“The definition of the human embryo is far from being engrained, it’s constantly evolving with scientific advances,” said Nicolas Rivron, a developmental biologist at the Institute of Molecular Biotechnology of the Austrian Academy of Sciences in Vienna. In a perspective published Thursday in Cell, he and an international group of leading luminaries in the fast-moving field of synthetic embryology — or “stembryology,” as it’s sometimes called — argue that these latest scientific advances justify a new definition for the human embryo that’s rooted not in how it was made, but in what it can become.

“Because of this new path, we think it becomes more and more important to think about the embryo not in terms of how it was formed but about the potential it has to generate something,” Rivron told STAT.

He and his co-authors proposed that embryos be defined as “a group of human cells supported by elements fulfilling extra-embryonic and uterine functions that, combined, have the potential to form a fetus.”

DALLAS – As the world continues to adapt to the growing trend of Artificial Intelligence (AI), South Korean scientists have unveiled a humanoid robot capable of piloting an aircraft.

Named Pibot, the life-sized robot, measuring 160 cm tall and weighing in at 65 kg, is capable of gripping the controls, memorizing aircraft manuals, and even responding to emergency situations. It is fitted with multiple cameras capable of monitoring the aircraft’s systems and operational conditions.

Currently under development by the Korea Advanced Institute of Science & Technology (KAIST), researchers utilized AI chatbots such as ChatGPT to create ways for PiBot to learn the pilot manuals for various aircraft. The robot can then be changed onto an alternative airframe by clicking the type. It can also memorize worldwide Jeppesen aeronautical navigation charts, an impossible task for its human equivalent.

Likewise, this dataset had 4,510 cases, 212,242 controls, with 16,380,464 SNPs for psoriasis, and 2,802 cases, 212,242 controls, with 16,380,459 SNPs for psoriasis vulgaris.

The team analyzed the aggregated statistical data using an MR approach to explore the potential causal relationship between the gut microbiome and psoriasis. SNPs with a threshold P-value of 1 × 10−5 worked as genetic instrumental variables in these MR analyses.

A new research paper was published by Aging (listed by MEDLINE/PubMed as “Aging (Albany NY)” and “Aging-US” by Web of Science) in Volume 15, Issue 15, entitled, “Associations between klotho and telomere biology in high stress caregivers.”

Aging biomarkers may be related to each other through direct co-regulation and/or through being regulated by common processes associated with chronological aging or stress. Klotho is an aging regulator that acts as a circulating hormone with critical involvement in regulating insulin signaling, phosphate homeostasis, oxidative stress, and age-related inflammatory functioning.

In this new study, researchers Ryan L. Brown, Elissa E. Epel, Jue Lin, Dena B. Dubal, and Aric A. Prather from the Department of Psychiatry and Behavioral Sciences, University of California, San Francisco, Department of Biochemistry and Biophysics, University of California, San Francisco, and the Department of Neurology and Weill Institute of Neurosciences, University of California, San Francisco discuss the association between klotho levels and telomere length of specific sorted immune cells among a healthy sample of mothers caregiving for a child with autism spectrum disorder (ASD) or a child without ASD — covarying age and body mass index — in order to understand if high stress associated with caregiving for a child with an ASD may be involved in any association between these aging biomarkers.

She uses Chat GPT to write computer code but says the applications are endless. “You need to cut what is not working in your company, go to the edges and start playing with this (AI) and see where it’s going to go. Because they’re predicting you either get on the AI train or you will be out of business in 10 years.”

CEO of the KR Digital Agency Kendra Ramirez says businesses can use AI to do work they don’t want to. “HR: who likes writing job descriptions? Anyone? No, no one. Performance reviews: One gentleman, his team, he had 50 people he had to do quarterly performance reviews.”

While optics and mechanics are two distinct branches of physics, they are connected. It is well known that the geometrical/ray treatment of light has direct analogies to mechanical descriptions of particle motion. However, connections between coherence wave optics and classical mechanics are rarely reported. Here we report links of the two through a systematic quantitative analysis of polarization and entanglement, two optical coherence properties under the wave description of light pioneered by Huygens and Fresnel. A generic complementary identity relation is obtained for arbitrary light fields. More surprisingly, through the barycentric coordinate system, optical polarization, entanglement, and their identity relation are shown to be quantitatively associated with the mechanical concepts of center of mass and moment of inertia via the Huygens-Steiner theorem for rigid body rotation.

A new study from the University of Minnesota is the first to demonstrate the ability for gene therapy to repair neural connections for those with the rare genetic brain disorder known as Hurler syndrome. The findings suggest the use of gene therapies—an entirely new standard for treatment—for those with brain disorders like Hurler syndrome, which have a devastating impact on those affected.
