A new study has revealed that these two ice giants are actually very similar shades of greenish blue

Neuropsychological effects of rapid-acting antidepressants may explain their clinical benefits

Science Daily - 11/01/2024
Rapid-acting antidepressants, including ketamine, scopolamine and psilocybin, have been found to have immediate and lasting positive effects on mood in patients with major depressive disorder but how these effects arise is unknown. New research has explored their neuropsychological effects and found that all three of these drugs can modulate affective biases associated with learning and memory.

Dry-cleaning fluid becomes a synthetic chemist's treasure

Science Daily - 11/01/2024
The widely used dry-cleaning and degreasing solvent perc can be converted to useful chemicals by a new clean, safe and inexpensive procedure. The discovery using on-demand UV activation may open the path to upcycling perc and thus contribute to a more sustainable society.

Natural compounds derived from soy and other plants reduce breast cancer recurrence and improve survival

Science Daily - 11/01/2024
Soy compounds called isoflavones are among the plant-derived compounds that may significantly reduce the risk of breast cancer recurrence or death, according to a new meta-analysis.

Genetics may influence the body's response to low oxygen

Science Daily - 11/01/2024
Researchers uncovered a fundamental mechanism that controls the body's response to limited oxygen and regulates blood vessel disease of the lung.

mRNA technology could be possible treatment for rare diseases

Science Daily - 11/01/2024
By exploiting the technology used in Covid-19 vaccines, a team of scientists has created an effective therapy for a rare disease, in a study in mice, demonstrating the technology's potential therapeutic use in people.

Feeling depressed linked to short-term increase in bodyweight

Science Daily - 11/01/2024
Increases in symptoms of depression are associated with a subsequent increase in bodyweight when measured one month later, new research has found. The study found that the increase was greatest among people with overweight or obesity, but found no link between generally having greater symptoms of depression and higher bodyweight.

Single-cell atlas of the placenta during term labor

Science Daily - 11/01/2024
An atlas revealing the activity of individual placental cells during childbirth offers insight on what happens at the maternal-fetal interface during term labor, according to a new study.

Newly identified genes for depression may lead to new treatments

Science Daily - 10/01/2024
More than 200 genes linked to depression have been newly identified in a worldwide study.

How 'pioneers' blaze the one trail that determines cell fate

Science Daily - 10/01/2024
A new CRISPR interference (CRISPRi) model explores how the pioneer transcription factor FOXA controls human endoderm differentiation during liver development, and how the pioneer transcription factor OCT4 influences the behavior of pluripotent stem cells. The unexpected findings could influence future organoid and cell reprogramming studies.

New research sheds light on an old fossil solving an evolutionary mystery

Science Daily - 10/01/2024
Picrodontids -- an extinct family of placental mammals that lived several million years after the extinction of the dinosaurs -- are not primates as previously believed.

Scientists discover potential nasal COVID-19 vaccine candidate that offers better and longer protection

Science Daily - 10/01/2024
Novel findings from a preclinical head-to-head comparison show that administering a COVID-19 vaccine as a nasal spray rather than a subcutaneous injection enhances the body's long-term immune memory, thereby increasing the vaccine's overall effectiveness. This research could pave the way for a COVID-19 vaccination strategy that depends on fewer boosters to achieve the same level of protection against SARS-CoV-2 viruses.

Traumatic stress associated with smaller brain region

Science Daily - 10/01/2024
Research reveals that adults with PTSD have a 2% smaller cerebellum than people without the disorder. The finding expands understanding of the cerebellum's role in the brain beyond balance and movement to include emotion and cognition and also suggests that targeting the cerebellum may improve current treatments for PTSD, such as deep brain stimulation.

Discovery of immense fortifications dating back 4,000 years in north-western Arabia

Science Daily - 10/01/2024
The North Arabian Desert oases were inhabited by sedentary populations in the 4th and 3rd millennia BCE. A fortification enclosing the Khaybar Oasis -- one of the longest known going back to this period -- was just revealed by a team of scientists. This new walled oasis is, along with that of Tayma, one of the two largest in Saudi Arabia.

Special brain cells react to unexpected situations

Science Daily - 10/01/2024
New research from the Netherlands Institute for Neuroscience shows that chandelier cells, a specific type of brain cell, become active during unexpected situations. 'Researchers have been wondering about the functionality of these cells for a long time'.

Scientists discover how ultraviolet light degrades coronavirus

Science Daily - 10/01/2024
New research has revealed how light can be used to destroy infectious coronavirus particles that contaminate surfaces. Scientists are interested in how environments, such as surgeries, can be thoroughly disinfected from viruses such as SARS-CoV-2 that caused the COVID-19 pandemic.

Exposure therapy addressing fear of spiders can also reduce fear of heights

Science Daily - 10/01/2024
Exposure therapy for a specific fear can also help reduce other fears. This is the conclusion reached by psychologists who studied 50 people with a fear of spiders and heights. Although they only treated the fear of spiders, the fear of heights was likewise reduced in the process.

Noninvasive technique reveals how cells' gene expression changes over time

Science Daily - 10/01/2024
A new method can track changes in live cell gene expression over extended periods of time. Based on Raman spectroscopy, the method doesn't harm cells and can be performed repeatedly.

Novel railway point switching technology, inspired by aircraft control systems

Science Daily - 10/01/2024
Researchers are working on a new cutting-edge railway switch (points) technology to improve upon the traditional design, which has been in use for over 200 years.
