The new design came with three fundamental improvements.
Researchers have finally managed to reduce the two-photon fluorescence microscope into a thumb size device that allows them to see inside the brain of live and active animals. The device called Mini2P weighs just 2.4 grams and can be attached to a mouse’s head without compromising its natural movements.
The microscope can record live images of neural landscapes, the likes of which have never been seen before. The innovation “opens the door to lines of scientific inquiry that were difficult, if not impossible, to initiate,” says Denise Cai, a neuroscientist at the Icahn School of Medicine at Mount Sinai in New York City. feat was achieved by Edvard Moser, professor of Psychology and Neuroscience at the Kavli Institute for Systems Neuroscience, together with Weijing Zong, a biological engineer and neuroscientist at the Moser Group.
Dr. Peter Fedichev, Ph.D. is the CEO of Gero (https://gero.ai/), a biotech company focused on hacking complex diseases, including aging, with AI for novel drug discovery, as well as digital biomarkers.
Gero’s models originate from the physics of complex dynamic systems, combining the potential of deep neural networks with the physical models to study dynamical processes and understand what drives diseases.
Dr. Fedichev has a background in biophysics, bioinformatics and condensed matter physics, earning his Ph.D. from the University of Amsterdam, and he conducted research at FOM Institute AMOLF (part of the institutes organization of the Dutch Research Council of Netherlands) and the University of Innsbruck.
To date, Dr Fedichev has published over 70 papers covering his research on physics, biophysics and aging biology.
Oocytes prevent the production of reactive oxygen species by remodelling the mitochondrial electron transport chain through elimination of complex I, a strategy that enables their long-term viability.
Turtles, unlike humans, do not continue to age once their bodies reach adulthood because they are “negligibly senescent.” It is theoretically possible for them to live indefinitely, although it is unlikely to happen in actuality. They will eventually die of injury, predation, or sickness. It has been documented that tortoises and their cousins, turtles, can live for up to two hundred years without showing any signs of aging. A turtle that is a hundred years old can experience the same feelings of youth as a tortoise that is thirty years old. This enviable trait may be found in both fish and amphibians. The idea of aging terrifies humans, and it is understandable why. Nobody wants to age slowly and painfully into a state of ill health and old age where death appears preferable to life. However, not everyone thinks this way. There are others who desire to live longer, perhaps even indefinitely. And while a life without aging might sound like something that could only be found in the pages of a fantasy story, research in the field of science suggests that this possibility is very much within our reach.

Scientists have shown that they can detect SARS-CoV-2, the virus that causes COVID-19, in the air by using a nanotechnology-packed bubble that spills its chemical contents like a broken piñata when encountering the virus.
Such a detector could be positioned on a wall or ceiling, or in an air duct, where there’s constant air movement, to alert occupants immediately when even a trace level of the virus is present.
The heart of the nanotechnology is a micelle, a molecular structure composed of oils, fats and sometimes water with inner space that can be filled with air or another substance. Micelles are often used to deliver anticancer drugs in the body and are a staple in soaps and detergents. Almost everyone has encountered a micelle in the form of soap bubbles.
The ability to analyze the properties of individual cells is vital to broad areas of life science applications, from diagnosing diseases and developing better therapeutics to characterizing pathogenic bacteria and developing cells for bioproduction applications. However, the accurate analysis of individual cells is a challenge, especially when it comes to a cell’s biophysical properties, due to large property variations among cells even in the same cell population as well as the presence of rare cell types within a larger population.
Addressing this need, Dr. Arum Han, Texas Instruments Professor II in the Department of Electrical and Computer Engineering at Texas A&M University, together with his graduate students and postdoctoral researchers, have developed a new technology that can accurately analyze cell properties through the use of a single-cell electrorotation microfluidic device, which utilizes an electric field to probe the cell’s properties.
The technology works by using an electric field to first capture a single cell in a microfluidic device, followed by applying a rotating electric field to rotate the trapped single cell and then measuring the speed of rotation. By knowing the input electric field parameters and analyzing the rotation speed, accurately analyzing the dielectric properties of a single cell becomes possible.
Extending the limit of the human lifespan. The first immortal human has already been born. “The first human to live to 1,000 has already been born” – Dr. Aubrey de Grey. How far are we in understanding aging and death? Do we have to age or is it a matter of a choice? What is the future of immortality? Is it possible to be immortal and if yes — how far are we in implementing medical treatment and technology that can forestall this natural process we have always thought “is just how life is”. In this video I am reviewing the cutting-edge technologies and the pioneers in the field of extending life expectancy and reaching immortality eventually. Hint: is it closer than you might imagine!

Reporting in Research Ideas and Outcomes, a Kyushu University researcher has developed a new technique for scanning various plants and animals and reconstructing them into highly detailed 3D models. To date, over 1,400 models have been made available online for public use.
Open any textbook or nature magazine and you will find stunning high-resolution pictures of the diverse flora and fauna that encompass our world. From the botanical illustrations in Dioscorides’ De materia medica (50−70 CE) to Robert Hooke’s sketches of the microscopic world in Micrographia (1665), scientists and artists alike have worked meticulously to draw the true majesty of nature.
The advent of photography has given us even more detailed images of animals and plants both big and small, in some cases providing new information on an organism’s morphology. As technology developed, digital libraries began to grow, giving us near unfettered access to valuable data, with methods like computer tomography, or CT, and MRI scanning becoming powerful tools for studying the internal structure of such creatures.
Research in the field of machine learning and AI, now a key technology in practically every industry and company, is far too voluminous for anyone to read it all. This column, Perceptron, aims to collect some of the most relevant recent discoveries and papers — particularly in, but not limited to, artificial intelligence — and explain why they matter.
Over the past few weeks, researchers at MIT have detailed their work on a system to track the progression of Parkinson’s patients by continuously monitoring their gait speed. Elsewhere, Whale Safe, a project spearheaded by the Benioff Ocean Science Laboratory and partners, launched buoys equipped with AI-powered sensors in an experiment to prevent ships from striking whales. Other aspects of ecology and academics also saw advances powered by machine learning.
The MIT Parkinson’s-tracking effort aims to help clinicians overcome challenges in treating the estimated 10 million people afflicted by the disease globally. Typically, Parkinson’s patients’ motor skills and cognitive functions are evaluated during clinical visits, but these can be skewed by outside factors like tiredness. Add to that fact that commuting to an office is too overwhelming a prospect for many patients, and their situation grows starker.
