Contact tracing and targeted insecticide spraying can curb dengue outbreaks

Contact tracing -- a process of identifying everyone who has come into contact with those infected by a particular disease -- combined with targeted, indoor spraying of insecticide can greatly reduce the spread of the mosquito-borne dengue virus, finds a study.

Why is pancreatic cancer so hard to treat? Stroma provides new clues

Added: 23.02.2017 21:57 | 0 views | 0 comments

Why are pancreatic tumors so resistant to treatment? One reason is that the 'wound'-like tissue that surrounds the tumors, called stroma, is so dense, likely preventing cancer-killing drugs from reaching the tumor. A team has now discovered heterogeneity in the fibroblast portion of the stroma, opening up the possibility of targeted treatment.

[Perspective] Why tolerance invites resistance

Added: 23.02.2017 19:56 | 0 views | 0 comments

Bacteria use two strategies to avoid being killed by antibiotics: resistance and tolerance. Resistance mechanisms such as destruction of a drug or modification of its target allow bacteria to grow in the presence of antibiotics. Tolerance is a property of dormant, nongrowing bacterial cells in which antibiotic targets are inactive, allowing bacteria to survive. The two phenomena are mechanistically distinct and assumed to be unrelated. On page 826 of this issue, Levin-Reisman et al. (1) show that tolerance nevertheless leads to resistance.

[Report] Bumblebees show cognitive flexibility by improving on an observed complex behavior

Added: 23.02.2017 19:56 | 0 views | 0 comments

We explored bees’ behavioral flexibility in a task that required transporting a small ball to a defined location to gain a reward. Bees were pretrained to know the correct location of the ball. Subsequently, to obtain a reward, bees had to move a displaced ball to the defined location. Bees that observed demonstration of the technique from a live or model demonstrator learned the task more efficiently than did bees observing a “ghost” demonstration (ball moved via magnet) or without demonstration. Instead of copying demonstrators moving balls over long distances, observers solved the task more efficiently, using the ball positioned closest to the target, even if it was of a different color than the one previously observed. Such unprecedented cognitive flexibility hints that entirely novel behaviors could emerge relatively swiftly in species whose lifestyle demands advanced learning abilities, should relevant ecological pressures arise.

Anti-aging gene identified as a promising therapeutic target for older melanoma patients

Added: 23.02.2017 16:47 | 0 views | 0 comments

An anti-diabetic drug can inhibit the growth of melanoma in older patients by activating an anti-aging gene that in turn inhibits a protein involved in metastatic progression and resistance to targeted therapies for the disease, new research indicates.
