Immunotherapy is a new, groundbreaking approach to treating cancer that harnesses the body’s own natural defenses to fight tumors. Immunotherapy comes in many forms, including checkpoint inhibitors, which shut down a tumor’s ability to be invisible to the body’s immune system; antibodies that can stick to and attack a tumor; and genetically manipulated cells that become “natural killer cells.”

Ted Teknos, MD, President and Scientific Director of UH Seidman Cancer Center, explains how these medical wonders work and which cancers immunotherapies are most effective at treating. (a Podcast or a  long read)

The early morning wake-up has even become a TikTok trend coined the “five-to-nine before the nine-to-five,” where video montages illustrate a slow morning aesthetic of self-affirmations, workouts, and maybe even a head start into planning for the work day. It can make the rest of the world feel lazy. 

“The pressure to be a morning person is pretty intense,” says Samantha Snowden, a mindfulness teacher at Headspace, the popular meditation app. 

So, will waking up at 5 a.m. make all the difference to your day? Some experts say yes.

For starters, getting up earlier can improve confidence, Snowden says because it can feel like an accomplishment. And there’s something to be said for not constantly feeling like you’re in a rush, which only elevates stress levels and negatively impacts mental health.  

“It’s like always feeling like you are behind in a race you can’t possibly win, which isn’t useful for motivation or positivity,” says ​​Dr. Nikole Benders-Hadi, a psychiatrist based in New York and the medical director of behavioral health at Included Health, about the typical workday morning.

Humans come in a rainbow of hues, from dark chocolate browns to nearly translucent whites.

This full kaleidoscope of skin colors was a relatively recent evolutionary development, according to biologists, occurring alongside the migration of modern humans out of Africa between 100,000 and 50,000 years ago.

The consensus among scientists has always been that lower levels of vitamin D at higher latitudes  — where the sun is less intense — caused the lightning effect when modern humans, who began darker-skinned, first migrated north.

But other factors might be at work, a new study suggests. From the varying effects of frostbite to the sexual preferences of early men, a host of theories have been reviewed.

Vitamin iDea

Vitamin D plays an important role in bone growth and the body’s natural protection against certain diseases, and the inability to absorb enough in areas of less-powerful sunlight would have decreased life expectancies in our African ancestors. The further north they trekked, the more vitamin D they needed and the lighter they got over the generations, due to natural selection.

This explanation accounts for the world’s gradients of skin color traveling south to north, the prevalence of vitamin D deficiency among African immigrants to higher latitudes, as well as the relatively darker skin of Canada’s Inuit peoples, who have good levels of vitamin D despite living in the Arctic, due to their diet rich in oily fish.

So do look up, contrary to the title of the killer-comet movie “Don’t Look Up.”

Discovered less than a year ago, this harmless green comet already is visible in the northern night sky with binoculars and small telescopes, and possibly the naked eye in the darkest corners of the Northern Hemisphere.

It’s expected to brighten as it draws closer and rises higher over the horizon through the end of January, best seen in the predawn hours. By Feb. 10, it will be near Mars, a good landmark. Skygazers in the Southern Hemisphere will have to wait until next month for a glimpse.

Police surveillance and body cameras captured the killing of 29-year-old Tyre Nichols by officers in Memphis, Tennessee, in stark and gruesome detail. The footage Memphis police released Friday shows officers punching, kicking, and pepper spraying Nichols, as well as striking him with a police baton. Nichols died three days after the Jan. 7 attack.

Memphis prosecutors have now charged five officers with Nichols’ murder and other crimes, based in part off the body camera footage. But the case is a stark reminder that such cameras, now used widely in the U.S. and touted as a way to reduce officer misconduct, have a decidedly mixed track record.

Body camera footage has been used to prosecute officers in high-profile cases of excessive force — including the conviction of former Minneapolis police officer Derek Chauvin for murder and manslaughter in the death of George Floyd. But studies split over whether the cameras actually deter police misbehavior. A meta-analysis of 70 studies in 2019 found no evidence that body cameras significantly reduced police misconduct, while a 2021 study found a small but measurable drop in the use of force by officers wearing cameras.

“When body cameras were first rolled out in large numbers starting in 2016, there was a hope that they would help to advance public safety because police officers would behave better if they knew their actions were being monitored and recorded,” said Chad Marlow, senior policy counsel at the ACLU. “The murder of Tyre Nichols provides yet more proof that those hopeful predictions were wrong. In hindsight, body cameras have proven to have a limited and inconsistent value when it comes to holding officers accountable for their misconduct, and virtually no beneficial effect in preventing misconduct in the first place.”

Humans are exceptionally diverse, but we all have something in common: We’re Homo sapiens, and we share a common ancestor. But the story of how we arose, spread around the globe, and acted along the way is still emerging as scientists find new clues. Below are 10 remarkable things we learned about ancient humans in 2022, and how they affect our understanding of humanity’s journey.
