Deadly virus"s pathway to infect cells identified
Rift Valley fever virus causes economically devastating outbreaks of hemorrhagic fever in livestock such as sheep, goats and cattle. These mosquito-borne outbreaks lead to infection in people working with dead or dying animals, sometimes causing hund.....»»
Study uncovers the secret of long-lived stem cells
Nothing lives forever, but compared to other cells in the body, hematopoietic stem cells (HSCs) are remarkably long-lived. HSCs are blood-forming cells—they give rise to rapidly dividing progenitor cells, which in turn generate hundreds of billions.....»»
Researchers suggest that mechanical pressure triggers a key event in HIV infection
It has been more than 40 years since the beginning of the HIV/AIDS epidemic and scientists still don't fully understand how HIV enters and replicates in human cells, which has hindered the development of treatments......»»
Chinese scientist who first published COVID sequence stages protest after being locked out of lab
The first scientist to publish a sequence of the COVID-19 virus in China staged a sit-in protest outside his lab after authorities locked him out of the facility—a sign of the Beijing's continuing pressure on scientists conducting research on the c.....»»
Cats suffer H5N1 brain infections, blindness, death after drinking raw milk

Scientists" research on RNA editing illuminates possible lifesaving treatments for genetic diseases
A team at Montana State University published research this month that shows how RNA, the close chemical cousin to DNA, can be edited using CRISPRs. The work reveals a new process in human cells that has potential for treating a wide variety of geneti.....»»
Cartilage healing discovery in animal models could lead to new human therapies
Researchers hope their discovery about the healing properties of fetal cartilage cells in mice will lay the groundwork for new treatments for human growth disorders and degenerative diseases......»»
Florida dolphin found with highly pathogenic avian flu: Report
The case of a Florida bottlenose dolphin found with highly pathogenic avian influenza virus, or HPAIV—a discovery made by University of Florida researchers in collaboration with multiple other agencies and one of the first reports of a constantly g.....»»
Study details a common bacterial defense against viral infection
One of the many secrets to bacteria's success is their ability to defend themselves from viruses, called phages, that infect bacteria and use their cellular machinery to make copies of themselves......»»
New structures offer insight into how a bacterial motor powers bacterial chemotaxis, a key infectious process
Bacteria existed for millennia before humans and have been infecting us from the beginning. Although we can treat infections through pharmaceuticals, bacteria continue to become resistant to treatment thanks to their rapid evolution. Bacterial infect.....»»
Study reveals protein"s key role in helping cilium transmit signals to the rest of the cell
The essential role played by a protein in the functioning of cells is revealed in new work from the laboratory of Université de Montréal medical professor Frédéric Charron, holder of the Canada Research Chair in Developmental Neurobiology......»»
Scientists regenerate neural pathways in mice with cells from rats
Two independent research teams have successfully regenerated mouse brain circuits in mice using neurons grown from rat stem cells. Both studies, published April 25 in the journal Cell, offer valuable insights into how brain tissue forms and present n.....»»
IRIS beamline at BESSY II gets a new nanospectroscopy end station
The IRIS infrared beamline at the BESSY II storage ring now offers a fourth option for characterizing materials, cells and even molecules on different length scales. The team has extended the IRIS beamline with an end station for nanospectroscopy and.....»»
Study says it"s likely a warmer world made deadly Dubai downpours heavier
Circumstantial evidence points to climate change as worsening the deadly deluge that just flooded Dubai and other parts of the Persian Gulf, but scientists didn't discover the definitive fingerprints of greenhouse gas-triggered warming they have seen.....»»
In south China, silkworm farmers reel from deadly floods
Hose in hand, 40-year-old Zhu Huangyi cleans a small concrete room once home to his silkworms, two thirds of which were lost in deadly floods hitting southern China this week......»»
Study suggests that cells possess a hidden communication system
Cells constantly navigate a dynamic environment, facing ever-changing conditions and challenges. But how do cells swiftly adapt to these environmental fluctuations?.....»»
A shade closer to more efficient organic photovoltaics
Transparent solar cells will transform the look of infrastructure by enabling many more surfaces to become solar panels. Now, materials called non-fullerene acceptors that can intrinsically generate charges when exposed to sunlight could make semitra.....»»
Unveiling the mysteries of cell division in embryos with timelapse photography
The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis are well-studied in the so-called somatic cells—the cells that have a specialized function, like skin and muscle cells—they remain elusive in the first cells of.....»»
Biomolecular condensates: Study reveals poor predictive power of established liquid-liquid phase separation assays
Cells buzz with millions of different biomolecules that diffuse chaotically through their substructures, yet they manage to ensure exquisite functional and spatial specificity......»»
Giant virus discovered in wastewater treatment plant infects deadly parasite
The single-celled organism Naegleria fowleri ranks among the deadliest human parasites. Researchers around Matthias Horn and Patrick Arthofer from the Center for Microbiology and Environmental Systems Science at the University of Vienna, in an intern.....»»
