Plague deadly even before farming's rise

Scientists have uncovered evidence of plague outbreaks among hunter-gatherers near Lake Baikal in Siberia dating back 5,500 years. This discovery challenges the long-held belief that the plague only became a major threat after humans began living in dense, crowded farming communities. The team analyzed ancient DNA, estimating an infection rate of 39%. Interestingly, the ancient plague strains lacked the specific genes needed for flea-borne transmission, suggesting that the disease spread directly from person to person during this prehistoric period, indicating a different transmission mechanism than later outbreaks.

  • Evidence suggests plague outbreaks occurred among hunter-gatherers 5,500 years ago in Siberia.
  • This challenges the traditional view that plague became a major threat only with dense farming communities.
  • Ancient DNA analysis revealed an estimated infection rate of 39% in the prehistoric population.

New seismic hazard spotted in Japan's 2011 quake

Scientists have identified a new seismic hazard following the 2011 Japan earthquake. Fifteen minutes after the main shock, the ground across Japan shifted eastward by up to 6 mm. Using satellite data, researchers discovered this movement was triggered by ScS waves. These seismic waves travel down from the earthquake source, bounce off the planet's core, and return to the surface, hitting Japan's tectonic plate boundaries almost simultaneously. This finding adds a new dimension to understanding earthquake impacts and hazards.

  • A new seismic hazard was identified in Japan following the 2011 earthquake.
  • Ground across Japan shifted eastward by up to 6 mm, 15 minutes after the main shock.

Microsoft introduces pay-as-you-go model for AI agents

Microsoft has introduced a pay-as-you-go model for its AI agents, shifting from traditional fixed software subscriptions to usage-based pricing. This move aligns AI services with the economics of cloud computing, where customers pay for resources as they consume them. The company aims to address the mismatch between highly variable AI usage among employees and flat monthly fees, allowing customers to experiment without large commitments. While offering flexibility, this model could also lead to unpredictable costs, a challenge faced by cloud computing users. Microsoft's experience with Azure's metered consumption model positions it well for this transition.

  • Microsoft is shifting its AI agent billing from fixed subscriptions to a pay-as-you-go model.

IIT-Delhi study finds human activity drives India's 'wild' weather

A new study by IIT-Delhi and KSMDB College Kollam, published in Environmental Research Letters, provides dispositive evidence that human activity is the primary driver of India's increasingly concentrated rainfall and violent floods. Researchers used a 'fingerprinting' technique on rainfall data from 1905 to 2014 to distinguish human influence from natural variations. The study found that greenhouse gas forcing is a dominant driver of extreme precipitation in India's core monsoon zone, particularly West Central India. It also warns that as air pollution reduces, the 'unmasked' full force of greenhouse gas warming could lead to a surge in extreme rainfall events.

  • Human activity, specifically greenhouse gas forcing, is identified as the primary driver of extreme rainfall in India.
  • The 'fingerprinting' technique helped differentiate human-induced changes from natural weather cycles like El Niño.
  • A contest between warming greenhouse gases and cooling aerosols influences rainfall patterns, especially in West Central India.

India Faces American Unilateralism as US-India Ties Become Taxing

The article argues that India is experiencing American unilateralism under the "America First" policy, where the US demands subordination without commensurate benefits. Historically, countries partnered with the US for security, market access, and technology in exchange for strategic autonomy. However, the Trump administration's approach, characterized by extended export controls on AI technologies and disregard for Indian concerns in the Iran conflict, reveals a shift towards dominance without hegemony. This bipartisan American consensus, where sheer power takes center stage, makes US partnerships costly to maintain and leave, urging India to recognize strategic autonomy as elementary realism.

  • India is increasingly facing American unilateralism under the "America First" policy, which prioritizes US dominance without reciprocal benefits.
  • The traditional bargain of strategic autonomy for security and economic advantages from the US is eroding.
  • US actions, such as export controls on AI technologies and disregard for Indian concerns in the Iran conflict, exemplify this unilateral approach.

First global map reveals vast underground network of arbuscular mycorrhizal (AM) fungi

A new study published in Science has unveiled the first global map of the Earth's vast underground network of arbuscular mycorrhizal (AM) fungi. This network, crucial for plant life for millions of years, spans an estimated 110 quadrillion km and weighs around 300 million tonnes of carbon. Forming symbiotic relationships with 70% of plant species, AM fungi sequester approximately 4 billion tonnes of CO2-equivalent annually, about 11% of human-related carbon emissions. The study also identified biodiversity hotspots, such as grasslands in South Sudan, the Tibetan plateau, and India's Banni grasslands, which house 40% of the world's AM fungal networks. However, these vital ecosystems are at extreme risk due to conversion to croplands, which significantly reduces fungal density.

  • The first global map of arbuscular mycorrhizal (AM) fungi reveals a vast underground network crucial for plant life.
  • This network spans 110 quadrillion km and sequesters about 300 million tonnes of carbon.
  • AM fungi form symbiotic relationships with 70% of plant species, sequestering 4 billion tonnes of CO2-equivalent annually.
