A new telescope called the "Condor Array Telescope" may open up a new world of the very-low-brightness universe for astrophysicists. Four new papers, published back to back in the Monthly Notices of the Royal Astronomical Society (MNRAS) this month, present the first scientific findings based on observations acquired by Condor. The project is a collaborative led by scientists in the Department of Physics and Astronomy at Stony Brook University and the American Museum of Natural History (AMNH).

Encompassing over 16,000 km2 of towering mountains, long fiords, lush valleys, and massive ice caps, Agguttinni Territorial Park is a protected area on northern Baffin Island, Nunavut, Canada. This park, and all of Nunavut, is Inuit Nunangat—Inuit homeland in Canada—and the park protects sites and biodiversity stewarded by Inuit since time immemorial.

Supporting kids with math homework is a common afterschool activity. But beyond the basics, new curricula and teaching strategies are making it harder for parents to help and it's taking a serious toll on children's confidence and learning.

This colorful web of wispy gas filaments is the Vela Supernova Remnant, an expanding nebula of cosmic debris left over from a massive star that exploded about 11,000 years ago. Located around 800 light-years away in the constellation Vela (the Sails), this nebula is one of the nearest supernova remnants to Earth. Though the unnamed star ended its life thousands of years ago, the shockwave its death produced is still propagating into the interstellar medium, carrying glowing tendrils of gas with it.

An international team of paleontologists from The Netherlands, the UK, Argentina, Germany and Belgium applied recently developed methods to measure theropod (carnivorous) dinosaur species diversity. The newly applied method uses both traditional phylogenetic analysis, discriminant analysis as well as machine learning.

The collapse of the former Soviet Union in 1991 yielded social, political and economic effects worldwide. Among them was a suspected role in slowing human-generated methane emissions. Methane had been rising steadily in the atmosphere until about 1990. Atmospheric scientists theorized that economic collapse in the former USSR led to less oil and gas production, and thus a slowdown in the rise of global methane levels, which has since resumed.

Some Americans believe that undocumented immigrants are a criminal threat to society. Former President Donald J. Trump has leveraged this assumption to inflame the rhetoric around immigration from the U.S.-Mexico border.

New research co-led by Simon Fraser University and the National Archaeological Anthropological Memory Management (NAAM Foundation) in Curaçao extends the earliest known human settlement of Curaçao by centuries, adding pieces to the puzzle of pre-Colombian Caribbean history.

Research in quantum materials is paving the way for groundbreaking discoveries and is poised to drive technological advancements that will redefine the landscapes of industries like mining, energy, transportation, and medtech.

New research highlights the conflict between the needs of a team and the needs of the individuals in the team—and what leaders can do to strike the right balance to keep things ticking smoothly.

The Hudson River Eel Project—which has netted, counted and released roughly 2 million juvenile eels since its inception in 2008—owes its success to a cadre of nearly 1,000 high school, college and adult citizen scientists donating time and effort each spring along the Hudson River.

Gun manufacturers are appealing to women as "serious students" of firearms in their advertising—a shift in strategy over the last two decades that may be contributing to increased gun sales, a new study shows.

Numerous measurement stations around the world provide us with data about air quality, allowing us to enhance it. Although we are increasingly collecting data from marine areas, access to such data is considerably more challenging. Signals are poorly transmitted through water, differences in both pressure and currents hinder measurement devices and there is an absence of pre-constructed computing infrastructure.

How can we encourage consumers to pay more attention to animal welfare aspects when they purchase meat? It now appears that this cannot be achieved solely by making the animal husbandry labels more visible. At least, this is what the findings of a study carried out by the University of Bonn and TU Munich tend to indicate. In this study, the researchers invited test subjects to go shopping in a virtual supermarket.

A study in the International Journal of Business Excellence examining the relationship between gender diversity on corporate boards and corporate social responsibility spending has found a positive correlation. The research focused on 738 firms across India listed on the national stock exchange over a seven-year period.

Safety issues related to flammable electrolytes in lithium-ion batteries (LIBs) remain a major challenge for their extended application. The use of non-flammable phosphate−based electrolytes has proven its validity in inhibiting the combustion of LIBs. However, the strong interaction between Li+ and phosphate leads to a dominant solid electrolyte interphase (SEI) with limited electronic shielding, resulting in poor Li+ intercalation at the graphite (Gr) anode when using high−phosphate−content electrolytes.

Smart materials that can rapidly respond to external stimuli possess immense potential for applications in anti-counterfeiting and encryption, data storage, sensors, bioimaging, and so on. However, most stimulus-responsive systems are designed based on controlled fluorescence emission (emission color and intensity).

I am a conservation biologist who studies emerging infectious diseases. When people ask me what I think the next pandemic will be I often say that we are in the midst of one—it's just afflicting a great many species more than ours.

A new study identifies ten key components that will promote the development and implementation of sustainable, equitable, climate-smart ocean planning initiatives around the globe.

Scientists know relatively little about particles released into the air when a vehicle driver brakes, though evidence suggests that those particles may be more harmful to health than particles exiting the tailpipe.

Waste pollution is a huge problem in Nigeria, with serious impacts on the environment. In response, the Lagos state government has banned styrofoam (a type of plastic widely used as food containers) and other single-use products.

Tradeoffs and synergies between ecosystem services constitute an important topic in ecosystem management. The value of each service is substantially influenced by human activities, and changes will affect human decisions. Given the variability in tradeoffs and synergies, the simultaneous optimization of multiple ecosystem services presents a considerable challenge.

I recently watched NESC Deputy Director Mike Kirsch stand before a roomful of engineers at the Langley Research Center and tell them that with every passing day, NASA breaks a record: the longest stretch without a major accident in the nation's human spaceflight program since the Space Shuttle Columbia disintegrated during reentry on February 1, 2003. NASA's challenge, he told them, was to make sure the record keeps being broken.

As China rapidly urbanizes, turning waste into energy has become a key way to handle growing trash volumes and reduce landfill use, while also creating power. Yet, concerns about the pollution from these plants and its health effects have led to debates. Making sure these plants use the best technology to control pollution is crucial for protecting air quality and health, emphasizing the need for ongoing improvements and careful health checks.

Aesthetic attraction plays a big role in orangutans' mate choice, behavioral biologist and Ph.D. candidate Tom Roth has observed. But to discover just how big that role is, more research is needed into the emotions of the great apes.
