Climate scientist: Broken temperature records are alarming, but it is not too late to limit global warming
July 22, 2024 was the hottest day in recorded human history, with a global average temperature of 17.16 C......»»
Domesticating horses had a huge impact on human society—new science rewrites where and when it first happened
Across human history, no single animal has had a deeper impact on human societies than the horse. But when and how people domesticated horses has been an ongoing scientific mystery......»»
Beef industry can reduce emissions by up to 30%, says new research
Greenhouse gases resulting from human activity have been the largest driver of climate change since the mid-20th century—especially from agriculture. The U.S. beef industry alone is responsible for 3.3% of the nation's total emissions, and even wit.....»»
Whole genome duplications linked to higher oil yields in key crops
Oil crops are pivotal for human nutrition and industry due to their ability to produce and store large amounts of oil in seeds. With the global demand for vegetable oils steadily rising, there is an urgent need to discover new high-yielding oil plant.....»»
The right to be wrong: How context or human rationality may influence our decisions
Conventionally, decision-making is portrayed as a rational process: individuals calculate potential risks and aim to maximize benefits. Yet, our brains do not always endorse rational action, particularly when an immediate response is required. Someti.....»»
Wild and human-cared spotted dolphins harbor different gastrointestinal microbiomes, researchers find
A recent study published in Water Biology and Security highlighted the significant role of food source variations in shaping the gut microbiome of spotted dolphins, even when they inhabit similar environments......»»
Mass cytometry barcoding strategy offers a new perspective of non-specific binding
Non-specific binding (NSB), the most annoying thing to scientists in the biosensing field, is one of the main factors limiting the performance of diagnostic sensors......»»
Simulation study explores how gift giving drives social change
New findings provide quantitative criteria for classifying social organizations in human history, together with potential explanatory variables that can be empirically measured for anthropology, history and archaeology, according to a study published.....»»

Are you interested in AI? Do you enjoy science fiction? Do you have an opinion about how AI will impact the human species? Are you enthusiastic about it or worried about it? Or do you think you know the answer? Dave Jilk (my first business partner an.....»»
Human mouth bacteria reproduce through rare form of cell division, research reveals
One of the most diverse ecosystems on the planet is closer than you think—right inside your mouth. Your mouth is a thriving ecosystem of more than 500 different species of bacteria living in distinct, structured communities called biofilms. Nearly.....»»
Study suggests gun-free zones do not attract mass shootings
Gun-free zones have often been blamed for making schools, malls and other public areas more attractive to shooters; however, there have been no quantitative studies examining those claims. Now, in a first of its kind study published in The Lancet Reg.....»»
Replica symmetry breaking in 1D Rayleigh scattering system: Theory and validations
In both the natural world and human society, there commonly exist complex systems, such as climate systems, ecological systems, and network systems. Due to the involvement of numerous interacting elements, complex systems can stay in multiple differe.....»»
Gravitational wave observatories could detect primordial black holes speeding through the solar system
Cosmologists have long hypothesized that the conditions of the early universe could have caused the formation of black holes not long after the Big Bang. These "primordial black holes" have a much wider mass range than those that formed in the later.....»»
Double-peaked supernovae offer clues to pre-supernova outbursts
New research helps in understanding the evolution and final stages of massive stars, the role of binary interactions, and the mechanisms behind mass loss, which ultimately affect the properties of the resulting supernova and its remnant. This work al.....»»
Webb discovers six new "rogue worlds" that provide clues to star formation
Rogue planets, or free-floating planetary-mass objects (FFPMOs), are planet-sized objects that either formed in interstellar space or were part of a planetary system before gravitational perturbations kicked them out......»»
Understanding how human activity impacts zooplankton is essential for managing and protecting lakewater
Freshwater ecosystems are impacted by human activities, including climate change, pollution and invasive species......»»
Investigation reveals global fisheries are in far worse shape than we thought—and many have already collapsed
When fish are taken from our oceans faster than they can reproduce, their population numbers decline. This over-fishing upsets marine ecosystems. It's also bad for human populations that rely on fish for protein in their diets......»»
Archaeologists discover diseased Anglo-Saxons that received monastic care
An additional 20 intact human burials and the disturbed remains of many more have been discovered by archaeologists excavating a monastery in Cookham......»»
Research highlights drought risk and awareness gaps in global society
Natural disasters have threatened human beings and the ecosystem. Among the various natural disasters, drought is one of the most insidious and costliest, adversely affecting the global economy and livelihoods. Unlike sudden disasters such as earthqu.....»»
