Researchers at Eötvös Loránd University have investigated whether the perception of time changes with age, and if so, how, and why we perceive the passage of time differently. Their study was published in Scientific Reports.
Can the brain, with its limited realization of precise mathematical operations, compete with advanced artificial intelligence systems implemented on fast and parallel computers? From our daily experience we know that for many tasks the answer is yes! Why is this and, given this affirmative answer, can one build a new type of efficient artificial intelligence inspired by the brain? In an article published today in Scientific Reports, researchers from Bar-Ilan University in Israel solve this puzzle.
Nucleic acid-targeting photodynamic therapy (PDT) is a promising type of targeted therapy that is being actively researched. This treatment relies on special photosensitizers, a type of drug that binds at specific locations in a cell’s DNA.
Experiencing childhood trauma may lead an individual to volunteer, donate money or contact their elected officials about environmental issues later in life, according to recent research published in Scientific Reports.
Researchers at the Eötvös Loránd University (ELTE) Department of Ethology, Budapest investigated if companion pigs and dogs would show their owners the location of a food reward out-of-their reach (but reachable for their owner).
Adults with high levels of attention-deficit hyperactivity disorder (ADHD) symptoms are more likely to experience anxiety and depression than adults with high levels of autistic traits, according to new research led by psychologists at the University of Bath in the UK.
A specific colonization of microbes in the reproductive tract is commonly found in women with ovarian cancer, according to a new study from Mayo Clinic's Center for Individualized Medicine. The discovery, published in Scientific Reports, strengthens evidence that the bacterial component of the microbiome — a community of microorganisms that also consists of viruses, yeasts and fungi — is an important indicator for early detection, diagnosis and prognosis of ovarian cancer.
People don’t always behave impeccably in relationship to others. When we notice that this has inadvertently caused harm, we often feel guilty. This is an uncomfortable feeling and motivates us to take remedial action, such as apologizing or owning up.
A new study analyzed the value of establishing ecological corridors for large mammals between Yellowstone and Glacier National Parks and between Mount Rainier and North Cascades National Parks. These corridors would enlarge populations and species to shift their geographic ranges more readily in response to climate change.
RUDN University researchers have found a distinctive property of cells in the blood of patients with preeclampsia, a dangerous complication that occurs during pregnancy. The causes of this pathology are still unknown to scientists, but the results obtained may be evidence of one of the hypotheses of the origin of preeclampsia.
Columbia Engineering researchers report that they have developed a new experimental pipeline to combine bacterial therapy with current cancer drugs. Their study, which explores resistance to bacterial therapy at the molecular level, has achieved better treatment efficacy without additional toxicity in laboratory models.
Mining gold high in the mountains is a risky job. Not everyone can endure such workload, so a medical examination is essential for hiring. The RUDN medic with a colleague from Kyrgyzstan found out that the standard contraindications list needs an update. The usual physiological parameters practically do not affect the probability of whether a person will survive at the workplace, but smoking and some other factors can affect this.
RUDN University doctors conducted the first large-scale study of occupational diseases of workers in the electrolysis production of nickel. The most common diseases were bronchitis and asthma, and the most vulnerable group were cleaners of finished products.
Astronauts could be given an enhanced diet during spaceflights that includes a greater variety and quantity of fruits, vegetables, and fish to improve their health and performance compared to standard spaceflight food, reports a study published in Scientific Reports.
There is a critical need for non-invasive solutions to monitor heart failure progression around the clock. This novel wearable device is based on sensors embedded in a lightweight belt that monitors thoracic impedance, electrocardiogram (ECG), heart rate and motion activity detection. The device was tested in different conditions including sitting, standing, lying down and walking. Findings showed that all of sensors kept track of the changes for all of the different conditions.
Diplodocids – large herbivorous dinosaurs with long necks and tails – may have been able to move their tails like bullwhips at speeds of up to 33 metres per second (more than 100 kilometres per hour), according to a modelling study published in Scientific Reports.
Using a new analytical method, Empa researchers have tracked viruses as they pass through face masks and compared their failure on the filter layers of different types of masks. The new method should now accelerate the development of surfaces that can kill viruses, the team writes in the journal Scientific Reports.
The precise relationship between vaccine hesitancy and COVID-19 vaccination side effects has not previously been explored in vaccinated persons. A fundamental question arises in regard to the directionality of this vaccine hesitancy-vaccine side effect link, namely which variable predicts which. One possibility is that side effects from an earlier dose predict one’s vaccine hesitancy towards a later dose. Alternatively, one’s psychological negativity (hesitancy) towards an earlier dose could predict subsequent side effects from a later vaccination dose. The latter direction reflects a Nocebo effect, i.e., side effects driven by psychological factors rather than by an active treatment component. Results showed only the latter direction to be true. Namely, only earlier vaccine hesitancy towards the second COVID-19 dose predicted subsequent nocebo side-effects following the booster vaccination. To put this in perspective up to 16% of one’s vaccine side effects were explained by earlier va
While most animals don’t learn their vocalizations, everyone knows that parrots do – they are excellent mimics of human speech. Researchers aim to add to what we know about animal vocal learning by providing the largest comparative analysis to date of parrot vocal repertoires.
A Martian megatsunami may have been caused by an asteroid collision similar to the Chicxulub impact – which contributed to the mass extinction of all non-avian dinosaurs on Earth 66 million years ago – in a shallow ocean region, according to a study published in Scientific Reports.
Collaborative research between SMU nanorobotics authority MinJun Kim’s Biological Actuation, Sensing, and Transport (BAST) Lab and international research and engineering company ARA has demonstrated for the first time that certain chemical coatings, applied to micro/nanoparticles, can alter their swimming propulsion within biological fluids.
Volcanic eruptions are dangerous and difficult to predict. A team at the University of Tokyo has found that the ratio of atoms in specific gases released from volcanic fumaroles (gaps in the Earth’s surface) can provide an indicator of what is happening to the magma deep below — similar to taking a blood test to check your health.
Engineers and physicians at UC San Diego have developed a device to non-invasively measure cervical nerve activity in humans, a new tool they say could potentially inform and improve treatments for patients with sepsis or post-traumatic stress disorder.
