A team led by researchers at Baylor College of Medicine and the Czech Academy of Sciences has uncovered a new piece of the puzzle of how gene expression is orchestrated. Published in the journal Science, the findings reveal a novel mechanism that coordinates the assembly of components inside cells that control gene expression. The mechanism not only is essential for normal cell function, but also has been implicated in cancer, neurodegeneration and HIV infection, and could suggest new ways to treat these conditions.

From 50,000 years to 6,000 years ago, many of the world's largest animals, including such iconic grassland grazers as the woolly mammoth, giant bison, and ancient horses, went extinct. The loss of these grazing species triggered a dramatic increase in fire activity in the world's grasslands, according to a new Yale-led study published Nov. 26 in the journal Science.

A team of researchers, including scientists from the National Superconducting Cyclotron Laboratory (NSCL) and the Facility for Rare Isotope Beams (FRIB) at Michigan State University (MSU), have solved the case of zirconium-80's missing mass.

Partnerships between organizations that support the implementation of the United Nations Sustainable Development Goals (SDGs) may perpetuate inequalities in resources between high and low-income countries according to new research. The findings are published in Scientific Reports.

Researchers have developed a jelly-like material that can withstand the equivalent of an elephant standing on it, and completely recover to its original shape, even though it's 80% water.

Seven Earth-sized planets orbit the star TRAPPIST-1 in near-perfect harmony, and U.S. and European researchers have used that harmony to determine how much physical abuse the planets could have withstood in their infancy.

A new multidisciplinary study by an international team reports the discovery of an ivory pendant decorated with a pattern of at least 50 punctures, creating an irregular looping curve. The direct radiocarbon date of the ornament yields an age of 41,500 years. This result indicates that the Stajnia Cave jewelry is the oldest punctate ornament known to date in Eurasia, predating other instances of this type of decoration activity by 2,000 years. This finding broadens our current knowledge on the timing... Читать дальше...

Scientists have discovered a new route to produce complex antibiotics exploiting gene editing to re-program pathways to future medicines urgently required to combat antimicrobial resistance, treat neglected diseases and tackle future pandemics.

Researchers have imaged a major component in conjugation—the process bacteria use to share DNA with each other.

A small team of researchers at the University of London has attempted to measure the factors that influence the amount of pleasure a person receives from hugging another person. In their paper published in the journal Acta Psychologica, the group describes two separate experiments they conducted to learn more about the experience of hugging, at least in the U.K.

An international research team have discovered a specific type of gut bacteria in bees that can improve memory.

Scientists have developed new materials for next-generation electronics so tiny that they are not only indistinguishable when closely packed, but they also don't reflect enough light to show fine details, such as colors, with even the most powerful optical microscopes. Under an optical microscope, carbon nanotubes, for example, look grayish. The inability to distinguish fine details and differences between individual pieces of nanomaterials makes it hard for scientists to study their unique properties... Читать дальше...

Data from ESA's Gaia mission is re-writing the history of our galaxy, the Milky Way. What had traditionally been thought of as satellite galaxies to the Milky Way are now revealed to be mostly newcomers to our galactic environment.

Mothers: they bring you into this world, shower you with care, and help you build up a mind map of local foraging sites while you're still a flightless pup latched to their nipples.

Russia on Thursday successfully placed into orbit a military satellite believed to be part of the Kremlin's early warning anti-missile system.

China's CO2 emissions fell in the third quarter for the first time since the country reopened from COVID-19 lockdowns, research published Thursday showed, in what experts said could mark a carbon "turning point" for the country.

Hanging halfway up an ancient oak tree, peering into a small, dark hole in its enormous trunk abuzz with bees, Filipe Salbany can barely contain himself.

Archaeologists have unearthed the first Roman mosaic of its kind in the UK. Today (Thursday 25th November 2021), a rare Roman mosaic and surrounding villa complex have been protected as a Scheduled Monument by DCMS on the advice of Historic England. The decision follows archaeological work undertaken by a team from University of Leicester Archaeological Services (ULAS), working in partnership with Historic England and in liaison with Rutland County Council.
