A team of international researchers used CT scans and biomechanical modelling to understand how Diplodocus fed on tree branches. They found that combing and raking of leaves was a stress-free feeding behaviour for the skull bones and teeth, contradicting previous hypotheses.
The study analyzed the performance of bolted joints in aeronautical structures, finding that low temperatures or low torque levels increase the risk of failure. Researchers developed a numerical model to estimate joint torque based on temperature ranges, which can help reduce aircraft weight and fuel consumption.
Researchers at MIT have devised a new method to detect internal damage in airplane composite materials, allowing for faster inspection. The approach uses a handheld device and heat-sensitive camera to reveal underlying problems.
A study by the Spanish Railways Foundation found that high-speed trains, such as the AVE, consume 29% less energy and produce 31kg less CO2 per passenger compared to traditional trains. The main advantage of high-speed lines is not in reducing fossil fuel consumption, but in attracting passengers who would otherwise travel by air or car.
Researchers in California and South Africa re-designed an aircraft with a bird-inspired shape to improve aerodynamics and reduce fuel consumption. The study showed that a flying wing configuration can generate nearly wing-only levels of lift and drag, potentially making planes more energy efficient.
Historian R.M. Douglas's research challenges the notion that British forces used chemical weapons against Iraqis after World War I, citing faulty evidence and official records that contradict these claims. Despite the lack of evidence, the allegations have persisted as a rallying cry for anti-war critics.
Scientists from the University of Leeds and the Zoological Society of London have found that mosquitoes are regularly hitching a ride on tourist boats and breeding with existing populations.
Interactions between ozone and body oils can lead to the formation of chemical byproducts that worsen nasal irritation, headaches, and other air traveler complaints. The study suggests simple steps like installing ozone-destroying catalysts can help reduce these byproducts in aircraft and buildings.
A new national strategy could utilize small, lightweight jets to reduce congestion at major airports. The simulation predicts that policy changes are necessary to streamline the system, including better coordination among airlines and infrastructure providers.
Researchers have invented an optical on-off switch that can replace electrical wiring on airplanes with fiber optics for controlling elevators, rudders, and other flight-critical elements. This technology also has potential applications on highways as a 'weigh-in-motion' sensor for measuring the weight of fast-moving commercial trucks.
Researchers have developed a rapid testing method, PASD, to diagnose and repair intermittent faults in aircraft wiring harnesses. The technique uses a high-voltage pulse to detect small insulation breaks, allowing technicians to locate and fix faulty wires efficiently.
Researchers found that extending a bee's legs generates stabilizing lift forces, reducing rotational instability and enabling faster flight speeds. By mimicking this design in miniature flying machines, search and rescue missions could potentially benefit from increased speed and agility.
A new theory explains how cracks propagate in brittle materials, shedding light on material failure in nanoscale devices, airplanes, and earthquakes. The research simulates the behavior of atoms under extreme conditions, uncovering the physics behind fractures.
Engineers use new anechoic wind tunnel to study and reduce airframe noise caused by plane wings, flaps, and landing gear. The $400,000 facility helps address increasing noise-related problems with growing air travel worldwide.
Researchers are working on a method to accurately estimate coral reef health from sensors on airplanes and satellites. By analyzing light reflectance from corals, scientists can detect early signs of disease and stress, providing valuable insights into marine ecosystem health.
A recent terror warning highlights the potential danger of laptops and electronic devices on planes, sparking calls for improved security measures. Researchers like Uber advocate for airline monitoring systems to detect interfering signals inside aircraft cabins.
Research suggests that altruism, not panic, drives human behavior during disasters. In emergency situations, people prioritize helping others over self-preservation. Clarke's study highlights the importance of community expectations and trust in authorities to guide behavior during crises.
A team of researchers at Ohio State University has developed a new type of paint that changes color when it detects corrosion on the metal beneath, revealing tiny pockets of damage as shallow as 15 micrometers. This innovative material could help maintenance crews identify and address corrosion issues earlier, reducing the need for cos...
