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 semiconductor devices approach the atomic scale.
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 and 10% of global energy consumption. Increasing the use of recycled metals could significantly reduce the environmental impact of metal production while also lowering dependence on imports of scarce and strategically critical raw materials.
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.
While working on his land in a village in northern Egypt, a man made an astonishing discovery: the remains of two massive statues of Ramesses II.The man, Khaled el-Shahat, immediately notified the Egyptian Ministry of Tourism and Antiquities, which sent a team to the village of Behbeit El Hagar to excavate and study the statues, the ministry said in a translated statement.Ramesses II had one of the longest reigns in Egypt's history, ruling from around 1279 to 1213 B.C. During his 66 years in power, Egypt controlled an empire that stretched as far northeast as modern-day Syria. He initiated many building projects throughout the empire, and numerous Ramesses II statues have been found througho...
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 global carbon cycle. But satellites have a fundamental limitation: they can only see the ocean's surface.
Employers must do more to remove the barriers preventing women with disability from progressing into leadership, according to a new report from People with Disability Australia (PWDA), the national disability rights and advocacy organization. Researchers identify six lessons to help drive change.
Computer models suggest that unrealistically cold oceans would be insufficient to stop Thwaites glacier retreating, although a neighbouring glacier might begin to grow
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 repurposed to create elaborate social displays: Birds of paradise fan out their wings and hop around in courtship dances, while crabs wave their claws to communicate to potential mating partners. As humans, we use our limbs to dance, gesture while talking, wield tools and conduct a remarkable diversity of behaviors. How does the brain control and coordinate its body parts for such distinct purposes?
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 perimeter of their fields or lawns stronger, the researchers say. The study results are published in the journal New Phytologist.
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 straight away, but it will be game over if the stress continues long enough for them to starve.
