Over-fed bacteria make people sick

A Kiel University team proposes that over-fed bacteria disrupt the human microbiome, leading to disease development. The researchers suggest that an unnatural nutrient supply decouples bacteria from their host organisms, promoting disease growth.

Mindfulness smoking-cessation app can change the brain

A mindfulness-based smartphone app was found to reduce self-reported daily cigarette consumption and decrease brain reactivity to smoking images in study participants. Those who showed the greatest reduction in cigarette consumption also exhibited decreased brain activity in a region associated with craving.

3D images reveal how infants' heads change shape during birth

Researchers captured detailed images of infants' skulls and brains before and during delivery using 3D MRI, finding that fetal head molding occurs in all seven infants, with different parts of the skull overlapping. The study suggests that infants experience greater skull stresses during birth than previously thought, potentially under...

Cellular rivalry promotes healthy skin development

In a recent study, Rockefeller scientists found that skin cells in mice engage in two forms of competition, one during early embryonic development and the other before birth. Loser cells are eliminated by winners, promoting healthy tissue development. Disrupting this process leads to slower skin development and reduced barrier function.

On the way to fighting staph infections with the body's immune system

Researchers have discovered that gamma/delta T cells are the specific cells mediating the mouse's defense against Staphylococcus aureus (MRSA) infection. In a study published in the Proceedings of the National Academy of Sciences, researchers identified V gamma 6/Vdelta 4+ gamma/delta T cells as the key players in this response.

Blood flow command center discovered in the brain

A team of researchers from Australia, France, New Zealand, and the UK have discovered a group of brain cells that function as a 'master-controller' for the cardiovascular system. These cells, found in the medulla oblongata, coordinate activity across the cardiovascular system, including blood flow to the heart and blood vessels.

New AI sees like a human, filling in the blanks

Researchers at the University of Texas at Austin developed an AI agent that can gather visual information and reconstruct a full 360-degree image of its surroundings. The agent uses deep learning to choose the most informative shots, similar to how humans would take pictures in different directions based on prior experience.

Optimizing device implantation in patients with atrial fibrillation and risk of stroke

Researchers developed a web-based platform to optimize left atrial appendage occluder device therapies for patients with atrial fibrillation and stroke risk. The VIDAA platform combines biophysical models, interactive interfaces, and computational simulations to identify optimal device configurations and positioning strategies.
