(Phys.org) —The most luminous galaxies in our universe are not particularly bright in the visible. Most of their energy output (which can be hundreds or even thousands of times more than our Milky Way's) ...
Modern-day alchemy: A recipe for a new superheavy element
Even though nearly 80 years have passed since the discovery of Technetium, the first "synthetic" element, the periodic table of elements remains a work in progress.
Near-Earth asteroid is really a comet
Some things are not always what they seem—even in space. For 30 years, scientists believed a large near-Earth object was an asteroid. Now, an international team including Joshua Emery, assistant professor ...
Moving genes have scientists seeing spots
An international team of scientists led by the UK's John Innes Centre and including scientists from Australia, Portugal, China and Italy has perfected a way of watching genes move within a living plant cell.
Finding could potentially make iPS cells safer for use in humans
Induced pluripotent stem cells, or iPS cells, are a hot commodity right now in biology.
Mammals contain cells whose primary function is to kill other cells in the body. The so-called Natural Killer (NK) cells are highly important in defending our bodies against viruses or even cancer. Scientists ...
Identification of a plant-specific nanomachine regulating nuclear movement
A group led by Professor Ikuko Hara-Nishimura (Department of Botany, Graduate School of Science) revealed the molecular mechanism underlying nuclear movement in plants.
Protein lifetime and the stability of cell structures
Researchers create three-dimensional model of bacterium
Certain bacteria can build such complex membrane structures that, in terms of complexity and dynamics, look like eukaryotes, i.e., organisms with a distinct membrane-bound nucleus. Scientists from Heidelberg University and ...
Shedding new light on the brightest objects in the universe
A Dartmouth-led team of astrophysicists has discovered the extent to which quasars and their black holes can influence their galaxies.
Making big 'Schroedinger cats': Quantum research pushes boundary by testing micro theory for macro objects
Since Erwin Schroedinger's famous 1935 cat thought experiment, physicists around the globe have tried to create large scale systems to test how the rules of quantum mechanics apply to everyday objects.
Stem cell clues uncovered
Proper tissue function and regeneration is supported by stem cells, which reside in so-called niches. New work from Carnegie's Yixian Zheng and Haiyang Chen identifies an important component for regulating stem cell niches, ...
Multinational effort underway to build synthetic yeast using artificial chromosomes
How to build your gate: New approach solves large molecular puzzles
(Phys.org) —It's a parent's nightmare: opening a Lego set and being faced with 500 pieces, but no instructions on how to assemble them into the majestic castle shown on the box. Thanks to a new approach ...
