The UK pedigree dog population shrank by a yearly decline of 0.9% between 1990 and 2021, according to research published in Companion Animal Genetics and Health. The study highlights a rise in the populations of crossbreeds and imported pedigree dogs since 1990, but finds that only 13.7% of registered domestic pedigree dogs were used for breeding between 2005 and 2015.

Climate change may significantly impact arsenic levels in paddy rice, a staple food for millions across Asia, reveals a new study from Columbia University's Mailman School of Public Health. The research shows that increased temperatures above 2°C, coupled with rising carbon dioxide (CO2) levels, lead to higher concentrations of inorganic arsenic (iAs) in rice, potentially raising lifetime health risks for populations in Asia by 2050.

A new study by researchers at ProtectedSeas highlights the potential of marine radar technology to monitor speed of small vessels. The research, aimed at testing the accuracy of radar in assessing potential violations, found that the technology could detect speed violations with 95% confidence, offering a promising solution to help reduce the threat of vessel strikes on whale populations. The analysis was recently published in the journal Sensors.

Many bird species are monogamous. However, genetic studies have shown that the social partner is often not the genetic father of all offspring. Some studies found biased sex ratios: more males than females among extra-pair fledglings.

The pedunculate oaks typical of Leipzig's floodplain forest and other German oak forests are struggling to regenerate in the understory due to a lack of light. One reason for this is the absence of flooding in floodplain forests.

Plants store carbon in two primary forms: starch and triacylglycerols (TAGs). Starch is mainly stored in chloroplasts in leaves, where it serves as a readily available energy source, while TAGs are stored in seeds for long-term energy storage. Past studies have shown that a carbon trade-off exists between these two storage forms, implying that an increase in the levels of one form often reduces the levels of the other.

Lysosomes are membrane-bound organelles in cells that act as recycling centers—breaking down waste materials, damaged organelles, and unwanted molecules using powerful digestive enzymes. Lysosomes play a vital role in maintaining cellular health by clearing debris and supporting processes like autophagy.

Five chicks of the critically endangered Brazilian merganser have been born at the Prague Zoo, fueling hopes for a reintroduction of the duck in the wild, a breeder said Wednesday.

Risky human behavior, not aggression by alligators, is the leading cause of alligator bites, according to a study by scientists at the University of Florida and Center College in Kentucky.

Aquatic foods are vital to Malaysia's food security, nutrition, economy, and livelihoods—with both capture fisheries and aquaculture playing central roles. However, the sector is currently at a critical juncture. A new study shows that despite its critical role, capture fisheries has stalled while farmed fish and seaweed are now driving growth.

Over half of vessels operating in Scotland's coastal waters are effectively "invisible" to standard maritime tracking systems, according to a new Heriot-Watt study.

Since time immemorial, plants and arbuscular mycorrhizal fungi have coexisted in a mutually beneficial relationship. The fungi colonize plant roots and help them absorb nutrients. In return, plants provide the fungi with the carbon they need.

Scientists have uncovered new details about cellular filaments that play a critical role in wound healing, according to a study published in the Proceedings of the National Academy of Sciences.

Using advanced DNA sequence analysis, a research team has discovered that tiny organisms in Brooklyn's highly contaminated Gowanus Canal have developed a comprehensive collection of pollution-fighting genes. This finding suggests the potential of a cheaper, more sustainable, and less disruptive method for cleaning contaminated waterways than the current oft-used dredging operations.

A recently published paper reveals that soil scratching by gorillas in Congo's Nouabalé-Ndoki National Park is a foraging strategy to access a species of deer truffle, identified as Elaphomyces labyrinthinus, and not insects, as long assumed.

An international team of scientists and crew on board Schmidt Ocean Institute's research vessel Falkor (too) was the first to film the colossal squid (Mesonychoteuthis hamiltoni) in its natural environment. The 30-centimeter juvenile squid (nearly one foot long) was captured on video at a depth of 600 meters (1968 feet) by the Institute's remotely operated vehicle (ROV) SuBastian. The sighting occurred on March 9 on an expedition near the South Sandwich Islands in the South Atlantic Ocean.

Potatoes are a staple food for over 1.3 billion people. But despite their importance for global food security, breeding successes have been modest. Some of the most popular potato cultivars were bred many decades ago. The reason for this limited success is the complex genome of the potato: there are four copies of the genome in each cell instead of just two. This challenges traditional hybridization-based breeding.
