'Clock' created to predict immunological health and chronic diseases of aging

Science Daily - 12/07/2021
Researchers have created an inflammatory clock of aging (iAge) which measures inflammatory load and predicts multi-morbidity, frailty, immune health, cardiovascular aging and is also associated with exceptional longevity in centenarians.

Coastal ecosystems worldwide: Billion-dollar carbon reservoirs

Science Daily - 12/07/2021
Australia's coastal ecosystems alone save the rest of the world costs of around 23 billion US dollar a year by absorbing CO2 from the atmosphere. Coastal ecosystems such as seagrass meadows, salt marshes and mangrove forests make an important contribution to mitigating climate change.

Haziness of exoplanet atmospheres depends on properties of aerosol particles

Science Daily - 12/07/2021
Many exoplanets have opaque atmospheres, obscured by clouds or hazes that make it hard for astronomers to characterize their chemical compositions. A new study shows that haze particles produced under different conditions have a wide range of properties that can determine how clear or hazy a planet's atmosphere is likely to be.

A fermented-food diet increases microbiome diversity and lowers inflammation, study finds

Science Daily - 12/07/2021
A diet rich in fermented foods enhances the diversity of gut microbes and decreases molecular signs of inflammation, according to researchers.

Technology that restores the sense of touch in nerves damaged as a result of injury

Science Daily - 12/07/2021
Researchers have developed a sensor that can be implanted anywhere in the body -- for example, under the tip of a severed finger. The sensor connects to another nerve that functions properly and restores tactile sensation to the injured nerve. The development is biocompatible and does not require electricity, wires, or batteries.

Ecologists develop a novel forensic tool for detecting laundering of critically endangered cockatoos

Science Daily - 12/07/2021
Ecologists have applied stable isotope techniques to determine whether birds in the pet trade are captive or wild-caught, a key piece of evidence required in many cases to determine whether a trade is legal or not. They have applied this technique to the yellow-crested cockatoo, a critically endangered species from Indonesia/Timor-Leste with a global population of fewer than 2,500.

Let crop residues rot in the field -- it's a climate win

Science Daily - 12/07/2021
Plant material that lies to rot in soil isn't just valuable as compost. In fact, agricultural crop residue plays a crucial role in sequestering carbon, which is vital for reducing global CO2 emissions.

Human environmental genome recovered in the absence of skeletal remains

Science Daily - 12/07/2021
Ancient sediments from caves have already proven to preserve DNA for thousands of years. The amount of recovered sequences from environmental sediments, however, is generally low, which complicates analyses. A study has now successfully retrieved three mammalian environmental genomes from a single soil sample of 25,000 years BP obtained from the cave of Satsurblia in the Caucasus (Georgia).

How the universe is reflected near black holes

Science Daily - 12/07/2021
In the vicinity of black holes, space is so warped that even light rays may curve around them several times. This phenomenon may enable us to see multiple versions of the same thing. While this has been known for decades, only now do we have an exact, mathematical expression.

Mathematicians develop ground-breaking modeling toolkit to predict local COVID-19 impact

Science Daily - 12/07/2021
Mathematicians have created a new modeling toolkit which predicts the impact of COVID-19 at a local level with unprecedented accuracy.

Rise in Southeast Asia forest clearance increasing greenhouse gases

Science Daily - 12/07/2021
Forest clearance in Southeast Asia is accelerating, leading to unprecedented increases in carbon emissions, according to new research. The findings show that forests are being cut down at increasingly higher altitudes and on steeper slopes in order to make way for agricultural intensification.

Preferred life expectancy and its association with hypothetical adverse life scenarios

Science Daily - 12/07/2021
A new study sheds light on how the specter of dementia and chronic pain reduce people's desire to live into older ages. Among Norwegians 60 years of age and older the desire to live into advanced ages was significantly reduced by hypothetical adverse life scenarios with the strongest effect caused by dementia and chronic pain.

Sea-level rise may worsen existing San Francisco Bay Area inequities

Science Daily - 12/07/2021
Researchers examined the number of households unable to pay for damages from coastal flooding to reveal how sea-level rise could threaten the fabric of Bay Area communities over the next 40 years.

People given 'friendly' bacteria in nose drops protected against meningitis, study suggests

Science Daily - 12/07/2021
A recent trial has shown that nose drops of modified 'friendly' bacteria may protect against meningitis.

Sensing 'junk' RNA after chemotherapy enhances blood regeneration

Science Daily - 12/07/2021
Scientists reveal that during hematopoietic regeneration, RNA expressed from a part of the genome considered 'junk DNA' is used by hematopoietic stem cells to get activated and proliferate. The study shows that these so-called transposable elements make RNA after chemotherapy and activate an immune receptor which induces inflammatory signals enhancing hematopoietic stem cell cycling and thus participating in the regeneration of the hematopoietic system.

Training helps teachers anticipate how students with learning disabilities might solve problems

Science Daily - 12/07/2021
Researchers found that a four-week training course made a substantial difference in helping special education teachers anticipate different ways students with learning disabilities might solve math problems.

Every spot of green space counts

Science Daily - 12/07/2021
An international study of parks and gardens finds even the humble roadside verge plays an important role in the environment and for our health.

Reviewing pressure effects on iron-based high-temperature superconductors

Science Daily - 12/07/2021
A new study reviews progress on high-pressure studies on properties of iron-based superconductor (ISBC) families, and examines the use of pressure as a versatile method for exploring new materials.

Remarkable new insights into the pathology of Usher syndrome

Science Daily - 12/07/2021
Human Usher syndrome is the most common form of hereditary deaf-blindness. Researchers have now identified a novel pathomechanism leading to Usher syndrome. They have discovered that the Usher syndrome type 1G protein SANS plays a crucial role in regulating splicing process. Furthermore, they have been able to demonstrate that defects in the SANS protein can lead to errors in the splicing of genes related to the Usher syndrome, which may provoke the disease.

Giving a 'tandem' boost to solar-powered water splitting

Science Daily - 12/07/2021
Scientists combine two promising photocatalysts to obtain higher solar-to-hydrogen conversion efficiency and durability in a water splitting cell.
