The rise in pandemics has been attributed to disruptions caused by human activities to the planet's ecosystems. Infectious diseases, which have historically resulted in significant loss of life, are appearing more frequently. This resurgence has raised concerns among experts about the factors driving this trend. Modern advancements in science, including vaccinations and antibiotics, initially seemed to have controlled these outbreaks. Yet, the occurrence of diseases such as HIV/AIDS, SARS, and COVID-19 highlights the ongoing challenges.
Ecosystem Disruption and Its Role
According to a study published by researchers from the University of Adelaide, the disruption of ecosystems is central to the emergence of pandemics. Healthy ecosystems regulate diseases by maintaining natural balances, including predator-prey dynamics and vegetation growth. However, activities such as deforestation, climate change, and biodiversity loss have altered these balances, enabling pathogens to spread more easily. For instance, changes in climate have allowed disease-carrying mosquitoes to expand their range into previously temperate regions.
The Impact of Biodiversity Loss
Reports have indicated that biodiversity loss has created opportunities for pathogens to move from wildlife to humans. The case of vampire bats in South America is often cited, where deforestation and agricultural expansion provided new feeding grounds, leading to the spread of rabies. Similarly, the HIV virus emerged through the hunting of apes for food, eventually spreading globally. These examples underscore the link between human activity and the rise of zoonotic diseases.
The Importance of Planetary Health
Experts advocate for a "planetary health" approach, emphasising the interdependence of human health and the natural environment. This strategy aims to address fundamental drivers like climate change while also tackling immediate causes such as wildlife-human interactions. Educational institutions are increasingly integrating planetary health into their curricula to equip future leaders with tools to mitigate pandemic risks effectively.
It is widely believed that without addressing the root causes, the likelihood of future pandemics remains significant. Efforts to balance human development with ecological preservation have been suggested as key to safeguarding global health.

NASA's Parker Solar Probe is set to perform its closest flyby of the sun on December 24, 2024, at 6:53 a.m. EST. The spacecraft, which launched in 2018, will approach within 3.8 million miles (6.1 million kilometres) of the solar surface, setting a record for the nearest distance a human-made object has travelled to a star. Travelling at an extraordinary speed of 430,000 mph (692,000 kph), the probe will traverse the sun's corona, collecting data on its high-temperature environment.
Mission Details and Flyby Preparations
The Parker Solar Probe, managed by NASA and designed at the Johns Hopkins Applied Physics Laboratory (JHUAPL), has completed 21 previous solar encounters and seven flybys of Venus, as per a report by Parker Solar Space. The upcoming event marks the 22nd solar approach in its mission to deepen the understanding of the sun's outer atmosphere. According to Nick Pinkine, mission operations manager at JHUAPL, the probe will provide unprecedented data from regions no spacecraft has explored before.
As part of its preparations, the probe sent a final transmission to Earth on December 20, signalling all systems are functioning normally, according to reports. Contact with the spacecraft will remain offline until December 27, when it is expected to send a health status update. Comprehensive science data, including telemetry, will begin to arrive in January 2025, as per reports.
Engineering to Withstand Extreme Temperatures
During the flyby, the spacecraft will endure temperatures reaching 1,800 degrees Fahrenheit (980 degrees Celsius). Its advanced heat shield, constructed from carbon foam, ensures the probe's instruments remain at near room temperature while withstanding up to 1,377 degrees Celsius.
Future of the Mission
As per reports, two additional close solar flybys are planned for March 22 and June 19, 2025. Decisions regarding the spacecraft's trajectory and continued operations are expected after the primary mission concludes. The Parker Solar Probe's findings aim to address critical questions about the sun's behaviour, contributing to the broader understanding of solar phenomena.

The innermost planet of the TRAPPIST-1 system, TRAPPIST-1b, may possess a carbon dioxide-rich atmosphere, according to research published in Nature Astronomy on December 16. The TRAPPIST-1 system, which lies 40 light-years from Earth and includes seven Earth-sized exoplanets, has intrigued astronomers since its discovery in 2017. Earlier studies suggested that these planets lacked atmospheres due to intense stellar radiation. However, recent data from the James Webb Space Telescope (JWST) raises the possibility of a hazy, carbon dioxide-heavy atmosphere on TRAPPIST-1b.
Findings on Atmospheric Composition
As per reports, the study highlights new measurements taken at 12.8 micrometres, showing evidence of a reflective haze in TRAPPIST-1b's upper atmosphere. Researchers believe this haze may cause upper layers to emit rather than absorb radiation, challenging previous assumptions. Speaking to KU Leuven News, Leen Decin, co-author of the study and researcher at KU Leuven in Belgium, noted, that the two data points for TRAPPIST-1b allows them to explore various scenarios for its atmosphere, whether it exists or not.
Volcanism and Surface Conditions
The research also indicates elevated surface temperatures, suggesting potential volcanic activity. Similar dynamics have been observed on Saturn's moon Titan. According to Michiel Min from the SRON Netherlands Institute for Space Research, who contributed to the study, in a statement, the atmospheric chemistry of TRAPPIST-1b is expected to be unlike anything seen on Titan or in the solar system.
Ongoing Studies
The team aims to examine heat distribution across the planet's surface to determine whether an atmosphere is present. Michaël Gillon, an astronomer at the University of Liège who led the discovery of the TRAPPIST-1 system, explained to Nature Astronomy that an atmosphere would facilitate heat redistribution from the day to night side of the planet. Without it, heat transfer would be minimal.
These findings may reshape understanding of atmospheres around exoplanets near red dwarf stars, according to experts.

A study published in Physical Review Letters explores a new approach to detecting the gravitational wave memory effect, a phenomenon predicted by Einstein's general relativity. This effect refers to the permanent alteration in the distance between cosmic objects caused by a passing gravitational wave. Scientists suggest that existing gravitational wave observatories could capture this elusive signature, specifically from core-collapse supernovae (CCSN), which occur when massive stars over ten times the Sun's mass collapse and explode.
Core-collapse supernovae generate gravitational waves with unique characteristics due to their changing quadrupole moments during collapse. According to reports, while the amplitude of these waves is lower compared to signals from black hole or neutron star mergers, they provide critical insights into stellar interiors. Unlike electromagnetic signals, which originate from a supernova's surface, gravitational waves emerge from deep within, offering a rare glimpse into the dynamics of a collapsing star.
Challenges of Detecting Supernova Gravitational Waves
Detection of gravitational waves from CCSN has proven difficult due to their lower amplitudes, shorter durations, and complex signatures. Reports state that these waves fall below the sensitivity range of current high-frequency detectors such as advanced LIGO. However, the study indicates that low-frequency gravitational waves from CCSN exhibit a "memory" effect. This effect arises from anisotropic neutrino emissions and matter movement during collapse, leaving a non-zero gravitational disturbance.
As per reports, the research team, led by Colter J. Richardson from the University of Tennessee, analysed three-dimensional simulations of non-rotating CCSN with masses up to 25 solar masses using the CHIMERA model. Their findings revealed a distinct ramp-up in gravitational wave signals characteristic of memory with matched filtering techniques, the team concluded that signals from a 25 solar mass supernova could be detected up to 10 kiloparsecs away, a range accessible by existing observatories.
Potential for Future Research
Richardson highlighted, as per sources, the significance of exploring low-frequency gravitational waves and encouraged further investigations using the study's methodology. Future research may focus on common merger events or improvements in detector sensitivity to refine the detection of memory signals.

NASA's retired InSight Mars lander was recently spotted by the Mars Reconnaissance Orbiter (MRO) in an image taken on October 23, 2024, using its High-Resolution Imaging Science Experiment (HiRISE) camera. The image shows dust build-up on the lander's solar panels, which now match the reddish-brown colour of the Martian surface. Reports suggest this observation continues to provide insights into the movement of dust and wind patterns on Mars.
InSight's Mission and Retirement
The InSight lander, which touched down in November 2018, was central to detecting Marsquakes and studying the planet's crust, mantle, and core. NASA officially ended the mission in December 2022 after the lander stopped communicating due to excessive dust accumulation on its solar panels. Engineers from NASA's Jet Propulsion Laboratory (JPL) in California continued to monitor the lander for any signs of reactivation, hoping Martian winds might clear its panels. However, as per reports, no signals have been received, and listening operations will conclude by the end of this year.
Tracking Dust Movement
The new HiRISE images were captured to monitor how dust and wind alter the Martian surface over time. Ingrid Daubar, a science team member at Brown University, told sources that the images of InSight's location offer crucial data on how dust accumulates and shifts. This information helps researchers understand the Martian dust cycle and wind dynamics, which are vital for future missions.
Surface Changes and Impact Studies
Dust movement not only impacts solar-powered missions but also helps scientists study surface ageing processes. Blast marks left by InSight's landing thrusters, once dark and prominent in 2018, have faded significantly, indicating dust deposition over time. This phenomenon also aids researchers in estimating the age of craters and surface features, as dust gradually erodes their visibility.
Ongoing Role of Mars Reconnaissance Orbiter
The Mars Reconnaissance Orbiter continues to play a key role in observing Mars' surface changes. It monitors both active missions, such as the Perseverance and Curiosity rovers, and inactive ones, including Spirit, Opportunity, and the Phoenix lander. Managed by JPL for NASA's Science Mission Directorate, the orbiter's HiRISE camera remains a vital tool for long-term studies of the Martian environment.

A long-standing mathematical puzzle known as the "sofa problem," posed in 1966 by Austrian-Canadian mathematician Leo Moser, may have finally been solved. The problem involves determining the maximum area of a single, planar shape that can navigate a right-angled corner in a hallway of unit width. This question, despite its seemingly simple premise, has confounded mathematicians for over half a century.
Jineon Baek, a postdoctoral researcher in mathematics at Yonsei University in South Korea, has reportedly proposed a solution. According to a study shared on the preprint website ArXiv on December 2, Baek demonstrated that the maximum area of the hypothetical sofa is 2.2195 units. This value refines the previously established range of 2.2195 to 2.37 units. While the proof awaits peer review, experts are expected to verify its accuracy.
Origins and Prior Developments
The problem was initially conceptualised by Leo Moser and progress was made in 1992 when Joseph Gerver, an emeritus professor at Rutgers University, proposed a U-shaped solution comprising 18 curves. Gerver's calculations suggested the lower bound of 2.2195 units for the sofa's area. Disputes persisted over whether a larger sofa could exist, with a 2018 computer-assisted analysis suggesting an upper bound of 2.37 units.
Key Insights from Baek's Proof
Baek's findings reportedly confirm that Gerver's solution represents the optimal configuration. By meticulously analyzing the geometry and movement of the shape, Baek demonstrated that the U-shaped design could achieve the maximum possible area for navigating the corner.
While the study has yet to be published in a peer-reviewed journal, the mathematical community has shown significant interest. Images of the "Gerver sofa" circulated on social media following Baek's announcement, sparking discussions about the implications of this long-awaited resolution.
This breakthrough is anticipated to close the chapter on one of mathematics' enduring conundrums, pending independent verification of Baek's work.

Research indicates that Earth's solid inner core, a metal sphere encased within the molten outer core, could be undergoing changes in both rotation and surface structure. Studies involving seismic waves from earthquakes have revealed that the core's rotation may have slowed, paused or even reversed relative to Earth's surface approximately 15 years ago. New findings presented by John Vidale, a geophysicist at the University of Southern California, during a meeting of the American Geophysical Union suggest that additional changes to the inner core's surface could also be occurring.
Earthquake Waves Reveal Inner Core Dynamics
Insights into the inner core rely on seismic waves generated by earthquakes, as no instrument can directly access Earth's core. According to reports, geophysicists often examine seismic waves originating from the South Sandwich Islands near Antarctica. These waves traverse the Earth, passing through its layers and arriving at recording stations such as those in Alaska. Waveform discrepancies between similar earthquakes occurring at different times indicate changes within the inner core.
Surface Changes and Deformation Hypotheses
Reportedly, Vidale and his team analysed seismic data from around 200 earthquake pairs recorded between 1991 and 2024. Discrepancies in waveforms were observed in recordings from Yellowknife, Canada but not from Fairbanks, Alaska. Vidale attributed these differences to possible deformation of the inner core's outer surface. According to reports, the entire core might be subtly reshaping or localised regions could be swelling or contracting. These changes might be influenced by gravitational interactions with the mantle or material flow within the outer core.
Diverse Perspectives on Core Behavior
The interpretations remain debated. Lianxing Wen, a geophysicist from Stony Brook University, has suggested in a statement that surface changes alone, without rotational differences, might explain these observations. Meanwhile, Xiaodong Song of Peking University emphasised in his statement that both rotational and surface changes could be contributing factors.
Current findings remain limited in their implications for Earth's surface, as stated in reports. Until further research clarifies the processes, the potential impact remains uncertain.

New research has indicated a strong connection between warm, sunny days on Mars and the occurrence of dust storms, with nearly 78 percent of storms preceded by increased solar heating, according to a study presented at the annual meeting of the American Geophysical Union in Washington, D.C. The study, led by Heshani Pieris and Paul Hayne of the University of Colorado, Boulder, analysed data from NASA's Mars Reconnaissance Orbiter, revealing patterns that could help predict these atmospheric phenomena.
Insights into Dust Storm Patterns
The researchers investigated data spanning eight Martian years—approximately 15 Earth years—collected by the Mars Climate Sounder instrument. Observations focused on two types of dust storms, categorised as "A" and "C" storms, which primarily originate in the planet's northern hemisphere and travel through Acidalia Planitia and Utopia Planitia. The study found a direct correlation between prolonged surface heating and the emergence of these storms.
In a statement, Pieris highlighted the significant impact dust storms have on Mars missions, noting their tendency to coat solar panels with fine particles, which can disrupt operations. This was exemplified by NASA's Opportunity rover, which was rendered inoperable during a global dust storm.
Potential for Forecasting Dust Storms
Pieris and Hayne's research suggests the possibility of predicting Martian dust storms based on patterns of surface heating. An algorithm developed during the study has shown a 64% confidence level in forecasting "A" and "C" storms, offering a potential tool for managing the risks posed to future crewed missions.
While the study marks progress, as per reports, Hayne pointed out that fundamental questions about dust storm formation remain unanswered, including the factors that allow localised storms to grow into global events. Data from NASA's deactivated Mars Global Surveyor supports the findings, showing that imbalances in solar energy absorption during warmer periods can fuel storm activity.

The origins of the universe's largest galaxies, long a mystery to astronomers, may have been revealed by a new study published in Nature on December 4. Researchers have suggested that cosmic collisions between galaxies billions of years ago could have created the most massive star systems. These galaxies, unlike the Milky Way's flat spiral shape, exhibit a spherical, bulging structure. According to the findings, these collisions likely took place when the universe was just 1 to 5 billion years old and were marked by intense bursts of star formation.
Key Observations Made Using ALMA
Observations made by the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile played a crucial role in this research. A team led by Qing-Hua Tan of the Purple Mountain Observatory examined the light distribution from over 100 distant galaxies. These galaxies, identified in archival data from the A3COSMOS and A3GOODSS projects, were studied for their extreme star-forming activity.
Tan stated to Nature that direct evidence has been found indicating that these spheroidal galaxies formed through episodes of intense star formation at their cores. The study demonstrates how gas, drawn toward the centres of colliding galaxies, facilitated the creation of stars at rates significantly exceeding those of the Milky Way.
Insights into Early Universe Evolution
University of Southampton researcher Anna Puglisi, part of the team, explained to Nature that these processes occurred 8 to 12 billion years ago, during a period when the universe experienced heightened activity. The study marks a significant step toward understanding early galactic evolution.
As per reports, the researchers plan to integrate their findings with data from the James Webb Space Telescope and the Euclid satellite to map star populations within these galaxies. According to Puglisi, in a statement, this combined analysis could provide a more comprehensive understanding of how galaxies formed and evolved in the universe's early stages.
