With the aid of mathematics, materials chemistry enables dimension travel, unveiling that all properties of materials are governed by their dimension.

A Detailed comparative study on the structures and electrical properties of related insulators and superconductors

Induction into the Hall of Master Academic Clinicians is the highest accolade for clinical faculty at the SingHealth Duke-NUS Academic Medical Centre. Exemplary clinical faculty members are selected by a special committee for their subject matter mastery, academic excellence and exceptional mentoring for Duke-NUS students.

Scientists have developed a prototype sensor that could help doctors rapidly measure adenosine triphosphate (ATP) and lactate levels in blood samples from patients, aiding in the rapid assessment of the severity of some diseases.

Using electricity, a new method offers the possibility of recycling CO2 while also performing a notoriously difficult reaction, producing compounds potentially useful for drug development.

In a recent study published in the journal ACS Catalysis researchers from Kanazawa University describe novel scanning electrochemical cell microscopy measurements to determine sites of photoelectrochemical activity in titanium dioxide nanotubes.

Giants in History: Barry Paw (29 August 1962 – 28 December 2017) was a biologist and oncologist born in Myanmar who discovered several novel genes and their functions in red blood cells.

This is a novel study that attempted to construct a pH-sensitive delivery system into T cells and their subsets using carboxy-terminal Phe- and CHex-modified dendrimers with different structures, i.e. PAMAM-CHex-Phe and PAMAM-Phe-CHex. The findings contribute to the development of nanoplatforms for direct delivery to T cells to control the functions of T cells, which play key roles in cancer immunotherapy. This is the first report on direct delivery into T cells using pH-sensitive DDS.

Simulations have led to the fabrication of a polymer-DNA gel that could be used in tissue regeneration and robotics.

Through numerical simulations, a researcher details the discovery of a new isolated skyrmion with a half-integer topological quantum number in the ferromagnetic phase of the magnetic quantum fluid Bose-Einstein condensate (BEC). The new skyrmion is generated by applying a spin current to a magnetic domain wall and it has an eccentric (off-center) spin singularity inside it.

Helping elevate the careers of over 50 women researchers, the partnership has recognized prize-winning science from more than 20 countries in the Global South since 2013

Giants in History: Eminent Filipina scientist and educator Clara Lim-Sylianco (18 August 1925 – 23 July 2013) is remembered for her extensive research on mutagens – often-carcinogenic agents that permanently alter genetic materials such as DNA – antimutagens and bioorganic mechanisms.

The Sanriku Coast - which includes present day Iwate and parts of Aomori and Miyagi - has been prone to tsunamis throughout its history. Analyses of tsunami deposits along the coast, however, haven’t always provided conclusive findings. Now, a research team has utilized a new radiocarbon dating method to clarify the region’s tsunami history and better understand the frequency at which these disasters occur.

Researchers from Institute of Industrial Science, The University of Tokyo find that the occurrence of red snow is closely tied to the length of the snow melt season and new snowfall events

Garden soil houses a variety of bacteria and their natural byproducts — including one that may help halt tumor growth. Lankacidins are molecules that can be isolated from Strepomyces rochei, a common bacterium in soil. In addition to antimicrobial properties, a type of lankacidins, called lankacidin C, can inhibit tumor activity in various cancer cell lines, including leukemia, melanoma, ovarian and breast cancers. Lankacidin C offers a potential foundation on which to design anticancer drugs, but its structure is complicated and difficult to manipulate, according to an international research group. The same group recently identified where antitumor activity is housed on the molecule and has now used that information to simplify lankacidin as a potential starting point to engineer treatments.

Aromaticity of the Space Surrounded by Two Aromatic Rings

Kavli IPMU and UC Berkeley's Hitoshi Murayama has been named a new fellow of the American Association for the Advancement of Science (AAAS). Congratulations!

Researchers have developed an innovative catalyst for the synthesis of propylene, which has potential benefits for the chemical industry and carbon recycling.

An international research group demonstrated that the Kondo effect can have a significant impact on transition metal oxide compound, which has unique and desirable properties to realize wide range of quantum phenomena. The findings have provided more evidence in a decade long debate.

Giants in History: In 1939, biochemist Kamala Sohonie (18 June 1911 – 28 June 1998) became the first woman to be accepted into the Indian Institute of Science (IISc).

Studying the sensory organs of a 100-million-year-old cockroach offers new insights into how the species may have lived.

A ring-expanded porphyrin, diazuliamethyrin, was successfully synthesized via a “3+3” condensation method. This porphyrin showed a 24pi non- or antiaromatic character. We analyzed the optical and electronic structures using magnetic circular dichroism spectroscopy and time-dependent density functional theory calculations.

A specific deep neural network model called Bidirectional Long-Short-Term Memory can use cough sounds to distinguish sick from healthy children, paving the way for preliminary screening.

A study led by Hong Kong Baptist University (HKBU) has revealed that different degrees of exposure to bisphenol S (BPS), an industrial chemical widely used in paper products and plastic containers, are associated with the growth and deterioration of breast tumours in a mouse model. The research results suggest the need for more in-depth and comprehensive research on the potential negative impact of BPS on human health, and the ongoing search for a safer alternative for use in industrial production may be warranted.

A new method for creating a highly useful chemical subunit eliminates the need for precious metals, potentially leading to the sustainable production of pharmaceuticals and electronics.
