We need your help to achieve the goal of growing our online, geographically searchable database of resources and support for cancer patients, their families and caregivers. Whether you're in the initial phase of shock, in the battle, or handling the aftermath of cancer, our resources take out the stress of searching multiple places and thousands of online listings.
The parasite Toxoplasma gondii need not infect a host immune cell to alter its behavior, according to a new study from the University of Pennsylvania School of Veterinary Medicine.
Bees are pollinators of many plants, but their diversity and density is declining. A team led by Göttingen investigated their foraging behaviour in agricultural landscapes. They found that honey bees prefer strawberry fields, even if flowering next to oilseed rape fields. Only when oilseed rape was in full bloom were fewer honey bees in the strawberries. Wild bees, on the other hand, consistently chose the strawberry field. Results appeared in the journal Agriculture, Ecosystems & Environment.
Lithium dendrites cause poor performance and even explosions in batteries with flammable liquid electrolytes. How these dendrites grow, even with a solid electrolytes, is still a mystery, but materials engineers at MTU and Oak Ridge study the conditions that enable dendrites and how to stop them.
A team led by researchers from the Yale School of Forestry & Environmental Studies recently authored a paper featured in Science that outlines how green chemistry is essential for a sustainable future.
Physicists at Ludwig-Maximilians-Universitaet (LMU) in Munich, together with colleagues at Saarland University, have successfully demonstrated the transport of an entangled state between an atom and a photon via an optic fiber over a distance of up to 20 km -- thus setting a new record.
Registry data -- of sufficient quality -- are suitable for the extended benefit assessment of drugs. Rapid report shows how routine practice data should be collected and processed.
Like animals and humans, plants possess a kind of immune system. It can e.g. recognize pathogenic fungi by the chitin in their cell walls, triggering disease resistance. Some fungi hide from the immune system by modifying some of the chitin building blocks, converting chitin into chitosan. Researchers of the University of Münster now found that plants can react to a certain pattern in this chitosan, stimulating their immune system.
Finnish research team maps neural activity in response to watching horror movies. A study conducted by the University of Turku shows the top horror movies of the past 100 years, and how they manipulate brain activity.
Researcher of the Netherlands Institute for neuroscience found that myelin, the sheath around neurons, creates a coaxial cable producing multiple waves of electrical potentials traveling in a more complicated manner than was envisioned earlier. These findings allow us to create better theories and tools to understand demyelinating diseases, including the most common neurological disorder, multiple sclerosis. The paper has been published in the prestigious scientific journal Cell.
Human pressure on the world's ocean accelerated sharply at the start of the 21st century and shows no sign of slowing, according to a comprehensive new analysis on the state of the ocean.Scientists have dubbed the dramatic rise the "Blue Acceleration". The researchers from the Stockholm Resilience Centre, Stockholm University, synthesized 50-years of data from shipping, drilling, deep-sea mining, aquaculture, bioprospecting and much more. The results are published in the journal One Earth, 24 January.
