A gene called GATA6 (GATA binding protein 6) regulates aging of human mesenchymal stem/stromal cells (MSCs), according to new research from the University of Wisconsin-Madison. Cellular reprogramming can reverse the aging that leads to a decline in the activities and functions of MSC cells. This is something that researchers have known for a while. But [...]

Researchers have recently measured the propagation speed of ultrasonic waves in an aluminum-rich hydrous mineral called Al-phase D at pressure conditions relevant to the Earth's deep mantle. Their results suggest that seismic shear anomalies observed locally beneath subduction zones may reveal the presence of hydrous minerals in the uppermost lower mantle, which would have important implications for the Earth's interior because hydrogen affects considerably the physical and chemical properties of mantle minerals.

One of world's earliest examples of art, the enigmatic `Venus' figurines carved some 30,000 years ago, have intrigued and puzzled scientists for nearly two centuries. Now a researcher believes he's gathered enough evidence to solve the mystery behind these curious totems.

The drama introduces Britain's controversial first woman prime minister, played by Gillian Anderson.

This June, the Global program of the University of São Paulo (USP) carried out the research (lit. Momentary Emotions) to measure how the pandemic was changing the relationship of individuals with public spaces in São Paulo. Among the collected data, there was one that caught the attention of the group of researchers: 86% of the surveyed people wanted to spend time in such as parks and squares.

Researchers have made reported some exciting findings relating to metal-organic frameworks (MOFs), a class of porous materials, which could benefit a wide range of important gas separation processes.

Researchers have studied the mechanisms by which the novel coronavirus can reach the brains of patients with COVID-19. The results show that SARS-CoV-2 enters the brain via nerve cells in the olfactory mucosa.

A mass screening program of 10 million Wuhan residents identified 300 asymptomatic cases in May, but none were infectious, according to a new study. Researchers found no 'viable' virus in the asymptomatic cases and the close contacts of these positive asymptomatic cases did not test positive. But these findings do not show that the virus can't be passed on by asymptomatic carriers. Rather, mask-wearing, hand washing, social distancing and lockdown have helped reduce Covid-19 virulence.

Researchers have discovered a molecular mechanism that plays a central role in intact long-term memory. This mechanism is also involved in physiological memory loss in old age.

Induced pluripotent stem cells (iPS) have the potential to convert into a wide variety of cell types and tissues. However, the 'recipes' for this conversion are often complicated and difficult to implement. Researchers have now found a way to systematically extract hundreds of different cells quickly and easily from iPS using transcription factors.
