We may have parted ways with our primate cousins millions of years ago, but a new study shows just how human beings continue to evolve...

Analysis - That humans originated in Africa is widely accepted. But it's not generally recognised how unique features of Africa's ecology were responsible for the crucial evolutionary transitions from forest-inhabiting fruit-eater to savanna-dwelling hunter. …

In the absence of transcription, gene expression required for oocyte maturation is regulated by translation of preexisting mRNAs. Here the authors show that a defective program of mRNA translation in oocyte is associated with maternal aging.

The rotation of Earth's inner core may have paused and it could even go into reverse, new research suggests.

China's APSTAR-6E telecommunication satellite has recently separated from its independent propulsion module, beginning its electrically propelled orbit change journey, according to the China Aerospace Science and Technology Corporation (CASC), the satellite's…

NASA Administrator Bill Nelson said Tuesday that the US space agency will team up with the Defense Advanced Research Projects Agency (DARPA) to "develop and demonstrate advanced nuclear thermal propulsion technology as soon as 2027."

NASA officials view nuclear thermal propulsion as crucial for sending humans beyond the moon and deeper into space.

[Hank Green] posted an interesting video about the first liquid mirror telescope from back in the 1850s. At the time, scientists were not impressed. But, these days, people are revisiting the idea.…

Fertilization is the union of two cells: an egg and a sperm. Before the egg and the sperm fuse, an event known as the "acrosome reaction" needs to occur in the sperm.

Water correctly and add nitrogen in the right amount, and you'll not only increase yields, you'll also reduce nitrogen leaching from your fields. That's the recipe from researchers at Aarhus University.

According to the Danish Parliament's "Agreement on the Green Transformation of Danish Agriculture", agriculture must contribute significantly to achieving the goal of reducing greenhouse gas emissions by 70% by 2030 compared to 1990 levels. An increase in the…

In their new paper for the Geological Society of America journal Geology, Dulcinea Groff and colleagues used radiocarbon ages (kill dates) of previously ice-entombed dead black mosses to reveal that glaciers advanced during three distinct phases in the northe…

NASA’s Lucy spacecraft will add another asteroid encounter to its 4-billion-mile journey. On Nov. 1, 2023, the Southwest Research Institute-led Lucy mission will get a close-up view of a small main belt asteroid to conduct an engineering test of the spacecraf…

Engineers at Tokyo Institute of Technology have demonstrated a simple computational approach for supporting the classification performance of neural networks operating on sensor time series. The proposed technique involves feeding the recorded signal as an ex…

In an observational feat of high precision, scientists used a new technique with NASA’s James Webb Space Telescope to capture the shadows of starlight cast by the thin rings of Chariklo. Chariklo is an icy, small body, but the largest of the known Centaur pop…

The Heineman Foundation, AIP, and AAS are pleased to announce Karen Meech, astronomer at the Institute for Astronomy, University of Hawai’i, as the winner of the 2023 Dannie Heineman Prize for Astrophysics. Meech was selected “for her pioneering work in expan…

Nutrients from salmon carcasses can substantively alter the growth and reproduction of plant species in the surrounding habitat, and even cause some flowers to grow bigger and more plentiful, SFU researchers have found.

A team from TU Wien has explained the distribution of potassium ions on the mica surface. The physical surface details of mica have never been studied on an atomic scale, and this information is important for research on electronics with 2D materials.

When birch trees are grown in highly polluted areas, their pollen contains higher levels of the main allergen, according to Polish study

Your blogger is a little tired right now… I am just back from a field trip to the salt flats in Botswana, guided by colleagues from BUIST University, walking, viewing and sampling in 38 °C heat.

Astronomers said they have recently captured a radio signal from the most distant galaxy so far.

An asteroid the size of a delivery truck will whip past Earth on Thursday night, one of the closest of such encounters ever recorded.

Chinese researchers have demonstrated laser-driven turbulent magnetic reconnection in a laboratory, an experiment that can help scientists learn more about solar flares. A paper on the findings, which reproduce key features of solar flares, has
