How Squids and Octopuses Get Their Big Brains – Neuroscience News

Summary: The neural stem cells of cephalopods act similarly to those of vertebrates during the development of the nervous system. Source: Harvard Cephalopods – which include octopus, squid and their cousins ​​the cuttlefish – are capable of some truly charismatic behaviors. They can quickly process information to transform shape, color and even texture, blending into …

Secrets of an earlier universe: Hubble captures a red supergiant supernova from 11 billion years ago

Secrets of an earlier universe: Hubble captures a red supergiant supernova from 11 billion years ago

Thanks to a phenomenon called gravitational lensing, three different moments of a distant supernova explosion have been captured in a single snapshot by NASA’s Hubble Space Telescope. The light from the supernova, located behind the galaxy cluster Abell 370, was multiplied by the immense gravity of the cluster. Credit: NASA, ESA, STScI, Wenlei Chen (UMN), …

‘Fuzzy’ dark matter could form stars in giant ‘pancakes’

An exotic dark matter model suggests that the first stars may have formed not as individuals, but as tiny pockets embedded in gigantic pancake-like sheets. This would have led to the formation of truly gigantic stars that the James Webb Space Telescope may be able to detect, according to a research team. Astronomers have a …

CRISPR for cancer takes a big step forward

CRISPR for cancer takes a big step forward

RResearchers have taken an important step towards a long-desired goal: to use CRISPR gene-editing technology to treat cancer. In a study published in Nature, the scientists recruited 16 people who had previously received standard treatment for their cancer (which included colon, head and neck, lung, skin, etc.) but whose cancers had returned. They wanted to …

Scientists find that gay men are twice as likely to get the disease

The study found that 0.8% of same-sex patients who engaged in high-risk sexual activity had been diagnosed with Crohn’s disease, while only 0.49 heterosexual men who engaged in high-risk sexual activity had Crohn’s disease. The research will enable the development of individualized precision medicine for the management of inflammatory bowel disease in this underrepresented minority …

A single Hubble image captured a supernova at three different times

Enlarge / On the left, the full Hubble image. On the right, various images of the gravitationally lensed object. NASA, ESA, STScI, Wenlei Chen, Patrick Kelly Over the past few decades, we have gotten much better at observing supernovae as they occur. Orbiting telescopes can now pick up emitted high-energy photons and determine their source, …

World’s largest autism whole-genome sequencing study reveals 134 autism-linked genes

Summary: The researchers identified 134 genes associated with autism and a range of genetic alterations associated with ASDs. Notably, the study identified changes in copy number variations with likely associations with ASDs, including autism-associated variants in 14% of people on the autism spectrum. Source: Hospital for sick children Researchers at the Hospital for Sick Children …

New approach may help design shorter, more powerful trials to evaluate drugs for Parkinson's disease

New approach may help design shorter, more powerful trials to evaluate drugs for Parkinson’s disease

Testing whether a new drug has an impact on the progression of Parkinson’s disease takes years, in part because the disease often progresses very slowly. Many patients with Parkinson’s disease experience no worsening of their symptoms during a typical clinical trial, even without treatment. Now Scripps Research scientists have developed a tool that analyzes genetic …
