The structure of a molecular junction with noncovalent interaction plays a key role in electron transport, reveals a recent study conducted by researchers at Tokyo Tech. Through simultaneous surface-enhanced Raman scattering and current–voltage measurements, they found that a single dimer junction of naphthalenethiol molecule shows three different bondings, namely π–π intermolecular and through-π and through-space molecule–electrode interactions.
The π–π interaction is a type of noncovalent interaction that occurs when the electron clouds in the π orbitals ...
Researchers report advance in immune therapy against ALS
2023-07-13
New research suggests that targeting autoimmune inflammation associated with amyotrophic lateral sclerosis (ALS) using two drugs, one of them already approved for multiple sclerosis, could be a promising approach for treatment.
ALS, also known as Lou Gehrig's disease, is a progressive neurodegenerative disease that affects the nerve cells in the brain and spinal cord. It leads to the gradual loss of muscle control, eventually resulting in paralysis and difficulty with speech, swallowing, and breathing. The exact cause of ALS is not fully understood, and currently, there is no cure ...

Butterfly species’ big brains adapted giving them a survival edge, study finds
2023-07-13
Heliconius butterflies’ brains grew as they adopted a novel foraging behaviour, scientists at the University of Bristol have found.
A region of their brain, known as the mushroom body due to its shape, are two to four times larger than those of their close relatives.
The findings, published today in Nature Communications, suggest that the structure and function of the nervous system are closely linked to an organism's ecological niche and behaviour.
Dr Stephen Montgomery of Bristol’s School of Biological Sciences explained: “Heliconius are the only butterflies known to collect and digest pollen, which gives them an adult source ...
Combination cancer therapies can shrink tumors and improve survival outcomes for patients with advanced non-small lung cancer
2023-07-13
New Haven, Conn. — While pembrolizumab is an approved treatment for patients with stage III non-small cell lung cancer (NSCLC), only some patients respond to this therapy. Treatment failure, researchers say, is often caused by differences in the tumor microenvironment. An ongoing phase II study (KEYNOTE-495/KeyImPaCT) led by a researcher at Yale Cancer Center reveals that combining pembrolizumab with other treatments reduced the size of target tumors, resulting in a higher response rate for patients with advanced NSCLC.
The new research was published July 10 in Nature Medicine.
