Hydrophobic proteins on virus surfaces can help purify vaccines

Fri, 24 Mar 2017 00:00:00 EDT

(Michigan Technological University) 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.



Chance find has big implications for water treatment's costs and carbon footprint

Fri, 24 Mar 2017 00:00:00 EDT

(Engineering and Physical Sciences Research Council) A type of bacteria accidentally discovered during research supported by the Engineering and Physical Sciences Research Council could fundamentally reshape efforts to cut the huge amount of electricity consumed during wastewater clean-up.The discovery has upended a century of conventional thinking. The microorganisms -- 'comammox' (complete ammonia oxidizing) bacteria -- can completely turn ammonia into nitrates.



Data security in medical studies: IT researchers break anonymity of gene databases

Fri, 24 Mar 2017 00:00:00 EDT

(Saarland University) DNA profiles can reveal a number of details about individuals. There are laws in place that regulate the trade of gene data. However, these laws do not apply to an equally relevant type of genetic data, so-called microRNAs. This means that anonymity needs to be strictly maintained in microRNA studies as well. Researchers from Saarland University are able to show that a few microRNA molecules are sufficient to draw conclusions about study participants.



New lab-on-a-chip platform seeks to improve pathogen detection

Fri, 24 Mar 2017 00:00:00 EDT

(Future Science Group) Researchers from the Fraunhofer Institute have developed a new prototype lab-on-a-chip platform for the easy and versatile detection of molecular pathogens.

In a sample of blood, researchers probe for cancer clues

Thu, 23 Mar 2017 00:00:00 EDT

(University of California - Berkeley) One day, patients may be able to monitor their body's response to cancer therapy just by having their blood drawn. A new study, led by bioengineers at UC Berkeley, has taken an important step in that direction by measuring a panel of cancer proteins in rare, individual tumor cells that float in the blood.

Thu, 23 Mar 2017 00:00:00 EDT

(Harvard John A. Paulson School of Engineering and Applied Sciences) 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 from the Harvard SEAS constructed a framework that explains and quantifies the different shapes of plant stems.
