ROCHESTER, Minn. -- A study by researchers at Mayo Clinic Cancer Center has found that cancer patients diagnosed with COVID-19 who received care at home via remote patient monitoring were significantly less likely to require hospitalization for their illness, compared to cancer patients with COVID-19 who did not participate in the program. Results of the study were presented Friday, June 4, at the American Society of Clinical Oncology Annual Meeting and published in the Journal of Clinical Oncology.
Effector and killer T cells are types of immune cells. Their job is to attack pathogens and cancers. These cells can also go after normal cells causing autoimmune diseases. But, if harnessed properly, they can destroy cancer cells that resist treatment.
Scientists at St. Jude wanted to understand how these T cells are controlled. They looked at enhancers, sequences of DNA that when bound to certain proteins determine how genes are turned on or off.
Physicists in Israel have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams of atoms. University of Groningen physicist, Anupam Mazumdar, describes how the device could be adapted to use mesoscopic particles instead of atoms. This modification would allow for expanded applications. A description of the device, and theoretical considerations concerning its application by Mazumdar, were published on 28 May in the journal Science Advances.
Researchers in Lund, Copenhagen and Norwich have shown that harmful mutations present in the DNA play an important - yet neglected - role in the conservation and translocation programs of threatened species.
The COVID-19 pandemic forced instructors to adapt their courses for online learning. Laboratory courses were particularly difficult due to lack of access to specialized equipment for remote learners. To overcome this challenge, researchers from the University of Illinois Urbana-Champaign designed a laboratory exercise to teach students how to use micropipettes, through remote learning, using at-home kits.
A research group of the Department of Pharmacy and Biotechnology of the University of Bologna analyzed more than one million SARS-CoV-2 genome sequences. This analysis led to the identification of a new variant that, over the past weeks, has been spreading mostly in Mexico but has also been found in Europe. Their paper published in the Journal of Medical Virology presented the so-called "Mexican variant", whose scientific name is T478K. Like other strains, this presents a mutation in the Spike protein, which allows coronaviruses to attach to and penetrate their targeted cells.
Tiny algae in Earth's oceans and lakes take in sunlight and carbon dioxide and turn them into sugars that sustain the rest of the aquatic food web, gobbling up about as much carbon as all the world's trees and plants combined.
New research shows a crucial piece has been missing from the conventional explanation for what happens between this first "fixing" of CO2 into phytoplankton and its eventual release to the atmosphere or descent to depths where it no longer contributes to global warming. The missing piece? Fungus.
Though it might seem inanimate, the soil under our feet is very much alive. It's filled with countless microorganisms actively breaking down organic matter, like fallen leaves and plants, and performing a host of other functions that maintain the natural balance of carbon and nutrients stored in the ground beneath us.
Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying heat and electricity. While gold is a good conductor under any conditions, some materials have the property of behaving like metal conductors only if temperatures are high enough; at low temperatures, they act like insulators and do not do a good job of carrying electricity. In other words, these unusual materials go from acting like a chunk of gold to acting like a piece of wood as temperatures are lowered.
A new drug reduced tumor size in patients who have lung cancer patients with a specific, disease-causing change in the gene KRAS, a study found.
The results of the CODEBREAK 100 phase 2 clinical trial were presented June 4, 2021, at the American Society of Clinical Oncology (ASCO) annual meeting and published simultaneously in the New England Journal of Medicine. The efficacy and safety of the drug sotorasib, developed by Amgen Inc., was tested in patients with non-small-cell lung cancer (NSCLC) harboring a specific change, or mutation, in the DNA code for KRAS.

Bottom Line: The majority of surveyed Americans had an inadequate understanding of palliative care, and frequency of health care utilization was one determinant of knowledge.

Dogs may have earned the title "man's best friend" because of how good they are at interacting with people. Those social skills may be present shortly after birth rather than learned, a new study by University of Arizona researchers suggests.
Published today in the journal Current Biology, the study also finds that genetics may help explain why some dogs perform better than others on social tasks such as following pointing gestures.
WASHINGTON (June 3, 2021) - Nearly three-quarters of breast cancer patients (73%) report using at least one type of complementary medicine after cancer diagnosis, while oncologists believe that less than half (43%) of patients are using these approaches during cancer care. These and other findings from a national survey of oncologists and breast cancer patients were released in conjunction with the 2021 ASCO Annual Meeting. The study found that doctors report discussing integrative health with only about half of patients, leading patients to seek information outside the clinic.
