As humankind imagines living off-planet -- on the moon, Mars and beyond -- the question of how to sustain life revolves around the physical necessities of oxygen, food and water. We know there is water on the moon, but how do we find it? Researchers may help bring science fiction to reality by providing a divining rod to guide future space missions.
Schizophrenia is a serious mental disorder that affects around 1% of the world's population. Researchers have identified a deficit in contrast perception in people with schizophrenia. According to a review of more than 600 studies, these patients have an impaired ability to see differences in light intensity between adjacent areas, which allows us to identify shapes, textures and details in the en
A new study finds that prompts do a good job of getting drivers to engage with their environment and take over control of the vehicle when necessary while using partially automated driving systems -- with one exception. If drivers are deeply distracted, these system-generated prompts have little or no effect.
Mites who hitchhike on the beaks of hummingbirds use a surprising method to help them on their journey: electricity. These hummingbird flower mites feed on nectar and live within specific flowers for their species. When it is time to seek out a new flower, they hitch a ride via hummingbirds, but for years researchers have not been sure exactly how these tiny, crawling arachnids quickly disembark a
A team of stem cell scientists have successfully used embryonic stem cell engineering to create a bi-paternal mouse -- a mouse with two male parents -- that lived until adulthood. Their results describe how targeting a particular set of genes involved in reproduction allowed the researchers to overcome previously insurmountable challenges in unisexual reproduction in mammals.
The fact that the cold, dry Mars of today had flowing rivers and lakes several billion years ago has puzzled scientists for decades. Now, researchers think they have a good explanation for a warmer, wetter ancient Mars. Building on prior theories describing the Mars of yore as a hot again, cold again place, a team has determined the chemical mechanisms by which ancient Mars was able to sustain eno

Mitochondria organelles came from primordial bacterial endosymbionts and still preserve distinct genes for important functions like making ATP. To speed the emerging therapeutic research into the transfer of mitochondria between cells, 31 researchers have developed consensus recommendations for common terminology that describes mitochondria transfer and transplantation.
Archaeologists have uncovered evidence that a house in England is the site of a lost residence of Harold, the last Anglo-Saxon King of England, and shown in the Bayeux Tapestry. By reinterpreting previous excavations and conducting new surveys, the team believe they have located a power center belonging to Harold Godwinson, who was killed in the Battle of Hastings in 1066.
Astronomers and engineers have developed a specialized system for their radio telescope to rapidly detect mysterious fast radio bursts and other space phenomena.
A person's lifetime risk for cancer may begin before they are even born, reports a paradigm-shifting study. The findings identified two distinct epigenetic states that arise during development and are linked to cancer risk. One of these states is associated with a lower lifetime risk while the other is associated with a higher lifetime risk.
Physicists have discovered a sophisticated, previously unknown set of 'modes' within the human ear that put important constraints on how the ear amplifies faint sounds, tolerates noisy blasts, and discerns a stunning range of sound frequencies in between. By applying existing mathematical models to a generic mock-up of a cochlea -- a spiral-shaped organ in the inner ear -- the researchers revealed
An interdisciplinary team of researchers has projected that if the rate of global CO2 emissions continues to increase and reaches a high emission scenario, sea levels would as a result very likely rise between 0.5 and 1.9 meters by 2100. The high end of this projection's range is 90 centimeters higher than the latest United Nations' global projection of 0.6 to 1.0 meters.
A research team developed a new experimental game to explore whether people avoid witnessing selfish behavior to evade punishing others or simply to avoid confronting unfairness. The study found that avoidance is driven by both the desire to not acknowledge inequality and the wish to prevent confrontation, suggesting that altruistic punishment may be less common in real-life situations than previo
The dwarf planet is a bizarre, cryovolcanic world. However, the organic deposits discovered on its surface so far are unlikely to originate from its interior. The organic material found in a few areas on the surface of dwarf planet Ceres is probably of exogenic origin. Impacting asteroids from the outer asteroid belt may have brought it with them.
Proteins, the pillars of cellular function, often assemble into 'complexes' to fulfill their functions. A study reveals why this assembly often begins during the very process of protein synthesis or 'birth'. These early interactions involve proteins whose stability depends on their association. They can be compared to a couple in which each partner supports the other. This model paves the way for
Various diseases can be treated by stimulating the vagus nerve in the ear with electrical signals. However, this technique does not always work. A study has now shown: The electrical signals must be synchronized with the body's natural rhythms -- heartbeat and breathing.
Dating key tectonic events in Japan's geological history has long been often challenging due to poor microfossil preservation from intense heat due to metamorphism. Researchers tackled this by using Re--Os isotope geochronology on Besshi-type volcanogenic massive sulfide deposits (Makimine and Shimokawa deposits) associated with sediment-covered mid-ocean ridges. Their findings revealed the timing
Ice nucleating particles as a kind of aerosols have a significant impact on the Arctic climate by promoting the formation of ice clouds at a temperature above -- 38 degrees Celsius. Wildfires in mid-latitudinal areas are a major source of these aerosols. However, a direct observation of wildfire-emitted aerosols facilitating ice cloud formation has never been documented. Now, using field and clima
Lithium-air batteries have the potential to outstrip conventional lithium-ion batteries by storing significantly more energy at the same weight. However, their high-performance values have thus far remained theoretical, and their lifespan remains too short. A team has now proposed addition of a soluble catalyst to the electrolyte. It acts as a redox mediator that facilitates charge transport and c
The world of quantum physics is experiencing a second revolution, which will drive an exponential leap in the progress of computing, the internet, telecommunications, cybersecurity and biomedicine. Quantum technologies are attracting more and more students who want to learn about concepts from the subatomic world -- such as quantum entanglement or quantum superposition -- to explore the innovative
An international team of scientists has discovered a way to store and release volatile hydrogen using lignin-based jet fuel that could open new pathways for sustainable energy production. In a new study scientists demonstrated that a type of lignin-based jet fuel they developed can chemically bind hydrogen in a stable liquid form. The research has many potential applications in fuels and transport
Effective management of phosphorus is needed to curb the rise of harmful algal blooms. Few studies have explored how algal biomass, especially blue-green algae, can be used to create materials that remove phosphate from water. Researchers have filled that gap by transforming cyanobacterial biomass into materials that can pull harmful phosphorus out of water. Materials treated in the study removed
Researchers have pioneered an innovative method using helioseismology to measure the solar radiative opacity under extreme conditions. This groundbreaking work not only reveals gaps in our understanding of atomic physics but also confirms recent experimental results, thereby opening new perspectives in astrophysics and nuclear physics.
Scientists have performed laboratory experiments to better understand how Saturn's moon Titan can maintain its unique nitrogen-rich atmosphere. Titan is the second largest moon in our solar system and the only one that has a significant atmosphere.
Basal cell carcinomas, the most common form of skin cancer, occur in chronically sun-exposed areas such as the face. Locally advanced tumors in particular can be difficult to treat surgically. A research team has now investigated the effectiveness of a new type of therapy and achieved promising results: The active substance TVEC led to a reduction in the size of the basal cell carcinoma in all stu
Climate change will likely result in a significant rise in deaths from heat across Europe, substantially surpassing any decrease in cold-related deaths, according to a new modelling study. This trend persists across climate change scenarios and even under high adaptation to heat, reinforcing the need for aggressive mitigation policies.
Using syrup and baking soda, research has demonstrated the formation mechanism of rootless cones, small volcanic landforms commonly found on Earth and Mars. The study clarified, through an experimental approach, that a self-organization process determines the spatial distribution and size of these landforms. This research will enhance our understanding of explosive eruption phenomena caused by the
Japan Sea element plants are generally thought to have evolved from closely related species on the Pacific side. Camellia japonica and Camellia rusticana were also believed to follow this pattern. However, a new study revealed that their origins trace back to the Miocene, when the Japanese archipelago separated from the continent.
