Researchers find effective combination of therapies for managing mitochondrial disease
Researchers have demonstrated how one combination of therapies may be beneficial for patients with mitochondrial respiratory chain disorders. This preclinical research paves the way to develop more tailored treatment options for patients with inherited mitochondrial disease and acquired energy disorders.
Rice plant resists arsenic
The agricultural cultivation of the staple food of rice harbours the risk of possible contamination with arsenic that can reach the grains following uptake by the roots. A Chinese-German research team of Heidelberg University and Nanjing Agricultural University studied over 4,000 rice variants and discovered a plant that resists the toxin as well as contains a large amount of the trace element...
Saarbruecken chemists develop variety of industrially important synthetic process
Olefin metathesis is a chemical process for the formation of carbon-carbon double bonds (C=C) that predominantly finds application in the petrochemical industry, in polymer synthesis and in the manufacture of pharmaceuticals. Up until now, this metathesis reaction was limited to alkenes (olefins) with C=C bonds. Chemists at Saarland University have now developed a means of getting double bonds of...
Scientists develop elements for the future electronics
Researchers are developing thin films, the elements for biomolecular electronics. Scientists believe that biological macromolecules such as nucleic acids, proteins, amino acids can become a promising material for modern electronics. It obtains several unique properties, for example, the self-organization ability, which is why the molecules can be assembled into certain structures, for example,...
Scientists use forest color to gauge permafrost depth
Researchers have developed a remote sensing method of measuring the depth of permafrost by analyzing vegetation cover in boreal ecosystems.
Secrets of sealed 17th century letters revealed by dental X-ray scanners
In a world first, an international team of researchers has read an unopened letter from Renaissance Europe - without breaking its seal or damaging it in any way.
Sequential treatment with immunotherapy and checkpoint inhibitors prolongs anti-tumor activity
In a new article published in Cancer Immunology Research, the Moffitt team shows that sequential administration of immunotherapy followed by targeted therapy prolongs anti-tumor responses in preclinical models and may be a potential treatment option for patients with advanced melanoma.
Shade-grown coffee could help save birds, if only people knew about it
The message about the bird-conservation benefits of shade-grown coffee may not be getting through to the people most likely to respond--birdwatchers. A team of researchers from the Cornell Lab of Ornithology and Virginia Tech surveyed birdwatchers to learn if they drank shade-grown coffee and, if not, why not.
Skipping mammogram increases risk of death from breast cancer
Attendance at regular mammography screening substantially reduces the risk of dying from breast cancer, according to a large study of over half a million women. Researchers said women who skip even one scheduled mammography screening before a breast cancer diagnosis face a significantly higher risk of dying from the cancer.
Smaller, faster, greener
Every aspect of modern computing, from the smallest chip to the largest data center comes with a carbon price tag. The tech industry and the field of computation as a whole have focused on building smaller, faster, more powerful devices -- but few have considered their overall environmental impact. SEAS researchers are trying to change that by challenging the field to add carbon footprint to the...
Sniffing in the name of science
It is often difficult to find out exactly where the individual species can be found and how their populations are developing. According to a new overview study published in Methods in Ecology and Evolution by Dr Annegret Grimm-Seyfarth from the UFZ and her colleagues, specially trained detection dogs can be indispensable in such cases. With the help of these dogs, the species sought can usually be...
Soft and comfortable e-textiles that can be used to measure photoplenthysmography
Advances in wearable devices have enabled e-textiles, which fuse lightweight and comfortable textiles with smart electronics, and are garnering attention as the next-generation wearable technology. In particular, fiber electronic devices endowed with electrical properties, while retaining the specific characteristics of textiles, are key elements in manufacturing e-textiles. A team of researchers...
Space hurricane observed for the first time
Hurricanes are known to occur in the lower atmosphere of Earth and even other planets, but had never before been detected in the upper atmosphere. An international team of scientists made the unprecedented discovery during retrospective analysis of satellite observations. The hurricane occurred during surprisingly low geomagnetic activity, and suggests they could occur in the upper atmosphere of...
Study explores link between forestry management and pesticides in aquatic species
Pesticides used in forestry may threaten species in downstream rivers and estuaries, but little is known about the extent to which this occurs. A new study by researchers at Portland State University found mussels, clams and oysters in watersheds along the Oregon Coast are exposed to pesticides used in managing forests. The results of this study, published in the journal Toxics, have implications...
Study highlights pitfalls associated with 'cybervetting' job candidates
A recent study of how human resources professionals review online information and social media profiles of job candidates highlights the ways in which so-called "cybervetting" can introduce bias and moral judgment into the hiring process.
Study of severe pediatric COVID-19 syndrome highlights differences in immune responses to SARS-CoV-2
A new study of patients with Multisystem Inflammatory Syndrome in Children (MIS-C), a rare but severe complication of COVID-19 in children, reveals distinct immune features of COVID-19 not seen in adults that may clue scientists in to why SARS-CoV-2 infection manifests differently in children compared with adults.
Study points to the challenges of harvest-time weed seed controls in Pacific Northwest
A recent article in the journal Weed Science explores whether harvest-time controls would be effective against downy brome, Italian ryegrass, feral rye and rattail fescue - weeds that compete with winter wheat in the Pacific Northwest.
Study reveals impact of lockdown on violence in a UK capital city
The first UK COVID-19 lockdown saw a 'rapid and sustained' fall in violence outside the home in the Welsh capital city, a new study led by Cardiff University has shown
Study: Using a warmer tone in college syllabi makes students more likely to ask for help
College course syllabi written in a warm, friendly tone are more likely to encourage students to reach out when they are struggling or need help, a new study from Oregon State University found.
The conditions of 70% of people with chronic pain have worsened during the pandemic
A UOC study shows that factors such as job insecurity, worrying about the future and fear of contagion may have a negative impact on people living with pain
The expanding possibilities of bio-based polymers
In a paper published in ACS Sustainable Chemistry & Engineering, researchers from the Kleij group present a new route to prepare biobased polyesters with tuneable properties. The researchers are building upon the multifunctional structure of the terpene β-elemene: three double bonds which have distinct reactivity, allowing to selectively transform these bonds and thus tweaking the...
The implications of swollen lymph nodes following COVID-19 vaccination
When patients undergo imaging tests for various medical reasons shortly after receiving a COVID-19 vaccine in the arm, their tests may show swollen lymph nodes in the armpit area. Radiologists at Massachusetts General Hospital say that this is usually a normal finding, and they offer recommendations on when and if follow-up tests are needed. The team has published an approach to help avoid delays...
