Retail research shifted in five ways, study finds

1 day 12 hours ago
Retail research has changed during the last couple of decades, according to an analysis of almost 5,200 papers covering business practices, consumer behavior and technology. The study, published in the International Journal of Electronic Marketing and Retailing, considered papers from the four leading specialist journals in this area.

Silicon qubits surpass 99.99% gate fidelity while operating three at once

1 day 12 hours ago
Silicon spin qubits are a promising platform for building scalable quantum computers as they are compatible with the semiconductor manufacturing technologies used to produce today's computer chips. However, they have an important weakness: silicon spin qubits typically lose accuracy when several qubits are under parallel control. To be useful, quantum computers will need to operate many qubits simultaneously without compromising the accuracy of their operations.

AI turns scrap impurities into useful ingredients for stronger recycled iron

1 day 13 hours ago
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.

North Sea heat wave fueled underwater plankton bloom largely missed by satellites

1 day 13 hours ago
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.

Two brain circuits coordinate fruit flies' wing and leg movements to threaten rivals

1 day 14 hours ago
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?

Researchers find that some weeds get supercharged by an indirect hit of herbicide

1 day 14 hours ago
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.

Better together? Coral fusion could throw bleached reefs a lifeline

1 day 14 hours ago
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.

Lion tracks from the ice age: How two ways of seeing brought ancient animals to life

1 day 14 hours ago
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 extensive habitat for large mammals. At other times the sea level was briefly as much as 13 meters (43 feet) higher than today's mean level.

New DNA sequencing methods detect rare mutations acquired as bodies grow and age

1 day 14 hours ago
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 of Health Common Fund initiative to catalog all the normal processes of somatic mutation, has published its first comprehensive benchmarking study in the journal Cell.

How COVID reshaped college grading

1 day 15 hours ago
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.
