Phys.org / Unseen planet or brown dwarf may have hidden 'rare' fading star
One of the longest stellar dimming events ever observed was likely caused by the gigantic saucer-like rings of either an unseen brown dwarf or "super-Jupiter" blocking its host star's light, astronomers say. For decades, ...
Phys.org / White-nose syndrome puzzle solved: Biological mechanisms behind devastating bat disease revealed
Millions of bats in North America have died from white-nose syndrome, and a new study from the University of Waterloo explores why and how the fungal disease has devastated bat populations on this continent, while it has ...
Medical Xpress / Growth of spreading pancreatic cancer is fueled by 'underappreciated' epigenetic changes, shows study
In a lab-grown cell study focused on potential new treatment targets for halting the spread of most pancreatic cancers, Johns Hopkins Medicine scientists report they have found that a gene called KLF5 (Krueppel-like factor ...
Tech Xplore / A microfluidic chip monitors gases using integrated, motionless pumps
A new microscale gas chromatography system integrates all fluidic components into a single chip for the first time. The design leverages three Knudsen pumps that move gas molecules using heat differentials to eliminate the ...
Phys.org / When heat flows backwards: A neat solution for hydrodynamic heat transport
When we think about heat traveling through a material, we typically picture diffusive transport, a process that transfers heat from high-temperature to low-temperature as particles and molecules bump into each other, losing ...
Medical Xpress / Why visceral fat triggers diabetes: Study points to loss of protective macrophages
Scientists at the University of Pittsburgh School of Medicine discovered a surprising new way the body can fight insulin resistance and diabetes—by boosting a special type of "good" immune cell in fat tissue.
Phys.org / Mars' 'young' volcanoes prove more complex than scientists once thought
What appears to be a single volcanic eruption is often the result of complex processes operating deep beneath the surface, where magma moves, evolves, and changes over long periods of time. To fully understand how volcanoes ...
Phys.org / Strawberry guava prevents natural forest generation in Madagascar, project reveals
Rice University biologist Amy Dunham has spent decades studying the mountainous rainforests of Madagascar's Ranomafana National Park, a UNESCO World Heritage site that was designated a national park in 1991. In a project ...
Medical Xpress / African indigenous foods that fight inflammation may help people with diabetes
African indigenous food groups present an exciting area to explore when it comes to taste and nutrition. They may even offer potential as nutritional therapy for people with health problems.
Medical Xpress / Want a tall, smart child? How IVF tests are selling a dream
Prospective parents are being marketed genetic tests that claim to predict which IVF embryo will grow into the tallest, smartest or healthiest child. But these tests cannot deliver what they promise. The benefits are likely ...
Phys.org / Scientists reveal formation mechanism behind spherical assemblies of nanocrystals
From table salt to snowflakes, and from gemstones to diamonds—we encounter crystals everywhere in daily life, usually cubic (table salt) or hexagonal (snowflakes). Researchers from Noushine Shahidzadeh's group at the UvA ...
Phys.org / Ambitious climate action could save 1.32 million lives a year by 2040
Ambitious climate action to improve global air quality could save up to 1.32 million lives per year by 2040, according to a new study. The research, led by Cardiff University, shows how developing countries rely heavily on ...
