The Emerald Ash Borer Network says that once the beetles reach their adult stage, the metallic green bugs will eat up foliage on ash trees – their only food source. But it’s the larvae that eat up the inner bark of ash trees and prevent nutrients and water from circulating.

Once that happens, Littleton officials said the tree that’s been attacked becomes structurally unsound and will die within just a few years.

It’s believed that the insects were introduced to the U.S. from Asia after tagging along on solid wood packing material, the network said. They were first discovered in the U.S. near Detroit in 2002, and have since expanded to at least 35 states as well as at least five Canadian provinces. Ash trees will typically lose most of their canopy within two years of an infestation and die within three to four years, the National Invasive Species Information Center says.

Standard immunotherapy procedures also employ intravenous injections loaded with NK cells to treat cancer but several limitations with this approach prevent it from delivering satisfying results. For instance, many NK cells lose their viability during the therapy and often fail to target the tumors, according to the researchers.

A new study conducted by researchers at Washington University School of Medicine in St Louis has explored the composition of gut bacteria in individuals in the earliest stage of Alzheimer’s disease. The research, which is published in Science Translational Medicine, not only identifies potential indicators of heightened dementia risk, but also offers prospects for developing microbiome-altering preventive treatments to combat cognitive decline.

Longevity. Technology: Previously, science has noted differences in the gut microbiomes of individuals with symptomatic Alzheimer’s compared with their healthy counterparts. However, the current study delves deeper, focusing on the gut microbiomes of individuals in the crucial pre-symptomatic phase. During this phase, individuals accumulate amyloid beta and tau proteins in their brains without exhibiting neurodegeneration or cognitive decline, which can persist for over two decades. Earlier diagnosis would enable people to access support and resources, plan for the future and well as onboarding treatments that could slow the progression of the disease. An idea of future numbers of patients would also allow health care infrastructure to be better prepared.

The researchers evaluated participants who volunteered at the Charles F and Joanne Knight Alzheimer Disease Research Center at Washington University, specifically selecting cognitively normal individuals. These participants provided samples of stool, blood, and cerebrospinal fluid, recorded their dietary habits, and underwent PET and MRI brain scans.

TUESDAY, July 6, 2023 (HealthDay News) — The widely used immunotherapy drug nivolumab (Opdivo) is safer and more effective in treating adults and children with advanced Hodgkin lymphoma than the targeted therapy now used as standard care is, new clinical trial results show.

Nivolumab outperformed the drug brentuximab vedotin (Adcetris), extending progression-free survival by 94% at one year compared to 86%, said lead researcher Dr. Alex Herrera, a hematologist-oncologist at City of Hope in Duarte, Calif.

Nivolumab also produced significantly fewer side effects than brentuximab vedotin, which was the first novel therapy developed for Hodgkin lymphoma, Herrera said in a presentation Sunday at the American Society for Clinical Oncology (ASCO) annual meeting in Chicago.

“A phonon represents the collective motion of an astronomical number of atoms,” Cleland says. “And they all have to work together in order to obey quantum mechanics. There was this question in the back of my mind, will this really work? We tried it, and it’s kind of amazing, but it really does work.”

Splitting a phonon

The team created single phonons as propagating wavepackets on the surface of a lithium niobate chip. The phonons were created and detected using two superconducting qubits, which were located on a separate chip, and coupled to the lithium niobate chip through the air. The two superconducting qubits were located either of the chip, with a two-millimetre-long channel between them hosting the travelling phonons.
