A ball, a saddle, or a flat plate. The curvature of biomaterials inhibits or stimulates bone cells to make new tissue. This is what TU Delft engineers show in research published on Friday, 3rd of March in Nature Communications. This study of geometries could be an important step in research into repairing damaged tissues. Living cells can perceive and respond to the geometry of their environment. ‘Cells sense and respond to the geometry of the surfaces they are exposed to. Depending on their curvature, surfaces can either encourage cells to create new tissue or prevent them from doing so,’ says Amir Zadpoor, ...

Human papillomavirus (HPV) vaccination rates among eligible veterans and active-duty military are half that of their civilian peers, putting them at greater risk of HPV-related cancers. That’s according to a new study published today in JAMA Oncology that provides the first national estimate of HPV vaccination rates in this population. “Our findings should serve as a call to action to the Department of Defense and the Veterans Health Administration to advocate that their service members get vaccinated,” said senior author José P. Zevallos, ...

Over the past decade, human papillomavirus (HPV) has increasingly been identified as a significant cause of certain head and neck cancers – for example, evidence suggests it causes 70% of oropharyngeal cancers in the United States. Further, over the past three decades, incidence of HPV-driven cancers has increased substantially worldwide and in the U.S. While there are well-established screening tools, as well as vaccines, for HPV-driven cancers such as cervical cancer, there are fewer resources for HPV-driven head and neck cancers. As a result, researchers are working with a sense of urgency to develop innovative ...

Infrared spectroscopy is a non-invasive tool to identify unknown samples and known chemical substances. It is based on how different molecules interact with infrared light. You may have seen this tool at airports, where they screen for illicit drugs. The technique has many applications: liquid biopsy, environmental gas monitoring, contaminant detection, forensic analyses, exoplanet search, etc. But the traditional infrared spectroscopy methods provide low (temporal) resolution data. They are usually only applied for static samples because spectral data acquisition is a slow process. Detecting fast-changing phenomena ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have successfully threaded atoms of indium metal in between individual fibers in bundles of transition metal chalcogenide nanofibers. By steeping the bundles in indium gas, rows of atoms were able to make their way in between the fibers to create a unique nanostructure via intercalation. Through simulations and resistivity measurements, individual bundles were shown to have metallic properties, paving the way for application as flexible nanowires in nanocircuitry.   Atomic wires of transition metal chalcogenides (TMCs) ...

Healthcare providers (HCP) at three Miami hospitals during the height of the Covid crisis, who practiced the Transcendental Meditation technique (TM), showed a rapid and highly significant reduction in stress-related burnout symptoms such as somatization, depression, anxiety, sleep disturbances, and emotional exhaustion, as well as significant improvement in mental well-being, compared to a parallel matched lifestyle-as-usual group (LAU), according to a new study published today in PLOS ONE. A total of 65 healthcare providers at the three Miami hospitals (Baptist, ...

The first piece of a series of concrete structures was lowered into the water off the coast of Miami Beach on Wednesday morning, a massive crane on the deck of a floating barge hoisting the unit into the air and sinking it to the seabed.  During the next six hours, crewmembers aboard the barge would repeat that process until the structures, some stacked on top of each other, were settled on the seafloor, 14 feet below the surface.  To casual observers onshore, the daylong operation might have seemed routine. But this maritime activity was hardly run-of-the-mill.  In ...

Oil palm trees are the most productive oil crop and global demand is increasing. However, their productivity is due to conventional management practices including high fertilizer usage and herbicide application, resulting in severe environmental damage. A new study by an international, multidisciplinary research team led by the University of Göttingen, shows that shifting to mechanical weeding and reducing fertilizer usage lead to significant increases in both ecosystem multifunctionality and profit. The scientists compared different environmental measures and economic indicators in mechanical weeding, herbicide application, and combinations of these with high and reduced fertilizer ...

A team of researchers has developed a machine learning model that draws from the contents of news articles to effectively predict locations that face risks of food insecurity. The model, which could be used to help prioritize the allocation of emergency food assistance across vulnerable regions, marks an improvement over existing measurements.  “Our approach could drastically improve the prediction of food crisis outbreaks up to 12 months ahead of time using both real-time news streams and a predictive model that is simple to interpret,” says Samuel Fraiberger, a visiting researcher at ...

Cancer cells have an innate randomness in their ability to respond to chemotherapy, which is another tool in their arsenal of resisting treatment, new research led by the Garvan Institute of Medical Research shows. Understanding why some tumour cells become resistant to chemotherapy is a core challenge in cancer research, as chemotherapy is still a frontline treatment for most cancers. The new research shows that tumour cells from neuroblastoma – cancer that develops in the body’s ‘fight or flight’ sympathetic nervous system – can move between states of responding, or not, to chemotherapy. “We showed there is ‘noise’ in the process of cell ...

As a social media user, you can be eager to share content. You can also try to judge whether it is true or not. But for many people it is difficult to prioritize both these things at once. That’s the conclusion of a new experiment led by MIT scholars, which finds that even considering whether or not to share news items on social media reduces people’s ability to tell truths from falsehoods. The study involved asking people to assess whether various news headlines were accurate. But if participants were first asked whether they would share that content, they were 35 percent worse at telling truths from ...

The researchers discovered evidence of horse riding by studying the remains of human skeletons found in burial mounds called kurgans, which were between 4500-5000 years old. The earthen burial mounds belonged to the Yamnaya culture. The Yamnayans had migrated from the Pontic-Caspian steppes to find greener pastures in today´s countries of Romania and Bulgaria up to Hungary and Serbia. Yamnayans were mobile cattle and sheep herders, now believed to be on horseback. “Horseback-riding seems to have evolved not long ...

Researchers at UCL and University of Ghana have successfully predicted whether children have anaemia using only a set of smartphone images. The study, published in PLOS ONE, brought together researchers and clinicians at UCL Engineering, UCLH and Korle Bu Teaching Hospital, Ghana to investigate a new non-invasive diagnostic technique using smartphone photographs of the eye and face. The advance could make anaemia screening more widely available for children in Ghana (and other low- and middle-income countries) where ...

A recent study on the genetic makeup of grapevine has revealed fascinating insights into its domestication and evolution. The study, published in the journal Science, suggests that the harsh climate during the Pleistocene era resulted in the fragmentation of wild ecotypes, which paved the way for the domestication of grapevine about 11,000 years ago in the Near East (Israel) and the Caucasus. The research team sequenced the genomes of 3525 grapevine accessions (2503 V. vinifera (domesticated) and 1022 V. sylvestris (wild) accessions of grapevine, to identify the genetic changes that occurred during domestication and evolution of grapevine in Euro-Asia. According to the study, ...

Modifying inflorescences with higher grain capacity is vital for crop grain production. One recurring target is to select inflorescences with more branches or floral structures. Prominent examples include genes affecting floral identity or meristem determinacy, for which natural or induced variants profoundly change floral primordium number. Yet for temperate cereal crops, such as wheat and barley, excessive floral structures can result in a degeneration penalty due to the indeterminate nature of meristems. On the other hand, the manifestation of this reproductive potential can be accentuated by environmental ...

For older adults with clinical depression that has not responded to standard treatments, adding the drug aripiprazole (brand name Abilify) to an antidepressant they’re already taking is more effective than switching from one antidepressant to another, according to a new multicenter study led by Washington University School of Medicine in St. Louis. Aripiprazole originally was approved by the FDA in 2002 as a treatment for schizophrenia but also has been used in lower doses as an add-on treatment for clinical depression ...
