What are Diatoms?
A team of Indian and international researchers discovered a new species of diatom, named Climaconeis heteropolaris.

About Diatoms:

  • These are photosynthetic, single-celled organisms.
  • These are microscopic algae and serve as the base of the aquatic food chain.
  • They are a major group of algae and form one of the most common forms of phytoplankton.
  • Habitat:
    • They are found in almost all aquatic habitats, including lakes, ponds, streams, rivers, and the ocean.
    • Most diatoms live as free-floating cells in the open water, but some live on the bottom (benthos), attached to surfaces such as plants or rocks, or in the bottom sediment.
    • These surface-attached diatoms represent a significant part of the periphyton, which is a mixture of algae, cyanobacteria, microbes, and detritus that is attached to submerged surfaces.
  • Due to their sensitivity towards any water chemistry changes, they are excellent indicators of aquatic health.
  • Like other algae, diatoms have no leaves, stems, roots, or flowers, but the cell of every diatom contains chlorophyll, the substance that is responsible for the green color of leafy plants.
  • They are the only organism on the planet with cell walls composed of transparent, opaline silica.
  • Diatom cell walls are ornamented by intricate and striking patterns of silica.
  • Each species has a distinct pattern of tiny holes in the cell wall (frustule) through which they absorb nutrients and get rid of waste.
  • Diatoms can photosynthesize which means they can convert dissolved carbon dioxide in the water into oxygen that is essential for the survival of fish and other aquatic organisms.
  • They also serve as a major source of atmospheric oxygen for the planet, and a key food source for higher organisms in the food chain, such as zooplankton, molluscs, and fish.
  • Collectively, they are responsible for generating up to 50% of the oxygen produced globally each year.
  • Diatoms also play a crucial role in the nutrient cycling of marine and lake waters.

Key Facts about Mashco Piro Tribe
The Mashco Piro tribe, an uncontacted group in the Peruvian Amazon, has been sighted near a village, raising concerns about logging activities encroaching on their territory.

About Mashco Piro Tribe:

  • The Mashco-Piro, or Mascho Piro, also known as the Cujareño people and Nomole, are an indigenous tribe of nomadic hunter-gatherers who inhabit the remote regions of the Amazon rainforest.
  • They live deep in the rainforests of southeast Peru close to the border with Brazil and Bolivia.
  • They are believed to have fled into the recesses of the jungle during the Amazon Rubber Boom in the late 1800s, a time of enslavement and death for many tribes.
  • They live on the banks of the Las Piedras River in the Alto Purús National Park in huts constructed of palm leaf. In the rainy season, they retreat to huts in the rain forest.
  • Their movements across their territory are highly dynamic, dictated by dry and rainy seasons.
  • They speak a dialect of the Piro language.

What is E-20 Fuel?
India’s auto industry lobby has said that carmakers will continue to honour warranties even if older vehicles, not originally designed for higher ethanol fuels use E20 fuel.

About E-20 Fuel:

  • Automotive fuel blends comprising 20% ethanol and 80% gasoline are referred to as E20 fuel.
  • What is Ethanol Blending?
    • Ethanol blending is a process of mixing or blending ethanol, a renewable biofuel, with petrol to create a cleaner and more sustainable fuel.
    • Since ethanol is a viable biofuel that can be derived by processing biomass sources such as sugarcane, the practice of ethanol blending has largely reduced India’s dependence on fossil fuels and the high-value import of crude oil.
    • Moreover, by adding ethanol to petrol, the oxygen content of fuel is increased, leading to lower emissions and cleaner burning.
    • Additionally, since ethanol in India is largely derived from sugarcane molasses, rice, maize, and other agricultural sources, ethanol blending has also elevated the agricultural sector in India.
    • With ethanol-blended petrol, India aims to tackle its ever-increasing fossil fuel dependence in a greener and more sustainable way.
  • India’s Journey of Ethanol Blending:
    • With several countries widely adopting ethanol blending, India’s journey towards achieving ethanol-blended petrol began in 2003, when the Government of India officially launched its Ethanol Blended Petrol (EBP) Programme.
    • Since then, the ethanol blending in India has come a long way, achieving a 10% ethanol blend target in 2021-22, which was further increased to 12.06% in 2022-23, 14.06% in 2023-24, and 20% in July 2025, which was initially set to be achieved by 2030.

What is ethanol?

  • Ethanol, also known as ethyl alcohol, is a type of alcohol that is commonly used in various applications.
  • It is a clear, colourless liquid with a characteristic odour and taste.
  • Ethanol has the chemical formula C2H5OH and is composed of carbon, hydrogen, and oxygen
  • Pure ethanol is nontoxic and biodegradable, and if spilled, they break down into harmless substances.
  • However, fuel ethanol contains denaturants to make fuel ethanol undrinkable.
  • How is ethanol sourced?
    • Ethanol can be produced from various sources, but it is often derived from renewable resources such as crops like corn, sugarcane, barley, and wheat.
    • It can also be produced from cellulosic materials like agricultural residues and wood.

Mitochondrial Protein Import
Recently, researchers at Caltech University have uncovered new rules governing mitochondrial protein import, revising the long-standing understanding of how proteins are transported into mitochondria.

About Mitochondria

  • Mitochondria are double-membraned organelles that generate ATP (adenosine triphosphate), the universal cellular energy currency.
  • They originated over a billion years ago through endosymbiosis between a primitive archaeal cell and a bacterium.
  • Over time, mitochondria transferred most of their genes to the host nucleus, making them dependent on the host cell for protein supply.

Traditional Model of Protein Import

  • Earlier, it was believed that mitochondrial proteins are imported only after translation is completed in the cytosol.
  • Proteins were thought to fully synthesize on ribosomes before passing through mitochondrial membrane channels.

New Findings by Caltech Scientists

  • Around 20% of mitochondrial proteins are cotranslationally imported, i.e., they are imported while still being synthesized by ribosomes.
  • This mechanism mainly applies to large and structurally complex proteins that require assistance during folding.
  • If these proteins fully fold in the cytosol, they risk forming irreversible structures that block import channels.

Mechanism of Cotranslational Import

  • Such proteins contain a mitochondrial targeting sequence, but this alone is insufficient for cotranslational delivery.
  • A second signal is required – the first large protein domain that emerges during translation.
  • This domain acts like a “code to unlock the boarding pass”, ensuring the protein is guided into mitochondria early.
  • Experiments confirmed that transplanting these domains onto other proteins rerouted them for cotranslational import.

Crocothemis erythraea
Recently, odonatologists have reconfirmed the presence of the elusive dragonfly species, Crocothemis erythraea, in the high-elevation regions of the southern Western Ghats.

About Crocothemis erythraea:

  • It is a species of dragonfly in the family Libellulidae.
  • Its common names include broad scarlet, common scarlet-darter, and scarlet darter.
  • The genus Crocothemis in India includes two known species— servilia and C. erythraea. While C. servilia is common across lowland areas, C. erythraea is known from high-elevation habitats in parts of Europe and Asia, including the Himalayas.
  • The molecular analysis showed that the high-elevation specimens from the Western Ghats match C. erythraea found in the Himalayas.
  • Habitat: The study confirmed that the Western Ghats hosts both the species, C. erythraea, which is restricted to cool, high-elevation habitats (>550 m), while C. servilia is common in lowland habitats (<600 m).
  • The researchers explain that C. erythraea colonised southern India during the Pleistocene Ice Age, when cooler climatic conditions allowed temperate fauna to extend their range southward.
  • As the climate warmed, these populations became stranded in montane locations like the Sholas and grasslands of Munnar and Parambikulam, where they survived in isolation.

What are Prairies?
Recent efforts—including a newly launched database—aim to ensure that the prairies are restored much more comprehensively.

About Prairies:

  • Prairies are flat, temperate grasslands found in North America.
  • Most North American prairies are in locations with a low amount of annual
  • Prairie vegetation is maintained by grazing, fire, drought, and low temperatures.
  • Although grasses dominate, lichens, mosses, forbs, and low- to mid-size shrubs also comprise prairie vegetation.
  • Taller shrubs and trees, mostly willows and poplars, including aspen and cottonwoods, are found in depressions and valleys where there is sufficient moisture and nutrients.
  • Prairie, like other temperate grasslands, is among the most productive and diverse of earth’s terrestrial ecosystems.
  • Grasses, the predominant cover in prairie vegetation, have the following adaptations:
    • Deep or extensive roots.
    • Growing points at or near the soil surface that are tucked in the crown of the plant.
    • Narrow leaves.
    • Small flowers in dense heads that are pollinated by wind.
    • Tough stems and leaves hardened with silica phytoliths (plant stones).
    • Strategies to optimize photosynthesis without losing moisture.
  • Wildlife species living in prairies have adapted to a semi-arid, windy, open environment.
  • Species found here include elk, deer, coyote, bobcat, Badgers, jackrabbits, ground squirrels, pocket gophers, etc
  • Similar temperate grasslands in South America are called Pampas, while in Africa they are described as velds and in Asia are known as steppes.

    • Kohima and other top-ranked cities were associated with stronger gender equity, civic participation, policing, and women-friendly infrastructure.
    • At the other end of the spectrum, cities like Patna and Jaipur fared poorly due to weak institutional responsiveness, patriarchal norms, and gaps in urban infrastructure.
    • Overall, six in ten women surveyed felt “safe” in their city, but 40% still considered themselves “not so safe” or “unsafe”.
    • Prevalence of harassment remains high, with 7% women reporting at least one incident of harassment in public spaces in 2024.
    • The highest risk group is women under 24 years of age (14% reported harassment).
    • Verbal harassment was most common (58%), with physical, psychological, economic, and sexual harassment reported less frequently.

    • In terms of response, 28% of women confronted harassers, 25% left the scene, 21% sought safety in crowds, and 20% reported to authorities.
    • The study revealed sharp drops in perceptions of safety at night, particularly in public transport and recreational spaces.
    • While 86% of women felt safe in educational institutions during daylight hours, safety perceptions fall sharply at night or off-campus.
    • The report shows low levels of faith in the redressal mechanism.
      • Only one in three victims of harassment filed a formal complaint.
      • Only one in four women expressed confidence that authorities would take effective action on their safety complaints.
      • A concerning 53% were unaware whether their workplaces had a Prevention of Sexual Harassment (POSH) policy in place.
