Adult cells in our body can only give rise to the same cell type. For example, a skin cell cannot give rise to a muscle cell but to skin cells only. This limits the potential use of adult cells for therapy. During early development, however, the cells in the embryo have the capacity to generate all cell types of our body, including stem cells. This capacity, which is called totipotency, has served as an inspiration for researchers to find new ways to recapitulate totipotency through cellular reprogramming in the lab.
Totipotent cells have their own speed
Totipotent cells have many properties, but we do not know all of them yet. Researchers at Helmholtz Munich have now made a new discovery: “We found out that in totipotent cells, the mother cells of stem cells, DNA replication occurs at a different pace compared to other more differentiated cells. It is much slower than in any other cell type we studied,” says Tsunetoshi Nakatani, first-author of the new study.
Researchers have restored muscle function in research animals with gene therapy. The approach could someday lead to new treatment methods in the elderly.
A team of researchers from Monash University’s Faculty of Engineering have redesigned the heart of a lithium-sulfur battery, creating a new interlayer that allows for exceptionally fast lithium transfer, as well as an improvement in the performance and lifetime of the batteries.

Earlier this year, a space rock was estimated to hit the planet in 2023. Read on to know how this prediction changed, and how astronomers carry out studies for this type of event.
There is an exciting branch of battery research that involves combining the strength and durability of next-generation materials with their energy storage potential. This could see car panels double as their batteries, for example, and in a new example of what this could look like scientists have developed a “power suit” for electric vehicles that could not only extend their range, but give them a handy boost in acceleration at the same time.
Sometimes known as structural batteries, we’ve seen some interesting recent advances in this space from research groups and even big-name automakers. Back in 2013, Volvo demonstrated carbon fiber body panels with energy storage potential, and we’ve seen other teams show off similar concepts since. These projects sought to combine the high energy density of batteries with the ultra-fast discharge rates of supercapacitors, in materials strong enough to serve as a car’s exterior.
This new breakthrough continues this line of thinking, with scientists at University of Central Florida and NASA designing a new material featuring unique properties that allow for not just impressive energy storage potential, but also the strength needed to endure a car crash.
The world’s first demonstration device to produce 1,000 tons of gasoline per year from carbon dioxide (CO2) hydrogenation has completed its technology evaluation and trial operation.
Located in the Zoucheng Industrial Park, Shandong province, China, the project has been jointly developed by the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) and the Zhuhai Futian Energy Technology company. The hydrogenation of CO2 into liquid fuels and chemicals can not only realize the resource utilization of CO2 but also facilitate the storage and transportation of renewable energy.
However, activation and selective conversion of CO2 are challenging. A technology that can selectively produce energy-dense, value-added hydrocarbon fuels will provide a new route to promote the clean, low-carbon energy revolution.

This could lead to the emergence of life.
Astronomers detected the largest molecule ever found in a planet forming disc, which could lead to organic molecules.
Statement from members of the earth and space science international community.
We are Earth and space scientists, science communicators, and educators dedicated to the discovery of and solutions to societal challenges. We issue this joint statement to call on world governments and global leaders to do everything possible to expedite the end to the brutal Russian assault on Ukraine. We welcome other professional scientific communities to join our appeal.
1. The Earth and Space Community is an ecosystem of researchers working together and supporting each other. At this moment, our colleagues in Ukraine are being shelled with missiles and many have been forced to escape with their families from the war zone. We salute “Science for Ukraine” grassroots efforts and urge world governments to support Ukrainian students and science professionals.
