The highly anticipated debut launch of Blue Origin’s New Glenn rocket has been scheduled for January 10, 2025. The heavy-lift rocket, designed for both commercial and government missions, will take off from Florida’s Cape Canaveral Space Force Station. A launch window of three hours, beginning at 1 a.m. EST, has been announced. The rocket’s inaugural flight marks a significant milestone for Blue Origin as the company aims to validate its capabilities and establish itself as a major player in the space industry.

New Glenn’s Mission and Capabilities

According to Blue Origin, as reported by space.com, the New Glenn rocket is a reusable, 320-foot-tall launch vehicle capable of carrying 50 tons (45 metric tons) to low Earth orbit (LEO). The NG-1 mission will test the company’s Blue Ring spacecraft platform, which is designed to support a variety of orbital payloads. This demonstration will include assessments of communication systems, in-space telemetry, and ground-based tracking capabilities. The payload will remain aboard the rocket’s second stage for a six-hour mission, as stated by Blue Origin.

Booster Recovery and Future Goals

The mission will also attempt a recovery of the rocket’s first stage booster, which will land on a ship stationed in the Atlantic Ocean, as per reports from space.com. The company’s senior vice president, Jarrett Jones, emphasised the importance of the flight, stating that rigorous preparations had been undertaken but that true insights could only be gained through actual launch experiences.

NG-1 is a critical step toward securing certification for U.S. national security missions. A successful outcome would bring Blue Origin closer to fulfilling these high-stakes contracts, further solidifying its position in the competitive aerospace sector.

This launch will serve as a proving ground for the New Glenn system, with valuable data expected to inform future missions and technology advancements.

New research has revealed that spiders use specialised hairs on their legs to detect airborne scents, offering fresh insights into the sensory abilities of these arachnids. This discovery has resolved a long-standing question about how spiders, which lack antennae like insects, can identify odours such as pheromones. Male spiders were observed using olfactory hairs, known as wall-pore sensilla, to sense sex pheromones emitted by females. This mechanism underscores their ability to locate potential mates through chemical signals.

Olfactory Sensilla Identified

According to a study, published in the Proceedings of the National Academy of Sciences, the wall-pore sensilla were found on the upper legs of adult male wasp spiders (Argiope bruennichi). These microscopic structures are believed to be critical for detecting pheromones. High-resolution scanning electron microscopy revealed thousands of these sensilla, which were absent in females and juvenile males. This specific distribution supports their role in mate detection. Researchers emphasised to phys.org that these findings have mapped and identified the elusive sensilla, previously thought to be absent in spiders.

Response to Pheromones

Experiments demonstrated the sensitivity of these sensilla to pheromone compounds. Tiny amounts of the substance, such as 20 nanograms, elicited significant neuronal responses. The experiments involved exposing the sensilla to pheromone puffs, and responses were observed consistently across various leg pairs. The researchers concluded that spiders’ olfactory systems rival the sensitivity seen in insects, highlighting their advanced chemical detection capabilities.

Broader Implications

The study explored 19 other spider species and confirmed the presence of wall-pore sensilla in most male spiders, suggesting that this trait evolved multiple times. However, it was noted that some primitive species lack these structures. Future research is expected to investigate how female spiders detect smells, the types of chemicals relevant to their behaviours, and the evolutionary aspects of olfaction in spiders.

This breakthrough provides a foundation for understanding the sophisticated sensory mechanisms that govern spider behaviour.

Exposure to per- and polyfluoroalkyl substances (PFAS), often termed “forever chemicals,” is raising concerns over its impact on wildlife health. Recent research has uncovered significant health problems in freshwater turtles in Australia exposed to PFAS. These issues are not limited to adult turtles but extend to their hatchlings. PFAS, widely known for their persistence in the environment, have been found accumulating in the organs of these reptiles, potentially impacting their long-term survival and reproduction.

Study Reveals PFAS Impacts on Australian Turtles

According to a study published in Science of the Total Environment, researchers, led by David Beale, an environmental biochemist at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), examined freshwater turtles (Emydura macquarii) from three locations in Queensland. These sites varied in PFAS contamination levels, with some showing high concentrations and others barely detectable. The study found that PFAS exposure disrupted metabolic functions in turtles and led to bioaccumulation in vital organs, including the ovaries, liver, kidneys, and heart.

In statements provided to Science News, Beale explained that hatchlings from lab-incubated eggs, derived from PFAS-exposed turtles, showed deformities such as scale abnormalities. He noted that contamination was transferred to offspring via fats and nutrients, raising alarms over generational health impacts.

Concerns Over Declining Juvenile Populations

Reports indicate that juveniles are missing in PFAS-contaminated sites. Beale suggested this could be linked to deformities making them vulnerable to predators or early mortality due to health issues. Differences in egg size and number were also observed, though direct connections to PFAS remain unconfirmed.

Experts Call for Urgent Action

Jean-Luc Cartron, a biologist at the University of New Mexico, expressed concern in his statement to Science News over these findings, emphasising the urgency to address ecological toxicity. He warned that delays in action could result in the loss of entire generations of wildlife.

The research team plans to expand studies to other species and regions, including crocodiles, frogs, and cane toads, to better understand the widespread impact of PFAS on wildlife.
