New CRISPR-based system inserts new DNA without cutting and pasting

Michael Irving June 12, 2019

The CRISPR gene-editing system is a powerful tool, but sometimes cutting and pasting can have unwanted side effects. Now researchers from MIT and Harvard have developed a new CRISPR-based system that can insert new DNA sequences without cutting, which should make the process safer and more accurate.

One-two punch weakens bacteria's defenses against antibiotics

Michael Irving May 1, 2019

Bacteria are quickly evolving resistances to antibiotics, to the extent that our best drugs might not work in the terrifyingly-near future. Now, researchers from Thomas Jefferson University have found a new way to weaken bacterial defenses, slowing down the development of antibiotic resistance.

CRISPR breakthrough uses "hairpin lock" for more precise genetic engineering

Michael Irving April 16, 2019

The CRISPR gene-editing system is incredibly accurate, but it’s not unusual for it to be a little bit off target sometimes. Now, biomedical engineers at Duke University have created an RNA “lock” that can apparently make the system far more precise, and it works with all kinds of CRISPR variations.

The new hairpin lock – blue section at the top left – folds back on itself ...

New evidence suggests life on Earth started in shallow ponds, not deep oceans

Michael Irving April 15, 2019

How did life emerge from non-living matter? The prevailing hypothesis is that life got started in the ocean, where hydrothermal vents provided just the right chemical reactions. But a new MIT study has found that ancient oceans probably didn’t have enough nitrogen – but shallow ponds might have.

A new study gives more evidence that life got started in shallow ponds, not the deep ...

Decade-long study reveals key "master switch" regulating immune system activity

Rich Haridy February 11, 2019

A huge variety of disease essentially stems from a dysfunctional immune system. After ten years of work a new study has revealed, for the first time, the discovery of a molecule that has been found to modulate the immune system’s activity.

It's hoped the discovery of an immune system "master switch" will lead to new clinical treatments ...

Inhalable RNA could breathe new life into lung cancer treatments

Michael Irving January 6, 2019

In the body, mRNA molecules are in charge of instructing cells to produce specific proteins, and hijacking this natural system is emerging as a promising new way to treat a wide variety of illnesses. A new inhalable mRNA aerosol could be a potential new treatment for cystic fibrosis or lung cancer.

Lung epithelial cells that have taken up the mRNA particles (yellow dots), which makes them glow ...

Octopuses on ecstasy and the mummy juice conspiracy: The weirdest science stories of 2018

Rich Haridy December 27, 2018

Science is amazing, but sometimes scientists do get a little niche in their studies. Here is a list of the weirdest science stories we came across this year, from twerking robots to bizarre snail-to-snail memory transference and a fountain-of-youth sarcophagus conspiracy that sums up 2018.

New Atlas looks back at some of the weirder stories from the world of science in ...

Two experimental cancer drugs team up after unexpected discovery

Michael Irving December 4, 2018

Researchers at MIT have combined two experimental cancer drugs, protein kinase inhibitors and ribonuclease drugs, and found that they worked better together than alone. The discovery could help reduce side effects of cancer treatments and make them more effective.

MIT researchers have combined two experimental cancer drugs into one treatment that's more effective than either ...

Cellular kill code discovery may help extinguish cancers

Rich Haridy October 30, 2018

Research has discovered that inside every cell in the human body is a kill code designed to trigger self-destruction if it senses a cell is turning cancerous. Across two studies the scientists homed in on the code underlying this mechanism and believe it may lead to a new kind of cancer treatment.

An ancient mechanism can hopefully be appropriated in the future to develop a new way of ...

Promising new universal flu vaccine may be just a few years away from market

Rich Haridy August 22, 2018

A new study led by researchers at the University of Pennsylvania has demonstrated the efficacy of a new universal flu vaccine. Having been proven impressively effective in animal tests, the team hopes to move the vaccine into human trials within the next couple of years.

Yet another candidate is in the running to be the first safe and effective universal flu ...
