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.

NIH study offers new evidence of early SARS-CoV-2 infections in US
A new antibody testing study examining samples originally collected through the National Institutes of Health's All of Us Research Program found evidence of SARS-CoV-2 infections in five states earlier than had initially been reported. These findings were published in the journal Clinical Infectious Diseases.

What makes us sneeze?
What exactly triggers a sneeze? A team led by researchers at Washington University School of Medicine in St. Louis has identified, in mice, specific cells and proteins that control the sneeze reflex. Better understanding of what causes us to sneeze -- specifically how neurons behave in response to allergens and viruses -- may point to treatments capable of slowing the spread of infectious respiratory diseases.

Brain cell membranes' lipids may play big role in Alzheimer's progression
Links between lipid imbalance and disease have been established, in which lipid changes increase the formation of amyloid plaques, a hallmark of Alzheimer's disease. This imbalance inspired researchers to explore the role of lipids comprising the cellular membranes of brain cells. In Biointerphases, the researchers report on the significant role lipids may play in regulating C99, a protein within the amyloid pathway, and disease progression.

Bending light for safer driving; invisibility cloaks to come?
Optical cloaking allows objects to be hidden in plain sight by guiding light around anything placed inside the cloak. While cloaking has been popularized in fiction, researchers in recent years have started realizing cloaks that shield objects from view by controlling the flow of electromagnetic radiation around them. In Journal of Applied Physics, researchers examined recent progress of developing invisibility cloaks that function in natural incoherent light and can be realized using standard optical components.
