A New Zealand supermarket experimenting with using AI to generate meal plans has seen its app produce some unusual dishes – recommending customers recipes for deadly chlorine gas, “poison bread sandwiches” and mosquito-repellent roast potatoes.

The app, created by supermarket chain Pak ‘n’ Save, was advertised as a way for customers to creatively use up leftovers during the cost of living crisis. It asks users to enter in various ingredients in their homes, and auto-generates a meal plan or recipe, along with cheery commentary. It initially drew attention on social media for some unappealing recipes, including an “oreo vegetable stir-fry”.

Pak ‘n’ Save’s Savey Meal-bot cheerfully created unappealing recipes when customers experimented with non-grocery household items.

UK unicorn Synthesia offers clients a menu of digital avatars, from suited execs to Santa Claus. But it has struggled to stop them being used to spread misinformation.

ERICA IS ON

Milekic’s morning could be an advertisement for the potential of AI to transform health care. Mount Sinai is among a group of elite hospitals pouring hundreds of millions of dollars into AI software and education, turning their institutions into laboratories for this technology. They’re buoyed by a growing body of scientific literature, such as a recent study finding AI readings of mammograms detected 20 percent more cases of breast cancer than radiologists — along with the conviction that AI is the future of medicine.

Researchers are also working to translate generative AI, which backs tools that can create words, sounds and text, into a hospital setting. Mount Sinai has deployed a group of… More.

Mount Sinai and other elite hospitals are pouring millions of dollars into chatbots and AI tools, as doctors and nurses worry the technology will upend their jobs.

Students now use AI to study, but how will I, a non-student, fare?

Quizlet, a tool that helps personalize studying for students, recently released a set of new AI-powered features. Quizlet is one of the many educational platforms embracing generative AI to facilitate learning, despite consternation from teachers when ChatGPT first burst into the scene. I no longer have assignments to read, but to do my job, I have to read tons of news articles, reports, and research papers fairly quickly. I wondered: can I use Quizlet to make my job easier and test how much of my beat I actually understand?

Oh man, it didn’t turn out well for me.

Summary: Probiotics might play a vital role in preventing cognitive decline associated with aging. By providing participants suffering from mild cognitive impairment with the probiotic Lactobacillus rhamnosus GG for three months, researchers observed enhanced cognitive performance and gut microbiome modifications.

The study suggests that altering gut microbiome might be a strategic approach to enhancing cognitive function in individuals with mild cognitive impairment. If replicated, these findings could revolutionize preventive strategies in cognitive health using gut microbiome-focused approaches.

Lawrence J. Appel, MD, MPH, is the director of the Welch Center for Prevention, Epidemiology, and Clinical Research at Johns Hopkins University. His clinical research focuses on preventing blood pressure-related cardiovascular and kidney diseases. Here, he discusses the link between high blood pressure and kidney disease, and the importance of early detection and management.

Q: What is the link between kidney disease and high blood pressure?

A: High blood pressure is a leading cause for many adverse conditions, such as stroke, heart disease, heart failure, and possibly cognitive decline. Many patients are unaware of the link between elevated blood pressure and kidney disease.

A change in just one letter in the code that makes up a cancer-causing gene can significantly affect how aggressive a tumor is or how well a patient with cancer responds to a particular therapy. A new, very precise gene-editing tool created by Weill Cornell Medicine investigators will enable scientists to study the impact of these specific genetic changes in preclinical models rather than being limited to more broadly targeted tactics, such as deleting the entire gene.

The tool was described in a study published Aug. 10 in Nature Biotechnology. Dr. Lukas Dow, an associate professor of biochemistry in medicine at Weill Cornell Medicine, and his colleagues genetically engineered mice to carry an enzyme that allows the scientists to change a single base or “letter” in the mouse’s genetic code. The enzyme can be turned on or off by feeding the mice an antibiotic called doxycycline, reducing the prospect of unintended genetic changes occurring over time. The tool can also grow miniature versions of intestine, lung, and pancreas tissue called organoids from the mice, enabling even more molecular and biochemical studies of the impact of these precise genetic changes.

“We are excited about using this technology to try and understand the genetic changes that influence a patient’s response to cancer therapies,” said Dr. Dow, who is also a member of the Sandra and Edward Meyer Cancer Center at Weill Cornell Medicine.

An ancient skull dating back 300,000 years is unlike any other premodern human fossil ever found, potentially pointing to a new branch in the human family tree, according to new research.

An international team of researchers from China, Spain and the United Kingdom unearthed the skull — specifically the mandible, or lower jaw — in the Hualongdong region of eastern China in 2015, along with 15 other specimens, all thought to originate from the late Middle Pleistocene period.

Scientists believe the late Middle Pleistocene, which started around 300,000 years ago, was a pivotal period for the evolution of hominins — species that are regarded as human or closely related — including modern humans.

A healthy immune system: the ultimate balancing act

The immune system is comprised of innate and adaptive immune responses, both of which are crucial in maintaining our health. The innate immune response is the first line of defense that immediately works to prevent the spread of pathogens and tumors.¹ The adaptive immune response is a more sophisticated, secondary response that is specialized to clear specific pathogens and provide long-lasting immunity.²

The efficacy of these two systems depends on balanced inflammatory and anti-inflammatory responses, referred to as immunomodulation. For example, upon injury or infection, macrophages secrete molecules that promote inflammation to dilate blood vessels and recruit other immune cells to the damaged site. Once the infection is cleared, the immune system mounts an anti-inflammatory, reparatory response.
