Scientists make new discovery about bird evolution
A team of scientists has described the most exceptionally preserved fossil bird discovered to date, in a newly published article. The new specimen from the rich Early Cretaceous Jehol Biota (approximately 131 to 120 million years old) is referred to as Eoconfuciusornis, the oldest and most primitive member of the Confuciusornithiformes, a group of early birds characterized by the first occurrence of an avian beak.

Amazingly fast, cheap genome sequencing: Zika virus mosquito genome assembled from scratch
A team of scientists has developed a new way to sequence genomes, which can assemble the genome of an organism, entirely from scratch, dramatically cheaper and faster.

Lighting up antibiotic resistance
Carbapenems are among the 'antibiotics of last resort' and can fight infections for which other drugs have long lost their effectiveness. However, even carbapenem-resistant pathogenic strains have emerged over the last decades.

Hydrophobic proteins on virus surfaces can help purify vaccines
Through experimental and computational tests, new research expands on the theory of virus surface hydrophobicity. By being slightly water-repellent, the outer layers of proteins in virus capsids affect how it interacts with cells and the environment. Understanding this more can improve vaccine production and virus detection.

Botany: A stem's 'sense of self' contributes to shape
It is well known that as plants grow, their stems and shoots respond to outside signals like light and gravity. But if plants all have similar stimuli, why are there so many different plant shapes? Using simple mathematical ideas, researchers have constructed a framework that explains and quantifies the different shapes of plant stems.

Designer proteins fold DNA: Biophysicists construct complex hybrid structures using DNA and proteins
Scientists have developed a new method that can be used to construct custom hybrid structures using DNA and proteins. The method opens new opportunities for fundamental research in cell biology and for applications in biotechnology and medicine.

Scientists reveal hidden structures in bacterial DNA
Researchers have described the 3D structure of the genome in the extremely small bacteria Mycoplasma pneumoniae. They discovered previously unknown arrangements of DNA within this tiny bacteria, which are also found in larger cells. Their findings suggest that this type of organization is a universal feature of living cells.

Immune study in chickens reveals key hurdle for Campylobacter vaccine effort
The immune response of farmed chickens does not develop fast enough to fight off Campylobacter during their short lifespan, new research has found. The findings have important implications in the challenge towards developing a poultry vaccine for the bug, which is the UK's leading cause of food poisoning.

Self-sustaining bacteria-fueled power cell created
Researchers have developed the next step in microbial fuel cells (MFCs) with the first micro-scale self-sustaining cell, which generated power for 13 straight days through symbiotic interactions of two types of bacteria.
