Science & Technology Current Affairs MCQs

Notes:
Uganda and WHO confirmed an outbreak of Sudan Virus Disease (SVD). It is a viral hemorrhagic fever, related to Ebola, caused by the Sudan virus (SUDV). It was first identified in Sudan in 1976. It exists in animal reservoirs in the region. It has a high fatality rate and spreads through direct contact with bodily fluids or contaminated surfaces. Symptoms start with fever, fatigue, and sore throat, followed by vomiting, diarrhea, rash, and bleeding. There are no approved treatments or vaccines, but early supportive care improves survival chances.

Notes:
Researchers discovered a new type of brain cell called Ovoid cells. These neurons help in recognition memory by differentiating between new and familiar objects. They are named for their egg-like shape and are found in the hippocampus of humans, mice, and other animals. Ovoid cells activate when encountering something new, triggering memory storage. This discovery could help treat brain conditions like Alzheimer’s, Autism Spectrum Disorder, and Epilepsy.

Notes:
Researchers found that bacterial cellulose can be used as a bandage to help plants heal and regenerate faster. It is a natural polymer produced by certain bacteria. It has unique properties that make it effective for plant wound care. Bacterial cellulose bandages offer a sustainable alternative to chemical treatments. This method supports healthier plant growth and eco-friendly farming. It enhances plant healing, leading to better crop yields and resilience. This breakthrough integrates biotechnology into agriculture, promoting sustainable farming and food security.

Notes:
Firefly Aerospace’s Blue Ghost lunar lander successfully landed in the Mare Crisium region of the Moon after a controlled descent. It carries 10 NASA payloads under the Commercial Lunar Payload Services (CLPS) program to boost private-sector lunar exploration. The mission aims to study the lunar environment, using a vacuum for soil collection and a drill measuring temperatures up to 3 meters deep. It will analyze heat flow, plume-surface interactions, and the Moon’s magnetic and electric fields to understand its geological history. The lander will function for 14 Earth days to conduct scientific studies and tech demonstrations.

Notes:
Oscar-winning actor Gene Hackman died of heart disease shortly after his wife, Betsy Arakawa, passed away from hantavirus pulmonary syndrome (HPS). HPS is a rare infectious disease that starts with flu-like symptoms and can cause severe lung and heart issues. It is mainly transmitted by rodents through airborne particles from their urine, droppings, or saliva. Symptoms include fever, fatigue, muscle aches, headaches, and abdominal issues, with a 38% mortality rate if respiratory problems develop. There is no specific treatment, but early medical care can improve survival chances.

Notes:
Scientists confirmed the existence of a fourth form of water, Plastic Ice VII, which forms under extreme conditions. Unlike regular ice, Plastic Ice VII allows water molecules to rotate freely within a rigid crystalline structure. It was first predicted in 2008 and recently proven using neutron-scattering experiments in France. It forms at pressures over 3 GPa (30,000 times Earth’s atmospheric pressure) and temperatures above 450 K (177°C). This discovery helps scientists understand water’s behavior in extreme planetary environments, such as Jupiter’s and Saturn’s moons. It could impact planetary science, materials research, and advanced technology development.

Notes:
Tanzania declared the end of its second Marburg Virus Disease (MVD) outbreak after 42 days with no new cases. MVD was first identified in 1967 in Marburg, Germany, when laboratory workers were exposed to infected green monkeys from Uganda. It is caused by the Marburg virus (MARV), a highly infectious RNA virus from the Filoviridae family, similar to Ebola. The African fruit bat (Rousettus aegyptiacus) is the natural reservoir of the virus, carrying it without symptoms.

Notes:
On March 22, 2025, NASA’s Parker Solar Probe reached 6 million km from the Sun, setting a new record for the closest spacecraft approach. It was launched on August 12, 2018, from Cape Canaveral, Florida. It aims to study the Sun’s corona, solar wind, and magnetic field. The probe follows a highly elliptical orbit, using Venus’ gravity to move closer to the Sun. It is the fastest human-made object, reaching speeds of 692,000 km/hr. It will ultimately come within 6.16 million km of the Sun, about seven times closer than any previous spacecraft.

Notes:
Microsoft announced a quantum computing chip called Majorana 1, aiming to solve industrial-scale problems in years, not decades. The chip is named Majorana 1 because it consists of Majorana particles, which are unique subatomic particles that are their own anti-particles. Neutrinos are a potential Majorana particle and are the second-most abundant subatomic particles after photons. Neutrinos are produced in the Big Bang, supernovae, cosmic rays, and nuclear fusion but are hard to detect. A major unknown in physics is the mass of neutrinos.

Notes:
The government has launched ZooWIN, a digital platform to track real-time availability of anti-rabies vaccines (ARV) and anti-snake venom (ASV) nationwide. ZooWIN is similar to Co-WIN and U-WIN, centralizing data for better coordination among healthcare providers, municipal authorities, and veterinary services. It supports the Union Health Ministry’s efforts to combat rabies and snakebites under the National Action Plan for Prevention and Control of Snakebite Envenoming (NAPSE). India records 3–4 million snakebites annually, causing around 50,000 deaths, half of the global snakebite mortality. The platform is initially piloted in Delhi, Madhya Pradesh, Assam, Puducherry, and Andhra Pradesh.
