Radiopharmaceuticals Emerging as New Cancer Therapy

Posted by in category: biotech/medical

Radiation therapy was first used to treat cancer more than 100 years ago. About half of all cancer patients still receive it at some point during their treatment. And until recently, most radiation therapy was given much as it was 100 years ago, by delivering beams of radiation from outside the body to kill tumors inside the body.

Though effective, external radiation can also cause collateral damage. Even with modern radiation therapy equipment, “you have to [hit] normal tissue to get to a tumor,” said Charles Kunos, M.D., Ph.D., of NCI’s Cancer Therapy Evaluation Program (CTEP). The resulting side effects of radiation therapy depend on the area of the body treated but can include loss of taste, skin changes, hair loss, diarrhea, and sexual problems.

Now, researchers are developing a new class of drugs called radiopharmaceuticals, which deliver radiation therapy directly and specifically to cancer cells. The last several years have seen an explosion of research and clinical trials testing new

Scientists reprogrammed bacteria to be immune to viruses

Posted by in category: biotech/medical

Scientists created a synthetic genome for a bacterium by stringing together building blocks of DNA — and the new genome made the microbe immune to viral infection.

Even when exposed to a cocktail of bacteriophages — viruses that infect bacteria — the designer Escherichia coli remained unscathed, while an unmodified version of the bacterium quickly succumbed to the viral attack and died, the research team reported in their new study, published Thursday (June 3) in the journal Science. That’s because viruses usually hijack a cell’s internal machinery to make new copies of themselves, but in the designer E. coli, that machinery no longer existed.

China’s gigantic multi-modal AI is no one-trick pony

Posted by in categories: robotics/AI, supercomputing

When Open AI’s GPT-3 model made its debut in May of 2020, its performance was widely considered to be the literal state of the art. Capable of generating text indiscernible from human-crafted prose, GPT-3 set a new standard in deep learning. But oh what a difference a year makes. Researchers from the Beijing Academy of Artificial Intelligence announced on Tuesday the release of their own generative deep learning model, Wu Dao, a mammoth AI seemingly capable of doing everything GPT-3 can do, and more.

First off, Wu Dao is flat out enormous. It’s been trained on 1.75 trillion parameters (essentially, the model’s self-selected coefficients) which is a full ten times larger than the 175 billion GPT-3 was trained on and 150 billion parameters larger than Google’s Switch Transformers.

In order to train a model on this many parameters and do so quickly — Wu Dao 2.0 arrived just three months after version 1.0’s release in March — the BAAI researchers first developed an open-source learning system akin to Google’s Mixture of Experts, dubbed FastMoE. This system, which is operable on PyTorch, enabled the model to be trained both on clusters of supercomputers and conventional GPUs. This gave FastMoE more flexibility than Google’s system since FastMoE doesn’t require proprietary hardware like Google’s TPUs and can therefore run on off-the-shelf hardware — supercomputing clusters notwithstanding.

[Video] Inside Asia’s first underground seed vault

But the above-ground structure of the Baekdu-daegan Seed Vault belies the true size of this sprawling underground structure.

The idea of building a Seed Vault in South Korea initially began with the Nagoya Protocol on Access and Benefit Sharing in 2010. Officially launched in 2016 and designated a national security facility since 2019, the Baekdu-daegan Seed Vault’s main purpose is to secure biodiversity from threats such as natural disasters, climate change and war, to support sustainable life for human beings.

Exchange Servers Targeted by ‘Epsilon Red’ Malware

Posted by in categories: cybercrime/malcode, encryption

REvil threat actors may be behind a set of PowerShell scripts developed for encryption and weaponized to exploit vulnerabilities in corporate networks, the ransom note suggests.

Threat actors have deployed new ransomware on the back of a set of PowerShell scripts developed for making encryption, exploiting flaws in unpatched Exchange Servers to attack the corporate network, according to recent research.

Researchers from security firm Sophos detected the new ransomware, called Epsilon Red, in an investigation of an attack on a U.S.-based company in the hospitality sector, Sophos Principal Researcher Andrew Brandt wrote in a report published online.

Scientists Say They’ve Finally Sequenced the Entire Human Genome. Yes, All of It

Posted by in categories: biotech/medical, futurism

This is a technological triumph.


Twenty-one years ago, researchers announced the first “draft” of sequencing the complete human genome. It was a monumental achievement, but the sequence was still missing about 8 percent of the genome. Now, scientists working together around the world say they’ve finally filled in that reclusive 8 percent.

If their work holds up to peer review and it turns out they really did sequence and assemble the human genome in its entirety, gaps and all, it could change the future of medicine.

NASA is going back to Venus after 30 years for an apocalyptic reason

Posted by in categories: climatology, space

Two missions will study the hellish planet to piece together its climate past, look for volcanoes, and see if it was ever habitable.


NASA Administrator and former astronaut Senator Bill Nelson announced today that the agency would be sending two missions to Venus. The two missions, called DAVINCI+ and VERITAS, will respectively study the planet’s atmosphere and geological history.

NIH scientists say they may have found a promising new oral antiviral drug for Covid

Posted by in categories: biotech/medical, health

Scientists may have found a promising new treatment for Covid-19 after an experimental oral antiviral drug demonstrated the ability to prevent the coronavirus from replicating, the National Institutes of Health said Thursday, citing a new study.

The drug, called TEMPOL, can reduce Covid-19 infections by impairing an enzyme the virus needs to make copies of itself once it’s inside human cells, which could potentially limit the severity of the disease, researchers at the NIH said. The drug was tested in an experiment of cell cultures with live viruses.

“We urgently need additional effective, accessible treatments for COVID-19,” Dr. Diana W. Bianchi, director of the NIH’s National Institute of Child Health and Human Development, wrote in a statement. “An oral drug that prevents SARS-CoV-2 from replicating would be an important tool for reducing the severity of the disease.”
