The preferred “handedness” of biomolecules could have emerged from interactions between electrons and magnetic surfaces on primordial Earth, new research suggests.

Tesla Cybertruck Spotted Next To Rivian R1T Showing Size Difference
One of the biggest unknowns regarding the upcoming Tesla Cybertruck was and still is its size, but a set of new photos posted online on the Cybertruck Owners Club forum shed some light on the matter.
In the images (embedded below), a release candidate (RC) Cybertruck is stopped at a Tesla Supercharger, and a Rivian R1T is parked right next to it, giving us an idea of what to expect when the angular all-electric pickup hits the market toward the end of this year (probably).
Judging from the photos, the Cybertruck seems a bit wider and longer than the R1T. For reference, Rivian’s pickup measures 217.1 inches long, 81.8 in wide (with the side mirrors folded), and 78.2 in tall (with the antenna accounted for and the suspension in its highest setting).
Fall Prevention: Balance and Strength Exercises for Older Adults
While it’s not possible to completely prevent a fall, exercises that focus on balance and strength training can reduce the risk of falling. “We treat elderly adults for injuries sustained from falls, and other patients who feel unsteady while walking or standing and are fearful of falling,” says Lora Stutzman, a physical therapist with the Johns Hopkins Rehabilitation Network. “These exercises can help improve balance and build strength to help prevent future falls.”
For older adults, activities such as squatting, standing up from a chair and walking may be difficult or cause them to feel unsteady, which increases their risk of falling. The following exercises are intended for those who have a low risk of fall and are able to stand on their own without support from others. Always talk to your doctor or physical therapist first before starting new exercises, especially if you have weak balance.
Stutzman demonstrates two exercises below.

Zaha Hadid Architects wins major China cultural district competition with large ‘feather’ roofs
Zaha Hadid Architects has won a competition for the design of a new harborfront district in the Chinese city of Sanya. Located on the southern tip of Hainan island, the area attracts 80 million tourists each year for its forests and beaches, a demand that is driving the development of the new harbor district.
NASA’s SPICES sensor to assess the origins of matter in space
It will detect plasma in space and track it back to the Sun, planetary atmospheres, comet tails, and interstellar space.
NASA is working on a concept similar to a hidden decoder ring with which you can read a secret message containing significant information about the objects around you: where they originated from, why they are there, and what will happen to them in the future.
Now, consider the secret decoder ring, a sensor that can be launched into space to reveal secrets about matter in the solar system. Where did this matter come from, how did it get electrified, and how can it affect humanity on Earth and in space?
How Rotation Drives Magnetic Levitation
A detailed experimental analysis explains the forces by which a spinning magnet can cause another magnet to levitate in midair.
Magnetic levitation is common in floating trains and high-speed machinery, but two years ago, a new type of levitation was discovered that uses a rapidly rotating magnet to suspend a second magnet in the air. Researchers have now clarified that this phenomenon originates from slight tilts in the magnetic axes of the magnets relative to their rotational axes [1]. The research team’s experimental and theoretical work reveals surprises about how magnetic levitation works. The new technique could one day be used as a contact-free tool for manipulating objects.
If you bring together two toy magnets with their north poles facing each other, they will repel each other. You might be tempted to try and use that repulsion to counter the force of gravity by placing one magnet beneath the other. However, common experience shows that this balancing act is unstable.
