| Wear and tear in vulnerable brain areas lead to lesions linked to cognitive decline Posted: 17 Dec 2021 02:27 PM PST As our brains age, small lesions begin to pop up in the bundles of white matter that carry messages between our neurons. The lesions can damage this white matter and lead to cognitive deficits. Now, researchers not only provide an explanation for the location of these lesions but also how they develop in the first place. |
| Using ergonomics to reduce pain from technology use Posted: 17 Dec 2021 09:38 AM PST The use of smartphones, tablets and laptops has become commonplace throughout the world and has been especially prevalent among college students. Recent studies have found that college students have higher levels of screen time, and they utilize multiple devices at higher rates compared to previous generations. |
| How the brain understands one voice in a noisy crowd Posted: 17 Dec 2021 08:32 AM PST Researchers find that the brain is taking an extra step when listening to one speaker in a crowd, and not taking that step with the other words swirling around the conversation. |
| In last 15 years, deforestation made outdoor work unsafe for millions Posted: 17 Dec 2021 08:32 AM PST The tropics is becoming hotter due to a combination of warming associated with deforestation and climate change -- and that can reduce the ability of outdoor workers to perform their jobs safely. Researchers estimated how many safe working hours people living in the tropics have lost due to local temperature change associated with loss of trees during the past 15 years. |
| Understanding cobalt’s human cost Posted: 17 Dec 2021 08:32 AM PST After studying the impacts of mining cobalt -- a common ingredient in lithium-ion batteries -- on communities in Africa's Democratic Republic of the Congo (DRC), an interdisciplinary team of researchers is calling for more data into how emerging technologies affect human health and livelihoods. |
| Pain and anxiety impact breathing on a cellular level Posted: 17 Dec 2021 08:29 AM PST A team of scientists has uncovered a neural network in the brain that coordinates breathing rhythm with feelings of pain and fear. Along with contributions to the fields of pain management, psychological theories of anxiety, and philosophical investigations into the nature of pain, their findings could lead to development of an analgesic that would prevent opioid-induced respiratory depression (OIRD), the disrupted breathing that causes overdose deaths. |
| Keeping active through varied activities can reduce risk of developing dementia Posted: 17 Dec 2021 07:28 AM PST Older adults who participate in a variety of different activities are able to reduce their risk of developing dementia, according to a new study. |
| New device advances commercial viability of solar fuels Posted: 17 Dec 2021 07:28 AM PST A research team has developed a new artificial photosynthesis device with remarkable stability and longevity as it converts sunlight and carbon dioxide into two promising sources of renewable fuels -- ethylene and hydrogen. |
| Research takes early step towards drug to treat common diabetes complication hypoglycemia Posted: 17 Dec 2021 07:28 AM PST New research has taken an important step towards the goal for a treatment for the common diabetes complication hypoglycemia, or low blood sugar. Researchers found a way help to defend against hypoglycemia by boosting hormonal defense systems. The team believes they have identified a promising target in the brain could be useful for future drug development to create an anti-hypoglycemia drug. |
| Rollercoaster of emotions: Exploring emotions with virtual reality Posted: 17 Dec 2021 07:28 AM PST To the left and right, the landscape drifts idly by, the track in front of you. Suddenly, a fire. The tension builds. The ride reaches its highest point. Only one thing lies ahead: the abyss. Plummeting down into the depths of the earth. These are scenes of a rollercoaster ride as experienced by participants in a recent study. However, not in real life, but virtually, with the help of virtual reality (VR) glasses. The aim of the research was to find out what happens in participants' brains while they experience emotionally engaging situations. |
| Research breakthrough could see HIV drugs used to treat low-grade brain tumors Posted: 17 Dec 2021 07:27 AM PST Drugs developed to treat AIDS and HIV could offer hope to patients diagnosed with the most common form of primary brain tumor. The breakthrough is significant because, if further research is conclusive, the anti-retroviral drugs could be prescribed for patients diagnosed with meningioma and acoustic neuroma brain tumors (also known as schwannoma). |
| New research sheds light on how ultrasound could be used to treat psychiatric disorders Posted: 17 Dec 2021 07:27 AM PST A new study has shown how the brain gives credit to events, along with how transcranial ultrasound (TUS) can disrupt this process. While currently developed in an animal model, this line of research and the use of TUS could one day be applied to clinical research to tackle conditions such as addiction. |
| One algorithm to rule decision-making Posted: 17 Dec 2021 07:27 AM PST Researchers uncover a single rule for how animals make spatial decisions while on the move. |
| Limited brain capacity in humans and birds Posted: 17 Dec 2021 07:27 AM PST Birds and humans have very different networks of neurons in their brains. Nevertheless, their working memory is limited by similar mechanisms. |
| Pioneering new technique to barcode cells Posted: 17 Dec 2021 07:27 AM PST Scientists have developed a pioneering new technique to barcode individual cells more accurately and efficiently - which could help pave the way for quicker disease diagnosis. |
| Addiction relapse driven by drug-seeking habit, not just drug Posted: 17 Dec 2021 07:27 AM PST Why are some individuals able to use recreational drugs in a controlled way, whereas others switch to the compulsive, relapsing drug-seeking and -taking habits that characterize substance use disorder (SUD)? Despite more than six decades of extensive research, the question remains unanswered, hampering the development of targeted prevention and therapeutic strategies. Now, a new study in rats has identified the maladaptive nature of drug-seeking habits and how they contribute to the perpetuation of addiction by promoting the tendency to relapse. |
| New hiding place for antibiotic resistance Posted: 16 Dec 2021 12:02 PM PST Genes that make bacteria resistant to antibiotics can persist longer than it was previously believed. This was recently shown in a new study that reports a previously unknown hiding place for these genes. The finding represents a new and important piece in the puzzle to understand how bacterial antibiotic resistance works. |
| Specific components of air pollution identified as more harmful than others Posted: 16 Dec 2021 12:01 PM PST Ammonium is one of the specific components of fine particulate matter (PM2.5), that has been linked to a higher risk of death compared to other chemicals found in it, according to a new study. |
| Stem cells organize themselves into embryoid Posted: 16 Dec 2021 12:01 PM PST Researchers have developed a method to generate embryo-like cell complexes from the stem cells of mice. The method provides new insights into embryonic development. In the medium term, it might also be suitable for developing tests for substances that could be harmful to fertility. |
| Women who practice self-compassion are at lower risk of cardiovascular disease Posted: 16 Dec 2021 12:00 PM PST Middle-aged women who practiced self-compassion had lower risk of developing cardiovascular disease, irrespective of their blood pressure, insulin resistance and cholesterol levels. |
