Tokyo, Japan – The exponential miniaturization of electronic chips over time, described by Moore's law, has played a key role in our digital age. However, the operating power of small electronic devices is significantly limited by the lack of advanced cooling technologies available.  Aiming to tackle this problem, a study published in Cell Reports Physical Science, led by researchers from the Institute of Industrial Science, The University of Tokyo, describes a significant increase in performance for the cooling of ...

Researchers led by Jean-Paul Noel at the University of Minnesota, United States, have decoupled intentions, actions and their effects by manipulating the brain-machine interface that allows a person with otherwise paralyzed arms and legs to squeeze a ball when they want to. Published in the open-access journal PLOS Biology on April 17th, the study reveals temporal binding between intentions and actions, which makes actions seem to happen faster when they are intentional. Separating intentions from actions was made possible because of a brain-machine interface. The participant was paralyzed with damage ...

A new Bluetooth-based positioning system could offer healthcare systems a low-energy, low-cost method of tracking older adults’ mobility, according to a new study published this week in the open-access journal PLOS Digital Health by Qiyin Fang of McMaster University, Canada, and colleagues. Global Positioning System (GPS) is the dominant positioning technology today, but its use indoors is limited due to the difficulty in communicating with GPS satellites. However, the knowledge of a person’s position is critical for many real-time healthcare applications, ...

Americans are more likely to discuss climate change with family and friends if they feel worried or at risk, perceive society as supportive of pro-climate behaviors or see global warming depicted in the media, according to a study published April 17, 2025 in the open-access journal PLOS Climate by Margaret Orr from George Mason University College of Humanities and Social Sciences in Fairfax, Virginia, and colleagues. Curbing global warming’s effects requires systemic changes and government policies to reduce carbon emissions. Among individual climate actions (e.g., ...

How do we learn something new? How do tasks at a new job, lyrics to the latest hit song or directions to a friend’s house become encoded in our brains? The broad answer is that our brains undergo adaptations to accommodate new information. In order to follow a new behavior or retain newly introduced information, the brain’s circuity undergoes change. Such modifications are orchestrated across trillions of synapses — the connections between individual nerve cells, called neurons — where brain communication takes place. In an intricately coordinated ...

UNDER EMBARGO UNTIL 19:00 BST / 14:00 ET THURSDAY 17 APRIL 2025 Sugar-mimicking molecule central to virulence of a common crop disease, study finds In plants, the space between cells is a key battleground during infection. To avoid recognition in this space, a strain of the bacterial tomato disease Pseudomonas syringae manipulates plants by producing a substance called glycosyrin. This substance suppresses the immune response and allows the bacteria to remain unnoticed. A new study led by the University of Oxford has revealed ...

Shedding light on how the brain fine-tunes its wiring during learning, a new study finds that different dendritic segments of a single neuron follow distinct rules. The findings challenge the idea that neurons follow a single learning strategy and offer a new perspective on how the brain learns and adapts behavior. The brain's remarkable ability to learn and adapt is rooted in its capacity to modify the connections within its neural circuits – a phenomenon known as synaptic plasticity, in which specific synapses are altered to reshape neural activity and support behavioral change. Neurons, unlike most other cell types, are characterized by their intricate, ...

Solid-state lithium batteries fail for the same reason over-bent paperclips snap – metal fatigue in the anode itself, according to a new study. The findings, which show that this fatigue follows well-documented mechanical behavior, provide a quantitative framework for predicting the cycle life of solid-state batteries, enabling new pathways for designing longer-lasting and safer energy storage systems. Solid-state lithium metal batteries (SSBs) promise both high energy and improved safety by combining a lithium ...

NASA’s Curiosity rover has uncovered a hidden chemical archive of ancient Mars’ atmosphere, which suggests that large amounts of carbon dioxide have been locked into the planet’s crust, according to a new study. The findings provide in situ evidence that a carbon cycle once operated on ancient Mars and offer new insights into the planet’s past climate. The Martian landscape shows clear signs that liquid water once flowed across its surface, which would have required ...

Based on data from over 1000 regional studies combined with machine learning, researchers estimate that as many as 1.4 billion people live in areas with soil dangerously polluted by heavy metals like arsenic, cadmium, cobalt, chromium, copper, nickel, and lead. The study reveals a global risk, but also a previously unrecognized high-risk, metal-enriched zone in low-latitude Eurasia, in particular. The growth in demand for critical metals means toxic heavy metal pollution in soils is only likely to worsen. “We hope that the global soil pollution data presented in this report will ...

Research from NASA’s Curiosity rover has found evidence of a carbon cycle on ancient Mars, bringing scientists closer to an answer on whether the Red Planet was ever capable of supporting life. Lead author Dr. Ben Tutolo, PhD, an associate professor with the Department of Earth, Energy and Environment in the Faculty of Science at the University of Calgary, is a participating scientist on the NASA Mars Science Laboratory Curiosity Rover team.

About The Study: The results of this cohort study suggest that treating hearing loss might delay dementia for a large number of older adults. Public health interventions targeting clinically significant audiometric hearing loss might have broad benefits for dementia prevention. Future research quantifying population attributable fractions should carefully consider which measures are used to define hearing loss, as self-reporting may underestimate hearing-associated dementia risk.

CAMBRIDGE, MA -- Cleft lip and cleft palate are among the most common birth defects, occurring in about one in 1,050 births in the United States. These defects, which appear when the tissues that form the lip or the roof of the mouth do not join completely, are believed to be caused by a mix of genetic and environmental factors. In a new study, MIT biologists have discovered how a genetic variant often found in people with these facial malformations leads to the development of cleft lip and cleft palate. Their findings suggest that the variant diminishes cells’ supply of transfer RNA, a molecule ...

A new discovery could pave the way for more effective cancer treatment by helping certain drugs work better inside the body. Scientists at Duke University School of Medicine, University of Texas Health Science Center at San Antonio, and University of Arkansas have found a way to improve the uptake of a promising class of cancer-fighting drugs called PROTACs, which have struggled to enter cells due to their large size. The new method works by taking advantage of a protein called CD36 that helps pull substances into cells. By designing drugs to use this CD36 pathway, researchers delivered 7.7 to 22.3 times more of the drug inside cancer cells, making ...

BUFFALO, N.Y. — A vaccine under development at the University at Buffalo has demonstrated complete protection in mice against a deadly variant of the virus that causes bird flu.

A research team has decoded the genome of historic potato cultivars and used this resource to develop an efficient method for analysis of hundreds of additional potato genomes. Potatoes are a staple food for over 1.3 billion people. But despite their importance for global food security, breeding successes have been modest. Some of the most popular potato cultivars were bred many decades ago. The reason for this limited success is the complex genome of the potato: there are four copies of the genome in each cell instead of just two. ...

Research Highlights: Among adults ages 18-49 (median age of 41 years) who were born with a hole in the upper chambers of their heart known as patent foramen ovale (PFO), strokes of unknown cause were more strongly associated with nontraditional risk factors, such as migraines, liver disease or cancer, rather than more typical factors such as high blood pressure. Migraine with aura was the top factor linked to strokes of unknown causes, also called cryptogenic strokes, especially among women. Embargoed ...

Three consecutive years of drought contributed to the ‘Barbarian Conspiracy’, a pivotal moment in the history of Roman Britain, a new Cambridge-led study reveals. Researchers argue that Picts, Scotti and Saxons took advantage of famine and societal breakdown caused by an extreme period of drought to inflict crushing blows on weakened Roman defences in 367 CE. While Rome eventually restored order, some historians argue that the province never fully recovered.   The ‘Barbarian Conspiracy’ of 367 CE was one of the most severe threats to Rome’s hold on Britain since the Boudiccan revolt three centuries earlier. Contemporary sources indicate that components ...

If you have ever chickened out of eating chicken, your unease may not have been unreasonable. Osaka Metropolitan University researchers have detected alarming rates of Escherichia albertii, an emerging foodborne pathogen, in retail chicken meat in Bangladesh. Their findings show extensive contamination and significant antimicrobial resistance, underscoring the potential risks to public health. E. albertii is a less known but probably not less dangerous relative of E. coli. First described in Bangladesh in 2003, this bacterium ...
