Potentially safer approach to opioid drug development
- ScienceDaily
- 21/8/24 19:53
Opioids are powerful painkillers but their use is hindered because patients become tolerant to them, requiring higher and higher doses, and overdoses can cause respiratory depression and death. A recent study contradicts existing thinking about how opioid drugs cause tolerance and respiratory depression, and suggests a new, balanced approach to developing safer analgesics.

- 21/8/24 19:53
Emergency room patients who were flagged by an artificial-intelligence algorithm for possibly having sepsis received antibiotics sooner and had better outcomes, according to a study conducted by physician-researchers.
Healthy sugar origin in stingless bee honey revealed
- ScienceDaily
- 21/8/24 19:53
Stingless bees are found throughout tropical and subtropical parts of the world and produce significantly less honey than their European honey bee counterparts (Apis mellifera) which are the world's major honey production species. However, stingless bee honey is highly prized as a specialty food, noted in Indigenous cultures for its medicinal properties, and attracts a high price. Now new research...
A novel gene involved in male infertility: ZFP541
- ScienceDaily
- 21/8/24 19:53
A new gene that controls the completion of meiosis in spermatogenesis has been discovered. Until now, details of the mechanism that inactivates the expression of genes involved in the meiotic program during spermatogenesis had not been clarified. The researchers believe that this may lead to an advancement in reproductive medicine, like identifying causes for infertility from azoospermia or...
Combination of mask wearing and keeping windows open is best for reducing COVID-19 risk in cars, new study finds
- ScienceDaily
- 21/8/24 19:53
New research has confirmed that keeping car windows open to draw in fresh air is key to reducing the risk of contracting the virus in vehicle environments -- but there are trade-offs.
Record-breaking lithium-metal cell
- ScienceDaily
- 21/8/24 19:53
A new type of lithium-metal battery reaches an extremely high energy density of 560 watt-hours per kilogram -- based on the total weight of the active materials -- with a remarkable stability. Researchers used a promising combination of cathode and electrolyte: The nickel-rich cathode enables storage of high energy per mass, the ionic liquid electrolyte ensures largely stable capacity over many...
Measuring how the Arctic responds to climate change
- ScienceDaily
- 21/8/24 19:53
The Arctic has been warming more than twice as fast as the rest of the planet. Meanwhile CO2 measurements show substantial increases in the amount of carbon absorbed into and emitted by Arctic plants and soil. Scientists assumed this was playing a large role in changes to the Arctic carbon cycle. But they were not able to measure carbon uptake and release independently. This study provides...
Green hydrogen: Focus on the catalyst surface
- ScienceDaily
- 21/8/24 19:53
Hydrogen produced from renewable energy sources with the help of electric power is deemed a key to the energy transition: It can be used to chemically store wind and solar energy in a CO2-neutral way. Researchers have studied water electrolysis processes on the surface of an iridium oxide catalyst.
There’s a bright side to being a ‘Debbie Downer’
- ScienceDaily
- 21/8/24 19:53
New research shows that keeping busy with a variety of activities can elicit both positive and negative emotions, and some of the relationship could depend on your age. A new study finds that engaging in diverse daily activities is associated with a diverse set of emotions.
Teaching an old dog new tricks: An existing drug opens new possibilities for treating childhood leukemia
- ScienceDaily
- 21/8/24 19:53
A new study has shown that the tumor-inhibiting gene TET2 is silenced in a large fraction of cases of acute lymphoblastic leukemia (ALL) in children. The scientists show that the gene can be reactivated by treatment with an existing drug, 5-azacytidine. The results suggest that 5-azacytidine may function as targeted therapy for ALL in children.

Evolutionary ‘arms race’ may help keep cell division honest
- ScienceDaily
- 21/8/24 19:53
Certain proteins may have evolved to tamp down 'cheating' during meiosis, the cell-division process that gives rise to eggs and sperm. While chromosomes can tip the scales in their favor of winding up in an egg, the team's new work identifies a mechanism that keeps the odds closer to 50-50, possibly reducing the likelihood that chromosomal abnormalities will arise during egg production.
