In the quest for a greener future, the role of hydrogen in energy transition is undeniable. Amidst this shift, an innovative water engine has emerged, setting new power records and challenging the status quo. This breakthrough represents a significant leap in the decarbonization of the economy, where hydrogen (H) has become a crucial player.

The production of hydrogen for energy is a global focal point, with green hydrogen being a particularly strong contender. Investment in hydrogen production has surged worldwide. For instance, in Spain alone, 20% of the world’s new hydrogen projects were initiated in the first quarter of 2022. According to Wood Mackenzie, by the end of 2022, hydrogen-related projects had increased production to a total of 11.1 million tons per year.

In 2024, Gen Z workers are expected to outnumber baby boomers in the American labor force for the first time. Despite this shift, the youngest generation in the workforce, with the oldest members now 27, is often treated as a novelty. From email signatures to salary expectations, Gen Zers are scrutinized in every aspect of their professional lives. CNBC Make It delves into how Gen Z is truly making its mark on career advice, office culture, and more.

Gen Z, defined as individuals born between 1997 and 2012, is rethinking what it means to enter the workforce. According to a February 2024 Fiverr survey of 10,033 Gen Zers worldwide, 70% are currently freelancing or plan to do so in the future.

In a groundbreaking announcement, neuroscience and biomedical engineering startup BrainBridge has unveiled the world’s first head transplant system. This mind-bending concept proposes grafting a patient’s head onto a donor body, offering new hope to those suffering from untreatable conditions such as stage-4 cancer, paralysis, and neurodegenerative diseases like Alzheimer’s and Parkinson’s.

The ambitious procedure involves transplanting a patient’s head onto a healthy, brain-dead donor body, ensuring the preservation of consciousness, memories, and cognitive abilities. BrainBridge aims to make this futuristic system available within eight years, integrating advanced robotics and artificial intelligence to carry out the transplantation procedures.

PARIS, France — French automotive giant Peugeot has announced a partnership with Vay, a German mobility startup, to integrate “teledriving” technology into its vehicles. This innovative tech offers an alternative to autonomous cars, allowing vehicles to be remotely driven by human operators. The collaboration will focus on assessing the use of Vay’s teledriving technology in “last-mile delivery” vans and smaller logistics vehicles, targeting business-to-business (B2B) customers.

The concept aims to replicate the typical journey a delivery vehicle takes from an order fulfillment center to its final destination, whether it be households or businesses. Unlike self-driving cars, which operate without human intervention, teledriven cars are controlled remotely by human drivers who navigate using a live feed of the vehicle’s surroundings. These teledrivers undergo several weeks of rigorous training and must receive certification before operating one of Vay’s teledrive stations.

In the absence of electronic computational tasks, our daily lives would be drastically different. Everyday devices like elevators, vending machines, turnstiles, washing machines, and traffic lights rely on simple electronic computing to switch states. But what if these devices could operate without a power supply? A research team led by Martin van Hecke from Leiden University and AMOLF has demonstrated how smart rubber structures can carry out these computational tasks. “We now know how to design simple materials so they can process information,” van Hecke stated.

Their study, published on May 20 in the Proceedings of the National Academy of Sciences, showcases a groundbreaking approach to computation using mechanical systems. Traditionally, electronic devices perform calculations with digital bits and complex circuits. However, the researchers have found an innovative way to compute using slender rubber elements as mechanical bits, assembling them into a “metamaterial.” The key to making these materials function as machines lies in controlling the interactions between the individual bits.

Though the automotive industry has long utilized 3D printing technology, its potential in end-part production and maintenance, repair, and overhaul (MRO) operations has been underutilized. While companies like BMW are developing automated additive manufacturing (AM) lines for car components, MRO applications lag behind. Harold Sears, a Ford veteran and 3D printing expert, emphasized the importance of standards and quality control for applying AM in auto repair. This need prompted Sears and others to launch the 3D Printing in Auto Repair Task Force with the International Bodyshop Industry Symposium (IBIS).

Following the Task Force’s report on the state of AM in auto repair published in October 2023, progress has been anticipated in this crucial segment. At the IBIS Worldwide event in Greece, a new business named Auto Additive emerged, leveraging the Task Force’s expertise and technology to address AM for auto repair.

Concrete and steel production are major contributors to CO2 emissions, but researchers from Cambridge University have developed a revolutionary solution that could recycle both materials simultaneously. By introducing old concrete into steel-processing furnaces, the process not only purifies iron but also produces “reactivated cement” as a byproduct. When powered by renewable energy, this method could potentially yield carbon-zero cement.

Scientists have long sought to make concrete more environmentally friendly. Efforts include altering the concrete mix to replace the most polluting ingredients, such as limestone, or designing concrete to absorb more CO2 from the atmosphere after being laid. In their new study, Cambridge researchers explored how waste concrete could be transformed back into clinker—the dry component of cement—ready for reuse.

Scientists have developed a groundbreaking technique to synthesize diamonds at normal atmospheric pressure without the need for a starter gem, potentially simplifying the production of these precious gemstones in the lab.

Traditionally, natural diamonds form in Earth’s mantle, the molten zone buried hundreds of miles beneath the planet’s surface. This natural process occurs under immense pressures of several gigapascals and scorching temperatures exceeding 2,700 degrees Fahrenheit (1,500 degrees Celsius).
