6 days, 3 hours ago @ t.meA mushroom that looks just like a tiny tree!Meet Dendrosphaera eberhardtii, a rare fungus from the Trichocomaceae family. It grows in the tropical forests of Southeast Asia — from Indonesia all the way to Okinawa.What looks like a “trunk” is actually the stroma — a thick bundle of fungal threads — and it can reach up to 17 cm tall! At the top, it branches out like a miniature tree, and each “branch” ends with a bright yellow fruiting body.Nature’s craftsmanship at its finest!
1 week, 4 days ago @ t.meAustralia Has More Camels Than Egypt or the UAESurprising as it sounds, Australia is home to the largest population of wild camels in the world — more than Egypt or the UAE. According to various estimates, up to one million wild dromedary camels roam freely across the central and northern parts of the continent.These camels were first brought to Australia in the 19th century from the Arabian Peninsula, India, and Afghanistan. They were used as pack animals to transport goods across the vast deserts. However, with the development of railways and roads, camels became obsolete and were left to roam. In the absence of natural predators and under minimal control, the camel population began to gr…

2 weeks, 6 days ago @ t.mePlants Absorb Microplastics Directly from Air, Raising Concerns Over Food SafetyRecent research has revealed a troubling environmental threat: plants can directly absorb microplastics from the atmosphere, causing plastic particles to accumulate extensively within vegetation. Scientists warn that this phenomenon particularly endangers vegetables grown in open fields.Microplastics (MPs) have already infiltrated every terrestrial ecosystem—present in soil, water, and air alike. Laboratory studies confirm that plant roots uptake microplastics, transferring sub-micron and nano-sized particles from roots up into the shoots.Field measurements, however, have uncovered a more alarming reality: above…
3 weeks, 1 day ago @ t.meOn this day, April 12, we celebrate one of humanity’s greatest milestones—when a human first left our planet and ventured into space. On April 12, 1961, Soviet cosmonaut Yuri Gagarin became the first person to orbit the Earth aboard the spacecraft Vostok 1.His legendary words—“Poyekhali!” (“Let’s go!”)—marked the dawn of the space age and a monumental achievement for science, courage, and international competition. Gagarin’s 108-minute journey turned him into a global icon and opened the door for all future space exploration.Happy Cosmonautics Day!#Gagarin #Space #USSR #science #history
3 weeks, 6 days ago @ t.meHow is communication established between space stations and Earth?Communication from space stations like the International Space Station (ISS) relies on radio signals transmitted through a network of satellites and ground stations. The ISS communicates with Earth using NASA’s Tracking and Data Relay Satellite System (TDRSS). Signals from the ISS are first sent to a TDRS satellite positioned in geostationary orbit. These satellites then relay the information to ground stations located on Earth, such as those in New Mexico (USA). From there, the data is sent to mission control centers like NASA’s Johnson Space Center or ESA’s Mission Control in Europe.The types of communication include voic…
1 week, 3 days ago @ t.meWhat is Google Street View and How does it Work?Google Street View is a technology featured in Google Maps that provides the panoramic views from various streets of the world. It was launched on May 25, 2007 by Google in several cities in the United States, since then it has expanded to many cities and areas of the world. Till today, Google Street View is launched in about 80 countries of the world.Google Street View displays panoramas of the images. For this, Google uses the cars on which high resolution 360 degree cameras are mounted and these cars travels in whole cities and take up photographs of the streets and monuments.Then, these photographs are uploaded by Google for Street View.…
4 weeks ago @ t.meWhat is Chemotherapy and How does it work?Chemotherapy is a drug treatment that uses powerful chemicals to kill fast-growing cells in your body. Chemotherapy is most often used to treat cancer, since cancer cells grow and multiply much more quickly than most cells in the body.Chemotherapy circulates throughout your body in the bloodstream. So it can treat cancer cells almost anywhere in the body. This is known as systemic treatment. Chemotherapy kills cells that are in the process of splitting into 2 new cells. Body tissues are made of billions of individual cells. Once we are fully grown, most of the body's cells don't divide and multiply much. They only divide if they need to repair d…
1 month, 2 weeks ago @ t.meWhy are medicines available in different forms such as capsules, tablets, and liquids?Medicines come in various forms—capsules, tablets, and liquids—based on the drug’s properties, the method of delivery, and patient requirements. Capsules are used when the medicine needs protection from stomach acid or for controlled release over time. They are also preferred for masking the taste of unpleasant drugs or for drugs sensitive to moisture. Tablets are popular because of their stability, precise dosing, and cost-effectiveness. They have a longer shelf life and are easy to mass-produce. In contrast, liquid forms are useful for patients who have difficulty swallowing or when rapid absorption is…
2 months ago @ t.meWhat is Jet lag?Jet lag is a temporary sleep disorder that occurs when a person rapidly travels across several time zones, causing a disruption in the body’s internal clock, also known as the circadian rhythm. The circadian rhythm controls essential bodily functions such as sleep, digestion, and hormone release based on a 24-hour cycle. When this internal clock is misaligned with the local time at the destination, it leads to jet lag.The most common symptoms of jet lag include fatigue, daytime sleepiness, and insomnia. Individuals may struggle to fall asleep at the appropriate time, often waking up too early or feeling excessively tired even after sleeping. Other symptoms include difficul…
2 months, 1 week ago @ t.meHow does a life saving jacket works?A life-saving jacket, also known as a personal flotation device (PFD), works by providing buoyancy to keep a person afloat in water, preventing drowning. It is typically made from lightweight, buoyant materials like foam or has inflatable air chambers. These materials are less dense than water, displacing water and producing an upward buoyant force that counters the body’s natural downward pull due to gravity.The key principle behind a life jacket’s operation is Archimedes’ principle, which states that a body immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced. When a person wearing a life jacket enters water, the jack…
