The mech headlines that matter, in one email every morning. Free.
Quantum computers, computer systems that leverage the laws of quantum mechanics, store and process information using qubits (i.e., quantum bits). In many quantum computers, qubits are linked via entanglement, a quantum mechanical effect that connects particles in such a way that
A joint research team has identified a new mechanism underlying antibiotic resistance in Pseudomonas aeruginosa, a major multidrug-resistant "superbug." The discovery provides important clues for the development of new treatments for multidrug-resistant bacterial infections. The
Modern technological breakthroughs like lasers, MRI scanners, semiconductors and quantum computers rest on the study of quantum mechanics. However, the field has predominantly focused on (sub)atomic phenomena far removed from our human senses.
Scientists have developed a new way to make ceramic materials that can better withstand extreme heat and continue performing reliably in sensors and actuators. The approach creates tiny structures throughout the material that give it new electrical and mechanical properties.
The Intracellular Quality Control Project at the Tokyo Metropolitan Institute of Medical Science has identified a molecular mechanism that helps initiate the formation of autophagic membranes around damaged mitochondria.
If your car's engine develops a stutter, that's generally a sign that you should go to a mechanic before it stops running. We tend to think the same way about our bodies: When something's broken, something bad usually follows. There might, however, be at least one exception to th
Scandium's electrons may explain predicted room-temperature superconductivity and more — today's mech signal.
Scientists have confirmed the existence of a predicted room temperature superconductor, while explaining the microscopic mechanism that distinguishes it from a similar one discovered several years ago. The work, published in the journal Physical Review B, offers "a theoretical bl
TMEM63B, a mechanosensitive lipid scramblase, has an autoinhibitory domain in its C-terminal tail that helps keep it inactive under resting conditions, researchers from the Institute of Science Tokyo report. Changes to this regulatory region, particularly the Leu776 residue, reve
The South Asian summer monsoon has long been known to shape the Mediterranean climate thousands of kilometers away as part of a phenomenon known as the "monsoon–desert" mechanism. Through this mechanism, intense monsoon convection during the summer releases large amounts of heat
Chemicals affect biological species in different ways, posing a major challenge for assessing environmental chemical risks. However, the mechanisms behind these differences have remained largely unknown.
Every cell in an organism contains the same DNA, which carries all the instructions needed for it to function. Yet cells do not all use the same genes: A nerve cell, for example, does not activate the same genes as a muscle cell. Epigenetics refers to the mechanisms that allow ge
Africa boasts up to 25% of Earth's animal and plant species. This diversity is driven by varied habitats: harsh deserts, vast grasslands, dense forests, towering mountains, lush coastlines and teeming seas. It is also due to deep evolutionary roots, as many animal and plant group
When we think about a diamond, we often think about a material whose value comes from its perfection. In my research, however, I am interested in something almost opposite: the tiny imperfections inside diamonds. These atomic-scale defects can give diamonds new optical and electr
Meal prepping is a great way to save money, spend less time in the kitchen and stick to a meal plan. But while cooking meals for the week ahead may be convenient, there can be real risks associated with eating bulk-cooked meals.
As a teenager, Gillian Maegan Montalbo's pimples weren't too bad—just a few bumps on her forehead and nose.
Princeton Plasma Physics Laboratory may have found a dramatically more efficient route to fusion energy by reversing the traditional approach: heating plasma first, then increasing its density. Their calculations could help future reactors reach self-sustaining fusion with far le
A large study suggests loneliness and social isolation can cost people years of healthy life, especially when it comes to mental health. Men experiencing both lost about 5.8 years free from depression and anxiety, while women lost roughly 3.7 years.
Astronomers have discovered a bizarre star system about 300 light-years from Earth where a small star is slowly devouring a nearby brown dwarf, an object too massive to be a planet but too small to be a true star. Unlike stars that rapidly swallow their companions, this one is gr
Nearly 300,000 people may live in areas at risk of flooding in the Nepalese, Indian and Chinese areas of the Himalayas. The results, from a study published in Scientific Reports, also indicate that the total area covered by buildings within potential flood zones increased by appr
Most of us recognize basic phases of matter and their properties: solids maintain their shape, liquids flow freely with constant volume, and gases expand to fill their container. Quantum phases, on the other hand, are much harder to categorize, overturning traditional notions of
Two cartoon characters appear on a screen. One belongs to a group of three, and the other to a group of two. Which character would you rather play with?
From coral reefs in Papua New Guinea to chimpanzees in West Africa, grizzly bears in Canada and albatross colonies off Tasmania, some ecosystems are thriving despite climate change, habitat loss and other environmental pressures.
Powerful waves thrashed communities along California's southern coast Friday, damaging homes and sending water cascading through streets as residents braced for more potential damage wrought by Tropical Storm Rachel.
