Slowing metabolic rate can prevent detrimental effects of genetic mutations
Science Daily - 25 Jul 2019 23:09
In a new study, researchers slowed mutant fruit flies' metabolic rates by 50%, and the expected detrimental effects of many mutations never manifested. After experimentally testing fruit flies' many different genetic mut...
Trapping female mosquitoes helps curb chikungunya virus
Science Daily - 25 Jul 2019 23:09
The US Centers for Disease Control and Prevention (CDC) recently developed an Autocidal Gravid Ovitrap (AGP trap) that attracts and captures female mosquitoes looking for a site to lay eggs. Now, researchers report that ...
When a fix for one vision problem causes another
Science Daily - 25 Jul 2019 23:09
Aging diminishes the ability of the eyes ability to focus up close. Research found that monovision, which uses lenses with different power in each eye, can cause dramatic misperceptions of distance and 3D direction for m...
Five or more hours of smartphone usage per day may increase obesity
Science Daily - 25 Jul 2019 23:09
As smartphones continue to be an inherent part of life and grow as a primary source of entertainment -- particularly among young people -- it leads to a decrease in physical activity. University students who used their s...
Biologists and mathematicians team up to explore tissue folding
Science Daily - 25 Jul 2019 23:09
Scientists have now discovered a key feature of embryonic tissue that helps explain how this process is carried out so faithfully each time. In a study of fruit flies, they found that the reproducibility of tissue foldin...
Current guides for starting infants on solid food may lead to overfeeding
Science Daily - 25 Jul 2019 23:03
Starting 6-month-old infants on solid food in the amounts recommended by standard feeding guides may lead to overfeeding, according to a new study.
New method enables more extensive preclinical testing of heart drugs and therapies
Science Daily - 25 Jul 2019 22:53
A new biomimetic culture system mimics the environment of a living organ through continuous electrical stimulation and oxygenation, maintaining viability and functionality of heart slices for six days. Previous culture s...
Einstein's general relativity theory is questioned but still stands for now
Phys.org - 25 Jul 2019 22:00
More than 100 years after Albert Einstein published his iconic theory of general relativity, it is beginning to fray at the edges, said Andrea Ghez, UCLA professor of physics and astronomy. Now, in the most comprehensive...

Physics of life: Motor proteins and membrane dynamics
Science Daily - 25 Jul 2019 19:26
Motility is an essential property of many cell types, and is driven by molecular motors. Researchers have now discovered that the motor protein myosin VI contributes directly to the deformation of the cell membrane, as r...
How neuromuscular connections are maintained after nerve lesions
Science Daily - 25 Jul 2019 19:25
After nerve injury, the protein complex mTORC1 takes over an important function in skeletal muscle to maintain the neuromuscular junction, the synapse between the nerve and muscle fiber. Researchers have now shown that t...
How to trick electrons to see the hidden face of crystals
Science Daily - 25 Jul 2019 19:25
The 3D analysis of crystal structures requires a full 3D view of the crystals. Crystals as small as powder, with edges less than one micrometer, can only be analysed with electron radiation. With electron crystallography...
