High-amplitude ultrasound pulses have been used to partially destroy liver tumors in rats, triggering the rodents’ immune systems to clear the remaining cancerous cells and prevent the disease from spreading or returning. Presenting their findings in the journal Cancers, the researchers behind this breakthrough say their technique could lead to effective, non-invasive treatments for some of the most intractable cancers in human patients.

Liver cancer certainly falls into that category, and is associated with a five-year survival rate of just 18 percent in the US. Though many treatment options are available, liver tumors have a tendency to metastasize or recur after these interventions.

In their study, the authors explain that conventional cancer treatments like chemotherapy, radiotherapy, and thermal ablation are effective at destroying tumors, yet also trigger a somewhat unpredictable immune reaction which can be anti-tumor or pro-tumor. Furthermore, they note that the size, location, and stage of a tumor can sometimes make it impossible to target the entire tissue mass with existing treatments.

Elon Musk believes his Neuralink brain chip could help treat morbid obesity. Experts say the billionaire’s dream isn’t as far-fetched as it may seem.

“I don’t think it is any more implausible than other claims for the potential of neurotechnology,” Professor Andrew Jackson, an expert in neural interfaces at Newcastle University, told Insider.

Musk made the suggestion in a TED interview on April 14, thereby adding “morbid obesity” to a growing list of ailments he believes Neuralink could help treat.

Over the course of almost 60 years, the information age has given the world the internet, smart phones, and lightning-fast computers. This has been made possible by about doubling the number of transistors that can be packed onto a computer chip every two years, resulting in billions of atomic-scale transistors that can fit on a fingernail-sized device. Even individual atoms may be observed and counted within such “atomic scale” lengths.

Physical limit

With this doubling reaching its physical limit, the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has joined industry efforts to prolong the process and find new techniques to make ever-more powerful, efficient, and cost-effective chips. In the first PPPL research conducted under a Cooperative Research and Development Agreement (CRADA) with Lam Research Corp., a global producer of chip-making equipment, laboratory scientists properly predicted a fundamental phase in atomic-scale chip production through the use of modeling.
