As any weekend warrior understands, cartilage injuries to joints such as knees, shoulders, and hips can prove extremely painful and debilitating. In addition, conditions that cause cartilage degeneration, like arthritis and temporomandibular joint disorder (TMJ), affect 350 million people in the world and cost the U.S. public health system more than $303 billion every year. Patients suffering from these conditions experience increased pain and discomfort over time.

However, an exciting study led by faculty at The Forsyth Institute suggests new strategies for making cartilage cells with huge implications in regenerative medicine for future cartilage injuries and degeneration treatments. In a paper, entitled “GATA3 mediates nonclassical β-catenin signaling in skeletal cell fate determination and ectopic chondrogenesis,” co-first authors Takamitsu Maruyama and Daigaku Hasegawa, and senior author Wei Hsu, describe two breakthrough discoveries, including a new understanding of a multifaced protein called β-catenin.

Dr. Hsu is a senior scientist at the Forsyth Insitute and a Professor of Developmental Biology at Harvard University. He is also an affiliate faculty member of the Harvard Stem Cell Institute. Other members conducting the study included Swiss scientists Tomas Valenta and Konrad Basler, and Canadian scientists Jody Haigh and Maxime Bouchard. The study appears in the most recent issue of Science Advances.

Malaria is found in more than 90 countries around the world, causing 241 million cases and an estimated 627,000 deaths every year. Vaccines are one intervention that could help eliminate this deadly disease, yet a highly effective vaccine remains elusive. Recent technological advances in vaccine development–such as the mRNA vaccines for SARS-CoV2–could lead to a new generation of malaria vaccines.

Now, a research team led by George Washington University has developed two mRNA vaccine candidates that are highly effective in reducing both malaria infection and transmission. The team also found that the two experimental vaccines induced a powerful immune response regardless of whether they were given individually or in combination. The study was published today in npj Vaccines, an open-access scientific journal that is part of the Nature Portfolio.

“Malaria elimination will not happen overnight but such vaccines could potentially banish malaria from many parts of the world,” Nirbhay Kumar, a professor of global health at the George Washington University Milken Institute School of Public Health, said. “The mRNA vaccine technology can really be a game changer. We saw how successful this technology was in terms of fighting COVID and for this study we adapted it and used it to develop tools to combat malaria.”

In our cells, the language of DNA is written, making each of us unique. A tandem repeat occurs in DNA when a pattern of one or more nucleotides—the basic structural unit of DNA coded in the base of chemicals cytosine ©, adenine (A), guanine (G) and thymine (T)—is repeated multiple times in tandem. An example might be: CAG CAG CAG, in which the pattern CAG is repeated three times.

Now, using state-of-the-art whole-genome sequencing and machine learning techniques, the UNC School of Medicine lab of Jin Szatkiewicz, Ph.D., associate professor of genetics, and colleagues conducted one of the first and the largest investigations of tandem repeats in schizophrenia, elucidating their contribution to the development of this devastating disease.

Published in the journal Molecular Psychiatry, the research shows that individuals with schizophrenia had a significantly higher rate of rare tandem repeats in their genomes—7% more than individuals without schizophrenia. And they observed that the tandem repeats were not randomly located throughout the genome; they were primarily found in genes crucial to brain function and known to be important in schizophrenia, according to previous studies.

Functional adrenal glands have been grown in the lab by coaxing a type of stem cell to develop in a certain way by constantly tweaking the mix of chemicals they are bathed in.

A team in Korea has used sound waves to connect tiny droplets of liquid metals inside a polymer casing. The novel technique is a way to make tough, highly conductive circuits that can be flexed and stretched to five times their original size.

Making stretchable electronics for skin-based sensors and implantable medical devices requires materials that can conduct electricity like metals but deform like rubber. Conventional metals don’t cut it for this use. To make elastic conductors, researchers have looked at conductive polymers and composites of metals and polymers. But these materials lose their conductivity after being stretched and released a few times.

Liquid metals, alloys that stay liquid at room temperature, are a more promising option. Gallium-based liquid metals, typically alloys of gallium and indium, have caught the most attention because of their low toxicity and high electrical and heat conductivity. They are also tough because of an oxide skin that forms on their surface, and they stick well to various substrates.

You can’t discuss fulfillment robots without mentioning Amazon. Over the past decade, the retail juggernaut has become the 800-pound gorilla in the category, courtesy of several key acquisitions and seemingly endless resources. And while warehouse robotics and automation have been accelerated amid the pandemic and resulting employment crunch, Amazon Robotics has been driving these categories for years now.

This week at its annual Re: Mars conference in Las Vegas, the company celebrated a decade of its robotics division, which was effectively born with its acquisition of Kiva Systems. Over the course of its life, Amazon Robotics has deployed more than 520,000 robotic drive units, across its fulfillment and sort centers. From the outside, it’s been a tremendous success in the company’s push toward same-and next-day package delivery, and its driven the competition to look for their own third-party robotics solutions, bolstering startups like Locus, Fetch and Berkshire Grey.

Using modified MRI machines, physicists may have found quantum entanglement between the heart and brain If someone were to (theoretically) throw a wrench at your head, you might be able to catch it just in time to avoid a concussion. But how? Typically, for split-second reactions, we do not consciously decide to catch.

Alzheimer’s disease could soon be a distant memory.

A revolutionary new Alzheimer’s drug named lecanemab could mark a major breakthrough in the decades-long battle against the neurological disorder, according to eye-opening Phase 3 trials. The potentially game-changing dry runs transpired in May 2021, but the results were only published Tuesday in the New England Journal of Medicine.

“This first step is the hardest; I truly believe it represents the beginning of the end,” said Professor John Hardy, group leader at UK Dementia Research Institute at the University College London, describing the promising findings.
