Contrary to previous assumptions, nerve cells in the human neocortex are wired differently than in mice. Those are the findings of a new study conducted by Charité – Universitätsmedizin Berlin and published in the journal Science.* The study found that human neurons communicate in one direction, while in mice, signals tend to flow in loops. This increases the efficiency and capacity of the human brain to process information. These discoveries could further the development of artificial neural networks. The neocortex, a critical structure for human intelligence, is less than five millimeters thick. There, in the outermost layer of the brain, 20 billion neurons process ...

Scientists Identify Airway Cells That Sense Aspirated Water and Acid Reflux  The new work by UCSF researchers could lead to interventions to prevent pneumonia or treat certain types of chronic cough.  When a mouthful of water goes down the wrong pipe – heading toward a healthy person’s lungs instead of their gut – they start coughing uncontrollably. That’s because their upper airway senses the water and quickly signals the brain. The same coughing reflex is set off in people with acid reflux, when acid from the stomach reaches the throat.  Now, UC San Francisco scientists have identified the rare type of cell responsible ...

The land under nearly half of China’s major cities is undergoing moderate to severe subsidence, affecting roughly one-third of the nation’s urban population, according to a systematic national-scale satellite assessment. The findings suggest that within the next century, 22 to 26% of China’s coastal land will have a relative elevation lower than sea level, putting hundreds of millions of people at elevated risk of flooding due to sea-level rise. Over the last several decades, China has experienced one of the most rapid and extensive urban expansions in human history. This massive wave of urbanization may be threatened ...

Drugs of abuse, like cocaine and opioids, alter neuronal signaling in the nucleus accumbens (NAc), hijacking a key brain reward system involved with the fulfillment of innate needs for survival, according to a new study in mice. The findings provide mechanistic insights into the intensification of drug-seeking behaviors in substance use disorders. Persistent drug use is accompanied by a profound reprioritization of motivations, skewing decision-making behaviors toward a myopic focus on drug use over other innate needs, like eating or drinking water, often ...

The energy density of supercapacitors – battery-like devices that can charge in seconds or a few minutes – can be improved by increasing the ‘messiness’ of their internal structure. Researchers led by the University of Cambridge used experimental and computer modelling techniques to study the porous carbon electrodes used in supercapacitors. They found that electrodes with a more disordered chemical structure stored far more energy than electrodes with a highly ordered structure. Supercapacitors are a key technology for the energy transition and could be useful for certain forms of public transport, as well as for ...

An international research team led by scientists from the CNRS1 has discovered that the magnetic nanobubbles2 known as skyrmions can be moved by electrical currents, attaining record speeds up to 900 m/s. Anticipated as future bits in computer memory, these nanobubbles offer enhanced avenues for information processing in electronic devices. Their tiny size3 provides great computing and information storage capacity, as well as low energy consumption. Until now, these nanobubbles moved no faster than 100 m/s, which is too slow for computing applications. ...

(MEMPHIS, Tenn. – April 18, 2024) Metabolic health (normal blood pressure, blood sugar and cholesterol levels, among other factors) influences the effectiveness of influenza vaccinations. Vaccination is known to be less effective in people with obesity compared to those with a healthier body mass index (BMI), but St. Jude Children’s Research Hospital scientists have found it is not obesity itself, but instead metabolic dysfunction, which makes the difference. In a study published today in Nature Microbiology, the researchers found switching obese mice to a healthy diet before flu vaccination, but not after, completely protected ...

Health-care professionals who work with people experiencing homelessness know many of the people may also be living with a mental health disorder. University of Calgary researchers wanted to better understand how often these two things are connected, and what they found surprised them. “We found 66-to-75 per cent of people who are experiencing homelessness have an underlying mental health condition” says Dr. Dallas Seitz, MD, PhD, a psychiatrist and clinician-researcher at the Cumming School of Medicine, and senior author of the paper. “We have always ...

The 2010 Gulf of Mexico Deepwater Horizon was the largest accidental oil spill in history. With almost 100 million gallons (379 million liters) of oil combined with dispersants suggested to remain in the Gulf, it is one of the worst pollution events ever. More than a decade later, its long-term effects  are still not fully understood. In a new study, researchers from Louisiana State University and Tulane University examined the endemic Gulf of Mexico fish species that may have been most impacted by the oil spill to see how their distribution has changed over the years. To get their data, they studied museum specimens from natural ...

CAMBRIDGE, MA — Have you ever felt reluctant to share ideas during a meeting because you feared judgment from senior colleagues? You’re not alone. Research has shown this pervasive issue can lead to a lack of diversity in public discourse, especially when junior members of a community don’t speak up because they feel intimidated. Anonymous communication can alleviate that fear and empower individuals to speak their minds, but anonymity also eliminates important social context and can quickly skew too far in the other direction, leading to toxic or hateful speech. MIT ...

Animal and plant populations have been extensively studied, which has helped to understand ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations due to the impossibility of isolating, culturing and analyzing the genetic content of the different species and their individuals in the laboratory. Therefore, although it is known that populations of microorganisms include a great diversity, this remains largely uncharacterized. Now, a new study from the Institut de Ciències del Mar (ICM-CSIC) recently published in the journal Microbiome highlights the potential of marine microbial populations as indicators ...

Twin studies have proven invaluable for teasing out the effects of both genetics and the environment on human biology. In a study published April 2 in Cell Reports, researchers studied pairs of twins to look at how the interplay of genetics and environment affect cognitive processing—the way that people think. They found that some cognitive abilities appear to be regulated more by environmental factors than by genetics. “Past research has suggested that general intelligence—often referred to as intelligence quotient or IQ—has a heritability ranging from 50% to 80%,” says senior and corresponding author Xiaohong Wan of Beijing Normal University in China. ...
