High-resolution microscopic images of the surface of dental enamel of lepidosauria, which is a subclass of reptile including monitor lizards, iguanas, lizards and tuatara, allow scientists to determine their dietary habits. The enamel wear patterns reveal significant differences between carnivores and herbivores, but also allow finer distinctions, such as between algae-, fruit-, and mollusk-eating species. These findings are the result of research by a team led by scientists at Johannes Gutenberg University Mainz (JGU). They point out that it has hitherto been difficult to make such fine distinctions between dietary behavior on the basis of dental or skeletal remains alone, particularly in the case of extinct species, because in many reptiles the teeth are of similar shape.

From one brain scan, more information for medical artificial intelligence
MIT researchers have devised a novel method to glean more information from images used to train machine-learning models, including those that can analyze medical scans to help diagnose and treat brain conditions.

Major HIV drug requires vigilance, study says
A study lead by researchers at the Institute of HIV Research, Medical Faculty of UDE and University Hospital Essen reports a potential toxicity of integrase inhibitors. Integrase inhibitors (INSTI) are a preferred drug for inclusion in anti-retroviral therapy regimens given its tolerability, efficacy and high resistance barrier. INSTI have been found to improve and prolong lives of millions of people living with HIV who suffer side-effects and resistance to treatment. However, recent laboratory data suggest that INSTI may not be as safe as suggested.

Kelly Latimer flies at the cutting edge of aviation—and soon, space
Kelly Latimer, 54, is a test pilot for Virgin Galactic and Virgin Orbit—two commercial space companies owned by British billionaire Richard Branson. For space tourism company Virgin Galactic, Latimer flies the giant, twin-fuselage aircraft known as WhiteKnightTwo, which carries a smaller spaceship at its belly to an altitude of up to 50,000 feet before the spaceship detaches and blasts off toward suborbital space. Latimer is also chief test pilot for Virgin Orbit, where she flies a modified 747 plane called Cosmic Girl. The plane carries a rocket under its left wing up to about 35,000 feet in the air, after which the rocket is released and falls for about four or five seconds before igniting and launching toward its intended orbit. Latimer is the only female test pilot out of a total of seven between the two companies.

Mystery of immunosuppressive drug's biosynthesis finally unlocked
Mycophenolic acid (MPA), discovered in 1893, was the first natural antibiotic to be isolated and crystallized in human history. Today, this fungal metabolite has been developed into multiple first-line immunosuppressive drugs to control immunologic rejection during organ transplantation and treat various autoimmune diseases.

A clear vision for cancer diagnosis
While reading an article about Sen. John McCain's glioblastoma diagnosis, Kavya Kopparapu was shocked to learn that the prognosis for this aggressive brain cancer has not improved over the past 30 years. With standard treatment, glioblastoma patients typically survive for only about 11 months after diagnosis, according to the American Brain Tumor Association.

SPFCNN-Miner: A new classifier to tackle class-unbalanced data
Researchers at Chongqing University in China have recently developed a cost-sensitive meta-learning classifier that can be used when the training data available is high-dimensional or limited. Their classifier, called SPFCNN-Miner, was presented in a paper published in Elsevier's Future Generation Computer Systems.
