Tracing changes to the human diet during the transition from hunting to agriculture
A large team of researchers affiliated with a host of institutions across Italy has used DNA found in the dental calculus of ancient peoples to help trace changes to the human diet during the transition from hunting to agriculture in Italy over thous.....»»
What are nanoplastics? An engineer explains concerns about particles too small to see
It's become common to read that microplastics—little bits of plastic, smaller than a pencil eraser—are turning up everywhere and in everything, including the ocean, farmland, food and human bodies. Now a new term is gaining attention: nanoplastic.....»»
Study identifies early warning signals for the end of the African humid period
The transition from the African humid period (AHP) to dry conditions in North Africa is the clearest example of climate tipping points in recent geological history. They occur when small perturbations trigger a large, non-linear response in the syste.....»»
Laboratory and natural strains of intestinal bacterium turn out to have similar mutational profiles
Understanding mutational processes in a cell offers clues to the evolution of a genome. Most actively, mutation processes are studied in human cancer cells, while other genomes are often neglected......»»
Researchers explain how following the dietary guidelines is smart—for you and the climate
For the first time, Norwegian researchers have calculated what effect the average Norwegian diet has on the climate and environment and have studied the potential benefits for the climate and environment if we start following a diet in line with exis.....»»
Self-adaptive system for temperature control: A dynamically controllable strategy for healing wound tissue
Skin functions as a sophisticated sensorial system in the human body, capable not only of detecting environmental stimuli—such as temperature, pressure, strain, and vibration—but also of actively responding to these changes. Among these, the temp.....»»
Debates on campus safety in response to Palestine solidarity activism show we need strategies to navigate discomfort
Canada's House of Commons Standing Committee on Justice and Human Rights will soon begin hearings on antisemitism and Islamophobia. The process comes partly in response to claims that university and college campuses are unsafe spaces......»»
How "apocalypse" became a secular as well as religious idea
The exponential growth of artificial intelligence over the past year has sparked discussions about whether the era of human domination of our planet is drawing to a close. The most dire predictions claim that the machines will take over within five t.....»»
Saturday Citations: Parrots on the internet; a map of human wakefulness; the most useless rare-earth element

Aligned peptide "noodles" could enable lab-grown biological tissues
A team of chemists and bioengineers at Rice University and the University of Houston have achieved a significant milestone in their work to create a biomaterial that can be used to grow biological tissues outside the human body......»»
NASA is helping protect tigers, jaguars, and elephants—here"s how
As human populations grow, habitat loss threatens many creatures. Mapping wildlife habitat using satellites is a rapidly expanding area of ecology, and NASA satellites play a crucial role in these efforts. Tigers, jaguars, and elephants are a few of.....»»
Human activity is causing toxic thallium to enter the Baltic Sea, finds new study
Human activities account for a substantial amount—anywhere from 20% to more than 60%—of toxic thallium that has entered the Baltic Sea over the past 80 years, according to new research by scientists affiliated with the Woods Hole Oceanographic In.....»»
Study finds human noise negatively impacts cricket survival and reproduction
As the sun sets and the sweltering heat gives way to a balmy evening, there's one sound that fills the air, both beloved and bothersome: the rhythmic symphony of chirping crickets. However, human-generated noise can mask the harmony of the cricket so.....»»
The COVID-19 pandemic changed our patterns and behaviors, which in turn affected wildlife
The Earth now supports over eight billion people who collectively have transformed three-quarters of the planet's land surface for food, energy, shelter and other aspects of the human enterprise......»»
Bioreactor processes and cryotechnologies improve active ingredient tests using human cell cultures
Many new drug candidates end up failing because they cause serious side effects in clinical trials even though lab tests involving cell cultures have been successful. This is a common occurrence if the cells used come from animal tissue, for example......»»
Deeper understanding of malaria parasite sexual development unlocks opportunities to block disease spread
For the first time, the developmental stages of the deadliest human malaria parasite have been mapped in high resolution, allowing researchers to understand this ever-adapting adversary in more detail than previously possible......»»
