The ability to distinguish between left-and right-handed molecules using mass spectrometry could streamline a laborious part of drug discovery.
Immunotherapy has rapidly advanced the field of medicine and has saved countless lives. The approach is much different than using an external chemical, such as in the case of chemotherapy. Immunotherapy leverages the body’s own immune system to recognize and attack foreign pathogens, specifically cancer. While there are many versions of immunotherapy, one rising star among them is known as Chimeric Antigen Receptor (CAR) T cell therapy. This therapy (usually) takes a patient’s own cells in the blood to generate engineered immune or T cells to fight the tumor. T cells are a critical immune cell population responsible for killing or lysing infected cells. In the case of CAR T cell therapy, the T cells from the patient are engineered to recognize receptors on the tumor. The CAR T-cells are then triggered to release different proteins and lyse the tumor cells. This type of therapy has revolutionized the way we treat patients with hematopoietic malignancies or blood cancers.
Jenniskens’ collaborators at the Museum für Naturkunde officially announced that the first examinations of one of these pieces with an electron beam microprobe prove the typical mineralogy and chemical composition of an achondrite of the aubrite type.
The official classification now aligns with what many suspected from merely looking at the images of the strange meteorites that fell near Berlin on January 21, 2024. They belong to a rare group called “aubrites.”
“They were devilishly difficult to find because, from a distance, they look like other rocks on Earth,” said SETI Institute meteor astronomer Dr. Peter Jenniskens. “Close up, not so much.”
A collaborative research team has fabricated a soccer ball-shaped construction using edge-to-edge assembly of 2D semiconductor materials. The research has been featured on the cover of the online edition of the Angewandte Chemie International Edition journal.
The research team, led by Professor In Su Lee and Ph.D. candidate Sun Woo Jang from the Department of Chemistry at Pohang University of Science and Technology (POSTECH), along with Professor Kwangjin An from the Department of Energy and Chemical Engineering at Ulsan National Institute of Science and Technology (UNIST), successfully controlled the interaction between the edges of 2D-silica nanosheets (2D-SiNS) to create a soccer ball-like structure.
The planar structure of 2D nanosheets exhibit unique mechanical and optical properties, making them versatile in semiconductor devices, catalysts, sensors, and many other sectors. The strong attraction of intermolecular forces (van der Waals) between sheets typically results in a structure where faces are in direct contact, compromising mechanical stability for catalytic functionality.
In the XXI century, the world of orbital launchers has started a revolution, a fundamental change of paradigm: the replacement of expendable rockets with reusable ones is well underway. This presentation summarizes the situation at the beginning of year 2024.
A short bio.
Alberto Cavallo is an Electrical Engineer, graduated at the Politecnico di Torino in 1985. He began his activity with designing electric systems in Fiat Engineering, the engineering and construction company of the FIAT Group, moving soon to control and automation systems in the same company. He was involved in all business areas of the company, which included revamping and new projects of car factories for the FIAT Group as well as large infrastructures, power and cogeneration plants for external clients. Among the projects of that time were the new FIAT factories in Melfi and Pratola Serra, the high speed railways Torino-Milano and Bologna-Firenze, the district heating system of Torino Sud, combined cycle power plants for several hundred megawatts in Italy and in Brazil. Since Fiat Engineering was transferred from the FIAT Group to a new EPC group and then merged with a large EPC company in Milan, he has been involved in large oil and gas and petrochemical projects all over the world. Besides his professional activity, he has always taken part in several cultural activities. He was a member of the Associations of Alumni of the Liceo Classico Vittorio Alfieri of Turin, active in promoting humanistic culture as well as its connection to the technical and scientific area. He manages his own website www.eurinome.it (in Italian only) about philosophy, science and politics/geopolitics. Due to this he got in contact with Adriano Autino and his TDF, then becoming one of the founding members of Space Renaissance International. Besides several papers in his professional area he has written several articles for his own site, for TDF and SRI, coauthoring the book “Three Theses for the Space Renaissance” with Adriano Autino and Patrick Q. Collins. He is currently member of the Board of SRI.
We are in the middle of a data-driven science boom. Huge, complex data sets, often with large numbers of individually measured and annotated ‘features’, are fodder for voracious artificial intelligence (AI) and machine-learning systems, with details of new applications being published almost daily.
But publication in itself is not synonymous with factuality. Just because a paper, method or data set is published does not mean that it is correct and free from mistakes. Without checking for accuracy and validity before using these resources, scientists will surely encounter errors. In fact, they already have.
In the past few months, members of our bioinformatics and systems-biology laboratory have reviewed state-of-the-art machine-learning methods for predicting the metabolic pathways that metabolites belong to, on the basis of the molecules’ chemical structures1. We wanted to find, implement and potentially improve the best methods for identifying how metabolic pathways are perturbed under different conditions: for instance, in diseased versus normal tissues.
With the support of electrical transport and magnetic measurement systems of Steady High Magnetic Field Facility (SHMFF), a research team from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), discovered a new superconducting material called (InSe2)xNbSe2, which possesses a unique lattice structure. The superconducting transition temperature of this material reaches 11.6 K, making it the transition metal sulfide superconductor with the highest transition temperature under ambient pressure.
The results were published in Journal of the American Chemical Society.
TMD materials have received lots of attention due to their numerous applications in the fields of catalysis, energy storage, and integrated circuits. However, the relatively low superconducting transition temperatures of TMD superconductors have limited their potential use.
In the future, soft robots will be able to perform tasks that cannot be done by conventional robots. These soft robots could be used in terrain that is difficult to access and in environments where they are exposed to chemicals or radiation that would harm electronically controlled robots made of metal. This requires such soft robots to be controllable without any electronics, which is still a challenge in development.
A research team at the University of Freiburg has now developed 3D-printed pneumatic logic modules that control the movements of soft robots using air pressure alone. These modules enable logical switching of the air flow and can thus imitate electrical control.
The modules make it possible for the first time to produce flexible and electronics-free soft robots entirely in a 3D printer using conventional filament printing material.
Researchers have developed an ingenious air-powered soft valve circuit system devoid of electronics, showcasing its utility in a drink dispenser and its durability as a car drives over it.
The 3D-printed valve system showcases how well soft devices without electronics can work, even when facing challenges that could turn off regular robots.
According to reseachers at the University of Freiburg, its integration into everyday applications heralds a new era in robust and adaptable robotics. Soft circuit devices, which are flexible and don’t use metal, can handle damage much better than those with delicate electronics. They can survive being crushed or exposed to harsh chemicals without breaking.
I believe that the nanotransfection using internal biocomputing will change psychiatric problems because it will physically repair problems with biocomputing rather chemical based computers. Also this could heal the software components aswell of the mind aswell.
Millions of Americans experience symptoms of a mental health condition each year, and the number of people seeking care is trending upward. While a mental health diagnosis may impact an individual’s daily life, it can also have a ripple effect across families, communities and even economies.
Here’s a closer look at the current state of mental health, including how many people experience mental health conditions and which populations are most at risk.
