Ferroelectric modulation of Fermi level of graphene oxide to enhance SERS response

Surface-enhanced Raman scattering (SERS) is a powerful fingerprint analysis and detection technique that plays an important role in the fields of food safety, environmental protection, bio-imaging and hazardous substance identification. Electromagnetic enhancement (EM) and chemical enhancement (CM) are the two recognized mechanisms of action for amplifying Raman signals.

EM originates from the localized surface plasmonic resonance effect of noble metal nanostructures such as gold, silver, and copper, while CM originates from the charge transfer between the substrate and the probe molecules. In principle, the charge transfer efficiency depends on the coupling of the incident laser energy to the energy levels of the substrate-molecule system.

Compared to EM-based SERS substrates, CM-based SERS substrates are usually made of including semiconductor oxides, metal carbides, and graphene and its evolutions, which have weaker signal enhancement capabilities. However, the advantages of CM-based SERS substrate, such as high specificity, homogeneity and biocompatibility, have attracted the attention of researchers.

The First-Ever Lunar Farm Shows That Plants Can Grow On The Moon

Plants are not just able to survive in low gravity such as on the Moon, two new papers suggest – they may prefer it, at least based on the only species to sprout.

When Chang’e 4 landed on the Moon in January 2019 it carried with it a payload that could dictate the future of space exploration: seeds of four plant species it sought to grow on the lunar surface. The germination of a single cotton seed attracted plenty of attention at the time, but there’s more to growth than just sprouting. If crops grown on the Moon are less productive or more fragile than those on Earth, it’s going to be a big problem.

It’s taken more than four years, but important results from the experiment have now been released and they suggest that for all the obstacles to establishing colonies on the Moon and Mars, growing food might not be one. Then again, it’s still very early days.

Indian start-up develops autonomous cotton picker

Indian start-up Green Robot Machinery (GRoboMac) has developed a cotton picker with autonomous robotic arms, mounted on a semi-autonomous electric farm vehicle.

The robotic arms of the battery-operated machine are each capable of picking about 50 kgs cotton per day. That means that four arms, mounted on the vehicle, can pick about 200 kgs per day. High yielding farms can use additional arms, the company says.

AI Can Screen for Diabetes

In America, roughly 40 million Americans have diabetes and about 95% of them have type 2 diabetes. Type 2 diabetes occurs when the body cannot correctly process sugar and fuel cells. More specifically, the body does not produce enough insulin to break down sugar into glucose for the cells to use. In this case, treatment includes insulin shots or a pump in addition to a strict diet excluding sweets or high fat meals. Treatment limitations disrupt patient quality of life. Some researchers have been working on better detection for diabetic retinopathy with artificial intelligence (AI), but research is limited on how to better detect diabetes itself. Thus, many researchers are working to detect diabetes early on and discover better treatments.

Klick labs, located in multiple cities across the world, is trying to detect type 2 diabetes by having a patient speak into a microphone for 10 seconds. Klick labs believes this technology can better detect diabetes and help patients get treatment earlier. The study was published in Mayo Clinic Proceedings: Digital Health, which details how patients spoke for 10 seconds and combined with health data, including age, sex, height, and weight, created an AI model that discerns whether a person has type 2 diabetes or not. After further tests, scientists determined it has 89% and 86% accuracy for women and men, respectively.

In the study, Klick Labs collected voice recordings of 267 people, either non-diabetic or diabetic. The participants were asked to record a phrase into their smartphones six times a day for a total of 2-weeks. Over 18,000 recordings were taken and analyzed to distinguish 14 acoustic features that helped distinguish non-diabetic to type 2 diabetic individuals. The research highlights specific vocal variations in pitch and intensity that could lead to how the medical community screens for early-onset diabetes. A major barrier to early detection includes time, travel, and cost, which many people do not have. Voice diagnosis can help eliminate those barriers and improve detection and treatment in diabetic patients.

New software tool provides a way for safer design of genome editing

A team of researchers has developed a software tool called DANGER (Deleterious and ANticipatable Guides Evaluated by RNA-sequencing) analysis that provides a way for the safer design of genome editing in all organisms with a transcriptome. For about a decade, researchers have used the CRISPR technology for genome editing. However, there are some challenges in the use of CRISPR. The DANGER analysis overcomes these challenges and allows researchers to perform safer on-and off-target assessments without a reference genome. It holds the potential for applications in medicine, agriculture, and biological research.

Their work is published in the journal Bioinformatics Advances on August 23, 2023.

Genome editing, or gene editing, refers to technologies that allow researchers to change the genomic DNA of an organism. With these technologies, researchers can add, remove or alter genetic material in the genome.

A Scoring System That Links Gut Microbiome Interactions & Disease

The human gut microbiome has a crucial connection to our health and well-being, but it is a complex entity made up of many different organisms, which all have an effect on one another. The hundreds of different microbial species in the gut metabolize the foods we consume in different ways, and the metabolites that microbes generate are often then consumed by other microbes. It’s been suggested that the more than half of the stuff that is eaten by gut microbes are byproducts of other gut microbes. This interdependence can have profound implications for the gut microbiome, and some species become totally reliant on the presence of others.

Scientists are still learning about the various characteristics of a healthy human gut microbiome, but there are certain species that tend to be present. High diversity in the microbiome is also typically associated with good health. While some microbes can fill in the gaps if other important ones are missing, some species can’t be substituted.

Newly Found Pandoraviruses Hint at a Fourth Branch of Life

This exemplary virus makes its own genes which many have theories say that it could be a direct relationship to the sorta alien ant farm we are currently in on earth. That maybe it is a clue that viruses started all life from a sorta panspermia whether it was from meteorites or even direct gene engineering from aliens this virus gives us a clue even to our evolutionary processes that we could even become aliens someday.

Pandoraviruses, the largest viruses ever found, are shaking up the tree of life. Could they and other abnormally large viruses belong to a fourth branch of life separate from Bacteria, Archaea, and Eukaryotes?
