Tracking down the tiniest of forces: How T cells detect invaders
What happens on a molecular level, when our immune system detects antigens? Scientists have found out, how T cells exert tiny forces on antigens. Bonds between T cells and antigen presenting cells break, and this behavior tells the T cell whether or.....»»
Physicists pioneer new quantum sensing platform
Quantum sensors detect the smallest of environmental changes—for example, an atom reacting to a magnetic field. As these sensors "read" the unique behaviors of subatomic particles, they also dramatically improve scientists' ability to measure and d.....»»
New discovery of a mechanism that controls cell division
Researchers at Umeå University, Sweden, have discovered that how a special protein complex called the Mediator moves along genes in DNA may have an impact on how cells divide. The discovery may be important for future research into the treatment of.....»»
Researchers develop "founding document" on synthetic cell development
Cells are the fundamental units of life, forming the variety of all living things on Earth as individual cells and multicellular organisms. To better understand how cells perform the essential functions of life, scientists have begun developing synth.....»»
Edgio ASM reduces risk from web application vulnerabilities
Edgio launched its Attack Surface Management (ASM) solution. ASM is designed to discover all web assets, provide full inventory of technologies, detect security exposures and manage exposure response across an organization from a centralized manageme.....»»
Nano-drugs hitching a ride on bacteria could help treat pancreatic cancer
Many pancreatic tumors are like malignant fortresses, surrounded by a dense matrix of collagen and other tissue that shields them from immune cells and immunotherapies that have been effective in treating other cancers. Employing bacteria to infiltra.....»»
For microscopic organisms, ocean currents act as "expressway" to deeper depths, study finds
Some of the ocean's tiniest organisms get swept into underwater currents that act as a conduit that shuttles them from the sunny surface to deeper, darker depths where they play a huge role in affecting the ocean's chemistry and ecosystem, according.....»»
Nanotubes, nanoparticles and antibodies detect tiny amounts of fentanyl
A research team at the University of Pittsburgh led by Alexander Star, a chemistry professor in the Kenneth P. Dietrich School of Arts and Sciences, has developed a fentanyl sensor that is six orders of magnitude more sensitive than any electrochemic.....»»
Bioreactor processes and cryotechnologies improve active ingredient tests using human cell cultures
Many new drug candidates end up failing because they cause serious side effects in clinical trials even though lab tests involving cell cultures have been successful. This is a common occurrence if the cells used come from animal tissue, for example......»»
Researchers detect toxic chemicals in aquatic organisms with new AI method
Swedish researchers at Chalmers University of Technology and the University of Gothenburg have developed an AI method that improves the identification of toxic chemicals—based solely on knowledge of the molecular structure......»»
Nord Security unveils NordStellar, a platform for advanced cyber threat detection and response
Nord Security introduces NordStellar, a next-generation threat exposure management platform. Created by developers of VPN solution NordVPN, the enterprise cyber threat exposure management platform helps businesses detect and respond to cyber threats,.....»»
Pennsylvania has two battling bills that could make tracking with AirTags unlawful
Pennsylvania state representatives have pushed forward a second piece of legislation that would penalize the unauthorized use of Bluetooth trackers, like AirTag, to track someone.Apple AirTagThere's no shortage of instances where someone discovered t.....»»
Unauthorized AirTag tracking set to become illegal in Pennsylvania
Technology comes with its pros and cons, and among modern Apple devices that’s been especially true with . Like other Bluetooth trackers, since their debut AirTags have been used by stalkers and other bad actors to track others without their consen.....»»
Cell contraction drives the initial shaping of human embryos, study finds
Human embryo compaction, an essential step in the first days of an embryo's development, is driven by the contractility of its cells. This is the finding of a team of scientists from CNRS, Institut Curie, Inserm, AP-HP and the Collège de France. Pub.....»»
Two giants in the satellite telecom industry join forces to counter Starlink
SES is buying Intelsat, the world's first commercial satellite operator, for $3.1 billion. Enlarge / The Intelsat 901 satellite is seen by a Northrop Grumman servicing vehicle in 2020. (credit: Northrop Grumman) Facing c.....»»
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.....»»
Apple Working to Fix iPhone Alarm Issues
If your iPhone’s alarm isn’t playing a sound properly, you aren’t alone. The issue is widespread enough that Apple is working on a fix for the issue. We’ve been tracking problems with the iPhone and iOS in April and one of the.....»»
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......»»
Tracking the dynamics of biomolecules with optofluidic antennas
In order to better understand fundamental processes in life science at the molecular level, the precise observation of single molecule dynamics is of utmost interest. However, current techniques based on fluorescence measurements in aqueous solutions.....»»
Inexpensive spring truffles or exquisite Piedmont truffles? New analytical method can detect food fraud
Some truffles are particularly expensive and therefore often the target of food fraud. For example, high-priced Piedmont truffles (Tuber magnatum) are often difficult to distinguish from the cheaper spring truffles (T. borchii) on the basis of their.....»»
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.....»»
