US develops method to spot illegal nuclear material origins in 30 mins
A simple instrument like mass spectrometer can revolutionize how unknown samples are investigated in the future.
A new method developed by researchers at the Los Alamos National Laboratory (LANL) can spot the origins of illegal nuclear material in just 30 minutes. Requiring only a relatively simple instrument, such as a mass spectrometer, the method can help identify the source of any nuclear material outside regulatory control.
According to the International Atomic Energy Agency (IAEA), theft or improper disposal can result in nuclear and radiological material falling out of regulatory control. In 2,024,124 such incidents were reported to the IAEA, of which at least three were linked to “trafficking or malicious use”
Earlier this year, a leader of a crime syndicate pleaded guilty to trafficking nuclear material in a New York court. The accused had discussed sale of yellowcake uranium with an undercover agent.
Intravascular immune surveillance against viremia requires spatiotemporal coordination between Kupffer cells and ILC1s
Zhang et al. reveal that hepatic ILC1s rapidly transition from intravascular patrolling to motility arrest upon encountering infected Kupffer cells (KCs) during viremia. This behavioral switch, driven by cell intrinsic type I IFN signaling and coupled to ILC1 activation, fortifies the antiviral function of KCs to restrict systemic viral dissemination.
Tiny particles ‘surf’ microcosmic waves to save energy in chaotic environments
Conditions can get rough in the micro- and nanoworld. For example, to ensure that nutrients can still be optimally transported within cells, the minuscule transporters involved need to respond to the fluctuating environment. Physicists at Heinrich Heine University Düsseldorf (HHU) and Tel Aviv University in Israel have used model calculations to examine how this can succeed. They have now published their results—which could also be relevant for future microscopic machines—in the journal Nature Communications.
Long-hypothesized dynamic transition seen in deeply supercooled water for the first time
In a new study published in Nature Physics, researchers have achieved the first experimental observation of a fragile-to-strong transition in deeply supercooled water, resolving a scientific puzzle that has persisted for nearly three decades.
Water has anomalous properties when cooled below freezing without crystallization. Previous studies have tracked how water’s viscosity changes with temperature, predicting it would diverge to infinity around ~227 K (−46°C), meaning liquid water’s motion would essentially freeze.
However, this prediction conflicted with other known properties of water. As a result, scientists proposed that the viscosity trend must undergo a change at a specific low temperature—the so-called fragile-to-strong transition (FST).
