Researchers engineer insulin-producing cells activated by light for diabetes
- ScienceDaily
- 19/11/1 23:34
Researchers have transplanted engineered pancreatic beta cells into diabetic mice, then caused the cells to produce more than two to three times the typical level of insulin by exposing them to light. The light-switchable cells are designed to compensate for the lower insulin production or reduced insulin response found in diabetic individuals.
New printer creates extremely realistic colorful holograms

The secret behind crystals that shrink when heated
- ScienceDaily
- 19/11/1 19:39
Scientists have new experimental evidence and a predictive theory that solves a long-standing materials science mystery: why certain crystalline materials shrink when heated. Their work could have widespread application for matching material properties to specific applications in medicine, electronics, and other fields, and may even provide fresh insight into unconventional superconductors.
Chemotherapy sometimes set the stage for drug-resistant leukemia at relapse
- ScienceDaily
- 19/11/1 19:39
An international collaboration has identified therapy-induced, drug-resistance mutations in children with acute lymphoblastic leukemia who relapse.
Disordered proteins become stable, 'super-sticky' materials
- ScienceDaily
- 19/11/1 19:39
Biomedical engineers have demonstrated that they can create stable materials from engineered disordered proteins by altering the environmental triggers that cause them to undergo phase transitions. This discovery shines a light on previously unexplored behaviors of disordered proteins and allows researchers to create novel materials for applications in drug delivery, tissue engineering,...

- ScienceDaily
- 19/11/1 17:46
Researchers have created hybrid porous organic cages capable of high-performance quantum sieving that could help advance the deuterium/hydrogen isotope separation technologies needed for fusion power.
Being physically active can lower older adults' risk for dying
- ScienceDaily
- 19/11/1 17:46
A team of researchers looked more carefully at the relationship between death and physical exercise among older adults in Brazil (where the number of older adults grew 40 percent between 2002 and 2012).

- ScienceDaily
- 19/11/1 17:46
Micro-organisms living inside plant roots team up to boost the plant's growth and tolerance to stress.
Harvesting genes to improve watermelons
- ScienceDaily
- 19/11/1 17:46
An international team of researchers has taken a comprehensive look at the genomes of all seven species of watermelon, creating a resource that could help plant breeders increase the domestic fruit's quality and ability to thrive during an era of climate change.
Gene flow among distantly-related butterfly species
- ScienceDaily
- 19/11/1 16:16
Researchers analyzed the genomes of 20 butterfly species and found evidence that many butterflies -- including distantly related species -- have a surprisingly high amount of gene flow between them. The findings challenge conventional views about species, and indicate that hybridization may be a key process in the emergence of biological diversity.
Engineers develop new way to know liars' intent
