Epic of a molecular ion: With eyes of electrons

Epic of a molecular ion: With eyes of electrons
2024-01-10
Ions are everywhere, from our daily surroundings to the cosmic expanse. As common table salt (NaCl) dissolves into sodium (Na+) and chloride (Cl-) ions in water, it imparts a salty taste. Once absorbed by the body, these ions regulate nerve impulses and muscle movements. In the sun, plasma—a gathering of ions in the gaseous state—undergoes nuclear fusion reactions, transmitting light and energy to Earth. One of the most noteworthy usage ions in everyday life is found in lithium-ion batteries, ...

Scientists find “key” to potential breast cancer prevention, treatment

Scientists find “key” to potential breast cancer prevention, treatment
2024-01-10
CHAPEL HILL, N.C. – Every time a cancer cell divides, it sustains damage to its own DNA molecules. Researchers, including Gaorav Gupta, MD, PhD, associate professor in the Department of Radiation Oncology at the UNC School of Medicine, have long wondered how cancers are able to evade detection by the body’s own defenses, despite the immune system being on constant watch for cells displaying DNA damage. New findings by Gupta’s lab, which were published in Nature, shows how the cGAS-STING pathway – a pathway inside cells essential for activating the inflammatory immune response – is unleashed to prevent cancer formation by detecting DNA damage within ...

How ‘pioneers’ blaze the one trail that determines cell fate

How ‘pioneers’ blaze the one trail that determines cell fate
2024-01-10
One of the important breakthroughs that made it possible to program or reprogram cell fate more efficiently and with higher fidelity in a dish was discovering how to make use of a small set of molecular cowboys called pioneer transcription factors (TFs). Every cell in our bodies has more than 200 transcription factors expressed inside, riding along the DNA helix instructing specific genes to activate and deactivate. During the early stages of fetal development, a small subset of “pioneer” TFs act inside ...

Observing macroscopic quantum effects in the dark

Observing macroscopic quantum effects in the dark
2024-01-10
The boundary between everyday reality and the quantum world remains unclear. The more massive an object, the more localized it becomes when being made quantum through cooling down its motion to the absolute zero. Researchers, led by Oriol Romero-Isart from the Institute for Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences (ÖAW) and the Department of Theoretical Physics at the University of Innsbruck, propose an experiment in which an optically levitated nanoparticle, cooled to its ground state, evolves in a non-optical (“dark”) potential created by electrostatic or magnetic forces. This evolution in the dark potential ...

AI discovers that not every fingerprint is unique

AI discovers that not every fingerprint is unique
2024-01-10
Columbia engineers have built a new AI that shatters a long-held belief in forensics–that fingerprints from different fingers of the same person are unique. It turns out they are similar, only we’ve been comparing fingerprints the wrong way! New York, NY—January 12, 2024—From “Law and Order” to “CSI,” not to mention real life, investigators have used fingerprints as the gold standard for linking criminals to a crime. But if a perpetrator leaves prints from different fingers in two different crime scenes, these scenes are very difficult to link, and the trace can go ...

Reduced drug use is a meaningful treatment outcome for people with stimulant use disorders

2024-01-10
Reducing stimulant use was associated with significant improvement in measures of health and recovery among people with stimulant use disorder, even if they did not achieve total abstinence. This finding is according to an analysis of data from 13 randomized clinical trials of treatments for stimulant use disorders involving methamphetamine and cocaine. Historically, total abstinence has been the standard goal of treatment for substance use disorders, however, these findings support the growing recognition that a more nuanced perspective on measuring treatment success may be beneficial. The study, published in Addiction, was led by scientists at the Johns Hopkins Bloomberg School of Public ...

Blood test distinguishes neuroendocrine subtype of advanced prostate cancer

Blood test distinguishes neuroendocrine subtype of advanced prostate cancer
2024-01-10
Boston – Like a criminal entering a witness protection program, cancer cells can shed their past and take on a new identity. Detecting such an identity-switch is particularly challenging when metastatic castration-resistant prostate cancer (CRPC) advances from adenocarcinoma to neuroendocrine prostate cancer (NEPC), a very difficult cancer to treat. Now, however, researchers at Dana-Farber Cancer Institute and the University of Trento, Italy, have developed a blood test, described in Cancer Discovery, that can ...

2024-01-10
Québec, January 10, 2024 – In people with amyotrophic lateral sclerosis (ALS), changes in neurons appear to activate immune cells. Lowering the inflammation could reduce the symptoms of the disease, according to a study led by Chantelle Sephton, a professor at Université Laval's Faculty of Medicine.    ALS is caused by the loss of upper motor neurons, located in the brain, and lower motor neurons, which extend from the spinal cord to the muscles. Using a genetically modified mouse ...

PFAS flow equally between Arctic Ocean and Atlantic Ocean, study finds

PFAS flow equally between Arctic Ocean and Atlantic Ocean, study finds
2024-01-10
The frigid Arctic Ocean is far removed from the places most people live, but even so, “forever chemicals” reach this remote landscape. Now, research in ACS’ Environmental Science & Technology Letters suggests that per- and polyfluoroalkyl substances (PFAS) won't stay there indefinitely. Instead, they are transported in a feedback loop, with the Arctic Ocean potentially exporting as many PFAS to the North Atlantic Ocean as it receives, circulating the compounds around the world. To ...

More siblings mean poorer mental health for teens

2024-01-10
COLUMBUS, Ohio – Teens from larger families have poorer mental health than those with fewer siblings, according to a large analysis of children in the United States and China.   The details of the pattern vary depending on factors such as the spacing of sibling ages and the age of the siblings.   But the fact that the overall pattern was found in both countries is striking, said Doug Downey, lead author of the study and professor of sociology at The Ohio State University.   “Our results couldn’t have been easily predicted before we did the study,” Downey said.   “Other studies have shown that having more siblings ...

Study on lamprey embryos sheds light on the evolutionary origin of vertebrate head

Study on lamprey embryos sheds light on the evolutionary origin of vertebrate head
2024-01-10
The origin of the vertebrate skull is a topic of much debate among evolutionary biologists. Some believe that the vertebrate head has developed as a result of modification of the segmental elements of the trunk, such as the vertebrae and somites. On the other hand, others believe that the vertebrate head has evolved as a new, unsegment body part, unrelated to other widely observed embryonic segments somites. Interestingly, previous studies on embryos have revealed the presence of some vestiges of somites ...

Unveiling the reproductive secrets of red-swamp crayfish

Unveiling the reproductive secrets of red-swamp crayfish
2024-01-10
Procambarus clarkii is a crustacean species native to American freshwater bodies. Brought to Japan in the 1920s as a feed for frogs, this crustacean has slowly taken over the Japanese freshwaters by predation and propagation. In fact, in 2023, the red-swamp crayfish was designated as an invasive alien species by the Japanese Ministry of the Environment and of the Agriculture, Forestry and Fisheries. One way to control the growth in population of red-swamp crayfish and the accompanying crisis is to capture the red-swamp crayfish in their reproductive ...

2024-01-10
Research Highlights: Despite drops in overall cardiovascular disease deaths from 1999-2019, cardiovascular disease deaths in which substance use was cited as a contributing factor increased an average of 4% per year, with the death rate accelerating to 6.2% from 2012-2019. Prominent increases in cardiovascular deaths associated with substance use were most notable among women, American Indian or Alaskan individuals, younger individuals, rural area residents and users of cannabis and psychostimulants. Identifying high-risk groups is crucial for prioritizing preventive measures to reduce substance use linked with cardiovascular disease deaths, particularly ...

Noninvasive technique reveals how cells’ gene expression changes over time

2024-01-10
CAMBRIDGE, MA -- Sequencing all of the RNA in a cell can reveal a great deal of information about that cell’s function and what it is doing at a given point in time. However, the sequencing process destroys the cell, making it difficult to study ongoing changes in gene expression. An alternative approach developed at MIT could enable researchers to track such changes over extended periods of time. The new method, which is based on a noninvasive imaging technique known as Raman spectroscopy, doesn’t harm cells and can be performed repeatedly. Using ...
