New antibiotic holds promise against antibiotic-resistant infections
Estimates of deaths from methicillin-resistant Staphylococcus aureus (MRSA) in the United States range upwards of 19,000 annually. Around 1960, when Staphylococcus aureus developed resistance to first-generation ...

Scientists create first living organism that transmits added letters in DNA 'alphabet'
Scientists at The Scripps Research Institute (TSRI) have engineered a bacterium whose genetic material includes an added pair of DNA "letters," or bases, not found in nature. The cells of this unique bacterium ...
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 ...
New study revisits Miller-Urey experiment at the quantum level
For the first time, researchers have reproduced the results of the Miller-Urey experiment in a computer simulation, yielding new insight into the effect of electricity on the formation of life's building ...

Scientists create 'evolved' protein that may stop cancer from spreading
A team of Stanford researchers has developed a protein therapy that disrupts the process that causes cancer cells to break away from original tumor sites, travel through the blood stream and start aggressive ...
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.
Scientists shed light on controversial theory of protein structure
A team of chemists, biochemists and mathematicians at the University of Bristol have published a paper in the journal Nature Chemical Biology, which explores how protein structures are stabilised.
Quantum biology: Algae evolved to switch quantum coherence on and off
A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.
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.
Unlikely pairing—an antidepressant plus dye—yields tumor-targeting tool
A team of scientists has created a "conjugate" molecule—one stitched together from two separate molecules—that seeks out and blocks prostate cancer growth in lab animals.
