Researchers identify novel endocytic recycling mechanism with "kiss-and-run" membrane fusion
Endocytosis and recycling control the uptake and retrieval of various materials in eukaryotic cells. Mammalian cells have developed several recycling routes, including the relatively extensively studied "fast" and "slow" tubulovesicular recycling pat.....»»
Recharging mitochondria—nanoflowers offer a new way to simulate energy production to improve aging ailments
When we need to recharge, we might take a vacation or relax at the spa. But what if we could recharge at the cellular level, fighting against aging and disease with the microscopic building blocks that make up the human body?.....»»
Double-edged STING: A new pathway involved in aging
A protein called STING, previously shown to control a pathway that contributes to antiviral signaling, also plays an important role in cellular stress clearance and cell survival, according to a new paper published in Molecular Cell......»»
First iPhone 16 pre-orders arrive as lines form at Apple Stores around the world
As the clock turns to September 20 around the world, the iPhone 16 and iPhone 16 Pro launch is in full swing. The first pre-orders have started arriving to lucky buyers, while lines are starting to form at Apple Stores. As we highlighted earlier,.....»»
First-of-its kind tool allows scientists to manipulate cells without touching them
When studying the spread of cancer or the behavior of a virus like the one that causes COVID-19, the irony is that working with these harmful pathogens requires gentleness. Especially in the case of COVID, the particles do not survive well when makin.....»»
Redwood Materials signs deal to recycle BMW’s EV batteries in the US
The automaker will use recycled materials from Redwood in its American-made EVs. Enlarge / BMW is moving to cylindrical cells for its sixth-generation EV powertrain, which debuts in the Neue Klasse. And now it has a recycling par.....»»
Silencing in action: How cells "repress" genomic remnants of ancient viruses
Researchers have identified key cellular control sites that regulate gene expression and prevent the activation of "cryptic" genomic regions, including ancient viral sequences......»»
Reinventing the clock: NASA"s new tech for space timekeeping
Here on Earth, it might not matter if your wristwatch runs a few seconds slow. But crucial spacecraft functions need accuracy down to one billionth of a second or less. Navigating with GPS, for example, relies on precise timing signals from satellite.....»»
What Is Sickle Cell Disease?
You have around 35 trillion red blood cells moving around your body at all times. Typically they are rounded and flexible. What happens when they aren’t?.....»»
The Next President Should End NASA’s Space Launch System Rocket
Rather than building an obsolescent, obscenely-over-budget jumbo rocket, NASA should turn to building truly innovative space technologies and plan a realistic lunar landing program.....»»
RSV Can Be a Killer. New Tools Are Identifying the Most At-Risk Kids
RSV infects almost every child before they turn 2, and kills more than 100,000 infants worldwide each year. Machine learning and statistical models are identifying those most at risk......»»
Q&A: Authors discuss addressing the crisis of species loss
No oncologist would wait for a patient's cancer to spread before treating it. Similarly, waiting to detect the potential loss of a species across all its known habitats means interventions are often too late to turn the tide of extinction, according.....»»
Nuclear theorists turn to supercomputers to map out matter"s building blocks in 3D
Deep inside what we perceive as solid matter, the landscape is anything but stationary. The interior of the building blocks of the atom's nucleus—particles called hadrons that a high school student would recognize as protons and neutrons—are made.....»»
Computational tool can pinpoint causal relationships from complex biological data
Researchers have developed a tool that provides new insights into cause-and-effect relationships between cells and how these change over time......»»
Do bacteria age?
Any organism that lives, grows and reproduces must also age. People often think of aging in the physical sense—gray hair, slowed movements and wrinkles—but aging fundamentally occurs on a molecular level, inside of cells......»»
Scientists decipher the energy patterns in our cells
Our cells harness energy for essential functions such as division, wound healing, and our immune response to diseases including cancer. But until now, the mechanics of how that energy affects cell behavior—and how this relates to health outcomes—.....»»
Study sheds light on trade-off between noise and power in nanoscale heat engines
Thanks to nanoscale devices as small as human cells, researchers can create groundbreaking material properties, leading to smaller, faster, and more energy-efficient electronics. However, to fully unlock the potential of nanotechnology, addressing no.....»»
Optogenetic control reveals collective cell behavior
New research led by the Institute for Bioengineering of Catalonia (IBEC) has studied the migratory movement of groups of cells using light control. The results show that there is no leader cell that directs the collective movement, as previously thou.....»»
Researchers develop new method for delivering RNA and drugs into cells
Researchers at the University of Toronto and its hospital partners have developed a method for co-delivering therapeutic RNA and potent drugs directly into cells, potentially leading to a more effective treatment of diseases......»»
