Why are some birds more intelligent than others?
- ScienceDaily
- 22/8/2 23:58
If you've ever seen a grackle steal your dog pellets or a starling peck open a garbage bag, you get a sense of that some birds have learned to take advantage of new feeding opportunities -- a clear sign of their intelligence. Scientists have long wondered why certain species of birds are more innovative than others, and whether these capacities stem from larger brains (which intuitively seems...

Researchers report that a gene therapy approach, developed measurably delayed disease onset in humanized mouse and rat models of familial ALS, an inherited form of the disease that runs in families.
Affordable and sustainable alternative to lithium-ion batteries proposed
- ScienceDaily
- 22/8/2 19:29
Concerns regarding scarcity, high prices, and safety regarding the long-term use of lithium-ion batteries has prompted a team of researchers to propose a greener, more efficient, and less expensive energy storage alternative.
Computer modelling aims to inform restoration, conservation of coral reefs
- ScienceDaily
- 22/8/2 19:29
A research team has created a computer modelling program to help scientists predict the effect of climate damage and eventual restoration plans on coral reefs around the globe. This is a critical objective because climate change is killing many coral species and can lead to the collapse of entire coral reef ecosystems, according to researchers.
Optical imaging of dynamic interactions between molecules in a cell
- ScienceDaily
- 22/8/2 18:17
Researchers develop the 'photoswitching fingerprint analysis'. A unique technology that for the first time allows the analysis of molecular processes and the regulation of individual proteins in living cells with sub-10 nm spatial resolution. The application ranges from biological to medical research.
Researchers create biosensor by turning spider silk into optical fiber
- ScienceDaily
- 22/8/2 18:17
Researchers have harnessed the light-guiding properties of spider silk to develop a sensor that can be used to determine concentrations of fructose, sucrose and glucose sugars based on changes in a solution's refractive index. The new light-based sensor might one day be useful for measuring blood sugar and other biochemical analytes.
Early physical therapy associated with less health care resource use for patients with acute lower back pain
- ScienceDaily
- 22/8/2 18:17
Early initiation of physical therapy (PT) for U.S. patients with acute lower back pain (LBP) was associated with less health care resource use in the first month and the first year after the initial onset of symptoms, according to a new study.
Flare-ups of gout are linked to heart attack and stroke
- ScienceDaily
- 22/8/2 18:17
Experts have found that the risk of heart attacks and strokes temporarily increases in the four months after a gout flare. The research showed that gout patients who suffered from a heart attack or stroke were twice as likely to have had a gout flare in the 60 days prior to the event, and one and a half times more likely to have a gout flare in the 61-120 days prior.

Newts unleashed: Limb muscle regeneration needs metamorphosis and body growth
- ScienceDaily
- 22/8/2 16:50
Researchers have found that muscle fibers in Japanese Fire-bellied Newts have an intrinsic ability to dedifferentiate, or reprogram, and contribute to limb regeneration. The results indicate that changes in the niche (the environment outside the cell) during metamorphosis and body growth are needed to unleash this ability. This study provides a key basis for future research on dedifferentiation,...
How ADAR1 mutation leads to self-destructive inflammation
- ScienceDaily
- 22/8/2 16:50
A new study shows how mutation of the ADAR1 gene sets off biochemical pathways that produce an autoimmune response that harms the developing brain and other areas of the body. The normal form of the gene produces an RNA-editing enzyme to stop abnormal immune activation when the body misidentifies its own RNA. Mutations in ADAR1 are common in people of northern European descent. When they co-occur...
