Starting from the top, a strong heart leads the way. The sinoatrial node, an oval-shaped piece of tissue in the upper right chamber, is the heart's natural pacemaker. The organ maintains its regular rhythm thanks to the periodic electrical impulses it emits. [more…]
How memories deteriorate with aging has been demonstrated through a model for storing information in the brain. Attractive networks are theoretical constructs that provide a model for how the brain stores memories. New to these networks [more…]
The receptor for the hormone oxytocin, which is thought to be crucial in establishing social bonds, doesn't play the important role scientists have attributed to it for the past 30 years, according to new research from UC San Francisco and Stanford Medicine researchers. [more…]
Aydoğan Özcan received the 2023 SPIE Dennis Gabor Diffractive Optics Award. Outstanding achievements in diffractive wavefront technology, particularly those driving the development of holography and metrology applications, were awarded the SPIE Dennis Gabor Diffractive Optics Award. [more…]
In the Randomized REMAP-CAP Study (JAMA. 2023;329(1):39-51) published in the JAMA medical journal, IL-6 receptor antagonists (tocilizumab, sarilumab, satralizumab, and siltuximab) and anti-platelet agents in patients with COVID-19 were in poor general condition. survive long term (six month) [more…]
A University of East Anglia study shows that women at risk for Alzheimer's disease may benefit from hormone replacement therapy (HRT). Study has APOE4 gene, highest risk factor gene for Alzheimer's disease [more…]
Robotic dental implant surgery is beginning to be said to result in less discomfort and faster patient recovery times. Neocis, a technology startup, is a dental implant to assist dentists during implant surgery. [more…]
According to a randomized controlled trial published in Frontiers in Nutrition, male and female participants who consumed 57 g of almonds daily for a month had blood levels of the healthy fat 12,13-dihydroxy-9Z-octadecenoic acid (12,13-DiHOME), [more…]
The human brain's power to manage many bodily systems, from controlling your heart rate to controlling your emotions, makes it an incredible piece of hardware. If we still do not fully understand the intricacies of the brain, [more…]
Scientists are investigating whether macrophages, important participants in post-traumatic recovery, can detect and respond to the damage caused by a heart attack. A patient's blood changes after a heart attack, resulting in dead cells, [more…]
Activation of MAP2K signaling through genetic engineering or non-invasive repetitive transcranial magnetic stimulation (rTMS) can help people with spinal cord injury (SCI) [more…]
A study that could help understand how malignant diseases spread reveals that a model developed to explain wetting droplets can also describe cell migration caused by differences in the hardness of a surface. embryos [more…]
Until a few hours ago, the solid reddish structure of a healthy organ was a figure floating in a large jar. White tubes resembling tree branches are now partially visible. This is a substitute for scientists [more…]
Parkinson's disease is a neurological condition that progressively impairs movement and can lead to tremors, stiffness, balance and coordination problems. Cells that produce dopamine, a neurotransmitter essential for the body's movement and reward systems [more…]
The introduction of minimally invasive robotic surgery has changed the game for patients around the world. Many traditional procedures today can be inserted into the patient's body through small incisions no larger than a quarter inch. [more…]
The layer that separates the inside of living cells from their surroundings, protects them and enables the cell to perform its basic functions is known as the cell membrane or plasma membrane. Some membrane proteins stimulate cells to extracellular stimuli. [more…]
Researchers are examining whether vitamins can help prevent cancer and heart disease in a cohort of close to 700.000 people. More than half of adults in the US are already taking vitamins, and their use is on the rise. 2021 in USA only [more…]
According to an international team of researchers, including Sofia Kulikova, Senior Research Fellow at HSE University-Perm, ketamine, an NMDA receptor inhibitor, increases the background noise in the brain, resulting in increased sensory input. [more…]
Roundworm C. elegans can live longer thanks to genetically modified mitochondria, according to a new study published in the journal Nature Aging. This work borrows a strategy from the renewable energy field. sun in humans [more…]
Babies' spontaneous, random movements help build their sensory-motor systems, according to the latest research by the University of Tokyo. To assess muscle communication and sensation throughout the whole body, researchers used detailed movement of newborns and infants. [more…]
As expectations rise for a new experimental antibody thought to prevent cognitive decline in some Alzheimer's patients, a third drug-related death during clinical testing may raise concerns about the drug's safety. obtained by Science [more…]
MIT researchers have demonstrated that they can detect light deep within tissues such as the brain using a customized MRI sensor. It is particularly difficult to view light in deep tissues, as so much light is absorbed or scattered as it passes through tissue. [more…]
The deadliest cancer in both the United States and the rest of the world is lung cancer. Patients have little choice because most of the drugs currently available do not work. bacterial treatment, [more…]
Sometimes less is more when managing fluid flows. Nanopore-based devices that pass small amounts of liquid through microscopic channels have found use in molecular sensing, DNA sequencing, and even energy production. At the moment, [more…]
Small scars on the face do not significantly reduce a person's attractiveness, according to a new study. A new study in the latest issue of the journal Plastic & Reconstructive Surgery finds that small facial scars are attractive. [more…]
The digestive system consists of the digestive system and its accessory organs, which break down food into molecules that body cells can absorb and use. The food is gradually phased out until the waste products are eliminated and the molecules are small enough to be absorbed. [more…]
The Cellular and Molecular Bioengineering (CMBE) Special Interest Group of the Biomedical Engineering Society (BMES) accepted Georgia Tech professor Ahmet Coşkun as the Rising Star. Coşkun has honored this honor for over ten years. [more…]
New research from the Stowers Institute for Medical Research reveals key details about the survival and functioning of a dangerous selfish gene. The broader community investigating meiotic drive mechanisms is more than keen to understand this dynamic. [more…]
Thanks to the opening of a second beamline field at the Berkeley Lab Laser Accelerator (BELLA) Center, researchers will soon be able to study incredibly hot plasmas, research cancer treatments, and find new materials for quantum science. [more…]
Nerve cells need a lot of oxygen and energy. They get both through blood. This explains why there are so many blood arteries along the nerve tissue. well but vascular [more…]
