University of Warwick astronomers have discovered an extremely rare, high mass, compact binary star system only ~150 light years away. These two stars are on a collision course to explode as a type 1a supernova, appearing 10 times brighter than the moon in the night sky.   Type 1a supernovae are a special class of cosmic explosion, famously used as ‘standard candles’ to measure distances between Earth and their host galaxies. They occur when a white dwarf (the dense remnant core of a star) accumulates too much mass, is unable to withstand its own ...

Storm forecasting is traditionally based on studying atmospheric conditions but ground-breaking research that also looks at land surface conditions is set to transform early warning systems in tropical regions. This will enable communities to better adapt to the destructive impacts of climate change. The new study led by the UK Centre for Ecology & Hydrology (UKCEH) has shown that a large contrast in soil moisture levels over a range of hundreds of kilometres results in atmospheric changes that increase rainfall area and amount in several megastorm hotspots globally. This increase ranges from 10 to 30% depending on the region and size ...

An 11-year-old neutered male Asian small-clawed otter fell down the stairs while sleeping, after which it developed left-sided paralysis. Initial treatment involved once daily administration of prednisolone at 0.5 mg/kg. Despite slight clinical sign improvements by day 10, paralysis persisted. MRI (T2WI) identified a well-defined, hyper-intense lesion on the left side within the spinal cord at the C2-3 intervertebral level. Based on CT and MRI findings, fibrocartilaginous embolus (FCE) was suspected. Prednisolone was then tapered and by day 23 of illness, the otter was able to walk ...

Fluids play a crucial role in industrial processes like cooling, heating, and mixing. Traditionally, most industries would utilize Newtonian fluids—which have a constant viscosity—for such processes. However, many are now adopting viscoelastic fluids, which can behave as both liquids and elastic materials. These fluids can suppress turbulence in simple flows like straight pipes or channels, leading to reduced wall friction. This “drag reduction effect” has attracted significant interest due to its potential to enhance energy efficiency. To advance the industrial applications ...

Retired people who habitually exercise are more able to fight the impacts of mental fatigue, new research suggests.   In a paper published in the Journal of Aging and Physical Activity, a team of researchers from the University of Birmingham and the University of Extremadura in Spain worked with groups of adults to find out whether age would increase, and regular exercise would decrease the impact of mental fatigue on a series of cognitive and physical performance tests.   In the first study, sedentary men between 65 and 79 performed worse in cognitive and physical tests compared to 52-64 year olds, with these ...

From seat cushions to mattresses to insulation, foam is everywhere — even if we don’t always see it. Now, researchers at The University of Texas at Dallas have fused chemistry with technology to create a 3D-printed foam that is more durable and more recyclable than the polymer foam found in many everyday products. The research, which appears in the March 1 print edition of RSC Applied Polymers, a journal of the Royal Society of Chemistry, focused on creating a sturdy but lightweight foam that could be 3D-printed, a method that is still largely unexplored in commercial manufacturing, said the study’s co-lead author, UT Dallas doctoral student Rebecca Johnson ...

How does a robotic arm or a prosthetic hand learn a complex task like grasping and rotating a ball? The challenge for the human, prosthetic or robotic hand has always been to correctly learn to control the fingers to exert forces on an object. The sensitive skin and nerve endings that cover our hands have been attributed with helping us learn and adapt our manipulation, so roboticists have insisted on incorporating sensors on robotic hands. But–given that you can still learn to handle objects with gloves on– there must be something else at play.  This mystery is what inspired researchers in the ValeroLab in the Viterbi School of Engineering ...
