Polyethylene waste could be a thing of the past      (via sciencedaily.com)     Original source 

Experts have developed a way of using polyethylene waste (PE) as a feedstock and converted it into valuable chemicals, via light-driven photocatalysis. PE is the most widely used plastic in the world including for daily food packaging, shopping bags and reagent bottles, and the researchers say that while recycling of PE is still in early development, it could be an untapped resource for re-use.

When is an aurora not an aurora?      (via sciencedaily.com)     Original source 

While auroras occur at high latitude, the associated phenomena Steve and the picket fence occur farther south and at lower altitude. Their emissions also differ from aurora. A physics graduate student has proposed a physical mechanism behind these emissions, and a rocket launch to test the theory. She argues that an electric field in the upper atmosphere parallel to Earth's magnetic field could explain the green picket fence spectrum and perhaps Steve and the enhanced aurora.

Veins of bacteria could form a self-healing system for concrete infrastructure      (via sciencedaily.com)     Original source 

In hopes of producing concrete structures that can repair their cracks, researchers are putting a new twist on an old trick for improving the durability of concrete. Fiber reinforcement has been around since the first masons were mixing horsehair into their mud. But this research team is taking this method to the next level by turning reinforcing fibers into a living tissue system that rushes concrete-healing bacteria to the site of cracks to repair the damage.

First observation of structures resulting from 3D domain swapping in antibody light chains      (via sciencedaily.com)     Original source 

Antibodies hold promise as therapeutic agents. However, their tendency to aggregate poses significant challenges to drug development. In a groundbreaking study, researchers now provide novel insights into the structure formed due to 3D domain swapping of the antibody light chain, the part of the antibody contributing to antigen binding. Their findings are expected to lead to improvements in antibody quality and the development of novel drugs.

Scholars say it's time to declare a new epoch on the moon, the 'lunar Anthropocene'      (via sciencedaily.com)     Original source 

According to anthropologists and geologists, it's time to acknowledge humans have become the dominant force shaping the moon's environment by declaring a new geological epoch for the moon: the Lunar Anthropocene. They argue the new epoch may have dawned in 1959 when the USSR's unmanned spacecraft Luna 2 alighted on the lunar surface.

Adapting to hypoxia: Zooplankton influence the efficiency of the biological carbon pump in the Humboldt Current off Peru      (via sciencedaily.com)     Original source 

Marine organisms play a crucial role in the global carbon cycle. Phytoplankton absorb carbon dioxide from the atmosphere and sequester it in organic matter that sinks to the deep ocean where it can be stored for long periods of time. Until now, this process -- the biological carbon pump -- was thought to be particularly efficient in oxygen-poor areas. A new study suggests that the influence of certain zooplankton species on the biological carbon pump has been underestimated.

Breakthrough nanobody technology against liver inflammation      (via sciencedaily.com)     Original source 

Researchers have developed a technique based on nanobody technology to prevent liver inflammation. Nanobodies, or single-domain antibodies, are fragments of antibodies that can selectively bind to a specific antigen. Because they are simple to produce and react in very specific ways, they are often used in various biotechnological, therapeutic and diagnostic applications.

New insights into Zebra mussel attachment fibers offer potential solutions to combat invasive species, develop sustainable materials      (via sciencedaily.com)     Original source 

A recent study has revealed that an unlikely event, occurring over 12 million years ago played an important role in shaping one of Canada's most damaging invasive species. Zebra and quagga mussels, belonging to the Dreissenid family, are widespread freshwater invasive species throughout North America that present a significant danger to native ecosystems by competing for resources. Using a fibrous anchor called a byssus, Dreissenid mussels contribute to biofouling on surfaces and obstruct intake structures in power stations and water treatment plants.
