Scientists from the Micro, Nano and Molecular Systems Lab at the Max Planck Institute for Medical Research and the Institute for Molecular Systems Engineering and Advanced Materials at Heidelberg University have created a new technology to assemble matter in 3D. Their concept uses multiple acoustic holograms to generate pressure fields with which solid particles, gel beads and even biological cells can be printed.

These results pave the way for novel 3D cell culture techniques with applications in biomedical engineering. The results of the study were published in the journal Science Advances.

Additive manufacturing or 3D printing enables the fabrication of complex parts from functional or biological materials. Conventional 3D printing can be a slow process, where objects are constructed one line or one layer at a time. Researchers in Heidelberg and Tübingen now demonstrate how to form a 3D object from smaller building blocks in just a single step.

When it comes to DNA, one pesky mosquito turns out to be a rebel among species.

Researchers at Rice University’s Center for Theoretical Biological Physics (CTBP) are among the pioneers of a new approach to studying DNA. Instead of focusing on chromosomes as linear sequences of genetic code, they’re looking for clues on how their folded 3D shapes might determine gene expression and regulation.

For most living things, their threadlike chromosomes fold to fit inside the nuclei of cells in one of two ways. But the chromosomes of the Aedes aegypti mosquito—which is responsible for the transmission of tropical diseases such as dengue, chikungunya, Zika, mayaro and yellow fever—defy this dichotomy, taking researchers at the CTBP by surprise.

The first time a language model was used to synthesize human proteins.

Of late, AI models are really flexing their muscles. We have recently seen how ChatGPT has become a poster child for platforms that comprehend human languages. Now a team of researchers has tested a language model to create amino acid sequences, showcasing abilities to replicate human biology and evolution.

The language model, which is named ProGen, is capable of generating protein sequences with a certain degree of control. The result was achieved by training the model to learn the composition of proteins. The experiment marks the first time a language model was used to synthesize human proteins.

The rise of social media has changed our day to day lives. But more and more reports show that social media and especially social media can impact our brain. Social media addiction might also to a decline in mental health. How does social media changes us? And are the effects by social media addiction reversal?

Savant syndrome is a strange condition that gives people unique abilities. Although savant syndrome is very rare reported cases gain genius-like abilities in narrow domains. But how can we explain savant syndrome? And could we induce savant syndrome in normal people?

We all know that exercise is good for our health. But besides lowering the risk of obesity or type II diabetes, exercise has also been shown to benefit our brain. More precisely, exercise modifies parts of the brain and improves memory, attention and improves mood. Regular exercise further lowers the risk to suffer from dementia or depression. But how does exercise benefit our brains?

The new disease could provide insights into how the cell’s recycling system contributes to a healthy brain. Researchers at the National Institutes of Health have discovered a new neurological condition characterized by issues with motor coordination and speech. They identified three children with the condition, two siblings and an unrelated child.

These molecules, which could be up to 170,000 years old, could one day help yield the most complete picture yet of Neanderthal life.

The calcite-encrusted skeleton of an ancient human, still embedded in rock deep inside a cave in Italy, has yielded the oldest Neanderthal DNA ever found.

Of the respondents, 28 percent said they were more likely than not to use gene editing to make their babies smarter, and 38 percent said they’d use polygenic screening. The researchers also noted what they called a bandwagon effect, where people who were told something along the lines of “everyone else is doing it” were more likely to say they’d do it too. This is logical; our comfort with decisions is buoyed by a sense that others in our shoes would choose similarly.

It’s important to note, though, that the survey made it clear that genetically enhancing embryos didn’t come with a guaranteed result of a smarter kid. “In this study, we stipulated a realistic effect—that each service would increase the odds of having a child who attends a top-100 college by 2 percentage points, from 3 percent to 5 percent odds—and lots of people are still interested,” said Michelle N. Meyer, chair of the Department of Bioethics and Decision Sciences at Geisinger and first author of the article.

The numbers—28 and 38 percent—don’t seem high. That’s a little below and a little above one-third of total respondents who would use the technologies. But imagine walking around in a world where one out of every three people had had their genes tweaked before birth. Unsettling, no? The researchers said their results point to substantial and growing interest in genetic technologies for offspring enhancement, and that now is the time to get a national conversation going around regulations.
