What to Do With a Day Off
If you're fortunate enough to have today off from work, the most important thing on your to-do list is to actually take the day off. Studies have shown that people send only 40 percent less email on holiday Mondays compared with regular Mondays.
Evaluate your career.
When was the last time you were completely honest with yourself about your career and whether you're doing what you want to be doing?
Have a family meal.
“I'll get to it sometime." Yeah, yeah, it's what we all tell ourselves to get out of doing the things on our to-do list that are hanging over our heads. But today is a great day just to get it done! Send that email, finish up that task at home, send that holiday thank-you note you still haven't gotten around to. Whatever it is,just do it.
A.You'll feel so much better,I promise. |
B.It might even make you more productive at work this week. |
C.It can be tough to get the whole family together for a meal. |
D.Besides, taking time to let your brain rest and recover makes you better at problem-solving. |
E.Spend more quality time with your family by having a family meal. |
F.If you're like most people, probably not recently. |
G.Do that one thing you've been putting off. |
Background noise—like the chatter in a coffee shop or the drone of passing traffic—might slow our reading speed, but according to a study of Russian readers, it doesn’t

The second theory is the good enough model; that’s when our brains aren’t analyzing every single detail of a text but instead only grabbing enough words for a ‘good enough’ understanding. By focusing less on the precise words, our brains can

Scientists have discovered more than 5,000 new species living on the seabed in an untouched area of the Pacific Ocean that has been identified as a future hotspot for deep-sea mining, according to a review of the environmental surveys carried out in the area.
It is the first time the previously unknown biodiversity of the Clarion-Clipperton Zone (CCZ), a mineral-rich area of the ocean floor that spans 1.7m sq miles between Hawaii and Mexico in the Pacific, has been comprehensively documented. The research will be critical to assessing the risk of extinction of the species, given contracts for deep-sea mining in the near-pristine area appear imminent.
Most of the animals identified by researchers exploring the zone are new to science, and almost all are unique to the region: only six, including a carnivorous sponge and a sea cucumber, have been seen elsewhere.
Contracts for mining exploration in the CCZ have been granted to 17 deep-sea mining contractors in an area covering 745,000 sq miles. The companies, which are backed by countries including Britain, the US and China, want to dig for minerals including cobalt manganese and nickel in part to sell to the alternative energy sector.
To better understand the impact of mining this fragile ecosystem and its newly discovered inhabitants, an international team of scientists has built the first “CCZ checklist” by compiling all the records from expeditions to the region. Published in the journal Current Biology, it includes 5,578 different species, of which an estimated 88% to 92% had never before been seen.
To study and collect specimens (样品) from the ocean floor, biologists have joined research cruises in the Pacific that send remote-controlled vehicles to traverse (穿越) the seabed 4,000 to 6,000 meters below. Adrian Glover, a deep-sea biologist at the NHM and senior author of the study described it as an “incredible privilege”. The expedition, funded through the Natural Environment Research Council and others, is backed by UK Seabed Resources (UKSR), a deep-sea mining company that operates the UK’s exploration area. The scientists watch operations by video link direct from the boat as new species are gathered by remote control vehicles in the darkness below.
The seabed, Glover said, is an “amazing place” where, despite the extreme cold and dark, life thrives. “One of the characteristics of the abyssal plain is the lack of food, but life has a way of persisting down there,” he said, “It’s a mystery.” One of the deep-sea animals discovered was nicknamed the “gummy squirrel”, because of its huge tail and jelly-like appearance, he said. There are also glass sponges, some of which look like vases.
With approval for deep-sea mining looming, Glover said he believed it was “imperative that we work with the companies looking to mine these resources to ensure any such activity is done in a way that limits its impact upon the natural world”.
