  • Research explores how brain learns, protects itself
    Gottingen [Germany]: It was studied during recent research that what happens when certain enzymes are blocked in mice and depending on whether the brain is healthy or diseased, the inhibition had opposite effects.The study by researchers at the University of Gottingen has been published in the Journal of Neuroscience. Learning and recovery from injuries depend on the plasticity of neuronal connections. Important for this are the macromolecules of the extracellular matrix, which are located between the nerve cells. When we grow up, the “stability” of this extracellular matrix increases, providing a scaffold for stabilising existing connections between the nerve cells and consolidating what we have learned.If we experience something new, the extracellular matrix must be loosened to allow new connections to form. This relationship between stability and plasticity in the brain is regulated in the matrix with the help of enzymes such as matrix metalloproteinases (MMPs), which can “digest” the extracellular matrix and thus “loosen” it. A team from the University of Gottingen has now been able to show in a new study that blocking the matrix metalloproteinases MMP2 and MMP9 can have opposing effects depending on whether the brain is sick or healthy.To measure neuronal plasticity, the scientists let adult mice see only through one eye for several days and recorded the resulting activity changes in the animals’ visual cortex. In a first experiment, they examined the adaptability of the visual cortex of […]
  • Extensive smartphones use by parents might damage toddler’s development
    Tel Aviv [Israel]: A new study has found that interaction between mothers and their toddlers is reduced by a factor of four when the mothers use their smartphones and this might damage their toddler’s development as well. The research has been published in the ‘Child Development Journal’.The new study was led by Dr Katy Borodkin of the Department of Communication Disorders at the Stanley Steyer School of Health Professions, Sackler Faculty of Medicine of Tel Aviv University. The experiment involved dozens of mothers of toddlers (aged two to three years). The mothers were ostensibly invited to participate in a study examining the link between the mother’s and the child’s interests, and so they were asked to perform three tasks: Browse a designated Facebook page and like videos and articles that interested them; read printed magazines and mark articles that interested them; and finally, play with the child while the smartphone and magazines were outside the room (uninterrupted free play). “Our goal was to simulate situations in real life where the mother has to take care of her child, while at the same time devoting some of her attention to her smartphone,” Dr Katy Borodkin explained. “The mothers were unaware of the purpose of the experiment, so they behaved naturally by splitting their interest between the toddlers and the smartphone and magazines. We videotaped all the interactions between the mothers and the toddlers and later […]

  • New Features: Instagram will be bringing parental control features next year
    Washington [US]: Instagram will roll out new parental control features on its platform in March, the service’s head Adam Mosseri has announced in a blog post. According to The Verge, they’ll allow parents and guardians to see how much time their teenagers spend on Instagram, set time limits, and get notified if their child reports someone. The controls were announced as a package of new features designed to make the platform a safer place, particularly for its teenage users.Although Mosseri’s post said these safety features have been in the works for “a long time,” their announcement comes in the wake of a series of damaging revelations about the Meta-owned social network. Most notably, internal documents leaked by whistleblower Frances Haugen showed Instagram was aware that its service can make body image issues worse for its female teenage users. This week, Mosseri is due to testify in front of a Senate committee, where he will likely be asked about the impact of Instagram on its young users, reported The Verge. Alongside the new parental controls, Instagram has said that it’s developing an educational hub for parents and guardians to offer them tips and tutorials about children’s social media use. In the more immediate future, Instagram said it’s rolling out the ‘Take a Break’ feature it started testing last month. This opt-in feature prompts users to step away from the app once they’ve been scrolling for […]
  • Google introduces voice, video call features in Gmail app
    Washington [US]: Google has announced that it has added the ability to join one-on-one Google Chat voice and video calls from within the Gmail app. As per MacRumors, it was possible to make calls from within the Gmail app on iOS and Android, but users had to send an invite to a Google Meet video conferencing call, which was more convoluted and limiting.In future, however, users will be able to tap the new phone and video icons that appear in the upper right corner of individual one-on-one chat screens in the Google Chat section of the app. According to MacRumors, users who initiate a call from the Google Chat app will now be redirected to the Gmail app, highlighting Google’s intention of putting the Gmail app at the centre of its communication platforms. The call feature is rolling out for everyone with Google Workspace, G Suite or personal Google accounts. (ANI)
  • Elon Musk praises Indian talent after Parag Agrawal takes over as Twitter’s CEO

  • Astronomers team up to create new method to understand galaxy evolution
    Washington [US]: A team of astronomers at The University of Toledo joined forces for the first time in their scientific careers during the pandemic to develop a new method to look back in time and change the way we understand the history of galaxies.The resulting breakthrough research published in the Astrophysical Journal outlines their new method to establish the star formation history of a post-starburst galaxy using its cluster population. The approach uses the age and mass estimates of stellar clusters to determine the strength and speed of the starburst that stopped more stars from forming in the galaxy. Until now forging parallel but separate careers while juggling home life and carpooling to cross country meets, Dr Rupali Chandar, professor of astronomy, and Dr J.D. Smith, director of the UToledo Ritter Astrophysical Research Center and professor of astronomy, merged their areas of expertise.Working along with UToledo alumnus Dr Adam Smercina who graduated with a bachelor’s degree in physics in 2015 and is currently a postdoctoral researcher at the University of Washington, they used NASA’s Hubble Space Telescope to focus on a post-starburst galaxy nearly 500 million light-years away called S12 that looks like a jellyfish with a host of stars streaming out of the galaxy on one side.Smercina, the “glue” that brought Smith and Chandar together on this research, worked with Smith as an undergraduate student starting in 2012 on the dust and gas […]
  • Study finds anxiety cues in brain despite safe environment
    Washington [US] : Researchers have used a virtual-reality environment to understand the impact of anxiety on the brain and how brain regions interact with one another to shape behaviour.The findings of the study were published in the journal ‘Communications Biology’. The researchers used a virtual-reality environment where volunteers were in a meadow picking flowers. They knew that some flowers are safe, while others have a bee inside that will sting them.“These findings tell us that anxiety disorders might be more than a lack of awareness of the environment or ignorance of safety, but rather that individuals suffering from an anxiety disorder cannot control their feelings and behaviour even if they wanted to,” said Benjamin Suarez-Jimenez, PhD, assistant professor in the Del Monte Institute for Neuroscience at the University of Rochester and first author of the study.“The patients with an anxiety disorder could rationally say — I’m in a safe space — but we found their brain was behaving as if it was not,” said Benjamin Suarez-Jimenez.Using fMRI, the researchers observed the brain activity of volunteers with general and social anxiety as they navigated a virtual reality game of picking flowers. Half of the meadow had flowers without bees, the other half had flowers with bees that would sting them — as simulated by a mild electrical stimulation to the hand.Researchers found all study participants could distinguish between the safe and dangerous areas, however, brain […]

  • Lack of important molecule in red blood cells causes vascular damage in type 2 diabetes
    Stockholm [Sweden] : Altered function of the red blood cells leads to vascular damage in type 2 diabetes. Results from a new study in cells from patients with type 2 diabetes and mice show that this effect is caused by low levels of an important molecule in the red blood cells.The study by researchers at Karolinska Institutet in Sweden has been published in the journal Diabetes. It is well known that patients with type 2 diabetes have an increased risk of cardiovascular disease. Over time type 2 diabetes may damage blood vessels, which could lead to life-threatening complications such as heart attack and stroke. However, the disease mechanisms underlying cardiovascular injury in type 2 diabetes are largely unknown and there is currently a lack of treatments to prevent such injuries.In recent years, research has shown that the red blood cells, whose most important job is to transport oxygen to bodily organs, become dysfunctional in type 2 diabetes and can act as mediators of vascular complications.In the current study, researchers at Karolinska Institutet have in cells from patients with type 2 diabetes, and mice examined which molecular changes in the red blood cells could explain these harmful effects in type 2 diabetes.The researchers found that levels of the small molecule microRNA-210 were markedly reduced in red blood cells from 36 patients with type 2 diabetes compared with red blood cells of 32 healthy subjects.Micro-RNAs belongs […]
