Shell scientist receives prestigious award to develop alternative carbon management technologies

Shell Scientist Christian A. Davies, Ph.D., has been named the recipient of the 2021 Edith and Peter O'Donnell Award in Technology Innovation from TAMEST (The Academy of Medicine, Engineering and Science of Texas). He was chosen for his development of a broad suite of alternative carbon management technologies to reduce emissions for a lower carbon future.

Researchers map platypus genome to understand its bizarre characteristics

Often considered the world's oddest mammal, Australia's beaver-like, duck-billed platypus exhibits an array of bizarre characteristics: it lays eggs instead of giving birth to live babies, sweats milk, has venomous spurs and is even equipped with 10 sex chromosomes.

Scientists resolve long-standing debate over key mechanism involved in gene silencing

Scientists from Massachusetts General Hospital (MGH) have resolved a long-standing debate over how crucial gene-silencing protein detects its targets.

Scientists develop novel approach to acquire fluorescence lifetime images

Fluorescence microscopy is widely used in biochemistry and life sciences because it allows scientists to directly observe cells and certain compounds in and around them. Fluorescent molecules absorb light within a specific wavelength range and then re-emit it at the longer wavelength range.

Controlling biological functions of DNA with the aid of light

DNA (deoxyribonucleic acid) is the basis of life on earth. The function of DNA is to store all the genetic information, which an organism needs to develop, function and reproduce. It is essentially a biological instruction manual found in every cell.

HKU researchers develop new drug discovery strategy targeting membrane proteins on live cells

A research team led by Dr Xiaoyu LI from the Research Division for Chemistry, Faculty of Science, in collaboration with Professor Yizhou LI from School of Pharmaceutical Sciences, Chongqing University and Professor Yan CAO from School of Pharmacy, Second Military Medical University in Shanghai has developed a new drug discovery method targeting membrane proteins on live cells.

New study reveals a troubling aspect of microplastics

As the plastic in our oceans breaks up into smaller and smaller bits without breaking down chemically, the resulting microplastics are becoming a serious ecological problem.

Many light smokers meet the criteria for nicotine addiction

Even people who consider themselves to be casual cigarette smokers may be addicted, according to current diagnostic criteria. Researchers at Penn State College of Medicine and Duke University found that many light smokers -- those who smoke one to four cigarettes per day or fewer -- meet the criteria for nicotine addiction and should therefore be considered for treatment.

New project to study origin and major pathways of pollutants into coastal lagoons

A scientific project led by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona and the Universidad Politécnica de Cartagena will study the major pathways delivering nutrients, trace metals and pollutants.

Scientists identify new weapon to fight against antibiotic-resistant bacteria

As scientists around the globe wage war against a novel, deadly virus, one University of Colorado Boulder lab is working on new weapons to battle a different microbial threat: a rising tide of antibiotic-resistant bacteria which, if left unchecked, could kill an estimated 10 million people annually by 2050.

Researchers use different colors of light to control gut bacteria genes

Baylor College of Medicine researcher Meng Wang had already shown that bacteria that make a metabolite called colanic acid (CA) could extend the lifespan of worms in her lab by as much as 50%, but her collaboration with Rice University synthetic biologist Jeffrey Tabor is providing tools to answer the bigger question of how the metabolite imparts longer life.
