Food tech startup Farther Farms has developed a process that keeps foods that would normally need to be refrigerated or frozen fresh at room temperature — and their first product is a bag of shelf-stable French fries.
The cold chain: Microorganisms are a major cause of food spoilage, and they thrive at room temperature. By keeping some foods cold, we can slow the growth of these microbes, extending the life of the food.
To do that, the foods must be prepared, shipped, and stored along a temperature-controlled supply chain (a “cold chain”). If the cold chain is broken at any point along the way, the food may quickly become unsafe to eat.
Using AI, Ting Xu and her colleagues designed polymer mixtures that mimic the natural proteins in biological fluids. The technique could improve the design of biocompatible materials.
In 1997, IBM’s Deep Blue defeated the reigning world champion chess player, Garry Kasparov. In 2016, Google’s AlphaGo defeated one of the worlds top Go players in a five-game match. Today, OpenAI released GPT-4, which it claims beats 90% of humans who take the bar to become a lawyer, and 99% of students who compete in the Biology Olympiad, an international competition that tests the knowledge and skills of high school students in the field of biology.
In fact, it scores in the top ranks for at least 34 different tests of ability in fields as diverse as macroeconomics, writing, math, and — yes — vinology.
“GPT-4 exhibits human-level performance on the majority of these professional and academic exams,” says OpenAI.
Studying Our Ocean’s History To Understanding Its Future — Dr. Emily Osborne, PhD, Ocean Chemistry & Ecosystems Division, National Oceanic and Atmospheric Administration (NOAA)
Dr Emily Osborne, Ph.D. (https://www.aoml.noaa.gov/people/emily-osborne/) is a Research Scientist, in the Ocean Chemistry and Ecosystems Division, at the Atlantic Oceanographic and Meteorological Laboratory.
The Atlantic Oceanographic and Meteorological Laboratory (AOML), a federal research laboratory, is part of the National Oceanic and Atmospheric Administration’s (NOAA) Office of Oceanic and Atmospheric Research (OAR), located in Miami in the United States. AOML’s research spans tropical cyclone and hurricanes, coastal ecosystems, oceans and human health, climate studies, global carbon systems, and ocean observations. It is one of ten NOAA Research Laboratories.
With a B.S. in Geology from the College of Charleston and a Ph.D. in Marine Science from University of South Carolina, Dr. Osborne is currently involved in investigating regional and global biogeochemical issues related to ocean health and climate through the use of a combination of paleoceanographic approaches, new autonomous sensors, and conventional measurements on large multi-disciplinary oceanographic cruises.
Paleoceanography is the study of the history of the oceans in the geologic past with regard to circulation, chemistry, biology, geology and patterns of sedimentation and biological productivity. Paleoceanographic studies using environment models and different proxies enable the scientific community to assess the role of the oceanic processes in the global climate by the re-construction of past climate at various intervals.
A biological method that produces metal nanoclusters using the electroactive bacterium Geobacter sulfurreducens could provide a cheap and sustainable solution to high-performance catalyst synthesis for various applications such as water splitting.
Metal nanoclusters contain fewer than one hundred atoms and are much smaller than nanoparticles. They have unique electronic properties but also feature numerous active sites available for catalysis on their surface. There are several synthetic methods for making metal nanoclusters, but most require multiple steps involving toxic substances and harsh temperature and pressure conditions.
Biological methods are expected to deliver ecofriendly alternatives to conventional chemical synthesis. Yet, to date, they have only led to large nanoparticles in a wide range of sizes. “We found a way to control the size of the nanoclusters,” says Rodrigo Jimenez-Sandoval, a Ph.D. candidate in Pascal Saikaly’s group at KAUST.
There’s a lot of articles written about how tap water in Warsaw is constantly tested by a small team of clams. It felt like a hoax to me: so I went to find out. ▪ Thanks to MPWiK Warsaw: https://www.mpwik.com.pl/
We had a wonderful group of international and interdisciplinary speakers at Saint Mary’s University on March 31 to April 1, 2017. They all took time out from their very busy schedules to come to Halifax to discuss robots and artificial intelligence at the Cyborg Futures Workshop. Academics from literary theory, digital culture, anthropology, sociology, environmental studies, robotics, and evolutionary biology, along with students and the public, convened for a lively discussion about technologies that are impacting us all.
This workshop is part of a larger SSHRC-funded project–Where Science Meets Fiction: Social Robots and the Ethical Imagination–that is about shifting the conversation about robots and AI, which has been animated by fiction but dominated in the real world by the military and industry. Opening the discussion up to wider social and cultural contexts–from the impact of technology on human relations; to non-human animals, the environment and trash; to racism, imperialism and misogyny; to automation, labour and capitalism; to killer robots and the military; to the problematic collapse of science and fiction—this workshop considered both the infrastructure currently being laid that is forcing us down a troubling path and imaginative alternatives to it. What follows cannot possibly do justice to the richness and complexity of the talks, so please click on the hyperlinks to listen to them.
Social insects like bees demonstrate a remarkable range of behaviors, from working together to build structurally complex nests (complete with built-in climate control) to the pragmatic division of labor within their communities. Biologists have traditionally viewed these behaviors as pre-programmed responses that evolved over generations in response to external factors. But two papers last week reported results indicating that social learning might also play a role.
The first, published in the journal PLoS Biology, demonstrated that bumblebees could learn to solve simple puzzles by watching more experienced peers. The second, published in the journal Science, reported evidence for similar social learning in how honeybees learn to perform their trademark “waggle dance” to tell other bees in their colony where to find food or other resources. Taken together, both studies add to a growing body of evidence of a kind of “culture” among social insects like bees.
“Culture can be broadly defined as behaviors that are acquired through social learning and are maintained in a population over time, and essentially serves as a ‘second form of inheritance,’ but most studies have been conducted on species with relatively large brains: primates, cetaceans, and passerine birds,” said co-author Alice Bridges, a graduate student at Queen Mary University of London who works in the lab of co-author Lars Chittka. “I wanted to study bumblebees in particular because they are perfect models for social learning experiments. They have previously been shown to be able to learn really complex, novel, non-natural behaviors such as string-pulling both individually and socially.”
Progress in biomimetics allows for the fabrication of man-made materials and surfaces with properties similar to biological ones. These advancements enable the development of a new generation of building materials for architecture that have remarkable properties typically unachievable with a traditional approach.
Scientists have created eggs using the cells of male mice for the first time, leading to the birth of seven mice with two fathers, according to research Wednesday hailed as “revolutionary”.
The technique pioneered in the proof-of-concept experiment is a long way from potentially being used in humans, with obstacles including a low success rate, adaptation concerns and wide-ranging ethical considerations.
But the breakthrough raises the prospect of a raft of new reproductive possibilities, including that gay male couples —or even a single man—could have a biological child without needing a female egg.
