Scientists have announced a major discovery that has profound importance for our understanding of brain fog and cognitive decline seen in some patients with Long COVID. The findings showed that there was disruption to the integrity of the blood vessels in the brains of patients suffering from Long COVID and brain fog. This blood vessel 'leakiness' was able to objectively distinguish those patients with brain fog and cognitive decline compared to patients suffering from Long-COVID but not with brain fog.
Researchers have unraveled how mutations in a gene can lead to an incurable neurodevelopmental disorder that causes abnormal brain development in newborns and infants.
A large-scale clinical trial of treatment strategies for Crohn's disease has shown that offering early advanced therapy to all patients straight after diagnosis can drastically improve outcomes, including by reducing the number of people requiring urgent abdominal surgery for treatment of their disease by ten-fold.
Quick-acting targeted therapies with minimal side effects are an urgent need for the treatment of anxiety-related disorders. While delta opioid receptor (DOP) agonists have shown 'anxiolytic' or anxiety-reducing effects, their mechanism of action is not well-understood. A new study highlights the role of specific neuronal circuits in the brain involved in the development of anxiety, and distinct mechanisms of action of the therapeutic DOP agonist -- KNT-127.
If storms become stronger in the future due to climate change, more nitrogen may be released from the bottom of coastal seas.
Researchers have demonstrated that it is possible to provide accurate, high-resolution predictions of carbon cycles in agroecosystems, which could help mitigate the impacts of climate change.
Astronomers have characterized a bright quasar, finding it to be not only the brightest of its kind, but also the most luminous object ever observed. Quasars are the bright cores of distant galaxies and they are powered by supermassive black holes. The black hole in this record-breaking quasar is growing in mass by the equivalent of one Sun per day, making it the fastest-growing black hole to date.
A large-scale review provides an update on the recent advances in understanding and managing risk factors for atrial fibrillation (AF).
A research team has unveiled a groundbreaking technology that can recognize human emotions in real time.
Whether ultramarine, cerulean, Egyptian or cobalt, blue pigments have colored artworks for centuries. Now, seemingly out of the blue, scientists have discovered a new blue pigment that uses less cobalt but still maintains a brilliant shine. Though something like this might only happen once in a blue moon, the cobalt-doped barium aluminosilicate colorant withstands the high temperatures found in a kiln and provides a bright color to glazed tiles.
Scientists suspect Mars once had long-lived rivers, lakes and streams. Today, water on Mars is found in ice at the poles and trapped below the Martian surface. Researchers now reveal that Mars also may have had hydrothermal systems based on the hydrated magnesium sulfate the rover identified in the volcanic rocks.
Researchers have paired a deep learning model with experimental data to 'decode' mouse neural activity. Using the method, they can accurately determine where a mouse is located within an open environment and which direction it is facing, just by looking at its neural firing patterns. Being able to decode neural activity could provide insight into the function and behavior of individual neurons or even entire brain regions.
Research shows this tool can strongly support clinicians for patient care.
A new study demonstrated the use of deep brain stimulation (DBS) to map a 'human dysfunctome' -- a collection of dysfunctional brain circuits associated with different disorders.
Graphene is an enormously promising material. It consists of a single layer of carbon atoms arranged in a honeycomb pattern and has extraordinary properties: exceptional mechanical strength, flexibility, transparency and outstanding thermal and electrical conductivity. If the already two-dimensional material is spatially restricted even more, for example into a narrow ribbon, controllable quantum effects can be created. This could enable a wide range of applications, from vehicle construction and energy storage to quantum computing.
First large-scale analysis of optimal timing for flu shots finds October is the best month for children to get vaccinated against influenza. Study of 800,000 pediatrician visits leverages links between children's birth month, annual physical schedule, and vaccination timing.
According to IISc., the team adopted an approach used earlier to screen antibodies against HIV and COVID-19 in order to synthesise the new venom-neutralising antibody
This week’s science quiz is on the study of things.
Evidence is preserved in ancient volcanic and sedimentary rocks dating back to the Archaean age, between 4 billion and 2.5 billion years ago.
