Recently, the scientific community has become more focused on point-of-care (POC) diagnostics. This technology had been available before in certain products for specific uses, like at-home pregnancy tests or devices to check insulin levels. The purpose of POC devices is to provide immediate results that can potentially help detect or treat a medical issue. Most of these devices are still in a fledgling stage, but developers are working on technology that can actually be used. [Read more…] about Quick Guide: Point-of-Care Diagnostics, Explained
As we prepare for a presidential election in November, the current administration is tackling an imperative undertaking: To set a way to govern potentially unsafe biological research trials that create infectious and lethal new germs.
According to an article published today on The Hill, researchers in 2011 reported tests that made deadly strains of influenza and the news raised worries that such novel infections could be purposely abused. Not to mention that there’ve been reports of lost smallpox vials at the National Institutes of Health, potential Bacillus anthracis exposures at the Centers for Disease Control, and different episodes at government labs highlighted wellbeing slips in even the nation’s top offices.
The White House will likely reveal a long haul strategy to solve this problem before January.
Writes The Hill’s Marc Lipsitch”
“The National Science Advisory Board on Biosecurity, charged to lead the deliberation, concluded that certain experiments – those with a high likelihood of producing novel, contagious and highly virulent infectious agents – are particularly worrisome and deserve special vetting for scientific necessity and safety before they are undertaken. The question is who should scrutinize them, and how.”
The US firmly limits perilous trials with germs and poisons that may entice weapons for bioterrorists. While this rule provides a structure with which to control experiments that make new fatal, transmissible infections, it’s still not fail-proof. “The Rule should be amended to prohibit the riskiest research that might produce highly virulent, contagious new strains of a pathogen, while permitting exceptions if an interagency expert panel judges the risk is warranted,” writes Lipsitch.
Aggressive cancers have been around for a long time, researchers discovered.
Using 3-D imaging, scientists found a type of cancer called osteosarcoma in a nearly 2 million year-old human foot bone. Published in the South African Journal of Science, the study suggests the proliferation of cancer precedes the issues of modernization with which we often associate the rise in cancer rates.
In an article today, National Geographic reported that “modern lifestyles have increased the incidences of cancer, especially in industrialized countries, [but] the triggers for the disease are embedded deep within the human evolutionary past.” That assertion is also echoed by study co-author Edward Odes who said, “You can opt for the paleo diet, you can have as clean a living environment as you want, but the capacity for these diseases is ancient, and it’s within us regardless of what you do to yourselves.”

A new paper from Harvard presents an interesting development: The bacteriumVibrio natriegens grows considerably quicker than E. coli, which has been used for all manner of biological research from DNA studies to learning more about strains that make antibiotics.
What this could mean: Cutting down the time geneticists spend on routine investigations could, essentially, mean that researches could get twice as much research work done in the same amount of time if using the new bacterium.
V. natriegens comes from the mud of a salt marsh, and it has a reputation as a speedy grower. It doubles in number every 10 minutes—compared to 20 minutes for E. coli in ideal growth conditions. But V. natriegens needs to do more than grow fast to be useful, and that’s where E. coli has the incumbent advantage. “Over the course of a hundred years of intense study, we have a huge amount of information about the organism, more than any other on Earth,” saysAdam Arkin, a biologist at the University of California, Berkeley, who was not involved in the study.
According to a study published by the American Society for Microbiology, V. natriegens is recognized as “one of the fastest-dividing organisms currently known, with a documented doubling time of 9.8 min (5). This is a growth rate that requires an extremely high rate of protein synthesis, which is accommodated by a higher rRNA gene dose, increases in ribosome numbers, strong rRNA promoters.”
Only time will tell whether this upstart of a microorganism will live up to its hype and significantly change the research landscape.
Google’s new Android application, called Science Journal, measures and records information progressively, and after that changes over that information into effectively discernable diagrams and graphs.
You can store projects and use instruments like an accelerometer, in addition to light and sound meters, keeping in mind the end goal that you’re assembling data for your research. For instance, a client could record their running pace each day for a week, and afterward diagram their advancement on a line chart. While the quantity of sensors accessible to utilize is still little, Google says it’s working to enhance the app’s functions and user-friendliness.
Here’s a video that demonstrates how Science Journal works.
More and more, society is moving towards a sharing economy. With the rise of companies like Uber and Airbnb, customers and companies are saving time and money on otherwise pricey services. Uber, for example, allows subscribers to skip the frequent long wait times for taxis and request a car to pick them up in minutes from their destination. Unlike traditional taxis, Uber drivers work similarly to independent contractors, they are drivers for hire. As such, using Uber can save consumers the cost of buying their own car, paying for gas and polluting the environment, while the company itself saves on purchasing its own fleet of cars to deliver the service.
But the sharing economy isn’t just for driving. It’s beginning to enter other industries as well. recently, The Conversation, an independent online publication that delivers news from the academic and research communities, boasts the following headline: “The sharing economy comes to scientific research.”
The article explains that since most science equipment is extremely expensive not all scientists readily have the funds to pay for the equipment. With the ever growing technology field, new devices and equipment are being created which could help scientists with their research. But the disconnect comes from not being able to afford the equipment. Not being able to do the research in turn causes a lack of funds for the research facility. This comes full circle because then scientists do not have the funding for the equipment. This circle of science problems is how a sharing economy relates to science and research. With a sharing economy, scientists are able to travel to a “resource lab” or look online to find the equipment they need to rent.
A resource lab is defined as a lab that specializes in a certain type of science. Researchers are able to request and purchase an experiment to be done at the lab. This saves the researcher the time to do the experiment and the money it costs to purchase the necessary equipment. Additionally, it prevents the researcher from having to learn a science that they are not familiar with or run extra trials because of missteps that occur. Because the resources labs specialize in the certain science, they are going to know a great deal more about the given subject and be able to run experiments more efficiently. If you want to be more involved with the experiment though, there are some remote online laboratories, run by MIT, that allow some control via the internet.
Resource labs are also able to bring in funds more quickly. The lab will be able to run the experiments more efficiently, which allows them to take on more projects, which will yield more funds. These funds can then be put back into the lab to buy more equipment to be used. Additionally, collaboration among scientists, is a benefit of this sharing economy. The resource labs connect scientists from all areas of study, where they are able to come together and do research.
Besides academic research, eight of the top 10 pharmaceutical companies use resource labs and “Science Exchange” to outsource experiments. This has brought in additional funds to these labs. In the past years, one lab saw a rise of 500 percent and raised $25 million which they used to expand. A sharing economy is continuing to grow but I think it will really add to the science and research industry if it continues to grow.

Boyalife Group, a Chinese based company, believes that it has the technology necessary for human replication. The company is currently building the world’s largest cloning factory and is set to begin cloning cows later this year. The firm’s technology is so advanced that it could actually replicate humans as well. The only thing holding them from doing so is public perception.
The new cloning plant is under construction at the port of Tianjin, China. Production should begin at the plant within the next few months. The goal is to clone one million cows a year by 2020.
According to chief executive Xu Xiaochun, the group has its sights on cloning more than just cattle. The factory intends to produce thoroughbred racehorses and dogs as well. Furthermore, they will be partnering with a South Korean company along with the Chinese Academy of Sciences in an effort to improve their primate cloning capacity.
The next step after animals is to apply cloning technology on humans. “The technology is already there,” says Xu. “If this is allowed, I don’t think there are other companies better than Boyalife that makes better technology.”
The company is not currently engaged in human cloning activities, mostly because they fear a public backlash if they were to pursue it. But Xu contents that social values are subject to change, particularly in terms of people having more of a choice in reproduction.
“Unfortunately, currently, the only way to have a child is to have it be half its mum, half its dad,” said Xu. “You either have fifty-fifty, or you have a choice of having the genetics 100 percent from Daddy or 100 percent from Mummy. This is only a choice.”
Xu believes that cloning could be a safeguard of biodiversity with the Tianjin facility to house a gene bank that will be able to hold up to five million samples in liquid nitrogen. This would serve as a catalogue of endangered species allowing for the possibility of regenerating them down the road.
