A nuclear battery powered by radioactive decay rather than chemical reactions could last for decades. The most efficient design yet may bring this concept closer to reality.

Researchers have wanted to use radioactive atoms to build exceptionally long-lasting and damage-resistant batteries since the 1900s. While some prototypes have been assembled and even used in space missions, they were not very efficient. Now Shuao Wang at Soochow University in China and his colleagues have improved the efficiency of a nuclear battery design by a factor of 8000.

They started with a small sample of the element americium, which is usually considered to be nuclear waste. It radiates energy in the form of alpha particles, which carry lots of energy but quickly lose it to their surroundings. So the researchers embedded americium into a polymer crystal that converted this energy into a sustained and stable green glow.

Then they combined the glowing americium-doped crystal with a thin photovoltaic cell, a device that converts light to electricity. Finally, they packaged the tiny nuclear battery into a millimetre-sized quartz cell.

Over 200 hours of testing, Wang says, the device produced a stable supply of electricity at a relatively high energy with unprecedented efficiency – and it only needed minimal amounts of radioactive material to function. Although americium has a half-life of 7380 years, the nuclear battery should run for several decades, because the components surrounding the sample will eventually be destroyed by the radiation.

Michael Spencer at Morgan State University in Maryland says the new battery has “much improved overall conversion efficiencies and output power” compared to past designs. However, it still produces much less power than conventional devices. It would take 40 billion of them to power a 60-watt light bulb, for instance.

The researchers are already working on improving their design’s efficiency and power output. They also want to make it easier and safer to use, since it contains possibly dangerous radioactive materials.

“Ideally, we envision our micronuclear battery being used to power miniature sensors in remote or challenging environments where traditional power sources are impractical, like deep-sea exploration, space missions or remote monitoring stations,” says Wang.

SpaceX launches 21 Starlink satellites, but rocket's first stage crashes on landing barge


After standing down from the piloted Polaris Dawn launch late Tuesday, SpaceX shifted gears and pressed ahead with plans for back-to-back launches of Starlink internet satellites early Wednesday, one from Florida and the other from California.

But the second flight was called off after the first stage used in the Florida launch toppled into the Atlantic Ocean and broke apart while attempting to land on a SpaceX droneship stationed several hundred miles northeast of Cape Canaveral. The landing mishap ended a string of 267 successful booster recoveries dating back to February 2021.

The Falcon 9’s second stage, meanwhile, successfully carried 21 Starlink satellites to their planned orbit.

The first stage landing appeared normal until the moment of touchdown when more flames than usual were visible around the base of the rocket as it neared the deck. A landing leg immediately collapsed on touchdown and the booster, obscured by fire and smoke, tipped over the side of the landing barge into the Atlantic.

“After a successful ascent, Falcon 9’s first stage booster tipped over following touchdown on the A Shortfall of Gravitas droneship,” SpaceX said on the social media site X. “Teams are assessing the booster’s flight data and status.”

4 Pillars to Creating Effective AI Prompts

4 Pillars to Creating Effective AI Prompts

In the exciting world of Artificial Intelligence (AI), prompts are instructions or queries you enter into the AI interface to get responses. If you want helpful responses, you need to know how to input useful information and instructions. Known as AI prompt engineering, it’s a strategy that focuses on designing strategic prompts to guide machine learning models (MLMs) and large language models (LLMs) toward the desired output. Instead of just a question, well-thought-out prompts act like soft programming, resulting in specific responses with enhanced accuracy and value.

This is a good time to clarify something. A prompt is not the same as a ‘search.’ Search is when you look for information on a particular topic using keywords and get a list of results that more or less match the query. As noted above, AI prompt engineering is direct and leads to a specific response.

Whether you’re new to prompt writing or looking for quick tips on how to write effective AI prompts, we’re sharing our four tried-and-tested pillars to creating AI prompts (*pro tip: bookmark this article or print this simplified version to keep on your desk!). While these pillars are specifically designed to improve the quality of response when using Mintel Leap—our new, closed-loop generative AI tool—they absolutely apply no matter what gen AI tool you happen to be using.

Four pillars to creating AI prompts

The best AI prompts start with a good question, but it’s so much more than that.

  1. Category: What category/industry are you searching? CPG? Beauty? Financial Services?
  2. Market: Are you looking into a specific country or region?
  3. Audience: Who are you targeting? Gen Z? Families? Over 65?
  4. Time Frame: Are you looking at the last 5 years? Next 3 years?

Using the direction of the four pillars above, let’s explore an example of creating effective AI prompts:

“What are the key trends driving younger consumer preference in the housecleaning category in the US market over the next five years?”

Polishing your prompt writing skills

Let’s explore how the four pillars provide direction across a handful of sectors and teams, including an insights team at an advertising agency, a marketing team in the financial services sector, and an innovation team in the food and drink industry.

Prompt building for an Agency Insights team

A strategist at an agency wants to market a new RTD coffee to Gen Z in the US:

  • Initial question: What are current and future RTD coffee trends in the US?
  • In the form of a prompt: Tell me the current and future RTD coffee trends aimed at Gen Z in the US.
  • Applying the four pillars: What are the current and future RTD coffee trends aimed at Gen Z in the US? Based on this information, build me a step-by-step strategy to market our new RTD coffee to Gen Z.

Prompt building for a Financial Services Marketing team

A major bank in the UK wants to grow its customer count, focusing especially on higher-income Millennials:

  • Initial question: How can brands resonate with Millennials?
  • In the form of a prompt: I want to grow my banking customer count by focusing on higher-income Millennials in the UK. How can I resonate with Millennials’ financial ambitions and position the brand as a tool for financial growth or wealth building?
  • Applying the four pillars: I want to grow my banking customer count by focusing on higher-income Millennials in the UK. How can brand messaging resonate with their financial ambitions and position the brand as a tool for financial growth or wealth building? Based on this, create a list of actions to take from most important to least important.

Prompt building for a Food and Drink Innovation team

A yogurt innovation team is in charge of developing a new product targeted at seniors in Japan. They want to gather as much information as possible to create the most appealing product.

  • Initial question: What yogurts appeal to seniors?
  • In the form of a prompt: I want to create a yogurt targeted at seniors. What should I do?
  • Applying the four pillars: I want to create a yogurt targeted at seniors in Japan. First, tell me what I should focus on. Then, based on this, come up with the three best yogurt concepts.

How to handle AI prompt issues

The biggest issue most of us face with generative AI is providing clear instructions. While it is important to provide context, conciseness is equally crucial. Verbose prompts can confuse the AI or lead it to focus on less relevant aspects of your prompt. You may need to refine your prompt and build on the analysis with additional prompts as you go along. From the start, aim for a balance by providing enough detail for clarity and context, but be as concise as possible.

Marketing, Research, and Innovation prompts from Mintel Leap users

Mintel Leap is designed to transform hours of research into answers in seconds. It’s a tool you can trust, as it only analyzes Mintel’s proprietary research and human analysis (based on the client’s subscription).

For a better understanding, check out this on-demand demo.

FAA grounds SpaceX Falcon 9 rockets pending investigation of rare offshore crash-landing


The Federal Aviation Administration has grounded SpaceX’s Falcon 9 rockets pending an investigation to determine what caused a first-stage booster to crash onto a landing barge early Wednesday after helping launch another batch of Starlink internet satellites.

After standing down from the piloted Polaris Dawn launch late Tuesday because of an unfavorable long-range forecast, SpaceX pressed ahead with the first of two planned back-to-back launches of Starlinks, one from Florida and the other from California.

But the second flight was called off after the first stage used in the Florida launch crash-landed and toppled into the Atlantic Ocean while attempting to touch down on a SpaceX droneship stationed several hundred miles northeast of Cape Canaveral.

This photo was taken from pad 39A at the nearby Kennedy Space Center, where the Polaris Dawn mission awaits liftoff on a commercial flight featuring the first non-government spacewalk. That flight now is on hold pending an investigation into what caused the first stage of the Starlink rocket to crash-land during touchdown on an offshore SpaceX droneship.

The FAA said it would require an investigation, effectively grounding SpaceX’s Falcon 9 rockets — including the Polaris Dawn booster — until the probe is complete and corrective actions are approved.

“A return to flight of the Falcon 9 booster rocket is based on the FAA determining that any system, process or procedure related to the anomaly does not affect public safety,” the FAA said in a statement.

“In addition, SpaceX may need to request and receive approval from the FAA to modify its license that incorporates any corrective actions and meet all other licensing requirements,” the agency said.

Late Tuesday, SpaceX delayed Wednesday’s planned launch of the Polaris Dawn mission, a commercial flight featuring what will be the first non-government spacewalk, to Friday at the earliest because of predicted end-of-mission splashdown weather. The launching now is on indefinite hold pending the landing mishap investigation.

The landing failure ended a string of 267 successful booster recoveries in a row dating back to February 2021. The Falcon 9’s second stage, however, successfully carried 21 Starlink internet satellites to their planned orbit.

The first stage landing appeared normal until the moment of touchdown when more flames than usual were visible around the base of the rocket as it neared the deck. A landing leg immediately collapsed on touchdown and the booster, obscured by fire and smoke, tipped over the side of the landing barge into the Atlantic Ocean.

It’s a shark eat shark world. Researchers find evidence that large sharks may be hunting each other.

It's a shark eat shark world. Researchers find evidence that large sharks may be hunting each other.


In the ocean food chain, large sharks generally only have to worry about keeping orcas at bay — but a new study suggests the apex predators may have to watch out for their own.

Researchers have discovered evidence pointing to the first known case of a porbeagle shark — which can grow up to 12 feet long and 500 pounds — being killed by a large shark predator. The findings were published Tuesday in the biology journal Frontiers in Marine Science.

This isn’t the first case of “shark cannibalism,”  said Jon Dodd, executive director of the Atlantic Shark Institute, which helped lead the study. Larger sharks eating smaller sharks is a common occurrence, “in the open ocean, size matters, but there is always something bigger,” he said.

In some cases — bull sharks, mako sharks and baby sand tiger sharks, for example — sharks will even eat their own species.

But cases of large sharks eating other large sharks, the subject of this study, are few and far between, said lead author Dr. Brooke Anderson, a marine biologist for the North Carolina Department of Environmental Quality. 

The fatality of the female porbeagle raises questions about whether this incident represents a wider trend among large predators, said Anderson. “With the advancements in technology, it’s possible that this happens more frequently than we’ve just really been able to discover,” said Anderson.  

The number of sharks eaten by other sharks is impossible to know, said Dodd adding, “but if our experiences at the Atlantic Shark Institute are an indicator, it might be more than we think.”

A group of scientific researchers from across the U.S. discovered the porbeagle death while conducting a satellite tracking project in the Northwestern Atlantic to better understand the shark species’ whereabouts, behaviors and environmental preferences. They were particularly curious about female porbeagles, which are known to traverse long swaths of the ocean to deliver their pups. 

“We were really seeking to understand the habitats used by the pregnant females and try to figure out where they might be going to give birth,” said Anderson.

The victim of the attack, nicknamed Penelope by researchers, was one of the 11 sharks scientists tagged off the coast of Cape Cod in 2020 and 2022. Tracking tags were placed on the dorsal fins of the sharks and used to collect information on water depth and temperature. The tags stored the data until they eventually fell off the sharks, at which point the data was transmitted back to the researchers via satellite.

The tracking devices were designed to stay on for a year, but five months into the experiment, Penelope’s data had already come in. “As soon as I got the data from that tag, I immediately knew something weird had happened,” Anderson said. 

A few days before Penelope’s tag popped off along the coast of Bermuda, the temperature of the water suddenly spiked. It remained relatively high, even when it reached 600 meters below sea level, which is “very unusual,” Anderson explained.

Anderson and her colleagues came to a harrowing conclusion: the porbeagle had been hunted and eaten by another behemoth of the sea. “The only explanation for that data is that this tab is now in the stomach of a predator,” Anderson told CBS News.

Researchers don’t know with 100% certainty what the culprit was, but the diving pattern of the predator, which researchers tracked by looking at the depth data collected by the tag, was similar to that of white sharks they’ve monitored in the past. “Based on that, it was likely, I’d guess, a mature female white shark,” said Anderson.

Porbeagles, which have historically been overfished, are considered endangered in certain parts of the world. Given they are already at risk, Anderson said the loss of pregnant females and their babies could prove devastating to the population.

And sharks aren’t the only ones that could feel the ripple effects of this change. The rulers of the deep maintain the balance of the underwater ecosystem by keeping smaller predator populations in check and adding vital nutrients to shallow waters

“Humans heavily rely on oceans for food and many other things and the oceans need healthy shark populations,” Anderson said.

The Star Wars Jedi series will end with the third and final game

The Star Wars Jedi series will end with the third and final game

The Star Wars Jedi series has been pretty popular since it debuted back in 2019, and the coming installment of the third game is likely to show just as much promise as the first two games in the series. It’s also reportedly going to be the last game in the series, according to EA. The publishing company has confirmed that a third installment of Star Wars Jedi, said to be a sequel to Star Wars Jedi: Survivor is in the works.

EA has also confirmed that this third game will be the “final chapter” making this a trilogy. The first two games and the third installment in the series are all developed by Respawn Entertainment. The same development studio behind Titan Fall and Apex Legends.

While we don’t know how far along in development the game is, EA says that Respawn is already working on the game. The publishing company mentioned these details at its recent EA Investor Days conference. This took place on September 17 (via Insider Gaming and GameRant). Interestingly, EA’s conference was held on the same day Star Wars Jedi: Survivor was released for the PS4 and Xbox One. It was originally released for PC, PS5, and Xbox Series X|S back on April 28, 2023.

EA doesn’t mention any specifics about the third Star Wars Jedi game

With EA confirming a third game is in development, fans no doubt want to know everything they can about the game. When it’s coming, what the story will be, what new features will be included. All of that will no doubt come in time, but EA hasn’t shared any of those details as of yet. Nothing other than the fact that the game is in development was mentioned during the investor conference. The only thing that is probably safe to assume is that the series’ main character, Cal Kestis, will return to be the main playable character in the final game.

Will this new game come to PS4 and Xbox One as well?

It’s tough to say. It can’t be confirmed what platforms the game will be released on. Especially with EA sharing absolutely nothing about the game at this time. Since Jedi Survivor was released on PS4 and Xbox One, it’s certainly possible.

How likely it is will be another story. Even if it is released on PS4 and Xbox One, that may not happen right away. It could end up being more than a year after PC and current-gen consoles just like with Jedi Survivor. That’s even if the game releases this gen in the first place.
