Researchers map gene switches and brain cell types associated with schizophrenia, bipolar disorder, Alzheimer’s.
Alzheimer’s disease is a disease that attacks the brain, causing a decline in mental ability that worsens over time. It is the most common form of dementia and accounts for 60 to 80 percent of dementia cases. There is no current cure for Alzheimer’s disease, but there are medications that can help ease the symptoms.
During the mid-20th century, scientists discovered that protons have the ability to resonate, akin to the vibrations of a bell. Over the subsequent thirty years, advancements have led to 3D pictures of the proton and significant insight into its structure in its ground state. However, there remains limited knowledge about the 3D structure of a resonating proton.
A recent experiment conducted at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility has delved deeper into the three-dimensional structures of both proton and neutron resonances. This research provides one more puzzle piece to the vast picture of the chaotic, nascent universe that existed just after the Big Bang.
The Big Bang is the leading cosmological model explaining how the universe as we know it began approximately 13.8 billion years ago.
According to a study recently presented at the European Respiratory Society International Congress in Milan, Italy, young people who have used e-cigarettes are more than twice as likely to report experiencing chronic stress.
The study was presented by Dr Teresa To, a senior scientist at The Hospital for Sick Children (SickKids) in Toronto, Canada. She said: “Research is starting to show how vaping affects young people’s physical and mental health. For example, our previous research has shown that those who vape are more likely to suffer an asthma attack. In this study, we were particularly interested in the relationship between vaping, mental health, and quality of life among young people.”
Mercury’s exploration by the Mio spacecraft revealed localized chorus waves in its magnetosphere. International research utilized advanced theories and simulations to understand these waves, emphasizing the magnetosphere’s vital role in shielding planets from cosmic radiation.
Since Mercury is the closest planet to the Sun among the solar system planets, it is strongly influenced by the solar wind, a high-speed (several hundred km/s) stream of plasma.
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of positive ions and free electrons. It was first described by chemist Irving Langmuir in the 1920s.
Regenerative medicine researcher Kristy Red Horse’s discoveries may someday help damaged hearts heal better. Her stewardship of her Native American heritage may advance science in other ways too.
Exciton polaritons, hybrid quasiparticles caused by the strong exciton-photon coupling, constitute a unique prototype for studying many-body physics and quantum photonic phenomena traditionally in cryogenic conditions.
Atomically thin transition-metal dichalcogenides (TMDs), as exceptional semiconductors with room-temperature operations, have received much attention due to their fascinating valleytronics features and strong exciton resonance. Nevertheless, in TMDs microcavities, the overall nonlinear interaction strength of polaritons can be insignificant compared to that of other wide-bandgap semiconductors.
Considerable effort has been devoted to improving the nonlinear interactions, for instance, by resorting to 2s states, trion, and moiré or dipolar excitons. However, these excitons quickly dissipate at elevated temperatures and then destroy the strong coupling condition. Thus, achieving an appropriate combination of strong nonlinearity together with the thermal stability of the TMDs polaritons is highly sought after for realistic polariton-based integrated devices.
Computer vision algorithms have become increasingly advanced over the past decades, enabling the development of sophisticated technologies to monitor specific environments, detect objects of interest in video footage and uncover suspicious activities in CCTV recordings. Some of these algorithms are specifically designed to detect and isolate moving objects or people of interest in a video, a task known as moving target segmentation.
While some conventional algorithms for moving target segmentation attained promising results, most of them perform poorly in real-time (i.e., when analyzing videos that are not pre-recorded but are being captured in the present moment). Some research teams have thus been trying to tackle this problem using alternative types of algorithms, such as so-called quantum algorithms.
Researchers at Nanjing University of Information Science and Technology and Southeast University in China recently developed a new quantum algorithm for the segmentation of moving targets in grayscale videos. This algorithm, published in Advanced Quantum Technologies, was found to outperform classical approaches in tasks that involve the analysis of video footage in real-time.
Dementia affects more than 55 million people around the world.
A number of factors can increase a person’s risk of developing dementia, including high blood pressure, poor sleep, and physical inactivity.
Meanwhile, keeping cognitively, physically, and socially active, and limiting alcohol consumption, can reduce the risk.
Recently, a large Swedish study observed that chronic stress and depression were linked to a higher risk of developing Alzheimer’s disease, the most common form of dementia. The researchers found people with a history of both chronic stress and depression had an even greater risk of the disease.
Globally, around 280 million people have depression, while roughly 300 million… More.
