Immune cell plays unexpected role in autoimmune disease

A new study finds that dendritic cells play a key role in amplifying autoimmune disease, specifically systemic lupus erythematosus (SLE). The research suggests that depleting dendritic cells may be a potential therapeutic strategy for treating SLE and potentially other autoimmune diseases.

When the brain knows no fear

A new study on a woman without an amygdala, a key structure in generating fear reactions, reveals that humans also lack this function. Despite encountering traumatic events, she experiences little to no fear, while still feeling other emotions like happiness and sadness.

Computer memory takes a spin

Researchers at the University of Utah have successfully stored information in atomic nuclei for 112 seconds, a major breakthrough towards developing faster quantum computers. The new technique uses magnetic 'spins' in the centers of atoms to store and read data electronically.

London: The tuberculosis capital of Europe

The UK is experiencing a resurgence of tuberculosis, with London accounting for over 40% of all TB cases. The disease is concentrated in high-risk groups, including migrants, homeless people, and prisoners. Experts call for urgent recommendations to be implemented to control the spread.

Scientists identify the largest network of protein interactions related to Alzheimer's disease

Researchers at IRB Barcelona discovered 200 new protein interactions that could be linked to Alzheimer's disease, bringing the total number of interactions to 6000. The study reveals new molecular mechanisms, including oxidative stress and inflammation, which may play a role in the development of the disease.

Medical robotics to improve heart surgery

Researchers are developing a robotic system that combines real-time magnetic resonance imaging (MRI) with a highly flexible robotic device to perform cardiothoracic surgeries on beating hearts. This minimally invasive approach aims to increase precision and reduce trauma, leading to faster recovery times.

Adjuvanted HINI vaccine induces a more rapid and stronger immune response than whole-virus vaccine, particularly in young adults

A head-to-head trial found that the adjuvanted split-virus vaccine achieved a more rapid and stronger immune response than the whole-virus vaccine. In young adults, a single dose of the adjuvanted vaccine induced early seroprotection within one week, suggesting potential for reduced dosing frequency.

UTMB researchers find medical educational changes dramatically improves academic achievements

A comprehensive medical education reform significantly improves failure rates of the Step 1 licensing exam and increases graduation rates among underrepresented minority medical students. The integrated curriculum shows a nearly 70% decrease in failure rates and a 94% decrease in failure rates for African American students.

Better spaces for older people

The 'Older People's Use of Unfamiliar Space' project examines strategies used by older people to find their way in unfamiliar spaces. Designing outdoor spaces that are more easily navigable and walkable is crucial in reducing stress levels, with buildings and landmarks serving as key navigational aids.

Mount Sinai researchers develop mouse model to help find how a gene mutation leads to autism

Mount Sinai researchers create mouse model to investigate the impact of a single SHANK3 gene mutation on nerve cell communication and social behavior. The study identifies impaired communication and altered plasticity in nerve cells, providing critical insight into the development of autism spectrum disorders.

University of Miami Rosenstiel School names Kieran T. Bhatia 2010 Alumni Fellow

Kieran T. Bhatia, a meteorology and physical oceanography doctoral student, has been awarded the 12th annual Alumni Fellow at the University of Miami's Rosenstiel School. The fellowship provides tuition and stipend support for his graduate career. Bhatia is working on research related to hurricane dynamics and development.

Extinctions, loss of habitat harm evolutionary diversity

A recent study, led by Hélène Morlon, has found that evolutionary diversity is more sensitive to extinctions or habitat loss than previously thought. The researchers built an evolutionary tree tracing plant species back to their common ancestor and applied mathematical approaches to consider the impact of geographic separation on phylo...

New study suggests almonds may help reduce risk of type 2 diabetes and heart disease

A new study suggests that consuming an almond-enriched diet can improve insulin sensitivity and decrease LDL-cholesterol levels in individuals with prediabetes. The study found significant improvements in insulin levels, homeostasis model analysis for insulin resistance, and clinically significant reductions in LDL-cholesterol.

Road to a safer future

The E! 4160 VICATS project has developed an innovative surveillance system that uses computer algorithms to assess real-time traffic conditions. The system can operate autonomously, gathering information 24/7 without human intervention, and has shown promising results in various scenarios, including tunnels, bridges, and crossroads.
