Is this the beginning of the age of bionic humans?

But while medical research facilities are subject to privacy laws, private companies — that are amassing large caches of brain data — are not. Based on a study by The Neurorights Foundation, two-thirds of them are already sharing or selling the data with third parties. The vast majority of them also don’t disclose where the data is stored, how long they keep it, who has access to it, and what happens if there’s a security breach…
This is why Pauzauskie, Medical Director of The Neurorights Foundation, led the passage of a first-in-the-nation law in Colorado. It includes biological or brain data in the State Privacy Act, similar to fingerprints if the data is being used to identify people.
“This is a first step, but we still have a long way to go,” he says.

– A glimmer of hope emerged today for rectal cancer patients as a collaborative effort between Case Western Reserve University (CWRU), Cleveland Clinic, and University Hospitals (UH) received a $2.78 million grant over five years from the National Institutes of Health and National Cancer Institute. This grant will fuel research leveraging artificial intelligence (AI) to personalize treatment for rectal cancer patients.
– The new research effort signifies a significant step forward in the fight against rectal cancer. By harnessing the power of AI, researchers are on the path to developing more precise treatment strategies, ultimately improving patient outcomes and quality of life.
Researchers from MIT and the University of Texas have developed a prototype for a handheld, chip-based 3D printer using a photonic chip that emits beams of light to cure resin into solid objects. This innovative technology could revolutionize the production of customized, low-cost objects on-the-go and has potential applications in medical and engineering fields.
Portable 3D Printing Technology
Imagine a portable 3D printer you could hold in the palm of your hand. The tiny device could enable a user to rapidly create customized, low-cost objects on the go, like a fastener to repair a wobbly bicycle wheel or a component for a critical medical operation.
Summary: Researchers made a significant discovery in the study of human brain evolution, identifying epiregulin as a key factor in the expansion of the human neocortex. By comparing brain development between mice and humans and utilizing 3D brain organoids, the team found that epiregulin promotes the division and expansion of stem cells, crucial for neocortex development.
This study, which utilized cutting-edge 3D culture technology, suggests that the quantity of epiregulin, rather than its presence or absence, distinguishes human brain development from that of other species, including primates like gorillas. The research offers new insights into what makes the human brain unique and underscores the value of innovative methodologies in understanding complex evolutionary processes.
Gold nanoparticles have been the subject of intense research for several decades due to their interesting applications in fields such as catalysis and medicine. “Surface ligands” are organic molecules typically present on the surface of gold nanoparticles. During synthesis, these surface ligands play an important role in controlling the size and shape of the nanoparticles.
For several decades, the CIC biomaGUNE team led by Ikerbasque Research Professor Luis Liz-Marzán has studied in detail the growth mechanisms and properties of these nanoparticles. Despite numerous advances that have recognized the importance of surface ligands, many questions remain about their exact behavior during and after growth. Direct observation of surface ligands and their interface with gold nanoparticles has therefore been a long-standing goal for many scientists in this field.
Transmission Electron Microscopy (TEM) is the technique most widely used to investigate nanoparticles. However, the study of surface ligands by means of TEM presents significant challenges; the reason is that the ligands are sensitive to the electron beam, their contrast is limited and their structure in vacuum differs from their native state in solution.
In pre-clinical trials, a small molecule effectively regrew neurons, reduced inflammation, and improved memory, speed, coordination, grip strength, and more. The finding could have a profound impact on aging and the diseases that accompany it.
In conducting the research, scientists at the University of Texas MD Anderson Cancer Center, turned their focus to telomerase reverse transcriptase (TERT), an enzyme that is known to help synthesize and extend telomeres, the protective caps at the ends of chromosomes that help cells divide. TERT levels are reduced as we age.
Without sufficient levels of TERT, when our telomeres shrink or get seriously modified, they can lead to a process that continually damages our DNA, which causes cells to release inflammatory compounds that can in turn lead to aging, tissue damage, and cancer.
A new technique combining magnetic resonance imaging and x-ray fluorescence can characterize, with single-neuron resolution, the presence of toxic forms of iron that might be associated with neurodegenerative diseases.
Iron plays a major role in life. Most obviously, it keeps us alive, helping to ferry oxygen around our bloodstreams. It is also essential in cellular energy production, in the immune-system response, and in brain function—where it helps catalyze the synthesis of dopamine and other neurotransmitters. Iron can, however, be a double-edged sword. An iron excess has been implicated in many ailments, including neurodegenerative conditions such as Alzheimer’s, multiple sclerosis, and Parkinson’s disease—where dopaminergic neurons (neurons that use iron to synthesize dopamine) degenerate. It is thought that the toxicity of iron depends on how it is stored: iron firmly bound within proteins such as ferritin may be less toxic than iron more loosely bound to low-affinity sites, where it is more able to participate in reactions that generate cell-damaging hydroxyl radicals [1].
Adjusting experimental methods achieved the first “single-shot” diagnosis of electron acceleration through a laser wakefield accelerator along a curved trajectory, according to a recent study led by University of Michigan researchers. The findings are published in the journal Physical Review Letters.
This optical-based technique could help engineers develop more powerful electron accelerators for fundamental studies of quantum and particle physics —or more compact accelerators for use in medicine and industry.
Compared to traditional accelerators which can be kilometers long, laser wakefield accelerators can apply 1,000 times more energy per meter, allowing a vastly more compact design able to fit into a large room.
