A 14,000-year paleoecological reconstruction of the sub-Antarctic islands has found that seabird establishment occurred during a period of regional cooling 5,000 years ago. Their populations, in turn, shifted the Falkland Islands ecosystems through the deposit of high concentrations of guano that helped nourish tussac, produce peat and increase the incidence of fire.

Researchers develop a new method to isolate specific cells, and in the process find a more robust fluorescent protein.

Research has found permafrost to be mostly absent throughout the shallow seafloor along a coastal field site in northeastern Alaska. That means carbon can be released from coastline sources much more easily than previously thought.

Stress is present everywhere, even bacteria and plant cells have to cope with it. They express various specific stress proteins, but how exactly this line of defense works is often not clear. A group of scientists has now discovered a protective mechanism in cyanobacteria as well as in chloroplasts of plant cells.

Recent successes of several FDA-approved therapeutic nucleic acids, together with the rapid preclinical progression of nucleic acid nanoparticles (NANPs), have made it apparent that immunological effects of NANPs must be carefully assessed to permit their successful clinical translation. Based on extensive studies, a standardized protocol allowing for the assessment of NANPs' pro-inflammatory...

Using two mode-locked femtosecond lasers and a single photon counting detector, scientists have recorded broad spectra with close to one hundred thousand colors in almost complete darkness.

The COVID-19 pandemic has escalated into a 'syndemic' for people with chronic illnesses, a new study analyzing data from low and middle-income countries shows.

Serotonin can act as a growth factor for the stem cells in the fetal human brain that determine brain size.

Sponges are filter feeders that live on particulate matter -- but they can also ingest microscopic fragments of plastics and other pollutants of anthropogenic origin. They can therefore serve as useful bioindicators of the health of marine ecosystems.

A team of leading environmental experts have warned that the current war on plastic is detracting from the bigger threats to the environment.

Using an RNA molecule complex, researchers can prevent retention of cancer stem cell in their tumor supporting niche.

The critically endangered vaquita has survived in low numbers in its native Gulf of California for hundreds of thousands of years, a new genetic analysis has found. The study found little sign of inbreeding or other risks often associated with small populations.

What about the kidneys make them a hotspot for COVID-19's cytokine storm? A research team says it's the presence of a protein found on specialized renal transport cells.

Based on a quantum cascade laser (QCL) emitting mid-infrared light, the researchers developed a basic optical neuron system operating 10,000× faster than biological neurons.

There is much debate surrounding the age of the Clovis -- a prehistoric culture named for stone tools found near Clovis, New Mexico in the early 1930s -- who once occupied North America during the end of the last Ice Age. New testing of bones and artifacts show that Clovis tools were made only during a brief, 300-year period from 13,050 to 12,750 years ago.

A biologist conducted experiments with North American freshwater fish called least killifish. She found that fish exposed to estrogen in concentrations of 5 nanograms per liter in controlled lab conditions had fewer males and produced fewer offspring. Scientists have found estrogen at as much as 16 times that concentration in streams adjacent to sewage treatment plants.

Biologists have used the model organism Caenorhabditis elegans to identify molecular mechanisms that produce DNA damage in sperm and contribute to male infertility following exposure to heat.

An international research team has developed a methodology to help disaster preparedness officials in large cities make contingency plans on a region-wide basis to make sure that emergency responders can get patients to the hospital facilities that are likeliest to remain in commission after a quake.

The prescription of potentially inappropriate medications to older adults is linked to increased hospitalizations, and it costs patients, on average, more than $450 per year, according to a new study.

POSTECH Professor Byoungwoo Kang's research team uncovers a new Li-ion battery electrode material that can achieve high-energy density and high power capability per volume without reducing particle size.

Cool research story with connections to atomic clocks, Einstein and quantum mechanics. The research shows the 'spooky' interference that can impact even the most sophisticated clocks.

A new study has found that anxiety and stress directly linked to COVID-19 could be causing a number of body image issues. The research, which involved 506 UK adults, found that worries linked to COVID-19 were associated with body dissatisfaction and a desire for thinness in women, and associated with body fat dissatisfaction and a desire for muscularity in men.

New research details how a cell-free test rapidly detects COVID-19 neutralizing antibodies and could aid in vaccine testing and drug discovery efforts.

Hospitalized COVID-19 patients who were taking a daily low-dose aspirin to protect against cardiovascular disease had a significantly lower risk of complications and death compared to those who were not taking aspirin, according to a new study.
