The Indian Electric Vehicle market is set to reach a sales volume of 10.8 lakh units by 2025. However, these vehicles are currently at a high price and are not affordable to consumers in low-income categories.

To bridge this gap, a team of seven students at the KL University, Hyderabad have retrofitted an old and discarded bike into an EV.

“We also added futuristic features including wireless charging and cell balancing, which ensures equalised charging,” says Charan Sai (21), a fourth-year student of Electronics and Electrical Engineering, and the lead of the project.

The CRISPR system, which involves a Cas enzyme to cut DNA, is a powerful tool for gene editing. But the genetic scissors sometimes make changes at the wrong place, creating a major safety problem that could limit their therapeutic use.

Now, scientists at the University of Texas (UT) at Austin have refined the Cas9 protein used in the Nobel Prize-winning CRISPR-Cas9 tool. The new version, dubbed SuperFi-Cas9, was thousands of times less likely to perform off-target editing but just as efficient at on-target editing as the original version, the team said in a paper published in Nature.

“This really could be a game-changer in terms of a wider application of the CRISPR-Cas systems in gene editing,” Kenneth Johnson, Ph.D., the study’s co-senior author, said in a statement.

One day, we might be able to bring back to life every human ever lived, by the means of science and technology. And it will be a good day.

To the best of my knowledge, the idea was first described in detail by Fyodorov, a 19th century thinker.

Fyodorov argued that it is our moral duty to save our ancestors from the claws of death, to resurrect every human ever lived. And one day, we’ll have the technology.

Hydrogen gas could someday replace fossil fuels as a “clean” energy source, producing only water and energy. However, handling large quantities of gaseous hydrogen is cumbersome, and converting it to a liquid requires vessels that can withstand extremely high pressures. Now, researchers reporting in ACS Central Science have developed a method to store and release highly pure hydrogen with salts in the presence of amino acids.

The reversible storage of hydrogen in solid salts has emerged as one potential way to make the fuel easier to transport and handle, but the reactions to do this require precious metals as catalysts and may produce carbon dioxide as an unwanted byproduct. So, Henrik Junge, Matthias Beller and colleagues developed effective storage-release systems with both bicarbonate and carbonate salts, as well as manganese, which is a more widely available metal catalyst.

The researchers found that converting bicarbonate and hydrogen into formate, and vice versa, was most effective with potassium salts, a manganese-based catalyst and lysine—an amino acid that acted as an additional promoter and reacted with carbon dioxide to capture it—at reaction temperatures below 200 F. After five storage-release cycles, the reaction system produced hydrogen with a high yield (80%) and purity (99%).

Picture an entire city charged by batteries. This new battery design may unlock a new era of energy.

My name is Roman Stolyarov, and for my PhD work at the Media Lab I developed a terrain-adaptive control system for robotic leg prostheses. While modern prostheses allow people with leg amputations to get around, the way that they get around is often tiring, uncomfortable, and burdensome on their intact joints. In the worst case, irregular terrain geometries—from uneven sidewalks to rugged hiking trails—can be difficult or impossible to navigate with conventional prostheses, burdening the user’s mobility, independence, and sense of being able-bodied. My work was intended to help people with amputations feel as able-bodied and mobile as possible, by allowing them to walk seamlessly regardless of the ground terrain.
