De-escalating breast cancer therapy—can some patients be spared chemotherapy?
About one of every five breast cancers presents with high levels of HER2 proteins. Known as HER2-positive breast cancer, these tumors typically show an aggressive behavior—a greater likelihood of metastasis and relapse and decreased patient survival than HER2 negative types—and are physiologically dependent on the abundance of HER2. These findings prompted the question, if we take HER2 away from 'HER2-addicted' cancers, would cancer slow down?

Increased walking activity associated with long-term health benefits
Short term pedometer-based walking interventions can have long-term health benefits for adults and older adults, according to new research published in the open-access journal PLOS Medicine on 25 June. Tess Harris and colleagues from St George's University of London, UK and other institutions, conducted two trials of walking interventions which aimed to increase step count and physical activity. Not only did the investigators see sustained increases in physical activity at 3-4 years in the intervention group participants, they also noted fewer cardiovascular events and fractures.

Workers who are unpaid caregivers of older relatives struggle with unmet workplace needs
People who care for their elderly parents outside of their full-time jobs—and are unpaid for their help—experience considerable disruption of their workplace routines. Many are not getting employer support because it is not offered or because they do not feel able to use it, even if it is available, according to a Baylor University researcher.

Young women who smoke face highest risk of major heart attack
Smoking increases both men's and women's risk of a major heart attack at all ages, but women smokers have a significantly higher increased risk compared to men, especially women under 50 years old, according to a study in the Journal of the American College of Cardiology. Despite the increased risk, smokers can reduce their risk to that of a never smoker in as little as a month after quitting.

Researchers explain visible light from 2-D lead halide perovskites
Researchers drew attention three years ago when they reported that a two-dimensional perovskite—a material with a specific crystal structure—composed of cesium, lead and bromine emitted a strong green light. Crystals that produce light on the green spectrum are desirable because green light, while valuable in itself, can also be relatively easily converted to other forms that emit blue or red light, making it especially important for optical applications ranging from light-emitting devices to sensitive diagnostic tools.

Non-invasive, more precise preimplantation genetic test under development for IVF embryos
Selecting the best possible embryo to implant in a woman undergoing in vitro fertilization (IVF) is a complicated task. As success rates for IVF have improved, many clinics now implant a single embryo during an IVF cycle—with the goal of avoiding a multiple pregnancy—and the responsibility of selecting the embryo falls to the embryologist. To determine the quality and viability of an embryo, embryologists typically examine specific features of the embryos using a light microscope. In addition, specialists can use data from preimplantation genetic testing for aneuploidy (PGT-A), a test of whether cells from the embryo at the blastocyst stage have a normal or abnormal number of chromosomes. However, this crucial test carries the risk of false positives (which could lead to discarding a normal embryo) and false negatives (which could lead to transferring an embryo with a chromosomal abnormality).
