Elusive Whales Set New Record for Depth and Length of Dives Among Mammals
A new study of elusive Cuvier’s beaked whales shows they can dive to nearly 10,000 ft (3,000 m).

A new long-term study looking at the elusive Cuvier’s beaked whale reveals the deepest and longest dives ever seen among mammals.
The new records indicate behavior that is much more varied and extreme than scientists expected for this species, says Simone Baumann-Pickering, a marine mammal biologist at the Scripps Institution of Oceanography in La Jolla, California. One exceptional whale dove to 9,816 feet (2,992 meters), while a second stayed down for 138 minutes.
Scientists and the U.S. Navy are especially interested in these whales because sonar activity has stranded individuals on beaches in the Mediterranean Sea, the Canary Islands, and the Bahamas, says Greg Schorr, a research biologist with the Cascadia Research Collective in Olympia, Washington…

Do you favor manors and mansions or studios and bungalows? Whatever your preferred housing style is, this graphic will help you look in the right place. The map displays the median number of rooms in housing units for each county. The five highest and lowest medians are listed. For reference, the median for the entire U.S. is 5.5 rooms.
The darker areas tend to have roomier housing units. These include parts of the Mid-Atlantic, the Midwest, and Central Plains. The latter may be due to large farmhouses. There are also specific hotspots in some states (e.g., Utah, Georgia, and Tennessee) that have higher medians. Of the 25 counties with medians of at least seven rooms, eight are in Virginia, four are in Maryland, and three are in Utah. No other state has more than two.
On the other end of the spectrum, smaller housing units with fewer rooms are primarily found in Alaska. There are 15 counties with medians of less than four; ten are in Alaska, two in New York, and one each in Texas, Arizona, and Hawaii.
The violin plot shows the distribution of numbers of rooms using percentages of housing units in each county with one, two, three…all the way up to nine or more rooms. The dots in the bars are the medians. So in a typical U.S. county, approximately 2.5% of housing units have only one or two rooms. Close to a quarter (22.8%) have five rooms, and just under a fifth (19.7%) have six rooms. The roomiest housing units (with at least nine rooms) account for 9.2% of homes.
Keep in mind that bathrooms are not counted in these data. For those interested in the definition of a room (from https://ask.census.gov/faq.php?id=5000&faqId=7433):
“When counting the number of rooms in a home for the American Community Survey (ACS), please count rooms separated by built-in archways or walls that extend out at least 6 inches and go from floor to ceiling. Include only whole rooms used for living purposes, such as living rooms, dining rooms, kitchens, bedrooms, finished recreation rooms, family rooms, enclosed porches suitable for year-round use, etc.
DO NOT count bathrooms, kitchenettes, strip or pullman kitchens, utility rooms, foyers, halls, open porches, balconies, unfinished attics, unfinished basements, or other unfinished space used for storage.”

Hidden away on the remote island of Iriomote in Okinawa Prefecture, Japan, you can find the small beach of Hoshizuna no Hama. The name translates to “star sand beach” accredited to the star shaped sand like formations that can be found there. The star shapes are the exoskeletons of a tiny one-celled organism, barely a millimetre across, called Baclogypsina sphaerulata. These protozoa have 5 or 6 pointed arms that help them move from place to place and accumulate some of the diatoms which they eat. The outer shell is made of calcium carbonate, and when they die, they leave their star shaped exoskeleton behind to be washed up on the beaches.

Hearts are pretty cool, you guys. They pump a bunch of blood around the body and keep you alive or something.
Thanks, hearts! Keep on doing that thing that you do.

light pollution is largely the result poorly designed lighting, which wastes energy shining outward to the sky, where it is unwanted, instead of downwards to the ground, where it is needed. billions are spent each year on unshielded outdoor lights, though they are directly responsible for 14.7 million tons of carbon dioxide waste in the u.s. alone.
our overlit cities and suburbs have radically altered the light rhythms to which many forms of life, including diurnal animals such as ourselves, have adapted, disrupting the migratory, reproductive and feeding cycles of nocturnal creatures in potentially devastating ways.
light, for example, makes nocturnal animals easier prey, and acts as a magnet for birds, with the latter effect so powerful that scientists speak of some birds being literally “captured” by searchlights, circling in the thousands until they drop. the effect was notably observed in new york’s tribute of lights.
the effect on humans is just as profound. darkness is not only essential to our biological welfare (with light pollution linked to breast and prostate cancer), but the light of the stars and the rhythms of day and night is part our collective evolutionary and cultural patrimony. yet, two thirds of humanity live under skies polluted with light, while one fifth of the planet can no longer see the milky way.
Caracal also known as desert lynx, can survive for long periods without water. Their ears are larger than other big cats, allowing them to navigate preys and escape danger better. They are known for their bird-catching abilities and because of their good sense of hearing they can easily detect birds flying, even birds with specially adapted feathers for silent flight like owl. Altogether, with their long legs and big paws they can leap up into the air to successfully catch their prey.
This fancy machine just broke the world record for solving a Rubik’s cube. While pathetic humans can take minutes to get the job done, the CUBESTORMER 3 takes just 3.25 seconds.
What I like about the CUBESTORMER 3 isn’t just the name (you’d say it in ALL CAPS in your mind even if it wasn’t already in ALL CAPS). It’s the look. Most functional robots tend to look spindly, valuing practicality over appearance. The CUBESTORMER 3 instead looks like something that would roll off the production line at Skynet.
