Deducing the scale of tsunamis from the 'roundness' of deposited gravel

Sunday August 25th, 2019 11:59:34 AM
Scientists have found a link between the 'roundness' distribution of tsunami deposits and how far tsunamis reach inland. They sampled the 'roundness' of gravel from different tsunamis in Koyadori, Japan, and found a common, abrupt change in composition approximately 40% of the 'inundation distance' from the shoreline, regardless of tsunami magnitude. Estimates of ancient tsunami size from geological deposits may help inform effective disaster mitigation.

How diabetes can increase cancer risk: DNA damaged by high blood sugar

Sunday August 25th, 2019 11:59:32 AM
For years, scientists have been trying to solve a medical mystery: Why do people with diabetes have an increased risk of developing some forms of cancer? Today, researchers report a possible explanation for this double whammy. They found that DNA sustains more damage and gets fixed less often when blood sugar levels are high, thereby increasing cancer risk.

Light-matter interaction without interference

Saturday August 24th, 2019 12:49:35 AM
Quantum dots might constitute the foundation of quantum communication. They are an efficient interface between matter and light, with photons emitted by the quantum dots transporting information across large distances. However, structures form by default during the manufacture of quantum dots that interfere with communication. Researchers have now successfully eliminated these interferences.

Heart attack patients with mild cognitive impairment get fewer treatments

Friday August 23rd, 2019 10:27:09 PM
New research finds people with mild cognitive impairment don't always receive the same, established medical treatment that patients with normal cognitive functioning get when they have a heart attack.

Evolution designed by parasites

Friday August 23rd, 2019 10:27:02 PM
A new paper explores an overlooked aspect of the relationship between parasites and their hosts by systematically discussing the ways in which parasitic behavior manipulation may encourage the evolution of mechanisms in the host's nervous and endocrine systems.

A novel technology for genome-editing a broad range of mutations in live organisms

Friday August 23rd, 2019 10:27:00 PM
Researchers have developed a new tool -- dubbed SATI -- to edit the mouse genome, enabling the team to target a broad range of mutations and cell types. The new genome-editing technology could be expanded for use in a broad range of gene mutation conditions such as Huntington's disease and the rare premature aging syndrome, progeria.

Migrating mule deer don't need directions, study finds

Friday August 23rd, 2019 10:26:57 PM
Mule deer navigate in spring and fall mostly by using their knowledge of past migration routes and seasonal ranges, according to a new study.

Tech time not to blame for teens' mental health problems

Friday August 23rd, 2019 06:07:36 PM
A new study suggests that the time adolescents are spending on their phones and online is not that bad. The study tracked young adolescents on their smartphones to test whether more time spent using digital technology was linked to worse mental health outcomes.

Children of incarcerated parents have more substance abuse, anxiety

Friday August 23rd, 2019 06:07:34 PM
Children of incarcerated parents are six times more likely to develop a substance use disorder in adulthood and nearly twice as likely to have diagnosable anxiety compared to children whose parents were not incarcerated, according to new research.

Laser-produced uranium plasma evolves into more complex species

Friday August 23rd, 2019 06:07:32 PM
Mapping the evolution of complex uranium oxide species has practical applications from Mars exploration to nuclear proliferation detection.

Brain's astrocytes play starring role in long-term memory

Friday August 23rd, 2019 06:07:31 PM
Researchers have discovered that star-shaped cells called astrocytes help the brain establish long-lasting memories. The work could inform therapies for disorders in which long-term memory is impaired, such as traumatic brain injury or dementia.

How memories form and fade

Friday August 23rd, 2019 06:07:29 PM
Researchers have identified the neural processes that make some memories fade rapidly while other memories persist over time.

Can't get thinner than this: Synthesis of atomically flat boron sheets

Friday August 23rd, 2019 06:07:27 PM
Scientists have found a simple method for producing atomically thin layers of oxidized borophene, a promising 2D boron-based nanomaterial that could serve in a variety of fields.

Self-rolling sensors take heart cell readings in 3D

Friday August 23rd, 2019 06:07:23 PM
A new organ-on-an-electronic-chip platform uses self-rolling biosensor arrays to coil up and measure the electrophysiology of heart cells in 3D.

Analytical tool designs corkscrew-shaped nano-antennae

Friday August 23rd, 2019 06:07:19 PM
Researchers have derived analytically how corkscrew-shaped nano-antennas interact with light.

How microbes generate and use their energy to grow

Friday August 23rd, 2019 06:07:12 PM
Researchers have shed light on how bacteria and baker's yeast generate and use their energy to grow. Knowing about cells' energy use is essential for industrial biotech processes.

Successful egg harvest breaks new ground in saving the northern white rhinoceros

Friday August 23rd, 2019 06:07:06 PM
There are only two northern white rhinos left worldwide, both of them female. Saving this representative of megafauna from extinction seems impossible under these circumstances, yet an international consortium of scientists and conservationists just completed a procedure that could enable assisted reproduction techniques to do just that.

How gonorrhea develops resistance to antibiotics

Friday August 23rd, 2019 06:07:04 PM
As public health officials worry about the emergence of antibiotic-resistant gonorrhea, researchers are tracing how antibiotics bind to a gonococcal protein, information that can help lead to new antimicrobials.

New approaches to heal injured nerves

Friday August 23rd, 2019 06:06:51 PM
Researchers have deciphered new mechanisms that enable the regeneration of nerve fibers. This could open up new treatment approaches for the brain, optic nerve, and spinal cord injuries.

Bioprinting complex living tissue in just a few seconds

Friday August 23rd, 2019 01:48:32 PM
Researchers have developed an extremely fast optical method for sculpting complex shapes in stem-cell-laden hydrogels and then vascularizing the resulting tissue. Their groundbreaking technique stands to change the field of tissue engineering.
