Animals that went into the space before humans did
animals in space
is a fascinating one, filled with bravery, sacrifice, and scientific discovery.
According to NASA's history of animals in space, the first animals were launched into space in the 1940s and 1950s. Scientists also sent monkeys, chimps, and dogs into space to assess the feasibility of travel and ensure their safe return. These early missions provided critical data on biological responses to spaceflight, paving the way for human exploration. Over time, the variety of animals expanded to include mice, turtles, and even insects, each helping to answer new scientific questions.

Belka and Strelka: In 1960, Belka and Strelka, two Soviet space dogs, became the first animals to orbit the Earth and return safely. Their successful mission marked a significant breakthrough in space exploration.
2. Monkeys
Albert II: In 1948, Albert II, a rhesus macaque, became the first primate in space. Launched by the United States, Albert II's flight reached an altitude of 83 miles. The V-2 rocket carrying Albert II was a significant milestone in the exploration of space and the study of the effects of space travel on living organisms. Unfortunately, Albert II did not survive the flight, dying on impact due to the failure of the parachute system.
Ham the Chimp: In 1961, Ham, a chimpanzee, became the first of his kind in space. Launched on a Mercury-Redstone rocket, Ham's suborbital flight lasted 16.5 minutes, including 6.6 minutes of weightlessness. Despite technical issues, Ham performed well and came down safely.

Enos: Enos, a chimpanzee, became the first primate to orbit the Earth in 1962. Launched as part of the Mercury program, Enos's mission demonstrated the feasibility of orbital spaceflight.
Gordo: In 1958, Gordo, a squirrel monkey, embarked on a groundbreaking journey aboard a Jupiter rocket. Reaching an altitude of 600 miles, Gordo's flight marked a significant milestone in space exploration. He tragically lost his life due to a malfunctioning flotation device, but his mission provided crucial insights. Navy doctors analysed signals from Gordo's respiration and heartbeat monitors, concluding that humans could potentially withstand similar space travel conditions.
3. Spiders
Spiders: In 1973, the effects of zero gravity on web spinning behavior were studied by sending two European garden spiders into space. Studying the spider's ability to adapt to microgravity environments provided valuable insights into the consequences of space travel on living organisms.
4. Reptiles and amphibians
Tortoises: In 1968, two Russian tortoises orbited the moon with wine flies and mealworms and were the first animals to orbit the moon. The tortoises survived the journey, and the study provided valuable insight into the consequences of space travel on living organisms.

Nematode Worms: Nematode worms have been the subject of space research, on which many conclusions have been drawn regarding the effect of microgravity on the development and behavior of this species. These little creatures have made a significant contribution to the consequences of space travel on living organisms.
6. Mice
In 1959, four black mice were launched on Discoverer 3, a US spy satellite mission. Unfortunately, the mice died when the Agena upper stage malfunctioned, causing the vehicle to crash into the Pacific Ocean. This mission was notable for being the only Discoverer flight with an animal payload.

NIT Rourkela study cracks protein puzzle for stronger bone repair
Researchers at the National Institute of Technology (NIT) Rourkela have found how certain natural sugar-like molecules in human body can change the way a key bone protein behaves. The work, published in the journal Biochemistry, offers clues for improving bone and cartilage repair treatments, designing better medical implants, and developing more effective protein-based are workhorses in the human body, building tissues, carrying signals, and supporting chemical reactions. For these roles, proteins must fold into specific three-dimensional in their structure can affect how well they work. Understanding how and why a protein unfolds is a long-standing challenge in biology, with applications ranging from drug delivery to tissue ROURKELA MAPS SUGAR-PROTEIN LINK FOR BETTER BONE REPAIR METHODS The study focused on Bone Morphogenetic Protein-2 (BMP-2), a molecule central to bone and cartilage formation. BMP-2 also helps stem cells turn into bone-forming cells and supports healing after the body, BMP-2 operates in an environment rich in glycosaminoglycans (GAGs), sugar-like molecules found in connective tissue and joint fluids. The NIT Rourkela team, led by Professor Harekrushna Sahoo from the Department of Chemistry, examined how different GAGs affect BMP-2 under chemical scholars Devi Prasanna Behera and Suchismita Subadini worked alongside him in the study. The team used urea to induce unfolding and compared the behaviour of BMP-2 with and without results showed that in the presence of Sulfated Hyaluronic Acid (SHA), a type of GAG, BMP-2 unfolded faster than it did with regular hyaluronic acid or without any study suggests that SHA binds directly to BMP-2, altering its structure in a way that makes the unfolding process more Sahoo explained that BMP-2 functions within a GAG-rich environment in bone tissue, and these molecular interactions shape its structure and understanding these interactions, it may be possible to design scaffolds that keep BMP-2 in its active form for longer, reduce the dosage needed in treatments, and limit side research also points to a broader idea, modifying the functional groups of GAGs, such as through targeted sulfation, could help stabilise proteins like BMP-2 under stress without losing their could guide the creation of new drug formulations, extend protein shelf life, and make therapeutic delivery more mapping these detailed molecular relationships, the NIT Rourkela study provides a framework for future work in regenerative medicine, where fine-tuning the environment around proteins can be as important as the proteins themselves.- Ends

Man suffers rare bromism following ChatGPT diet tips. All about dangerous condition and its symptoms
A case of bromism has come to light after a man developed this rare condition following an interaction with ChatGPT about removing table salt from his diet. An article in the Annals of Internal Medicine reported a case in which a 60-year-old man developed bromism, also known as bromide toxicity , after consulting Chatgpt, according to Guardian. The article described bromism as "ingestion of bromide can lead to a toxidrome known as bromism. "While this condition is less common than it was in the early 20th century, it remains important to describe the associated symptoms and risks, because bromide-containing substances have become more readily available on the internet," it read.

Comedian startling relocation hint shocks fans What is bromism? The man told doctors that after reading about the negative effects of sodium chloride, or table salt, he consulted ChatGPT about eliminating chloride from his diet and started taking sodium bromide over a three-month period. This was despite reading that 'chloride can be swapped with bromide, though likely for other purposes, such as cleaning'. Sodium bromide was used as a sedative in the early 20th century. On admission, the patient shared that he maintained multiple dietary restrictions and that he distilled his own water at home. He was noted to be very thirsty but paranoid about water he was offered. Live Events According to the journal, Bromide toxicity, or bromism, was once a well-recognized toxidrome in the early 20th century that precipitated a range of presentations involving neuropsychiatric and dermatologic symptoms. Bromism was thought to have contributed to up to 8% of psychiatric admissions at that time, as bromide salts were found in many over-the-counter medications targeting a wide array of indications, including insomnia, hysteria, and anxiety. ALSO READ: DOGE price forms golden cross for the first time since Nov 2024. Could a massive 300% surge be next? "The incidence of bromism declined dramatically when the U.S. Food and Drug Administration eliminated the use of bromide between 1975 and 1989 (3). However, case reports of bromism have reemerged within recent years, including from dietary supplements, bromide-containing sedatives, and excess dextromethorphan. While cases of bromism may remain relatively rare, it remains prudent to highlight bromism as a reversible cause of new-onset psychiatric, neurologic, and dermatologic symptoms, as bromide-containing substances have become more readily available with widespread use of the internet," according to the journal. Bromism was diagnosed as the lab results of the patient were weird and his blood shows what looks like high chloride levels.

Bromide intoxication happens when too much bromide — a chemical element related to chlorine — builds up in your body. You won't find bromide normally in your everyday food items but it can still get into your system from certain medications, supplements, or imported products. What's the problem with bromide? Your body doesn't get rid of bromide super quickly. It competes with chloride (yes, like in table salt) for space in your cells. When bromide sticks around, it starts messing with your nervous system. The symptoms of bromism headaches, confusion, memory problems, dizziness, slurred speech, tremors, and in severe cases, hallucinations or psychosis. Because the symptoms are vague, people sometimes go months without realizing bromide is the culprit.
