NASA's Deep Space Optical Communications (DSOC) technology, demonstrated aboard the Psyche spacecraft, has achieved a groundbreaking milestone by successfully transmitting engineering data over 140 million miles using optical communication. Although Psyche primarily uses radio frequency for data transmission, this feat showcases the potential of optical communication for future missions, including sending humans to Mars.

A new model could explain the cosmic glitch at the edge of the expanding universe, where gravity weakens by about a per cent, according to new research. The widely accepted model of gravity comes from Einstein's theory of general relativity, which has been confirmed through multiple tests and experiments. While the theory has been essential for heorising the Big Bang to photographing black holes, scientists encounter inconsistencies in its predictions when trying to understand gravity on a cosm

Astronomer Frederick Walter suggests gamma-ray bursts could have exterminated extraterrestrial civilizations, potentially explaining the lack of contact with alien life. Despite the threat, Earth's chances of being hit are low due to the rare, directed nature of GRBs.

A recent study has shed light on the origin of the near-Earth asteroid known as Kamooalewa, revealing that it likely originated from the Giordano Bruno crater on the moon's far side. This discovery marks the first time astronomers have traced a potentially hazardous asteroid back to a specific lunar crater, offering new perspectives on the dynamics between Earth and its celestial neighbor.

IIT Madras researchers have identified the Indian Ocean and the Bay of Bengal as potential storage sinks for huge amount of carbon dioxide (CO2) that can be stored there permanently in the form of liquid pools or solid hydrates beyond a certain depth without harming the marine ecology. Some European countries are working on CO2 storage in North Sea.

According to a recent report by the Indian Space Research Organisation (ISRO), the Chandrayaan-3 moon mission of India encountered a four-second delay during launch. This delay was implemented as a precautionary measure to mitigate potential collisions with debris objects and satellites. The chairperson of Isro presented the Indian Space Situational Assessment Report (ISSAR) for 2023 on April 2.

Ahead of the monsoon season, the Union Health ministry announced on Monday its vigilant monitoring of seasonal influenza across different States/Union Territories. This surveillance is conducted in real-time through the Integrated Disease Surveillance Programme (IDSP) network. As of now, there has been no abnormal, alarming rise in cases of seasonal flu in any part of the country, the Union Health Ministry said.

In a long-standing debate, experts discuss varied depression sub-types and genetic influences on stress reactions, challenging the reactive vs endogenous classification. Genetic risk impacts environment sensitivity, potentially affecting stress management strategies.

South and Southeast Asia braced for more extreme heat on Sunday as authorities across the region issued health warnings and residents fled to parks and air-conditioned malls for relief. The hot weather persisted on Sunday, with many flocking to air-conditioned shopping malls and swimming pools for relief.

Over 500 individuals have been moved to safety as 58 homes were obliterated by land subsidence in Ramban district, Jammu and Kashmir. Officials confirm ongoing damage evaluation in Pernote village over the last three days. This aims for swift compensation disbursement to impacted families under State Disaster Response Force guidelines.

Climate change threatens biodiversity decline globally by mid-century, as land-use and climate changes lead to 2-11% biodiversity loss. Conservation, restoration, and natural solutions are crucial for safeguarding ecosystems.

A drought that pushed millions of people into hunger across southern Africa has been driven mostly by the El Nino weather pattern -- not climate change, scientists said on Thursday. Earlier this month, aid agency Oxfam said more than 20 million people faced hunger and malnutrition across southern Africa because of the drought.

Nature study predicts $38 trillion annual losses by 2050 from climate change. Global income to drop 19% by 2050 despite CO2 cuts. Urgent emission reductions needed to avert further economic losses.

BJP and Congress manifestos focus on climate change, lacking specific steps. Experts criticize symbolic promises and contradictory government approaches. Environmental issues need more priority in political discourse amid pressing concerns like air pollution and climate crisis.
