Researchers from Bochum and Saarbrücken have detected security vulnerabilities, some of them serious, in several drones made by the manufacturer DJI. These enable users, for example, to change a drone’s serial number or override the mechanisms that allow security authorities to track the drones and their pilots. In special attack scenarios, the drones can even be brought down remotely in flight. The team headed by Nico Schiller of the Horst Görtz Institute for IT Security at Ruhr University Bochum, ...

New research led by Scripps Institution of Oceanography at UC San Diego has confirmed that coastal water pollution transfers to the atmosphere in sea spray aerosol, which can reach people beyond just beachgoers, surfers, and swimmers. Rainfall in the US-Mexico border region causes complications for wastewater treatment and results in untreated sewage being diverted into the Tijuana River and flowing into the ocean in south Imperial Beach. This input of contaminated water has caused chronic coastal water pollution in Imperial ...

The large number of oily wastewater discharges and oil spills are bringing about severe threats to environment and human health. Corresponding to this challenge, a number of functional materials have been developed and applied in oil-water separation as oil barriers or oil sorbents. These materials can be divided into two main categories which are artificial and natural. Natural materials such as green bio-materials are generally low cost and abundant with biological degradability, which are also regarded as promising alternatives for oil-water separation ...

Existing colour systems, such as RGB and CYMK, are all text-based and require a large range of values to represent different colours, making them difficult to compute and time-consuming to convert. Recently, researchers from City University of Hong Kong (CityU) made a breakthrough by inventing an innovative colour system, called “C235”, based on prime numbers, enabling efficient encoding and effective colour compression. It can unify existing colour systems and has the potential to be applied in various applications, like designing an energy-saving LCD system and colourizing DNA codons. Currently, ...

When it comes to venturing into and enjoying nature, forests are the people’s top choice – at least in Denmark. This is also reflected in the sales prices of properties with private forest. But beyond earnings potential, this first study of its kind, conducted by the University of Copenhagen, puts a price tag on the so-called amenity value of Danish private forests. Forests have a nearly therapeutic effect on humans. Perhaps that is why eight out of ten of Danes have wandered in the woods over ...

What are humans? What are animals? And what makes humans unique? The comparative psychologist Fumihiro Kano has set himself a life goal to answer those questions. On 28 February 2023 it was announced that the scientist from the Cluster of Excellence “Centre for the Advanced Study of Collective Behaviour” (CASCB) at the University of Konstanz will receive the Manfred Fuchs Prize from the Heidelberg Academy of Sciences and Humanities of the State Baden-Württemberg for his interdisciplinary work in animal behaviour research.

Sarcopenia is the decline of skeletal muscle mass with age, leading to loss of muscle strength (to move objects, shake hands etc.) and performance (walking and making other routine movements effectively). It involves chronic inflammation and is associated with cognitive alterations, heart disease and respiratory disorders. In short, it affects the quality of life, reducing independence and increasing the risk of injury, falls and even death. Sarcopenia affects 15% of adults over the age of 60 and 46% of those over 80. Sleep disorders are also common in these age groups. The aging ...

Bald eagles are often touted as a massive conservation success story due to their rebound from near extinction in the 1960s. But now a highly infectious virus may put that hard-fought comeback in jeopardy. Published in Nature’s Scientific Reports, new research from the University of Georgia showed highly pathogenic avian influenza, also known as H5N1, is killing off unprecedented numbers of mating pairs of bald eagles. “Even just one year of losses of productivity like we’ve documented regionally is very concerning and could have effects for decades to come if representative of broader regions,” said ...

Imagine if harried parents could get the scientific and clinical expertise of a pediatrician just by walking only a few steps next door. That’s the premise of a new podcast, The Pediatrician Next Door, by Dr. Wendy Hunter, M.D. She brings decades of experience in emergency and primary pediatric care to answer burning questions that parents are reluctant to ask. “In the emergency room, I saw a great many frustrated parents and their kids who didn’t always get their questions answered by their pediatrician because there just wasn’t time in the clinic,” said Dr. Hunter. “Or, they didn’t have access to their ...

Instead of special heart scans, physicians can use images of the chest captured months earlier, and for other reasons, to estimate patients’ risk of heart attack or death during several kinds of major surgeries, a new study shows.  Researchers at NYU Grossman School of Medicine analyzed existing computed tomography (CT) scans to estimate levels of hardened (calcified) fatty plaque deposits in the heart’s three largest blood vessels. They found that patients with greater buildup of this plaque had higher chances of developing serious health issues following surgery. Major surgeries, which usually ...

Researchers at Chalmers University of Technology in Sweden have developed a method for predicting fall accidents and cognitive illnesses such as Alzheimer’s disease by reading a person’s walking pattern with the aid of a radar sensor. The small sensor can be attached to furniture, walls and ceilings, both in the home and in a healthcare setting. “Our method is both precise and easy to use. It can help healthcare staff to carry out a more reliable risk analysis and tailor interventions to achieve a significant effect early on. Hopefully it can ...

New York, NY – March 02, 2023 – Despite COPD’s pervasiveness, it is generally assumed that the main instigator in its development is tobacco smoking. The 2023 Global Initiative for Chronic Obstructive Lung Disease or GOLD report is proposing a new definition of COPD, one that acknowledges the key pathogenic role of tobacco smoking but accounts for other factors that also contribute to COPD. The report is now available online in the American Journal of Respiratory and Critical Care Medicine. The GOLD 2023 report ...

Most adolescents and young adults have experienced bullying in some form, with about one-third of them experiencing cyberbullying, contributing to mental health concerns. Cyberbullying involves electronic communication such as texts, emails, online videos and social media, which has become increasingly problematic over the last few decades. Several reasons include the anonymity it allows, the fact that it is not as easily monitored, and that adolescents and young adults have easier access to devices. In an article published in the journal Primary Care Clinical ...

Scientists have analysed chemicals in the skin of southern right whales to give new insights into the animals’ distribution, as well as long-term environmental changes in the Southern Ocean. The research was published this week in Proceedings of the National Academy of Sciences (PNAS). [https://www.pnas.org/doi/10.1073/pnas.2214035120] The scientists from the US, Australia, Argentina, Brazil, South Africa, Europe, UK, and Aotearoa New Zealand measured the amounts of various carbon and nitrogen isotopes ...

Those living in unstable housing conditions, such as hostels or informal dwellings and those who had not completed post-secondary studies were more likely to contract HIV in South Africa, according to a new study from McGill University. A team of researchers based at the Research Institute of the McGill University Health Centre (RI-MUHC) has reported survey results that show socioeconomic factors play a critical role in the detection, transmission, and treatment of HIV in regions of South Africa. “We found that factors such as education and dwelling situations still impact ...

COLUMBUS, Ohio – There is much more to avian biodiversity in the United States than the number of different species living in a given region or community, but the diversity of birds’ ecosystem contributions – assessed through measures of their diet, body structure and foraging methods – are much tougher to study. And with hundreds of species migrating south for the winter and north for summer breeding, birds’ ecosystem function patterns change over space and time – creating a serious analytical challenge. But two scientists from The Ohio State University have ...

PULLMAN, Wash. – Adding evidence to the importance of early development, a new study links neutral maternal behavior toward infants with an epigenetic change in children related to stress response.  Epigenetics are molecular processes independent of DNA that influence gene behavior. In this study, researchers found that neutral or awkward behavior of mothers with their babies at 12 months correlated with an epigenetic change called methylation, or the addition of methane and carbon molecules, on a gene called NR3C1 when the children were 7 years ...

The iconic X-shaped organization of metaphase chromosomes is frequently presented in textbooks and other media. The drawings explain in captivating manner that the majority of genetic information is stored in chromosomes, which transmit it to the next generation. “These presentations suggest that the chromosome ultrastructure is well-understood. However, this is not the case”, says Dr. Veit Schubert from IPK’s research group “Chromosome structure and function”. Several models have been proposed to describe the higher-order structure of metaphase chromosomes based on data obtained using a range of molecular and microscopy methods. These models ...

New insights into the importance of early-life factors on lung health have been unveiled in the most comprehensive study of its kind, led by the Universities of Essex and Bristol. The researchers hope the findings, published today in the European Respiratory Journal, will pave the way to developing predictive tools for respiratory health and reduce healthcare inequality by targeting early-life interventions for people at higher risk. The study analysed data collected from 7,545 participants of Bristol’s Children of the 90s ...

Today, the Academic Freedom Index (AFI) project presents its Update 2023, providing an overview of the state of academic freedom in 179 countries. The decline in academic freedom affects over 50% of the world's population, approximately 4 billion people. The Index identifies 22 countries where universities and scholars experience significantly less academic freedom today than they did ten years ago. This includes democratic systems as well as autocratic countries. During the same period, academic freedom levels have only ...

A new paper in The Quarterly Journal of Economics, published by Oxford University Press, measures the overall impact of electoral campaigns and finds that televised debates have little effect on the formation of voter choice. Information received from other sources such as the media, political activists, and other citizens, matters more. Researchers and pundits have long debated the impact of political campaigns. One view is that the weeks immediately preceding elections are a crucial period. Campaign information can help voters assess the performance of incumbent politicians, compare the qualities and positions of all candidates, and perhaps even reconsider their policy preferences. But ...

Embargoed for Use Until: 3:30 p.m. PT/6:30 p.m. ET on Wednesday, March 1, 2023   Older Black men are likelier to die after surgery than others, particularly following elective procedures, new UCLA research suggests   Older Black men have a higher chance of dying within 30 days of surgery than do Black women and white men and women – with their odds of death 50% higher after elective surgery compared with white men.   The researchers suspect that the “especially high cumulative amounts of stress and allostatic load” that Black men face the U.S. may significantly contribute to declines in their physical health, they write.   “While ...

Black men have a higher death rate within 30 days of surgery compared with any other subgroup of race and sex, finds a study of adults in the United States published in The BMJ. This inequality in death rate was mainly observed for elective, or planned, surgeries, where the death rate for Black men was 50% higher than that of White men.  The researchers say further research is needed to understand better the “factors contributing to this higher mortality rate among Black men after elective surgery.” In previous studies, racial inequities in surgical care and outcomes, including a higher death rate following surgery for Black patients, have been well documented.  However, ...
