Strong magnets put new twist on phonons
Phonons, quasiparticles in a crystal lattice that are usually hard to control by external fields, can be manipulated by a magnetic field — but it takes a very strong magnet.
Ancestors of legionella bacteria infected cells two billion years ago
Researchers have discovered that the ancestors of legionella bacteria infected eukaryotic cells as early as two billion years ago. It happened soon after eukaryotes began to feed on bacteria. These results are also relevant to the chicken-or-egg debate…
Key brain mechanisms for organizing memories in time
Using experiments and a deep machine learning data analysis approach, scientists uncovered the fundamental workings of the hippocampus region of the brain as it organizes memories into time sequences. The work could help future research into cognitive …
Starting antiretroviral therapy early essential to battling not one, but two killers
Medication against the nonhuman primate version of HIV given two weeks after infection helped keep tuberculosis in check.
Tracking seasonal and tidal effects on wastewater pollutants in the River Ganges
A new analysis of the River Ganges in West Bengal, India, highlights how wastewater flowing into the river impacts its water quality, and how that influence shifts with seasons and tides.
Study highlights worldwide disparities in treatment rates for major depressive disorder
A combined analysis of results from 149 earlier studies finds that treatment rates for major depressive disorder remain low worldwide, particularly for people living in low and lower-middle income countries.
Human microbiome research excludes developing world, study finds
New studies emerge daily on the effect of the human microbiome on human health: colon cancer, ulcers, and cognitive conditions such as Alzheimer’s disease have been associated with the communities of microbes that live in our bodies. However, global re…
Years of life lost during the pandemic significantly higher in deprived areas, study finds
The impact of the COVID-19 pandemic hit hardest in deprived areas of England and Wales, with excess years of life lost more than three times as high in the North West than the South West of England. The research also finds 11 times as many excess death…
Decoding KODA production to augment stress resistance in plants
KODA, an agrochemical produced in extremely low amounts, which helps plants cope with environmental stressors, has been the subject of extensive research. To bolster KODA production, researchers have developed a novel plant-based platform. Using biotec…
How embryo cells gain independence
It happens in the first hours after fertilization: The cells of the early embryo begin to independently produce proteins, the building blocks for cells and organs. Their own, uniquely composed genetic material serves as the blueprint. In vertebrates, t…
‘Blue Blob’ near Iceland could slow glacial melting
A region of cooling water in the North Atlantic Ocean near Iceland, nicknamed the ‘Blue Blob,’ has likely slowed the melting of the island’s glaciers since 2011 and may continue to stymie ice loss until about 2050, according to new research.
