How can our brain still perceive familiar objects even when they become indistinct?

Researchers have explored the brain neuronal mechanism that allows the perception of familiar images even if they are indistinct. They found that the number of neurons responding to low-contrast rather than high-contrast visual stimuli increased in rats performing a visual orientation discrimination task after repeated experiences. These neurons showed stronger activities in correct-choice than incorrect-choice trials. These neurons efficiently represented low-contrast stimulations. Thus, the low-contrast preference in V1 activity may contribute to improved low-contrast visual. discrimination. from Top Health News -- ScienceDaily https://ift.tt/2ZFO4MU via IFTTT

Delta-like SARS-CoV-2 variants are most likely to increase pandemic severity

Mathematical model indicates SARS-CoV-2 variants that combine enhanced transmissibility with the ability to escape immunity cause more infections than variants with either trait alone. Understanding which type of variants are most likely to increase infections and pandemic severity could help researchers and public health officials interpret the significance of novel and existing variants and design tailored public health responses for various scenarios based on a variant's characteristics. In the case of Delta-like variants, vaccination is predicted to be highly beneficial because vaccinations would prevent a greater number of cases that a more transmissible virus would potentially cause, and because the milder nature of breakthrough infections should substantially reduce overall mortality. from Top Health News -- ScienceDaily https://ift.tt/3p2c3i1 via IFTTT

Taking it easy as you get older? Wrong

A team of evolutionary biologists and biomedical researchers lay out evolutionary and biomedical evidence showing that humans, who evolved to live many decades after they stopped reproducing, also evolved to be relatively active in their later years. The researchers say that physical activity later in life shifts energy away from processes that can compromise health and toward mechanisms in the body that extend it. They hypothesize that humans evolved to remain physically active as they age -- and in doing so to allocate energy to physiological processes that slow the body's gradual deterioration over the years. This guards against chronic illnesses such as cardiovascular disease, type 2 diabetes, and even some cancers. from Top Health News -- ScienceDaily https://ift.tt/3cG5Dz1 via IFTTT

The brain uses bodily signals to regulate fear

Fear is essential for survival, but must be well regulated to avoid harmful behaviors such as panic attacks or exaggerated risk taking. Scientists have now demonstrated in mice that the brain relies on the body's feedback to regulate fear. The brain's insular cortex strongly reacts to stimuli signaling danger. However, when the body freezes in response to fear, the heartbeat slows down leading to attenuated insular cortex activity. Processing these opposing signals helps the insular cortex to keep fear in balance. The body's reactions are thus actively used to regulate emotions and are much more than passive emotional responses. from Top Health News -- ScienceDaily https://ift.tt/3kOiX9d via IFTTT

Malaria parasite genomes provide insights and tools for control and elimination in Lake Victoria, Kenya

Scientists are turning to genomics to better understand the epidemiology of malaria and to inform control and elimination interventions and strategies. In the Lake Victoria region of Kenya, malaria burden remains very high despite more than a decade of intense control activities. A team of researchers generated whole Plasmodium falciparum genome sequences from the lake region. Their analyses revealed that malaria parasites from this region appear distinct from other parasites from East Africa, while frequencies of known drug resistance markers were similar to those in other East African parasite populations. from Top Health News -- ScienceDaily https://ift.tt/3ciwSQ5 via IFTTT

Air pollution decrease in India during COVID-19 lockdown not as high as originally thought

Observational data shows air pollution in India decreased drastically in the first COVID-19 lockdown when emissions from vehicles naturally declined, but researchers say those numbers only tell part of the story -- blue skies and an absence of visible smog can be deceiving and hide pollutants that could potentially cause health issues. from Top Health News -- ScienceDaily https://ift.tt/3Ckhj51 via IFTTT

As we develop, the brain connects lessons learned differently

A new study of brain activity patterns in people doing a memory task finds that the way we make inferences -- finding hidden connections between different experiences -- changes dramatically as we age. The study's findings might one day lead to personalized learning strategies based on a person's cognitive and brain development. The researchers found that whereas adults build integrated memories with inferences already baked in, children and adolescents create separate memories that they later compare to make inferences on the fly. from Top Health News -- ScienceDaily https://ift.tt/30odFtB via IFTTT

Nascent polypeptides stabilize ribosomes for uninterrupted translation

Protein production (translation) is a complex process involving machinery called ribosomes. How do cells counter ribosomal destabilization leading to premature termination of translation? Scientists have uncovered a novel role of nascent protein chains in stabilizing translating ribosomes. They suggest that longer peptide sequences spanning the ribosomal exit tunnel and bulky amino acid residues in the tunnel entry help stabilize the ribosome by bridging its subunits, ensuring uninterrupted translation. from Top Health News -- ScienceDaily https://ift.tt/31V38Xy via IFTTT

Obesity raises the risk of gum disease by inflating growth of bone-destroying cells

Chronic inflammation caused by obesity may trigger the development of cells that break down bone tissue, including the bone that holds teeth in place, according to new research that sought to improve understanding of the connection between obesity and gum disease. The study, completed in an animal model and published in October in the Journal of Dental Research, found that excessive inflammation resulting from obesity raises the number of myeloid-derived suppressor cells (MDSC), a group of immune cells that increase during illness to regulate immune function. MDSCs, which originate in the bone marrow, develop into a range of different cell types, including osteoclasts (a cell that breaks down bone tissue). from Top Health News -- ScienceDaily https://ift.tt/30kFH9U via IFTTT

This is how we understand emoji

Even when emoji are used to substitute for words, we still understand the sentence. But how does that work? Do we interpret an emoji primarily as an image or as a word? To find out, a research team asked volunteers to read texts with emoji and measured the reading time precisely. It turns out that it takes a little longer to comprehend a sentence that includes emoji than one that doesn't. If the emoji does not directly represent the intended meaning, but another word with the same pronunciation, we need yet a little more time. Based on these results, the team concludes that emoji comprehension consists of two steps: first the image is interpreted, then the word is inferred. from Top Health News -- ScienceDaily https://ift.tt/3kuik4e via IFTTT
