Nutrient research reveals pathway for treating brain disorders

4:12
The team discovered that an essential nutrient called choline is transported into the brain, across the blood-brain barrier, by a protein transporter called FLVCR2. This is discovery will inform future design of drugs for diseases such as Alzheimer's and stroke, mimicking choline so they can be smuggled into the brain.

Archaea can be picky parasites

3:08
A parasite that not only feeds of its host, but also makes the host change its own metabolism and thus biology. Microbiologists have shown this for the very first time in a specific group of parasitic microbes, so-called DPANN archea. Their study shows that these archaea are very 'picky eaters', which might drive their hosts to change the menu.

EPA underestimates methane emissions from landfills, urban areas

3:08
The Environmental Protection Agency (EPA) is underestimating methane emissions from landfills, urban areas and U.S. states, according to a new study. The researchers combined 2019 satellite observations with an atmospheric transport model to generate a high-resolution map of methane emissions, which was then compared to EPA estimates from the same year. The researchers found: Methane emissions from landfills are 51% higher compared to EPA estimates Methane emissions from 95 urban areas are 39% …

Feathers, cognition and global consumerism in colonial Amazonia

3:08
Amazonia is the home of the largest variety of birds in the world. In such a unique environment, craft cultures have flourished by translating the beauty and creativity of environmental materials like feathers into stunning pieces of art. A new article examines artisanal featherwork within the context of early modern colonialism and globalization.

The big quantum chill: Scientists modify common lab refrigerator to cool faster with less energy

3:08
Scientists have dramatically reduced the time and energy required to chill materials to temperatures near absolute zero. Their prototype refrigerator could prove a boon for the burgeoning quantum industry, which widely uses ultracold materials.

Therapy to kill hypervirulent bacteria developed

2:36
A study has identified a therapy that can penetrate the slime that such infections use to protect themselves from antibiotics. Scientists showed that an antimicrobial peptide from cows has potential for treating incurable infections from the bacterium Klebsiella pneumoniae. The bacteria, commonly found in the intestines, is usually harmless. It becomes a health hazard when it enters other parts of the body and can cause pneumonia, urinary tract and wound infections. Those at highest risk includ…

Research breakthrough on birth defect affecting brain size

2:36
A team has identified a molecular cellular mechanism that is linked to microencephaly, a condition in which a baby's head is much smaller than expected.

Identifying risks of human flea infestations in plague-endemic areas of Madagascar

2:36
Researchers uncover why some homes in rural Madagascar where bubonic plague is endemic are infested with fleas. Based on their findings, they recommend ways to reduce the flea populations and their impact on human health.

Science has an AI problem: This group says they can fix it

2:36
A team of 19 prominent researchers has published guidelines for the responsible use of machine learning in science. They say it could avert a crisis that's smoldering in every field.

Key functions of therapeutically promising jumbo viruses

2:36
Viruses known as 'jumbo' phages are seen as a potential tool against deadly bacterial infections. But scientists must first decipher the extraordinary makeup of these mysterious viruses. Researchers have now uncovered a key piece of jumbo phage development that helps them counter bacteria.

Mystery behind huge opening in Antarctic sea ice solved

2:36
Researchers have discovered the missing piece of the puzzle behind a rare opening in the sea ice around Antarctica, which was nearly twice the size of Wales and occurred during the winters of 2016 and 2017. A study reveals a key process that had eluded scientists as to how the opening, called a polynya, was able to form and persist for several weeks.

Brain imaging study reveals connections critical to human consciousness

2:36
A new study involved high-resolution scans that enabled the researchers to visualize brain connections at submillimeter spatial resolution. Together, these pathways form a 'default ascending arousal network' that sustains wakefulness in the resting, conscious human brain.

Sleep resets brain connections -- but only for first few hours

2:36
During sleep, the brain weakens the new connections between neurons that had been forged while awake -- but only during the first half of a night's sleep, according to a new study.

Biomarkers in blood to predict liver cancer

2:36
Early detection has the potential to transform treatment and outcomes in cancer care, especially for cancers like liver cancer, which is typically diagnosed at a late stage with limited options for cure. A new study suggests that proteins detectable in the blood could improve predictions about risk of liver cancer years before typical diagnosis.

Why you can taste more ethanol in a cold pint of beer or warm glass of baijiu

2:36
We all have our own preferred drinking temperatures for different alcoholic beverages, with people commonly enjoying beer or white wine chilled, red wine near room temperature, or baijiu (Chinese whisky) or sake warmed. Now, researchers report that alcoholic beverages may taste more or less 'ethanol-like' at different temperatures, and this may be explained by how water and ethanol form either chain-like or pyramid-shaped clusters at the molecular level.
