“Every act of creation,” Picasso famously noted, “is first an act of destruction.”
Taking this concept literally, researchers in Canada have now discovered that “breaking” molecular nanomachines basic to life can create new ones that work even better.
Their findings are published today in Nature Chemistry.
During a break from looking at planets around other stars, the European Space Agency’s CHaracterising ExOPlanet Satellite (Cheops) mission has observed a dwarf planet in our own Solar System and made a decisive contribution to the discovery of a dense ring of material around it.
The dwarf planet is known as Quaoar. The presence of a ring at a distance of almost seven and a half times the radius of Quaoar, opens up a mystery for astronomers to solve: why has this material not coalesced into a small moon?
The fate of galaxies is determined by the initial mass distribution at the birth of a new population of stars in the diverse and vast Universe. This relationship is referred to as the Initial Mass Function (IMF
In the field of astronomy, initial mass function (IMF) is an empirical function that details the distribution of stellar masses in a newly formed population of stars.
Researchers at the University of Tsukuba have discovered a connection between the risk of functional disability or death in older adults and the distance they are willing to walk or cycle to reach common destinations (such as a friend’s house or a supermarket).
As they age, physical or cognitive decline can make it difficult for some older adults to navigate their community, affecting their quality of life and becoming a burden on society. However, a recent study by researchers at the University of Tsukuba demonstrates that a willingness to travel longer distances by walking or cycling may help reduce the risk of early functional disability and mortality.
A recent study published in Health and Place presents a model linking death and functional disability rates in older adults to the distances they are willing to travel on foot or bicycle for common community trips. The research found that older adults who were only comfortable with short distances – such as 500 meters or less for walking, or 1 kilometer or less for cycling – faced higher risks of functional disability and death.
Adhering to Moore’s Law, the number of transistors on a microchip has doubled annually since the 1960s, but this growth is expected to reach its limit as silicon, the foundation of modern transistors, loses its electrical properties when devices made from it dip below a certain size.
Enter 2D materials — delicate, two-dimensional sheets of perfect crystals that are as thin as a single atom.
An atom is the smallest component of an element. It is made up of protons and neutrons within the nucleus, and electrons circling the nucleus.

This video shows the humble beginnings and the 40 years of development journey of Boston dynamics’ robot ATLAS. We start with the first model developed in 1983 in the leg lab in MIT, all the way to the current version of Atlas shown in 2023 in the Boston dynamics youtube channel.
Atlas is an incredibly advanced humanoid robot that has been developed by the robotics company Boston Dynamics. It is a bipedal robot that stands at 6 feet tall and weighs 180 pounds. It is capable of performing a variety of tasks, including walking, running, jumping, and even performing backflips.

Sending a jolt of electricity through a person’s brain can do remarkable things. You only have to watch the videos of people with Parkinson’s disease who have electrodes implanted in their brains. They can go from struggling to walk to confidently striding across a room literally at the flick of a switch.
Stimulating certain parts of the brain can bring people in and out of consciousness. Even handheld devices that deliver gentle pulses to the brain can help older people remember things.
