Three ways to travel at (nearly) the speed of light
One hundred years ago today, on May 29, 1919, measurements of a solar eclipse offered verification for Einstein's theory of general relativity. Even before that, Einstein had developed the theory of special relativity, which revolutionized the way we understand light. To this day, it provides guidance on understanding how particles move through space—a key area of research to keep spacecraft and astronauts safe from radiation.

Eating ultra-processed foods will make you gain weight. Here's the scientific proof
For four weeks, 20 healthy volunteers checked into a research center hospital and were served a variety of tempting meals: cinnamon french toast, stir-fry beef with broccoli and onions, turkey quesadillas and shrimp scampi. Researchers scrutinized everything that was eaten and came away with the first hard evidence to support a long-held suspicion: Heavily processed foods could be a leading factor in America's obesity epidemic.

Button batteries can rapidly damage stomach lining before symptoms appear
Damage to the lining of the stomach can occur quickly when children swallow button batteries; therefore, clinicians should consider prompt endoscopic removal, even when the child is symptom free and the battery has passed safely through the narrow esophagus, according to research presented at Digestive Disease Week (DDW) 2019. The recommendations represent a change from current practice of watching and waiting.

Dangerous pathogens use this sophisticated machinery to infect hosts
Gastric cancer, Q fever, Legionnaires' disease, whooping cough—though the infectious bacteria that cause these dangerous diseases are each different, they all utilize the same molecular machinery to infect human cells. Bacteria use this machinery, called a Type IV secretion system (T4SS), to inject toxic molecules into cells and also to spread genes for antibiotic resistance to fellow bacteria. Now, researchers at Caltech have revealed the 3-D molecular architecture of the T4SS from the human pathogen Legionella pneumophila with unprecedented details. This could in the future enable the development of precisely targeted antibiotics for the aforementioned diseases.

Nanoscale sculpturing leads to unusual packing of nanocubes
From the ancient pyramids to modern buildings, various three-dimensional (3-D) structures have been formed by packing shaped objects together. At the macroscale, the shape of objects is fixed and thus dictates how they can be arranged. For example, bricks attached by mortar retain their elongated rectangular shape. But at the nanoscale, the shape of objects can be modified to some extent when they are coated with organic molecules, such as polymers, surfactants (surface-active agents), and DNA. These molecules essentially create a "soft" shell around otherwise "hard," or rigid, nano-objects. When the nano-objects pack together, their original shape may not be entirely preserved because the shell is flexible—a kind of nanoscale sculpturing.

Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells
Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.

With more targeted therapies being approved each year for cancer, the development of drug resistance to these agents is a growing concern. It has often been assumed that drug resistance is due to the presence or development of additional genetic alterations; however, it is now clear that resistance mechanisms are more complicated. Researchers from Moffitt Cancer Center and Dana-Farber Cancer Institute have discovered a mechanism of drug resistance to Venetoclax, also known as ABT-199, a BCL-2 targeting drug commonly used to treat chronic lymphocytic leukemia and acute myeloid leukemia. Their findings, published in the journal Cancer Cell, also suggest a possible co-treatment strategy to overcome this resistance.

MR imaging evaluation of hepatocellular carcinoma treated with SBRT
Although arterial phase hyperenhancement (APHE) is a key feature of untreated or recurrent hepatocellular carcinoma (HCC), standard response assessment such as modified Response Evaluation Criteria in Solid Tumors (mRECIST) should be used with caution, particularly in the early phases after stereotactic body radiation therapy (SBRT) therapy, so as not to misinterpret treatment response, according to a study to be presented at the ARRS 2019 Annual Meeting, set for May 5-10 in Honolulu, HI.

Will MSC micropellets outperform single cells for cartilage regeneration?
Repair of cartilage injuries or defects is aided by the introduction of mesenchymal stem cells (MSCs), which can be incorporated into hydrogels to amplify their effects. In a new report, researchers directly compared chondrogenic induction by hydrogels that were prepared using MSCs either as single cell suspensions or as 100-500-cell micropellets. The study is published in Tissue Engineering.
