Methane Latest News
According to the International Energy Agency’s (IEA) Global Methane Tracker 2025, the energy sector contributed approximately 145 million tonnes (Mt) of methane emissions in 2024, with oil and gas facilities alone accounting for over 80 Mt.

About Methane
- Methane is a potent greenhouse gas, responsible for about 30% of the global temperature rise since the Industrial Revolution. Its atmospheric concentration is now 2.5 times higher than in the preindustrial era and is rising faster than other greenhouse gases.
- The three major anthropogenic sources of methane emissions are agriculture, energy, and waste sectors.
- The energy sector — comprising oil, natural gas, coal, and bioenergy — accounts for over 35% of human-induced methane emissions.
- Within the energy sector:
- Oil operations contributed around 45 Mt.
- Natural gas operations released nearly 35 Mt.
- Abandoned oil and gas wells emitted approximately 3 Mt.
- Coal activities added more than 40 Mt, including 4 Mt from abandoned mines.
- Bioenergy combustion, especially in developing countries, contributed 18 Mt, mostly from traditional biomass like wood, dung, and charcoal.
- Methane Characteristics:
- It is a colourless, odourless, and highly flammable gas, also known as marsh gas.
- It has a short atmospheric lifespan of ~10 years but a Global Warming Potential (GWP) of ~80 times that of CO₂ over 20 years.
- Around 60% of atmospheric methane comes from human activities; the rest is from natural sources like wetlands and permafrost thawing, which release methane and CO₂ as temperatures rise.
- End-use equipment in energy systems also leaks methane — contributing an additional 2 Mt.
- Modern bioenergy sources contributed ~2 Mt of methane. These include biogas, biomethane, and biofuels derived from plant residues and waste.
- The IEA highlighted that ~70% of fossil fuel methane emissions can be mitigated using existing technologies, and in oil & gas, ~75% of emissions can be reduced by fixing leaks and plugging abandoned wells.
- China, followed by the USA, Russia, Iran, Turkmenistan, and India, are the top emitters from fossil fuel operations.
Methane FAQs
Q1: What is methane, and why is it significant in climate discussions?
Ans: Methane (CH₄) is a potent greenhouse gas, with a global warming potential about 80 times greater than CO₂ over 20 years.
Q2: What are the major sources of methane emissions?
Ans: Major sources include livestock digestion (enteric fermentation), rice paddies, landfills, and oil and gas operations.
Q3: Which global initiative targets methane reduction?
Ans: The Global Methane Pledge, launched at COP26, aims to reduce global methane emissions by at least 30% by 2030.

MADMAX Latest News
The MADMAX collaboration has published the first results of its search for dark photons using a prototype detector.

What is MADMAX?
- MADMAX stands for Magnetised Disk and Mirror Axion Experiment.
- It is a research initiative designed to detect dark matter candidates such as axions and dark photons.
- The detector consists of a stack of dielectric (sapphire) disks and a reflective mirror, forming a resonator system.
What are Dark Photons?
- Dark photons are hypothetical particles similar to photons (light particles) but with mass.
- They are proposed components of galactic dark matter halos.
- Under specific conditions, dark photons can convert into ordinary photons, with the frequency of conversion depending on the mass of the dark photon.
How does the MADMAX Detector Work?
- The core detection mechanism involves boosting the conversion of dark photons to microwave photons.
- This is achieved using a resonator composed of parallel dielectric disks that enhance conversion probabilities.
- A curved mirror focuses the resulting microwave signals into a horn antenna that connects to a microwave receiver.
Key Features of the MADMAX Setup
- Resonators larger than the wavelength of expected dark photon signals, enabling detection at higher frequencies (~20 GHz).
- Ability to tune resonance frequencies by adjusting disk positions, thereby expanding the mass range coverage.
- Signal identification relies on detecting a narrow peak in Fourier space that stands out from thermal noise.
Experimental Findings
- The first prototype run did not detect dark photon signals.
- However, the instrument functioned successfully, detecting signals with a sensitivity three orders of magnitude better than prior methods.
- This run covered a previously unexplored range of parameters in just one experiment.
MADMAX FAQs
Q1: What are axions?
Ans: Axions are hypothetical elementary particles proposed to solve the strong CP problem in quantum chromodynamics (QCD).
Q2: Why are axions significant in physics?
Ans: They are strong candidates for cold dark matter, which is believed to make up most of the universe’s mass.
Q3: What are dark photons?
Ans: Dark photons are theoretical particles that may mediate interactions in the dark matter sector, similar to how regular photons mediate electromagnetic interactions.

Lupus Latest News
World Lupus Day is celebrated every year on May 10 to raise awareness about this rare but severe disease.

About Lupus
- It is a disease that occurs when your body's immune system attacks your own tissues and organs (autoimmune disease).
- Inflammation caused by lupus can affect many different body systems — including your joints, skin, kidneys, blood cells, brain, heart, and lungs.
- Causes: The cause of lupus is unknown. It’s thought to be the result of a mix of genetic, hormonal, and environmental factors.
- Lupus is much more common among women than men.
- There are several kinds of lupus:
- Systemic lupus erythematosus (SLE) is the most common type. It can be mild or severe and can affect many parts of the body. SLE accounts for 70% of lupus cases.
- Discoid lupus causes a red rash that doesn't go away.
- Subacute cutaneous lupus causes sores after being out in the sun.
- Drug-induced lupus is caused by certain medicines. It usually goes away when you stop taking the medicine.
- Neonatal lupus, which is rare, affects newborns. It is probably caused by certain antibodies from the mother.
- Symptoms:
- Lupus causes symptoms throughout your body, depending on which organs or systems it affects.
- Everyone experiences a different combination and severity of symptoms.
- The symptoms of lupus occur in times of flare-ups. Between flare-ups, people usually experience times of remission, when there are few or no symptoms.
- The wide range of symptoms in the body includes joint pain, headache, rashes, fever, fatigue, mouth sores, confusion, swollen glands, and blood clots, among others.
- Treatment: There is no cure for lupus, but medicines and lifestyle changes can help control it.
