Parasitic wasps use calcium pump to block fruit fly immunity
Parasitic wasps switch off the immune systems of fruit flies by draining calcium from the flies' blood cells, a finding that offers new insight into how pathogens break through a host's defenses.
Discovery alters understanding of long-distance intercellular communication
(Phys.org) —In a finding likely to fundamentally reshape biologists' understanding of how vertebrate cells communicate, researchers at the Stanford University School of Medicine and the UC-San Francisco ...
Small in size, big on power: New microbatteries the most powerful yet
(Phys.org) —Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered ...
3-D printer builds synthetic tissues
A custom-built programmable 3D printer can create materials with several of the properties of living tissues, Oxford University scientists have demonstrated.
Study unlocks link between sex and female brain
An international team of scientists led by Gregg Adams at the University of Saskatchewan has discovered that a protein in semen acts on the female brain to prompt ovulation, and is the same molecule that ...
Lighting up the plant hormone 'command system'
Light is not only the source of a plant's energy, but also an environmental signal that instructs the growth behavior of plants. As a result, a plant's sensitivity to light is of great interest to scientists and their research ...
Pigeons' navigation skill not down to iron-rich beak cells: study
The theory that pigeons' famous skill at navigation is down to iron-rich nerve cells in their beaks has been disproved by a new study published in Nature.
Researchers present a shiny new tool for imaging biomolecules
At the heart of the immune system that protects our bodies from disease and foreign invaders is a vast and complex communications network involving millions of cells, sending and receiving chemical signals ...
Research on cilia heats up: Implications for hearing, vision loss and kidney disease
Experiments at Johns Hopkins have unearthed clues about which protein signaling molecules are allowed into hollow, hair-like "antennae," called cilia, that alert cells to critical changes in their environments.
Chaos proves superior to order
An international team of physicists, including researchers from the Universities of York and St. Andrews, has demonstrated that chaos can beat order - at least as far as light storage is concerned.
Neural activity in bats measured in-flight
Animals navigate and orient themselves to survive – to find food and shelter or avoid predators, for example. Research conducted by Dr. Nachum Ulanovsky and research student Michael Yartsev of the Weizmann ...
Startup links families with their independent seniors
A new way for families to stay close to independent elders that blends modern technology with old fashioned parcel post debuted on crowd-funding website Kickstarter Tuesday.
Electrical signals dictate optical properties
Researchers at the University of Southampton's Optoelectronics Research Centre (ORC) have created an artificial material, a metamaterial, with optical properties that can be controlled by electric signals.
Scientists show that graphene is highly efficient in converting light to electricity
Bottles, packaging, furniture, car parts... all made of plastic. Today we find it difficult to imagine our lives without this key material that revolutionized technology over the last century. There is wide-spread optimism ...
