Creating desirable materials requires salt, but not space
(PhysOrg.com) -- When synthesizing specialized materials for energy-packed batteries, the problem is the template. The pattern for self-assembling the highly desired nanometer-sized spheres falls...
View ArticleStudy reveals new role for RNA interference during chromosomal replication
At the same time that a cell's DNA gets duplicated, a third of it gets super-compacted into repetitive clumps called heterochromatin. This dense packing serves to repress or "silence" the DNA sequences...
View ArticleResearchers build transparent, super-stretchy skin-like sensor (w/ video)
Imagine having skin so supple you could stretch it out to more than twice its normal length in any direction - repeatedly - yet it would always snap back completely wrinkle-free when you let go of it....
View ArticleHow do green algae react to carbon nanotubes?
Nanoparticles such as carbon nanotubes (CNT), which are found in an ever-increasing number of products, are ending up more and more frequently in our surroundings. If and how they affect aquatic...
View ArticleHow old yeast cells send off their daughter cells without the baggage of old age
The accumulation of damaged protein is a hallmark of aging that not even the humble baker's yeast can escape. Yet, aged yeast cells spawn off youthful daughter cells without any of the telltale protein...
View ArticleALMA early science result reveals starving galaxies
(PhysOrg.com) -- Astronomers using the partially completed ALMA observatory have found compelling evidence for how star-forming galaxies evolve into 'red and dead' elliptical galaxies, catching a large...
View ArticleBlack hole jets
(PhysOrg.com) -- Black holes are irresistible sinks for matter and energy. They are so dense that not even light can escape from their gravitational clutches. Massive black holes (equal to millions or...
View ArticleStellar embryos
(PhysOrg.com) -- Stars form as gravity coalesces the gas and dust in interstellar clouds until the material produces clumps dense enough to become stars. But precisely how this happens, and whether or...
View ArticleWorld's first magnetic soap produced
Scientists from the University of Bristol have developed a soap, composed of iron rich salts dissolved in water, that responds to a magnetic field when placed in solution. The soap's magnetic...
View ArticleFilmmaker sounds alarm over ocean of plastic
On Midway atoll in the North Pacific, dozens of young albatross lie dead on the sand, their stomachs filled with cigarette lighters, toy soldiers and other small plastic objects their parents have...
View ArticleThe dance of the chaperones: Scientists identify key player of protein folding
Proteins are the molecular building blocks and machinery of cells and involved in practically all biological processes. To fulfil their tasks, they need to be folded into a complicated...
View ArticleInterest in gourmet fungi is mushrooming
With its large clumps of cascading white tendrils, the Hericium erinaceus looks less like a mushroom and more like a lion's mane (its nickname).
View ArticleOrder from disorder
NPL and University of Leicester scientists have explored a new way of ordering proteins for materials engineering at the nanoscale, using natural biological phenomena as a guide.
View ArticleNanotube 'sponge' has potential in oil spill cleanup
(Phys.org) -- A carbon nanotube sponge that can soak up oil in water with unparalleled efficiency has been developed with help from computational simulations performed at the Department of Energy's...
View ArticleScientists sound acid alarm for plankton
The microscopic organisms on which almost all life in the oceans depends could be even more vulnerable to increasingly acidic waters than scientists realised, according to a new study.
View ArticleThe anatomy of a stellar outflow
(Phys.org) -- Astronomers used to think that star formation simply involved the gradual coalescence of material under the influence of gravity. No longer. Making a new star is a complex process, among...
View ArticleNeighbor galaxies may have brushed closely: research
(Phys.org) -- Two of our Milky Way's neighbor galaxies may have had a close encounter billions of years ago, recent studies with the National Science Foundation's Green Bank Telescope (GBT) indicate....
View ArticleHidden galactic nuclei
(Phys.org) -- At the core of most galaxies including our own Milky Way is a massive black hole. Material falling into the environment of the black hole heats up, and can radiate dramatically, sometimes...
View ArticleAll about dust
(Phys.org)—The space between stars is not empty—it contains copious amounts of gas and dust. Astronomers estimate that about 5-10% of the total mass of our Milky Way galaxy is contained in the...
View ArticleSaturn's B-ring: Taking a closer look
(Phys.org)—Clumpy particles in Saturn's B-ring provide stark contrast to the delicately ordered ringlets seen in the rest of this view presented by the Cassini spacecraft.
