Cold stratification impacts germination rates in Vitis species
It is imperative for the success of the grape industry to develop new grape varieties capable of enduring shifting climates and heightened pressures from diseases and insects. The majority of grape cultivars rely on a specific amount of "chilling ho.....»»
Researchers call for harnessing agrifood value chains to help farmers be climate-smart
The global food system is uniquely vulnerable to climate impacts, making adaptation of paramount importance. While contributing roughly one-third of total anthropogenic emissions, food systems around the world fortunately also hold immense potential.....»»
3D fossil scans investigate the origins of bipedal locomotion in human evolution
One of the most fascinating periods in the evolution of the human lineage is the appearance of the first ancestors capable of bipedalism. Knowing the type of locomotion used by many fossil species—walking upright on the ground or climbing from bran.....»»
Genetic factors in woodland strawberries promote cold tolerance
Climate change is shifting the seasons, pushing crop plants to their limits. For example, sudden frost episodes in late spring can be detrimental to strawberries in the bed. Wild species, on the other hand, are often more resilient......»»
Fossilized footprints reveal two extinct hominin species living side by side 1.5 million years ago
Human footprints stir the imagination. They invite you to follow, to guess what someone was doing and where they were going. Fossilized footprints preserved in rock do the same—they record instances in the lives of many different extinct organisms,.....»»
A fossil first: Scientists find 1.5-million-year-old footprints of two different species of human ancestors at same spot
More than a million years ago, on a hot savanna teeming with wildlife near the shore of what would someday become Lake Turkana in Kenya, two completely different species of hominins may have passed each other as they scavenged for food......»»
Biologists identify traits correlating with all bird extinctions since 1500
Looking to inform the conservation of critically endangered bird species, University of Utah biologists have completed an analysis identifying traits that correlate with all 216 bird extinctions since 1500......»»
Scientists use acoustic data to track blue and fin whale occurrences in the Arctic
The long-term analysis of blue whale and fin whale vocalizations in the eastern Fram Strait offers valuable insights into seasonal and annual patterns regarding these species' occurrence in the region. For example, blue whales can primarily be heard.....»»
Brains grew faster as humans evolved, study finds
Modern humans, Neanderthals, and other recent relatives on our human family tree evolved bigger brains much more rapidly than earlier species, a new study of human brain evolution has found......»»
Marine heat waves" hidden depths revealed in study
As the ocean warms under climate change, a better understanding of how damaging marine heat waves develop and last may help scientists predict them more accurately and forecast their impacts on marine ecosystems......»»
Maritime pine seeds remember temperature conditions
The seeds of maritime pines remember the temperatures they experienced during early development. This memory persists in young trees for at least two years after germination. The above discovery was made by researchers at INRAE, CEA, FCBA, the Univer.....»»
X-ray measurements reveal an unexpected role for copper in photocatalysts
Copper is a promising catalyst for sustainably converting carbon dioxide into substances with more electrons (called reduced species). This is an important step in converting carbon dioxide into fuels. This reaction is often initiated by electrical e.....»»
Mathematicians develop AI to forecast market interest rates
Researchers from the Ateneo de Manila University have developed artificial intelligence (AI) deep learning tools that can help predict money market interest rates, invaluable for decision-makers in business and government......»»
First right whales of season gorge on critical food off Massachusetts, giving hope for a strong year
Scientists who study a critically endangered species of whale that lives off New England said encouraging early signs suggest the animals could have a strong season for feeding and breeding......»»
New AI tool generates realistic satellite images of future flooding
Visualizing the potential impacts of a hurricane on people's homes before it hits can help residents prepare and decide whether to evacuate. MIT scientists have developed a method that generates satellite imagery from the future to depict how a regio.....»»
Australia in a baby bust? It"s not that simple—and a panic won"t help
There is a seemingly endless stream of news headlines about plummeting birth rates. Many have alarmist narratives about the perils of "baby busts" and "population decline." This reflects a deep-seated anxiety about what declining birth rates mean for.....»»
Study discovers formation of Criegee intermediates from photochemical oxidation of alkenes
Organic peroxy radicals (RO2) and Criegee intermediates (CI, carbonyl oxides) are key reactive species in atmospheric chemistry and play crucial roles in the formation of secondary organic aerosol (SOA)......»»
International team studies the migration of the American woodcock
The American woodcock, a plump harbinger of spring, is a well known shorebird found across eastern North America. The species is a popular game bird and has earned the admiration of hunters, birders and others through its spring display, whistling wi.....»»
Slender-billed Curlew may be extinct, marking the disappearance of a third bird species from the Western Palaearctic
A small team of conservationists, biodiversity specialists and bird researchers has found that it is likely a third species of bird has gone extinct in the Western Palaearctic—a large area of land spanning parts of North Africa all the way up to po.....»»
New tools filter noise from evolution data
While rates of evolution have appeared to accelerate over short time periods, new analysis suggests that statistical noise is affecting the data patterns. A professor at the University of Tennessee, Knoxville, and his colleague have developed new too.....»»
Russian ballistic missile attack on Ukraine portends new era of warfare
This is the first time an IRBM, once restricted by a Cold War arms treaty, has been used in combat. Two days ago, Russian President Vladimir Putin announced a change in the countr.....»»
