Published Researchers 3D print components for a portable mass spectrometer
(via sciencedaily.com)
Original source 
Researchers 3D printed a mini quadrupole mass filter, a key component of a mass spectrometer, that performs as well as some commercial-grade devices. It can be fabricated in hours for a few dollars and is one step toward producing a portable mass spectrometer that could enable effective medical diagnoses or chemical analyses in remote areas.
Published Treating tuberculosis when antibiotics no longer work
(via sciencedaily.com)
Original source 
A research team has detected various substances that have a dual effect against tuberculosis: They make the bacteria causing the disease less pathogenic for human immune cells and boost the activity of conventional antibiotics.
Published Springs aboard -- gently feeling the way to grasp the microcosmos
(via sciencedaily.com)
Original source 
The integration of mechanical memory in the form of springs has for hundreds of years proven to be a key enabling technology for mechanical devices (like clocks), achieving advanced functionality through complex autonomous movements. In our times, the integration of springs in silicon-based microtechnology has opened the world of planar mass-producible mechatronic devices from which we all benefit, via air-bag sensors for example.
Published Nematode proteins shed light on infertility
(via sciencedaily.com)
Original source 
Biologists developed a method for illuminating the intricate interactions of the synaptonemal complex in the nematode C. elegans. The authors identified a trio of protein segments that guide chromosomal interactions, and pinpointed the location where they interact with each other. Their novel method uses a technique known as genetic suppressor screening, which can serve as a blueprint for research on large cellular assemblies that resist traditional structural analysis.
Published The choreography connecting kelp forests to the beach
(via sciencedaily.com)
Original source 
A new study uncovers a symphony of synchrony between the kelp forest and beach, with broader implications for the beach food web as the climate changes.
Published Vitamin discovered in rivers may offer hope for salmon suffering from thiamine deficiency disease
(via sciencedaily.com)
Original source 
Researchers have discovered vitamin B1 produced by microbes in rivers, findings that may offer hope for vitamin-deficient salmon populations.
Published Seismic and infrasonic signals used to characterize Nord Stream pipeline events
(via sciencedaily.com)
Original source 
A new study provides further evidence that the Nord Stream seismic signals came from a complex source. The signals lasted longer than would be expected from a single explosive source, the researchers say, and were more like the signals detected from an underwater volcano or a pipeline venting gas.
Published 'Giant' predator worms more than half a billion years old discovered in North Greenland
(via sciencedaily.com)
Original source 
Fossils of a new group of animal predators have been located in the Early Cambrian Sirius Passet fossil locality in North Greenland. These large worms may be some of the earliest carnivorous animals to have colonized the water column more than 518 million years ago, revealing a past dynasty of predators that scientists didn't know existed.
Published Study reveals clues to how Eastern equine encephalitis virus invades brain cells
(via sciencedaily.com)
Original source 
Researchers have determined how Eastern equine encephalitis virus attaches to a receptor it uses to enter and infect cells. The findings laid the groundwork for a receptor decoy molecule that protects mice from encephalitis caused by the virus.
Published Functional semiconductor made from graphene
(via sciencedaily.com)
Original source 
Researchers have created the first functional semiconductor made from graphene, a single sheet of carbon atoms held together by the strongest bonds known. The breakthrough throws open the door to a new way of doing electronics.
Published Researchers improve seed nitrogen content by reducing plant chlorophyll levels
(via sciencedaily.com)
Original source 
Chlorophyll plays a pivotal role in photosynthesis, which is why plants have evolved to have high chlorophyll levels in their leaves. However, making this pigment is expensive because plants invest a significant portion of the available nitrogen in both chlorophyll and the special proteins that bind it. As a result, nitrogen is unavailable for other processes. In a new study, researchers reduced the chlorophyll levels in leaves to see if the plant would invest the nitrogen saved into other process that might improve nutritional quality.
Published How does corrosion happen? New research examines process on atomic level
(via sciencedaily.com)
Original source 
New research reveals how corrosion happens on the atomic level.
Published Path-following performance of autonomous ships
(via sciencedaily.com)
Original source 
With recent requirements for reducing greenhouse gas emissions of autonomous ships, an emerging body of research is focused on assessing the path-following performance of maritime autonomous surface ships (MASS) at low speeds under adverse weather conditions. To combat the poor accuracy of traditional methods, in a new study, researchers investigated the path-following performance of MASS using a free-running computational fluid dynamics model. Their findings can help ensure safer autonomous navigation with reduced propulsion power.
Published Microbial awakening restructures high-latitude food webs as permafrost thaws
(via sciencedaily.com)
Original source 
Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to fungal-based food webs for several high-latitude species, with potential indirect effects on nutrient cycling and ecosystem function.
Published Bacteria load their syringes
(via sciencedaily.com)
Original source 
Many bacterial pathogens use small injection apparatuses to manipulate the cells of their hosts, such as humans, so that they can spread throughout the body. To do this, they need to fill their syringes with the relevant injection agent. A technique that tracks the individual movement of proteins revealed how bacteria accomplish this challenging task.
Published Early primates likely lived in pairs
(via sciencedaily.com)
Original source 
Primate social organization is more flexible than previously assumed. According to a new study, the first primates probably lived in pairs, while only around 15 percent of individuals were solitary.
Published Magnetic fields in the cosmos: Dark matter could help us discover their origin
(via sciencedaily.com)
Original source 
We don't know how magnetic fields in the cosmos formed. Now a new theoretical research tells how the invisible part of our universe could help us find out, suggesting a primordial genesis, even within a second of the Big Bang.
Published New reasons eating less fat should be one of your resolutions
(via sciencedaily.com)
Original source 
A new study to motivate your New Year's resolutions: it demonstrates that high-fat diets negatively impact genes linked not only to obesity, colon cancer and irritable bowels, but also to the immune system and brain function.
Published Potency of synthetic antibiotic against serious chronic infections
(via sciencedaily.com)
Original source 
A new synthetic antibiotic is shown to be more effective than established drugs against 'superbugs' such as MRSA, a new study shows.
Published Researchers boost signal amplification in perovskite nanosheets
(via sciencedaily.com)
