A transistor normally requires several fundamentally different materials—a semiconductor to carry current, an insulating dielectric to control it and metallic contacts through which current enters and leaves. Integrating all of these components becomes increasingly difficult as
More than 30 years after the direct connection was established between the molecular machinery controlling cell division and cancer, a new paper traces the evolution of cyclin-dependent kinase research and outlines the next generation of CDK-targeted therapies.
About 2 billion metric tons of metal are produced worldwide every year to meet the demands of industry, infrastructure and the energy sector. Much of this production still relies on primary raw materials, contributing to an estimated 40% of industrial greenhouse gas emissions
On Oct. 17, 1346, the Battle of Neville's Cross was fought outside Durham in the northeast of England. It was a decisive moment in Anglo-Scottish history that led to the capture of King David II of Scotland. Yet few have heard of it.
When a marine heat wave strikes, scientists often turn to satellites to see how the ocean is responding. From space, changes in ocean color can reveal shifts in phytoplankton, microscopic organisms that form the foundation of marine food webs and play a crucial role in the

Limbs evolved as a means of locomotion. From the primitive rotating flagella of bacteria to the wings of flies and even our own legs, animals use these appendages to travel to find food or mates or escape predators. But in countless species across the animal kingdom, limbs are
The Earth got its moon when a small planet collided with our planet more than 4 billion years ago. This impact hurled molten rock into space, which eventually coalesced to form the satellite we can see every night from across our planet.
A brush with low doses of the herbicide dicamba spurs oxalis, a weed commonly known as wood sorrel, to produce more flowers, University of Michigan researchers have discovered. The finding suggests that farmers and homeowners are inadvertently making weeds growing around the
When corals are stressed by pollution, high water temperatures or other environmental changes, they can lose the microscopic algae living inside them and on which they depend for food. As a result, they turn white, a phenomenon known as coral bleaching. They will not die
The coastline near the southern tip of Africa looked vastly different between about 400,000 years ago and 70,000 years ago, compared with today. At times it lay as much as 100km (62 miles) south of its present location, exposing the vast Palaeo-Agulhas Plain, which contained an
Somatic mutations, the DNA changes that occur as our bodies grow and age, not only hold an important key to cancer but are emerging as the seeds of a wide range of common, noncancerous diseases. The Somatic Mosaicism across Human Tissues (SMaHT) Network, a National Institutes

Twenty-three Indiana University undergraduates are co-authors on a new study examining how the pandemic reshaped college grading, the result of a semester-long research seminar that took them from a classroom question to a published paper in a national academic journal.
The University of Bristol–led study, published in Nature Communications, could help millions of people living in earthquake-prone countries make better-informed decisions about seismic risk, particularly during ongoing periods of increased earthquake activity.
A super El Niño fueling record ocean temperatures poses a "terrifying" threat to the world's fragile coral reefs, the chair of the U.N.'s expert nature panel told AFP.
Chitin, a chain of repeating sugar molecules, is the main building block of fungal cell walls. When fungi grow or are broken down, fragments of chitin chains of different lengths end up in the soil, and plants detect them to monitor the microbes around them.
Earlier this fall, researchers Sara Kalucza (Department of Sociology) and Anna Baranowska-Rataj (Center for Demographic and Aging Research, CEDAR) at Umeå University published a research article showing a connection between young people's school-to-work transitions and parental
Salty soil is a growing threat to crops worldwide. Hotter, drier weather has increased evaporation rates, drawing moisture from the soil and leaving behind concentrated mineral salts. At the same time, water shortages are forcing farmers to irrigate using water from
A new study led by the Woods Hole Oceanographic Institution (WHOI) provides the most comprehensive observational analysis yet of the towering ice cliffs that fringe Earth's ice sheets, giving scientists new evidence to evaluate a long-debated process that could influence future
My recent discovery of a Roman fort and its extraordinary connection with medieval folklore was the fruition of many hours of painstaking research.
An international study has overturned a longstanding textbook view of how much energy animals use to travel, revealing that flying can sometimes be cheaper than swimming.

In an effort to conserve the world's plants and animals, governments have pledged to conserve 30% of the planet by 2030. Official figures suggest that attempts to reach this target on land have stalled, but a new study led by the Durrell Institute of Conservation and Ecology at
Americans who trust science and reason more than their churches' teachings, but still believe in God or attend services, are also more likely to believe in magic than those who prioritize religious teachings.
The spectacled cobra (Naja naja) is one of India's "big four" snakes responsible for most serious snakebite cases. It is currently considered one species, which lives across much of South Asia, with regional differences in color, hood markings and venom. However, it's still
Nearly 50 million Americans ages 18 to 29 are eligible to vote in the upcoming midterm elections, and about 60% say they plan to. If they follow through, it would break midterm turnout records for voters under 30.
Three answers, three countries, one open-ended question: "Teaching is similar to what other occupation or activity?"
Physicists at Auburn University have used flashes of laser light to bring order to tiny electrically charged "islands" inside a crystal. The discovery helps answer a decades-old question about how the material organizes itself and shows how light could be used to control its
