Endangered vaquita remain genetically healthy even in low numbers

Science Daily - 23/10/2020
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.

Research team discovers molecular processes in kidney cells that attract and feed COVID-19

Science Daily - 23/10/2020
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.

Extreme events in quantum cascade lasers

Science Daily - 23/10/2020
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.

Clovis people: Narrow window of tool-making

Science Daily - 23/10/2020
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.

Fish exposed to even small amounts of estrogen produce fewer males

Science Daily - 23/10/2020
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.

Researchers reveal why heat stress damages sperm

Science Daily - 23/10/2020
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.

A new technique predicts how earthquakes would affect a city's hospitals

Science Daily - 23/10/2020
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.

34% of older adults in the US are prescribed potentially inappropriate drugs

Science Daily - 23/10/2020
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.

COVID-19 anxiety linked to body image issues

Science Daily - 23/10/2020
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.

Scientist develops new way to test for COVID-19 antibodies

Science Daily - 23/10/2020
New research details how a cell-free test rapidly detects COVID-19 neutralizing antibodies and could aid in vaccine testing and drug discovery efforts.

Aspirin use reduces risk of death in hospitalized COVID-19 patients

Science Daily - 23/10/2020
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.

Gut hormone blocks brain cell formation and is linked to Parkinson's dementia

Science Daily - 23/10/2020
A gut hormone, ghrelin, is a key regulator of new nerve cells in the adult brain, a research team has discovered. It could help pave the way for new drugs to treat dementia in patients with Parkinson's Disease.
