Technosignature research is heating up, with plenty of papers speculating on the nature, and sometimes the longevity, of signals created by technically advanced extraterrestrial civilizations. While we haven't found any so far, that isn't to say that we won't, and a better understanding of what to look for would undoubtedly help.

"Missing Girls in Historical Europe" is a major research project at NTNU in which researchers have looked into numbers of girls and boys in European countries over a 250-year period. They found that the number of male children was higher in several countries during periods of poverty and poor living conditions.

Months of record breaking temperatures and the El Niño weather phenomenon pushed the heating up of the world's oceans to a new peak in February, scientists said.

A paper published in International Journal of Innovation and Technology Management aims to show that the network of frequent relationships established between agents in coworking environments, through weak ties, increases the generation of ideas. The paper is titled "Open Creativity: Increased Creativity Due to Network Relationships in Coworking Environments."

Parents considering posting pictures and information of their children online should re-think how they go about it, in a new warning from Edith Cowan University (ECU) data experts.

Transition metal selenides have been considered to be a good choice for electrocatalytic water splitting. In addition, Metal-organic frameworks (MOFs) have been used to make catalysts with good electrocatalytic capabilities. Traditionally, the MOF-derived selenides are produced via the self-sacrificing MOF template methods. However, this strategy is high-energy consuming, and it is difficult to precisely control the structure and component homogeneity of the product during pyrolysis.

3D printing has changed the world. It's allowed the aerospace, medical, automotive, manufacturing and many other industries to customize parts and prototypes in ways they never could before. It has drastically increased flexibility and cost effectiveness while reducing waste and production time. But many 3D-printed materials aren't the strongest.

Harnessing the ability of wood products to store carbon even after harvest could have a significant effect on greenhouse gas emissions and change commonly accepted forestry practices, a new study from NC State researchers suggests.

An Institute for Systems Biology (ISB)-led study has unveiled important insights and actionable protocols into providing equitable STEM (Science, Technology, Engineering, and Mathematics) experiences for high school students from historically marginalized communities. The research highlights the transformative power of informal STEM learning in addressing societal challenges and the ease with which many organizations could provide these important opportunities.

Don't worry if an employee reacts poorly to negative feedback. It doesn't necessarily mean they will perform poorly on subsequent work, according to research from Virginia Commonwealth University.

Soil carbon is exactly what it sounds like: carbon collected and stored in soil. Plants pull carbon from the atmosphere during photosynthesis and deposit it into the soil as their leaves, stems, and roots decompose. In fact, soil contains more than three times as much carbon as the atmosphere.

The dramatic expansion of Internet communication tools has led to increases in temporary online groups that solve problems, provide services, or produce new knowledge. But many of these groups struggle to collaborate effectively.

In an era where social media platforms have become battlegrounds for information integrity, a new study sheds light on the mechanics of disinformation spread and offers innovative solutions to counteract it.

How extreme weather and climate events change is an intriguing issue in the context of global warming. As IPCC AR6 points out, cold extremes have become less frequent and less severe since the 1950s, mainly driven by human-induced climate change. However, cold extremes could also exhibit robust interdecadal changes at regional scale.

Some of us used to imagine a world where the morning commute was a short stroll from your bedroom, the dress code included comfy slippers, and the closest coffee shop was your kitchen. Then working from home became a reality for many during the COVID pandemic, reshaping our work-life balance.

Scientists very rarely get access to most sharks, the development of their young or the nursery grounds where they grow. So seeing a hammerhead shark (Sphyrna tiburo) embryo, halfway through its five-month development, is very unusual.

"They knew we had separated. Why did they let him cancel the policy and refund him the money without giving me a call to let me know the house and contents were no longer insured, or not do it before speaking to me first?"

In the summer of 2008, during a family holiday road trip, we passed by the Aquitaine region in southwestern France. As we drove through a sprawling woodland, a mesmerizing sight unfolded before my eyes: a meticulously ordered army of trees, standing tall and proud. It could have been an army regiment classified by age.

Wildlife trade affects all kinds of species, from insects and fungi to large plants and mammals. The global trade of numerous species poses a significant threat to their survival, increasing their risk of extinction.

NASA's Artemis program is scheduled to return astronauts to the moon and establish a permanent orbiting laboratory by the end of the decade.

You're probably familiar with classic sauropod dinosaurs—the four-legged herbivores famous for their long necks and tails. Animals such as Brachiosaurus, Apatosaurus and Diplodocus have been standard fixtures in science museums since the 1800s.

The Great Southern Australian Coastal Upwelling System is an upward current of water over vast distances along Australia's southern coast. It brings nutrients from deeper waters to the surface. This nutrient-rich water supports a rich ecosystem that attracts iconic species like the southern bluefin tuna (Thunnus maccoyii) and blue whale (Balaenoptera musculus brevicauda).

Chefs are in hot demand. "Chefs, chefs, chefs! Virtually impossible to find anyone," lamented one Auckland restaurant owner recently. Australia is seeing a similar gap, with chefs ranked the eighth most in-demand occupation. Given this culinary skills shortage, we might expect such sought-after employees to be highly valued.

Public interest journalism was already under significant stress in Australia. And now the pressure is ratcheting up even further.

New Zealand's justice system is failing. The country has one of the highest rates of incarceration in the OECD, and over 56% of people with prior convictions are reconvicted within two years.
