Women in leadership are often told to 'Lean In', designed to be motivational messaging demonstrating that they are more confident, strategic and resilient to setback. However, new research indicates that such 'lean in' messaging can hinder women's motivation to protest gender equality. Read more ›

Researchers developed a computer vision framework for posture estimation and identity tracking which they can use in indoor environments as well as in the wild. They have thus taken an important step towards markerless tracking of animals in the wild using computer vision and machine learning. Read more ›

Plant hydraulics drive the biological process that moves fluids from roots to plant stems and leaves, creating streaming electric potential, or voltage, in the process. A study closely examined the differences in voltage caused by the concentrations of ions, types of ions, and pH of the fluid plants transport, tying the voltage changes to the plant's circadian rhythm that causes adjustments day and night. According to the authors, this consistent,... Read more ›

The African turquoise killifish lives in ephemeral ponds in Zimbabwe and Mozambique. To survive the annual dry season, the fish's embryos enter a state of extreme suspended animation or 'diapause' for approximately 8 months. Now, researchers have uncovered the mechanisms that enabled the killifish to evolve this extreme survival state. Read more ›

As the planet has warmed, scientists have long been concerned about the potential for harmful greenhouse gasses to seep out of thawing Arctic permafrost. Recent estimates suggest that by 2100 the amount of carbon dioxide and methane released from these perpetually frozen lands could be on par with emissions from large industrial countries. However, new research led by a team of microbiome scientists suggests those estimates might be too low. Read more ›

Through a study of 1,002 participants, scientists have found that almost half (45.7 per cent) say they intend to use air taxis when they become available, with over one-third (36.2 per cent) planning to do so regularly. According to the findings, the intention to take autonomous air taxis is associated with factors such as trust in the AI technology deployed in air taxis, hedonic motivation (the fun or pleasure derived...

Switching food and drink purchases to very similar but more environmentally friendly alternatives could reduce the greenhouse gas emissions from household groceries by more than a quarter (26%), according to a new study. Read more ›

Maize is one of the world's most widely grown crops and is essential to global food security. But like other plants, its growth and productivity can be limited by the slow activity of Rubisco, the enzyme responsible for carbon assimilation during photosynthesis. Scientists have now demonstrated a promising approach to enhancing Rubisco production, thus improving photosynthesis and overall plant growth. Read more ›

Australian researchers have found evidence of the oldest known platypus and a new species, dubbed 'echidnapus', which has a platypus-like anatomy alongside features that more closely resemble an echidna. Read more ›

Boilers are a major source of greenhouse gas emissions. In a recent study, researchers developed a method to convert CO2 emissions from small boilers into methane, which makes use of an optimized reactor design that evenly distributes the CO2 feed. This, in turn, results in significantly lower temperature increments and a boost in methane production. This innovative technique could pave the way for reducing greenhouse gas emissions. Read more ›

By analyzing the dynamics of 12 back-to-back explosions that happened in 2018, researchers describe a new type of volcanic eruption mechanism. The explosions were driven by sudden pressure increases as the ground collapsed, which blasted plumes of rock fragments and hot gas into the air, much like a classic stomp-rocket toy. Read more ›

While most organisms have biological clocks synchronized with the day-night cycle (circadian rhythms), marine animals in tidal areas have also developed circatidal rhythms to align with the tidal cycle. Comparing the activity and genetic expression of snails from tidal and non-tidal areas, researchers demonstrate that circatidal rhythms develop as snails adapt to tidal environments. These findings highlight the flexibility of biological clocks, enabling organisms to adjust their rhythms according to... Read more ›

Entomologists have solved the 250-year-old origin puzzle of the most prevalent indoor urban pest insect on the planet: the German cockroach. The team's research findings, representing the genomic analyses of over 280 specimens from 17 countries and six continents, show that this species evolved some 2,100 years ago from an outdoor-living species in Asia.
