A novel imaging technique that uses a synthesized form of scorpion venom to light up brain tumors has shown promise in a clinical trial.
Study shows one third of statin patients don't reach healthy levels of 'bad' cholesterol
Science Daily - 9 May 2019 20:27
Using electronic health records from the Indiana Network for Patient Care, a new population health study of entire state found that one third of statin patients don't reach healthy levels of 'bad' cholesterol. Results sh...
Using an X-Ray Laser, Researchers Make the Loudest Underwater Sound
Physics Buzz - 9 May 2019 15:45
Researchers from SLAC National Accelerator Laboratory have produced an underwater sound so intense that it rivals the Earth-shaking roar of a rocket launch. "It is just below the threshold where [the sound] would boil th...
A link between mitochondrial damage and osteoporosis
Science Daily - 9 May 2019 21:34
In healthy people, a tightly controlled process balances out the activity of osteoblasts, which build bone, and osteoclasts, which break it down. Damage to cells' mitochondria can make that process go awry, according to ...
A deep-dive into the impact of arthritis drugs on gene expression
Science Daily - 9 May 2019 20:28
A new computational framework has revealed key differences between four rheumatoid arthritis medications and their impact on biological pathways in mice.
How the dengue virus replicates in infected cells
Science Daily - 9 May 2019 20:28
The nonstructural protein 1 (NS1) of the dengue virus interacts with another viral protein called NS4A-2K-4B to enable viral replication, according to a new study.
New HIV vaccine strategy 'pumps' the immune system
Science Daily - 9 May 2019 20:28
Scientists have found that slowly releasing an HIV vaccine could prompt the body to make more powerful antibodies against the virus.
New model of measles-elimination progress may help target vaccination efforts
Science Daily - 9 May 2019 20:28
A country's progress towards measles elimination can be mapped on a 'canonical path' that in turn can guide vaccination strategies, according to a new study.
Back to the sources of neural diversity
Science Daily - 9 May 2019 20:27
By deciphering the genetic programs of neurons of the cerebral cortex, researchers have unraveled the mechanisms controlling the genesis of cells in one of the most essential parts of our brain.
Personalized 'eye-in-a-dish' models reveal genetic underpinnings of macular degeneration
Science Daily - 9 May 2019 18:51
Using stem cells derived from six people, researchers recapitulated retinal cells in the lab. This 'eye-in-a-dish' model allowed them to identify genetic variants that cause age-related macular degeneration, a common cau...
Fooling nerve cells into acting normal
Science Daily - 9 May 2019 18:51
Scientists have discovered that a neuron's own electrical signal, or voltage, can indicate whether the neuron is functioning normally. If that voltage is absent, scientists say everything is 'out of whack.'
A cautionary tale for researchers working on selective drug delivery
Science Daily - 9 May 2019 18:51
Many studies indicating that DNA nanostructures can enter cells more readily than simple DNA strands are flawed, according to new research.
An electric tongue can handle more spicy foods than you can
Science Daily - 9 May 2019 18:51
Spicy food is huge business, and now researchers have found that an electronic tongue, or e-tongue, is more effective and accurate in taste-testing fiery foods than sensitive human taste buds.
Does sunscreen compromise vitamin D levels? Maybe not
Science Daily - 9 May 2019 17:54
Sunscreen can reduce the sun's adverse effects, but there are concerns that it might inhibit the body's production of vitamin D. In a new study, however, investigators recorded an increase of vitamin D in participants du...
The heart 'talks' to fat cells
Science Daily - 9 May 2019 17:54
Like sending a letter through the mail or a text over a cellular network, the heart can generate messages that travel long distances through the body. Those messages ultimately reach fat cells, new research shows. The fi...
Painting a fuller picture of how antibiotics kill
Science Daily - 9 May 2019 17:22
Researchers have used machine-learning algorithms to discover a secondary mechanism that helps some antibiotics kill bacteria. This mechanism involves disrupting bacterial metabolism of nucleotides that the cells need to...
