Scientists study the rugged surface of near-Earth asteroid Bennu
- ScienceDaily
- 20/10/8 23:06
As the days count down to NASA's OSIRIS-REx spacecraft's Touch-And-Go asteroid sample collection attempt, scientists have determined what the spacecraft can expect to return from the near-Earth asteroid Bennu's surface. Three papers discuss the color, reflectivity, age, composition, origin and distribution of materials that make up the asteroid's rough surface.
Scientists peer inside an asteroid
- ScienceDaily
- 20/10/8 23:06
New findings from NASA's OSIRIS-REx mission suggest that the interior of the asteroid Bennu could be weaker and less dense than its outer layers -- like a crème-filled chocolate egg flying though space.

New method can pinpoint cracks in metal long before they cause catastrophes
- ScienceDaily
- 20/10/8 20:21
When metallic components in airplanes, bridges and other structures crack, the results are often catastrophic. But researchers have found a way to reliably predict the vulnerabilities earlier than current tests. Researchers detail a new method for testing metals at a microscopic scale that allows them to rapidly inflict repetitive loads on materials while recording how ensuing damage evolves into...
Drug delivery systems to treat connective tissue disorders
- ScienceDaily
- 20/10/8 20:21
A research team has devised tiny cargo-carrying systems many times smaller than a human hair, made from molecules called peptides that help provide structure for cells and tissues. The team has reported advances in the nanoparticle design that allow them to control the shape of the nanoparticles to allow them to better bind to tissue in the body and stay in a particular location.
New class of highly effective inhibitors protects against neurodegeneration
- ScienceDaily
- 20/10/8 20:21
Neurobiologists have uncovered how a special receptor can lead to cell death. Their fundamental findings on neurodegenerative processes simultaneously led the researchers to a completely new principle for therapeutic agents. In their experiments on mouse models, they discovered a new class of highly effective inhibitors for protecting nerve cells. This novel class of drugs opens up perspectives to...

Vaporized metal in the air of an exoplanet
- ScienceDaily
- 20/10/8 20:21
Researchers studied the atmosphere of the ultra-hot exoplanet WASP-121b. In it, they found a number of gaseous metals. The results are a next step in the search for potentially habitable worlds.

A new study shows the promise of high-throughput DNA-sequencing technologies to improve prenatal diagnosis and pregnancy outcomes for women who have experienced an abnormal prenatal ultrasound.
Moles: Intersexual and genetically doped
- ScienceDaily
- 20/10/8 20:21
Female moles not only have ovarian, but also testicular tissue that produces male sex hormones - which lets them diverge from the categorization into two sexes. A team describes which genetic modifications contribute to this singular development.
There's a gene for detecting that fishy smell, olfactory GWAS shows
- ScienceDaily
- 20/10/8 20:21
Some people carry a mutation in a particular gene that makes the smell of fish less intense. The study, which is the largest genome-wide association study (GWAS) of olfactory genes in humans involving a sniff test and looked at over 9,000 people from Iceland, also shows that people vary in their ability to discern the smell of licorice and cinnamon.
New species of aquatic mice discovered, cousins of one of the world's rarest mammals
- ScienceDaily
- 20/10/8 20:21
Scientists have discovered two new species of 'stilt mice,' semi-aquatic African rodents with extra-long feet that they stand up on like a kangaroo. The mice wade in streams and dip their whiskers onto the water's surface to detect bugs to eat. The researchers also helped clarify these rodents' family tree, which includes a genus that's only ever been collected once, 93 years ago.
HIV up close: Unprecedented view of virus reveals essential steps for causing AIDS
- ScienceDaily
- 20/10/8 20:21
Accomplishing a feat that had been a pipe dream for decades, scientists have recreated in a test tube the first steps of infection by HIV (human immunodeficiency virus), the virus that causes AIDS (acquired immunodeficiency syndrome). Doing so has provided up-close access to the virus -- which is otherwise obstructed from view deep within the cell -- and enabled identification of essential...
Olympic athletes should be mindful of their biological clocks
- ScienceDaily
- 20/10/8 20:20
Biological clocks have sizeable effects on the performance of elite athletes. This conclusion was drawn by chronobiologists after studying the times achieved by swimmers in four different Olympic Games. Shifting the clock to reach peak performance at the right time could make the difference between winning and losing.
Study finds fungal disease of snakes in 19 states, Puerto Rico
- ScienceDaily
- 20/10/8 20:20
Researchers surveyed for an infection caused by an emerging fungal pathogen that afflicts snakes. The research effort found infected snakes in 19 states and Puerto Rico, demonstrating that the fungus is more widely distributed than was previously known.

Researchers have made a breakthrough genetic discovery into the cause of a spectrum of severe neurological conditions.
One electrode fits all functional groups
- ScienceDaily
- 20/10/8 20:20
Researchers employed the gold electrode and attached the target molecules onto the electrode. Just like functional groups generate diverse electronic effects, one electrode fits all reactions as the single electrode can behave like multiple functional groups just with the switch of applied voltage.
Extinctions linked to new assemblages of species
- ScienceDaily
- 20/10/8 20:20
As the world undergoes profound environmental change, identifying and protecting 'novel' communities of species can help prevent extinctions within vulnerable ecosystems. Scientists outline a world first method to detect 'novel' communities of species across all ecosystems.
