The SMART AMR research team designed an easily modifiable genetic technique that allows rapid and efficient silencing of bacteria genes to prevent infections.
In a paper published in the journal mBio, the researchers explain the scalable dual-vector nisin-inducible CRISPRi system, which can identify genes that allow bacteria like E. faecalis to form biofilms, cause infections, acquire antibiotic resistance, and evade the host immune system. The team combined CRISPRi technology with rapid DNA assembly under controllable promoters, which enables rapid silencing of single or multiple genes, to investigate nearly any aspect of enterococcal biology.
I began wondering what a behavioral science approach to romantic relationships might look like. There is no shortage of work on how to apply behavioral science to other aspects of our lives to improve our productivity, health, or financial well-being. Why not relationships?
The suprising science that will help you find love
Enter Logan Ury, behavioral scientist, dating coach, and director of relationship science at the dating app Hinge. Her new book, How to Not Die Alone: The Surprising Science that Will Help You Find Love, is a data-driven guide to relationships, filled with exercises and tools to help you detect your behavioral biases and nudge yourself to better relationships. Combining everything behavioral science has to offer with her own experience from coaching clients, she provides answers to many of the questions my friends and I so often discussed.
I recently had the chance to sit down with Logan over Zoom.
A team of researchers at New York University will develop new methods and tools aimed at minimizing systemic biases and producing more equitable public policy impacts on such areas as city housing inspections, policing, and courts.
Under a $1 million grant from the National Science Foundation (NSF) and Amazon, Computer Science Professor Daniel B. Neill will lead the three-year research project centered on the growing use of Artificial Intelligence (AI) by urban public sector organizations—work that will include the creation of open source tools for assessing and correcting biases.
Swarthmore College has been rated the best liberal arts college in the U.S. by Academic Influence, a new college rankings method that uses artificial intelligence technology to search massive databases and measure the impact of work by individuals who’ve been affiliated with colleges and universities throughout the world.
Last Monday, Academic Influence released its first-ever ranking of American liberal arts colleges – those four-year institutions that are relatively small in size, focus on bachelor’s level education, emphasize direct engagement with professors, provide an enriched residential experience, and insist on broad grounding in the liberal arts along with focused study in a major.
In brief, here’s how Academic Influence’s methodology works: It begins with the premise that the people affiliated with a school determine its quality. To measure that quality for undergraduates, a trademarked measure termed “Concentrated Influence” is computed.
Virginia is poised to follow in California’s footsteps any minute now and become the second state in the country to adopt a comprehensive online data protection law for consumers.
If adopted, the Consumer Data Protection Act would apply to entities of a certain size that do business in Virginia or have users based in Virginia. The bill enjoys broad popular support among state lawmakers; it passed 89-9 in the Virginia House and unanimously (39-0) in the state Senate, and Democratic Gov. Ralph Northam is widely expected to sign it into law without issue in the coming days.
Until recently, genetic research in Africa was scanty, and most was done by researchers swooping in from afar to gather samples, then leaving to do analyses in well-equipped labs in the United States or Europe. “African genomic study was characterized by ethical dumping, helicopter science, and exploitation,” [Segun] Fatumo says. Researchers gathered samples with little regard for informed consent and without giving back to the communities they studied, he says.
Today, Fatumo and scores of other young Africans are doing a substantial and growing share of this research. “African genomics is a story that’s going to be told more and more by Africans,” says Charles Rotimi, a genetic epidemiologist at the U.S. National Human Genome Research Institute (NHGRI).
Bolstered by the internationally funded Human Heredity & Health in Africa (H3Africa) Initiative, which sponsored Fatumo as a postdoc, these researchers hope to one day use their data to bring genetically tailored medicine to people who in some places still struggle to get electricity and basic health care.
A machine-learning technique first developed for understanding language can accurately classify reactions according to type (Nat. Mach. Intell. 2021, DOI: 10.1038/s42256-020-00284-w). The model also tagged reactions with computer-readable codes that allow chemists to search for similar reactions.
Transformers are a type of machine-learning algorithm useful for interpreting sequences of information. They’re widely used in translation software and voice assistants like Amazon’s Alexa, but chemists recently have shown their utility in chemistry (see page 19). Philippe Schwaller of IBM Research–Zurich and the University of Bern and colleagues show the transformer approach can classify reactions by type, identifying broad categories like carbon-carbon bond formation or deprotection and finer-scale groups like chloro or bromo Suzuki coupling. When categorizing reactions, the machine-learning model matched the classifications assigned by software that used human-coded rules 98% of the time.

A new partnership of UC Santa Barbara’s Institute for Energy Efficiency (IEE)(link is external) and Facebook will accelerate research into energy-efficient data centers and artificial intelligence (AI). Facebook, a leader in developing, building and operating highly reliable and efficient data centers, will provide a three-year, $1.5 million grant in support of the institute’s pioneering research.
Through this partnership, IEE will investigate advanced energy-efficient data center infrastructure, including low-power optical interconnects for computer networks and machine learning (ML) with reduced carbon footprint.
NOAA and The University of Southern Mississippi (USM) signed a 10-year agreement today to collaborate on ways to improve how uncrewed systems (UxS) are used to collect important ocean observation data and augment NOAA’s operational capabilities. The agreement provides a framework for collaborating with NOAA scientists and UxS operators on projects to further UxS research, development and operations.
Rear Adm. Nancy Hann“Mississippi is poised to become a major hub for ocean research and innovation, and NOAA plans to help drive that innovation,” said Rear Adm. Nancy Hann, deputy director for operations for NOAA’s Office of Marine and Aviation Operations (OMAO) and deputy director of the NOAA Commissioned Officer Corps. “This new partnership with the University of Southern Mississippi will greatly enhance our ability to transition these technologies into operational platforms that will gather critical environmental data for the nation.”
You might soon be able to use an AI system to help train your dog to sit. A pair of researchers from Colorado State University have developed an artificial intelligence system that detects when a dog is sitting, standing or lying. If your furry friend takes up the right position upon your command, the system will reward your pooch by automatically dispensing a treat via a servo motor.
Jason Stock and Tom Cavey, who are computer science grad students, used NVIDIA’s Jetson edge AI to create the system. They trained it using more than 20,000 labeled images of dogs in various positions.
The explosion of data led governments, funding agencies, research institutes and private research consortia to develop their own custom-built databases for handling the complex and sometimes sensitive data sets. And the patchwork of repositories, with various rules for access and no standard data formatting, has led to a “Tower of Babel” situation, says [David] Haussler.
Although some researchers are reluctant to share genome data, the field is generally viewed as generous compared with other disciplines. Still, the repositories meant to foster sharing often present barriers to those uploading and downloading data. Researchers tell tales of spending months or years tracking down data sets, only to find dead ends or unusable files. And journal editors and funding agencies struggle to monitor whether scientists are sticking to their agreements.
Many scientists are pushing for change, but it can’t come fast enough.

When searching for the animal — or animals — involved in zoonotic diseases, Dr [Hume] Field said there’s no general playbook to follow.
Instead, it’s a matter of starting with whatever information you can find, which is usually the time and place of an event such as the first known human case, and try to trace forwards and backwards from that point.
To determine the human seasons, [Michael] Snyder’s team profiled the biology of 105 volunteers in the San Francisco Bay area over a period of four years. They regularly sampled and measured tens of thousands of molecules and microbes from the participants’ blood, noses and guts. This type of study is called ‘deep longitudinal multiomics profiling’.
On sample days, the researchers also collected meteorological data (such as air temperature and solar radiation) and airborne pollen counts.
This massive effort was undertaken to create a better picture of how the changing seasons might be affecting our physiology and health.
Accepted for publication in the Journal of Medical Internet Research, the institution’s Warrior Watch Study provided Mount Sinai Health System workers with an Apple Watch and a custom study app. The results highlight a significant differences in a heart rate variability (HRV) metric during the seven days before a PCR COVID-19 diagnosis and the seven days after.
“[This study] shows that we can use these technologies to better address evolving health needs, which will hopefully help us improve the management of disease,” Dr. Robert P. Hirten, assistant professor of medicine at the Icahn School of Medicine at Mount Sinai
