An analysis of the 1.5 million-year-old cranium DAN5/P1, found at the Gona site in Ethiopia, has cranial cranial morphology which indicates that it belongs to the species Homo erectus but near the earliest African stage, where it is sometimes identified using the name H. ergaster.The fossil is very small for these hominin groups and suggest that its cerebral morphology does not present any traits distinctive to the human genus: its proportions are similar to those of australopiths or species whose evolutionary position, and whether they are from our own lineage, remains to be determined, as is the case with H. habilis.

DART, NASA’s successful double asteroid redirection test in September 2022, had an impact greater than engineers expected - and that means the ability to more accurately move asteroids on a collision course will be greater in the future.An analysis of the results found the momentum was significantly enhanced by the recoil created from streams of particles produced by the impact.

If you believe your electric car is not using the 80 percent of electricity generated by conventional fuels, you may also believe the high cost is worth it to save the environment. But there is no running from the environmental problems created by the cars themselves. There can be no sustainable value chain when we haven't had new batteries in 30 years. Unfortunately, as long as mandates and subsidies are in effect, there is no incentive to create better technology, which means the only hope is to reuse old, inefficient batteries in order to mitigate the high social and environmental toll electric cars extract now.

To adult audiences in 1977, "Star Wars" was the most realistic special effects they had ever witnessed while to younger people of today, the defects are obvious. Some of that is due to better technology, a cheap TV has better clarity and resolution that an IMAX screen a generation ago, but some of it is that they are trained to see better.

Imidazole dipeptides have been been linked to beneficial effects such as relieving fatigue and, with far less credibility, preventing dementia, and a new study has found that 2-oxo-imidazole-containing dipeptides (2-oxo-IDPs), which have one more oxygen atom than normal imidazole dipeptides, are the most common variety of imidazole dipeptides derivatives in the body.

With ChatGPT a huge fad, students may be excited that their next paper will be easy, because if it is truly AI it will start from the unique seed you give it. Yet it does not work that way. Language models that generate text in response to user prompts use a lot of the same training materials, which means they can plagiarize content in multiple ways.

COVID-19 has done little to boost vaccination rates against other viruses, according to a new analysis.In a recent survey, just over 50 percent said they had received a flu vaccine, unchanged in a representative national panel from the comparable period last year and within the usual range of years prior to the pandemic. Before people thought COVID-19 was just a bad cold (coronavirus is in the same family and was only declared distinct in the 1960s) they thought the flu was a bad cold. Or believed they were more likely to get the flu if they had a vaccine.

We have a body clock that changes with exposure to sun and a new study finds that while humans don't hibernate, we do sleep longer in the winter. 

It's easy to get a penalty waiver from the federal government if your wind power installation kills an eagle, but if such alternative energy ever becomes more widespread, winged creature deaths of all kinds could be substantial.Current mitigation strategies are efforts like blanket curtailment, which slows blade rotation to less than one revolution per minute at the low wind speeds which have been found to cause the highest number of bat fatalities. Wind power is not viable now, and such an unsophisticated procedure applying a general wind speed threshold for all wind turbines for a longer period of time causes even more loss of energy generation.

For as long as wheat flour has been used for food, a small number of people have been allergic to the gluten in it. These celiac disease sufferers experience stomach pain, nausea and even intestinal damage. More recently, gluten-free food became a new diet craze and while it was ridiculous biologically, it turned gluten-free food into a diverse $4 billion market, which was good for the celiac community.Flour can now be made from banana peels, almonds and various grains and new work adds sweet potatoes into the mix.

A new study found that a cup of coffee with milk may create a combination of proteins and antioxidants that doubles the anti-inflammatory properties in immune cells. That doesn't mean you should listen to 'food is medicine' advocates and start putting dairy in everything, this was a cell study, which is even lower than studies in mice on the human relevance scale.

Thalattosuchians are ancient relatives of the ancestors of modern-day crocodiles, a biological aunt if you will, and part of the head, backbone, and limbs of Turnersuchus hingleyae have been found on what paleontologists call the Jurassic Coast, in Dorset of the United Kingdom.The name derives from Paul Turner and Lizzie Hingley, who discovered the fossil in 2017. The ending “suchus,” is the Latinized form of “soukhos,” Greek for crocodile.
