A recent study has investigated teleparallel gravity and its potential to resolve tension surrounding the expansion of the universe in a way that general relativity can’t.
Researchers discovered four mini-Neptunes with volatile-rich compositions around red dwarfs, using both space and ground-based telescopes. Researchers discovered mini-Neptunes[1] around four red dwarfs[2], which are named TOI-782, TOI-1448, TOI-2120, and TOI-2406, using observations from a glob.

A team from Nagoya University invented a heat-switch device for lunar rovers to withstand the Moon’s extreme temperatures. The technology optimizes thermal control, alternating between cooling and insulating, facilitating longer missions with less energy.
Astronauts navigating the moon’s terrain in a vehicle contend with not only the perils of zero gravity and potential crater falls, but also drastic temperature swings. The moon’s climate ranges from searing highs of 127°C (260°F) to bone-chilling lows of −173°C (−280°F).
Team from Nagoya University in Japan developed a heat-switch device designed to enhance the durability of lunar rovers. Their collaborative research with the Japan Aerospace Exploration Agency was featured in the journal Applied Thermal Engineering.
Scientists found that water in our solar system is likely billions of years older than the sun by studying the protostar V883 Orion, linking water from the interstellar medium to our solar system.
This research suggests that water in our solar system was formed long before the sun, planets, and comets, indicating that planetary systems.
A bioresorbable, wireless hydrogel (metagel) sensor, encompassing both biodegradable and stimulus-responsive hydrogels for ultrasonic monitoring of intracranial signals, was implanted into intracranial space with a puncture needle and deformed in response to physiological environmental changes.
NASA has developed a gravity-defying drive that achieves 1G thrust without propellant, potentially revolutionizing space propulsion technology Questions to inspire discussion What is the NASA gravity-defying drive? —The NASA gravity-defying drive is a propulsion system that achieves 1G thrust without the need for propellant, potentially revolutionizing space propulsion technology.
Recent years have seen increasing public attention and indeed concern regarding Unidentified Anomalous Phenomena (UAP). Hypotheses for such phenomena tend to fall into two classes: a conventional terrestrial explanation (e.g., human-made technology), or an extraterrestrial explanation (i.e., advanced civilizations from elsewhere in the cosmos). However, there is also a third minority class of hypothesis: an unconventional terrestrial explanation, outside the prevailing consensus view of the universe. This is the ultraterrestrial hypothesis, which includes as a subset the “cryptoterrestrial” hypothesis, namely the notion that UAP may reflect activities of intelligent beings concealed in stealth here on Earth (e.g., underground), and/or its near environs (e.g., the moon), and/or even “walking among us” (e.g., passing as humans). Although this idea is likely to be regarded sceptically by most scientists, such is the nature of some UAP that we argue this possibility should not be summarily dismissed, and instead deserves genuine consideration in a spirit of epistemic humility and openness.
