Nanotube coating helps shrink mass spectrometers
Nanotechnology is advancing tools likened to Star Trek's "tricorder" that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety.
Oldest bit of crust firms up idea of a cool early Earth
With the help of a tiny fragment of zircon extracted from a remote rock outcrop in Australia, the picture of how our planet became habitable to life about 4.4 billion years ago is coming into sharper focus.
Scientists stitch up photosynthetic megacomplex
When sunlight strikes a photosynthesizing organism, energy flashes between proteins just beneath its surface until it is trapped as separated electric charges. Improbable as it may seem these tiny hits of ...
Maya Long Count calendar and European calendar linked using carbon-14 dating
(Phys.org) —The Maya are famous for their complex, intertwined calendric systems, and now one calendar, the Maya Long Count, is empirically calibrated to the modern European calendar, according to an international ...
Mapping the living cell: New technique pinpoints protein locations, helping scientists figure out their functions
To get a clear picture of what's happening inside a cell, scientists need to know the locations of thousands of proteins and other molecules. MIT chemists have now developed a technique that can tag all of ...
Chemists find smallest number of water molecules needed to form an ice crystal
Study resets date of earliest animal life by 30 million years
University of Alberta researchers have uncovered physical proof that animals existed 585 million years ago, 30 million years earlier than all previous established records show.
Study of biomarker development in mice provides a roadmap for a similar approach in humans
Researchers at Fred Hutchinson Cancer Research Center have demonstrated in mice that the performance of a novel biomarker-development pipeline using targeted mass spectrometry is robust enough to support the use of an analogous ...
Scientists unlock mystery of how the 22nd amino acid is produced
The most recently discovered amino acid, pyrrolysine, is produced by a series of just three chemical reactions with a single precursor the amino acid lysine, according to new research.
Researchers discover water on the moon is widespread, similar to Earth's
Researchers at the University of Tennessee, Knoxville, are once again turning what scientists thought they knew about the moon on its head.
Beewolves protect their offspring with antibiotics
Digger wasps of the genus Philanthus, so-called beewolves, house beneficial bacteria on their cocoons that guarantee protection against harmful microorganisms. Scientists of the Max Planck Institute for Ch ...
Chemical snapshot: Murchison meteorite reveals diversity of early Solar System
New Perspectives on Cancer Surgery
(PhysOrg.com) -- Instead of the classic scalpel, surgeons can also operate with an electroscalpel. A significant advantage to this technique is that while a cut is being made, blood vessels are closed off ...
Komodo even more deadly than thought: Research
The carnivorous reptiles (Varanus komodoensis) are known to bite prey and release them, leaving them to bleed to death from their wounds: the victims are reported to go into shock before the dragons kill a ...
