properties of the patient. The use of native patient-specific materials is crucial to eliminating implant rejection risks.

Climate change could undermine children's education and development in the tropics

A new study suggests that extreme heat and precipitation in early childhood can lead to lower educational attainment, even among better-off households. The research found that climatic conditions affect education negatively in multiple ways, particularly in Southeast Asia and West and Central Africa.

Genetic analysis has potential to transform diagnosis and treatment of adults with liver disease of unknown cause

A new study published in the Journal of Hepatology reports that whole-exome sequencing (WES) can diagnose the genetic cause of liver disease in a significant proportion of adult patients. The analysis identified four monogenic disorders in five unrelated adults, enabling new treatment options and shedding light on underlying molecular ...

Same-sex marriage legalization associated with reduced anti-gay bias in the US

A new study by McGill University researchers found that state legislation played a significant role in reducing anti-gay bias in the US. By analyzing data from over 1 million respondents, the team discovered that laws supporting same-sex marriage led to a sharp decline in biases, with the effect being roughly double the previous rate.

'Flight recorder' of rocks within the Earth's crust

Daniela Rubatto's research provides a new way to connect minerals' ages to their formation conditions, reconstructing the speed and duration of rock travel within the Earth's crust. Her innovative method uses an ion microprobe to extract valuable information from minerals, contributing to better understanding geological processes.

New study reveals 'silence' around suicide in young people

A new study by the University of Stirling has identified a silence around suicidality among children and young people, with many feeling they cannot access help or are not listened to by healthcare professionals. The research emphasizes the importance of using explicit language, such as 'suicide,' in mental health conversations.

Kin relationships in megalithic burial sites

A study found kin relationships among people buried in Neolithic megalith tombs, indicating a societal role for these enigmatic structures. The genomic data revealed affinity to farming groups with past admixture with hunter-gatherer groups, highlighting a previously unknown role for megaliths in Neolithic societies and families.

Engineering 'hairpins' increases CRISPR accuracy

Biomedical engineers at Duke University developed a method to improve CRISPR accuracy by adding a short tail to the guide RNA, creating a 'lock' that prevents off-target activity. The approach increases accuracy by an average of 50-fold across five different CRISPR systems.
