Cells" replication of DNA is more "error-prone" in microgravity
On 22 May 2019, scientists from Queen's University boarded a modified Falcon 20 aircraft at Ottawa airport. Scheduled was a 'vomit comet' flight, where the plane repeatedly climbs to 8km in a steep parabola, alternating with a descent in freefall. Du.....»»
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......»»
Trimetallic-based nanocarriers method shows promise for visualized idiopathic pulmonary fibrosis therapy
A research group from Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS) developed a novel method for idiopathic pulmonary fibrosis (IPF) therapy by transplanting mesenchymal stem cells (MSCs), w.....»»
Modified nano-sized cell particles found to boost cancer immunotherapy, reduce side effects
Immunotherapy is a type of cancer treatment that uses the body's own immune system to help fight cancer. This is by stimulating the immune response to recognize and attack cancer cells more effectively. The treatment involves using substances that bo.....»»
Week in review: Veeam Backup & Replication RCE could soon be exploited, Microsoft fixes 4 0-days
Here’s an overview of some of last week’s most interesting news, articles, interviews and videos: Veeam Backup & Replication RCE flaw may soon be leveraged by ransomware gangs (CVE-2024-40711) CVE-2024-40711, a critical vulnerability affecting Ve.....»»
Ethics of biobanking for conservation: Researchers adjust ethical assessment tool for the use of genome research banks
In the face of the global biodiversity crisis, more and more biobanks are being set up to safeguard and potentially restore genetic diversity. Preserved tissue or cells allow scientists and conservationists to overcome spatial and even temporal fragm.....»»
How bacteria actively use passive physics to make biofilms
When we think about bacteria, we may imagine single cells swimming in solution. However, similarly to humans, bacterial cells often socialize, using surfaces to coalesce into complex heterogeneous communities called biofilms. Within a group, bacteria.....»»
Scientific jargon, entrenched teaching methods and student roles stifle science engagement, study says
Just as Danish school kids get to test their hands at science in earnest they come face to face with entrenched teaching methods, coded language and a no-error culture. New research from the University of Copenhagen shows that students get locked int.....»»
Researchers aim to control gene expression by studying the memories of cells
Communication between cells is now believed to activate a memory mechanism that sustains gene expression, a finding based on the work of Dr. Gregory Reeves......»»
GM has long history of partnering with rivals including Hyundai
An alliance with Honda has lasted for more than two decades and resulted in production of hydrogen fuel cells and electric vehicles, but some other tie-ups quickly fizzled......»»

Beyond needles: Introducing a new, nature-based approach for delivering cargo into egg cells
A new approach for delivering miniature research tools into the interior of egg cells and embryos has been developed at the Marine Biological Laboratory (MBL), resolving a major bottleneck to using the gene-editing tool CRISPR-Cas9 in many research o.....»»
Microsoft performs operations with multiple error-corrected qubits
Microsoft boosts error correction on Quantinuum machine, partners with Atom Computing. Enlarge / Quantinuum's H2 "racetrack" quantum processor. (credit: Quantinuum) On Tuesday, Microsoft made a series of announcements re.....»»
Experimental nanomedicine delivers chemo drugs directly to tumors in mice
Researchers at the University of Chicago Medicine Comprehensive Cancer Center have developed a nanomedicine that increases the penetration and accumulation of chemotherapy drugs in tumor tissues and effectively kills cancer cells in mice......»»
Pausing biological clock could give boost to lab-produced blood stem cells
A decade ago, Raquel Espin Palazon discovered that inflammatory signaling pathways must switch on for embryos to produce blood stem cells. The latest work from her lab shows the potential value of keeping those same signals switched off after their i.....»»
Veeam Backup & Replication RCE flaw may soon be leveraged by ransomware gangs (CVE-2024-40711)
CVE-2024-40711, a critical vulnerability affecting Veeam Backup & Replication (VBR), could soon be exploited by attackers to steal enterprise data. Discovered and reported by Code WHite researcher Florian Hauser, the vulnerability can be leveraged fo.....»»
Silver nanoparticles and a new sensing method can fight back against antibiotic-resistant biofilms
From safeguarding our food supply to preventing hospital infections, the battle against antibiotic-resistant bacteria is a growing challenge. Some bacteria can form biofilms, thick aggregates of millions of individual cells surrounded by protective m.....»»
