New quasi-particle discovered: The Pi-ton
New particles are usually only found in huge particle accelerators. But something quite similar can be found in a simple lab or in computer simulations: a quasiparticle.

Np4A alarmones function in bacteria as precursors to RNA caps [Biochemistry]
Stresses that increase the cellular concentration of dinucleoside tetraphosphates (Np4Ns) have recently been shown to impact RNA degradation by inducing nucleoside tetraphosphate (Np4) capping of bacterial transcripts. However, neither the mechanism by which such caps are acquired nor the function of Np4Ns in bacteria is known. Here we report that…

Energy dissipation bounds for autonomous thermodynamic cycles [Biophysics and Computational Biology]
How much free energy is irreversibly lost during a thermodynamic process? For deterministic protocols, lower bounds on energy dissipation arise from the thermodynamic friction associated with pushing a system out of equilibrium in finite time. Recent work has also bounded the cost of precisely moving a single degree of freedom….

Developing B cells can be positively or negatively selected by self-antigens, but the mechanisms that determine these outcomes are incompletely understood.

The new observations have identified 71 variable stars in this region and provided essential information about their properties. Results of the study were presented in a paper published January 24 on arXiv.org.

New synthetic route for amanitin, a therapeutically interesting mushroom toxin
The death cap mushroom is highly toxic. However, some of its toxins can also be healing: amanitins are potential components for antibody-based cancer treatments. In the journal Angewandte Chemie, German scientists have now introduced a new synthetic route for α-amanitin. Their method seems suitable for production on a larger scale, finally making enough of the toxin available for further research.

Therefore, identifying DNA that causes genetic disorders gives researchers and clinicians a better understanding of how to treat inherited diseases and possibly prevent the diseases from being passed down to future generations.

Rapid weather swings increase flu risk
New research shows that rapid weather variability as a result of climate change could increase the risk of a flu epidemic in some highly populated regions in the late 21st century.

Physics of giant bubbles bursts secret of fluid mechanics
A study inspired by street performers making gigantic soap bubbles led to a discovery in fluid mechanics: Mixing different molecular sizes of polymers within a solution increases the ability of a thin film to stretch without breaking.

High and low exercise intensity found to influence brain function differently
A new study shows for the first time that low and high exercise intensities differentially influence brain function. Using resting state functional magnetic resonance imaging (Rs-fMRI), a noninvasive technique that allows for studies on brain connectivity, researchers discovered that low-intensity exercise triggers brain networks involved in cognition control and attention processing, while high-i

Researchers discover new piece of the puzzle for Parkinson's disease
Biomedical scientists have discovered that a defect in the ATP13A2 gene causes cell death by disrupting the cellular transport of polyamines. When this happens in the part of the brain that controls body movement, it can lead to Parkinson's disease.

Cells' springy coils pump bursts of RNA
Models by chemists calculate the chemical and mechanical energies involved in 'bursty' RNA production in cells. Their models show how RNA polymerases create supercoils of DNA allowing production of RNA that goes on to produce proteins.

City in a test tube: Researchers simulate urban pollution to show how it damages the heart
A unique study mimicking city centre pollution levels shows how just two hours of bad air adversely affects the heart and blood vessels for a whole day.

Smaller detection device effective for nuclear treaty verification, archaeology digs
Most nuclear data measurements are performed at accelerators large enough to occupy a geologic formation a kilometer wide. But a portable device that can reveal the composition of materials quickly on-site would greatly benefit cases such as in archaeology and nuclear arms treaty verification. New research used computational simulations to show that with the right geometric adjustments, it is poss

Infectious disease experts warn of outbreak risks in US border detention centers
Over the past year, at least seven children have died from diseases including influenza while being detained by the US Department of Homeland Security's Customs and Border Protection (CBP) agency. Infectious disease experts have called for protections like influenza vaccinations to prevent serious outbreaks.

How the development of skulls and beaks made Darwin's finches one of the most diverse species
Darwin's finches are among the most celebrated examples of adaptive radiation in the evolution of modern vertebrates and now a new study, led by scientists from the University of Bristol, has provided fresh insights into their rapid development and evolutionary success.

A fundamental discovery about how gene activity is regulated
Researchers at Johns Hopkins Bloomberg School of Public Health have discovered a fundamental mechanism that regulates gene activity in cells. The newly discovered mechanism targets RNA, or ribonucleic acid, a close cousin of DNA that plays an important role in cellular activity.

The Contrarian Who Cures Cancers
When I first met the immunology researcher James P. Allison in 2014, he was just becoming an icon. Columbia University had brought him to its campus to present him with the Louisa Gross Horwitz Prize for the new type of cancer therapy he had developed. Instead of trying to burn, poison or surgically remove malignant cells from the body, his treatment mobilized a patient's immune system to destroy

Cheap nanoparticles stimulate immune response to cancer in the lab
Researchers have developed nanoparticles that, in the lab, can activate immune responses to cancer cells. If they are shown to work as well in the body as they do in the lab, the nanoparticles might provide an effective and more affordable way to fight cancer.
