Indian researchers find gut bacteria protein signals fullness to brain

Scientists in India have discovered an ancient bacterial protein in the gut that directly signals the brain when we feel full, revealing a new “sixth sense” regulating appetite. The protein activates neural pathways reducing food intake and also influences mood and mental health. The finding opens avenues for obesity treatments and understanding gut‑brain interactions. Researchers emphasise its potential in designing therapies targeting metabolic disorders. The study was published August 1, 2025, and is being hailed for its cross‑disciplinary impact between microbiology, neuroscience and nutrition science. (Indian Express)

Singapore startup DECOD uses radar to detect sinkholes before disasters

DECOD Science & Technology, founded by Singaporean Zhi Haiyan, has developed radar‑based “road health checkups” to detect subsurface risks such as sinkholes, loose soil or shifting pipelines beneath roads, rail tracks, and runways. The radars scan underground without disruption to traffic, enabling early detection of voids or weak spots that could become hazards. Comparable to medical CT scans, the technology visualises underground anomalies and allows preventative intervention. DECOD’s system promises infrastructure resilience in urban environments prone to subsidence or aging underground networks. (Channel News Asia)

Deep‑sea Livestream Captivates Argentina, Sparks Science Funding Protest

A deep‑sea livestream of South Atlantic marine life—broadcast from a 4,000 m‑depth remotely operated vehicle jointly operated by Argentina’s Conicet and the U.S.-based Schmidt Ocean Institute—has drawn over 1.6 million daily views. Stunning footage of translucent squid, bright starfish and other rarely seen creatures has enthralled the public and inspired imaginative social media commentary. Coming amid sharp austerity under President Javier Milei—which saw the Ministry of Science dissolved and Conicet’s budget cut by 21%—the stream has galvanized scientific pride and protest. Argentine researchers have launched a 48‑hour strike over layoffs and wage losses, positioning the livestream as both an inspiration and a symbol of science’s societal value. (AP)

NASA Officially Cancels Lunar Trailblazer Mission

NASA has formally terminated the Lunar Trailblazer smallsat mission over five months after losing contact shortly after launch. The orbiter was intended to map water content on the Moon by characterizing the form and distribution of lunar water molecules. Its failure marks another setback for NASA’s low-cost planetary mission ambitions. Despite efforts to reestablish communication, engineers were unable to recover the spacecraft, prompting the agency to write off the project. The loss may influence future strategies for small-scale missions aimed at essential planetary science, raising questions about balancing cost-efficiency against mission reliability in lunar exploration.

Meta’s High‑Spending AI Talent Strategy Draws Scrutiny

Meta, under Mark Zuckerberg, is investing tens of billions to build a “personal superintelligence” AI lab by recruiting elite talent, reportedly offering nine‑figure sign‑on bonuses to figures such as ChatGPT co‑creator Shengjia Zhao and mathematician Alexandr Wang. Critics warn that assembling teams of “superstars” may backfire: studies show mixed teams tend to outperform star-only groups due to better collaboration and knowledge sharing. Some internal staff fear displacement or cultural disruption. Effective leadership and integration will be critical if Meta hopes to turn its mega‑scale recruitment strategy into meaningful AI breakthroughs, not just headline‑grabbing hires. (FT)

Shanghai team implants invasive brain‑computer interface in clinical trial

A team at Shanghai’s Huashan Hospital and CAS’ Center for Excellence in Brain Science & Intelligence Technology implanted an invasive brain‑computer interface (BCI) in a patient who lost all four limbs, allowing him to play a racing game using only his mind. The trial began March 25, 2025, and aims next to enable control of robotic arms, robot dogs, and embodied intelligent devices. Researchers say this opens new frontiers in assistive robotics and neuroprosthetics. The device decodes neural signals to restore functional autonomy, potentially transforming quality of life for paralyzed patients. The project is among China’s most advanced BCI efforts and may lead toward clinical deployment. (CAS)

First Female Astronomer Royal Appointed in UK

Planetary scientist Professor Michele Dougherty has become the first female Astronomer Royal in the UK’s 350‑year history. Known for discovering water-vapor plumes on Saturn’s moon Enceladus during the Cassini mission and leading the ESA JUICE mission studying Jupiter’s Ganymede, Dougherty assumes the honorary role created in 1675. She aims to engage the public with astronomy and emphasize its economic and societal relevance. In interviews, she highlighted the role model potential for young girls and cautioned about unstable science funding. She continues her professorship at Imperial College London and holds prominent positions in the UK scientific community. (The Guardian)

Automation Revolutionizes Biopharma Protein Purification

Protein purification in biopharmaceutical labs is undergoing a transformation via automation. Collaborative robotics and workflow software now enable more complex purification processes to run with minimal human intervention. While fully automated workflows promise lower costs and faster drug development, many labs must upgrade infrastructures to support them. Current systems still depend on customization and expert oversight, but the shift toward standardized automation platforms is gaining momentum. Industry analysts believe the innovation can accelerate research pipelines and increase reproducibility, though widespread adoption hinges on flexibility, reliability and the ability to integrate into existing lab environments.

Southwest U.S. Drought Expected to Persist Through 2100

A recent climate study projects that the prolonged drought afflicting the southwestern United States is likely to continue well into the late 21st century and potentially beyond. As global warming intensifies, reduced precipitation and increased evaporation may cement arid conditions across the region, impacting water availability, agriculture, and ecosystems. The analysis indicates that even with emissions reductions, warming trends and megadrought risks remain high, posing challenges for resource management. Adaptation strategies—such as water conservation, drought-resistant crop development, and infrastructure upgrades—are urgently needed to mitigate the anticipated long-term impacts on communities and natural systems.

Penguin Guano May Help Stabilize Antarctic Climate

New research reveals that emperor penguin guano contributes ammonia aerosol particles that promote the formation and persistence of low clouds over Antarctica. These clouds reflect solar radiation, reinforcing cooling conditions in the region. The findings suggest that penguin colonies exert an underappreciated role in local climate regulation. Scientists argue that this biogenic aerosol feedback may help buffer warming, though decreasing penguin populations could weaken the effect. The study highlights the nuanced interconnections between wildlife and climate dynamics, emphasizing how ecosystem changes may have cascading weather implications on polar regions. (Ars Technica)

Scientists Urge NASA to Plan Apophis Asteroid Mission

With the near-Earth asteroid Apophis set for a close Earth flyby in 2029, planetary scientists are urging NASA to accelerate planning for a smallsat mission using repurposed spacecraft to study the body. Visiting Apophis before its approach would offer unique opportunities to examine its structure, composition and orbital behavior. The mission concept could be realized quickly and at relatively low cost by adapting existing satellite platforms. Researchers stress that understanding Apophis’s physical characteristics ahead of its flyby could refine hazard assessment and deepen our knowledge of potentially threatening near-Earth objects.
