Imagine a world with precision medicine, where a swarm of microrobots delivers a payload of medicine directly to ailing cells. Or one where aerial or marine drones can collectively survey an area while exchanging minimal information about their location.
One early step towards realizing such technologies is being able to simultaneously simulate swarming behaviors and synchronized timing—behaviors found in slime molds, sperm and fireflies, for example.
In 2014, Cornell researchers first introduced a simple model of swarmalators—short for “swarming oscillator”—where particles self-organize to synchronize in both time and space. In the study, “Diverse Behaviors in Non-uniform Chiral and Non-chiral Swarmalators,” which published Feb. 20 in the journal Nature Communications, they expanded this model to make it more useful for engineering microrobots; to better understand existing, observed biological behaviors; and for theoreticians to experiment in this field.
One of the most concerning outcomes following surgery and anesthesia among older adults is a condition known as postoperative cognitive dysfunction (POCD). Often, patients and their family members report feeling very fearful that the patient will suffer permanent cognitive deficits after anesthesia. Unfortunately, this pre-emptive fear may contribute to the complex array of symptoms associated with POCD and further complicate the ability to fully understand the subjective experience of this postoperative complication.
About the study
The current study published in the British Journal of Anesthesia involved the collection of data from the comments section of the published article titled ‘The hidden long-term risks of surgery.’ The comments were given an alphanumeric code to maintain chronological order and structure, while the username, submission date, and time were kept anonymous.

After six bloody years of conflict the Soviets call for an urgent conference and UN Major Joseph Hendricks sets out to meet them. Along the way he will discover what the Claws have been up to, and it isn’t good… — Second Variety was first published in the May 1953 edition of Space Science Fiction Magazine.

About the Author, Philip K. Dick: Philip Kindred Dick (December 16, 1928 – March 2, 1982) was an American writer notable for publishing works of science fiction. Dick explored philosophical, social, and political themes in novels with plots dominated by monopolistic corporations, authoritarian governments, alternate universes, and altered states of consciousness. His work reflected his personal interest in metaphysics and theology, and often drew upon his life experiences in addressing the nature of reality, identity, drug abuse, schizophrenia, and transcendental experiences.
Born in Illinois before moving to California, Dick began publishing science fiction stories in the 1950s, initially finding little commercial success. His 1962 alternate history novel The Man in the High Castle earned Dick early acclaim, including a Hugo Award for Best Novel. He followed with science fiction novels such as Do Androids Dream of Electric Sheep? (1968) and Ubik (1969). His 1974 novel Flow My Tears, the Policeman Said won the John W. Campbell Memorial Award for best novel. Following a series of religious experiences in February–March 1974, Dick’s work engaged more explicitly with issues of theology, philosophy, and the nature of reality, as in such novels as A Scanner Darkly (1977) and VALIS (1981). A collection of his non-fiction writing on these themes was published posthumously as The Exegesis of Philip K. Dick (2011). He died in 1982 of a stroke, aged 53.
In addition to 44 published novels, Dick wrote approximately 121 short stories, most of which appeared in science fiction magazines during his lifetime. A variety of popular films based on his works have been produced, including Blade Runner (1982), Total Recall (1990), Minority Report (2002), A Scanner Darkly (2006), Paycheck (2003), Next (2007), and The Adjustment Bureau (2011). In 2005, Time magazine named Ubik one of the hundred greatest English-language novels published since 1923. [6] In 2007, Dick became the first science fiction writer to be included in The Library of America series.

Summary: The human brain continues to massively outperform AI technology in a range of tasks, a new study reports. Researchers outline their plans for biocomputers and organoid intelligence systems as future improvements for artificial intelligence technology.

The time has come to create a new kind of computer, say researchers from John Hopkins University together with Dr Brett Kagan, chief scientist at Cortical Labs in Melbourne, who recently led development of the DishBrain project, in which human cells in a petri dish learnt to play Pong.
Ford Motor Co. has filed for a patent on technology that could remotely shut down your radio or air conditioning, lock you out of your vehicle, or prompt it to ceaselessly beep if you miss car payments. Ford said it has no plans to use the technology, contained in just one of the many patents filed by the auto-making giant.
Still, it emerges at a troubling time for car owners. Loan delinquencies have been steadily ticking back up from their pandemic lull. Cox Automotive data showed severely delinquent auto loans in January hitting their highest point since 2006. The use of technology to aid repossessions isn’t new, but the patent application is wide-ranging, even proposing the idea that an autonomous vehicle could drive itself to a “more convenient” location to be collected by a tow truck.
“It really seems like you’re opening up a can of worms that, as a manufacturer, you don’t really need to be doing,” said John Van Alst, a senior attorney with the National Consumer Law Center.
It can even detect smells given off by people afflicted with a wide range of medical conditions, such as asthma and kidney disease, according to a press release by the institution published Wednesday.
Despite AI’s impressive track record, its computational power pales in comparison with that of the human brain. Scientists today unveil a revolutionary path to drive computing forward: organoid intelligence (OI), where lab-grown brain organoids serve as biological hardware. “This new field of biocomputing promises unprecedented advances in computing speed, processing power, data efficiency, and storage capabilities – all with lower energy needs,” say the authors in an article published in Frontiers in Science.
Artificial intelligence (AI) has long been inspired by the human brain. This approach proved highly successful: AI boasts impressive achievements – from diagnosing medical conditions to composing poetry. Still, the original model continues to outperform machines in many ways. This is why, for example, we can ‘prove our humanity’ with trivial image tests online. What if instead of trying to make AI more brain-like, we went straight to the source?
Scientists across multiple disciplines are working to create revolutionary biocomputers where three-dimensional cultures of brain cells, called brain organoids, serve as biological hardware. They describe their roadmap for realizing this vision in the journal Frontiers in Science.
Scientists from Denmark and China have estimated germline mutation rates across vertebrates by sequencing and comparing genetic samples from 151 mother, father, and offspring trios from 68 species of mammals, fishes, birds and reptiles. A bioinformatics pipeline was designed to read, analyze and compare the genome mutations that occur yearly and between generations in each species.
The research was published March 1, 2023, in the journal Nature.
Knowing the germline mutation rate could allow a greater understanding of evolutionary drivers and be used to estimate when a species first arose. Despite the variety of evolutionary paths seen in 68 different species, researchers found the germline mutation rate to be relatively conserved.
