Published Artificial Intelligence from a psychologist's point of view
(via sciencedaily.com) Researchers test cognitive abilities of the language model GPT-3.
Published Will future computers run on human brain cells?
(via sciencedaily.com) A 'biocomputer' powered by human brain cells could be developed within our lifetime, according to researchers who expect such technology to exponentially expand the capabilities of modern computing and create novel fields of study.
Published Climate trends in the west, today and 11,000 years ago
(via sciencedaily.com) What we think of as the classic West Coast climate began just about 4,000 years ago, finds a study on climate trends of the Holocene era.
Published Tiny new climbing robot was inspired by geckos and inchworms
(via sciencedaily.com) A tiny robot that could one day help doctors perform surgery was inspired by the incredible gripping ability of geckos and the efficient locomotion of inchworms.
Published Real or fake text? We can learn to spot the difference
(via sciencedaily.com) While apprehensions about employment and schools dominate headlines, the truth is that the effects of large-scale language models such as ChatGPT will touch virtually every corner of our lives. These new tools raise society-wide concerns about artificial intelligence's role in reinforcing social biases, committing fraud and identity theft, generating fake news, spreading misinformation and more. A team of researchers is seeking to empower tech users to mitigate these risks. The authors demonstrate that people can learn to spot the difference between machine-generated and human-written text.
Published Clues about the Northeast's past and future climate from plant fossils
(via sciencedaily.com) A team of researchers is working to understand the details of the climate for the eastern portion of the United States from the Miocene, which unfortunately is a blank spot on paleo-climate maps. New findings suggest the future climate will be very close to the warmer, wetter, and more homogeneous climate similar to conditions experienced 5 million years ago.
Published Early Cretaceous shift in the global carbon cycle affected both land and sea
(via sciencedaily.com) Geologists doing fieldwork in southeastern Utah's Cedar Mountain Formation found carbon isotope evidence that the site, though on land, experienced the same early Cretaceous carbon-cycle change recorded in marine sedimentary rocks in Europe. This ancient carbon-cycle phenomenon, known as the 'Weissert Event' was driven by large, sustained volcanic eruptions in the Southern Hemisphere that greatly increased carbon dioxide levels in the atmosphere and produced significant greenhouse climate effects over a prolonged time.
Published Bouncing seismic waves reveal distinct layer in Earth's inner core
(via sciencedaily.com) Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth's inner core, according to seismologists.
Published Robot helps students with learning disabilities stay focused
(via sciencedaily.com) Engineering researchers are successfully using a robot to help keep children with learning disabilities focused on their work.
Published New knowledge about ice sheet movement can shed light on when sea levels will rise
(via sciencedaily.com) The trawling of thousands of satellite measurements using artificial intelligence has shown researchers that meltwater in tunnels beneath Greenland's ice sheet causes it to change speed, and in some places, accelerate greatly towards the ocean. This can increase melting, especially in a warming climate, which is why the study's researchers think that it is important to keep an eye on.
Published Climate: Lessons from the latest global warming
(via sciencedaily.com) 56 million years ago, the Earth experienced one of the largest and most rapid climate warming events in its history: the Paleocene-Eocene Thermal Maximum (PETM), which has similarities to current and future warming. This episode saw global temperatures rise by 5-8°C. It was marked by an increase in the seasonality of rainfalls, which led to the movement of large quantities of clay into the ocean, making it uninhabitable for certain living species. This scenario could be repeated today.
Published New technology revolutionizes the analysis of old ice
(via sciencedaily.com) Ice cores are a unique climate archive. Thanks to a new method, greenhouse gas concentrations in 1.5 million year old ice can be measured even more accurately.
Published European summer droughts since 2015 were most severe over centuries -- but multi-year droughts also happened in the past
(via sciencedaily.com) The 2015--2018 summer droughts have been exceptional in large parts of Western and Central Europe over the last 400 years, in terms of the magnitude of drought conditions. This indicates an influence of human-made global warming. However, multi-year droughts have occurred frequently in the 17th and 18th century, although not as severe.
Published What do early Earth's core formation and drip coffee have in common?
(via sciencedaily.com) A new technique provides fresh insight into the process by which the materials that formed Earth's core descended into the depths of our planet, leaving behind geochemical traces that have long mystified scientists.
Published Before global warming, was the Earth cooling down or heating up?
(via sciencedaily.com) A review article addresses a conflict between models and evidence, known as the Holocene global temperature conundrum.
Published Smash or pass? This computer can tell
(via sciencedaily.com) Could an app tell if a first date is just not that into you? Engineers say the technology might not be far off. They trained a computer to identify the type of conversation two people were having based on their physiological responses alone.
Published Record low sea ice cover in the Antarctic
(via sciencedaily.com) Original source There is currently less sea ice in the Antarctic than at any time in the forty years since the beginning of satellite observation: in early February 2023, only 2.20 million square kilometers of the Southern Ocean were covered with sea ice.
Published Compact, non-mechanical 3D lidar system could make autonomous driving safer
(via sciencedaily.com) A new system represents the first time that the capabilities of conventional beam-scanning lidar systems have been combined with those of a newer 3D approach known as flash lidar. The nonmechanical 3D lidar system is compact enough to fit in the palm of the hand and solves issues of detecting and tracking poorly reflective objects.
Published New AI technology could change game prep for Super Bowl teams
(via sciencedaily.com) New artificial intelligence technology being developed by engineers could significantly cut down on the time and cost that goes into film study for Super Bowl-bound teams (and all NFL and college football teams), while also enhancing game strategy by harnessing the power of big data.
Published AI can predict the effectiveness of breast cancer chemotherapy
(via sciencedaily.com) Engineers have developed artificial intelligence (AI) technology to predict if women with breast cancer would benefit from chemotherapy prior to surgery.
