New studies identify how tuberculosis destroy the lungs and how to protect them
A "3D Culture System" developed by University of Southampton has closely replicated how cells infected with TB change in the human lung. Analytical evidence of these changes identified 7 key gene changes that cause damage in the lungs, from hundreds of thousands. A second trial showed that a common antibiotic, doxycycline, could help reverse these changes and speed up recovery.

Sequencing of wastewater can help monitor SARS-COV-2 variants
Viral genome sequencing of wastewater can provide an early warning system of emerging SARS-CoV-2 variants that is independent of investigations of identified clinical cases, according to a new study published in mSystems, an open-access journal of the American Society for Microbiology. In the study, researchers describe the detection and quantification of variant B.1.1.7, first identified in southeast England, in sewage samples from London, United Kingdom before widespread transmission of this variant was obvious from clinical cases.

Researchers develop more reliable rapid tests for COVID-19
Researchers at the University of Maryland School of Medicine (UMSOM) have developed two rapid diagnostic tests for COVID-19 that are nearly as accurate as the gold-standard test currently used in laboratories. Unlike the gold standard test, which extracts RNA and uses it to amplify the DNA of the virus, these new tests can detect the presence of the virus in as little as five minutes using different methods.

New AI model helps understand virus spread from animals to humans
A new model that applies artificial intelligence to carbohydrates improves the understanding of the infection process and could help predict which viruses are likely to spread from animals to humans. This is reported in a recent study led by researchers at the University of Gothenburg.

Hippos and anthrax
Hippopotamus aren't the first thing that come to mind when considering epidemiology and disease ecology. And yet these amphibious megafauna offered UC Santa Barbara ecologist Keenan Stears a window into the progression of an anthrax outbreak that struck Ruaha National Park, Tanzania, in the dry season of 2017.

Yale Cancer Center study reveals new pathway for brain tumor therapy
In a new study led by Yale Cancer Center, researchers show the nucleoside transporter ENT2 may offer an unexpected path to circumventing the blood-brain barrier (BBB) and enabling targeted treatment of brain tumors with a cell-penetrating anti-DNA autoantibody. The study was published today online in the Journal of Clinical Investigation Insight.

Scientists explain the crucial role of motor proteins in cell division
Proper chromosome segregation into two future daughter cells requires the mitotic spindle to elongate in anaphase. However, although some candidate proteins are implicated in this process, the molecular mechanism that drives spindle elongation in human cells has been unknown, until now! Researchers at the Croatian Ru?er Bokovi? Institute (RBI) have discovered the exact molecular mechanism of bridging microtubules sliding and its role in proper distribution of genetic material during cell division.

Rarest bee genus in North America is not so rare after all
Canadian researchers have discovered that a bee thought to be rarest in North America, as the only representative of its genus, is no more than an unusual specimen of a widespread species. They have reclassified the mystery bee, collected in Nevada in the 1870s, as an aberrant specimen of the California digger-cuckoo bee, a cleptoparasitic bee, with females that lay eggs in the nests of digger bees.

COVID-19 reinfection rate less than 1% for those with severe illness
A review of more than 9,000 US patients with severe COVID-19 infection showed less than 1% contracted the illness again, with an average reinfection time of 3.5 months after an initial positive test. Those are the findings from a study conducted by researchers from the University of Missouri School of Medicine and MU Health Care.
