Rare byproduct of marine bacteria kills cancer cells by snipping their DNA
(Phys.org) —Yale University researchers have determined how a scarce molecule produced by marine bacteria can kill cancer cells, paving the way for the development of new, low-dose chemotherapies.
New research rejects 80-year theory of 'primordial soup' as the origin of life
For 80 years it has been accepted that early life began in a 'primordial soup' of organic molecules before evolving out of the oceans millions of years later. Today the 'soup' theory has been over turned in a pioneering paper ...
Novel bacterial 'language' discovered
(Phys.org) —LMU researchers have identified a yet unknown bacterial cell-cell communication system.
Metabolism may have started in our early oceans before the origin of life
The chemical reactions behind the formation of common metabolites in modern organisms could have formed spontaneously in the earth's early oceans, questioning the events thought to have led to the origin ...
Accidental discovery produces durable new blue pigment for multiple applications
An accidental discovery in a laboratory at Oregon State University has apparently solved a quest that over thousands of years has absorbed the energies of ancient Egyptians, the Han dynasty in China, Mayan ...
Scientists create renewable fossil fuel alternative using bacteria
The development is a step towards commercial production of a source of fuel that could one day provide an alternative to fossil fuels.
Niacin, the fountain of youth
The vitamin niacin has a life-prolonging effect, as Michael Ristow has demonstrated in roundworms. From his study, the ETH-Zurich professor also concludes that so-called reactive oxygen species are healthy, ...
How Did Evolution Begin?
Scientists Reproduce a Building Block of Life in Laboratory
(PhysOrg.com) -- NASA scientists studying the origin of life have reproduced uracil, a key component of our hereditary material, in the laboratory.
Self-assembling anti-cancer molecules created in minutes
Researchers have developed a simple and versatile method for making artificial anti-cancer molecules that mimic the properties of one of the body's natural defence systems.
Simpler times: Did an earlier genetic molecule predate DNA and RNA?
(PhysOrg.com) -- In the chemistry of the living world, a pair of nucleic acidsDNA and RNAreign supreme. As carrier molecules of the genetic code, they provide all organisms with a mechanism for ...
Researchers find a clue to how life turned left
Researchers analyzing meteorite fragments that fell on a frozen lake in Canada have developed an explanation for the origin of life's handedness why living things only use molecules with specific orientations. ...
Scientists discover new clue to the chemical origins of life
Organic chemists at the University of York have made a significant advance towards establishing the origin of the carbohydrates (sugars) that form the building blocks of life.
Scientists use 3D printing to make artificial blood vessels
The tangled highway of blood vessels that twists and turns inside our bodies, delivering essential nutrients and disposing of hazardous waste to keep our organs working properly has been a conundrum for scientists ...
