What is the role of artificial intelligence for crop improvement? Questions about artificial intelligence are becoming more pressing in every discipline. For crop improvement, AI provides a new lens to bridge science and practice, according to Jianming Yu, one of the world's top-ranked scientists in the fields of quantitative genetics and plant breeding.

The responsibility for maintaining online safety relies on content moderators particularly in times of crisis. However, not all platforms even have moderation systems in place and so disinformation, misinformation, propaganda, and fake news often circulate freely.

Scientists at a United Nations conference in Spain called Friday for more research into the sharp rise in ocean temperatures which they warn could have devastating consequences.

In the constellation Virgo, 700 light years away from Earth, the planet WASP-39b orbits the star WASP-39. The gas giant, which takes little more than four days to complete one orbit, is one of the best-studied exoplanets. Shortly after its commissioning in July 2022, NASA's James Webb Space Telescope turned its high-precision gaze on the distant planet.

In cellular biology, unraveling the complexities of cellular function at the molecular level remains a paramount endeavor. Significant scientific focus has been placed on understanding the interactions at organelle contact sites, especially between mitochondria and the endoplasmic reticulum (ER). These sites are critical hubs for the exchange of essential biomolecules, such as lipids and calcium, which are vital for maintaining cellular homeostasis.

During the Apollo missions of the 1970s, several seismometers were flown to the moon, where they collected data on lunar seismic trembling for eight years. The data showed some lunar quakes were as powerful as a magnitude 5.

Scientists previously believed that a family of flowering plants called yellow-eyed grasses didn't attract many insect visitors, but the recent discovery of a fungus that hijacks the plant and forms fungal "pseudoflowers" has researchers rethinking this assumption.

SpaceX has significantly increased the frequency of its rocket launches from a Santa Barbara County military base, and its plans to add even more have raised concerns by the California Coastal Commission over the impacts on the environment and nearby communities.

Toothpaste tubes and other squeezable plastic containers are getting closer to being more sustainable in the U.S. Some 90% of toothpaste tubes on the market are now made in a way that makes them compatible for recycling with HDPE, the same plastic used for products like shampoo bottles, according to research firm Stina Inc.

Chimpanzees and bonobos are often thought to reflect two different sides of human nature—the conflict-ready chimpanzee versus the peaceful bonobo—but a new study published in Current Biology shows that, within their own communities, male bonobos are more frequently aggressive than male chimpanzees. For both species, more aggressive males had more mating opportunities.

It is one of the world's most spectacular sights—huge flocks or "flamboyances" of flamingos around East Africa's lakes—as seen in the film "Out of Africa" or David Attenborough's "A Perfect Planet."

A deep dive into macroalgae genetics has uncovered the genetic underpinnings that enabled macroalgae, or "seaweed," to evolve multicellularity. Three lineages of macroalgae developed multicellularity independently and during very different time periods by acquiring genes that enable cell adhesion, extracellular matrix formation, and cell differentiation, researchers report in the journal Molecular Plant.

Compulsory income management (CIM) in the Northern Territory is perceived to be ineffective in reducing harm, can contribute to situations of family violence and is incompatible with the needs of welfare recipients, a new study led by Charles Darwin University (CDU) has found.

Water levels at Lake Kariba in Zimbabwe have dropped dramatically because of the latest El Niño drought. The country's president, Emmerson Mnangagwa, has declared a national disaster.

Aboriginal and Torres Strait Islander readers are advised this article may contain images of deceased people. It contains mentions of the Stolen Generations, and policies using outdated and potentially offensive terminology when referring to First Nations people.

Australia's weather bureau copped harsh criticism after El Niño failed to deliver a much-vaunted dry summer in eastern Australia. Parts of northern Queensland in the path of Tropical Cyclone Jasper had a record wet December and areas of central Victoria had a record wet January. Overall, the summer was 19% wetter than average for Australia as a whole.

By analyzing the data from ESA's Gaia satellite, Chinese astronomers have detected a new tidal stellar stream in the northern hemisphere, which has a low metallicity and a relatively high energy. The finding was reported in a research paper published April 1 in The Astrophysical Journal.

The BESIII collaboration have reported the observation of an anomalous line shape around ppbar mass threshold in the J/ψ→γ3(π+π-) decay, which indicates the existence of a ppbar bound state. The paper was published online in Physical Review Letters.

The world ends on Oct. 23, 2077, in a series of radioactive explosions—at least in the world of "Fallout," a post-apocalyptic video game series that has now been adapted into a blockbuster TV show on Amazon's Prime Video.

A Northwestern Medicine study has detailed the development of a machine learning model to predict DNA methylation status in cell-free DNA by its fragmentation patterns, according to findings published in Nature Communications.

Microplastics pose a great threat to human health. These tiny plastic debris can enter our bodies through the water we drink and increase the risk of illnesses. They are also an environmental hazard; found even in remote areas like polar ice caps and deep ocean trenches, they endanger aquatic and terrestrial lifeforms.

Mother Nature is an artist, but her craft of creating animal faces requires more than a paintbrush and palette. Such highly complex shapes originate from their respective transient neural crest cells.

April showers are increasingly becoming deluges due to climate change, and May flowers will never be the same. And it's not just April; the warming of the planet is causing a year-round, worldwide trend toward more intense but less frequent rainfalls, a dynamic that will increasingly impact plants worldwide, according to a University of Maryland-led study published in Nature Reviews Earth & Environment.

New research led by oceanographers from the School of Ocean Sciences at Bangor University has shown for the first time the important role of the 'mixing down' of oxygen in maintaining healthy conditions in the deep waters around the UK and elsewhere.

Researchers have developed a novel microfluidic chip with capacitively coupled contactless conductivity detection (C4D) integrated 3D microelectrodes to rapidly and quantitatively determine abundant nutrient ions in soil.
