Quantum talk with magnetic disks

21/03/2024
Quantum computers promise to tackle some of the most challenging problems facing humanity today. While much attention has been directed towards the computation of quantum information, the transduction of information within quantum networks is equally crucial in materializing the potential of this new technology. Addressing this need, a research team is now introducing a new approach for transducing quantum information: the team has manipulated quantum bits, so called qubits, by harnessing the magnetic field of magnons -- wave-like excitations in a magnetic material -- that occur within microscopic magnetic disks.

Research suggests how turbulence can be used to generate patterns

21/03/2024
Physicists show how patterns can emerge from chaos in turbulent fluids.

Scientists find one of the most ancient stars that formed in another galaxy

21/03/2024
The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your veins and the calcium in your teeth and the sodium powering your thoughts were all born in the heart of a long-dead star.

Bacteria subtype linked to growth in up to 50% of human colorectal cancers

20/03/2024
Researchers have found that a specific subtype of a microbe commonly found in the mouth is able to travel to the gut and grow within colorectal cancer tumors. This microbe is also a culprit for driving cancer progression and leads to poorer patient outcomes after cancer treatment. The findings could help improve therapeutic approaches and early screening methods for colorectal cancer, which is the second most common cause of cancer deaths in adults in the U.S. according to the American Cancer Society.

Toba supereruption unveils new insights into early human migration

20/03/2024
Working in the Horn of Africa, researchers have uncovered evidence showing how early modern humans survived in the wake of the eruption of Toba, one of the largest supervolcanoes in history, some 74,000 years ago. Modern humans dispersed from Africa multiple times, but the event that led to global expansion occurred less than 100,000 years ago. Some researchers hypothesize that dispersals were restricted to 'green corridors' formed during humid intervals when food was abundant and human populations expanded in lockstep with their environments. But a new study suggests that humans also may have dispersed during arid intervals along 'blue highways' created by seasonal rivers. Researchers also found evidence of cooking and stone tools that represent the oldest evidence of archery.

Robotic metamaterial: An endless domino effect

20/03/2024
If it walks like a particle, and talks like a particle... it may still not be a particle. A topological soliton is a special type of wave or dislocation which behaves like a particle: it can move around but cannot spread out and disappear like you would expect from, say, a ripple on the surface of a pond. Researchers now demonstrate the atypical behavior of topological solitons in a robotic metamaterial, something which in the future may be used to control how robots move, sense their surroundings and communicate.

Quantum tornado provides gateway to understanding black holes

20/03/2024
Scientists have created a giant quantum vortex to mimic a black hole in superfluid helium that has allowed them to see in greater detail how analogue black holes behave and interact with their surroundings.

Study reveals 'cozy domesticity' of prehistoric stilt-house dwellers in England's ancient marshland

20/03/2024
Detailed reports on thousands of artifacts pulled from 'Britain's Pompeii' reveals the surprisingly sophisticated domestic lives of Bronze Age Fen folk some 3,000 years ago -- from home interiors to recipes, clothing, kitchenware and pets.

The heat index -- how hot it really feels -- is rising faster than temperature

20/03/2024
Researchers showed in 2022 that heat index calculations by NOAA based on analyses from the 1970s don't adequately reflect the heat stress humans feel during the extremes of heat and humidity accompanying climate change. Using their revised heat index, the researchers looked at Texas's summer 2023 heat wave and found that the 3 degree F rise in global temperatures has increased the state's heat index as much as 11 degrees F on the hottest days.

Astrophysicist's research could provide a hint in the search for dark matter

20/03/2024
Dark matter is one of science's greatest mysteries. Although it is believed to make up about 85 percent of the cosmos, scientists know very little about its fundamental nature. Research provides some of the most stringent constraints on the nature of dark matter yet. It also revealed a small hint of a signal that, if real, could be confirmed in the next decade or so.

Social bonding gets people on the same wavelength

20/03/2024
When small hierarchical groups bond, neural activity between leaders and followers aligns, promoting quicker and more frequent communication, according to a new study.

Low social status increases risk of health problems from alcohol problems

20/03/2024
Men and women with lower income or education levels are more likely to develop medical conditions related to alcohol abuse compared to similar individuals with a higher socioeconomic status, according to a new study.

Sea surface temperature research provides clear evidence of human-caused climate change

20/03/2024
Claims that climate change is natural are inconsistent with new oceanic temperature trends.

Craving snacks after a meal? It might be food-seeking neurons, not an overactive appetite

20/03/2024
A new study has shown that food-seeking cells exist in a part of a mouse's brain usually associated with panic -- but not with feeding. Activating a selective cluster of these cells kicked mice into 'hot pursuit' of live and non-prey food, and showed a craving for fatty foods intense enough that the mice endured foot shocks to get them, something full mice normally would not do. If true in humans, who also carry these cells, the findings could help address the circuit that can circumvent the normal hunger pressures of 'how, what and when to eat.'

Greenhouse gas emissions in Global South countries linked with IMF lending policies, study finds

20/03/2024
A study of 130 Global South nations has found that their greenhouse gas emissions were linked with IMF lending policies. The constraints of IMF's structural loans imposed coercive lending conditions that prompted borrowers to focus on increasing their exports, indirectly raising their greenhouse gas emissions through greater agricultural or manufacturing activities. GHG emissions increased within several years of countries' first structural loan, and increased almost immediately with subsequent loans, regardless of the lending conditions, the study found.

Keto diet prevents early memory decline in mice

20/03/2024
A new study shows the keto diet prevents early memory decline in mice. A molecule in the diet plays a key role in slowing Alzheimer's disease.

Monitoring and measuring biodiversity require more than just numbers; scientists advocate for change

20/03/2024
Scientists advocate for change to promote standardized practices in the field -- a practice that has been missing from the science.

ChatGPT is an effective tool for planning field work, school trips and even holidays

20/03/2024
A new study suggests anyone looking to shake off the winter blues by planning the perfect getaway should turn to ChatGPT.

Pioneering muscle monitoring in space to help astronauts stay strong in low-gravity

20/03/2024
Astronauts have been able to track their muscle health in spaceflight for the first time using a handheld device, revealing which muscles are most at risk of weakening in low gravity conditions. Researchers monitored the muscle health of twelve astronauts before, during and after a stay on the International Space Station.

Treating anxiety, depression in people with heart disease reduced ER visits, hospitalizations

20/03/2024
Treating anxiety and depression significantly reduced hospital readmission and emergency room visits in people with heart disease.This may be the first study to show that treating anxiety and depression with medication or psychotherapy has a significant impact on heart disease outcomes.
