Is anyone interested in a mini-sub?
Elon Musk brought his new lifesaving mini-submarine to Thailand to help save 13 people trapped inside a cave, but rescuers didn’t use it. Here’s what’s next for Musk’s latest invention.

A new study by the Yale scientists, taking insulin or the most commonly used drug for type 2 diabetes, metformin, failed to either delay or effectively treat the condition in youth.
In the study, dubbed as Restoring Insulin Secretion (RISE) Pediatric Medication Study, scientists explored the impact of two medications for pre-diabetes or diabetes in youth aged 10 to 19. The children and teens either took infusions of insulin for three months, trailed by metformin for a year, or metformin alone. Amid the 15-month contemplate period, the analysts surveyed glucose levels of study members and also the capacity of their beta cells, which store and discharge insulin keeping in mind the end goal to keep up solid glucose.
Scientists discovered that the medications neglected to moderate or stop the progression of type 2 diabetes in either group. The working of the adolescents’ beta cells kept on breaking down in spite of the treatments, which have been appealed to treat write 2 diabetes adequately in adults.

Soaring global need for cooling by 2050 could see world energy consumption for cooling increase five times as the number of cooling appliances quadruples to 14 billion—according to a new report by the University of Birmingham, UK.
This new report sets out to provide, for the first time, an indication of the scale of the energy implications of ‘Cooling for All’.
Effective cooling is essential to preserve food and medicine. It underpins industry and economic growth, is key to sustainable urbanisation as well as providing a ladder out of rural poverty. With significant areas of the world projected to experience temperature rises that place them beyond those which humans can survive, cooling will increasingly make much of the world bearable—or even safe—to live in. With populations increasing, expanding urbanisation and climate change impacts leading to more frequent heatwaves and temperature rises, the demand for more cooling will increase in the decades ahead.

Researchers isolated several mutations leading to melanoma and reproduced them in the lab using CRISPR.
Two papers authored by researchers at the University of California, San Francisco described the genetic changes that turn harmless moles into malignant melanomas and the experiment they devised to recreate the step-by-step evolution of normal skin cells into cancer cells [1], [2].
Summary ([1])
We elucidated genomic and transcriptomic changes that accompany the evolution of melanoma from pre-malignant lesions by sequencing DNA and RNA from primary melanomas and their adjacent precursors, as well as matched primary tumors and regional metastases. In total, we analyzed 230 histopathologically distinct areas of melanocytic neoplasia from 82 patients. Somatic alterations sequentially induced mitogen-activated protein kinase (MAPK) pathway activation, upregulation of telomerase, modulation of the chromatin landscape, G1/S checkpoint override, ramp-up of MAPK signaling, disruption of the p53 pathway, and activation of the PI3K pathway; no mutations were specifically associated with metastatic progression, as these pathways were perturbed during the evolution of primary melanomas. UV radiation-induced point mutations steadily increased until melanoma invasion, at which point copy-number alterations also became prevalent.
Do you want to join in the fight to end age-related disease?
Request for Proposals (RFP)
In cooperation with the Forever Healthy Foundation, SENS Research Foundation (SRF) is inviting candidates to submit research proposals for a Fellowship in Rejuvenation Biotechnology that would be undertaken at our Research Center (RC) in Mountain View, California.
SRF pursues the development of therapies to prevent and reverse age-related disease and disability through a “damage-repair” paradigm: developing interventions that maintain and restore the structural and functional integrity of tissues by directly removing, repairing, replacing, or rendering harmless the cellular and molecular damage of aging. Applications are requested that promise progress in regenerative medicine for the prevention and reversal of age-related disease.

Researchers used magnetically driven microrobots to carry cells to predetermined spots within living zebrafish and mice, they report in Science Robotics today (June 27). The authors propose using these hair-width gadgets as delivery vehicles in regenerative medicine and cell therapy.
The scientists used a computer model to work out the ideal dimensions for a microrobot; spiky, porous, spherical ones were deemed best for transporting living cells. They printed the devices using a 3D laser printer and coated the bots with nickel and titanium to make them magnetic and biocompatible, respectively. An external magnetic field applied to the animal then leads the microrobots.
To begin with, the research team tested the ability for the robots to transport cells through cell cultures, blood vessel–like microfluidic chips, and in vivo in zebrafish. Further, they used these microrobots to induce cancer at a specific location within mice by ferrying tumor cells to the spot. The team observed fluorescence at the target site as the labeled cancer cells proliferated.

Tactical Robotics’ Cormorant drone design allows it to navigate tight areas where a helicopter’s blades would get caught on the environment. The remote-controlled military drone can transport two injured people from a battle zone. The Israeli-based company believes the drone could one day also be used to inspect bridges, deliver medical supplies and spray crops.
