Italy: Ongoing hepatitis A virus outbreak among men who have sex with men is linked to current outbreaks in Europe

A study found that the Italian outbreak is predominantly caused by strains linked to recent European outbreaks, highlighting the risk of acute HAV infection via sexual transmission in high-risk groups like MSM. The study also emphasizes the importance of hepatitis A vaccine coverage and awareness campaigns for prevention.

Protein moonlighting

Researchers at UCSB discovered that syntaxin 3S, a soluble form of SNARE protein, regulates gene expression in the nucleus, potentially playing a role in cancer progression. This finding opens up a new field of research into the moonlighting properties of proteins.

New study finds genetic evidence that magnetic navigation guides loggerhead sea turtles

A new study by UNC-Chapel Hill biologists found that loggerhead sea turtles genetically similar to one another nest on beaches with similar magnetic fields. The research implies that turtles can mistakenly nest at different beaches with similar magnetic fields, even if it's geographically far away from their hatching beach.

Art is in the eye of the beholder

A study published in Acta Psychologica found that people's personality traits influence their eye movements when viewing abstract artwork. Volunteers who tended towards neuroticism spent more time looking at the left side of images, while those with schizophrenia-like traits looked less often at the top.

The fewer the deadlier

Researchers discovered that HTLV-1 survives by evading immune surveillance through transient Tax expression in infected cells. This unique strategy allows the virus to maintain a population of infected leukemic cells, making it a potential target for new therapies.

Newly identified gene mutation results in intellectual disability and developmental delay

Researchers at Cold Spring Harbor Laboratory have discovered a genetic mutation associated with intellectual disability, developmental delays, autism spectrum disorder, and congenital cardiac anomalies. The mutation, in the NAA15 gene, is linked to Ogden syndrome, a more severe condition also caused by a mutation in the NAA10 gene.

Research shows how genetics can contribute for advances in 2G ethanol production

Researchers have identified key genes involved in enzymatic degradation of sugarcane biomass by three fungal species. The study, supported by FAPESP, provides insights into the genetic mechanisms controlling enzyme secretion and expression, paving the way for more efficient biomass breakdown and production of biofuels.

Complexity, fidelity, application

Researchers in UCSB/Google group aim to demonstrate quantum supremacy with superconducting qubits, overcoming challenges of decoherence and error correction. Their goal is to build a qubit system capable of exploring complex states efficiently, enabling applications in condensed matter physics, chemistry, and materials.

Overestimated mutation rate

Researchers at ETH Zurich found that initial estimates of Ebola's genome change rate were due to biased computer models and limited virus sample data. The team's new calculations show a slower, more accurate mutation rate over time.

One string to rule them all

Scientists have engineered an extremely low loss nanostring that vibrates for minutes with a period of a microsecond, allowing them to 'hear' the sound of photons in a laser beam. The researchers hope to use this technology to detect weak light forces and potentially cool mechanical objects to absolute zero.

Punjab, India: Mass treatment of a population with chronic hepatitis C infection produces high rates of cure

A large-scale study in Punjab, India found that mass treatment of chronic hepatitis C infection using decentralized care and generic DAAs resulted in high cure rates among almost 20,000 individuals. The study validated the efficacy and safety of this approach, with over 90% of patients achieving sustained virological response.

Immune-engineered device targets chemo-resistant lymphoma

Researchers at Cornell University developed a device that exposes human lymphomas to fluid flow similar to that in the lymphatics and parts of the lymph node. The team found that certain subsets of DLCBL lymphoma respond differently to fluid forces, regulating expression levels of adhesion proteins known as integrins and B-cell receptors.

Understanding barriers to mental health care for urban black men who experience trauma

A recent study from the University of Pennsylvania School of Nursing explores how injured black men in Philadelphia perceived their psychological symptoms after injury and the factors that guided their decisions to seek professional mental health help. The study found that despite suffering from severe psychological symptoms, very few ...

Lung stem cells repair airways after injury

Researchers at the University of Iowa have discovered glandular myoepithelial cells that can regenerate airways after severe injury. These reserve stem cells can develop into new replacement cells in both submucosal glands and the lining of the airway, offering a potential therapeutic target for lung diseases.
