Penelitian baru berhasil mengetahui bagaimana ingatan jangka panjang bisa terbentuk. Peneliti berharap penemuan itu bisa membantu ilmuwan mengembangkan cara perawatan berhubungan dengan ingatan.

Studi itu dilakukan oleh peneliti di Wake Forest University School of Medicine.

"Meskipun sudah diketahui ingatan terbentuk dari pengalaman berulang, tapi tidak banyak yang diketahui bagaimana ingatan terbentuk hanya dengan satu paparan," kata Ashok Hegde Ph.D, ketua penelitian itu.

Ilmuwan sudah tahu orang cenderung mengingat secara tajam peristiwa yang membahagiakan maupun yang sedih karena hubungan emosional. Emosi yang ekstrim akan melepas zat kimia ke otak disebut norepinephrine yang berhubungan dengan adrenaline. Zat norepinephrine ini dalam satu hal membuat ingatan lebih panjang.

Sebagai contoh, orang akan cepat ingat peristiwa serangan teroris. Karena peristiwa itu merupakan tragedi.

Namun studi yang dilakukan oleh Hegde dan koleganya mencari tahu bagaimaan kerja norepinephrine. Tim mencari tahu apakah zat itu membantu tikus betina mengingat bau pasangan jantannya hanya dalam satu kali kawin.

Studi itu mendapati, sirkuit syaraf mengaktifkan olfactory bulb, tempat ingatan bau jantannya disimpan. Peneliti mendapati norepinephrine dilepas saat tikus kawin, mengaktifkan enzim yang disebut Protein Kinase C (PKC) terutama alpha isoform PKC di olfactory bulb. Enzim PKC ada di otak berbagai mamalia termasuk manusia.

"Kenyataan PKC-alpha diaktifkan saat keluarnya norepinephrine adalah penemuan penting. Itu menjelaskan bagaimana terbentuknya ingatan yang kuat,” kata Hegde.

wangi bunga mawar bisa menguatkan ingatan

Dalam hal ini percobaan dilakukan terhadap 74 orang sukarelawan sewaktu bermain memasang-masangkan objek di dalam komputer hingga tuntas.

Saat bermain, sebagian orang menghirup semerbak wangi mawar. Masing-masing kemudian diminta memejamkan mata hingga tidur dengan kepala di dalam tabung MRI (Magnetic Resonance Imaging) . Alat pencitra magnetic ini digunakan untuk mengamati aktivitas otak setiap orang selama tidur. Sepanjang tidur, Born juga memberikan aroma mawar kepada beberapa orang.

Di keesokannya, mereka diuji lagi dengan permainan yang sama. Ternyata pada orang yang saat tertidur mencium wewangian bunga mawar, dapat mengingat posisi pasangan kartu dengan tingkat ketetapan rata-rata hingga 97,2 %. Sedangkan yang tidak mencium aroma mawar dapat mengingat dengan ketepatan hingga 86 %.

Hal ini memberikan bukti bahwa aroma mawar dapat merangsang kerja memori otak bahkan saat seseorang sedang tidur.

Dan penelitian ini terus dikembangkan sampai pada taraf binatang. Pada tiku dan burung kicauan, dimana tikus dapat menemukan jalan keluar labirin dan burung dapat kemampuan baru dalam berkicau.

Hmm.. mawar..mawar.. walaupun dalam tv ente kejam (sinetron mawar dan melati) tp canggih juga ya bs kayak gitu.. beli mawar dan letakin dalam ruangan, akh..

Record setters

Earlier this week, the world's shortest man, He Pingping, age 21, died after developing chest pains while filming a television show in Italy. Pingping suffered from primordial dwarfism, a condition which kept him from ever growing taller than 73 cm (2 feet 5 inches) tall. Pingping was recognized by the Guinness World Records organization, who also held a 'World Records Day' last November, encouraging people all over the world to set their own records. Collected here are a group of superlatives, recent photos of world records and record attempts around the world.

Robots, part III

Robots continue to grow in their importance amongst law enforcement, military use, medical research and care, space exploration and entertainment, among other tasks. Robots recently in the news include Russia's decades-old Lunokhod rovers - recently photographed from Lunar orbit, the naming of 'Curiosity', NASA's next Mars rover, and a robotic dental patient, designed for realistic training. Collected here are a handful of relatively recent photographs of robots around the world - and the solar system.

Earth Hour 2010

Beginning in Sydney, Australia three years ago, Earth Hour has grown into a global observance. States, large organizations and individual people observed Earth Hour 2010 on Saturday March 27th, as homes, office towers and landmarks turned off their lights for an hour starting at 8.30 pm local time to raise awareness about climate change and the threat from rising greenhouse gas emissions. Collected here are a series of before-and-after photographs from this year - which (starting with the second one below) will fade between 'on' and 'off' when clicked.

Journeys to the International Space Station

April 12th marked the 49th anniversary of human spaceflight, when Yuri Gagarin became the first person to orbit the Earth in 1961. At this moment, 13 humans are currently in low-Earth orbit, aboard the International Space Station. Several were already aboard the ISS when a Soyuz TMA-18 brought a fresh crew up from the Baikonur Cosmodrome on April 2nd - they were later joined by the crew of the Space Shuttle Discovery on the 131st shuttle mission to date (only three remaining launches scheduled). NASA recently signed a new deal with Russia for six more round-trips to the ISS, at a cost of $55.8 million per seat. Collected here are recent photos of the Space Station, its current crew, their launch vehicles, and the views from above.

The seven-member is delivering the multi-purpose logistics module Leonardo, filled with supplies, a new crew sleeping quarters and science racks that will be transferred to the International Space Station's laboratories. The crew also will switch out a gyroscope on the station's truss, install a spare ammonia storage tank and retrieve a Japanese experiment from the station's exterior. (NASA/Tony Gray and Tom Farrar)

Earthquake in Yushu, China ( GEMPA BUMI )

On April 14th, residents of China's remote Yushu County, located on the Tibetan plateau, were awoken by a magnitude 6.9 earthquake. In the sparsely populated villages and the larger town of Gyegu, thousands of wood-earth buildings collapsed and many larger structured heavily damaged or destroyed. The region is difficult to reach for the response teams of the Chinese government outside aid groups - lying at an elevation of 3,700m (12,000 ft) and connected by few roads, most of which were damaged in the quake. Chinese state media now says the death toll has risen to 1,144. Rescuers continue to search for survivors as homeless residents work to recover what they can and set up shelter from the freezing overnight temperatures. (36 photos total)

As ash from Iceland's Eyjafjallajokull volcano continued to keep European airspace shut down over the weekend, affecting millions of travelers around the world, some government agencies and airlines clashed over the flight bans. Some restricted airspace is now beginning to open up and some limited flights are being allowed now as airlines are pushing for the ability to judge safety conditions for themselves. The volcano continues to rumble and hurl ash skyward, if at a slightly diminished rate now, as the dispersing ash plume has dropped closer to the ground, and the World Health Organization has issued a health warning to Europeans with respiratory conditions. Collected here are some images from Iceland over the past few days.

Earth Day 2010

Yesterday was Earth Day, since 1970 it's been a day set aside to remember and appreciate the Earth's environment, and all of our roles within it. As a way to help appreciate and observe our environment, I've collected 39 recent images here, each a glimpse into some aspect of the world around us, how it affects and sustains us, and how we affect it. Here's hoping everyone had a great Earth Day yesterday.

The most detailed true-color image of the entire Earth created to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer of our planet. Much of the information contained in this image came from a single remote-sensing device-NASA's Moderate Resolution Imaging Spectroradiometer, or MODIS.

INDIA YANG HEBAT

Sebagai pesaing utama dalam gelombang ekonomi dunia, India adalah negara yang sangat unik dan memiliki segala kepakaran untuk muncul sebagai negara kuasa ekonomi bersama dengan China. Dengan transformasi ekonomi yang pesat membangun, India turut memiliki cukup ramai golongan muda yang pakar dalam berbagai bidang teknologi dan computer.

Bukan sedikit syarikat global yang menjadikan negara India sebagai ‘hub’ perusahaan mereka, malah orang India sering bekerja sebagai ‘specialist’ dalam perusahaan-perusahaan besar dunia. Ini bukan sahaja kerana orang India memiliki kecenderungan yang tinggi dalam bidang teknologi, tetapi juga mereka mempunyai budaya kerja yang menakjubkan. Di Amerika sahaja, ada lebih 38% doctor dan 12% ahli Ilmuan yang berketurunan India. Kerana pendidikan mereka telah mencipta nama di Amerika dan Dunia.

Suatu perkara dasar yang harus kita contohi India adalah ‘pendidikan’. Pemimpin dan rakyatnya sama-sama memberi penekanan yang kuat terhadap pendidikan mereka. Sebab itu pendidikan sudah lama berbudaya dalam kehidupan orang India. Universiti atau Kolej di India, meskipun dengan infrastruktur yang sederhana. Tapi R&D (Research and Development), sistem pendidikan dan pencapaian mereka adalah yang diiktiraf dan dikagumi dunia.

Seperti juga Mahatma Ghandi, seorang tokoh India yang hebat. Mahatma Ghandi bukan sekadar kebanggaan India, tapi juga menjadi ‘ikon demokrasi’ kebanggaan dunia. Secara peribadi saya turut meminati tokoh ini dan tidak pernah bosan membaca berulang buku-buku atau Biografi tentang Mahatma Ghandi.

Ulasan ini mungkin amat sedikit berbanding kejayaan sebenar India, semoga dapat memberi gambaran yang besar tentang India yang dinamis. Agar kita dapat mencontohi dan belajar sebanyak mungkin dari kehebatan India. Apalah ertinya slogan ‘ultra-nationalism’, kalau sekedar menjadikan kita semakin dangkal dan ketinggalan ditengah-tengah arus ekonomi global.

Kita ada pilihan, untuk ‘bergerak bersama’ atau jadi penonton saja.
