Rocket Lab flies rocket with pre-flown engine for first time

Posted by in category: space travel

For the first time, Rocket Lab reused one of its Rutherford engines, marking an important step in the road to reusability.

Rocket Lab launched an Electron rocket with a pre-flown Rutherford engine for the first time yesterday, August 23.

The company has experimented with a mid-air helicopter retrieval method, though it has settled on plucking boosters out of the ocean after a parachute-assisted splashdown.

OpenAI introduces fine-tuning capabilities for GPT-3.5 Turbo

Posted by in category: robotics/AI

A fine-tuned version of GPT-3.5 Turbo can outperform GPT-4, said OpenAI.

US-based AI company OpenAI just released the fine-tuning API for GPT-3.5 Turbo. This gives developers more flexibility to customize models that perform better for their use cases. The company ran tests, showing that the fine-tuned versions of GPT-3.5 Turbo can surpass GPT-4’s base capabilities on certain tasks.

OpenAI released gpt-3.5-turbo in March this year as a ChatGPT model family for various non-chat uses. It’s priced at $0.002 per 1k tokens, which the AI company… More.

Jeff Bezos’ Blue Origin responsible for potent gas emission

Posted by in category: space travel

Despite attempts to decrease excessive greenhouse gas emissions, significant methane releases were detected at the rocket site of the e-commerce giant.

Methane (CH4) is responsible for 11.4 percent of greenhouse gas emissions, according to the United States Environmental Protection Agency (EPA). Being the most potent gas, methane was also on the agenda for discussion at the White House.

Increasing the bioavailability of oncology drugs with amorphous solid dosage formulations

Posted by in categories: biotech/medical, food

Oral tyrosine kinase inhibitors (TKIs) are a class of cancer drugs that can be highly susceptible to issues with solubility in the gastrointestinal tract. Most crystalline TKI drugs have pH-dependent solubility that affects their bioavailability in an oral dosage form. Consequently, natural variations in gastric pH, or variations due to eating or taking antacids, can significantly impact drug absorption and, in turn, therapeutic efficacy.

Alternative formulation techniques such as amorphous solid dispersion (ASD) can still deliver the convenience of a pill while reducing TKIs’ sensitivity to physiological variation. This ensures more consistent—and higher—bioavailability. This whitepaper outlines the challenges associated with pH-dependent solubility for oral TKI drugs and reviews how leveraging ASD formulation can help create more effective, patient-friendly drug products.

How AI brings greater accuracy, speed, and scale to microsegmentation

Microsegmentation is table stakes for CISOs looking to gain the speed, scale and time-to-market advantages that multicloud tech stacks provide digital-first business initiatives.

Gartner predicts that through 2023, at least 99% of cloud security failures will be the user’s fault. Getting microsegmentation right in multicloud configurations can make or break any zero-trust initiative. Ninety percent of enterprises migrating to the cloud are adopting zero trust, but just 22% are confident their organization will capitalize on its many benefits and transform their business. Zscaler’s The State of Zero Trust Transformation 2023 Report says secure cloud transformation is impossible with legacy network security infrastructure such as firewalls and VPNs.

Stem Cell Studies Suggest Mechanism by Which Gene Increases Risk of Sporadic Alzheimer’s Disease

Posted by in categories: biotech/medical, neuroscience

A research team headed by investigators at Brigham and Women’s Hospital reported on the results of a study in which they used stem cells from Alzheimer’s disease (AD) patients to identify a potential mechanism by which a gene known as SORL1 may impact the risk for the neurodegenerative disorder. Their work found that loss of normal SORL1 function leads to a reduction in two key proteins, APOE and CLU, which are known to be involved in AD, and which play an essential role in the neurons of healthy individuals. The study findings suggest a potential new strategy for AD treatment, especially for patients not responsive to existing therapies.

“Understanding the subtypes of AD is relatively new in the field of neurology research,” said Tracy Young-Pearse, PhD, of the Ann Romney Center for Neurological Diseases. “This is getting at a precision neurology approach, with which we can better predict which patients may be responsive to Alzheimer’s treatment strategies that attack specific genes or target the problems they cause.” Young-Pearse is corresponding author of the team’s published paper in Cell Reports, which is titled, “ Cell-type-specific regulation of APOE and CLU levels in human neurons by the Alzheimer’s disease risk gene SORL1,” in which they concluded, “Taken together, we demonstrate that AD-relevant SORL1 loss of function results in neuron-specific reduction in APOE and CLU and dysregulated lipid homeostasis.”

AD varies widely in its age of onset, presentation, and severity. Key neurological features of AD, including the accumulation of amyloid-beta (Aβ) plaques in the brain, also vary across individuals. The anti-amyloid therapies, aducanumab and lecanemab, have received FDA accelerated and traditional approval, respectively, but not all patients respond to these drugs, warranting other treatment options.
