In most modern cells, DNA stores the genetic blueprint, and proteins replicate, repair and build from those blueprints. At the same time, proteins require instructions from DNA to be made in the first place.
Recent improvements in our understanding of how the principles of thermodynamics apply in the quantum realm could give a boost to quantum technology, and a clearer picture of quantum thermodynamics could in turn enhance our understanding of classical thermodynamics. Now, Aalto
A record-breaking heat wave baked the central United States on Sunday, smashing temperature records from the northern Plains to the Rocky Mountain region.
At least 2,700 people died in England and Wales as a result of heat waves that struck in May and June, according to a study released Monday.
For half a century, millions of workers have repeated a task across the deserts in northern China: inserting forearm-length sticks into shifting sand, first in a row, then in an intersecting line, gradually forming a grid. Then saplings are planted at the center of each small
Researchers found that bacteria linked to gum disease may help drive the development of calcific aortic valve stenosis by triggering inflammation and calcium buildup in the heart valve. The early findings suggest that keeping gums healthy could play a role in reducing the risk
A new study suggests spacecraft exhaust could quickly contaminate the moon's most scientifically valuable regions, potentially masking ancient clues about how life began on Earth. Researchers say future lunar missions should consider new ways to reduce and monitor this
Citizen scientists have helped researchers solve a long-standing mystery about how parental care evolved in harvestmen. Using photos and observations from iNaturalist, scientists more than doubled the known cases of egg-guarding behavior and discovered that maternal and
It can be easy to get sucked into social media for hours on end. Funny, cartoony science videos may be especially interesting, but not to everyone, according to a recent study from the University of Georgia.
Efforts to plant more trees in cities could be boosted thanks to a new tool for planners and community groups, published by an international group of researchers. Residents, policymakers and tree officers in Cardiff, Milton Keynes, Edinburgh, York and Camden worked with
Portable screen-printed carbon electrode (SPCE) biosensors offer a rapid, low-cost way to detect microcystin-lysine-arginine (MC-LR), an extremely potent toxin produced by cyanobacteria during harmful algal blooms in freshwater. Even at low concentrations, MC-LR can damage the
For years, we've been told a familiar story: Social scientists such as economists, management scholars and sociologists talk, and the public shrugs. The claim goes that people don't find our work interesting, that our expertise is fuzzy compared with "hard" sciences, and that
Materials with magnetic nanostructures have a wide range of potential applications. One area is so-called spintronics, with devices that encode information in magnetic domains. These magnetic bits can be written, read and erased in a more energy-efficient way than bits in
Microsoft PowerPoint has become the default tool for presenting learning materials in classrooms, universities, corporate training programs, webinars and remote learning environments. But is it being used effectively? This question arises because learners face a major
Light Emitting Diodes (LEDs) are used in everything from household lighting and mobile phones to large display screens. Improving their efficiency could reduce energy use and enhance performance across a wide range of technologies. A new study involving researchers from the
In drug discovery, building complex molecules quickly is the name of the game.
Tree swallows in the northern U.S. and Canada face the greatest risk from climate change despite responding to temperature the same way as tree swallows in the southern U.S., according to a new study led by Cornell researchers that analyzed nearly 95,000 nests across five
Domestic and family violence is an epidemic. In 2024, the prime minister declared it a national crisis. Official statistics show time and again that this violence is overwhelmingly perpetrated by men. This is unlikely to be news to most of us—we see it play out in our
To better assess the danger posed by volcanoes, researchers at the Technical University of Munich (TUM) have developed a new measurement system. Laser beams are sent through escaping gas clouds and reflected by drones. An algorithm uses the reflected signals to generate a map
I am one of Hobart's many residents who traveled to a nearby beach to witness Neil the seal—an animal that has been receiving global attention for his wild personality and humorous antics.
Long before scientists began studying them in the lab, mind-altering substances were already being gathered from plants, fungi and even animals for use in rituals, healing practices and mental health treatment. Researchers at the Weizmann Institute of Science have now managed
Rotaxanes are dumbbell-shaped mechanically interlocked molecules in which one or more ring-shaped molecules are threaded through a linear segment, known as the axle. To keep the ring from sliding off, two bulky groups, sometimes called stoppers, are added to the ends of the
Hillslopes in Arctic regions with frozen soils can host a suite of geometric patterns, from circles and stripes to polygonal patterned ground. They can also have solifluction patterns, or markings left behind when partially thawed permafrost slips and flows down a slope.
Far beneath the surface of the ocean lies the largest and least explored habitat on Earth. The deep sea is cold, dark, highly pressurized—and home to a huge amount of undiscovered life.
For researchers on the hunt for the genetic roots of disease, the cost of deep whole-genome sequencing makes it challenging to conduct large genetic studies involving thousands of participants, which are needed to reveal new genetic insights. So scientists at the Broad
Since gravitational waves were first detected in 2015, instruments including LIGO, Virgo and KAGRA have picked up a steady stream of signals from colliding black holes, building a catalog that now numbers in the hundreds. Yet despite this wealth of data, a fundamental question
Nature is beautiful, powerful and essential. But nature is not always gentle. The same biological world that gives rise to forests, coral reefs and human life also produces infections, cancer, genetic disease, crop blights and toxins. Natural processes can heal, sustain and
Why do some coral reefs weather marine heat waves better than others? A new study published in Scientific Reports shows that the answer may lie not only in local ocean conditions, but also in climate patterns that span entire ocean basins. By combining long-term ocean
Researchers found that tau is essential for turning new experiences into lasting memories by helping organize the brain's memory-storing cells. The mouse study also revealed how abnormal tau may contribute to Alzheimer's by disrupting both the formation of new memories and the
The Euclid space telescope has spotted the oldest quasars—the brightest objects in the universe—ever discovered, deepening a cosmic mystery that has been puzzling scientists.
Researchers have recreated the physics of extracting energy from a spinning black hole using a stationary device that produces synthetic ultrafast rotation. The achievement transforms a long-standing theoretical idea into a practical experiment and could inspire new advances in
Scientists discovered that extreme deep-sea pressure squeezes valuable nutrients out of sinking organic particles, providing an unexpected food source for ocean microbes. The finding could rewrite our understanding of both deep-ocean ecosystems and how carbon is stored on Earth.
Nanocrystals are already used in millions of devices, including televisions, laptops and displays, and are considered key materials for the next generation of quantum, sensing and solar technologies. However, they have not yet fully realized their potential. One major reason is
Alpha-gal syndrome is increasing across the U.S., driven by lone star ticks
A simple, non-invasive ultrasound treatment could one day help injured joints heal instead of remaining trapped in a cycle of damaging inflammation. Researchers at The University of Alabama in Huntsville found that continuous low-intensity ultrasound encouraged key immune cells
The sheer amount of insects that free-range cats consume might surprise you
