Genes are switched on in the human embryo from the get-go
The finding that some genes are active from the get-go challenges the textbook view that genes don't become active in human embryos until they are made up of four-to-eight cells, two or three days after fertilization......»»
Physicists and psychologists track social phases in human movement
Observations of preschool children in classrooms and playgrounds have uncovered new social phases in human movement. Employing ultra-wideband radio frequency identification (UWB-RFID) technology allows for the precise tracking of children's movements.....»»
Nobel Prize in medicine awarded for discovery of microRNAs, the molecules that control our genes
Two scientists, Victor Ambros (UMASS Chan Medical School in the US) and Gary Ruvkun (Harvard Medical School in the US), have won the 2024 Nobel prize in medicine or physiology......»»
Medicine Nobel goes to previously unknown way of controlling genes
MicroRNAs control the activity of many key genes but were unknown before 1993. On Monday, the Nobel Committee announced that two US researchers, Victor Ambros and Gary Ruvkun, wil.....»»
Study of global primate populations reveals predictors of extinction risk
An international team of biologists, planetary scientists and conservationists has conducted a large-scale study of non-human primate populations around the world to gauge their risk of extinction due to climate change......»»
The more sophisticated AI models get, the more likely they are to lie
Human feedback training may incentivize providing any answer—even wrong ones. When a research team led by Amrit Kirpalani, a medical educator at Western University in Ontario, C.....»»
What"s the best material for a lunar tower?
Physical infrastructure on the moon will be critical to any long-term human presence there as both America and China gear up for a sustained human lunar presence. Increasingly, a self-deploying tower is one of the most essential parts of that physica.....»»
Human cases of H5N1 confirmed in California amid rapid dairy spread

As bird flu rages through California cows, possible human case identified
If the case is confirmed by the CDC, it will be the 16th linked to the dairy outbreak. A California dairy farm worker who had contact with H5N1-infected cows appears to have contr.....»»
NASA is working on a plan to replace its space station, but time is running out
"Initially, Congress almost treated the program as a joke." The next year is crucial for the future of NASA and its plans to extend human activity in low-Earth orbit. For the firs.....»»
Ants learned to farm fungi during a mass extinction
Ants learned to work with fungi back in a world where only fungi could thrive. We tend to think of agriculture as a human innovation. But insects beat us to it by millions of year.....»»
Study identifies compounds that extend longevity of Japanese morning glory flowers
The longevity of plant flowers is controlled by genetically programmed mechanisms. After a certain amount of time after flowering, the expression of genes associated with programmed cell death is induced and cellular components such as proteins and n.....»»
The darker side of human rights for great apes
The Spanish government has announced plans to ban harmful experiments on great apes as part of a wider initiative to give them increased rights closer to the ones humans enjoy......»»
Scientists find plant-like behavior in human cells
A team of scientists from Monash University has solved the structure of a protein known as "LYCHOS," which can detect and regulate cell growth by sensing cholesterol levels in the body......»»
Climate change is causing algal blooms in Lake Superior for the first time in history
Lake Superior is known for its pristine waters, but a combination of nutrient additions from increasing human activity (including farming and development), warming temperatures and stormy conditions have resulted in more frequent blooms of potentiall.....»»
AI-generated college admissions essays tend to sound male and privileged, study finds
In an examination of thousands of human-written college admissions essays and those generated by AI, researchers found that the AI-generated essays are most similar to essays authored by students who are males, with higher socioeconomic status and hi.....»»
NASA powers down Voyager 2 plasma instrument to extend mission
To save power, NASA has switched off another scientific instrument on its long-running Voyager 2 spacecraft......»»
Loyalty influences support for indirect ties in moral dilemmas, study finds
In the complex network of human relationships, choosing to show allegiance to someone often shapes decisions and actions. But what happens when loyalty to one friend extends to their connections?.....»»
The Vagus Nerve’s Crucial Role in Creating the Human Sense of Mind
