Photo by  cottonbro  from  Pexels Research conducted at the University of Bristol  in the U.K., suggests that watching TV for four hours or more can increase the risk of blood clots. For prolonged viewers, the chances are 35% more as compared to those who watch TV for 2.5 hours or less.  “Our study findings also suggest that being physically active does not eliminate the increased risk of blood clots associated with prolonged TV watching,” said Dr. Setor Kunutsor , lead author of the study. “If you are going to binge on TV you need to take breaks. You can stand and stretch every 30 minutes or use a stationary bike. And avoid combining television with unhealthy snacking,” he added. The study assessed the connection between watching TV and Venous Thromboembolism (VTE), a condition in which blood clots form in the deep veins of the leg. Complications occur when some part of the clot travels through the blood in the lungs causing pulmonary embolism. In the current study, researchers collec

Geneva Study Shows Playing Action Video Games Increases School Children's Attention by Sevenfold

Photo by  JESHOOTS.com  from  Pexels Decoding letters into sounds is an important part of learning to read, but it is not sufficient for mastering the process. Recently, a video game was created that blends action video games with mini-games that teach several executive functions such as working memory, inhibition, and cognitive flexibility, all of which are used while reading. The goal is to recreate the elements of an action game while avoiding the use of violence , making it suitable for young children. Daphné Bavelier , a professor in the Psychology Section of the Faculty of Psychology and Educational Sciences (FPSE) at the University of Geneva points out that “Reading calls upon several other essential mechanisms that we don’t necessarily think about, such as knowing how to move our eyes on the page or how to use our working memory to link words together in a coherent sentence.” Angela Pasqualotto , first author of this study, explains “These other skills, such as vision, the dep

New Study Shows Aphid ‘Honeydew’ Promotes Bacteria That Can Kill Them

During the study, researchers used  Pseudomonas syringae, a type of bacteria that resides on leaves . Pseudomonas syringae is a rod-shaped bacteria that infect a wide range of plant species. It also affects certain infection carriers like Aphids that transfer the infection while feeding on the sap, damaging crops of billions of dollars around the world. The research shows how certain strains or genetic types of Pseudomonas syringae are infectious to aphids and might also be used to control pests. The research paper, “ Context-Dependent Benefits of Aphids for Bacteria in the Phyllosphere ,” published in the journal ‘The American Naturalist,’ assessed the virulence (micro-organisms ability to damage the host) of different strains (genetic ty

Sleep Is Vital to Remember People's Faces and Names Shows Recent Study

Image
Photo by  Acharaporn Kamornboonyarush  from  Pexels According to recently published study by Northwestern University, when people's memories of freshly taught face-name connections were reactivated while they were sleeping, researchers discovered that their name recall improved dramatically. Uninterrupted deep sleep was crucial to this progress. Nathan Whitmore, a PhD candidate in the Interdepartmental Neuroscience Program at Northwestern said, “It’s a new and exciting finding about sleep, because it tells us that the way information is reactivated during sleep to improve memory storage is linked with high-quality sleep .” Memory reactivation did not benefit and may even be harmful to study participants with EEG data (a recording of electrical activity in the brain picked up by electrodes on the scalp) that indicated interrupted sleep. The reactivation resulted in a relative improvement of a little over 1.5 more names recalled in those who slept uninterrupted throughout the specif

Photo by  Angeli Ann Dinsay  from  Pexels Nathan Morehouse , associate professor at the University of Cinncinati, examined a common jumping species of spider, Saitis barbipes , found in Europe and North America. The males of this species have furry red crowns and legs. They perform courtship dances to attract their female counterparts. "We assumed they were using colour for communication. But we didn't know if their visual system even allowed them to see those colours," said David Outomoro , a researcher associated with the study. The biologists collected spiders for lab study in Germany. They used microspectrophotometry to identify the sensitivity of their photoreceptors (light-sensing cells) towards the light of different colours and wavelengths . But, they found no evidence for red photoreceptors.  Microspectrophotometry is a technique used to measure the absorption and transmission of a light spectrum. This can be measured through a microspectrophotometer. Here, the t

China's Chang'E-5 Moon Lander Has Returned With Samples That Contain Water

Photo by  GEORGE DESIPRIS  from  Pexels Water is a valuable resource in deep space, along with being a sign of possible life. There are numerous things that astronauts do in space and water is important for a few among those. It is also essential for astronaut landings, survival, and other purposes such as the production of rocket fuel. Researchers in China discovered the first signs of the  presence of water on the moon’s surface . This was done with help of the data obtained from Chang’E-5 lander’s lunar mineralogical spectrometer (LMS).  Professors  LIN Yangting and LIN Honglei of the Chinese Academy of Sciences' Institute of Geology and Geophysics (IGGCAS) were the ones who made the discovery. The study also included researchers from CAS's National Space Science Center, the University of Hawai'i at Mānoa, CAS's Shanghai Institute of Technical Physics, and Nanjing University.

Image credit: University of Minnesota                                       The researchers at the University of Minnesota Twins Cities have developed a fully 3D-printed, flexible OLED display using a customised printer that can print objects for you. This finding can help to produce low-cost OLED displays in the coming years, instead of technicians using costly microfabrication facilities to construct small-scale structures such as computer chips, smartphone displays, etc. The detailed study is published in Science Advances . OLED Technology- Overview OLED stands for Organic Light-Emitting Diode- a technology that uses LEDs to produce light by organic molecules. This technology helps to create the world’s best display panels. Organic displays are prepared by placing thin films of organic semiconductors such as silicon or gallium arsenide between two conductors. These films emit a bright light when an electric current is applied. Each pixel emits its own light and is controlled indivi

New Research Shows That Dogs Can Differentiate Between Different Human Languages

Photo by  Pixabay  from  Pexels Without a shadow of a doubt, dogs are humanity's best friend. The close association over several centuries may have also given them an extraordinary ability to understand human languages. New research published in the journal, NeuroImage has revealed that dogs can actually distinguish between different human languages. The research was conducted by  Laura Cuaya , a neurobiologist at Eötvös Loránd University , and her team in Hungary.  Analyses of Dogs' Auditory Abilities Cuaya and her team trained 18 dogs including Kun-Kun (Cuaya's own pet), to lie motionless inside the MRI machine so their brains could be scanned while listening to the audio recordings of the human speech.  A dog trained to lie motionless for a MRI scan.

In the machine, each dog was exposed to an excerpt from a popular children's book, ‘The Little

Scientists conducted an experiment in the lab that explains why the Sun is sooooo hot!

Source: Solar Dynamics Observatory, NASA One of the major mysteries of solar physics is why the Sun's corona, the outermost part of its atmosphere reaches temperatures of several million degrees Celsius . A "hot" path leading to a region of the solar atmosphere just below the corona, where sound waves and certain plasma waves move at the same speed, explains this effect. A team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) , a German national lab, developed a laboratory model and for the first time experimentally confirmed the theoretically predicted behaviour of these plasma waves – called Alfvén waves. This was done in an experiment using the molten alkali metal rubidium and pulsed high magnetic fields, as reported in the journal Physical Review Letters. In solar physics, it is now comm

The Dragon spacecraft separated from Falcon 9 and landed autonomously on the space station on Wednesday, December 22 2021, around 4:30 a.m., and will remain there for a month. Among the 6500 pounds of materials that the spacecraft launched from the Kennedy Space Center in Florida were supplies for the crew, a skin bioprinter, and even a detergent . Skin Bioprinting Bandages Skin bioprinting is a new approach for creating artificial skin from natural and synthetic building blocks. This process uses biological molecules and cell viability (a measure of live and healthy cells in a population) to print tissue structures. Skin reconstruction via burns is one of the applications of bioprinting that has been developing in the past years. However, it still needs a large bioprinter to print a tissue, allow

Scientists Use Lice Nits to Find More About Ancient Mummies and Their Lifestyle

In a recently published study, DNA was extracted for the first time from cement on hairs obtained from mummified corpses dating back 1,500-2,000 years. As female lice attach eggs, known as nits, to the hair, skin cells from the scalp also get enclosed in the cement made by female lice, saving them from decay for a considerable period. The University of Reading led the study, which also included other researchers from Argentina, Wales and Denmark. The findings of the study were published in  Molecular Biology and Evolution .

                                   Photo by Pixabay from Pexels A recent study conducted at Texas A&M University has shown that college students are addicted to smartphones, have higher levels of screen time and access multiple devices frequently compared to previous generations. Due to the increased use of these gadgets, especially tabs and smartphones, students are more likely to shift towards a comfortable workplace such as a couch or chair with no desk that leads to musculoskeletal disorders like low back pain, sprains, and strain at a very young age. According to the 2021  Statista  report, the present number of smartphone users on the planet is 6.37 billion, which means 80.63% of the human population owns a smartphone. The figure rose from 2016 when the number of users was 3.66 or roughly 50% of the global population. With the hike in the number of smartphone users, a large population is expected to suffer from musculoskeletal disorders like low back pain due to incorrect
