The sweetpotato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), is a polyphagous pest recognized as composed of several cryptic or sibling species. The Middle East-Asia Minor 1 (MEAM1) and the Mediterranean (MED) putative species are invasive and destructive worldwide. The MEAM1 is established throughout the United States, while MED is documented in 27 states.

Sufficient sleep is essential for individual well-being. Inadequate sleep has been shown to have significant negative impacts on our attention, cognition, and mood. The measurement of sleep from in-bed physiological signals has progressed to where commercial devices already incorporate this functionality.

Article Synopsis
  • Chronic pain is linked to symptoms of depression and anxiety, and management programs, whether in-person or online, can help adults cope with these issues; sudden gains are quick, meaningful reductions in symptoms that may influence treatment results!* -
  • A study analyzed data from 338 adults in an 8-week online pain management program, finding that similar rates of sudden gains in depression (22%) and anxiety (24%) were seen, mostly occurring between the first two weeks of treatment, regardless of the level of therapist guidance!* -
  • The findings indicate that sudden gains in mood symptoms do not lead to better post-treatment outcomes for those with chronic pain, suggesting that a higher initial severity of symptoms is the key factor rather than therapist support

R-loops (RNA-DNA hybrids with displaced single-stranded DNA) have emerged as a potent source of DNA damage and genomic instability. The termination of defective RNA polymerase II (RNAPII) is one of the major sources of R-loop formation. 5'-3'-exoribonuclease 2 (XRN2) promotes genome-wide efficient RNAPII termination, and XRN2-deficient cells exhibit increased DNA damage emanating from elevated R-loops.

The efficient breakage of one cell or a concentration of cells for releasing intracellular material such as DNA, without damaging it, is the first step for several diagnostics or treatment processes. As the cell membrane is easy to bend but resistant to stretching, the exposure of the cell to a shear rate during a short period of time can be sufficient to damage the membrane and facilitate the extraction of DNA. However, how to induce high shear stresses on cells in small microliter volumes samples has remained an elusive problem.
