Earth can regulate its own temperature over millennia

The global carbon cycle exerts substantial control over Earth’s climate. Still, life on Earth has kept on beating for the last 3.7 billion years. Understanding Earth’s history, the long-term effects of anthropogenic climate change, and planetary habitability depend on how the climate is maintained on geologic time scales. MIT scientists have confirmed that the Earth has

Brain-powered wheelchair shows real-world promise

Daily usage of brain-controlled robots and neuroprostheses is the paramount promise of brain-machine interface (BMI) for people suffering from severe motor disabilities. A new study by the University of Texas at Austin takes a step forward for brain-machine interfaces — computer systems that turn mind activity into action. In this study, several people with motor

Ancient disease have the surprising ability to regenerate livers

Leprosy, also known as Hansen’s disease (HD), is one of the world’s oldest and most persistent diseases caused by Mycobacterium leprae. A new study by the University of Edinburgh showed the previously unexplored ability of the bacteria causing Leprosy. Scientists have shown that the bacteria that cause it may also have the surprising ability to

How do 2D materials expand when heated?

Two-dimensional (2D) materials, consisting of a single layer of atoms, are generally used in modern miniaturized devices. However, device operation may lead to substantial temperature rise and thermal stress, causing device failure. Such a problem occurs due to a poor understanding of how 2D materials expand when temperatures rise. These materials are thin and optically

Patterns of mass extinction coincided with rapid decrease in marine oxygen levels

The Late Ordovician mass extinction (LOME) is the first of the “big five” major mass extinction events in Earth’s history. It occured almost 443 million years ago, eliminating about 85% of marine species. It is often considered the second-largest known extinction event in terms of the percentage of extinct genera. Long-term research into this mass

Webb revealed once-hidden features of the protostar

The NASA/ESA/CSA James Webb Space Telescope has revealed the once-hidden features of the protostar within the dark cloud L1527 with its Near Infrared Camera (NIRCam), providing insight into the formation of a new star. These blazing clouds within the Taurus star-forming region are only visible in infrared light, making it an ideal target for Webb.

New device to non-invasively measure cervical nerve activity in humans

Sepsis is a life-threatening response to infection, and mental health conditions, such as post-traumatic stress disorder (PTSD). A team of engineers and physicians at the University of California San Diego has developed a flexible, adhesive-integrated device to measure cervical nerve activity in humans non-invasively. This tool could potentially be used to inform and improve treatments

Mars churns up surprisingly Earth-like cloud patterns

The Springtime season in Mars’ northern hemisphere is characterized by rich atmospheric dynamical activity. This activity occurs at the polar cap’s edge, often revealed by the presence of local dust storms. A new study dives deeper into two martian dust storms that occurred near the martian North Pole in 2019. The cloud patterns are surprisingly

New nanoscale 3D printing material could offer a better structural protection

Designing various 3D structures for mechanical performance is currently of great interest. But in reality, 3D printing is still limited in the properties and materials available for use, especially when printing at very small scales. Scientists at Stanford have developed a new material for printing at the nanoscale. They also used the newly created material

A new map of the universe displays the entire known cosmos

Johns Hopkins University astronomers have created a new map of the universe. This is the first time the span of the known cosmos has been shown with pinpoint accuracy and sweeping beauty. To create the map, astronomers mined over two decades through the Sloan Digital Sky Survey. The Sloan Digital Sky Survey (SDSS) is a

A new method to ‘see’ the fine structure and chemical composition of a human cell

While nanoscale structural imaging of cells is now possible, a direct recording of the chemical composition of these domains is lacking. A novel technique was created by scientists at the Beckman Institute for Advanced Science and Technology to “see” the intricate details and chemical composition of a human cell with unparalleled clarity and precision. Their

Introducing Unimon: A new superconducting qubit for quantum computers

Superconducting qubits seem promising for useful quantum computers, but the currently widespread qubit designs and techniques do not yet provide high enough performance. A group of scientists from Aalto University, IQM Quantum Computers, and VTT Technical Research Centre have introduced a new superconducting qubit called Unimon. This Unimon is claimed to increase the accuracy of
