Since the Nobel prize for chemistry was awarded to biochemist Jennifer Doudna and microbiologist Emmanuelle Charpentier in 2020, for developing the gene-editing technique known as Crispr-Cas9, Crispr has enjoyed a lot of attention and interest from scientists. The technique has been touted as a possible source of new treatments for diseases caused by genetic mutations, such as muscular dystrophy, and congenital blindness.
"All The President's Men" inspired young people to rush to journalism while "Mad Men" caused enrollment in advertising courses to surge and "Top Gun led to more Navy recruits.
Film and television shapes young minds and marketers know it. A whole generation of people will believe a show like "The Offer" is a history of "The Godfather" film the same way some believe "Food Inc" is science; because it is on a screen. Yet trends have changed as fashions have. 'Stewardess' is out of the lexicon while 'Congressman' is still in.
A new study finds that hugging a romantic partner can prevent the acute stress response of female bodies.
Women who embrace their romantic partner prior to undergoing a stressful experience had lower levels of the stress hormone cortisol in saliva compared to women who did not embrace their partner. No effect was found for men.
Some papers have claimed that massages, embraces combined with hand-holding, and embraces combined with affectionate communication can reduce signs of stress in women but those usually do not include men nor any effects of a brief embrace.
In the 16th century, it was shown by Paracelsus that 'the dose makes the poison' - too much medicine or anything else could kill while too little did nothing. In the 21st century activists have sought to dispel that. They claim homeopathic effects from chemicals at safe doses, endocrine distuption and u-shaped curves, but science knows better.
The recent precise measurement of the W boson mass produced by the non-dead CDF collaboration last month continues to be at the focus of attention by the scientific community, for a good reason - if correct, the CDF measurement in and of itself would be the conclusive proof that our trust in the Standard Model of particle physics when producing predictions of particle phenomenology needs a significant overhaul.
This was an opportunity for the public to give your feedback to NASA about their Mars sample return mission plans - can submit your comments to NASA here as a public comment.
This is for their draft environmental impact statement which they plan to submit later this year.

At the centere of our galaxy, the Milky Way, there exists what must be a black hole. But detecting it has been challenging because of the cosmic dust around it.
Now, for the first time, a group of radio antennas knows as the Event Horizon Telescope Collaboration have unveiled the first image of the supermassive black hole four million times more massive than our Sun.
known as Sagittarius A* (Sgr A*, pronounced "sadge-ay-star") it obviously can't be seen, that is built into the black hole name, but it can be inferred thanks to a dark central region (called a “shadow”) surrounded by a bright ring-like structure. The new view captures light bent by the powerful gravity of the black hole.
Despite shutting down its operations in 2011, data from an old experiment at the Collider Detector at Fermilab (CDF) has pushed scientists to further rethink the Standard Model.
Mars doesn’t have tectonic plates like Earth, but it does have volcanically active regions that can cause rumbles, and one way to develop a better understanding of Mars’ mantle and core is to examine seismic active. In March, NASA’s InSight lander detected two strong, clear quakes originating in a location of Mars called Cerberus Fossae – the same place where two strong quakes were seen earlier in the mission. Those quakes have magnitudes of 3.3 and 3.1; the previous quakes were magnitude 3.6 and 3.5.
InSight has recorded over 1,300 quakes to date, but nothing like the magnitude 5 temblor that occurred on May 4, 2022. That is a medium-sized earthquake on Earth, they happen 5 times each day, but it is a size researchers only hoped to get during this mission on Mars.
