How x-rays could make reliable, rapid COVID-19 tests a reality
Vaccines are turning the tide in the pandemic, but the risk of infection is still present. Instant at-home tests would help us return to normal, but current options aren't very accurate. A new discovery could help get reliable tests on the market.

Study confirms origin of vervet monkeys living near an urban airport for decades
Scientists have confirmed the species and origin of a colony of wild African vervet monkeys that landed in Dania Beach more than 70 years ago. They escaped from the Dania Chimpanzee Farm in 1948 and settled in a thick mangrove forest near the Fort Lauderdale-Hollywood International Airport in South Florida. The facility acted as a zoo and also provided primates imported from Africa as research subjects in the development of the polio vaccine and other medical research.

Icing muscle injuries may delay recovery
In sports, it is common practice to apply ice to sore muscles in order to reduce inflammation. However, a Kobe University-led study on mice has revealed that icing severe muscle injuries may actually prolong the healing process. The results indicate that cooling the injury makes it difficult for macrophages to enter the damaged cells in order to repair them.

Postsynaptic density consisting of tubulin-based postsynaptic density lattice backbone
A research group led by Specially appointed professor, Dr. Tatsuo Suzuki of Shinshu University's School of Medicine developed a new purification protocol for Postsynaptic density (PSD) lattice, a core structure of the PSD of excitatory synapses in the central nervous system. The components of the PSD lattice were identified by comprehensive shotgun mass spectrometry, and categorized as either minimum essential component (MEC) or non-MEC proteins. Tubulin was found to be a major component of ...

Gut check
Researchers identify links between genetic makeup of bacteria in human gut and several human diseases. Clusters of bacterial genes present in conditions including cardiovascular illness, inflammatory bowel disease, liver cirrhosis, and cancer. Work brings scientist closer to developing tests that could predict disease risk or identify disease presence based on a sampling of the genetic makeup of a person's microbiome.

Synaptic transmission: Not a one-way street
When neuroscientists at the Institute of Science and Technology (IST) Austria analyzed the exact properties of nerve connections in the brain, they made a startling observation: At a key connection, or synapse, messages are sent against the usual stream of information. The study, published in the journal Nature Communications, reports that the signal glutamate likely plays a role in this unusual transmission.

How to become 'ant-i-social'
In the insect world, there are rare instances of ants shrugging off their societal duties to become free-loading parasites amongst their free-living relatives. Now, in a new study, an international collaboration of researchers teamed up to discover and collect these rare ant social parasites. Together, for the first time, they have obtained and analyzed the full DNA genome sequences of three rare "social parasite" leaf-cutting ant species (called Acromyrmex inquilines) to better understand the differences between them and their respective host species.

Scientists debut most efficient 'optical rectennas,' devices that harvest power from heat
For decades, researchers have theorized that optical rectennas could sit on everything from bakery ovens to dirigibles flying high above Earth to harvest waste heat and turn it into electricity. But to date, those goals have remained elusive. Now, engineers have unveiled the most efficient optical rectennas yet.

Researchers announce new discovery to evaluate tuberculosis treatments
A new study published in Nature Communications provides an important new way to compare the effectiveness of tuberculosis treatments. Their new measure, the rRNA synthesis (RS) Ratio can enable more intelligent design and evaluation of candidate drug combination regimens, accelerating the development of treatments that can cure tuberculosis faster. This has crucial implications for combatting the global tuberculosis epidemic.

Portable, affordable, accurate, fast: Team invents new COVID-19 test
A new coronavirus test can get accurate results from a saliva sample in less than 30 minutes, researchers report in the journal Nature Communications. Many of the components of the hand-held device used in this technology can be 3D-printed, and the test can detect as little as one viral particle per 1-microliter drop of fluid.

A new meta-analysis supports elective revascularization and medical therapy
The ISCHEMIA trial found no significant difference between an invasive vs. a conservative strategy in patients with chronic coronary syndromes and moderate to severe ischemia at a mean of 3.2 years. However, the cumulative difference in the estimates of cardiac death between the invasive and conservative strategies tended to increase numerically over time (e.g., 0.3% in favor of the invasive strategy at 2 years and 1.3% at 5 years)...

Cool AMI EU pivotal trial final results after trial discont. following ad interim analysis
Results of the interim analyses performed after 12 months in the first 111 patients enrolled in phase II Cool AMI trial evaluating safety and effectiveness of systemic therapeutic hypothermia as an adjunctive therapy in anterior STEMI undergoing PCI as compared to PCI only. Analyses showed significant differences among treatment groups, including longer randomization-to-balloon time and total ischemic time in treatment arm, justifying premature trial discontinuation.
