Big deals confirm renewed interest in radiopharmaceuticals

Two billion-dollar acquisitions in late December 2023 confirmed renewed interest in radiopharmaceuticals from big pharma companies. The deals highlight the potential for growth in this class of targeted cancer therapeutics. On 26 December, Bristol Myers Squibb agreed to buy RayzeBio for $4.1 billion (£3.2 billion), and a day later Eli Lilly completed its $1.4 billion […]

Boron cluster family breaks electron counting rules

Scientists have isolated a new class of osmaborane clusters that defy the Wade–Mingos electron counting rules. Kenneth Wade first proposed what are now known as the Wade–Mingos electron counting rules in 1971 before Michael Mingos went on to develop them further. The rules predict and order metallaborane clusters by correlating the number of framework electrons […]

Machine learning could ‘change the paradigm’ for polaritonic chemistry

Machine learning models have given a never-before-seen glimpse into the intricate and mysterious mechanics of reactions driven by light–matter hybrid interactions. The techniques are a powerful new tool for scientists working in the field of polaritonic chemistry, which explores the interactions between light and matter on a quantum level. ‘Controlling a chemical reaction is quintessential […]

Science community must become more resilient to global crises, says report

As the impacts of global crises such as war and natural disasters are felt around the world, a new report from the International Science Council (ISC) says that the scientific community should be better prepared to safeguard science and scientists in such challenging situations. ‘Critically, the report comes at a time when schools, universities, research […]

Iron salts catalyse the creation of carbenes for cyclopropanation

A new synthetic strategy uses a simple salt – iron chloride – to catalyse the creation of carbenes from commercial aldehydes. The carbenes quickly react with different alkenes to yield a selection of cyclopropanes ‘with a remarkable structural diversity’, according to Marc Montesinos Magraner, an expert in synthetic chemistry at the University of Valencia, Spain, […]

Creating reconfigurable fluidic devices from liquid building blocks

Reconfigurable functional liquid devices have been created by assembling and disassembling different types of liquid droplets. Liquid droplets such as silicone oil were printed into a range of structures and then liquids could be pumped through them, allowing bespoke fluidic devices to be made. Inspired by toy building blocks, the researchers from Southeast University in […]

From τὰ φυσικά (ta physika) to physics – XVI

As astrology was one of the very first scientific disciplines to be adopted by the ‘Abbāsid in their assimilation of Persian cultural it followed automatically that that they also adopted astronomy; you need astronomy in order to do astrology. Also, the practice of Islam itself required both the determination of the times for the five daily prayers […]

Kinky findings drive crystal growth paradigm shift claim

US chemists say that their new results ‘refute and replace the dominant idea’ of how individual molecules come together to form crystals. Peter Vekilov from the University of Houston and colleagues provide fundamental insights into how dissolved molecules add to growth sites, called kinks, once they get there. They provide new evidence that temporary bonds […]
