Plasti-Ice
- Scientists confirmed the existence of Plastic Ice VII, a fourth form of water.
- It’s a unique phase where water molecules rotate freely within a rigid crystalline structure.
- This phase was predicted in 2008 and confirmed using neutron scattering experiments.
- It forms under extreme conditions: pressures exceeding 30,000 times Earth’s atmospheric pressure and temperatures above 177°C.
- The discovery uses quasi-elastic neutron scattering (QENS) and diamond-anvil cells.
- Plastic Ice VII’s molecules rotate in specific directions.
- This discovery has implications for planetary science, particularly in understanding icy moons (e.g., Callisto, Ganymede, Titan).
- It could help scientists explore whether extreme planetary conditions support life and how water affects celestial body structures.
- The discovery could also have applications in materials science and futuristic technologies.

Kyrgyz-Tajik Border
-
Kyrgyzstan and Tajikistan have finalized a land swap agreement to resolve their long-standing border dispute. This ends decades of conflict stemming from poorly defined borders inherited from the Soviet era.
-
The agreement involves Kyrgyzstan gaining roughly 25 square kilometers of land from Tajikistan in exchange for other territories. This exchange improves access to water resources and farmland for both countries.
-
Several previously contested roads will become jointly accessible, and access to oil wells will be eased.
-
The deal includes provisions for relocating residents from villages affected by the land swap, with some villages being rebuilt. Access to a vital agricultural canal will also be improved.
-
The agreement follows a period of heightened tensions, including deadly clashes in autumn 2022. A meeting between the Kyrgyz and Tajik presidents in 2023 at a UN summit fostered optimism for a resolution.
-
The deal signifies an improvement in relations between the two countries and contributes to a broader trend of warming relations among the five Central Asian ex-Soviet republics. The final agreement will be signed by both presidents after parliamentary review and ratification.

The significant number of registrations highlights the portal’s increasing reach and potential impact on social security coverage for India’s vast unorganized workforce. The integration with various schemes streamlines benefit delivery.
Early Toolkit
- Recent discoveries push back the timeline of bone tool use to 1.5 million years ago, a million years earlier than previously thought.
- This challenges the long-held belief that toolmaking was uniquely human.
- Earliest stone tools date back 3.3 million years, further indicating tool use predates the Homo genus.
- The ability to make tools was once considered evidence of superior human intellect (“Man, the tool-maker”).
- Chimpanzees and other primates have been observed using and modifying tools in the wild, challenging the human-exceptionalism narrative.
- Lucy, a 3.2-million-year-old hominin, may have possessed the hand dexterity for tool use, despite stone tools being discovered later.
- Archaeological evidence shows stone tool use for meat processing and bone marrow extraction by hominins before 3.39 million years ago.
- The study of primate hand morphology suggests that precision dexterity and tool use might have been present in the last common ancestor of all great apes 13 million years ago.
- The timeline of tool technology remains imprecise, but evidence points to its origins much earlier than previously believed, predating the Homo genus and challenging the notion of human uniqueness in this regard.

Hydrogen Peroxide
-
Researchers developed a new, eco-friendly method for synthesizing hydrogen peroxide (H₂O₂) using a hydrazone-linked Covalent Organic Framework (COF).
-
This method is more efficient and energy-saving than conventional methods.
-
The COF enables H₂O₂ production under visible light, eliminating the need for external reagents.
-
H₂O₂ is a versatile chemical with uses as an antiseptic, disinfectant, bleaching agent, rocket propellant, and in food processing.
-
Current industrial production of H₂O₂ is energy-intensive and produces hazardous byproducts.
-
The new method uses sunlight, making it a sustainable alternative.
-
The hydrazone-linked COF shows exceptional photocatalytic H₂O₂ production, outperforming most organic photocatalysts under similar conditions.
-
A significant amount of H₂O₂ was produced under sunlight irradiation (550 μmol g⁻¹ h⁻¹).
-
Using a water-benzyl alcohol solution further enhances H₂O₂ production (up to 21641 μmol g⁻¹ h⁻¹), paving the way for continuous flow reactors.
-
This breakthrough offers a cleaner and more sustainable pathway for H₂O₂ production, potentially revolutionizing industrial processes.
-
The research was conducted at the S. N. Bose National Centre for Basic Sciences, Kolkata.

North Sea
-
A cargo ship carrying toxic chemicals (including sodium cyanide) collided with a US military oil tanker in the North Sea.
-
The incident occurred 16km off the coast of Hull, UK, on March 10, 2025.
-
A large fire resulted, with one crew member missing and another hospitalized. The search for the missing crew member was called off.
-
The collision raised concerns about environmental damage due to the release of chemicals and jet fuel.
-
Experts noted that while jet fuel evaporates quickly, the sodium cyanide and smoke pose significant risks to marine life and the ecosystem, particularly near a harbor porpoise breeding ground.
-
The incident occurred in a busy shipping lane, prompting questions about navigational safety and procedures. Initial investigations suggest no foul play, but this hasn’t been ruled out.
-
The Maritime and Coastguard Agency is assessing the situation and coordinating pollution response efforts. The Port of Grimsby expressed concern over the incident.
-
The North Sea is a vital trade route and rich in oil and gas resources, highlighting the risks associated with heavy maritime traffic in the region.
North Sea
-
Collision in the North Sea: A cargo ship carrying toxic chemicals collided with a US military jet fuel tanker on March 10, 2025, raising environmental concerns.
-
Location: The incident occurred 16 km off the coast of Hull, UK, a significant port and fishing area.
-
Vessels Involved: The Portuguese-flagged Solong (carrying sodium cyanide and alcohol) and the US-registered Stena Immaculate (carrying jet fuel).
-
Casualties: 36 people rescued, one crew member missing (later declared lost).
-
Environmental Concerns: Sodium cyanide’s toxicity and potential jet fuel impact on marine life, particularly near a harbor porpoise breeding ground, are major worries. Though jet fuel is considered less environmentally damaging than crude oil, the smoke and any spill poses risks.
-
Investigation: Authorities are investigating the cause of the collision, questioning how it could occur in daylight despite modern navigation systems. Foul play hasn’t been ruled out.
-
North Sea Significance: The North Sea is a strategically important area with significant oil and gas reserves, offshore wind farms, fisheries, and major shipping routes. It borders several European countries including the UK, Germany, Netherlands, and others.
-
Response: The UK’s Maritime and Coastguard Agency is assessing pollution risks and leading the response effort.
Fuego’s Fury
-
Volcán de Fuego eruption: A recent powerful eruption in Guatemala sent pyroclastic flows and incandescent material towards nearby communities.
-
Location and type: Volcán de Fuego is a stratovolcano overlooking Antigua, Guatemala, part of the Pacific Ring of Fire.
-
Frequent activity: Guatemala experiences frequent seismic and volcanic activity due to its location on the Ring of Fire. Fuego is one of Central America’s most active volcanoes.
-
History of eruptions: Volcán de Fuego has a long history of violent eruptions, including a deadly 2018 eruption that killed 194 and left 234 missing.
-
Eruptive style: Characterized by explosive events, lava flows, and hazardous pyroclastic flows.
-
Stratovolcano characteristics: Tall, steep, cone-shaped volcanoes formed by layers of lava and pyroclastic material. They’re typically found above subduction zones and are common in volcanically active regions.
-
Composition: Mostly andesite and dacite lavas (cooler, more viscous than basalt), leading to explosive eruptions due to gas pressure buildup.
-
Guatemala’s risk: The frequent volcanic activity poses a significant risk to nearby communities.
