Antibiotic resistance is one of medicine’s most pressing problems. Now, a team from Korea is tackling this in a unique way: using bacteria to fight bacteria.
Researchers face a fundamental challenge as they seek to scale up human tissue regeneration from small lab samples to full-size tissues and organs: how to establish a vascular system that delivers blood deep into the developing tissue. Researchers have now successfully turned to plants, culturing beating human heart cells on spinach leaves that were stripped of plant cells. …
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.
More than 2 million procedures every year take place around the world to heal bone fractures and defects from trauma or disease, making bone the second most commonly transplanted tissue after blood. To help improve the outcomes of these surgeries, scientists have developed a new grafting material from sea urchin spines.
Tasty, versatile, and rich in essential omega-3 fatty acids: salmon is one of the most popular edible fish of all. Shops sell fish caught in the wild, but their main produce is salmon from breeding farms which can pollute rivers, lakes and oceans. Just how big is the problem? Scientists are working to answer this question by examining the dissolved organic compounds which enter Chile’s rivers from salmon farms. They warn that these substances are placing huge strain on ecosystems and are changing entire biological communities.
100% natural, 100% gluten free – get ready for the battle of the grain. Researchers have resolved the science behind a new bread-baking recipe. The method for making gluten-free bread uses rice-flour to produce bread with a similar consistency and volume to traditional wheat-flour loaves.
A species of unicellular ciliate has found a special trick to make use of the cellular machinery in seemingly impossible ways. Researchers have for the first time described a mechanism in detail how so called “junk”-DNA is transcribed before being degraded – and this mechanism is remarkably clever.
Researchers are nebulizing soybean aphids with RNA to speed the process of discovering the function of many mystery genes.
Through genetic mutations microorganisms normally have the ability to develop new properties over a short time scale. Researchers now show that microbes in the deep seabed grow in slow motion with generation times of up to 100 years.
What can the forests of Scandinavia possibly offer to migrants in faraway refugee camps? Clean water may be one thing, suggests a new report.
Sulforaphane, a dietary compound from broccoli that’s known to help prevent prostate cancer, may work through its influence on long, non-coding RNAs, report scientists. This is another step forward in a compelling new area of study on the underlying genetics of cancer development and progression.
