The quantum systems employed in quantum technologies, for example single atoms, are also very sensitive: any interaction with the environment can induce changes in the quantum system, leading to errors. However, this remarkable sensitivity of quantum systems to environmental factors actually represents a unique advantage. This sensitivity enables quantum sensors to surpass conventional sensors in precision, for example when measuring magnetic or gravitational fields. Noise cancellation using correlation spectroscopy The delicate quantum properties needed for sensing can be covered up ...

SAN DIEGO – Funding of field conservation research stations worldwide has been drastically reduced since the beginning of the COVID-19 pandemic, raising the alarm of more than 170 conservation researchers representing 157 field stations in 56 countries in a new paper published in Conservation Letters. The authors contend that field research stations have a high return on investment and are essential and highly effective tools for biodiversity conservation. Trillions of U.S. dollars were mobilized in economic recovery following the pandemic, yet the authors raise concerns ...

There is a pressing need to explore and understand which social determinants of health (SDOH) and health inequities act as significant influential factors that contribute to low breast cancer screening behaviors in the United States. Health disparities have been consistently associated with delayed screening, which then contributes to higher mortality rates among both Hispanic and Black populations. Moreover, poverty, lack of education, neighborhood disadvantage, residential segregation, racial discrimination, lack of social support and social isolation ...

Aortic aneurysms are bulges in the aorta, the largest blood vessel that carries oxygen-rich blood from the heart to the rest of the body. Smoking, high blood pressure, diabetes, or injury can all increase the risk of aneurysms, which tend to occur more often in Caucasian male smokers over the age of 65.  “The soft tissues that make up blood vessels act essentially like rubber bands, and it’s the elastic fibers within these tissues that allow them to stretch and snap back,” says Professor Anand Ramamurthi, chair of the Department of Bioengineering in Lehigh University’s P.C. Rossin College of Engineering ...

New research definitively shows that HIV antiretrovirals can be taken together with gender-affirming hormone therapy without changing how well either drug works. The study findings can help healthcare providers address potential patient concerns that one drug will counteract the other. “This study is the first head-to-head pharmacokinetic analysis of two common HIV medications and long-term feminizing hormone therapy use,” says Walter Kraft, MD, director of the Division of Clinical ...

Cervical cancer is among the most common malignancies affecting women worldwide. In 2020 alone, approximately 600,000 women were diagnosed with this disease, and over 314,000 died from it. In 99% of the cases, cervical cancer cells harbor human papilloma virus (HPV), and thus, HPV vaccines are an effective way to mitigate the risk of developing this disease. Unfortunately, such preventive measures are useless against established cancers, which are generally incurable once they become metastatic or relapsing.   Fortunately, scientists have made substantial progress in developing a promising ...

A new analysis of freshwater resources across the globe shows that human activity has pushed variation in the planet’s freshwater cycle well outside of its pre-industrial range. The study shows that the updated planetary boundary for freshwater change was surpassed by the mid-twentieth century. In other words, for the past century, humans have been pushing the Earth’s freshwater system far beyond the stable conditions that prevailed before industrialization. This is the first time that global water cycle change has been assessed over such a long timescale with an appropriate reference baseline. The findings, published in Nature Water, show that human ...

CAMBRIDGE, MA -- When listening to music, the human brain appears to be biased toward hearing and producing rhythms composed of simple integer ratios — for example, a series of four beats separated by equal time intervals (forming a 1:1:1 ratio). However, the favored ratios can vary greatly between different societies, according to a large-scale study led by researchers at MIT and the Max Planck Institute for Empirical Aesthetics and carried out in 15 countries. The study included 39 groups of participants, many of whom came from societies ...

WINSTON-SALEM, N.C. – March 4, 2024 – Parkinson’s disease is a neurological disorder that affects movement and muscle control. One characteristic of the disease is the deficiency of dopamine, a neurotransmitter or brain chemical that plays a role in movement and can impact how people think and feel. Dopaminergic medicines can help alleviate the symptoms of Parkinson’s disease. However, in some patients, the medications can cause impulse control disorder (ICD), characterized by risky behavior such as excessive gambling, shopping, ...

There are stark differences between European countries when it comes to both the reimbursement of, and access to, new treatments for patients with early-stage lung cancer. There are also differences in reimbursement times and indications between the European Medicines Agency (EMA) and the US Food and Drug Administration (FDA). Researchers from Amsterdam UMC Cancer Center Amsterdam analysed the landscape, and their results are published today in The Lancet Regional Health Europe as part of a series on the latest developments in the treatment of this lung cancer.   "Tackling inequalities in access to care must be a common European priority," ...

Problems with iron levels in the blood and the body’s ability to regulate this important nutrient as a result of SARS-CoV-2 infection could be a key trigger for long COVID, new research has discovered. The discovery not only points to possible ways to prevent or treat the condition, but could help explain why symptoms similar to those of long COVID are also commonly seen in a number of post-viral conditions and chronic inflammation. Although estimates are highly variable, as many as three in 10 people infected with SARS-CoV-2 could go on to develop long COVID, with symptoms including fatigue, ...

Regularly substituting meat for mycoprotein such as Quorn could help to lower bad cholesterol by 10-percent, which is comparable to switching to a Mediterranean or vegan diet. New research by the University of Exeter, published in Clinical Nutrition, also found substituting meat for Quorn reduces blood glucose and c-peptide concentrations associated with diabetes, cardiovascular disease and all-cause mortality. With one in six UK adults suffering from raised cholesterol, the findings indicate that mycoprotein - the high protein, high-fibre food source that’s the main ingredient in Quorn - could play a key role in ...

We need to stop designing new AI technology just because we can, causing people to adapt practices, habits and laws to fit the new technology; instead we need to design AI that fits exactly with what we need, according to human-centred AI advocates. Fifty experts from around the world have contributed research papers to a new book on how to make AI more ‘human-centred,’ exploring the risks — and missed opportunities — of not using this approach and practical ways to implement it. The experts come from over 12 countries, including Canada, France, Italy, Japan, New Zealand and the UK, and more ...

An important discovery from the NCI-MATCH precision medicine initiative is being published today in Clinical Cancer Research, a journal of the American Association for Cancer Research. Trastuzumab-pertuzumab, a drug combination approved by the US Food and Drug Administration (FDA) to treat patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer, shrunk tumors in patients with several other types of cancer with high levels of the HER2 gene. NCI-MATCH (Molecular Analysis for Therapy Choice) is one of the first ...

Obesity is a risk factor for stillbirth, and the risk increases as pregnancy advances to term, according to a large study published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.221450. The overall risk of stillbirth in pregnancy is approximately 0.4% in Canada. "Our findings suggest that an earlier delivery date may help reduce the risk of stillbirth for pregnant people with obesity," says lead author Dr. Naila Ramji, a high-risk pregnancy specialist in Fredericton, New Brunswick, and ...

An international study has shown for the first time how empathetic correction of misinformation among vaccine-hesitant patients can significantly improve attitudes towards vaccination – and potentially boost vaccine uptake. The research, led by the University of Bristol, also found this new style of communication could help build and maintain a positive relationship with health professionals, increasing trust and public confidence. With the UK currently facing a growing measles outbreak, fuelled by declining rates of the Measles, ...

The identification of an eleventh century Islamic astrolabe bearing both Arabic and Hebrew inscriptions makes it one of the oldest examples ever discovered and one of only a handful known in the world. The astronomical instrument was adapted, translated and corrected for centuries by Muslim, Jewish and Christian users in Spain, North Africa and Italy.   Dr Federica Gigante, from Cambridge University’s History Faculty, made the discoveries in a museum in Verona, Italy, and published them today in the journal Nuncius. Dr Gigante first came across a newly-uploaded ...

After one of the most intense cyclones in world history tore through the Pacific island of Tanna in Vanuatu, new research led by the University of Hawaiʻi at Mānoa showed the resilience of the island’s forests. In the Pacific islands, climate change is expected to increase the intensity and frequency of cyclones, causing huge potential risks to forests and the people who depend on them. In March 2015, Cyclone Pam touched down on the island of Tanna as the strongest Pacific island cyclone in history ...

The same weather system that led to the spread of the devastating Labor Day wildfires in 2020 brought record-breaking cold and early-season snowfall to parts of the Rocky Mountains. Now, new research from Portland State is shedding light on the meteorology behind what happened and the impacts of such an extreme weather event. “It’s really interesting to see such an amplified pattern result in opposing extremes in the Pacific Northwest and the Rocky Mountains,” said Emma Russell, a master’s student in geography ...
